There’s a lot that goes into a roof, and likewise, a lot that goes into a leak repair. We try to answer some of the most common questions surrounding leaks.
What does a roof leak look like?
There are several signs of a roof leak, but one of the most common is a stain on your ceiling. If you notice any discoloration or damp spots, there is almost certainly a leak to blame. From there, you can investigate the source.
Also, if you notice your walls are bulging or have concentrated moisture, there may be a leak as well. And gutters can leak too - make sure water isn’t dripping and that it is moving away from the roof, as designed.
How do I know where the leak is coming from?
The first thing you should do is note the leak’s location on your ceiling and take a look from the outside. If any foreign objects on your roof or shingles are missing, it is likely the culprit for a leak.
If it’s not apparent, you could take a hose to the roof and spray around the affected area. Have someone on the inside who can see if a leak resumes. From there, you can try to pinpoint where the leak is.
You should also check your attic to see if there are any openings or damaged connections to the main roof. If you see or smell mold, make sure to take care of it right away. If you don’t have access to an attic because you live in a rental property, connect with your landlord to make sure the issue is addressed.
How do I fix a roof leak?
While a severe leak will need to be looked at by a professional, there are things you can do to mitigate damage from a leak coming from your roof.
If you notice misplaced or curled shingles, grab some asphalt roofing cement and apply a generous amount to the underside of the shingle. Then press it down back in place and make sure all edges are sealed. And always replace a damaged or missing shingle.
Will my roof leak if I have missing shingles?
It depends. It certainly poses a greater risk of leaking when a shingle or multiple shingles are missing. One damaged or missing shingle can create a chain reaction, with others deteriorating around it.
While not an emergency, you should look to repair the shingle as soon as possible. Exposing the decking or other roof elements to the outside can increase the likelihood of damage or leaks. When replacing shingles, make sure it is the same material as the rest of your roof.
Can a roof leak cause mold?
Yes. There are different ways mold can manifest following a roof leak. If the attic has proper ventilation, mold will generally only form around the leak point. If there is poor ventilation, mold can grow and spread throughout the area, causing significant damage that a professional needs to address.
Mold and mildew can even penetrate your HVAC system and other parts of the home. As condensation builds, there is more likelihood of mold growth.
Not only does mold impact your home, but it is also a hazard to your health.
Who should I call for a roof leak?
Any time you find a leak coming from your roof, you should call your local roofing company. These experts can help diagnose and repair any problem that may arise. Also, a leak may be more complicated than it seems. A professional roofer can make sure all loose ends are tied up, reducing the risk of further damage. Likewise, many DIY remedies are not effective or can even make things worse.
