Commercial Roofing Foamin Minnesota
Trust Works air-seals and insulates commercial roof decks across Minnesota with spray foam. We stop condensation on metal decks, cut heat loss and gain through the roof plane, and insulate flat and low-slope commercial roofs from the inside. Fully insured, with 20+ years of experience.
The roof is where a commercial building loses the most.
On a commercial building, the roof is a huge, exposed surface, and it is where a large share of the heat loss, heat gain, and air leakage happens. A poorly insulated roof deck bleeds energy in every season, and on metal and steel decks it also sweats, with warm interior air condensing on the cold deck and dripping into the space below. Sealing and insulating the roof plane is one of the highest-impact moves you can make on a commercial envelope.
Spray foam handles the roof deck by air-sealing and insulating in a single application, closing the gaps and penetrations that let air move and stopping the condensation that damages what is stored or worked on below. It is a direct, durable way to bring a commercial roof up to performance from the inside.
Air-seal and insulate the deck in one pass.
Sprayed to the underside of the roof deck and into the roof framing, closed-cell spray foam bonds to the deck and cures into a rigid, air-tight, moisture-resistant layer. On a metal deck it stops condensation by keeping warm interior air off the cold steel, and its high R-value per inch delivers strong insulation in the depth the roof structure allows.
For larger or less condensation-critical roof areas, open-cell foam offers a cost-effective air seal. We assess the roof deck and how the building is used, then spec the right foam and thickness so the roof performs without over-building. This is interior roof-deck insulation; for the exterior roof membrane and covering itself, we will point you to the right roofing trade. {{ROOFING_SCOPE_NOTE}}
