Ondulin roof: DIY installation

Considering doing your own Onduline roof installation? You’ve arrived at the ideal location! Due to its reputation for strength, portability, and simplicity of installation, onduline roofing is a well-liked option for both homeowners and do-it-yourselfers. Whether you’re starting from scratch or replacing an old roof, knowing the fundamentals will help you approach the project with confidence.

Onduline roofs have a unique appearance and superior weatherproofing thanks to their tightly interlocking corrugated bitumen sheets. Be sure you have all the equipment and supplies needed before you get started. These usually consist of Onduline sheets, screws or nails, a saw for cutting sheets to size, a drill bit set, and safety equipment like goggles and gloves.

Prepare the roof surface first. Make sure the surface is smooth, dry, and clean, and remove any outdated roofing components. In order to guarantee that the new Onduline sheets adhere correctly and create a tight seal against the elements, this preparatory work is essential. To prevent further problems, take your time completing this step.

Next, start at one edge of the roof and work your way to the other as you lay the Onduline sheets. It is best to overlap the sheets in order to stop water seeping through. To firmly fasten the sheets in place, follow Onduline’s recommended fasteners and spacing guidelines. Observe any particular guidelines that may pertain to pitch and orientation.

Trim sheets as you go to fit around chimneys, vents, and other roof protrusions. This keeps the integrity of the roof intact and guarantees a tidy and professional finish. When cutting, use caution to prevent damaging the sheets, and put on the proper safety gear to keep yourself safe from flying debris.

Check the entire roof once the sheets are installed to make sure there are no loose fasteners or any areas that might need more sealing. For your Onduline roof to last as long as possible and to effectively withstand inclement weather, proper installation is essential. You can benefit from a long-lasting and attractive roof that raises the value of your house if you pay attention to detail and adhere to manufacturer instructions.

Technical parameters of Ondulin

The only advantage is the relatively low coating cost. Why relatively low cost? Everything is simple. It is necessary to take into account not only the price of materials, but also the total operating costs of the maintenance of the building. And here there are big problems. Ondulin is made from the waste paper, after crushing the mass is dried, impregnated with bitumen and painted. To give a wavy shape, the sheets are pressed. Such material cannot be durable and durable, over time the extreme waves are bent, snow is blown in these places or water leaks appear. It is very difficult to repair an ondulin roof, sheets cannot withstand the weight of the builders. In addition, the surface burns out, slopes lose their attractiveness.

The shortcomings of Ondulin

1. The complexity of installation. Even under normal temperature conditions, ondulin does not have the required rigidity, during fastening, walking on it is strictly prohibited. And if the weather is sunny, then the surface of the dark sheets is very heats up, the strength drops almost to zero, it is problematic to score in such material with the desired effort, the crests are immediately crushed. And at temperatures below minus five degrees, the material becomes fragile, which also significantly complicates roofing work.

Ondulin stands out due to its intricate installation process.

The result of incorrect installation

The roofing material poses a fire risk.

Ondulin rapidly becomes less attractive.

Expert builders advise against using ondulin for anything other than non-incompatible structures, such as car canopies and outbuildings, unless absolutely necessary. D. Use material in an economically inappropriate way when arranging the roofs of residential buildings. And a lot of questions will be raised when such houses start to appear in a few years. The roof will eventually need to be replaced, which will drive up the overall estimated cost of the home.

Step -by -step instructions for laying Ondulin

Take a look at this quick fix for a suburban building to see why applying ondulin as a roofing coating is the best choice. The work won’t be expensive, and dismantling the current roof won’t add to the overall cost estimate. Furthermore, Ondulin will calmly endure the ten to fifteen years that are crucial for a building this age. You should be aware that removing outdated coatings can be quite expensive and that the rafter system is frequently harmed in the process. Another issue is that disassembly work can only be done during dry weather, and forecasts are notoriously inaccurate.

First information. A small house with a slate roof made of asbestos and cement sits in the forest near the bay’s edge. It has been there for roughly 25 years. I totally lost my natural look during this time; mosses grew on the surface, and a lot of leaves and other trash accumulated. The home’s owner made the decision to modernize the building’s exterior even though the tightness stayed the same. I made the decision to complete it fast and cheaply.

