Roofers for small commercial buildings in Pittsburgh
Small commercial roofs are their own trade. A roof leak over a shop, an apartment or an office is a business problem as much as a building problem. We repair and replace low-slope commercial roofs and work around your tenants, customers and hours.
Priced by the building
Buildings we work on
Pittsburgh's main streets are full of older mixed-use buildings with several roofing layers, parapet walls and a shared history of patches. As roofers in Pittsburgh, PA, we work on those, as well as apartment buildings, offices, churches, schools and small industrial buildings. Our work centers on low-slope roofs, along with the sheet metal and flashing that keeps them tight.
- Storefronts and mixed-use buildings
- Churches and community buildings
- Offices and small warehouses
- Rooftop unit curbs and penetrations
Repair, restore or replace
We start with the condition of the roof and what is underneath it. If the membrane is sound, targeted repairs and a maintenance plan can buy years. If the insulation is wet or the roof is at the end of its life, we will give you a replacement price and a plan for working around your occupants. Tenant notice, crane or material access and noise windows all get agreed in advance.
Maintenance that protects the roof
Most commercial leaks start at drains, flashing and rooftop equipment, and many could be caught early. A twice-a-year inspection, once after fall leaves and once after winter, clears drains, checks seams and gives you dated photos for your records.

Common questions
What is the best flat roof system?
For most commercial buildings here, TPO or EPDM. The right one depends on the deck, insulation, rooftop equipment and how the building is used.
What is the minimum slope for a flat roof?
Pennsylvania's building code, as of 2026, calls for at least 1/4 inch per foot on new single-ply roofs such as TPO and EPDM. A replacement roof doesn't have to meet that minimum as long as it still drains.
How often should you inspect a flat roof?
Twice a year, usually spring and fall, and after any major storm.
What is the best flat roof covering?
On commercial buildings here, usually a single-ply membrane such as TPO or EPDM, chosen to suit the deck and rooftop equipment. Work can usually go on while your business stays open.
Can you repair a leaking flat roof?
Usually, yes, including roofs put on by someone else. We find the entry point first, then repair or replace that section.
