6 Reasons For Roof Failure: Why Doing It To Code Isn’t Enough

June 9, 2022

Before You Have That New Roof Installed, Consider These
Reasons For Early Failure

A roof replacement is a huge investment that you don’t want to waste. Making sure it’s installed up to code is a major part of the project. But did you know there’s more to it than that? There are six major reasons why roofs in Seattle fail. The good news is that you can prepare and prevent these failures from happening.

1. Lack Of Ventilation And Trapped Air

When there’s no real ventilation, heat and moisture can build up in the attic and roof assembly. Your attic should never be too warm or too moist, so you’ll need balanced ventilation during the summer and winter months.

Water retention can cause damage to the structure of the roof. Even with barriers and shingles, you can have excess water retention from the moist air underneath it all. Did you know this water can even cause your roof to rot from underneath and even allow harmful mold to build up?

To avoid these problems, you’ll want to make sure you choose ventilation for your roof that doesn’t just “check a box” but one that does the job you need: ensuring proper air movement throughout the roof system.

2. Use Of Low-Quality Roofing Materials

You might be tempted to save a few dollars by buying cheaper materials for your roof. Before you do this, you’ll want to make sure they’re going to do the job for you.

Cheaper materials might seem cost-effective at the time of your roof replacement but they have the potential to fail quickly after protecting your home for only a short period. Are you a house flipper, planning to dump the property on some unsuspecting new homeowner? That’s one type of customer. Or are you keeping the place for a while? If so, going cheap might save money at the start, but choosing cheap may end up costing you a lot more in the long run when you go through an early roof failure and have to replace the roof again in a very short period of time.

That’s why the average life of a Seattle roof is just 17 years!

3. Flashing Failure

Flashing is what protects the most vulnerable sections of your roof from water infiltration and is made of plastic or metal. It can be found near all the roof penetrations on your roof valleys.

If these important parts of the roof are not installed, gaps will be left unsealed in your roof’s structure, and water will be able to sneak in and damage your roof.

4. Faulty Installation

Not choosing the right contractor for your roof replacement can result in a roof failure, because short-cuts are all too common. If they do not do the installation correctly, you can be left with leaks, moisture damage, and structural rot. Remember, just because the contractor cuts you a deal doesn’t mean it’s the best choice. Cheaper isn’t always smarter.

5. Roof Traffic

If you have a lot of people, like cable contractors, on your roof, this can speed up the failure of your roof. You will want to limit the amount of traffic on your roof to prolong its lifespan. As an alternative, you can get walkways installed during your roof replacement to limit the amount of walking on your roof. This is an advantage to some asphalt shingles that come embedded with copper granules: it cuts down the algae and moss growth. Similarly for metal roofs, very little maintenance is required.

6. Extreme Weather

Harsh weather is simply unavoidable. In Seattle, we experience a lot of rain and snow. To combat this factor, you’ll want to make sure you’ve installed the top roofing materials to stand up to the weather, and that you’ve chosen the best contractor in town who knows exactly what you need for the rough weather.
