How and how to fix the profile

Here at "All about the Roof," we cover all the information you require to maintain and fix your roof. Metal roofing is one typical roofing material you may come across; it usually takes the form of corrugated metal panels or sheets called profiles. These profiles are well-liked because of their toughness, resistance to weather, and streamlined design. But even the hardest roofs can experience deterioration over time. If the profile on your metal roof needs to be repaired or has been damaged, knowing how to do it correctly is essential.

Typically, fixing a metal roof profile entails taking care of problems like leaks, dents, or loose panels. It’s critical to determine the extent of the damage before beginning any repairs. Look for evidence of corrosion, cracks, or places where water may be leaking through the roof. Early detection of these problems can reduce damage and improve the efficacy of repairs.

Light pounding or the use of a rubber mallet can often straighten out small dents or bends in the metal profile. Take care not to use excessive force as this might result in further harm. Roofing sealant or specialty metal patches made to stick firmly to the roof’s surface can usually be used to repair small holes or punctures that are causing leaks.

Large dents or severe corrosion are examples of more severe damage that might require replacing the damaged panels entirely. This procedure entails taking out the damaged panels with care, making sure the supporting framework is solid, and then firmly putting in new panels. Your roof’s longevity and integrity are largely dependent on its installation.

How are the corrugated board is attached to the roof

Special self-tapping screws with EPDM laying are the best mount for corrugated board. An elastic sealing ring composed of synthetic rubber that has been modified is called a gasket. The washer is firmly pressed to the EPDM leaf’s surface when the roofing screw is tightened, sealing and laying the mounting location. This keeps air and moisture out of the hole. Additionally, corrosion cannot occur in the absence of these two elements.

A roofing profileist should not be attached to shutrups with a press-shame, which are occasionally used for the installation of corrugated board for cost savings. There will always be a space between the screw head and the roof sheet, no matter how tightly they are screwed. And water will fall in it with every rain and especially after the snow melts. As a result, a professional fastener of this kind is conditional. It will cause foci of corrosion to appear in the places of attachment three to five years after the roofing is installed.

Types of roofing screws

Two kinds of screws are used for corrugated board installation, depending on the material of the crate:

• on wood;
• on metal.

Wood self-tapping screws were used to fasten a profiled sheet to a crate made of a beam, boards, OSB stamps, and plywood. Because of their relatively large thread step, self-tapping screws hold well in wood that has a slight density since they compact the material slightly.

There is either a small drill bit or just a tip at the end of the wood screws. The screw needs to penetrate the profile before it can be fixed. As a result, you can use a drill to install thicker corrugated board fasteners and a self-tapping screw with any tip for fastening sheets that are between 0.5 and 0.7 mm thick.

U-shaped metal fasteners There is more activity in the thread. This enables them to be firmly fixed in the metal even though the pipe wall’s thickness is minimal.

The metal screws’ tips are always shaped like drill bits. Furthermore, this drill is larger than wood fasteners. This is required because the self-tapping screw needs to penetrate both the 2- to 2.5 mm thick pipe wall and the corrugated board itself.

Regardless of the material they are meant for, every roofing screw available in the Russian market has a hexagonal head. A screwdriver makes it easy to screw these fasteners.

Occasionally, universal self-tapping screws with a slot directly carved into the hexagon are available. You can twist them by hand as well as with a screwdriver. On the other hand, manual installation is not the best option because corrugated board is typically fastened to a large surface area’s roof. Hand-twisting screws adds three to four times to the work time.

There are two common diameters for roof screws: 4.8 mm and 5.5 mm. When installing profiled sheeting on a metal crate—which includes arched structures—and joining the sheets together, 5.5 mm fasteners are typically utilized. However, 4.8 mm wood crates work better when fixing corrugated board to a roof.

The screw sizes range from 19 mm to 90 mm, with the longest ones being 25 mm, 35 mm, 50 mm, 60 mm, 65 mm, 70 mm, and 80 mm. Release fasteners and atypical lengths up to 250 mm. However, this is a specialty fastener and is not utilized when installing a profiled sheet on a private residence’s roof.

How to choose high -quality fasteners for corrugated board

The self-tapping screw that holds the corrugated board to the roof and breaks through the metal sheet has a significant impact on the overall durability of the roof. When screwing, it’s crucial that the screws stay tight next to the profiled sheet’s surface, don’t rust over time, and enter the crate smoothly.

Consequently, pick corrugated board fasteners. Here are a few characteristics of high-quality screws:

1. The stigma on the hat. There should be a marking on a good self -tapping screw – usually it is a letter or manufacturer’s trademark. If there is no stigma, then this should be alert: the quality of Noname products is always a lottery, and we do not recommend playing it.
2. Zinc layer with a thickness of at least 12 microns. If the layer of zinc is smaller, the self -tapping screw can begin to quickly rust. Galvanizing thickness can usually be viewed on the packaging.
3. Elastic gasket with a thickness of at least 2 mm. So that the EPDM laying can reliably seal the mounting location, it should be thick enough, spring and keep the shape well.
4. Uniform coloring without cracks and chips. The heads and pucks of self -tapping screws are often painted in one of the flowers according to RAL so that they do not stand out against the background of corrugated board. Since this is also additional protection against corrosion, defects are unacceptable on this coating.

