Your roof not only improves your home's curb appeal, it also keeps you warm and protected from natural elements. For this reason, you should regularly inspect your roof to get ahead of any potential problems.
Sometimes, you may need to replace or repair damaged parts. However, even with repairs, some problems might become worse. In such a case, you'd need to tear down your old roof and replace it. Below are a few signs that it's time to replace your old roof.
Just like any other product, your roof will remain in good condition for only a limited time. Depending on your roofing material, your roof's average lifespan could be anywhere between 20 and 50 years. For instance, asphalt shingles can last for at least 20 years. Other materials such as concrete, copper, and slate could last more than 50 years.
If you've recently bought an older house, find out when its roof was last installed. Also, contact a certified roofing company to look for potential or existing problems. If a roof repair cannot solve the damage, your roofing contractor may suggest a complete roof replacement. But with repairable damage, they may recommend a shingles overlay procedure instead.
Curled or Missing Shingles
Roofing shingles often deteriorate with time due to constant exposure to harsh weather. Sometimes, you might even notice some missing shingles that leave behind patches you can't ignore.
Luckily, frequent roofing inspections can help you detect the signs of deterioration early. For example, asphalt shingles curl at the edges when they start to deteriorate. While one or two curled shingles may not be enough to worry you, several deteriorated shingles could be a good sign that you need to replace your roof.
With time, these curled shingles might become ineffective at protecting your home from rainwater or melted snow. Call a replacement contractor once you notice multiple leaks coming from your roof.
Oftentimes, mold creates an unsightly roof appearance. Mold also erodes your roof and weakens its structure. Worse still, mold can grow uncontrollably if you don't act quickly.
At first, you may notice the growth of mold spores between shingles and siding pieces. The mold can eventually move from your roof to the rest of your home. When mold spreads to your walls and ceiling, you and your family might start to experience severe health problems. Symptoms such as sneezing, coughing, and wheezing are more common with prolonged mold exposure.
Therefore, if your roof has widespread mold growth, consider tearing down your existing roof. The resulting structural damage might be too severe for any lasting repairs. But with a new roof, you can minimize the risk of mold growth to the rest of your home and ensure better reliability from your roof.
