Frankage fastening to a wooden crate

Welcome to "All about the Roof," where we explore crucial roofing methods and perspectives to assist you in better understanding and caring for your roof. Today, we concentrate on frankage fastening to a wooden crate, which is an essential component of roofing.

For roofing to be durable and safe, materials must be properly fastened. The process of firmly fastening roofing components, like tiles or shingles, to a wooden crate structure is known as "frankenage fastening." This procedure guards against weather conditions like wind and rain in addition to guaranteeing that the roof covering remains securely in place.

The wooden crate acts as the primary support for the roof covering. It is typically made of durable materials like plywood or oriented strand board (OSB). It offers a solid foundation for securely fastening roofing materials. The strength and integrity of the roof structure are largely dependent on how well the wooden crate is installed.

Roofing materials are normally fastened to the wooden crate using specialized fasteners like screws or nails during the frankage fastening procedure. Through the roofing material, these fasteners securely anchor into the wooden crate below. These fasteners are carefully spaced and positioned to guarantee uniform weight and stress distribution throughout the roof surface.

Both homeowners and roofing professionals need to understand how frankage fastening operates. It guarantees that roofs are constructed to endure time and the elements, offering long-lasting security and comfort. You can guarantee that your roof will continue to be sturdy, safe, and dependable for many years to come by becoming an expert in this basic area of roofing.

Fixing corrugated board to runs and crate

The profiled sheet is mounted directly to a crate, also known as a special frame, on the roof. The crate is typically constructed of wood. It can be a rubberized board that is 32 mm thick and 100 mm wide, or it can be a beam that is 40 x 40 or 50 x 50 mm in size. It is advised that the wooden crate structures be treated with specialized antiseptic compositions prior to installation. By preventing wood rot, this processing greatly increases the roof service’s lifespan.

Securing a profiled sheet to a metal profile using self-tapping screws

The crate can be made of metal. For this, various metal profiles with a metal thickness of no more than two millimeters are usually used. The use of metal of larger thickness unjustifies the load on the rafter system. In addition, the fastening of corrugated board to metal runs and crate with self -tapping screws also imposes certain restrictions on the thickness of the metal. The fact is that self -tapping screws have a special drill at the end, which allows them to screw them into the metal without pre -drilling holes only if its thickness does not exceed 2 mm. Of course, the fastener of the profiled sheet to metal beams of large thickness is also possible – however, this greatly increases the complexity of the process.

With a step of 300 to 1000 mm, wooden beams or metal ruins are positioned perpendicular to the rafters. The corrugated board’s bearing capacity and brand determine the step’s size. In the case of a profiled man whose wave height is less than 20 mm, a continuous crate should be used.

Corrugated board attached to metal T-shaped runs

Fastening of corrugations on the roof with self -tapping screws – what should you pay attention to

During roof installation, the most important step is to fasten the corrugations on the roof. The longevity and tightness of the roof are dependent on how well the corrugated board sheets are fixed and laid. In no situation should you begin working if you are unsure how to fix the profile on the roof or if you haven’t figured it out completely. Avoid attempting to "figure it out along the case," as this method is nearly certain to cause material damage or a significant reduction in the roof’s operational capabilities.

Branded fasteners to fasten a roof-profiled sheet.

Special self-tapping screws are used to fasten the corrugated board to the crate. They can range in length from 20 to 250 mm and in diameter from 4.8 to 6.3 mm. Self-tapping roofing screws feature a unique non-reprovable rubber sealing goal beneath the head to guard against potential leaks in the fastening locations. You can also use flat-headed screws. Rubber gaskets for sealing have to be installed underneath the head in this situation.

Corrugated board is typically fastened to runs using special elongated screws, which isn’t always convenient. The profiled sheet’s bottom wave width must be used to determine the crate’s step in order to prevent this.

The quality of self-tapping screws should receive special attention because roof leaks are inevitable when the material used to make sealing gaskets dries out and cracks. The manufacturer’s brand is always present on the head of branded self-tapping screws. A roof’s profile fastening to the crate is generally regarded as reliable when six to eight self-tapping screws are used for every square meter.

The security station is mounted to the crate in the lower wave. In this case, its most dense fit is ensured and the possibility of leaks at the mounting site decreases to a minimum. It is necessary to lay prepared sheets with an overlap in one or two waves in a row and 100-200 mm. between the rows. In the upper and lower part of the roof, the sheet of the corrugated board is attached to the base in each wave, and in the intervals, fastening through one or two waves is allowed. Between themselves, the sheets of corrugated board are usually connected with the help of rivets. For this, special hand pistols are used.

