Spray foam solution seals elementary school roof ahead of tight deadline

A recent school roof overhaul highlights safety, sustainability and seamless execution by a top-rated contractor. 

When South Park Elementary School faced the daunting task of replacing its roof in time for the new school year, Strong Contractors Inc. stepped up to deliver — with precision, speed and environmental foresight. 

The Colorado-based commercial roofing company, led on this project by Matteo Mazzullo-Revel, tackled a more than 40,000-square-foot roof overhaul at the school’s 3100 Hollywood Dr. location using spray polyurethane foam (SPF). The complex installation, completed in just 17 days, showcases the firm’s ability to solve logistical challenges under pressure — especially with multiple HVAC penetrations complicating the layout. 

“Every HVAC unit had to be meticulously masked to avoid overspray,” said Mazzullo-Revel, a SPFA PCP Certified Master Installer. The intricate setup demanded both technical expertise and tight coordination, made tougher by a hard deadline to finish before students returned. 

The project employed Gaco Low GWP F2780 foam, GacoFlex S2000 silicone and anti-slip #6 white granules. These materials formed a monolithic system — a seamless roofing approach that enhances durability, particularly in environments riddled with roof penetrations like vents and HVAC mounts. The granules also aid in ongoing maintenance, offering safe footing for technicians accessing the roof. 

Beyond the technical aspects, Strong Contractors ensured compliance with OSHA fall protection standards and brought in a third-party safety consultant, resulting in zero incidents — no small feat on a job of this size and scope. 

Environmentally, the SPF system offered a major plus: it allowed the team to build over the existing roof, diverting tons of waste from local landfills — an increasingly important consideration in public works projects. 

This isn’t Strong Contractors’ first time in the spotlight. The firm, co-owned by a husband-and-wife team, has earned recognition from Gaco as a top applicator in 2023 and 2024 and landed on the Inc. 5000 list for its rapid growth. Their past work includes high-profile government and education projects across Colorado, including an expansive slate of roofing for Pueblo School District 60 in 2024.
