If the leak is not repaired immediately, it can cause severe damage to a house. It can be difficult to pinpoint the exact cause of a leak because water can spread outwards from the original site. Check your roof regularly for the common causes of leaks. This will help you to prevent future problems and stop any that are already present. Here are a few common causes.
Age
With age, roofing materials become less effective in keeping out water. Weather conditions and temperature fluctuations may cause roofing materials to crack and become brittle over time. The sun can melt the tar that holds the shingles on the roof.
Vents
To prevent leaks, you must seal all roof penetrations. Check for any cracks in the gasket that surrounds the vent pipe and for missing nails. Plastic ventilation can crack over time due to exposure to weather.
Slopes
If the slope is too shallow on the roof, wind can lift up the shingles allowing rain to get under. The slope of the roof is measured by inches, which is the ratio of the vertical rise to a horizontal distance of 12 inches. The Building Codes require that asphalt shingles have a slope of at least 2:12. Ensure that the roofing material you choose meets these requirements, and is installed correctly.
Debris
A buildup of debris on the roof, such as leaves, branches, and moss, can cause water to be trapped and seep into the walls. Maintaining a clean roof is essential to allowing water to drain effectively. For Roof Cleaning Cotswolds, contact www.gloucestershireexteriorcleaning.co.uk/roof-cleaning/cotswolds/
Flashing
Metal flashing is used to seal roof joints where water can accumulate or absorb. Flashing can be found at the junction of the roof with a dormer or around the edges of skylights. If a nail is absent, flashing pieces can be moved from their proper place. Caulk can also dry out and crack over time.
