Commercial flat roofs face a different set of problems than residential, ponding water, membrane seams, and rooftop equipment penetrations all need to be handled correctly to avoid leaks. Primmer Roofing installs and repairs TPO membrane systems, and offers silicone coating as a lower-cost way to extend an existing flat roof’s life without a full replacement.
Whether you need a full TPO install on a new build, a membrane repair, or a coating to buy another decade out of a roof that’s still structurally sound, we’ll give you a straight recommendation, not just the most expensive option.
The layer nobody talks about
TPO does not hide underlayment under a shingle
On a low-slope roof the membrane is the waterproofing. What sits under TPO is cover board and insulation, not felt. Same idea, different stack.
The membrane is the roof
Heat-welded TPO is the water barrier. There is no decorative wear layer covering a secret sheet the way tile and shingle do.
Cover board and insulation
Those layers protect the deck, take rooftop traffic, and give the weld a solid base. Cheap board under a good membrane is still a weak roof.
Details still decide it
Drains, curbs, and wall flashings fail first. The stack under the field only matters if those transitions are welded and terminated right.

Why Tampa Bay businesses run TPO
Handles ponding water
Low-slope roofs collect water. Heat-welded TPO seams are built for that, including around HVAC curbs.
Cooler commercial decks
White TPO reflects sun, which cuts rooftop heat and takes pressure off units sitting on the membrane.
Cleaner commercial look
One welded field instead of a patchwork of coatings, with details that inspectors and insurance adjusters understand.
Residential flats too
Porches, additions, and modern low-slope homes get the same welded system we put on storefronts.
Warranties
What is actually covered
Polyglass system coverage
Primmer is Polyglass certified. TPO warranties follow the system we install, typically 15–20 years when the assembly is registered.
Coverage on the spec
Membrane thickness, insulation, and flashing details change the warranty. We write that into the proposal before tear-off.
Primmer workmanship
Welds, drains, and rooftop equipment flashings are covered by our tradesman warranty on the finished system.
Manufacturer warranties have terms, exclusions, and registration rules. We review the exact coverage with you before materials are ordered.

Common Questions
COMMERCIAL ROOFING FAQ
What’s the difference between TPO replacement and silicone coating for a commercial roof?
TPO replacement is a full new membrane system, best when the existing roof is failing structurally. Silicone coating is applied over a sound existing roof to extend its life at a fraction of the cost, see the Silicone Roof Coating page for details.
Do you handle commercial roofing on top of residential work?
Yes, Primmer Roofing services both residential and commercial properties across Hillsborough and Pinellas County.
