JC General Contractors San Antonio roofing Call (210) 468-8279

A roof repair is the right answer when the damage is contained and the rest of the roof still has service life in it. The work is finding what actually caused the leak, fixing that, and confirming the surrounding area is sound.

Where water actually gets in

The most common assumption about a roof leak is that there is a hole directly above the stain. Occasionally that is true. More often water enters somewhere else, travels along the underside of the decking or down a rafter, and drops through at the first place gravity allows.

That is why chasing the stain rarely works, and why a repair that only addresses the visible symptom tends to come back. The places we look first:

  • Flashing. Metal at the junctions: roof to wall, around the chimney, in the valleys. Flashing is where two things meet, and things that meet are where water gets through.
  • Pipe boots. The rubber collars around plumbing vents. They harden, split, and pull away with age and sun exposure.
  • Valleys. Where two roof planes meet, all the water from both planes is concentrated into one channel.
  • Fasteners. Nails backing out, or nails driven wrong the first time.
  • Wind damage. Shingles lifted or removed, exposing the underlayment or the deck.

What a repair involves

  • We find the entry point and the cause, not just the exit point.
  • We check the decking around it. If water has been getting in for a while, the wood may need to come out.
  • We fix the cause and make the area weathertight.
  • We tell you what we found, including anything we saw that is not urgent yet.

That last one matters. If we are on your roof and see something that is going to be a problem in a couple of years, you should hear about it now, while it is information rather than an emergency.

When repair is not the answer

We would rather tell you a roof can be repaired. Sometimes it cannot, and saying otherwise would be taking your money for a result that will not hold. Repair stops being sensible when:

  • The damage is not in one area. It is on every slope, and fixing one spot leaves the others.
  • The decking is soft across a broad area rather than in one patch.
  • The covering has reached the end of its service life, so a repair is holding together material that is failing anyway.
  • The roof has been repaired repeatedly in the same area and it keeps coming back.

If that is where your roof is, the honest conversation is about replacement. We will explain what we found and why, and you are free to get another opinion on it.

If you are weighing the two, we wrote a longer walk-through: Roof repair or replacement.

After a storm

Storm damage is a repair question with extra steps: documentation, timing, and knowing who to be careful of. That is covered on the storm damage roofing page.
