Sag In My Roof

Two or more roofs on one structure spell trouble.

Sag in my roof.

If the sagging roof is due to rotting or warping roof decking the repair will be much easier. If the framing is. The home may not be designed to support the weight of this extra roofing material and it will sag. Additionally if your roofer has used material that is much heavier than your previous roof it can sag for the same reason.

This may be problematic in winter months but allowing the roof to continue to sag can lead to greater problems such as a cave in. Once you have established how much the roof sag needs to be jacked up lay a 2x4 plate across the ceiling joists and nail directly under the ridge of the roof. Sagging or low spots in a flat roof may be due to undersized or weakened roof joists or problems with the buildup layers beneath the exposed roofing. You will need to remove the shingles and the old decking however which means there will be an exposed hole in the roof.

A sagging roof is not only an eyesore but it could also be dangerous for you and your family. In cold winter climates snow is the most common cause of excess weight on the roof. Since roofs are designed to be straight a curved or sagging roof means that its structural integrity is insufficient and it may be a warning sign that your roof is headed for collapse. In some cases roof sagging problems are not caused by framing issues.

If you have just stepped outside your house and realized that your roof is no longer straight this could signal a problem. Now add collar ties from one side of the rafter to the other. Every roof is designed to support a specific maximum weight and anything above this especially for long periods can cause the roof to sag. Why roofs sag as mentioned roofs sag because there s too much weight or load for the existing structure.

Non foundational reasons for a sagging roof. If you notice that there is a visible dip in your roof chances are you have a problem with one or several rafters and you may soon be facing more issues like water leaks bowed out walls or your roof caving in on you. Fixing a sagging roof as soon as you spot it is very important otherwise you could find that the problem will only worsen over time and in the end you may need to have the entire roof replaced which could be extremely costly not to mention a lot of hassle. If these already exist nail a 2x4 to them directly under the 2x4 plate you nailed down before.
