Why Does Your Roof Only Leak After Some Rainstorms?

Posted on: 8 May 2017

Does your roof leak during some rainstorms, but keep your home perfectly dry during others? This can seem rather questionable and curious to homeowners, and it may even have you questioning your sanity! But the truth is, this is a rather common problem. The leaks occur when the wind-driven rain heads in a certain direction. Otherwise, when rain is just coming down or being blown in the opposite direction, the attic stays dry.

Here's a closer look at the issue of wind-driven rain and roof leaks.

What causes this type of leak?

Usually, leaks that occur sporadically happen because a few shingles somewhere on the roof are peeling up on one side. They may be peeling at the bottom, causing leaks only when the rain is blow up underneath them. They may be peeling to the right side, causing leaks only when the wind blows towards the left.

How can you find the peeling shingles?

In some cases, you may be able to locate which shingles are peeling just by looking up at your roof from the ground. Try to position your head so you're looking straight towards the roof. Do you see an area where the shingles look raised or uneven? This is where the leak is coming in.

If your house is tall or your roof has a complex design, you may need to climb up on a ladder and look at the roof more closely. Try to view it from a few different angles; this makes you less likely to overlook the peeling shingle edges.

How can you fix the problem?

If you feel comfortable climbing on the roof, this is an issue you can remedy on your own. You'll need roofing cement, some roofing nails, and a hammer. Start by placing a dab of roofing cement under the edge of the peeling shingle. Then, drive a nail through the peeling edge. Pound it down so that the head of the nail is flush with the roof, and then apply another dab of cement over the head of the nail. Repeat this process for every peeling shingle. You may need to use two nails along the edges of some of them if they are peeling badly.

If the shingles are peeling so badly that they are barely attached, or if they seem to be losing granules, your best bet is to call a roofing contractor. They can replace the damaged shingles so that wind-driven rain no longer seeps through your roof during storms. For more information, contact companies like Todd Harkleroad Roofing Inc.
