Many New England homeowners wait until water is dripping through the ceiling before calling a roofer—but by then, the damage is already done. Your roof will usually give off warning signs well before it fails completely. The key is knowing what to look for.
Here are 10 signs your roof needs repair—before it turns into a full-blown (and costly) replacement.
- Missing or Damaged Shingles
Shingles are your roof's first line of defense against the elements. If you spot areas where shingles are:
- Missing entirely
- Cracked or curling at the edges
- Torn off after a windstorm
- Covered in bare patches (no granules)
…it’s time to call a pro. Missing shingles expose the underlayment and decking, making your home vulnerable to leaks
Don’t wait for a leak. Here are 10 warning signs your roof needs repair—especially if you live in Massachusetts or anywhere in New England.
- Water Stains on Ceilings or Walls
Yellow or brown stains on interior ceilings or walls usually indicate a roof leak. Even if the water hasn’t made it to the floor, it’s already soaked insulation, wood framing, or drywall.
Leaks often appear far from the actual source due to water migration, so a full roof inspection is needed to trace the problem.
- Moss, Algae, or Lichen Growth
That green stuff on your shingles isn't just cosmetic—it’s a sign of moisture retention. Moss can lift shingles, while algae and lichen accelerate shingle decay.
In Massachusetts’ humid climate, especially in shaded areas, this is a common issue. Professional roof cleaning can stop the damage early and restore your roof’s appearance.
- Granules in the Gutters
Asphalt shingles naturally lose granules over time, but if you’re finding large amounts in your gutters or at the base of your downspouts, your shingles may be deteriorating faster than expected.
Granule loss reduces UV protection and speeds up aging—especially after a hailstorm or high heat summer.
- Sagging or Uneven Roof Lines
Your roof should appear straight and level. A sagging area could signal:
- Rotten decking
- Damaged rafters or trusses
- Prolonged water intrusion
- Structural compromise from ice dams
Sagging is serious—schedule an inspection immediately.
- Flashing Damage
Flashing is the metal barrier around chimneys, skylights, and vents. If it’s bent, rusted, cracked, or missing sealant, water can slip through the seams.
