As we all know roof trusses are pre-engineered from the truss manufacturer according to the specifications that was specified by the blue-print. Framers will install all the roof trusses one by one and then sheet the whole roof with plywood. Shingles and ventilation will be installed according to the builders specifications and now we have a brand new roof.

Your attic is full of insulation and its job to keep the house warm and don’t allow any heat loss through your attic. During hot summer days your attic might get extremely hot and if the roof vents are not installed minimum 8 feet apart or there isn’t enough roof vents exhausting the attic air, it will cause the hot moist air to get trapped in your attic because of the lack of ventilation. Time being it gets so hot in your attic all the 2×4’s that is used to build your roof trusses gets twisted and they crack in the middle or became lose. Once the first 2×4 moves or shifts, it causes rest of the structure to lose stability. Plywood that is nailed on to that 2×4 caves in and problem became bigger. Also if this problem is not noticed heavy snow loads park on the roof for months also makes things worst and even cause leakage. Most of the time these problems get noticed, when the house is in the market and a good inspector actually notices it. Or next rain fall water starts to come in and when the roofing company arrives for the repairs. These types of problems are dangerous when it doesn’t get noticed and becomes a bigger issue down the road.
