Commercial roofing is a different discipline from residential. Flat and low-slope systems (TPO, EPDM, PVC, modified bitumen, and built-up roofing) each have specific installation requirements and performance characteristics. Trenary Roofing & Maintenance installs and repairs all of them across Trenary.
Commercial roof coatings can extend the life of an existing roof by 10-15 years for a fraction of replacement cost. Silicone and acrylic coatings over existing TPO, EPDM, or metal substrates. Not every roof qualifies. We core sample and moisture scan before recommending a coating.
Our Commercial Roofing Process
Building Inspection
Before we recommend anything, we inspect everything. Membrane, seams, flashings, drains, penetrations, parapet walls, and rooftop equipment curbs. Core samples test for trapped moisture in the insulation. Honest assessment. No scare tactics.
Detailed Proposal
Your proposal includes material specifications, installation method, warranty terms, project timeline, and total cost. We itemize everything and explain why we're recommending the specific system for your building.
Professional Installation
Factory-trained crews using proper equipment, hot-air welders for TPO/PVC, torch equipment for modified bitumen, and adhesive systems for EPDM. Every seam, flashing, and penetration detail inspected before we leave.
Final Inspection
Your commercial roof gets a detailed completion package: as-built documentation, warranty certificates, maintenance recommendations, and emergency contact information for Trenary Roofing & Maintenance.
