The final stage of construction work was and remains the installation of the roof - video instructions, which can be found in abundance on the Internet, will help you not only determine the sequence of work, but also understand a number of nuances. And so that the entire roofing installation algorithm is clear, we suggest that you read the instructions below.
Roof frame
Roof installation begins with the construction of its frame. As a frame for most roofing systems, rafters are used - special structures made of wood, metal profiles or reinforced concrete beams, on which the roof itself rests.
For small private houses, as well as if you are building a roof yourself, the best option for a truss system is to use wood.
Boards and bars of various sizes (their thickness is determined by calculation), it is preferable to use coniferous ones, and those from which the resin has not been previously lowered - it will act as a preservative and antiseptic.
Note! Before installing on the roof, all parts of the rafters must be treated with an antiseptic (prevents damp wood from rotting) and a fire retardant
We install the rafters with the lower ends on the Mauerlat - a wooden bar firmly fixed around the perimeter of the house. We connect the upper ends of the rafters with a ridge beam. If the length of the rafter run is more than 6 m, we additionally strengthen the frame with braces (horizontal bars connecting the rafters under the ridge) and racks.
To fix the rafters, we use staples, steel brackets and self-tapping screws. We connect thicker rafters with each other in pairs of studs with a diameter of 8-12 mm to avoid displacement.
The technology for erecting rafters is shown in sufficient detail in the video instructions, so it is quite possible to learn this on your own.
After the rafters are erected, you can start laying insulation and waterproofing material.
Roof insulation and waterproofing
The next stage of roofing work is roof insulation. We lay sheets of insulation between the rafters and fix them on a counter-lattice - a grid of wooden beams stuffed on the rafters.
On the inside of the insulated roof, we must fix a vapor-permeable film - it will prevent condensation from forming, and as a result, moistening of the insulation.
We lay a layer of waterproofing directly under the roofing material, which is designed to prevent leakage even in the event of damage or defective roofing.
We fix vapor barrier materials directly to the rafters. For fixing, we use galvanized nails or a construction stapler with galvanized staples.
crate
For laying roofing material on the rafters, a so-called crate is needed - a system of wooden beams that will serve as a support for the roof elements.
There are two types of crates - sparse and solid.
- sparse roof lathing made of wooden boards or beams, which are stuffed directly onto the rafters. The pitch of the lathing is determined by the dimensions of the roofing materials.
- A solid crate is erected from edged or tongue-and-groove boards, as well as from moisture-resistant plywood or oriented strand board.
Sometimes a combined crate is used: a classic sparse crate is made on the slopes, and in “problem” places - on skates, in valleys and along the edges of the slopes - solid.
Laying roofing material
The final stage of work on the construction of the roof is the laying of roofing material.
As a roof for the roofs of private houses can be used:
- Standard slate roof - the simplest and most economical type of roofing material. For fixing, special slate nails with linings are used.
- Metal roof and tiles - very different, ranging from classic ceramic to modern metal tiles.The method of fixing it largely depends on the type of tile, so when you know what exactly you have to cover the roof with, choose a video instruction specifically for this material.
- Soft roofing materials are represented by bituminous tiles and roofing tiles. These materials are mounted with an adhesive layer, and for additional fixation they are attached to the crate with roofing nails.
Summarizing, it can be noted that self-installation of the roof is quite possible. Moreover, today you can find enough information (both in traditional text and in video format) to come to work fully armed!