Sensible guidance. Following an initial assessment of the slate roof’s condition, the master chose not to remove the old slate because it was dangerous, time-consuming, and expensive. Ondulin’s low weight is one of its benefits; you can install it over old coatings and the rafter system can withstand small additional efforts without the need to reinforce the supporting elements.

Another consideration was the fact that roofing is done in the late fall, when it frequently rains. Work is not weather-dependent if the building has an old roofing system. 50 m2 area with a sloped gable roof.

Step 1. Calculate the number of materials. For the crate, you will need 30 linear meters of a beam of 50 × 50 mm, for covering slopes you will need 36 sheets of ondulin. The total weight of materials is only 220 kg, which allows you to transport them in an ordinary passenger car. For fastening ondulin, it is necessary to purchase 880 nails. 20 for each sheet, and the rest are required for fastening skates (12 pcs. one meter long). The crate is fixed with self -tapping screws, for vertical bars, the length of the screws of 80 mm (240 pcs is needed.), for horizontal 70 mm (you need 300 pcs.). The dimensions of the sheets are indicated by the manufacturer on the package, and the quantity is calculated by ordinary arithmetic formulas. If it is difficult to do this on their own, then sellers will always provide practical assistance in calculating the roof and all the additional elements.

Step 2: Purchase roofing materials and place them gingerly onto a level surface. It is advised to place ondulin sheets on bars to facilitate their intake. Materials that are kept in storage for an extended period of time need to be shielded from sunlight.

Arranging sheets on bars

Step 3: Get the equipment ready. A standard hacksaw, a mounting knife, a hammer, a screwdriver, roulette, pencil, chisel, rope, and construction level are needed for the task. Discover the basic tools; each owner should have access to them. Make sure you follow the manufacturer’s instructions carefully when installing ondulin. These are only general recommendations; while the manufacturer cannot cover every scenario that might occur during roof covering, you will have a good idea.

Step 4: Construct two steps out of bars. One was standard, and the other had a hook attached to the skate. It is advised that roof work be done extremely carefully and in accordance with safety standards. Furthermore, it is not advised to walk on Ondulin, and with this unique staircase, you can work on the roof anywhere on it.

Stepladders

Step 5: Scrub the ancient slate’s exterior. You can use any makeshift tools and brushes for this; meticulous cleanliness is not necessary, but you should remove the majority of the vegetation. The truth is that mosses thrive in the least ideal environments; if they are not removed, the components of a wooden crate will soon lose their initial supporting boundaries.

Now that the setup is finished, you can begin installing the crate.

Installation of the crate

The first task should be to measure the slopes. The slopes’ edges are exactly parallel and at a right angle if the house was constructed by responsible builders. If there are discrepancies, you will need to consider the largest size when installing the crate. Check the slopes’ positions as soon as possible. The old rafter system can be significantly deviated from by eliminating the crate.

Step 1: Assemble the blanks from the crate bars using the sizes that are offered.

Breens for crates from bars

Vital. Drinks should be prepared beneath the horse on the old roof since the surfaces of the structures will be in one plane as a result. The height of the protrusions on the skating elements should match the depth of the drunk.

Step 2: Begin repairing the crate’s longitudinal bars.

Fixing the crate’s longitudinal bars

Pre-drill the holes in the slate so that the self-tapping screw will fall into the old crate. By the way, screwing screws will be much easier with these holes.

The act of fastening screws

Slate has a much higher strength than Ondulin, and self-tapping screws are extremely difficult to screw into it. Fasten the ends of the bars and draw the rope in between them.

Securing the extreme bar

It will be used to record all of the bars that are still in the crate. It is not required to thoroughly inspect the crate’s components for a number of reasons. First off, there are very few critical deflections in the old roof, which is mainly even. Second, correcting the deviations in each bar’s position is not feasible. Thirdly, depending on where the crate is positioned, Ondulin’s extremely flexible material will bend in the proper spot without any issues.

Step 3: Align the lower ends of the beam with the stretched rope to strengthen it in every fifth wave. The same method of fastening is used: the self-tapping screw is twisted only after the holes in the bar and slate have been drilled.

