Chimney Flashing Repair in Denton, TX
Where a roof meets brick is where most roofs eventually leak. Done correctly by a careful local roofer, that seam is a two-part metal system, not a bead of caulk with good intentions.
Flashing is the metal that seals every place a roof cannot simply shingle over: chimneys, walls, valleys, and skylights. When it is right, nobody thinks about it for twenty years.
The shallow groove cut into a mortar joint that counter flashing locks into. Setting metal into the masonry, instead of gluing it onto the surface, is what lets a chimney seam survive freeze-thaw cycles and wind. If a flashing quote never mentions cutting or grinding, the metal is probably just getting caulked on.
A chimney gets a two-part system. Step flashing weaves under the shingles course by course along the sides, and counter flashing sets into a groove cut in the mortar and folds down over the steps, so water sheds metal-over-metal the whole way down. The common shortcut around older Denton masonry is smearing sealant over tired flashing and calling it repaired, which holds through a season or two of freeze-thaw and then leaks in the same place, plus interest.
Wind gives flashing its own trouble in this county. Gusts on the record here have crossed 90 mph, and repeated storms work counter flashing out of shallow mortar joints and lift step flashing where nails backed out. The fix that lasts is mechanical: the roofer rebuilds the flashing system piece by piece, re-cutting the reglet where the mortar joint has failed, rather than gluing the old metal back down. The same standard applies at sidewalls, dormers, and the valleys that carry the most water on the roof.
If a ceiling stain sits near the fireplace, flashing is the first suspect, but not the only one; cracked chimney crowns and brick that drinks rain produce look-alike leaks. The visit starts as detective work, photographs what is actually failing, and prices only what needs doing. A chimney rebuild you did not need is not on the menu.
