Flashing fails fast around Conroe chimneys because the metal gets hot in summer then cools quick at night. That movement cracks the sealant on galvanized step flashing. We pull the old stuff, check the underlayment for rot, and install new copper step flashing with 4 inch overlaps. Homeowners in April Sound and Grand Central Park see this every few years on 15-year-old roofs.
Valley flashing leaks show up after heavy spring rains in Montgomery County. Cheap crews often nail through the metal instead of using clips, which lets water sneak under the shingles. We use 16 oz copper or painted aluminum valley metal and run it full length without seams where possible. That keeps the water moving straight to the gutters even when the humidity stays high for weeks.
Downtown Conroe homes with low-slope porch roofs get flashing rot at the wall line. Mild winters keep the wood damp longer so the metal corrodes from the back side. We cut out the bad section, slip new lead flashing behind the siding, and tie it into the existing roof membrane. Permits are required if we open more than 100 square feet, so we pull those before we start.
