Check These Places First For Roof Leaks
Some parts of the roof are more prone to leaks than others. Here are such parts and why you should focus on them while hunting for a leak on your roofing:
The Roof Vents
The roof vents are the openings through which air gets into the attic and stale air gets out of the house. The vents also provide the atmospheric pressure necessary for the proper functioning of plumbing fixtures. However, these vents can also cause roof leaks if they are damaged or if the connections between them and the roof aren't watertight.
The Roof Valleys
The roof valleys are the V-shaped junctions between two adjacent slopes of a roof. The roof valleys are common points of roof leakage because all the dirt and water on the roof end up in the valleys. This means the valleys experience more wear and tear than other parts of the house, which means they are also more likely to develop holes.
Roof flashing is a material, typically metal, used to seal joints between different sections of the roof. For example, when you install a chimney on the roof, a flashing material is used between the chimney and the surrounding roof. Being a joint, it makes sense that the flashing is more likely to develop water leak problems than other sections of the roof made of continuous materials.
The Ridge Cap
For a sloped roof, the ridge cap is the highest point of the roof. This is where the different sides of the roof meet. A complicated roof design is likely to have multiple ridge caps. In most cases, the ridge cap experiences considerable wear and tear due to foot traffic.
One of the reasons some people don't like skylights is that they are notoriously difficult to waterproof. This is particularly true of skylights installed by amateurs. In such cases, you will find that the skylight edge easily cracks or loses its waterproofing ability after a short while. However, professionally installed skylights don't have such problems.
Any roof projection increases the risk of water leaks because they interfere with the continuity of the roof. Not only that, but the holes punctured by the installers of these systems may also allow water to penetrate the roof. Therefore, in addition to all the above parts of the roof, you should also inspect the areas around roof installations while hunting for the source of a leak. For example, if you have communication gadgets on the roof or television antennas, you should inspect the areas around them for damages that may cause leaks.
