When to Repair Your Roof vs. When to Replace It

Every roofing salesperson in North Texas wants to sell you a full reroof. We get it — the margin is bigger and the job is more predictable. But about half the roofs we are called to look at do not need replacing. They need a single repair, sometimes two, and a homeowner who knows the difference saves a lot of money.

Signs you need a repair (not a replacement)

If the rest of the roof is in solid shape and the leak is localized, you are almost always looking at a repair. The usual suspects:

• A single torn or missing shingle in one spot
• A cracked or split pipe boot at a plumbing vent
• Loose step flashing where the roof meets a wall or chimney
• A popped nail head poking through a shingle
• A wind-blown ridge cap that lifted in a storm

These are all sub-$800 fixes. None of them justify replacing 28 squares of perfectly good roof.

Signs you actually need a replacement

These are systemic issues — meaning the roof as a whole is failing, not just one component:

• Granules filling your gutters and downspouts (the shingles have lost their UV shield)
• Curling or cupping shingles across multiple slopes
• Bald spots where the asphalt mat is visible through the granules
• Active leaks in three or more separate areas
• A decking dip you can see from the street (soft spots beneath the shingles)
• The roof is more than 22 years old and storms keep finding new weak spots

The 25-percent rule

Old industry rule of thumb: if more than 25 percent of the roof needs work, replace it. Anything under that line, repair what is failing and leave the rest. We modify this slightly for Texas homes — insurance carriers will only pay for partial repairs once or twice before they push you toward a full replacement on the next claim. If you are already on your second repair claim in five years, the next storm is going to force the issue anyway.

Get a second opinion before you sign anything

If a contractor walks your roof and immediately quotes a $15,000 replacement, ask for the specific evidence. Photos of the damage. Square-foot count of affected area. A second look at the underlayment, not just the shingles. A second opinion takes 30 minutes and can save you five figures.
