A leak or a few missing shingles doesn’t always mean you need a new roof. But when repairs keep coming back, replacing the roof can cost less over time. Here’s how to weigh up the two.
Start with the age of the roof
Most asphalt shingle roofs last 20 to 30 years, depending on the shingles, the ventilation underneath and how many freeze–thaw winters they’ve been through. If your roof is under 15 years old and the damage is limited to one area, a repair usually makes sense. Past 20 years, curling or cracked shingles, bare patches where the granules have washed off and leaks that keep returning are signs the whole roof is wearing out.
Look at how widespread the problem is
Look at the roof from the ground, then check the attic on a sunny day. A single ceiling stain, or a few shingles lifted after a storm, points to a local problem. Stains in several rooms, daylight through the roof boards or damp insulation suggest the roof covering, or the deck beneath it, is failing more widely.
- Isolated damage in one area often suits a repair
- Leaks in several places point to wider wear
- Sagging or soft decking needs a closer look
Not sure which applies to you?
An inspection lets you compare repair and replacement side by side, with a written estimate for each.
Compare the long-term cost
A repair costs less today, but each one adds to the total. If you expect to repair the same roof again within a few years, add those costs together and compare them with a replacement estimate. Ask for both options in writing, including the condition of the decking, ventilation and flashing, so you can compare like for like. Not sure where you stand? Call ADZ Roofing on (201) 565-6664.
