7 Signs You Need a New Roof in Cambridge

1. Curling, cupping, or clawing shingles

Asphalt shingles that lift at the edges or buckle in the middle have lost their flexibility. In Ontario's freeze-thaw cycle, that means water gets underneath on the next ice storm. A few curled shingles can be replaced; widespread curling means the roof is at end of life.

2. Granules in your eavestroughs

Those black sand-like grains protect the asphalt from UV. Once they're washing into your gutters in handfuls, the underlying mat starts cracking within 1–2 winters. Cambridge homes built in the early 2000s are right in the danger zone.

3. Visible sagging or dips in the roofline

Stand across the street and sight along the ridge. Any dip, wave, or sag means the decking underneath is rotting or the trusses are stressed. This is urgent — call a roofer this week, not next month.

4. Daylight through the attic

Head up with a flashlight off. Any pinpricks of daylight through the decking means active water entry. Look for dark streaks on the rafters and damp insulation.

5. Shingles missing after a Cambridge windstorm

Our spring and fall storms regularly hit 90+ km/h gusts. Three or more missing tabs in one area, or any exposed underlayment, qualifies as storm damage — and is usually covered by home insurance.

6. Ceiling stains or peeling paint upstairs

Brown rings on a bedroom ceiling almost always trace back to either roof penetrations (vents, chimney) or ice dam backup. Either way, the roof is involved.

7. Your neighbours are all replacing theirs

Cambridge subdivisions were built in waves. If three or four houses on your street have new shingles, yours is the same age — and your insurer knows it.
