Finding the source of a roof leak can be difficult if you don’t know where to start, especially when you consider that leaks rarely flow in a straight line. In this blog, Rogers Roofing shares a list of the places where roofing leaks are likely to develop.
- Roof Deck – There are many reasons the roof deck could develop leaks, from improper installation techniques to punctures caused by hailstones or airborne debris. One way you can easily tell is by climbing into the attic on a clear day. If you notice pinholes of light, then it’s very likely that you’ll have to deal with leaks the next time it rains.
- Roof Valleys – Roof valleys tend to be vulnerable to leaks because they are a break in the roofing plane, and rainwater tends to be funneled to these areas. This is why we can’t stress enough on how important roof flashing is. Check your roof, and make sure flashing is not displaced or missing.
- Roof Edge – The roof edge is vulnerable to wind damage, being exposed to both direct wind currents and updrafts. The first row of shingles should be intact, without gaps or breaks. Modern asphalt shingle roofing systems have a starter strip, basically a single strip of asphalt shingle that spans the length of the roof. Right under it is a type of flashing called drip edge, which should also be undamaged and in place. Clean gutters also help prevent rainwater from backing up into the roof and causing leaks.
- Chimneys, Vent Pipes and Skylights – These areas have one thing in common: they penetrate the roofing plane. Therefore, they need flashing at the point where their bases meet the roof. Chimney stacks and skylights typically have flat or step flashing while vent pipes typically have rubber or metal boots.
- Ridge Caps – Roof ridges are like reverse valleys. Instead of flashing, the peaks are capped using ridge cap shingles. Modern roofing systems feature ridge caps with vents for attic ventilation. If these vents and/or caps are damaged, leaks may form in these areas.
