Andover MN Commercial Flat Roofing Replacement Project
Commercial properties in Minnesota face an unforgiving architectural challenge: enduring extreme seasonal temperature swings, from freezing, snow-laden winters to intense summer heat waves. When the flat roof system in Andover, MN required a comprehensive update, Englund Roofing & Sheet Metal was selected to deliver a commercial roof replacement solution focused on long-term durability, structural integrity, and maximized energy efficiency.
As dedicated Flat Roofing Specialists, our objective was clear: eliminate the compounding liabilities of an aging hot roof assembly and replace it with a modern, high-performance synthetic rubber membrane. This case study details the precise engineering, premium materials, and meticulous execution built into this commercial project to safeguard the facility for decades to come.
How We Replaced the Commercial Flat Roof in Andover, MN
- Roof Preparation & Strategic Tear-Off – Every high-performing roof relies completely on the quality of its substrate. To build a system that lasts for decades, our crews initiated a precise skim tear-off of the existing hot-applied, built-up roofing system. Instead of a blind tear-down that risks exposing the building interior to unpredictable Minnesota weather, we carefully stripped away the degraded top layers down to the primary core insulation. This method allows our technicians to perform a structural inspection across the entire roof deck. Any underlying insulation sections displaying signs of moisture infiltration, compression, or compromised structural integrity are cut out and replaced with fresh, dry stock. This establishes an unyielding, uniform foundation for the new roof.
- High-Performance Insulation Upgrades – Energy code compliance is only the baseline; true commercial value comes from lowering operational HVAC costs. To achieve this, Englund Roofing & Sheet Metal integrated a new layer of 2.6” polyisocyanurate (ISO) rigid insulation directly over the inspected substrate. Polyisocyanurate is widely recognized as the industry standard for flat roof thermal resistance. By pairing this new 2.6″ layer with the viable existing substrate, we elevated the building’s total assembly to an approximate R-30 insulation value. This dramatic drop in thermal transfer prevents costly heat loss during freezing winter months and reduces the cooling load during hot summers, providing immediate and permanent energy efficiency gains.
- Fully Adhered 60 Mil EPDM Installation – With the insulation foundation secured, we deployed a premium 60 mil EPDM (Ethylene Propylene Diene Monomer) synthetic rubber membrane. Known for its incredible tensile strength and elasticity, EPDM handles the rapid expansion and contraction caused by local weather shifts without cracking or splitting. The membrane is fully adhered to the substrate using advanced commercial adhesives. This method eliminates the mechanical fasteners that can create micro-thermal bridges and offers superior wind (uplift) resistance. Special emphasis is placed on detail work: all seams, perimeter edges, structural penetrations (such as HVAC curbs and vents), and transitions are sealed using heavy-duty flashing materials engineered to meet strict manufacturer specifications.
- Rigorous Quality Assurance & 20-Year Warranty – A premium roofing system is only as good as the accountability behind it. Every phase of this installation was completed in strict accordance with the manufacturer’s technical specifications. Upon completion, the project qualifies for a comprehensive 20-year manufacturer warranty. This provides the property owners of Andover Station North with long-term capital protection and absolute peace of mind against leaks and material defects.