Fastening a wooden crate with corrugated board

Self-tapping screws ought to be precisely zero degrees perpendicular to the corrugated board sheet’s plane, as any deviation could result in the sealing washer fitting loosely and potentially leaking. This is particularly crucial when the profiled sheet is fastened to the runs because there is a higher chance of a skew above because the screw length is greater in this scenario.

The horse is fastened to the crate via the sheet’s upper wave, which offers the strongest bond between the skate elements and the corrugated board. Additionally, installing sealing gaskets in the lower waves of the profiled sheet beneath the ridge is advised for roofs with minor slopes. When there is a lot of lateral rain, they keep the horse from getting wet.

Why can the roof flow, even if the fastening of the roofing profiled sheet is the right?

I explained how to repair the roof’s corrugated board above. However, careless cutting of the profiled sheet can also lead to corrosion and roof leaks, in addition to improper profiled sheet fastening on the roof. When cutting corrugated board, it’s best to use electric or manual scissors; an electrician should be called in for oblique cuts.

It is not advised to use a high-speed power tool with cutting circles. The corrugated board’s polymer coating may be harmed by the hot metal particles that fly off when cutting, which will shorten the roof’s lifespan and cause premature metal corrosion. To stop brown corrosion, the cutting areas need to be treated after the job is finished.

Furthermore, pay close attention to what you do while working because utilizing technology to fasten a corrugated board roof implies that you will be working directly on metal sheets in addition to the roof itself. As a result, it is simple to inadvertently harm the protective layer, which will hasten the roofing’s deterioration. Use soft shoes free of metal designer elements and spikes to prevent this. Additionally, attempt to avoid placing the tools directly on corrugated board; instead, place them inside of foamed materials or special boxes.

The damaged areas need to be treated with special compounds if the coating was still damaged during the corrugated board installation on the roof. Paint and superior high-resistance sealing mixtures should be used after the application of specific anti-corrosion compounds.

Waterproofing of joints and corrugated board fitting locations on the roof

In addition, if the screw holes were drilled, more processing is needed. As previously mentioned, this becomes necessary if the profiled sheet is fastened to metal runs or crates that have a thickness greater than 2 mm. Though sometimes it is not possible, I strongly advise avoiding this. In this instance, a sealing composition must be poured into the screws without fail.

It is advised to perform a follow-up broach of screws two to three months after you affixed the corrugated board to the roof. This will eliminate any potential weakening of the fastening density that might result from the corrugated board sheets shifting in relation to one another. This kind of shift can be brought about by the sheets’ alignment and adjustment during installation as well as by their deformation from sudden changes in the outside air temperature.

How to fix corrugated board on the roof correctly

Building a country home is an honorable but expensive endeavor. Because of this, the developers decide to lay the roofing material on the roof independently in an effort to save as much money as possible. One undeniable benefit of a profiled sheet is how lightweight and simple it is to install. This means that the developer won’t need to possess any specialized skills to ensure the security of the corrugated board roof, and its style won’t present any challenges.

Sprayer characteristic of a profiled sheet

Corrugated board is one of the most versatile building materials. In addition to roofing, it can be used to decorate walls, floors, and even to build both permanent and temporary fences. This material has unquestionable benefits in terms of strength, durability, environmental friendliness, and high reliability. He is not sunburned and does not require frequent painting.

Profiled sheets have an external slate-like appearance and are composed of galvanized steel with the potential for a polymer coating. They are made in a range of sizes with different anti-corrosion stability, stiffness, and strength indicators.

The following brands are available for corrugated board:

  • C – is used for the construction of light coatings, has a corrugation height from 8 to 44 mm;
  • NS – is most often used in roofing, a wave height from 35 to 44 mm;
  • H – has reinforced gesture ribs and is suitable for the capital roof, the height of the corrugation is from 57 to 114 mm.

It is advised to cover the roof using profile sheets that have a unique moisture output groove and a wave height of 20 to 60 mm. Their thickness is determined by engineering calculations that consider operational, wind, and snow loads, among other potential loads.

The availability of installation instructions for corrugated board should be confirmed before making a purchase; if not, you should get in touch with the vendor.

Every homeowner wants their roof to last as long as possible and look good for over a dozen years. Because of this, you need to take the local climate into account when selecting the appropriate profile metal. A profile of at least 20 mm and a roof slope angle of at least 15 ° should be selected for locations that receive more snowfall during the winter. The NS35 and NS 44 brands of corrugated board are the most widely used in private construction.

