Five Factors That Impact the Life of Your Roof

The roof on your home in Gig Harbor, Port Orchard, or Tacoma was a big investment. And whether it’s brand new or a few years old, let’s talk more about what impacts the lifespan of your roof.


The contractor you hire will have the biggest impact on how long your roof lasts. That’s why we are proud of the Rainy Day Difference. Our approach includes complimentary inspections and estimates and a lifetime warranty on workmanship. We are committed to being your go-to roofing contractor.

Improper installation includes not only poor workmanship, but also inadequate ventilation, poor materials, and bad weather conditions.

The Materials

A roof is expensive, but we have the knowledge and expertise to help you find the right roofing materials to fit your goals and your budget.

No matter your budget, it’s important to invest in quality to ensure your roof investment lasts as long as possible.

During our inspection and estimate, we will take the time to listen to your goals and will detail all your options.

Proper Ventilation

Proper ventilation is a crucial part of your roof. In your attic, you likely have intake vents that are located along with the soffits, and exhaust vents that are located at the peak of your roof. These two components work together to keep the air circulating throughout the space.

Proper ventilation ensures that any excess heat and moisture is not an issue in your home. Heat and moisture buildup cause problems like mold, deterioration of your insulation, and issues with your roof and shingles.


Properly maintaining your roof plays an important role in how long your roof lasts. Whether it’s once or twice a year, maintaining your roof ensures you get the most out of your roof.

We recommend clearing debris off your roof, clearing your gutters and downspouts, and checking your shingles for damage. Get the full maintenance checklist in this blog post: Spring Roof Maintenance Checklist.


In the Pacific Northwest, it’s easy to assume that rain is a roof’s biggest culprit. However, the sun and wind put your roof at risk too.

The rain usually becomes a problem after ongoing, consistent rain because it can easily pool on rooftops or will settle in any moss or tree branches left on your roof. The moss then acts like a sponge and holds the water on your roof for a prolonged period.

Sunlight exposes your roof to ultraviolet rays, and long-term exposure to sun and UV rays can cause shingles to become brittle and crack. In the Pacific Northwest, this typically happens to roofs that are 15-20 years old.

Strong winds can be very damaging to homes, and it doesn’t have to be a hurricane for the wind to cause damage to your roof.

During a windstorm, gusts of wind or sustained wind will loosen or lift your shingles. This can cause large patches of the roof to be exposed, or it can leave your shingles cracked.

After a windstorm, wait for the storm to pass and be sure your roof is safe to access. Then do a visual inspection, and if you notice missing or cracked shingles, get them replaced immediately. Replacing shingles is something you can do yourself, but the important thing is to protect your roof before any real damage is done.

If your roof is nearing the end of its lifespan, give us a call. We provide free inspections and estimates and work with you to determine the best next steps.
