How can you tell it’s time to replace your roof? The best ways are by keeping track of your roof’s lifespan and keeping an eye out for the warning signs of roofing damage. 

Time for a Roof Replacement

What’s the Average Lifespan of a Conventional Roofing System? 

It depends on several factors, such as the kind of material used, the quality of workmanship and the frequency of maintenance. For instance, asphalt shingles – the most popular roofing material in the country – usually last 20 years. 

Important note: the quality of the shingles can also affect your roof’s lifespan. That’s why it’s best to stick to reputable brands like GAF. Remember: cutting corners on the quality of roofing materials almost always ends up costing homeowners more in the long run.  

The Warning Signs of a Failing Asphalt Roof

What are the warning signs you need to keep an eye out for? 

  • Granules in your gutters – The granules embedded in asphalt shingles protect your roof from ultraviolet (UV) rays. It’s natural for asphalt shingles to lose granules over time. However, as your roof ages, the degree of granule loss increases. If you start to see bald patches on your roof or notice granules in your gutters, you should start planning a roof replacement. Without these granules, your roof is vulnerable to UV-induced premature aging. 
  • Curling shingles – Curling shingles are usually caused by wear and tear, but they can also be a sign your roof doesn’t have enough ventilation. Without adequate ventilation, moisture will reach the base of the shingles, causing the shingles’ edges to curl. 

How much ventilation does your roof need? In general, there should be a square foot of net free area (NFA) (the area through which air can pass) for every 300 square feet of floor area for attics with a vapor barrier. And, if your attic doesn’t have a vapor barrier, there should be a square foot of NFA for every 150 square feet of attic floor space.

If you’re not sure whether your roof should be replaced, it’s best to consult an experienced contractor.
