The underlayment is the layer of the roof between the structure and the covering. It is formed by waterproofing and a grid of battens and counter-battens attached to the rafters, possibly boarding. The underlayment is responsible for the drainage to the outside of rainwater and water vapor, which managed to penetrate this zone. It is selected depending on the angle of the roof and the type of roofing material. It is to be the tighter, the less airtight the roofing is and the lower the slope. Nowadays, the waterproofing is most often a pre-covering film (with low or high vapor permeability - the latter are called roofing membranes), less often an underfelt (without sprinkling). Structural mats are laid under flat sheets, allowing condensation to drain from their lower surface.
Roofing material
Before making a decision, check the local zoning plan, or possibly the zoning decision. Local regulations may dictate not only the shape and pitch of the roof, but even its color.
It is worth taking into account the location of the house - by the sea the tin roof is more vulnerable to corrosion, under the trees moss and lichen will appear on the tiles. Where strong winds blow, it is better to choose small-format and heavy roofing.
Types of coverings
- Clay tiles - this is one of the longest used and most popular roofing materials. Manufactured from clay, they will easily last more than 100 years. To increase the resistance of the product to dirt deposition and lichen, the surface of the tiles is covered with a layer of noble clay (engobe) or glaze (glaze),
- Concrete tiles - also known as cement tiles - became widespread only in the second half of the last century. (ceramic ones have been known for thousands of years). Both types are laid in the same way, they also have very similar dimensions, weight and shape,
- Tile - is a sheet of metal stamped to look like a tile. Visually similar, it weighs 10 times less, instead of dozens - a few kilograms. The core of the material (0.4-0.5 mm thick) is usually steel sheet, less often lighter aluminum. It is covered with multilayer protective coatings that increase the product's resistance to corrosion, UV rays, scratches and damage,
- Flat sheet - today it is again fashionable coated like sheet metal, sold in sheets and as a panel product, has returned to favor. It is cut more easily than sheet metal, and the cut-off sections of the sheet can be used elsewhere. Flat sheets joined by craftsman's seam (as they were years ago) are laid on the boarding, finished seam panels (some say it's not seam, but click) are also laid on the grid,
- Asphalt shingles - are colorful strips of roofing felt cut to imitate the shape of traditional shingles. They are flexible, easy to cut, and great for finishing unusual surfaces. However, they require full boarding, often also roofing felt as an underlay (if the slope is less than 20°). Various types of sprinkles, mostly mineral, are placed on their surface. The color of the roof depends on them,
- Roofing paper - bituminous material coverings are airtight (of course, those made according to the art), lightweight, resistant to temperature changes and aging. Roofing paper has three layers, the most important of which is the load-bearing one - a warp of either veil or glass cloth, foil, or possibly polyester fleece. The type and thickness of the matrix soaked in bituminous mass determines how flexible and tensile the roofing paper is,
- EPDM roof membranes - are laid in a single layer. They come in rolls up to a dozen meters wide, so the entire roof can be covered with one sheet of material, without any joints! The membrane is durable (life span of about 50 years), strong, resistant to significant temperature differences and highly stretchable.
Grants
In the case of thermal modernization of the building, we can apply for funding from the Clean Air Program.