Bars are installed on a stretched rope.

Vital. There are special bars attached close to the chimney; it doesn’t matter how far apart they are. The primary requirement is that the bars must be in the slate’s final wave prior to the brickwork.

Step 4: Nail the horizontal bars in place. The crate’s vertical elements should all have their joints completed in the middle.

Joints between vertical bar centers

Sensible guidance. When installing two layers of asbestos-cement slate, it is necessary to do so in a bar because this will level out the differences in coating height and ensure that the crate is evenly sized. At the location of the overlap, the drink’s depth should match the thicker coating. Following the measurement, data is collected.

I had markup for

Self-tapping screws measuring 70 mm in length are used to secure the bars; at joints, these screws are positioned at a 45-degree angle. This technology reduces the possibility of thin bars cracking at the ends.

Angled screws are used in joint locations.

These measurements are typical for onedulin sheets, but the skate varies depending on the size of the slopes. The horizontal bars of the crate should be fixed with a step of 61 cm along the axes.

A 61-cm-step horizontal beam is laid.

It is advised to create two templates in order to control the spacing between the crate’s horizontal lines and to make the task easier. To check the distance between each bar, working with them is far more convenient than using a roulette wheel. The template’s length should be equal to 61 cm – 5 cm, or 56 cm, minus the width of the bars.

The work will be made easier by the template, which is a beam segment.

Horizontal bar installation

Step 5: Beat the bars to which the wind board will eventually be fixed on the outside of the roof’s ends. Strictly net them at right angles to the horizontal crate’s rails. The first leaf of the oniline coating is positioned on this parameter, which requires precise control. Furthermore, it is thought that the first sheet is the most crucial, with subsequent errors being very challenging to correct.

Bars that will eventually be fixed to the wind board

Step 6: After the bar is fixed, speak the transverse beam’s projecting ends.

Distributing the surplus for the wood

Now that the crate is ready, you can begin resting on it.

Installation of Ondulin

As was already mentioned, there are certain limitations with the roof. For example, you cannot work in extremely hot or cold weather.

Step 1: Measure the length of the sheet, which needs to be cut at the skate, by trying on the first leaf ondulin. It is important to keep in mind that the overhang should be no more than 7 cm and that the sheet overlap should be approximately 14 cm when fitting. It is required to provide a removal for each wave in order to fix the wind board.

Method for mounting sheets

There should be only a 7 cm overhang.

Step 2: Temporarily fasten two bar segments with a rope to them along the slope’s edges. Remember that the removal is 7 cm in size when attaching the segments.

The bar that the rope is going tobe fastened to

All of the lower sheets of Ondulin are installed along it by screwing the screws into the ends and pulling the rope between them. Grab the rope.

The rope’s edge is fastened to a screw.

It is possible to lessen the possibility of roof leaks forming by starting the sheet installation process on the opposite side of the prevailing winds.

The best place to start installing sheets is on the other side of the predominant winds.

As we’ve already discussed, ondulin becomes significantly softer when heated in the presence of sunlight. If the wind causes this to happen, the edges of the material will bend upward, which will eventually weaken the coating’s tightness. Naturally, the roof’s appearance will deteriorate considerably as well.

Step 3: Put on the Ondulin sheets and get ready for the top ones, which are shorter than the bottom ones. An assembly knife works better for cutting the will of the waves than a regular hacksaw for sawing the sheets that span them. The canvas needs to be periodically dipped in water to minimize sticking.

Utilizing a hacksaw to cut the sheet

Vital. It is necessary to complete the first upper sheet at half its normal width in order to avoid having four angles appear in one spot.

Step 4: Install the first lower ondulin leaf and make sure it is positioned correctly on the rope.

Arranging the sheet and determining its placement

If everything is normal, then fix the sheet. To do this, first you need to drive nails into two extreme waves of the lower row, then in the middle row. On three meters, the sheet is securely fixed, now you can drive all other nails. If it is difficult for you to get into narrow bars, then draw tags on the surface of Ondulin. To do this, use a flat board, put it on the sheet and combine the side surface with the middle of the bars. With a pencil or marker, make tags on every wave. If the nail did not get into the rail of the crate, no need to be upset. Feel free to pull it out and drive it in a new place. There will be no noticeable leaks through a small hole in the upper crest of the wave. If a few drops of rain falls into a subcutaneous space, then they will quickly dry out.

