Asphalt shingles are the most commonly used roofing material. Asphalt shingles are versatile and easy to install. You can expect asphalt shingles to last about 20 years, but there are factors that can shorten the life span. A roof that isn't installed properly can leak almost immediately, even though the roof itself is new. If the roof is exposed to harsh sunlight for the majority of the day, the asphalt is going to break down faster. Temperature extremes can cause asphalt to deteriorate, as can rain and extreme weather. Your roof can become damaged from high winds, or sustain impacts from falling branches. While a repair may work in the short term, eventually there are reasons to replace your existing roof with a new one.
Your Shingles Are Faded
While shingles will start to fade over time, this does not mean you have to replace your roof just yet. If you haven't had any serious leaks, you won't need a new roof for a while. Faded shingles are only the first indication that your shingles are starting to get worn by the sun. If you start to have leaks, a repair can be enough to fix the problem for now.
You Have Systemic Leaks
Your asphalt shingles might look alright from the ground, but systemic leaks are a sign that your roof needs to be replaced. Damaged shingles are not always obvious from your vantage point. If you have more than one leak, your roofing services may suggest a new roof. If you already have water damage in your home because of leaks in your roof, it's time to invest in a new roof to stop further damage in your home.
Your Shingles Are Curling
Asphalt shingles can curl up as they get old and deteriorate. You might see an area where a few shingles are curling, or you might notice curling shingles throughout your roof. Once this occurs, your shingles can't protect your home from the elements. Your shingles need to be replaced in order to keep your home safe.
Your asphalt shingle roof might have only one layer of shingles on it. If this is the case, a new layer can be added to the existing one to give you a new roof without having to remove the old one. This saves you money and keeps your home protected. When you have leaks or your shingles are in bad shape, it's time to talk to your roofing services.
