cause of roof leaks and how to solve it

There are a few common causes of roof leaks that might happen to your house. In an effort to save you that investment, we’ve compiled a list of The 3 Most Common Causes of Roof Leaks. We’ll tell you what they look like, why they happen, and how to fix them.

1.   Your Gutters Are Clogged

What Does It Look Like: You may be able to see the leaves sticking out of the gutter when you look up onto your roof. But, if not, you should notice the lack of water trickling out of a downspout during a rainstorm.

Why It Happens: Your gutters are meant to help water travel away from the roof. When a blockage forms and they get clogged, that travel stops. Rainwater will then pool in one area of the roof and have more of an opportunity to seep through cracks.

How To Fix It: Many recommend placing a large tarp underneath the area where you are working. That way, you can drop any debris as you go and wrap it up for easy disposal later.

2. Your Flashing Has Cracked

What Does It Look Like: Flashing are thin pieces of metal that are installed under shingles and on the joints of your roof in order to create a water-resistant barrier, which can be concealed or exposed. If exposed, they will look like long runs of sheet metal and, if concealed, they will have a rubberized coating overtop. Broken flashing will feature large cracks

Why It Happens: Roofers often use tar to seal the flashing together and that can corrode over time. In the event that your flashing is left exposed, elements like wind and rain could be the reason behind its crack.

How To Fix It: (Via The Family Handyman): Once you locate the source of the leak, pry up the nails used to secure the old flashing. Lift any shingles out of the way and remove the cracked segment. Gently put a new run of flashing in its place, fasten the new flashing in the same pattern as your old piece using roofing nails. Then, apply a coat of roofing sealant to the nail heads.

3. You Have Broken Shingle

What Does It Look Like: Look up! This one is easy to spot. Since shingles are the exterior layer of a roof, you should be able to identify missing shingles by seeing different-colored patches on your roof. Alternatively, you may find the shingles themselves littering your yard after a heavy storm.

Why It Happens: Again, weather. High winds and heavy rains.

How To Fix It: (Via This Old House): Slide a pry bar underneath the row of nails that connects the damage shingle to the one below it. Lift up until the nail pops and then press down on the shingle while you remove the nail. Repeat for the remaining nails. Pull out the damaged shingle, replace it with a new one, and secure it with four new nails.
