Commercial roof alterations & retrofits
Commercial roofs evolve. New equipment, new tenants, new codes, we adapt your roof to all of it, cutting in cleanly, flashing it right, and submitting the work so your existing manufacturer warranty stays 100% active.
Code upgrades and warranty preservation
Insulation & drainage
Energy code
Whenever a roof is opened, code requires updated R-values. We add thick polyisocyanurate layers and design custom tapered "cricket" systems that direct water straight to drains, eliminating standing water.
Coverage preserved
Warranty
Cutting blindly into a roof can void your warranty. We verify the provider first, use exact manufacturer-certified details and materials, and submit for re-inspection so coverage stays 100% active.
One roof coordinator
Coordination
We manage timelines with third-party HVAC techs, electricians and GCs, once equipment is set or a pipe is run, our crew is right behind them to dry it in and seal it before the weather shifts.
Two structural openings, zero downtime, warranty intact
BeforeAfterA tenant needed major internal exhaust-hood upgrades, cutting two 4×4-foot openings through a structurally sound EPDM deck. We built and welded heavy steel support curbs, reinforced the surrounding framing and flashed the new penetrations seamlessly.
