Most homeowners don’t often check the roof of their home. A house’s roof is like the top of your head. You know it’s there and it’s important, but you don’t look at it closely unless you sense or observe a problem. Maybe you glance at your roof while pulling the car into the driveway or you inspect it after a storm.


Years pass until one day you’re forced to act after rainwater begins to drip from

the ceiling onto your electronics. To avoid emergency repairs (and new electronics), answer these questions to determine if you need residential re-roofing services.

How old is the roof?

A traditional asphalt 3-tab shingle roof lasts 20 to 25 years. If the roof has more than one layer of shingles and is older than 20 years, it may need to be replaced.

Are shingles curling or buckling?

If the shingles on the sloping, sunlit areas of the roof aren’t laying flat or appear to have lost texture, the shingles may need to be replaced.

Are roof valleys in good condition?

Channels along the ‘folds’ in your roof are more susceptible to wear and tear because they manage snow and rain into the house’s gutter system. Missing or damaged shingles in roof valleys can create leaks requiring roof repair or replacement.

Are any shingles missing?

Look beyond the roof valleys to see if any shingles are missing or have torn tabs. Although your roof has a layer of fiberglass paper under the shingles, it’s not strong enough to protect your home.

Do you notice granules from the shingles in gutters or near downspouts?

Shingles ‘shed’ their protective mineral granules over time, leaving bald spots on the roof and making your roof more vulnerable to sun damage and less fire resistant. If you notice granule build-up in your gutters or piled up near downspouts after a hard rain, or if you notice darker ‘bald’ spots on the roof, it’s time to call a roofing contractor.

Is paint near the roof line stained or peeling?

While the shingles may look intact, you may need roof leak repair if you see signs of water damage on the exterior of your house.

Do you see a leak (or daylight) in the attic?

If you’re able to get inside your attic, check for staining or moisture overhead or sagging roof boards. Another tell-tale sign it’s time for re-roofing services is daylight leaking into the attic. A weakened roof deck means the shingles aren’t providing adequate protection.

Is the chimney flashing intact?

Flashing is usually sheet metal installed around your house’s chimney, but it may also be cement or tar. Flashing is put in place to make the chimney’s connection to the roof watertight. Damage or age will affect how well flashing protects against leaks.    

Does the roof have discoloration or black streaks?

Discoloration and streaking can signal algae, moss or fungus growth on your roof. This problem occurs in areas with higher humidity and moisture, like the Portland area. Invaders feed on the shingle granules, eroding the roof more quickly. Significant discoloration may indicate roof damage and the need for replacement.

Are your energy bills rising?

If the weather hasn’t changed and your family isn’t messing with the thermostat, but you see higher heating or cooling bills, this may indicate your roof isn’t effectively insulating your home.
