Roofer in Claymont, DE

Older Claymont roofs often have aging flashing and multiple shingle layers, and the flashing where the chimney meets the roof is the single most common leak point. Over the decades the original step and counter-flashing corrodes and the mortar joint opens up, and exposure to river winds and Atlantic nor’easters drives water into those gaps. Because the water then runs along the decking, the leak usually shows up as a ceiling stain some distance from the chimney and gets blamed on the shingles. We trace it to the actual source and reseal or replace the flashing there, so it stops instead of returning with the next storm. Call (302) 618-1471.

We can — ice dams are a recurring winter problem on Claymont’s older, river-exposed homes. They form when heat escaping through an under-ventilated attic melts roof snow, which refreezes at the cold eaves and backs meltwater up under the shingles until it finds a gap. The lasting fix addresses the causes — attic ventilation and insulation, plus proper flashing and ice-and-water shield at the eaves — not just the interior stain. We diagnose why the dams are forming on your roof and correct it, so you’re not chasing the same leak every thaw. Call (302) 618-1471 if you’re seeing winter ceiling stains.
