Coating Systems
Commercial Roof Coating Options for Norfolk
Foam is one of five systems. Compare it with the coatings we apply without foam.
Metal Roof Coating
- Best on: steel shops, plants, and storage buildings
- Watch for: rust holes and wet insulation first
Silicone Roof Coating
- Best on: low-slope roofs where rain sits for days
- Watch for: recoats must stay silicone
Acrylic Roof Coating
- Best on: sloped panels that drain within a day
- Watch for: needs warm, dry days to cure
Spray Foam Roofing
- Best on: roofs that need added insulation
- Watch for: calm, dry weather and a topcoat
Shingle Roof Coating
- Best on: intact shingles on offices and churches
- Watch for: curled or missing tabs first
Who Gains
Benefits of Coating Your Roof
Foam is a coating system with insulation built in, so the gains run past leak control.
Owner
- The old roof stays on, so there is no tear-off and disposal
- Added insulation stays with the building
- Low spots can be built up so water drains
Facility Manager
- One continuous layer leaves no laps to reseal later
- Upkeep becomes a scheduled topcoat renewal
- Odd shapes around curbs and parapets get covered easily
Tenants And Staff
- Steadier temperatures in shops and storage under the roof
- Quieter rain and hail on the roof deck
- Fewer drips from laps over work areas

Work Sequence
How Norfolk Spray Foam Roofing Is Installed
Foam goes down fast, so the days before it are about dryness and protection.
- 1On The Roof
Inspect Your Roof
We core or probe for wet insulation, check that the deck is firm, and note every vent, intake, and curb that needs shielding from overspray.
- 2Around The Building
Remove Wet Material And Mask
Soaked insulation comes out and gets replaced, then air intakes, vehicles, and walls near the roof edge are covered before spraying.
- 3On The Roof
Spray The Foam
Foam is sprayed in lifts on a dry, calm day to the planned thickness, with extra build in low areas to push water to the drains.
- 4On The Roof
Topcoat The Same Week
A silicone or acrylic topcoat goes on soon after, since bare foam breaks down in sunlight, and we check its thickness before we leave.

Questions
Top Spray Foam Roofing Questions in Norfolk
Answers for owners pricing a foam roof.
Leaks And Fit
Will spray foam stop leaks in a metal roof?
Yes, by covering laps, screws, and seams with one continuous layer that fills gaps you would otherwise seal one at a time. The steel has to be clean, dry, and firm for the foam to bond, wet insulation underneath comes out first, and a protective coating finishes the system.
Can foam go on during a Nebraska winter?
No. Product labels set minimum air and surface temperatures and require a dry roof, and frost, dew, and snow block adhesion. We schedule foam for the warmer months and use winter for inspections and planning, so the roof is ready when the weather allows.
Cost
What is spray foam roofing cost per square foot?
It depends on foam thickness, the shape of the existing roof, and the topcoat. Thicker foam adds insulation and material. Removing wet insulation, new edge metal, and access also move the number. For planning, coating work runs about $2.50 to $4 per square foot and replacement about $5 to $8.
Upkeep
What is spray foam roof recoating?
Recoating renews the protective topcoat on an existing foam roof. Sunlight breaks down foam, and the topcoat wears thin over the years. We clean the surface, repair damaged foam, and apply fresh silicone or acrylic so the foam underneath stays protected.
What are the spray foam roofing pros and cons?
On the plus side, foam adds insulation, seals odd roof shapes, and forms one layer with no laps, and it can go over many existing metal roofs. On the other side, it needs dry, calm weather to install, the topcoat needs periodic renewal, and hail can puncture a surface that then degrades in sun.
