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. Shaw Island Roofing & Maintenance installs and repairs all of them across Shaw Island.
Our Commercial Roofing Process
Free Assessment
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.
Scope & Estimate
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
Installation phased to minimize disruption to your tenants and business operations. Debris containment, noise management, and clean work areas maintained throughout the project. Project manager on-site for every commercial installation.
Final Inspection
Your commercial roof gets a detailed completion package: as-built documentation, warranty certificates, maintenance recommendations, and emergency contact information for Shaw Island Roofing & Maintenance.

About Our Shaw Island Commercial Roofing Services
TPO is our most-installed commercial membrane in Shaw Island. White reflective surface for energy efficiency, hot-air welded seams that are stronger than the membrane itself, and 15-20 year manufacturer warranties. We install 60-mil and 80-mil systems, fully adhered or mechanically attached, over polyiso insulation.
Multi-family properties need roofing contractors who understand occupied buildings. Leak repairs are emergencies when water is in someone's apartment. Shaw Island Roofing & Maintenance prioritizes multi-family emergency calls and schedules planned work during reasonable hours.
