Clarksville's housing stock ranges from 1920s bungalows in Downtown and New Providence to 1970s ranchers in Hilldale and St. Bethlehem. Many of these roofs still carry original curb-mounted skylights whose seals have dried out after decades of humid subtropical summers and occasional winter freezes. When replacing, we remove the old unit entirely rather than layering new flashing over failed material, which prevents water from migrating under the shingles during the heavy spring rains that hit Montgomery County.
Hot summers here expand and contract metal frames faster than in drier regions, so we use thermally broken aluminum or fiberglass frames with butyl tape and step flashing that ties into the existing shingle courses. Homes near Fort Campbell or along the Cumberland River often sit on slightly sloped lots where runoff concentrates at the skylight curb; we add cricket flashing behind the unit to divert water. This detail is especially important on the steeper pitches common in Sango and near Roxy Regional Theatre neighborhoods.
Building codes in Montgomery County now require tempered glass or laminated options on skylights above living spaces. We match the existing rough opening when possible to avoid reframing, but on 1950s homes the openings are frequently out of square, so we scribe new curbs on site. Proper ventilation during install keeps condensation from forming on the new glass during the muggy months between May and September.
Technician insight
In Clarksville the thing that catches most people out with Skylight Replacement is the way our humid summers and occasional hard freezes make old butyl seals brittle on the north-facing slopes common in Hilldale and New Providence. Homeowners often think a new pane will solve it, but without pulling the curb and redoing the step flashing the leak just moves six inches down the roof.
Hilldale Ranch Leak
A 1972 ranch in Hilldale had water staining around a 4x4 skylight after heavy spring rains. We found the original curb flashing had pulled away where the roof met the slight slope toward the Cumberland. Removed the old unit, rebuilt the curb square, installed a new fiberglass frame with cricket, and tied everything into the existing shingles. No more moisture showed up in the attic after the next rain.
