How to Know if You Need a New Roof
September, 2008
Clearly, a leaking roof requires repair or even replacement. But how do you identify issues before the leak starts? It’s good practice to inspect your roof regularly in the spring and the fall. Every roof will show signs of wear and tear, so how do you know what is normal and what might require major work?
- Begin by viewing the roof from a distance and look for:
- Missing shingles (or tiles for tile roofs)
- Shingle/tile lines are still straight
- Singles still have a good area of overlap
- Gutters are not sagging or loose
- Sagging in the middle or at the ridge line
Next, use a ladder to get a close-up view of the roof. Avoid walking on the roof during inspection as this can worsen any damage.
- Check flashing around vents, chimneys and valley for cracks or holes
- Check shingles/tiles for holes, excessive cracking or deterioration
- Check caulking or grout for deterioration
- Look for popped or missing nails and make sure no shingles are loose
- Look for rotting in any areas that have been exposed
- Clear off any moss or algae that might be growing in shady areas
- Look for excessive shingle granules in the gutters
- Make sure gutters and downspouts are securely attached and there is no blockage
Now, go into the attic and check the structure and underside of the roof.
- Check for puddles, excessive condensation, dark spots, streaks or any traces of water
- Look carefully for other signs of water leakage, like damaged insulation or rotted wood
- Look for any outside light showing through
- Inspect the ridge vents and soffit vents to insure that nothing is blocking the air flow
If you find signs of leaking or wear and tear, it doesn’t necessarily mean you need a new roof. If your roof is less than 15-20 years old and the damage is contained to one area a repair may be all that is required. If you have isolated damage, contact a qualified roofing specialist to inspect the roof and provide a repair estimate.
If yours is an older roof that continues to need repairs it may be worth replacing the roof. Remember, damage from recurring leaks can cost more in repair to other areas of your home. It may be more cost-effective to replace the roof to insure no further damage to the attic and/or interior ceilings or walls.
As with most things in life, prevention is the best cure. To keep your roof in top shape:
- Inspect your roof every spring and fall
- Repair or replace loose or damage shingles immediately
- Repair or replace cracked or corroded flashing
- Keep gutters clean and downspouts open
- Keep tree branches trimmed and away from the roof and clean off any leaf debris
- Keep the attic properly ventilated
- Contact a qualified roof inspector if you have any concerns
Make it a habit to inspect and maintain your roof and it will last for years.
