10 Most Common Causes Of Roof Leaks

Missing Or Damaged Shingles 

Broken shingles are one of the most common causes of roof leaks. Since this issue is immediately visible, it is easier to identify. When a strong storm hits with high winds you should take a look at your shingles to ensure they are still in good condition. 

Clogged Gutters

Cleaning out your gutters isn’t the most fun thing to do. To avoid further damage you must clean them. To make the job easier you can use a hose to flush the gunk out of your gutters. If your gutters are really dirty there are other tools you can use to help clean them.

Broken Flashing

Broken flashing could be the cause of your leaky roof. After a while, the tarring that holds your shingles together wears off. If a leak springs, check the flashing at the source of the leak. 

Attic Condensation

Attic condensation can sometimes appear to look like a roof leak when in fact 

Vent Boots

The vent boot could be a cause of your leaking roof. It is fabricated by rubber and slides over the plastic vent pipes, protruding from the roof. Vent boots can be metal, plastic, rubber, or any combination. When the gasket stops working, a new boot must replace it. Most of the time, calling a contractor isn’t necessary for this kind of repair.


Holes can develop in your roof without you knowing. Damage from storms can cause holes in your roof. Along with animals like squirrels and raccoons. This can be fixed by applying caulk around the hole and placing a small piece of flashing on top of it under the shingle. If you can’t do this call a professional roofer to inspect your roof and repair the hole.

Brick Chimneys

Brick chimneys may seem indestructible, but in reality, they aren’t. The mortar that keeps the bricks together is nothing but a mixture of sand, cement, and water. Weather elements cause this to erode quicker. Checking the mud cap on top of the chimney for deterioration is smart to do. Using patches are an easy, cheap way to repair this. 

Complex Roof Architecture

The design of your roof may be a real showstopper, but it can really be an invitation for disaster. Damage can be caused by not properly sealing the valleys and slopes on your roof.  Feel free to call Grace Roofing and Construction if you are in need of a leak barrier that still looks attractive. 


Skylights can instantly transform any interior space or room. Hopefully, you had yours installed properly. Leaks can sprout down the sides of poorly fitted skylights. Check for cracks around the flashing or loose shingles around the skylight. If you do discover these things you will need your skylight professionally repaired or replaced. 

If you are getting a temporary repair it will cost anywhere from $50 – $300 depending on how bad the leak is. The costs on average will be $300 – $1,000 to have your skylight re-flashed or re-shingled. Replacing a leaky skylight will cost on average $1,250 – $2,500.

Roof Age

One reason your roof is leaking could simply be the age of your roof. Roofing materials like asphalt shingles can get worn out a lot faster than others. Expansion and contraction from changes in temperature can cause your shingles to turn brittle or even crack. The sun gives off harsh rays that can cause the tar holding composition shingles together to melt away.