Basic rules for laying corrugated board

Similar to other roofing materials, profiled material is installed by overlapping sheets, the amount of which varies according to the slope’s inclination angle.

When installing corrugated board on a roof, you should follow these guidelines:

  1. With a slope of a roof of less than 14 °, a horizontal overlap of sheets is made about 20 cm.
  2. The optimal overlap of material with a roof slope from 15 to 30 ° will be 15-20 cm.
  3. Acceptable overlap with a roof steepness of more than 30 ° will be 10-15 cm.

Angle of roof tilt and hail

Vertical overlap, millimeters

Table: Corrugated board corporal’s dependence on roof slope angle

When the slope of the slopes is less than 12 °, all of the longitudinal and transverse joints are additionally "bound" with silicone or thiocol sealant, and the sheets overlap by at least 25 cm.

No matter how complicated or steep the slope is, the sheets have to be laid with an overhang behind the cornice and parallel to the previously leveled cornice along a strictly horizontal line. One self-tapping screw will be used to correctly attach the adjacent sheets, minimizing the chance that the decorative protective coating will be violated.

Prior to installing corrugated board on the roof, the size of the cornice overhang—which is determined by the profile’s height—must be measured:

  • for a profiled sheet, the depth of the wave of which is 8, 10 and 20 mm, the overhang length will be in the range from 50 to 100 mm;
  • In all other cases, the cornice overhang will exceed 200 mm.

Corrugated board is fastened to the roof using self-cutting (also known as self-tapping) screws that have a diameter of 4.8, 5.5, and 6.3 mm and a length of 19 to 250 mm. Foreign companies EKT, Hilli, Fisher, and SFS have self-cuts that have drilling beards on them, which allows them to be twisted without the need for pre-sprinkling holes. Premium roofing screws are equipped with EPDM gaskets to keep moisture out of the apertures.

The length of the cylindrical threaded portion should be taken into consideration when selecting screws; it should be at least 5 mm longer than the connected pack of sheets. Six to eight fasteners are used for every one square meter of coating.

Additionally, keep in mind that the sheets are secured to the crate using rubber sealing washers, and that screws measuring at least 28 × 4.8 mm must be inserted at the lower "waves." The horse needs to be secured with self-tapping screws of the necessary length through the upper "waves."

Condronage roof isolation device

Under the roof, condensation forms while the building is in use. It is essential to construct a roof so that the temperature outside and inside the subterranean space coincide in order to prevent moisture buildup. To accomplish this, specific structural elements must be appropriately equipped.

A condensate-preventing gasket should be made in order to prolong the roof’s service life prior to the installation of profiled sheets. The ideal membrane to use is steam-hydro-insulating, and you must begin with a cornice facing the skate. The membrane has a 20-cm step and is fastened with nails to a large hat.

There must be a required 2-3 cm sag between the rafters and a 10-15 cm overlap when installing the waterproofing film. Following the connection, adhesive tape is used to glue the overlap’s joints.

On top of the rafter legs, a 20 mm thick, 2-thick counterattack is nailed, protecting the membrane from harm while the sheets are being fastened. A 5 cm space is left between the laying and the first board to allow for air flow. The gasket’s edge is then trimmed to the top and fastened from the inside. A standard knife can be used to easily cut the gasket fabric if needed.

Ventilation holes must be installed as close to the skate as feasible to allow for the unrestricted flow of air in the undercarbon space. The following components are used to ensure proper air output:

  • ventilation ducts;
  • special gaps between the roof plate and the skate;
  • gratings for ventilation located on the ends of the building.

Wooden rails are fastened to the waterproofing membrane during the installation of ventilation gaps, which increases the amount of moisture and condensate released. Additionally, every node needs dependable fixation.

Direct consolidation of corrugated board on the roof

A certain delicacy must be observed when mounting the profile: the sheet should lie so that the hollow along its edge, not the peak, is visible. Additionally, the front side of the corrugated board should be in the capillary groove on the edge. A long rope on the roof is used to drag the roofing material over the lags.

A great "transport path" for profiled sheets can be created by turning the lengthy stairway with steps down and mounting it on the wall. The profiled sheets will slide along this path, much like they would along rails.

The laying of corrugated board is carried out by belts across the slope, and the first belt is placed with a allowance for a visor 10-15 cm. The material must be fixed with roofing self -tapping screws with a hexagonal head, in which a sealing rubber gasket is already provided. They need to screw them strictly perpendicular to the coating, excluding possible distortions. In order for the screws not to stand out on the canvas, their color must coincide with the color of the corrugated board. The fasteners of products are carried out along the edges of the sheet, in the middle and at the joints, it turns out that at least 6 screws should go on one sheet.

