Have you ever wondered why all the commercial buildings have flat roofs? The answer is easy; an average home is very small when you compare it to a flat roof, it is possible to fabricate custom roof trusses for a house but when it comes to a flat roof it is impossible. Flat roofs are designed with steel frames and support beams and the houses are made out of 2×4’s and osb/chipboards.    When the flat roofs are being constructed the builder can install drainage or scuppers to get rid of the water. Some flat roofs are designed with slope so water will always drain on its own.
There are many different types of flat roofing system that require gluing, steaming, mopping or torching. If the existing roof was tar and gravel and now it is being converted to a torch-down roofing system, the slope, drainage or scuppers must be installed or addressed to eliminate water damage that could lead to a disaster. It is normal for a flat roof to have some water pooling but not a lot. During summer months water will evaporate eventually but if it rains again back to square one.
My personal recommendation would be to re-frame a new slope for water to run off or install drainage or install scuppers. To extend the life of your flat roof you must maintain it. Clean all the drain filters, remove all the leaves and debris away from the drainage and scuppers to get water moving, remove heavy wet snow to eliminate structural damage that can be fatal.

You may never find out if the trusses needs to be repaired unless it was pointed out to you by a home inspector if he/she really inspects the house or your roof looks bowed from outside and you have noticed it by yourself.

When providing an estimate for a customer, not too often but there are many times that I notice the sagging that was caused by broken roof truss. It becomes a conflict for me because it is not safe for me or my staff to be working on a roof that has possibility of caving in. Right away i document the problem with pictures from different angles to show it to the customer. Once the customer is aware of the problem i must inspect the attic visually and determine the exact cause and location of the problem.

It is a serious issue that may be caused by the heavy wet snow that was parked on the roof every winter, poor workmanship or bad material. It all depends on the size and shape of the house. The way it was constructed has a big part on how and why. Roof trussesare engineered and you

can’t buy them at Walmart. If there was an error during roof construction for example; too much pressure on one specific roof truss could cause it to snap, crack or crack in few years.

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.