Step 5: Use a checkerboard pattern to drive the remaining nails. Take caution not to harm the coating as you work. The nail’s plastic portion ought to come into contact with the crest, not Recall it. Recall that Ondulin is not meant to handle large weights.

Fixation of sheets and diagram

Checkerboard scoring is required for nails.

The extreme wave overlaps and is fixed.

Ondulin installation, picture. Each sheet uses twenty nails.

Near the extreme wave at the same time as a sheet of the next row, remember that at least twenty nails should be used for each sheet. This amount may increase in places of the maximum possible gusts of wind. The lower row is driven into each wave, then two rows through one. Ondulin manufacturers complete their roofing material with stainless alloy nails or galvanized, the lower part has notes to increase the force of fastening the metizes. All these devices perform only one function – increase the profit of manufacturers. Ordinary nails are well held not only by ondulin, but also an ordinary slate. Experienced builders are unknown when the roof was torn due to the fact that the metal nails were completely talked. Especially under the ondulin, the material will simply break over the nails, and not pull them out of the wooden beam.

And the final one. If they are beneath the roofing material, how can they rust? If so, there is a leak here that needs to be fixed right away. Keep in mind that the horse needs at least twelve centimeters of overlap.

Throughout the whole length of the slopes, the horizontal and vertical joints should be situated on the same line; their positions should be periodically adjusted. Only after the sheet has been laid out evenly on the crate—don’t stretch it or go against the driving nail sequence—can you score nails.

Step 6: Take exact measurements of the Ondulin’s dimensions at the chimney bypass location. Sheets should fit together closely next to the pipe. Install extra crate bars to ensure a sturdy roof fixation in these areas.

Step 7: Try the final sheet to determine where the windbreaker is fixed. She should come in from behind and enter the upper wave of the sheet. Using the crate’s ends, cut through the beam; use a hacksaw to trim any excess.

Trying on the final sheet

Step 8: Attach the Ondulin leaf next to it. Note that you do not need to drive the last row of nails; this is done only after the windboard is installed.

Step 9: Attach the ondulin to the windbreaker after installing it. Put in place the cornice boards.

Now that the slopes are finished, you can start mounting the horse. Moreover, work should be done on the other side of the predominant winds in a particular area. The element is nailed to each wave of sheets where the skates overlap by at least ten centimeters.

How does the roof appear now that the skate has been installed?

Knowing the advantages and difficulties of installing an Onduline roof on your own is crucial if you plan to do it yourself. Renowned for its strength and portability, Onduline provides a useful option for do-it-yourself roofing projects. Because of how simple it is to handle and cut the corrugated sheets, even people without professional roofing experience can use it.

Make sure you have all the tools and supplies you’ll need before you begin. This consists of fasteners, Onduline sheets, a saw that can cut the sheets, and protective clothing like goggles and gloves. The installation process can be greatly streamlined and errors or delays can be prevented with careful planning and preparation.

Pay special attention to the manufacturer’s instructions when installing Onduline. A roof that has been installed correctly will last longer and be more resilient to different types of weather. Make sure the roof surface is clean, dry, and clear of debris before starting. To avoid leaks, make sure the sheets are overlapped correctly and firmly fastened in accordance with the suggested procedures.

Spend some time examining the roof after the Onduline sheets are installed to look for any cracks or places that might require more sealing or support. If you take care of these problems right away, you can keep your roof in excellent shape for many years to come and avoid more issues. To further improve durability and weather resistance, think about painting or applying a protective coating.

Recall that although installing an Onduline roof yourself can be rewarding and economical, safety must always come first. Work on dry, clear days and take safety measures to avoid accidents or falls. Consult Onduline’s comprehensive installation guides or experts for advice if you run into problems or are unsure of anything. You can successfully install an Onduline roof that complements your house and offers dependable protection if you plan ahead and pay close attention to detail.
