How to attach ondulin to the sheathing

The longevity and durability of your building depend on the type of roofing material you choose and how well it is installed. Popular roofing material Ondulin provides an easy-to-handle, lightweight, and reasonably priced solution. But in order to fully benefit from it, it must be properly attached to the sheathing. Even though it’s a simple process, it needs close attention to detail to prevent common mistakes and guarantee a safe, weather-resistant roof.

Your roofing material is supported and stabilized by the sheathing, which acts as its base. Make sure the sheathing is sound, free of rot, and securely fastened before starting to attach the Ondulin. Any sheathing damage or instability can jeopardize the roofing system as a whole, resulting in leaks or other problems later on.

After preparing the sheathing, you can begin arranging the Ondulin sheets. Careful measuring and alignment are required in this step to guarantee that every sheet fits precisely and overlaps with its neighbors. In order to keep water out of the roof and make sure it can withstand the weather, proper overlap is essential.

Using unique nails or screws made for this material is required to secure the Ondulin sheets. The manufacturer’s instructions should be followed when placing these fasteners at regular intervals. To preserve the integrity of the roof and stop any possible leaks, it is essential to make sure the nails or screws are inserted straight and to the proper depth.

By following these guidelines, you can have an Ondulin roof installed correctly that will not only look good but also offer dependable protection for many years to come. You can maximize the lifespan and performance of your roofing investment by taking the time to do it correctly.

Step Description
1 Prepare the sheathing by ensuring it"s clean and dry.
2 Lay down the first sheet of ondulin at the roof"s edge, aligning it properly.
3 Fix the sheet with ondulin nails at every wave crest along the edges and every second crest in the middle.
4 Overlap the next sheet over the previous one by at least one wave.
5 Continue fixing the sheets in the same manner until the roof is covered.
6 Check all nails to ensure they are secure and properly driven in.

The process of attaching ondulin to the sheathing is simple and can be completed with the appropriate equipment and methods. Make sure your sheathing is clean and firmly fastened before you start.

Using special ondulin nails, fasten the sheets by overlapping each row as you work your way up from the bottom edge of the roof. To guarantee a long-lasting and weather-resistant finish, make sure you adhere to the manufacturer’s instructions regarding nail placement and spacing. This technique gives your house a fashionable touch while simultaneously shielding your roof from the weather.

Brief information about the lathing

If you are doing all of your own construction work without a professional’s assistance, you should pay close attention to the sheathing. The following are essential guidelines that you should follow when building a roof:

  • In the case when the angle of inclination of the roof fluctuates within 5-10 degrees, the sheathing is made solid. Suitable for this boards or plywood. The magnitude of the longitudinal overlap should be at least 30 cm, while the side one will be equal to the width at least two waves slate sheet.
  • If the roof slope is 10-15 degrees, the sheathing is made of durable boards, which are attached to the joists every 45 cm from each other. The longitudinal overlap can be a maximum of 20 cm, and the width of the side overlap can be equal to the size of one wave.
  • When the roof slope exceeds 15 degrees, ondulin is placed on a crate made of boards, the distance between which should not be less than 60 cm. The longitudinal overlap in this case will only reach 17 cm, and the lateral overlap will be the width of one wave.
  • In order for the roof to subsequently turn out to be of high quality, you should immediately think about the correct arrangement of bars or boards in the sheathing. Install them clearly parallel to the edge of the roof, while taking constant measurements between all components of the sheathing.
  • A little ahead of time, we’ll answer a question that interests many: is it possible to fasten ondulin with roofing screws?? No, you can"t, no.To. self-tapping screws do not provide complete waterproofing of the hole.

What is ondulin, advantages and disadvantages

A relatively new roofing material that has gained a lot of traction is called Ondulin.

