Commercial Roofing Foam

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 Plane

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.

Why Foam

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}}

What We Insulate

Commercial roof decks of every type.

Interior roof-deck spray foam for the commercial and industrial buildings across Minnesota. Common projects include:

Metal Roof Decks

Stop the sweat

Seals warm air off the cold steel to stop condensation
Ends the dripping that damages inventory and equipment
Bonds to the deck and stays put for the long haul

Flat & Low-Slope Roofs

Big surfaces, big returns

Insulates the large flat roof planes common to commercial buildings
Cuts heat gain in summer and heat loss in winter
Air-seals penetrations and framing across the deck

Shops & Ag Roofs

Post-frame and steel

Roof-deck foam for pole barns and steel shops
Condensation control that protects what is stored below
Makes the building practical to heat

Warehouse Roofs

Large-envelope roof planes

Seals and insulates expansive roof decks
Helps hold a stable interior temperature
Foam matched to the roof structure and use
How It Works

Our commercial roofing foam process.

STEP 01

Assess the Deck

We inspect the roof deck and framing, review the building's use, and spec the right foam and thickness for the roof plane.

STEP 02

Prep & Protect

We mask off the interior, protect equipment and inventory, and prepare the deck for a clean, durable bond.

STEP 03

Spray the Roof Plane

We apply foam to the underside of the deck and framing, air-sealing and insulating and stopping condensation in one pass.

STEP 04

Inspect & Clean Up

We verify coverage and thickness, confirm the deck is sealed against moisture, and leave the space clean.

Common Questions

Frequently asked questions.

No. We install interior roof-deck spray foam, which air-seals and insulates the roof plane from inside the building. That is different from the exterior roof membrane or covering that keeps water out. If you need the exterior roof surface replaced or repaired, that is a separate roofing trade, and we will point you in the right direction. {{ROOFING_SCOPE_NOTE}}
