What are the signs my roof needs replacement?
One set of questions Above Roofing and Exteriors customer service reps hear is similar to this:
- How many years should a roof last?
- How do I tell when it’s time to replace roofing?
- What are the first parts of a roof to “go bad” and start to leak?
Not too long ago shingle manufacturers gave a number for how many years their roof was good for. Just like tires, though, this had mostly to do with how long the manufacturer was willing to warranty their shingles, and, just like tires, warranties were pro-rated, so that you might have warranty left, but it didn’t carry much value, and it is hard to prove that what you have is “normal wear and tear.” In the past decade most major shingle manufacturers are using the term “lifetime” shingles, and a customer can choose (and purchase) the kind of warranty they want. It is possible to purchase, with a new roof, a 50-year, full-replacement warranty. Manufacturers generally figure their asphalt shingles will last about 25-35 years. They are willing to offer a warranty good for longer than the “normal life” of the shingle because chances are you’ll sell your home before the warranty is over, so they won’t have to pay for your new roof.
But the 25-35 year lifetime is for a roof under good conditions. Negative factors like poor ventilation (see previous blogs) can severely shorten the life of asphalt shingles. If ventilation is poor, the attic can get very hot and the shingles “cook” on the roof. This often shows up as curled shingles.
Shingles that are very badly cracked and curled are so possibly because of poor ventilation.
Maybe the most common sign of “natural aging” on a roof is granule loss. Due to heat, weather and age the asphalt holding the granules on the shingles’ surface deteriorates, and the granules come free and slide down the roof.
Because of loss of granules on the gray shingles, one can see the substrate (base) of the shingle. The sun shining on this part of the shingle causes faster-than-normal deterioration. It’s time to replace this roof!
Another symptom of shingles that are advanced in age and deterioration are cracks in the shingles. The shaded picture features one of the symptoms of shingle age, cracks throughout.
