Commercial Roofing Contractors in St Louis, MO

Single-ply membranes dominate new commercial construction in St. Louis. TPO (thermoplastic polyolefin) is the most popular system for new installs — white or light gray, heat-welded seams, reflective surface that reduces cooling loads, and manufacturer warranties covering 15–20 years. We work with Carlisle, Versico, and GAF TPO systems at 60-mil thickness as a standard specification for longevity.

EPDM (ethylene propylene diene monomer) — the black rubber single-ply membrane — has a longer track record than TPO and performs exceptionally in retrofit applications where the existing substrate is uneven or complex. EPDM is mechanically fastened, adhered, or ballasted depending on the building and wind zone. For high-traffic roofs, modified bitumen — a multi-ply asphalt-based system typically torch-applied or cold-process — offers superior puncture resistance and walkability.

Built-up roofing (BUR) — gravel-surfaced, multi-ply asphalt systems — is less common on new work but still the right answer for certain heavy-use or fire-rated applications. We also install reflective and silicone coatings to extend the life of existing membranes by 10–15 years when the base membrane is structurally sound.

Commercial roofing projects happen over occupied buildings. Schools are in session. Offices are open. Retail is transacting. Revolve's project management approach starts with a pre-construction meeting that maps the phasing plan, noise-sensitive hours, staging areas, daily cleanup requirements, and who to call if something unexpected comes up. We assign a single point of contact for the entire project — one person who knows the scope, the schedule, and your building.

Phasing is planned around your operations, not ours. Sections of the roof are done sequentially so the building always has a weathered-in area — no large open areas overnight. Temporary drainage and tie-offs are installed before any existing material is disturbed. At the end of each day, the site is cleaned, staging is secured, and the next day's sequence is confirmed.

Most commercial roof failures are preventable with a regular inspection and minor-repair program. The most damaging issues — blocked drains, open seams at flashing terminations, cracked sealant around pipe penetrations — are cheap to fix when caught early and expensive when found after water has migrated into the roof assembly.

Revolve offers quarterly and biannual commercial inspection programs with written reports, photo documentation, and a defined minor-repair allowance. We track the history of each roof we service, so we can tell you when the overall membrane is approaching end of life and help you budget for replacement before an emergency forces the decision.
