Preventing Roof Leaks
Water entering your home is the most visible symptom of a leaking roof. However, you can detect a leak until it becomes visible. Water is creeping in if there are brown, discoloured patches on the drywall ceiling. Water leakage can rot the roof framing structure, undermining its structural integrity and necessitating substantial and costly repairs even if there are no visible signs of a leak.

Inspection as a preventative measure
As a result, it’s best to try to avoid leaks with routine roof inspections – at least twice a year, as the National Roofing Contractors Association recommends (NRCA). Since the winter is the most difficult season for a roof, it is best to conduct inspections once in the fall and once in the late spring. As a means of soliciting work, several roofing contractors will include a free roof inspection, as well as a written estimate detailing the necessary repairs.
Take prompt action if you notice a leak, as a leaking roof can cause serious damage to insulation, walls, ceilings, flooring, and personal belongings. Larger leaks would certainly cause more harm, but even a small leak will cause enough damage to necessitate ceiling replacement.
Next, look for blinking.
The flashing around the chimney, vents, fans, and skylights, as well as lining roof valleys and eaves, are the most common causes of roof leakage. Exposure to the elements and UV rays causes the asphalt paste or caulking material used for flashing – or the rubber used to cover pipes and other protrusions – to dry out. The seal cracks or loosens when the materials dry out, allowing water to get in.
The good news is that these types of issues can normally be repaired for a reasonable price using asphalt cement, with a three-year lifespan. You may also replace the blinking, which should last for at least ten years. Leaks can also be caused by rusted and corroded flashing. They can be washed and repainted with rust-resistant paint to extend their service life, but badly degraded flashing and vents should be replaced.
Roofing shingles that have been worn out should be replaced.
Another cause of a leaking roof is advanced age. Asphalt shingles must be replaced when they curl, crack, or tear, or when the mineral granules wear away, exposing the black asphalt underneath. A repair job would suffice if just a few shingles are damaged. However, if one out of every five or ten shingles shows signs of wear, the roof may need to be replaced.
Roof leaks can be caused by minor cuts and tears in asphalt shingles caused by blowing tree limbs and debris. Single shingles are relatively simple to repair or replace, and can be done by a handyman or a roofing contractor. To avoid roof damage, keep tree branches at least 8 inches away from the building.
