Reading's housing stock from the early 1900s through the 1950s often features original curb-mounted skylights set into slate or asphalt roofs. These units expand and contract sharply during Berks County's humid continental summers and repeated freeze-thaw winters, breaking the original sealants at the curb-to-roof transition. Technicians routinely find that the lead step flashing has pulled away or that the skylight's own aluminum frame has corroded at the corners where condensation pools.
When leaks appear near the Reading Public Museum neighborhood or along the slopes facing the Pagoda, the first step is always to differentiate between skylight failure and adjacent roof-plane issues. Many calls originate after heavy summer storms when water tracks under the skylight flashing and follows rafters into second-floor ceilings. Proper diagnosis requires lifting the surrounding shingles rather than relying on interior water stains alone.
Repairs focus on restoring the original curb height and integrating new self-adhered membrane with the existing flashing rather than overlaying new material that can trap moisture. In West Reading and Hyde Park homes, crews also check for missing cricket flashing behind larger skylights, a detail frequently omitted on additions built before current Berks County permitting standards tightened.
Technician insight
In Reading, the thing that catches most people out with Skylight Leak Repair is assuming the leak is only at the glass when the real failure is the original curb flashing pulling away on 80-year-old homes after repeated summer expansion and winter contraction cycles common between Downtown Reading and Mount Penn.
West Reading Addition Skylight
Homeowner noticed ceiling stains after a July storm. Inspection showed the skylight curb on the 1960s addition had lost its sealant and the step flashing had lifted. Crew reset the flashing, installed new curb tape, and added a small cricket. No further leaks appeared after the next heavy rain.

How it works
- 1
On-Site Leak Tracing
Technician climbs the roof from the street side in neighborhoods like Hyde Park, uses a moisture meter on interior ceilings, then traces water paths back to the skylight curb.
- 2
Flashing and Seal Assessment
Removes adjacent shingles to inspect step flashing and curb sealant condition, noting any corrosion or thermal gaps typical after decades on Berks County roofs.
- 3
Targeted Repair Execution
Replaces or resets only the failed components, integrates new membrane, and restores shingles so the repair blends with the existing roof plane.
- 4
Final Water Test
Runs a controlled hose test from the ridge line to confirm no water enters the skylight or surrounding roof before leaving the property.
Pricing
Most skylight leak repairs in Reading fall between a targeted curb seal and a full flashing rebuild; exact scope is confirmed after the roof inspection.