Along the slope, the subsequent belts of a profiled sheet are laid with a 10-cm overlap on the preceding ones. The installation of sheets proceeds up to the roof’s skate, at which point the styling ceases and a new slope from below takes its place.

A tiny staircase the length of the roof will be made possible by light movement on the roof. Making it is very easy; just fill in the spaces on the board and secure it around the skate’s corner.

A standard 40–50 cm wide galvanized strip or a unique profiled sheet, fastened with self-tapping screws, is overlapped over the roofing horse. Following installation, the roof’s surface is cleared of chips and trash, and any areas with cuts or scratches are tinted to prevent brown corrosion. It is advised to draw screws after three months because wood mounts can weaken with time.

And lastly, a few guidelines for handling corrugated board that are undoubtedly not unnecessary:

  • The fastening of profiled sheets is not allowed using nails, since there is a high probability of their separation under the influence of wind.
  • Also, welding and gas cutting of profiled sheets are also not allowed.
  • It is strictly forbidden to cut corrugated board with a “grinder”, otherwise the high temperature will burn a polymer coating with zinc, which will lead to rapid corrosion and rusty leaks. Metal scissors can only be used for longitudinal cutting of the sheet. The correct transverse section with their help will not be able to make, since they will doubt the corrugated wave. It is quite difficult to straighten the deformed sheet, but even the most thorough edit will not be able to guarantee the coincidence of profiles when laying.

Cut-off electric bars or an electrician can be used if the corrugated facilities still don’t fit the roof’s dimensions or if cutouts need to be made beneath the chimney. To cut the material, a circular saw with big winning teeth is also utilized.

Than and how to fix the corrugated board on the roof?

The choice to use corrugated board for roofing is typically based on the material’s modern attributes, which include strength, high reliability, durability, and resistance to a variety of climatic conditions. Corrugated board perfectly withstands the widest range of operating conditions and doesn’t burn out or require frequent painting.

The corrugated board roof is easy to install, reasonably priced, and provides excellent attic protection from precipitation.

Furthermore, corrugated board is highly appealing and easily fits into any architectural style of the house and its surroundings. We’ll explain how to repair the corrugated board on the roof in this article. What are the features of this process that installation will need? We will discuss the roof design and provide you with more detailed information about each component.

Roof design

The attachment scheme of corrugated board differs from many others with its simplicity. This design can build only two or three people who do not have special knowledge of a person in a short period of time, without expensive tools. Most often, profiled sheets with trapezoidal type corrugated (less often sinusoidal) are used for roofs, which are designed specifically for laying on the roof and for walls (but with a certain thickness). Material with 0.5 to 0.7 millimeters is best suited for this, with a galvanized coating and applied with a polymer layer, which will make your roof bright and will not allow the paints to burn out. The main components of the roof using corrugated board are:

Pieces of corrugated board for the roof.

  • lining (these are special membranes, often rubber linings with a form repeating the shape of the corrugation);
  • crate and wooden rails for ventilation space;
  • cornice and roofing strips;
  • Snow -off bar and snowballs;
  • internal joints;
  • through transportation;
  • seals for joints;
  • skate and end strips;
  • Elements for lending.

We’ve previously discussed the specific functions of each element and how to calculate the slope’s angle multiple times. At this point, we’ll just add that, in order to achieve high-quality styling, you must determine the total number of materials—including any additional elements—ahead of time before making a purchase. Using the most basic mathematical formulas, this is a simple task (you can read more about this in our articles on calculating the number of corrugated board for roofs).

Using self-oversporating self-tapping screws for fastening

The properties of the screw’s constituent parts.

Any fastener of corrugated board. It doesn’t matter, for walls, fences, balconies or roofs it is necessary, performed taking into account some features that we will talk about now. This is not only a crate, run, but also fasteners. It is important to choose the right type of fasteners, before proceeding with the fastening of corrugated board on the roof. Many people believe that there will be enough ordinary nails and aluminum rivets, but this is not so. Moreover, the use of such fasteners is fraught with serious damage to the material. Roofing self -tapping screws provide high strength strength, protection against flowing, rain (absolute waterproofness). In addition, the use of such fasteners far accelerates the process.

It should be noted that each sheet requires roughly eight screws, and installation is made simple and quick with the use of a screwdriver.

