Inspection and assessment of the condition of the roof
First you need to climb into the attic and find out the condition of the rafters, the laid floor and the waterproofing layer. It is necessary to check if it is pulling from there with dampness, if mold has appeared. If the tree is severely faded or covered with dark spots, this may be due to constant moisture.
Damp walls and ceilings in the rooms of the house can be signs of worn roofing. But in some cases, the roof may not be to blame for this. Sometimes it’s all about leaking pipes (water supply, sewage or heating). There are often cases when water flows along the outer wall, and then enters the house through the interfloor joint.
An internal inspection of the roof is best done during heavy rain, in which case it is possible to more accurately determine the locations and causes of leaks.
One of the signs of a roof leak, in this case, not only the rafter legs are damaged, but also the roof lathing.

Then they gradually go down to the valleys – perhaps they are full of branches and leaves that need to be removed and only after that you can view the element.

The most common roofing diseases
Most often, the roof leaks due to the following reasons:
#1. Violations of the integrity of the roof.
# 2. The joints of the roof covering with walls and vertical elements such as antennas, pipes and parapets can be depressurized.
# 3. Another common problem is the breakdown or failure of the drainage system.
All of the above problems arise for the following reasons:
- If the fasteners and roofing material are of questionable quality, then they will not last long.
- In addition, violations of technology are possible during the installation of the roof. This creates excessive loads that destroy the roof.
- If snow or ice is inaccurately removed from the roof and gutter, they can be damaged, after which they will begin to collapse.
- Moss and fungi that have settled on the roof also spoil it and in some cases this process of destruction can occur much faster than you might think. To prevent this, it is necessary to timely carry out maintenance of the roof.
- Destruction from time to time – even a very high-quality roof and a well-built roof, after lying on the roof for a long time, wears out, requiring replacement or repair.
As you can see, everything is pretty simple in theory. But in real life, it is not always possible to find a leak in order to repair the roof of a house. Sometimes water drops fall inside the house when the wind blows from the side, driving rain or snow under the roof. It often happens that dripping from the ceiling is not at all where water enters the interior of the house. In such cases, it is better if the roof and the entire “roofing pie” are checked by professionals.
Repair of the truss system
The entire the roof repair san antonio tx rests on the rafter legs, they take on the load from the weight of the snow, rain streams and gusts of wind, and of course the weight of the roofing material itself. And if the rafters are damaged, then you should not hesitate. The problem needs to be addressed immediately.
In the damaged place, the sheathing, insulation and roofing are removed, the crate is disassembled. If the rafter support is rotten, they clean the affected area well. Then the boards are stuffed from two sides of 80-100 centimeters long and 3-5 centimeters thick. They are fastened with long nails. It also happens that a piece of rafters rots to the very core. Then it needs to be cut out and a bar prosthesis installed, 2 or 2.5 times longer than the rotten part of the rafters. Overlays are placed on its edges. The whole structure is connected with nails 10 or 15 centimeters long. While work is underway, temporary racks are substituted under the rafters, but after the bar prosthesis is installed, they are removed.
Two ways to repair rafter legs.There is another option – the rafters are intact, but the crate is damaged and it is no longer under the gravity of the roof. We eliminate cracks and deflections by replacing the lathing or reinforcing it. To do this, a timber is laid between the rafters and boards are stuffed in the transverse direction.
Advice:
#1. Burn all diseased parts of the rafters after removing them.
# 2. Coat the cleaned areas with an antiseptic.
