7 Signs You Need a New Roof
Recognize the warning signs that indicate your roof may need replacement before problems become emergencies.
Your roof doesn't fail overnight. There are warning signs that indicate when replacement is approaching. Here are the 7 most important signs to watch for.
1. Age of Your Roof
Most roofing materials have expected lifespans:
- 3-Tab Shingles: 15-20 years
- Architectural Shingles: 25-30 years
- Metal Roofing: 40-70 years
- Slate/Tile: 50-100 years
If your roof is approaching these ages, start planning for replacement.
2. Curling or Buckling Shingles
Shingles that curl at the edges or buckle in the middle indicate:
- Moisture in the attic
- Poor ventilation
- Age-related deterioration
- Improper installation
This is a sign replacement is needed within 1-5 years.
3. Missing Granules
Those granules on shingles protect against UV rays. Signs of granule loss:
- Granules in gutters
- Bald spots on shingles
- Uneven color across roof
- Exposed asphalt showing
4. Daylight Through Roof Boards
If you see light coming through your attic:
- There are holes or gaps in the roof
- Water is likely getting in too
- Structural integrity may be compromised
This requires immediate attention.
5. Sagging Areas
A sagging roof indicates:
- Structural damage
- Water damage to decking
- Failing support systems
- Excessive weight (snow/ice buildup)
This is a serious issue requiring prompt replacement.
6. Recurring Leaks
If you're constantly fixing leaks:
- The roof membrane is compromised
- Flashing has failed
- Materials have reached end-of-life
- Repairs are no longer cost-effective
7. Moss and Algae Growth
While moss looks concerning, it's often treatable. However:
- Extensive growth indicates moisture retention
- Can lift shingles and create gaps
- May indicate ventilation problems
- Requires professional assessment
Common Questions
How can I check my roof age if I didn't buy it new?
Check home improvement records, ask previous owners, or have a professional estimate based on material condition and style.
Are dark streaks on my roof a problem?
Dark streaks are usually algae growth. While unsightly, they don't necessarily indicate roof failure. Cleaning can help, but severe cases may indicate moisture issues.
Should I inspect my own roof?
You can observe from the ground using binoculars, but we don't recommend climbing on the roof. Schedule a professional inspection for thorough assessment.