One thing to consider when purchasing self-tapping screws is their quality. First and foremost, stainless steel or carbon steel with a zinc coating should be used to make the sealing washer.

Plan for screw-fastening corrugated board.

When mounting (the drill should have a torque limiter) from under the washer should be about 1 mm rubber gas. The parameters of the roof screws can be like that: SW 4.8 × 28, 4.8 × 38; SL 4.8 × 20 (for overflow). The heads of self -tapping screws should be with a loop and a height sufficient for strong holding in a bit. Sealing washers are made of aluminum, have a diameter of up to fourteen millimeters, the laying itself is made of vulcanized rubber (or special elastomers). From above the head often has a colored polymer coating, so as not to stand out on the surface. Tips of self -tapping screws have a drilling part penetrating through the sheet into a crate, which provides strength and high reliability of the leaf retention.

The process of fastening the profiled sheet

Corrugated board is a universal building material that is incredibly simple to fasten. The same sheets can be used for garages, fences, facades, and roofing. Each structure has unique qualities, of course, but for the purposes of this discussion, we’ll focus on installing a profiled sheet on the roof.

How to lay a profile correctly?

The roof’s corrugated board installation method.

One of the most important issues in the construction of the roof: how to properly fix the corrugated board to ensure the strength and reliability of the entire structure? First you need to decide for what purposes the roof is built, whether it will be the roof of a residential building with a cold attic or a warm attic, a roof for a garage or outbuilding, a roof of a large industrial building, a warehouse, a store. The composition of the entire structure will largely depend on this, the selection of a profiled sheet of a certain type and thickness, as well as additional materials. Most often, a universal profile "H" is used, which satisfies all the necessary requirements; the thickness and height of the corrugation are determined individually. We must not forget that during installation, special self -tapping screws are used, which have rubber gaskets for a regular canvas and tin – for yends. Remember that the horse’s horse is attached only into the upper wave of the corrugation, while the rest of the area should be mounted only in the lower part of the wave. The fastening of the corrugated board is carried out only according to these rules and not otherwise.

Hydro- and vapor barrier

Corrugated board waterproofing cake and roof crate

Remember to use the steam and waterproofing layer device to prevent precipitation from getting on the roof. This layer will come in handy when there is a temperature differential between the inside of the house and the outside, causing condensate to form. When condensate builds up, it can seriously harm the structure. In order to remove excess moisture and condensation, ventilation gaps must be set up at this time. To do this, thin wooden rails are fastened to the waterproof film. Every node needs to be fastened firmly.

We determine the step of the crate

Typically, a wooden crate is used to profile a profiled sheet; however, the procedure may vary depending on the crate. It is dependent upon both the wave height and the angle of the roof’s slope. Examine the primary choices and guidelines.

  1. With an angle of inclination more than fifteen degrees, the crate is performed in a step of thirty -five to fifty centimeters.
  2. If the angle is less than fifteen degrees, then the crate is continuous, and the corrugated board is taken for this with the marking of C20. Neighboring sheets lay with a slight overlap in one wave (up to twenty centimeters).
  3. With angle up to fifteen degrees and corrugated board C35, the step should be from thirty centimeters, the overlap is used the same. And for the C44 corrugated board, the bar of the crate is already from fifty centimeters.
  4. With a coal of up to twenty degrees, a small overlap of ten to fifteen centimeters is provided, the crate can have a step about thirty to a hundred centimeters.
  5. With very small slopes, up to twelve degrees, the design of the roof can be different, but the use of silicone sealant for joints is mandatory, they can be fixed additionally by steel rivets.

In order to guarantee the longevity and stability of your roof, it is imperative that you fasten frankage to a wooden crate. A sturdy base for the subsequent roofing materials is created by firmly fastening the frankage, sometimes referred to as the underlayment or roofing felt, to the wooden substrate.

The proper tools and methods must be used when fastening frankage. Roofing nails or staples are typically used, depending on the kind of frankage and your roof’s particular needs. For a snug and secure fit, these fasteners pierce both the wooden crate underneath and the frankage itself.

In order to stop water from leaking through seams, frankage must be installed properly, which requires overlapping the sheets. This layer serves as a moisture barrier, preventing water damage to the wooden crate and the supporting structure. Furthermore, properly fastening the frankage keeps your roof intact during storms and strong winds by preventing wind uplift.

The frankage fastening needs to be inspected and maintained on a regular basis to maintain its effectiveness over time. Examine the frankage itself for any indications of wear or damage, and look for any missing or loose fasteners. Timely maintenance can help your roof last longer and avoid expensive water damage.
