7 Reasons Why Your Roof Leaks

Recurring roof leaks are frustrating because the cause isn't always apparent. Even small leaks can destroy property and possessions, so you shouldn't ignore a leaking roof. Explore the top causes of recurring roof leaks below.

1. Missing or Broken Shingles

If your area with strong winds, check your roof frequently for missing shingles. Often, winds rip off shingles in places you can't see, leaving you to wonder about the cause of roof leaks. Don't ignore broken shingles either, as water squeezes through the tiniest cracks. Your roofer matches replacement shingles by color and manufacturer to prevent further water damage.

2. Damaged Flashing

Flashing is a piece of metal that directs water away from roofing joints and seams. Roofers install flashing around skylights, chimneys, dormers, and under shingles to prevent water from entering through cracks on your roof.

Over time, rain and wind erode the tar roofers use to seal the flashing, allowing water to seep through your roof. The flashing sections can also move out of place because of missing nails. Damaged flashing can be hard to spot if flashing is concealed, so have a roofer inspect the roof if you can't identify the source of roof leaks.

3. Poorly Sealed Vents

Expert roofing installation is vital because poorly sealed penetrations like vents let water through the roof and into your home. Roof vents look like pipes sticking out of your roof and discharge moisture from your home's interior.

Roofers install a rubber boot around the place where the vents stick from the roof, but the materials comprising the boot break down over time. Leaks around the vents appear dark and emit a musty smell. Your roofer replaces the boot with longer-lasting materials to discourage leaks.

4. Shallow Roof Slope

Roofers must install your roof to the correct pitch to facilitate water flow to the gutters. A double layer of underlayment may also be necessary as additional protection against water. Consult professionals if you want a flat roof because water can accumulate in the roof's low spots and cause roof leaks.

5. Blocked Gutters

Gutters direct water away from your roof, but they must be clog-free to do the job correctly. If left unattended, gutters gather leaves, twigs, and other debris, which block the water flow. Since rainwater pools for a long time in clogged gutters, it is more likely to seep through any cracks or weigh down the gutter system.

Clogged gutters are easy to notice, especially if you often inspect your roof. The lack of water gushing out of the downspout when it rains also indicates blocked gutters.

6. Ice Dam Buildup

An ice dam forms when ice builds up on a roof's edge and prevents melting snow from draining correctly. As a result, water sits on the roof's surface and seeps through any existing opening, while the weight of the ice adds extra pressure on the roof. If the gutter or other components break from this strain, water can leak into the house and cause extensive damage.

7. Incorrectly Installed Skylights

Skylights are exciting home additions as they allow natural light in and enhance ventilation. Skylight installation requires a large section of your roof to be cut, and the contractor must flash and seal the sides of the skylights.

Over time, the insulation around skylights deteriorates, lets water in, and leaves you placing buckets to catch dripping water. A roofer will repair the flashing or insulation and prevent leaks.
