Indianapolis averages 25 freeze-thaw cycles each winter, where daytime temperatures climb above freezing and nighttime temperatures drop below 32 degrees. This constant expansion and contraction movement stresses every component of your skylight installation. Water from melting snow seeps into tiny gaps around the flashing, then freezes at night and expands. This ice formation pries the flashing away from the roof deck, creating channels for water entry. Skylights installed without proper curb height sit too low on the roof plane, letting snow accumulate against the glass. When that snow melts, the water has nowhere to drain and pools against the skylight frame until it finds a path into your attic.
Marion County building inspectors know which skylight contractors follow code and which take shortcuts. They check curb height, flashing integration with shingles, and whether ice and water shield extends far enough beyond the skylight opening. Indianapolis requires permits for skylight installations because improperly installed roof penetrations are the leading cause of residential water damage claims in Central Indiana. Elite Roofing Indianapolis has worked with every inspector in the Marion County permitting office. Our installations pass inspection on the first visit because we know exactly what the code requires and we build to those standards every time.
