The roof is an essential part of any building. It keeps the elements out and helps keep the ac and heat within the building. However, over time, the roof needs replacement to avoid further problems with the structure caused by water leaks, rot and rodent intrusion. Here are the most common signs to look for on your roof.
If the roof is made of shingles, they are made to lay flat. Over time, the shingles can start curling. Clawing shingles sit flat on the edges while the middle moves up. Cupping shingles start curling upward at the edges. The extent of the curling can indicate how much time you have to call general contractors Halifax for a new roof quote.
The roof should never have a growth of moss or algae on it. However, that being said, don’t panic. The plant life can easily be washed away, but you can replace the shingles with algae-resistant ones if you don’t like the look any longer. Use a professional to clean the roof to avoid causing problems such as taking granules off the shingles.
Loose granules found in the gutters can indicate the shingles are breaking down. While a few granules may just be extra ones, having a bunch on a roof older than ten years may require replacement. The granules keep the shingles from baking which causes them to quickly deteriorate.
A sagging roof is a serious issue. The supportive system of the roof may be suffering which could lead to collapse. There is a variety of support structures that can fail. Localized sagging is easier to fix than waiting until there is a huge problem.
Seeing sunlight coming through the roof can indicate a problem. If sunlight can filter through, so can water. Sometimes small leaks only need a simple repair. Large leaks may result in roof replacement if not further repairs.
