Your roof is one of the most important parts of your home as it protects you from the elements, insulates your space, and helps maintain your home’s structural integrity. But over time, even the most durable roofs begin to wear down. Knowing the signs that your roof needs to be replaced can help you avoid costly damage and ensure your home stays safe and secure. Xpert Xterior would like to walk you through the key indicators that it’s time for a roof replacement, and why acting quickly can save you money and stress.
Your Roof Is Over 20 to 25 Years Old
Most asphalt shingle roofs last between 20 to 25 years, depending on the quality of materials and whether the roof was properly ventilated and maintained. Signs of an aging roof:
• Worn or brittle shingles
• Frequent repairs
• Granule loss and fading
If your roof is approaching or past this age range, it may be time to consider a replacement even if there are no obvious leaks yet.
Shingles Are Curling, Cracked, or Missing
Damaged shingles are one of the most obvious visual signs that your roof is failing. What to look for:
• Curling: edges turn upward or cupping downward
• Cracking: caused by weather exposure or aging
• Bald spots: where shingles have lost granules
• Missing shingles: often after a windstorm
These issues can allow water to penetrate your roof, leading to leaks, mold, and wood rot.
Roof Leaks and Interior Water Damage
Water stains on your ceiling, attic insulation, or walls can indicate that water is getting through your roof. Common causes:
• Worn-out shingles or underlayment
• Cracked flashing around vents, chimneys, or skylights
• Ice dams forcing water under shingles in winter
If leaks are happening in multiple areas or return after patching, it could be a sign that the entire roof system is compromised.
Sagging Roof Deck or Uneven Rooflines
A sagging or drooping roof is a major red flag. It often means there is trapped moisture, rot, or structural weakness in the underlying deck or rafters. What to check:
• Dip in the ridge line
• Uneven slopes or waves on the roof surface
• Soft or spongy spots when walking on the roof
This issue requires immediate attention and usually warrants a full replacement.
Excessive Moss or Algae Growth
While moss and algae may seem like just a cosmetic issue, they can trap moisture and cause shingle damage over time. Signs of trouble:
• Thick patches of moss
• Dark streaks or stains
• Shingles lifting or separating in mossy areas
Cleaning may help temporarily, but if growth is widespread and persistent, it can be a sign your shingles are no longer performing properly.
Granules in Gutters or Downspouts
Granules help protect asphalt shingles from UV rays and weather. As shingles wear out, they shed granules, which often collect in gutters. What this means:
• If you see a large amount of granules in your gutters or near downspouts, your shingles are likely nearing the end of their life.
• Bald shingles without granules are vulnerable to cracking and water absorption.
Rising Energy Bills
A failing roof can impact your home’s ventilation and insulation, causing your HVAC system to work harder. Signs may include:
• Increased heating or cooling costs
• Drafts or inconsistent indoor temperatures
• Poor attic ventilation or moisture issues
Replacing your roof can improve energy efficiency and comfort inside your home.
Frequent Repairs or Persistent Issues
If you find yourself constantly patching leaks, replacing shingles, or addressing interior water damage, it may be more cost-effective to replace the entire roof rather than continue with short-term fixes.
