The short answer

A roof leak in Carbondale almost never starts where the stain appears. Water enters at a flashing, boot, valley or fastener, travels along the deck and rafters, and shows up feet away. Leak repair means finding the entry point, photographing it, and fixing the cause.

The stain on a ceiling is where the water finally gave up, not where it got in. Chasing the stain is why some leaks get sealed three times and keep coming back every heavy rain.

In this housing stock the usual suspects are consistent: dried and split plumbing vent boots, step flashing at a sidewall or dormer that was caulked instead of woven in, chimney counterflashing that was never cut into the mortar, valleys with debris packed in from Carbondale's heavy tree cover, and nail pops from thermal cycling that lift a shingle just enough.

We work the roof and the attic together. From inside you can read the path of the water on the sheathing and rafters, which usually points straight at the entry point above.

When to call us

  • A ceiling or wall stain, especially one that grows after rain
  • Drips during heavy or wind-driven rain but not light rain
  • Musty smell or damp insulation in the attic
  • Staining or rust streaks on attic sheathing, rafters or nails
  • Bubbling paint or sagging drywall near an exterior wall
  • Water around a chimney, skylight, or bathroom vent

Roof Leak Repair questions

Why does my roof only leak in certain storms?
Wind-driven rain gets under and sideways into places straight rain never reaches. A leak that only shows in a south wind is telling you where to look.
Can a roof leak without any missing shingles?
Constantly. Most leaks we repair are flashing and penetration failures on roofs that look fine from the street.
Will one leak mean I need a whole roof?
Not usually. One failed boot on a sound roof is a repair. Multiple leaks in different areas on an aging roof is a different conversation, and we will be straight with you about which you have.
