Lehi's semi-arid climate creates repeated expansion and contraction cycles that degrade skylight seals faster than in milder regions. Homes built in the 2000s around Thanksgiving Point and The Preserve often use acrylic or polycarbonate domes whose gaskets fail after 12–15 years when winter lows drop below freezing. Older stock near Lehi Main Street District may have original aluminum-framed units with corroded flashing that channels meltwater under the roof deck during spring thaws.
Proper repair starts with tracing the actual leak path rather than assuming the skylight itself is the sole culprit. In Jordan Willows and South Lehi, steep roof pitches combined with wind-driven rain from the west can force water past step flashing that was never properly integrated with the skylight curb. Technicians must lift adjacent shingles, inspect the cricket, and verify that the new butyl tape or membrane ties into the existing underlayment without creating a new dam point.
Edge cases appear regularly near the Utah State Developmental Center where irrigation overspray keeps roof planes damp longer, accelerating sealant breakdown. Replacement glass must match the original thermal rating to avoid condensation issues inside the home during cold snaps. All work follows current IRC requirements for curb height and cricket sizing when the skylight is removed for access.
Technician insight
In Lehi, the thing that catches most people out with Skylight Leak Repair is assuming the dome itself is leaking when the real problem is the step flashing that was never properly woven into the underlayment on homes built along Dry Creek. Those 2000s builds around Thanksgiving Point see the worst damage after a hard freeze because the butyl tape loses elasticity and water finds the nail holes.
Dry Creek Skylight Leak After Winter Freeze
Water stains appeared on a ceiling in a 2008 home in Dry Creek following January lows. Inspection showed the skylight curb flashing had pulled away where it met the valley. We lifted shingles, replaced the step flashing with new copper, re-taped the curb, and restored the shingles. The homeowner reported no further staining after the next snow melt.
