Roof Repair or Full Replacement? How to Decide (The Woodlands, Cypress & Spring)

The question behind the question

When a homeowner in The Woodlands calls and asks "do I need a whole new roof or can you just fix it," what they usually mean is: is someone about to talk me into the expensive option? Fair concern. So here is the framework we use, written down, so you can apply it before anyone gets on your roof.

Repair is the right call when all of these are true

• The damage has a boundary. One leak, one valley, one slope that took wind. You can point at it.
• The roof is under roughly 15 years old and the rest of the field still has its granules.
• The decking is solid. No sponginess, no sag, no daylight in the attic outside the damaged area.
• The cause was an event, not age. A branch came down, a boot cracked, wind lifted a course.

In that situation a targeted repair is not a stopgap. It is the correct repair, and replacing the whole roof would be spending twenty thousand dollars to solve a four hundred dollar problem.

Replacement is the right call when any of these are true

• The roof is past 20 years. Asphalt shingle in Gulf heat and UV does not make it far beyond that, whatever the wrapper said.
• Roughly 30 percent or more of the surface is compromised. At that point you are patching a roof that is failing everywhere at once.
• Granule loss is systemic. Not a cupful after a storm — piles in the gutters every time it rains, and bald shiny patches visible from the ground.
• The decking is soft. If the deck has taken water, shingles on top of it will not stay put.
• You are filing a storm claim that the carrier has approved for replacement. Take the replacement.
• You are seeing leaks in more than one place. Multiple leak points on an older roof is a system telling you it is done.

The 30 percent rule

Here is the arithmetic we give homeowners. Get a real repair number and a real replacement number. If the repair is more than about 30 percent of the replacement, and the roof is past the halfway point of its life, replace it. Below that threshold and with life left, repair it.

It is a rule of thumb rather than a law, but it stops the two expensive mistakes: replacing a roof that had eight good years left, and pouring three thousand dollars of repairs into a roof that fails completely eighteen months later.

The third option: your attic is why the roof is dying early

This is the one that gets skipped, and in this climate it matters enormously. If a roof is failing noticeably before 20 years, the reason is often not the shingle — it is that the attic underneath it cannot breathe.

An under-ventilated attic in a Houston-area summer runs punishing temperatures. That heat cooks the asphalt from the back side, dries out the binder, and ages the roof from underneath where nobody is looking. Add Gulf humidity with nowhere to go and you get moisture sitting against the decking year-round.

If your roof is 12 years old and already looks 20, before you spend on replacement, get the ventilation assessed. Correcting intake and exhaust is a four-figure job, not a five-figure one, and on the right house it adds years to the roof you already own — while dropping the upstairs cooling load at the same time. We would rather sell you vents that work than a replacement roof that fails early for the same reason the last one did.

Five questions to ask whoever inspects your roof

1. Show me the photos. Not a description — the actual images of the actual damage. We leave you the photo report either way.
2. What is the decking condition? If they cannot speak to it, they did not really look.
3. What happens if I repair and it fails anyway? A real contractor will tell you what the repair does and does not cover.
4. How is my attic ventilated, and is it adequate? The answer tells you instantly how thorough the inspection was.
5. What is the workmanship warranty on this specific work, in writing?

Why we will talk you out of work

Martha Cano owns Tex-Mex Roofing, has been in roofing for over 20 years, and is on the roof herself. When the person who writes the estimate is also the person who has to stand behind the installation, there is no incentive to sell a replacement to a roof that needed a repair — the callback lands on her either way.

So we will tell you when a repair is enough. We will tell you when ventilation is the actual problem. And we will tell you plainly when a roof is finished, because letting a failing roof run another season costs more in decking, insulation and drywall than it saves.
