Roofing your home is one of life’s most important expenditures. Barring a catastrophic event, your shingles will most likely “age out.” Knowing when it’s time to replace your asphalt shingles is an important part of planning for a new roof. You can look for these signs that your shingles need to be replaced without climbing on the roof.
Composite shingles are made by soaking a fiberglass mat in asphalt or other waterproofing substance and coating it with reflective granules. As the shingles are exposed to the sun’s intense UV radiation, that waterproofing substance breaks down. The nature of shingles and the way that they are installed causes that process to be intensified at the shingles’ sides and edges. Over time, this uneven aging process will cause the shingles to crack, curl or cup.
Fortunately, this problem occurs gradually. At the first sign that your shingles are beginning to age out, have a professional roofer inspect your roof to estimate how long your roof has before it must be replaced. Note: cupped shingles hold water instead of shedding it and could encourage the formation of leaks.
The purpose of the reflective granules is to prevent the sun’s UV rays from damaging the shingles’ waterproofing substance, but over time, those granules fall off as the adhesive succumbs to the sun’s destructive energy. When this happens, you might notice what appears to be sand at the bottom of your downspouts. Hail damage can also cause granules to wash into the downspouts, so it’s important to call a reliable roofing Toronto contractor for an inspection at the first sign that the shingles are losing their protective covering.
Unless you inherited a transferrable lifetime roofing warranty, if it has been more than ten years since you bought your home, odds are that you will be needing a new roof soon. Most shingles are rated for 10 to 15 years, so have an inspector assess the condition of your roof to see how long it will be before the shingles wear out and need to be replaced.
Putting off the Inevitable
There is no getting out of replacing your roof, but there are things that you can do to maximize its serviceable life and to plan for the expense. Adhering to an annual maintenance schedule and performing proactive repairs can put off the need for a new roof for 2 to 5 years. Even if your roof is showing signs that it has outlived its warranty, asking roofers for estimates before a crisis occurs will help you plan for the expense ahead of time and eliminate some of the stress associated with a new roof.
