Is it time to replace your roof?
Roofs aren’t designed to last forever. As one of the most important layers of protection for a home, you don’t want to rely on an unreliable roof. Knowing when to replace your roof depends on how long you’ve had it and whether it’s been repaired. You can’t just tell if your roof needs replacing by a glance. There are protective elements that can wear away without too many visible signs. Here’s the average lifespan of the most common roofing types.
Roof lifespan by material:
• Wood Shingle Roofs: 30 Years on Average
• Metal Roofs: 40 – 50 Years for Tin; 60+ Years for Steel
• Foam: 50 Years
• Shingle Roof: 20 Years
• Clay Tiles: 100 Years
Is a longer lifespan better?
The answer to this question isn’t cut and dried. Cost has to be measured in, and certain roofs are much more difficult and expensive to repair. Clay tiles last very long time for instance, but they are extremely heavy, require extra anchoring, and can be costly to repair. You’ll want to speak to your roofing contractor about which roof meets your needs and budget.
What are the most common signs of roofing damage?
Missing or damaged shingles. These can often be seen from the ground. Shingles are supported by a protective moisture barrier and in the case of asphalt shingles, the water-resistant properties of asphalt and tar. Even a single damaged shingle can leave your roof exposed to the elements. If you notice these issues in multiple places, it’s time to get a new roof before you experience greater damage.
Leaks, buckling, and water stains.
Water damage is a major indicator of a roof failure. You won’t always see signs of damage outside either. Many signs occur indoors, and you may see stained ceiling tiles, mold or water spots in the attic, or worse, a stream of water. A lower level leak may also be caused by plumbing, so make sure you know what’s wrong and have it fixed. Water will destroy a home from the outside in and inside out.
Check your gutters.
Your gutters collect heavier materials. Because chips, cracks, and shingle wear can wash into your gutters, it’s the perfect place to check for granules. Many homeowners have their roofs inspected after severe weather. In the Northwest, this typically occurs during the Fall and Winter Windstorm season. Anyone who’s lived in the area for a few winters will be well-versed with the local news Storm Alert.
If your roof is at the end of its lifespan, you’re likely due for a replacement soon. What’s the best way to know for sure, though? A roof inspection. Until you’ve had your roof inspected by a professional, the best you can do is make an educated guess.
