Norman roofs face repeated cycles of humid summers and sudden cold fronts that spawn severe thunderstorms. These storms drive water under step flashing and rubber boots on skylights, especially on homes built in the 1970s and 1980s around Campus Corner and Hall Park. Flashing repair begins with identifying whether the leak originates at the curb, the step flashing seams, or the counter-flashing tucked behind siding. We match existing materials—galvanized steel, copper, or lead-coated copper—rather than forcing a one-size kit that fails again in the next hail event.
Older neighborhoods near the University of Oklahoma campus often have low-slope sections or complex roof-to-wall transitions where standard step flashing was never properly woven with the shingles. In these cases we remove only the damaged courses, re-lay new step flashing with the correct overlap, and seal the top edge with high-temperature butyl tape before reinstalling shingles. This approach avoids disturbing sound flashing elsewhere and keeps the repair localized so the rest of the roof can continue aging naturally.
Cleveland County building code requires flashing to extend at least 4 inches up the skylight curb and 6 inches onto the roof plane. When we encounter skylights added after original construction, the original curb flashing is frequently too short or was never counter-flashed. We extend the flashing properly and integrate new step flashing so water cannot migrate behind the skylight during the heavy rains common in spring and fall.
Technician insight
In Norman the thing that catches most people out with Skylight Flashing Repair is the way spring thunderstorms hit low-pitch roofs near Lake Thunderbird. Homeowners assume a new skylight will solve the leak when the real issue is 30-year-old step flashing that was never counter-flashed properly on the original build.
Moore Home After Repeated Spring Storms
Water stains appeared above a bedroom skylight after three consecutive thunderstorms. We found the original step flashing had corroded at the seams and the rubber boot had split. We replaced the boot, re-wove new step flashing on both sides, and added counter flashing along the curb. No further leaks occurred through the next winter.

Final Water Test
We run a controlled hose test to confirm the repair holds before leaving the site.
