FM Global 4470 Severe Hail (SH / VSH) & UL 2218 Class 4 Impact Assemblies
Rebuilding a storm-damaged roof in Minneapolis with the exact same vulnerable assembly leaves the asset exposed to the next severe convective storm tracking down I-94, I-35W, I-394, MN-55 (Hiawatha Ave), MN-62 (Crosstown), MN-65 (Central Ave NE), Washington Ave, Hennepin Ave, Lake St, Broadway St NE. During every Minneapolis Commercial Roofing MN restoration in North Loop Warehouse District, Mid-City Industrial Park (NE Minneapolis), Downtown Skyway Core, Seward Industrial Park, North Riverfront Industrial Corridor, Towerside Innovation District (55401, 55402, 55403, 55404, 55405, 55406, 55407, 55408, 55411, 55412, 55413, 55414, 55415, 55416, 55417, 55418, 55419), we engineer upgraded impact-resistant assemblies certified to UL 2218 Class 4 and Factory Mutual FM 4470 Severe Hail (SH) or Very Severe Hail (VSH) standards. By pairing a 1/2-inch high-density gypsum-fiber cover board or 100+ psi HD polyiso board with fleece-backed 80-mil TPO/PVC or 90-mil EPDM membranes, the roof assembly absorbs kinetic energy from 2.0-inch+ hailstones without fracturing the waterproofing ply or crushing the thermal core. Many commercial insurers underwriting properties in Hennepin County offer substantial premium credits and waive cosmetic hail exclusions when FM SH/VSH assemblies are verified by Minneapolis CPED Construction Code Services (Public Service Building, 505 Fourth Ave S).

Frequently Asked Questions: Commercial Hail & Storm Damage Roof Restoration in Minneapolis, MN
How can hail damage a commercial TPO or PVC roof in Minneapolis if there are no visible holes on top?
When a hailstone strikes a single-ply membrane over soft polyiso insulation in Minneapolis, the membrane deflects downward sharply. This stretches the bottom surface of the sheet over the polyester reinforcing scrim, causing microscopic star-shaped fractures on the underside first. Within 12 to 24 months of freeze-thaw cycling in Hennepin County, those fractures propagate through the top weathering layer.
What is the statutory deadline to file a commercial hail damage claim in Minnesota?
Under Minnesota law (Minn. Stat. § 65A.01) and most commercial property policies in Minneapolis, insureds generally have two (2) years from the date of the storm event to initiate legal action or appraisal if a claim is disputed, though policies require prompt notice of loss. Having a HAAG-certified inspection performed in North Loop Warehouse District, Mid-City Industrial Park (NE Minneapolis), Downtown Skyway Core, Seward Industrial Park, North Riverfront Industrial Corridor, Towerside Innovation District immediately after a storm locks in the date of loss.
Will commercial insurance pay to upgrade our Minneapolis roof to the 2024 R-30 insulation code?
If your commercial policy includes Ordinance or Law (Building Code Upgrade) coverage, the insurer is obligated to pay for code-mandated upgrades enforced by Minneapolis CPED Construction Code Services (Public Service Building, 505 Fourth Ave S)—such as R-30ci insulation, tapered crickets, and ANSI/SPRI ES-1 edge metal—whenever a storm-damaged roof replacement triggers municipal code compliance.