The following list of benefits of this material explains this:

  • Is environmentally friendly material, since it is made from mineral fillers and cellulose fiber, which are impregnated with bitumen and special resin at the final stages.
  • Due to free coloring, may be different colors.
  • Due to the fact that ondulin is produced in two types: slate and tile, this allows it to be used to create roofs of various configurations and complexities, which significantly reduces material and physical costs.
  • Possesses light weight, making it easy to lift onto tall buildings.
  • Resists the effects of heavy precipitation and mechanical damage thanks to good strength indicators.
  • Long shelf life (can reach 50 years).
  • Relatively low cost.
  • Does not deform and does not change its technical characteristics under the influence of temperature fluctuations, as well as large amounts of moisture.
  • In the process of fading or erasing the factory paint, the outside can be painted in any other color you like.
  • Able to resist exposure to chemicals.
  • Easy to saw and lay, which greatly simplifies the installation process.
  • It is a fairly plastic material, which allows bend it in any direction.

Ondulin’s propensity for spontaneous combustion is its sole significant disadvantage. During the production process, this material is treated with specific substances to reduce its flammability percentage, thereby making it safer for human consumption. In addition, ondulin’s service life is noticeably less than that of materials like metal tiles or corrugated sheets.

It’s important to remember that a roof made of this material could have several drawbacks if any of its parts are installed improperly.

How to fasten ondulin – with self-tapping screws or nails

How is ondulin fastened to the roof? Ondulin is secured with nails. They ought to be positioned as follows: in the crest of the wave, in overlaps, and on the sheet’s edges. The material must be penetrated by the nails only vertically.

Use regular rope that is pre-tensioned parallel to the building’s walls to prevent misdirected sheets.

How many nails should be prepared for each sheet of ondulin is a common question. The answer is that each sheet of material needs twenty nails.

To install the ridge, align it with the outer edge of the waves and fasten it firmly to the sheathing bars using nails. It’s also important to remember to make an ondulin apron that will sit between the wall and the roof, with an extra layer of waterproofing layered underneath. Nails are also used to secure it.

Use nails as well if you intend to install a small skylight to let more natural light into the attic. Verify that there are no openings anywhere that might let water in.

How should self-tapping screws be used to secure ondulin? It is not advisable to use self-tapping screws when installing ondulin roofing for the following reasons:

Attaching ondulin to the sheathing with self-tapping screws is not the ideal solution. Should you still choose to attach ondulin with their assistance, it is preferable to place rubber washers underneath them as well, as this will give you more, albeit incomplete, tightness. For this reason, using ondulin nails for fastenings is still preferable.

Calculation of the roof on the roof

Accurately calculating the number of sheets needed for a given roof is not at all difficult when one is aware of the standard size of one ondulin sheet. Thus, a single sheet measures 950 by 2000 mm.

To begin with, you must determine the area of the roof as well as its length and width. Next, determine how many sheets—along with the size of the overlap between the sheets—will be required to construct a specific roof using basic mathematical formulas. Let’s get right to the point now: installing ondulin on your roof yourself. Use our online calculator to determine the amount of ondulin quickly and simply.

Do-it-yourself ondulin installation

When placing ondulin yourself, you should follow basic guidelines and recommendations to ensure that all of the work is done accurately and to a very high standard. How to affix ondulin correctly:

  1. Make a sheathing from bars, nailing them to the rafters. Do not forget to take into account the slope of the roof and therefore the pitch of the sheathing under the ondulin.
  2. If you immediately need to cut a sheet of material, use an electric or regular saw.
  3. Place sheets of this roofing material so that they lie in the opposite direction from the wind (here you should take into account in which direction the wind most often blows in a particular area).
  4. You need to begin work on fastening the sheets down up.
  5. It is recommended to use nails for installation. There should be at least 20 of them per sheet.

Use stretched cord or rope to complete this step of the project quickly and artistically. Nails should then be driven along this cord for all ensuing sheets.

  • How to nail ondulin correctly? The scheme is quite simple. Nail carefully on each wave on both sides, at the end of the sheet and in overlaps. To increase strength, a nail is driven into the middle of each wave (or at least through one wave), making sure to hit the block.
  • Attached to the cornice board drain.
  • A ventilation comb is installed under the edge of the ondulin, which will prevent insects from entering the roof.
  • Nail the ridge to each sheet of ondulin and an additional batten of sheathing.
  • Cover the roof ribs with special ondulin elements, which, due to their flexibility, can take on any shape.
  • Glue the joints of the roof and walls with special insulating tapes.
  • Nail the apron in the area of ​​connection between the roof and the vertical wall, additionally laying waterproofing underneath.
  • If desired, you can install a fan or window on the roof.
