Crate for OSB on the roof

The selection of materials and construction techniques is essential for building a stable and long-lasting roof. The OSB (Oriented Strand Board) crate is a crucial part of contemporary roofing. This base structure serves as a solid foundation for the layers that follow, which is essential in supporting the roof covering.

A framework of wooden battens or beams positioned horizontally across the roof trusses makes up the OSB crate. In order to distribute the weight of the roof covering and any loads placed upon it equally, these battens are positioned strategically. Usually constructed from premium wood, like pine or spruce, these battens are chosen for their robustness and longevity.

The cost-effectiveness and structural integrity of OSB make it a great choice for the crate. OSB panels are engineered wood products made of adhesively bonded compressed wood strands. Because of its construction, OSB is very strong and resistant to shearing and bending forces, which makes it perfect for use in roofing applications.

Precise measurement and alignment are necessary during OSB crate installation in order to guarantee a level surface for the roof covering. In addition to improving the roof’s structural integrity, proper installation extends the roof’s life and functionality. The OSB panels are firmly fixed to the battens, forming a strong base upon which the weight of the metal sheets or roof tiles can be supported.

How to make a crate under a soft tile on the roof – theory and practice

A crate is used to secure any kind of roofing material to the roof. What it is going to be is dependent upon the coating type. We will discuss what should be a crate beneath a soft tile in this material, as well as the proper way to fix it.

The crate is essentially a collection of rails or other materials fastened to the rafter system in preparation for the finish coating to be applied later.

The main nuances and the scheme of the crate

There are two possible crate schemes for flexible tiles:

• with gaps – for the installation of hard coatings, for example, metal tiles, slate or corrugated board;
• laid down with a continuous layer – for the flooring of a soft roof.

It’s important to note that a continuous crate installation for soft roofing requires two layers. A continuous layer of the crate from a continuous OSB of the plate under a soft roof or plywood with a moisture-repellent impregnation is already attached to the rafters after a rail or board is first filled on top of the rafters with gaps. Additionally, this finish layer provides thermal and acoustic insulation.

The installation technology of the crate and the OSB for soft tiles

The following guidelines should be followed when installing the crate, just like they should with all other roof structural components:

1. A continuous coating of a board or sheet of moisture-resistant plywood is made on the pitched roofs with a slope between 5-10º.
2. On the slopes, the slope of which is 10-15º, first the crate is made under the OSB on the roof of the bars with a section of 45 × 50 mm, laying them in a pitch of 45 cm parallel to the cornice, and then the waterproof plywood or a chip plate is laid.
3. The same beam is also used on roofs with a slope of more than 15º, however, they are laid 60 cm from each other.
4. Additional bars are installed in places where Endova is attached to the ridge gear.

If you place the soft roof on precisely sized boards, it is thought that the roof will last the longest. This will result in an even crate with no height drops, allowing you to precisely fit the joints. As a result, under such circumstances, the coating will not suffer premature damage or lose its functional properties.

Trimmed conifers are the best choice for construction because they combine good operational qualities with a low cost.

The boards are laid with an indentation of no more than 10 cm when assembling a sparse crate for the later installation of a soft roofing. Wood-bearing plates, a trimming board, and moisture-resistant plywood sheets are effective materials for continuous crate construction. Please take note that the OSP installation under a soft roof needs to be done on sturdy boards, and that the humidity level shouldn’t go above 20%.

The crate needs to be sturdy enough to endure the following since it will be subjected to outside forces:

• increased snow loads in the winter;
• The mass of the finish coating.

The computation of the roof’s structural components is done in light of these circumstances. Specifically, the crate is constructed from 10 mm waterproof plywood or 20 mm smallboard if the step of the rafters beneath the soft roof is 50 cm. A board 30 mm thick or 20 mm thick plywood is used when the rafters’ pitch is increased to 120 cm. In other words, the distance between the rafters directly affects how thick the OSB is for the soft roof.

Please be aware that wood is far more prone to rot and fungal growth than soft tiles. Consequently, all wooden components should be treated with an antiseptic prior to installation.

Why do you need a dropper on a roof

One of the crate’s required parts is the dropper. Its job is to keep water from flowing over the cornice. This is significant because wooden structures are more likely to rot in these areas. The dropper’s inner angle may vary by 100 to 130 degrees, contingent upon the steepness of the incline. Because these components are fixed to the roof’s edges, water is guaranteed to drain precisely vertically and into the drain. The dropper also gives the roofing a more polished appearance overall.

• such parts are made from galvanized sheet steel with a polymer coating that provides additional anti -corrosion protection;
• The color scheme of the dropper should coincide with the color of the main coating so as not to create dissonance;
• The droppers must be installed around the entire perimeter of the roof in order to equally protect the roof and facade from the flow of water;
• This element reduces the sailing of the pitched roof, this allows you to protect the structure from the wind.

The method of installing the dropper

The following subtleties are present in the dropper installation technology:

• The main part of the dropper is fixed on the board of the crate, while its lower segment should be directed to the drain;
• The neighboring segments of steel droppers are laid with overlap on each other;
• Additional protection of the edge of the crate is provided by front -line strips;
• At the next stage, the installation of a roofing carpet begins, not forgetting to smear its edges with mastic, so that it grabs better;
• Soft roofing is covered on top of the dropper.

Recommendations on the thickness of the material and the step of the crate

Thus, the crate is a crucial component that enables you to apply a soft roof coating in a high-quality manner.

The following are general suggestions for its installation:

1. For a soft roof, two layers of crate are needed, combined into a single design.
2. The surface of the continuous crate should not contain changes in height and defects.
3. In order to avoid damage to the soft coating, all protruding sharp ribs and bends must be rounded.
4. As a rule, a trimming board with a width of 14 cm is used.
5. So that moisture does not leak into the space under the roof, the board should be laid upward.
6. As well as sharp ribs, the ends of the extreme boards must be rounded so as not to damage the roofing material.
7. The protection of wood from pests and decay will ensure antiseptics processing.
8. The power of the wind in a particular region, as well as the slope of the pitched roof, affect the step of the crate under the soft tile. With an increase in wind strength, the distance between the board decreases.
9. Moisture -resistant sheets of plywood or chip plate under a soft roof should be laid with an indent of 1 cm so that when the material is swelling from moisture, it does not crack.
10. The dropper will allow you to protect wooden cornices and a crate from the flow of precipitation.
