What You Get With Sure.
-
Sure Roofing installs flat roof systems built to withstand San Francisco's coastal climate of fog, wind, and rain. Our commercial services include torch-down and modified bitumen roof replacements designed for long-lasting durability, as well as silicone-based elastomeric roof upgrades that add a seamless protective layer.
Commercial flat roofs face challenges that residential roofs do not. HVAC units, exhaust vents, skylights and drainage systems create penetration points that require precise sealing. Foot traffic from maintenance crews can cause punctures over time. San Francisco's daily temperature swings between morning fog and afternoon sun stress roofing materials through constant expansion and contraction.
Sure Roofing addresses these demands with roofing systems suited for commercial use and proper sealing around every rooftop penetration.
-
The Sure Secure Hybrid (SSH) is Sure Roofing's signature flat roof system, developed by Richard Choy over decades of flat roof experience in San Francisco. This assembly combines a heat-installed modified bitumen primary roof with a proprietary fluid-applied protective system.
The Sure Secure Hybrid solves a core vulnerability in traditional flat roofing by permanently sealing and shading the modified bitumen base from sunlight. Traditional tar and gravel roofs and standard modified bitumen systems rely on petroleum asphalt for waterproofing, which loses adhesion and flexibility once UV rays break down the material. The SSH's reflective topcoat minimizes absorption of both UV and infrared rays, keeping the base roof cooler, softer and more pliable for decades. The system comes with up to a 25-year NDL warranty.
-
Sure Roofing seals and protects rooftop equipment throughout every commercial project, keeping HVAC systems, solar panels, security devices and fire alarm systems operational while work is completed. Every penetration point is addressed individually and crews coordinate around your building's schedule.
Sure Roofing's detail-oriented approach includes:
Sure Roofing seals carefully around HVAC units, security systems and fire alarm penetrations to prevent leaks at every rooftop penetration point.
Sure Roofing protects rooftop equipment from debris and damage throughout each commercial project.
Crew scheduling at Sure Roofing is coordinated with building operations to minimize disruption to your daily operations.
Penetration points around rooftop equipment are among the most common sources of commercial roof leaks. Proper flashing and sealing at these locations is critical to long-term roof performance.
-
Flat and low-slope roofs can often be restored without full replacement through the application of elastomeric coatings. Sure Roofing offers protective coating systems including aluminized paint, acrylic coatings and silicone coatings.
These coatings create a seamless, weather-resistant barrier that helps reduce leaks, improve reflectivity and protect against San Francisco's coastal climate. For property owners seeking long-term value, Sure Roofing's silicone-based coatings come with a 25-year NDL warranty, making them a cost-effective alternative to full roof replacement.
