10 Common Causes of Roof Leaks and How to Fix Them

Posted by Northface Construction  - Owner & Founder

There are few things more annoying than a leaky roof, and unless you want to break out the drip bucket every time you get some rain, you’re going to want to fix the leak.

To help you out with those frustrating leaks, we’ve made a list of the 10 most common causes for roof leaks and advice for how to fix them.

Old Age

Sometimes the issue is as simple as your roof just being too old. Over time, roofing materials will become less effective when it comes to keeping water out of your home. If this is in fact the issue, it’s time to contact a roofing contractor to help get some new material for your roof to make it work like new once more.

Roof Vent Damage

If you have venting on your roof, check out the area of your roof surrounding the vent and see if it is dark or damp. This is a tell-tale sign that your venting is the issue. You can typically solve this problem by sliding a new rubber “‘boot” under the vent.

Valleys Aren’t Properly Sealed

The valley of your roof is the area where two planes of the roof meet. Because of the sloped nature of these valleys, if they are damaged or not properly constructed, rain running down the valley will likely trickle into your home. In terms of fixing this issue, a professional will likely be needed, where they will address the issue by laying a new leak barrier along the valley and shingling overtop.

Debris Buildup

If there was a recent storm and you haven’t had the chance to clean any branches, twigs or leafs off your roof, the debris can build up water and trap it against the roof, making it more likely to slip through any small cracks in your roof. The solution for this one is simple, which is to clean your roof when it gets filled with too much debris. Just make sure that you are taking the necessary safety precautions when you’re on your roof.

Flashing Needs Replacement

Flashing is placed where the roof joins a dormer, and where the chimney attaches to the roof. Flashing sections may slide out of place if nails are missing and caulk can also dry and crack from the wear and tear of weather. Similar to the vent problem, you can solve flashing issue by swapping old material out for newer ones.

Ridge Cap Leaks

The opposite of your valley is the ridge, which is the peak where two panels meet. If this is the issue, a contractor will likely have to be called because when it comes to ridge cap leaks, usually the problem occurred during construction of the roof.

Gutter Backup

Just like with debris trapping water in the valleys of your roof, gutters can also get clogged by leaves and twigs.Gutters that are clogged will giving water time to soak through the roof. Once again, make sure that you clean your roof often and see if that does the trick for your pesky leak. Gutter covers can help keep gutters clear of debris.

Untreated Holes

While this may be an obvious one to avoid, sometimes holes left from T.V. antennas or similar objects can be the problem. Make sure that if you are ever having something removed from your roof that the area is properly sealed.

Ice Dam Buildup

When ice forms at the edge of a roof and therefore prevents melting snow from running off, you have an ice dam. If it’s winter and you’re getting leaks, you should act fast because the weight of the ice itself can cause damage to the roof.

The best option for you in this case is to buy a roof rake that can be used to remove snow from your roof. If the ice won’t budge, you may need to treat it with an ice melting product to loosen it.snow and ice damage on roof

Condensation in Your Attic

A leak is most likely coming from your attic if the space shows signs of mold growth or mildew. A strong, musty odor  emanating from the attic is also a key that water has gotten inside.

If you find mold or mildew near the leak, then it may be coming from your attic. This means that there is too much condensation build up above you. To treat the issue, get rid of the mold growth. Make sure that your attic is then isolated to prevent changes in temperature and install a ventilation fan as well.