Squeezing the puck with the laying pliers slightly is the simplest method to assess the fastener quality on a profiled sheet. Following that, the paint on the surface should not chip, the gasket should promptly regain its shape, and it should stay firmly attached to the washer.

How to correct the corrugations on the roof properly

Long-lasting corrugated board roofing requires not only the use of premium materials and fasteners but also adherence to fastening guidelines and procedures. It’s simple to fix the corrugations of corrugated board on the roof; just read our comprehensive instructions and get to work.

Preparation for the fastening of corrugated board on the roof

The metal is primed and painted in two layers, and the wooden crate is treated with fire retardants and an antiseptic prior to the corrugated board installation. When the crate is totally dry, you can start attaching the roofing profiled sheet. Usually, this takes a day. A partially wet crate may cause a metal sheet to corrode more quickly.

The corrugated board can be fastened starting from any end of the roof, but the sheets are only attached by the side that is covered to the edge. The roofing profiled sheet’s covering side can be easily identified because it is always completed on the covered side and lacks a capillary groove. The width of a typical corrugated board covers extreme corrugation.

The extreme sheets are aligned along the pediment and cornice overhang prior to screwing the profile onto the roof. The sheet should protrude from the end if the angle between them is not straight because it will be easier to cut or bend there because the corrugated board is closed with an end bar. Proceed to the sheets’ direct mount after aligning them.

Basic rules for attaching a roofing profiled sheet

Here’s how to correct the roofing professional:

1. When screwing the first screws, it is necessary to adjust the torque of the screwdriver so that the screwed fasteners tightly press the gasket to the sheet, but does not squeeze it out of the washer.
2. Self -tapping screws are twisted strictly perpendicular to the crate. If the self -tapping screw has come crookedly, it needs to be twisted, because in this case the puck will not be able to evenly press the gasket and the mounting site will not be sealed. It is possible to screw another self -tapping screw in the same place only if it is larger than the previous.
3. Self -cutting presses must be constantly monitored. Metiz can get into a dense site, for example, with a bitch, which will remain unfinished. In this case, it is necessary to once increase the restriction of the rotating moment, to spin the self -tapping screw, and then return the restriction back and fasten the corrugated board on the roof further.
4. The profile is mounted with longitudinal overlap in one wave and with a transverse overlap at least 200 mm.
5. At the place of longitudinal overlap, the screws are twisted into the top of the waves with a step of not more than 500 mm. In this case, the deflection of the sheet is unacceptable.
6. According to the rest of the area, the screws are screwed into the bottom of the profile through the wave.
7. In places of transverse overflows, screws are twisted into each wave.

The method used to secure the profile to the roof determines how many self-tapping screws are needed. For corrugated roofing board, 8–12 screws are typically needed for every square meter. Simultaneously, for basic single-sloping or gable roofs with a minimum number of pipe passes and ventilation shafts through a roof, the consumption of 8 screws per 1 m 2 roofs is relevant. Additionally, for roofs with complex shapes, 12 screws are used per square meter.

Metal roofing, sometimes referred to as profiled roofing, needs to be fixed with precision and the appropriate equipment. Make sure you have the necessary supplies, including extra panels if necessary, before you begin. Wear the proper safety gear, such as gloves and goggles, because your safety is your top priority.

Start by determining which part of the roof is damaged. Look for dents, missing or loose screws, and any places where the panels may have moved. To reach the roof securely, use a ladder and good footing. After the damaged panel has been located, carefully remove any screws or other fasteners holding it in place.

After that, carefully raise the overlapping panels above the damaged area to reveal the entire scope of the issue. During this process, take care not to bend or further damage nearby panels. If the damage is severe or irreparable, you should think about getting an expert roofer to evaluate the situation.

To guarantee a smooth surface for the replacement panel, clean the area underneath the damaged panel after removing it. Before installing the replacement, check the underlying structure for any evidence of corrosion or damage that needs to be fixed. If necessary, replace any damaged underlayment or insulation.

To guarantee a seamless fit, carefully align the new panel when installing it with the old panels. Employ the proper fasteners or screws meant for metal roofing, making sure they firmly penetrate the roof’s structure without being overtightened, which could lead to damage. Verify the alignment one more time and make sure the panel is flush with its neighbors.

Finally, look for any problems or possible leaks throughout the entire repaired area. To make sure the repair is waterproof, run water over the repaired area. Your metal roof can last longer with routine care and prompt repairs, shielding your house from the elements for many years to come.
