Repair or Replace? How to Tell

Signs That Usually Mean Repair

Plenty of alarming-looking roof problems are localised and ordinary:

• A single leak in one location — very often flashing, a pipe boot, or a valley rather than the field of the roof.
• A few missing shingles after a storm, with the rest of the roof sound.
• Damaged flashing at a chimney or wall.
• A cracked or perished pipe boot — extremely common here, since UV destroys the rubber.
• Isolated storm damage confined to one slope or one area.

These are the everyday content of the roof repair page, and paying to replace a whole roof over any of them alone would be a poor decision.

Signs That Usually Mean Replacement

• Widespread granule loss. Gutters full of granules and visibly bald patches mean the asphalt is exposed. That is wear, and wear cannot be patched.
• Curling or cupping across large areas. Shingle edges lifting broadly indicates the material has lost its flexibility — a Gulf Coast heat and UV signature.
• Leaks in several unrelated places. One leak is an event. Several at once is a pattern, and the pattern is the roof.
• Visible sagging. Look at the roofline against the sky. Dips or waves suggest decking or structure. Get this looked at promptly.
• Daylight through the decking, visible from the attic.
• Repeated repairs to the same roof. When you have paid for the third repair in a couple of years, the repairs have become the expensive option.

The Arithmetic

The usual rule applies: past expected service life, if a repair costs a substantial fraction of replacement, replacement generally wins. Two local factors push that threshold earlier here.

First, roofs age faster on this coast than national figures suggest, so a roof's stated age understates how much life it has used. Second, storm season is never far away, and a marginal roof going into it is a gamble on your own house.

What you should expect from anyone assessing it: the repair cost, the replacement cost, a clear statement of what is likely to fail next, and whether the proposed repair is a genuine fix or a stopgap. A roof inspection should produce all four. If the damage is storm-related, the insurance claim guide covers how that changes the picture.
