Top 5 Most Common Roof Problems

Your roof will be in the best shape of its life during the first couple of years (assuming it was installed correctly), and will gradually become more needy after the first few years depending on how you maintain it.
Common Problems

Flawed Flashing

One of the single most common reasons why a roof leaks is due to improper flashing installation. Flashing is usually made of a metal or heavy rubber, and protects the roof where pipes and protrude. Because this is the only protection from your roof membrane, it’s crucial you take the time to install it properly.

Weak Flange

Another problem that tends to accompany flawed flashing is the weak flange. In most cases, the flange weathers and breaks down, revealing openings to your roof. This can result in leakage, so be sure to check and replace your flanges regularly. Some flange systems don’t require much work – simply slip the next and improved flange over your existing.

No Sealant

It’s crucial you seal any potential weaknesses in the roof, including where the flange fits around piping. Use a basic caulking to seal the potential weakness. This will close the weakness off from moisture, which in turn will protect your roof from leaks.

Bad Valleys

Roof valleys can be made of several materials, but provide the same function -- where ever you have two faces of the roof converging, you need to build in a valley in order to direct water off the roof swiftly. Valleys might be made of shingle or metal material depending on the style of the roof, your weather, and your preference. Improper installation of a valley can result in moisture build up and eventually leakage.

Missing Drip Edge

A drip edge is a small portion of shingle overhand designed to lead water away from the membrane of the roof, which protects the actual wood, so you could be looking at serious damage if you’re missing a drip edge and live in a regularly saturated area. It isn’t as common as others, but still poses a threat due to the damage it creates. The reason you need a drip edge is because of the capillary effect, which is the physical phenomenon of water flowing in opposition to gravity – more specially, what happens when water reaches an edge, curls over to the underside of the edge, and begins moving away from the edge. When this happens, water can saturate the membrane and eventually the wood beneath it. This creates extreme damage and leaks.
