Finding a leak in your roof is a challenge. Water likes to travel the path of least resistance. If you know how and where to look, you may be able to find the leaks on your own. However, you may still need roofing services to assist you in patching these areas to stop the leaks and prevent water damage.
Look for Loose Shingles
Loose shingles higher up on your roof can lead to leaks. As the water travels downward, it discovers that there is another path it can take and is diverted under the loose shingle. To find loose shingles, you need to very carefully get up on your roof and try to pick up individual shingle sheets. The shingles that are not loose will refuse to budge. The shingles that are loose will have no problem peeling up. There may even be plenty of moisture located under the loose shingles, which suggests that you have found the source of your leak.
Look for Flashing That Is Not Effectively Stuck
Tar and even metal panels are used for flashing. Flashing is the stuff that braces up the upper vertical walls of a house, off of a roof, or to the side of a chimney. Look for metal panels that are bent and not firmly flat against these vertical structures. Then look for any tar areas that have pulled away from these structures. These may also be areas where there is water leaking into your home. The metal panels have to be replaced, and the tar may need re-tarring.
Look for Damages or Unusual Areas That Look Wrong
Old roofs often have awkward areas that begin to rot and peel up. These awkward points in the roof are open channels for water to slink through. They will need to be nailed down and calked with a waterproof sealing caulk. Damaged areas that were created from large piles of snow, ice, and/or giant hail pellets also need to be checked and repaired. Even if water is not going into these damaged areas yet, it may eventually, and prevention is the best solution.
Look for Loose or Missing Downspouts
The primary purpose of downspouts is to prevent flooding and move water away from your roof and foundation. If downspouts are loose or missing, precipitation is getting past these areas and looking for the nearest inward route to the roof. Replace the downspouts and make sure they are secure to the gutters with duct tape or some other waterproof adhesive.
