Clarksville's humid subtropical summers drive rapid expansion and contraction around skylight curbs, especially on roofs facing the Cumberland River where morning fog adds extra moisture. In older housing stock found in Downtown Clarksville and New Providence, original step flashing often sits under multiple layers of shingles that have already been patched after past storms rolling in from Nashville. Proper repair requires lifting the surrounding shingles without disturbing the decking, then installing new counter-flashing that ties into the existing step flashing rather than relying on caulk alone.
Homes in Hilldale and Sango built in the 1980s and 1990s frequently used curb-mounted skylights with thin aluminum flashing that corrodes at the corners once the original sealant fails. We remove the skylight, inspect the curb for rot, and install new 16-ounce copper or lead-coated copper flashing that extends at least six inches up the curb and four inches onto the roof deck. This approach handles the mild winter freeze-thaw cycles without cracking the way cheaper butyl tape repairs do after two seasons.
Access matters on the steeper roofs common near Fort Campbell and along the river bluffs. We stage ladders from the street side in tight lots and use roof jacks to avoid crushing shingles that have already softened in the summer heat. Every repair includes a water test from the roof the same day so homeowners know the flashing is seated before we leave the job.
Technician insight
In Clarksville the thing that catches most people out with Skylight Flashing Repair is how the humid summers plus river fog rot the curb wood itself on 1980s homes in Sango and New Providence before the leak even shows up inside.
Hilldale Roof Leak After Summer Storms
Homeowner noticed water stains on a bedroom ceiling after heavy rain. We found corroded aluminum flashing at the skylight curb on a south-facing slope. Removed the skylight, replaced the step and counter flashing with copper, sealed the curb, and reinstalled. No further leaks after the next rain event.
