A healthy roof is necessary to protect you, your family, and your assets. Routine care and maintenance can prevent a whole host of emergencies, but even the best-cared-for roof ages and needs replacement eventually. Here are 3 signs it may be time to replace your asphalt shingle roof:
It’s Reaching the End of Its Life Span
When was your roof built or last repaired? Experts agree that an asphalt shingle roof’s lifetime is between 20 and 25 years. Anything beyond that is susceptible to major damage and is due for a replacement. If your roof is more commonly exposed to harsher weather conditions such as hurricanes, tropical storms, blizzards, or ice, that may significantly reduce the lifespan of your roof.
If you’re unsure of the age of your roof, hire a roof inspector or professional roofing contractor. A good inspector will come fully licensed and certified to help identify the age of your roof using technically refined skills from years of experience. Bringing in an expert often is the best way to know when it’s time to replace your roof.
You See Worn, Broken, or Missing Shingles
Evaluating the health of your shingles is important to understanding how effective your roof is. Shingles are specifically designed to withstand and endure the inclement weather conditions your home faces. They help protect your roof by carrying run-off rainwater and snowmelt away from your roof to keep your underlayer, decking, and rafters dry.
Over time, these shingles wear down. They can show signs of buckling when the roof sheathing moves beneath the shingles due to moisture exposure in the attic. If your attic does not have proper ventilation, moisture can build up in the heat, causing shingles to warp and curl as well. You’ll want to take a hard look at your shingles to check for signs of buckling, curling, or warping in addition to falling apart or even missing shingles.
Be sure to also check your roof valleys for damaged or missing shingles. This area endures the most wear and tear since it collects rainwater and snowfall throughout the year and carries it down to your gutters. If your shingles show signs of these poor conditions, your roof is at risk of major water damage.
You Find Mold or Mildew in the Attic
For a closer look, take a walk upstairs to your attic to inspect the insulation and plywood surfaces for signs of water damage. You may find light or dark colored mold or mildew lurking behind your insulation and on the surfaces of your roof framing and sheathing. Further inspect your trusses for wood rot with a moisture meter that measures elevated moisture content in water stains. Your attic is the perfect place to check for signs of water stains, leaks, or other damage, since it will be the first place on the interior of your home to be impacted by a poor roof.
This is also the time to look for proper insulation and ventilation set-ups. If your attic does not have proper ventilation, warm air rises in your home and gets trapped in the attic. The warm air then condenses, providing yet another opportunity for water to damage your roofing structures. If you see natural light showing through or sagging roof decking inside the attic, it may be time to replace your asphalt shingle roof.
