Pueblo's semi-arid climate brings intense summer UV and occasional heavy spring rains that quickly degrade commercial skylight seals and flashings on flat-roof buildings in Downtown Pueblo and Belmont. Older commercial stock from the mid-20th century often uses acrylic or polycarbonate domes set in aluminum curbs that expand and contract with daily temperature swings, leading to cracked gaskets and water intrusion at the curb-to-roof transition. We focus on matching existing curb heights and slope to maintain code-compliant drainage without raising the roof edge.
Access on single-story retail and light-industrial buildings near the Pueblo Riverwalk or Lake Minnequa usually requires boom lifts rather than scaffolding, and we coordinate with property managers to minimize disruption during business hours. Edge cases include skylights mounted over suspended ceilings where moisture has already stained tiles, requiring us to trace the leak path through insulation before any surface repair. We always check for prior patch attempts that trap water and accelerate rust on metal curbs common in Highland Park commercial properties.
When replacing glazing we use UV-stabilized polycarbonate or laminated glass rated for Pueblo's hail exposure and wind loads, securing new units with butyl tape and termination bars rather than relying solely on caulk. This approach holds up better against the mild winter freeze-thaw cycles that can separate poorly adhered sealants within two seasons.
Technician insight
In Pueblo the thing that catches most people out with commercial skylight repair is how quickly UV and 100-degree summer days turn butyl tape brittle on buildings in Downtown Pueblo and Belmont, so a leak that looks like a simple seal job often reveals rotted curb wood once we open it up.
Retail building near Pueblo Union Depot
Water stains appeared on ceiling tiles above the sales floor after spring rains. We found the original acrylic dome had crazed and the curb flashing had pulled away at one corner. We replaced the dome with hail-rated polycarbonate, rebuilt the flashing with new termination bar, and tested the repair during the next rain event. No further leaks occurred.

How it works
- 1
Site Inspection
We examine every commercial skylight on the roof, checking seals, curbs, and surrounding membrane condition while noting access limitations.
- 2
Leak Source Confirmation
Targeted testing isolates whether water enters at the glazing, curb, or roof transition before any repair begins.
- 3
Material Matching And Repair
We select compatible glazing and flashing materials sized for the existing curb and install them to maintain roof slope and drainage.
- 4
Final Water Test And Cleanup
After completion we retest the repaired skylights and remove all debris so the building can reopen without roof-related issues.
