When Do You Need Roof Replacement In San Mateo?

Roof leaks are terrible. Not only do they disrupt the day to day lifestyle of the residents, but they are also a significant safety hazard. If you have a leaky roof, you should get in touch with an experienced contractor for a roof replacement in San Mateo. But why do roofs leak? Discussed below are some of the most common causes -

Poorly Sealed Valleys

Valleys are regions where two planes of the roof are conjoined. The valleys often are not properly sealed since they are usually placed in a sloping design. Improper sealing of these valleys could cause rainwater to enter the roofing structure. Check for damp spots that run along the joints of your roof. If there are any leaks, it is probably because the sealing has been cracked because of external causes (someone has applied force to one of the planes or due to excess rain). A Roof replacement professional in San Mateo will be able to fix these seals. A new leak barrier needs to be applied along the valley.

Cracked Vent Booting

Roof vents are the tiny pipes that stick out of roofs. They are used to eject excess moisture. If these regions of your roof start leaking, your roof will get dark spots, and over time, the roof can rot due to the constant exposure to moisture. Roof vents can be easily sealed. Use a penknife to detach the rubber around the vents. Use pry bars to break the seals connecting other shingles. Slip the new rubber boot underneath the shingles and stretch it to the top of the vent. Then, fetch it down against the roof. After that, tighten the new boot with roofing nails on each side or seal underneath the shingles to attach them to the new flashings.

Roofing Nails Getting Exposed

Roofing nails can often get exposed. This exposure causes small holes to appear. From these holes, rainwater can easily seep in. The damage is even worse when the backed out nails are close to the edge of the roof since wind-driven rainwater can enter. These small holes are typically imperceptible to the inexperienced eye. Hence, most homeowners don't even know that their roof is damaged. In the long-term, these little holes can multiply and cause massive damages. It is advisable to have your roofs checked or of the leaks are too big, get a Roof replacement in San Mateo.
