Commercial TPO roofing in Miami.

TPO, short for thermoplastic polyolefin, is a single-ply membrane used on flat and low-slope commercial roofs. Caston Roofing installs, repairs and maintains TPO roofs for Miami-Dade businesses, and a free roof inspection tells you whether yours needs a repair or a replacement.

What a TPO roof is

TPO sits alongside EPDM and PVC among the single-ply membranes used on flat roofs (Wikipedia, Flat roof). White TPO reflects sunlight, which is why it is counted as a cool roof material (Wikipedia, Cool roof).

Where TPO fits

TPO is a flat-roof and low-slope system. In Miami-Dade that means shops, light industrial buildings and multi-unit buildings, where the roof is a large open surface and the seams, drains and edge details decide how long it lasts. Standing water contributes to premature deterioration of most roofing materials (Wikipedia, Roof), so drainage gets as much attention as the membrane.

• Open or lifting seams
• Punctures and worn edge details
• Ponding and slow drains
• Failed flashing at curbs, vents and walls

We see the same problems on commercial roofs in Doral and Hialeah. If water is already coming in, start with roof leak repair.

Hurricane zone rules and product approval

Miami-Dade and Broward are Florida's High-Velocity Hurricane Zone, which carries more stringent requirements than the rest of the state (Wikipedia, Florida Building Code). In Miami-Dade, roofing products are reviewed by the county's Product Control Section, which keeps a searchable product approval database. Permit checklists can ask for a Notice of Acceptance or product approval for each roof component; Coral Gables' re-roof requirements are one example, and the county explains how to apply for a permit. Before work starts we tell you what permits and approvals your building needs.

How a TPO job runs

• Free roof inspection: seams, flashing, drains, edges and the condition of what is on the roof now.
• A clear written estimate in plain language before any work begins.
• Permits and product approvals confirmed before work starts.
• Repair or replacement. Limited damage is usually a repair; a roof at the end of its life is a replacement.
• Follow-up roof inspections so seam and drainage problems are caught early.
