Flat roofing is what separates experienced contractors from general roofers. The materials are different, the installation methods are different, and the failure points are different. Sandown Roofing & Maintenance has been installing flat roofs in Sandown for 18 years. We know what works and what doesn't in NH's climate.
Our Flat Roofing Process
Membrane Assessment
Our inspector checks every detail: ponding areas, seam separations, flashing failures, clogged drains, UV degradation, and blistering. Core samples test insulation moisture content. You get photos and an honest assessment.
System Recommendation
Based on inspection findings, we recommend the right solution: targeted repair, a coating system, or full replacement. Each option is priced with material specs, warranty terms, and expected lifespan.
Professional Installation
Insulation board cut and installed with staggered joints. Membrane installed over insulation per manufacturer specs. All penetrations (pipes, vents, HVAC curbs) receive custom-fabricated flashing. Drains and scuppers cleared and properly connected to the new membrane system.
Completion & Warranty
Your flat roof gets a completion package: installation documentation, warranty certificates, drainage verification, and maintenance recommendations. We stand behind every flat roof we install in Sandown.

Why Choose Sandown Roofing & Maintenance for Flat Roofing?
Maintenance Programs
Semi-annual flat roof inspections keep your warranty valid and catch problems early. Drain clearing, seam checks, and flashing inspection, all documented.
All Flat Roof Systems
TPO, EPDM, PVC, modified bitumen, built-up roofing, and coatings. We install the right system for your building, not whatever we have on the truck.
Specialized Flat Roof Crew
Flat roofing requires different skills and equipment than sloped roofing. Our flat roof crew does this work every week, hot-air welders, torch kits, and adhesive systems are their daily tools.
Core Sampling & Testing
Before recommending replacement or coating, we core sample the roof to check insulation moisture. Waterlogged insulation means tear-off. Dry insulation means options.
About Our Sandown Flat Roofing Services
PVC membrane is the only flat roofing material that resists animal fats and chemical exposure from rooftop grease exhaust. If you own a restaurant or commercial kitchen in Sandown, PVC is the right choice. TPO and EPDM will deteriorate when exposed to kitchen grease venting.
Roof coatings can extend the life of an existing flat roof by 10-15 years for a fraction of replacement cost. Silicone coatings over TPO, EPDM, or metal work well when the existing membrane is still in decent condition. We core sample and moisture scan to make sure coating is the right call before recommending it.
