Commercial roofing
Commercial roofing
Commercial roofing covers the flat and low-slope roofs on offices, retail, churches, warehouses and apartments: finding and repairing leaks, replacing membranes such as TPO or modified bitumen, and restoring sound roofs with coatings. Drainage and flashings are where most commercial roofs fail.
- Typical time
- Repairs in a day or two; replacements scheduled in phases over days to weeks.
- Repair or replace
- Repair or coat sound roofs; replace when insulation is wet or the membrane fails broadly.
Low-slope roofs don't shed water the way shingles do. Clogged drains and scuppers leave ponding water that finds every seam, and Gulf Coast downpours can drop inches of rain in an hour. Parapet walls, rooftop units and penetrations for industrial equipment all need flashing that holds up to wind.
Commercial work is planned around the building: phasing so tenants stay open, keeping the building dry during tear-off, and documenting the roof's condition for owners, managers and insurers.

Commercial Roofing: common questions
Should I recoat or replace my flat roof?
A coating can extend a roof that's structurally sound with dry insulation. If moisture surveys find widespread wet insulation or the membrane is failing everywhere, replacement is the better investment.
How long does a TPO roof last?
A well-installed TPO roof typically lasts about 20 years or more, depending on thickness, installation quality and maintenance. Heat and ponding water shorten its life.
