COMMERCIAL GRADE LOW SLOPE ROOFING
EPDM rubber roofing is the most trusted system for low-slope and flat commercial roofs. With decades of proven performance in every climate, EPDM delivers reliable waterproofing, UV resistance, and long-term durability for commercial buildings across Southern New Hampshire.
WHY BUSINESSES CHOOSE COMPASS EXTERIORS
On-the-Roof Inspections
Every commercial project starts with a thorough on-the-roof inspection, documented with photos and narrated video. We provide clear, detailed reports that building owners and property managers can use for budgeting and decision-making.
System Expertise
We install EPDM membranes in 60-mil thicknesses for maximum durability and performance. Our team understands the nuances of commercial flat roof systems, including proper adhesion methods, seam welding, and detailing around commercial penetrations like HVAC units, conduits, and drains.
Drainage & Insulation Solutions
Ponding water is the enemy of flat roofs. We engineer tapered insulation systems that create proper drainage slopes, directing water to drains and scuppers. This not only prevents ponding but also improves energy efficiency with added R-value.
Property & Tenant Protection
We understand that commercial roofing work must minimize disruption to your business operations. Our crews are trained to work efficiently, maintain clean job sites, and coordinate with building management to protect tenants and operations.
Warranties
Our commercial EPDM installations come with manufacturer warranties up to 30 years, providing long-term protection for your building investment.
