Water and other moisture is one of the main culprits of roofing damage for your Seattle roof, so it’s one of the things you want to be particularly vigilant about preventing. Since the roof is a surface that sees its fair share of precipitation, it’s one of the most common places where moisture can make its way into your home, and that same moisture can also start to eat away at your roofing materials. Here are some of the dangers, and ways to avoid the biggest problems, when it comes to water on the roof.

Standing Water

Water that does not dry up or run off the roof is one of the biggest problems for your Seattle roofing. The longer it sits on your shingles, the more likely it will eat away at the asphalt on the exterior or find some other way inside to your attic, and eventually to your home’s interior. It’s important to regularly inspect the roofing to identify problem areas where water is still present in puddles more than a day or two after a storm. If you see it, call a Seattle roofing contractor to inspect it and make recommendations to fix the problem.

Clogged Gutters

The gutters sole purpose is to take the water, ice, and snow that hits your roof and channel it away from the house to a safe distance. Without working gutters, you run the risk of that water sticking around on the edge of the roofing, or overflowing and pooling up around your home’s foundation. Both of these situations can lead to significant damage, flooding, leaks, and more, so make sure your gutters are unclogged and free of debris before the next storm.

Mold, Mildew, and Algae Growth

In a climate like Seattle, where precipitation is a common occurrence, roofing has the additional risk of growing algae. When excess moisture is present on or below the roof, it can also create ideal conditions for mold and mildew growth. These things can damage your roofing shingles as well as the support structure in your attic that is holding the roof up, and should be addressed immediately. If your roof is in danger because of excessive moisture, find out more about how to fix the current problem and prevent that and other issues in the future by calling a Seattle roofing contractor today.
A roof replacement in Bellevue is no small undertaking, but it’s important to know when your current roof is showing some of the most common signs of wear and tear that would indicate that it has reached the end of its useful life. When that happens, homeowners should be prepared to hire a roofing contractor to replace their existing roof.

1: Your Roof is More Than 20 Years Old

The average lifespan of an asphalt roof is anywhere from 15 to 30 years, depending on factors like the climate, exposure to extreme weather, maintenance and upkeep. If your roof is on the latter end of that timeline and starting to show signs of damage, it might be time to replace it. If you have a roof layer that was installed on top of an existing layer, or your previous roofer in Bellevue didn’t properly ventilate the roofing, the lifespan might be even shorter.

2: Multiple Shingles Are Damaged

A few shingles that get damaged can easily be repaired, and often that won’t constitute the need for a full roof replacement, but if entire sections of your Bellevue roofing have damaged shingles—ones that are curling, cracked, buckling, or have lost most of their protective granules—chances are you will need to replace the entire roof. It should also go without saying that if you have huge sections of missing shingles, it might be better to replace than just repair.

3: Rusted Flashing

Metal flashing is installed around protrusions like your vents and chimneys to keep water from seeping in at these spots. Since this is where your roofing in Bellevue is most vulnerable, when flashing begins to rust or gets dented or damaged, it often leads to roof leaks.

4: Daylight Visible From the Attic

Homeowners often forget that they can check the health of the roof from inside the attic, and one of the most obvious ways to spot roof leaks and extensive damage is the presence of daylight shining through the roof into the attic. In some cases this can be repaired, but if the damage is extensive, chances are you’ll need to replace the roof. When you spot these signs, call a Bellevue roofing contractor to come and provide you with an estimate for roof replacement.
