If one thing is for sure it is that roof lines should always be straight. If you see any dips or curves on the peak when standing from a far- - we hate to be the bearer of bad news but, your roof has a problem. It might be a basic issue or you might need a professional; let’s find out.
Pay close attention to any signs of sagging even if the symptoms are not noticeable at all. Look at the exterior of the property and the interior as well- - when in the interior, check for cracks on the ceiling’s drywall.
When weight accumulates on the roof, it causes pressure and the hangers will pull loose from the beam as the exterior walls pull outward. Because of this, the result will be a sagging roof. When rafter ties are not properly installed, sagging roofs also occur.
You must pay close attention to the beam as well- - is it adequately nailed A poorly nailed beam will definitely cause your roof to sag. Another common problem that will make a sagging roof occur is if the beam is the wrong size or if it has any cracks or splits.
In some rare cases, sagging roofs don’t always have to mean that you have an issue with your home framing. Roofs will also sag when you have rotten or saturated sheathing. If a rotten sheath is the problem, the good news is that this problem is actually the easiest to resolve. Sometimes sagging roofs originate from poor installation of shingles- - and when water penetrates the shingles the sagging begins.
Remember, all sagging roofs issues should be handled by professionals at all times. A professional has the training and capacity to evaluate your saggy roof and then they will develop the proper procedure on how to go about repairs. The extent of repairs can be a bit difficult to figure out but a professional will ensure that your roof is repaired the right way.
