Quick answer: John Beal Roofing installs, repairs and replaces TPO commercial roofing in the City of St. Louis and St. Louis County. TPO is a white, reflective single-ply membrane with heat-welded seams, typically 45, 60 or 80 mil, and it is the most common choice for flat and low-slope commercial roofs here.

TPO roofing for St. Louis buildings
St. Louis puts a flat roof through a lot: humid 95-degree summers, freeze-thaw winters and spring hail. TPO handles that well when it is installed right. The seams are hot-air welded rather than glued, so a properly welded seam is stronger than the sheet itself, and the white surface reflects much of the summer sun instead of baking the floor below.
We install TPO on warehouses and distribution buildings, strip centers and retail, offices, churches, schools, apartment and condo buildings, and flat sections of homes — from the riverfront to St. Louis County.
TPO installation methods
- Mechanically attached — fastened through the insulation into the deck; efficient on large, open roofs.
- Fully adhered — bonded to the substrate; smooth, quiet and strong against wind uplift.
- Induction welded — plates under the membrane are welded to it, with no holes through the sheet.
Thickness, insulation, edge metal and drainage are chosen for your building. We also install EPDM, modified bitumen and roof coatings, and we will tell you which system fits and why.
TPO roof repair in St. Louis
Most TPO leaks start at the same places: open or poorly welded seams, punctures from foot traffic or dropped tools, flashing at curbs, walls and drains, and ponding water where the roof does not drain. We find the source, heat-weld repairs, and photograph the work so you have a record. Recent examples include a TPO repair on Buckland Hall Road in St. Louis and a dead-valley TPO repair in Pacific.
Repair, restore or replace?
If the membrane is sound, repair or a restoration coating can add years. If the insulation is wet or the sheet is failing across the roof, replacement is the better spend. We show you core samples, photos and moisture findings so the decision is based on evidence.

Frequently asked questions
- Do you install TPO roofing in St. Louis?
- Yes. John Beal Roofing installs, repairs and replaces TPO roofs on commercial and multi-family buildings across the City of St. Louis and St. Louis County. Call 314-429-6000, answered 24/7.
- How long does a TPO roof last in St. Louis?
- A correctly installed TPO roof commonly lasts 20 years or more. Thickness, seam quality, drainage and maintenance matter more than anything else. St. Louis heat, freeze-thaw cycles and hail are why seams and flashings should be inspected regularly.
- What thickness of TPO should I use?
- TPO is typically installed in 45, 60 or 80 mil. Thicker membranes hold up better to foot traffic, hail and age. We recommend a thickness based on the building, its use and how long you plan to own it.
- Can a leaking TPO roof be repaired instead of replaced?
- Often, yes. Open seams, punctures and failed flashings can be heat-welded and patched. If the membrane is saturated or failing across the roof, we will show you the evidence and price replacement.
- Is a white TPO roof worth it in St. Louis summers?
- A white, reflective TPO surface reflects much of the sun's heat, which can reduce the cooling load on the floor below during St. Louis summers. Gray and tan are available when appearance matters.
