If you've discovered you have a roof leak, the next step is to determine where the leak is located. That might not be as easy as it sounds since water can travel quite a distance before it drips down in your attic. Here are some areas where roof leaks are likely and how to determine if you need to repair your roof or replace it.
The first thing to look at is the condition of your shingles. If you see shingles missing or cracks in shingles, that could be the cause of the leak. Regular roof maintenance is needed to keep your shingles in good shape so that they don't leak. This might include sealing cracks or replacing damaged shingles. However, it's also possible your shingles could have widespread damage due to hail strikes, or your roof could be old and at the end of its life. If many of the shingles on your roof are damaged, then a roof replacement might be needed. If your shingles have storm damage, call a roofing contractor to take a look at your roof to determine if a new roof is needed.
The Roof Valleys
Rain that hits your roof rolls toward the valleys to drain to the gutters. This means the valleys get the most water and are more susceptible to leaking. There are two types of roof valleys: open and closed. If your roof has closed valleys, they will be covered in shingles. If the valleys are open, metal flashing is used instead. The metal may have corrosion damage or be loose and allowing rain to leak in. If shingles are in the valley instead, they may need to be replaced to repair the leaking. As long as the rest of your roof is in good condition, leaky valleys can be fixed with simple repairs unless water damage has occurred to the deck under the roof, in which case the deck will need repairs too.
Flashing And Rubber Boots
Anything that protrudes through your roof has to be sealed to keep rain out. That includes the vent pipe, attic vent, skylights, and a chimney. A vent pipe will probably have a rubber boot around it that keeps rain from rolling down the pipe. Rubber breaks down due to UV exposure over the years, and when that happens, water can leak through cracks and get in your attic. Flashing is made of metal, and it's applied around the base of a chimney or skylight. The metal might lift or shift and need to be reapplied. Metal might even rust and develop holes. Flashing should be checked for leaks when your roof is inspected because it is easy to replace the flashing and that could prevent water damage inside your home or on the roof deck.
