A roof replacement might become inevitable when the roof outlives its life. It might be necessary to replace roofs even in the absence of any visible signs when the roof reaches the end of its life. Knowing the longevity of your roof will help to know if it is time for a replacement. 20-30 years is the recommended life for asphalt roofs, and 40-50 years is the lasting time for metal roofs, while slate and concrete roofs can last for a century or more. Since most households install asphalt roofs because of affordability and decent longevity, staying prepared for roof replacement after 25 years seems sensible.
It is possible to extend the roof longevity with proper maintenance because the most damage happens during the rainy season when a lot of debris collects on the roof, and the chances of water accumulation from clogged drains are high. But still, roof replacement would become unavoidable at some point in time either a few years earlier or later than the recommended life.
Here are the signs that tell you it is time for replacing the roof
When the roof leaks, the signs of water seepage will show up on the ceiling just under the roof. Cracks around the flashing increase the chances of leakage, and the valley that directs rainwater to the gutters are also vulnerable to leaks. A few leaky spots are manageable, but roof replacement is inevitable if there are too many.
Light seen through the roof boards
No light should pass through the roof, which is a sign of good roof health. However, if you see some faint rays of light visible from the underside of the roof or ceiling by going up to the attic, it is a sign of serious damage which calls for immediate roof replacement. Contact some roofing companies Gainesville FL and undertake roof inspection to evaluate the extent of damage before taking a final call. Roof replacement is an expensive project, and you must put up some inconvenience.
Missing, curling, or buckling shingles
Shingles undergo maximum damage to sun exposure, and with time it tends to buckle and curl, especially in the sloped areas of the roof. Curled or bent shingles at the slopes are beyond repair, and replacing the roof is the only option, which is also the case if there are too many damaged shingles across the roof. While you can manage to replace a few missing shingles, if there are too many, which occurs frequently, it indicates the weakness of the roofing system when replacing the entire roof is necessary. Repairing is effective only when the damage is less, and the roof system remains unaffected. But when the damage is extensive, repairs will not work.
It is important to evaluate the extent of damage and its impact on the building before deciding the course of action because all damages might not be as bad as it might appear, which only roofing experts can tell. However, if you observe roof sagging, it is a sure sign of the end of life of the roof.
