Wet Insulation Under Old Panels
- You See
- Soft spots and musty smells near ceiling stains.
- What It Means
- Foam sealed over wet material holds that water in. Wet areas are cut out and dried before any foam is sprayed.

Fit Check
Is Your Merrillville Roof a Candidate for Spray Foam Roofing?
Merrillville spray foam roofing works on roofs that are dry and firm underneath. These five checks come before any foam goes down.
| Roof Detail | Ready For Foam | Fix Or Rethink |
|---|---|---|
| Deck | Firm steel or concrete deck | Rotted or sagging sections |
| Moisture | Dry insulation and substrate | Wet insulation left in place |
| Existing Roof | Metal panels or a firm built-up roof | Loose gravel or a blistered membrane |
| Rooftop Air Intakes | Units that can pause for spraying | Intakes that must run nonstop |
| Drainage | Low spots to build up with foam | Drains that need relocating |
Fixed First
Merrillville Spray Foam Roofing: Problems Solved Before Spraying
Foam bonds to whatever it is sprayed on, so these four conditions are dealt with first.
Corrosion
Panels Rusted Through
- You See
- Daylight showing through pinholes from inside the building.
- What It Means
- Holes larger than foam can bridge get new steel first. Smaller rusted areas are primed so foam bonds to a clean surface.
Overspray Risk
Air Intakes and Parked Cars
- You See
- Rooftop units and a parking lot right beside the roof edge.
- What It Means
- Wind carries fine foam particles. Intakes are shut down and covered, and spraying stops when wind rises past the product limit.
Snow
Heat Loss Melting Snow From Below
- You See
- Icicles at the eaves and ice building up at the drains.
- What It Means
- Warm air escaping through the roof melts snow that refreezes at the cold edges. A continuous foam layer slows that heat loss.
Your Options
Commercial Roof Coating Options for Merrillville
Foam work comes in three forms, set by what is on the roof today.
Foam Over Metal Panels
Leaking screw-down steel gets foam sprayed right over the ribs, then a coating, with the panels left in place.
Foam Over a Built-Up Roof
Firm, dry built-up or modified roofs can take foam on top once loose gravel and blisters are removed.
Foam to Fix Low Spots
Areas that pond get extra foam thickness to build slope toward the drains before the topcoat.

Benefits of Coating Your Roof
The roof before foam, and the same roof once foam and coating are on.
Before Coating
- Hundreds of screws and laps, each a leak path
- Heat escaping and melting snow into ice at the edges
- Low spots holding water by the drains
- Drips over the work floor after storms
After Coating
- One continuous foam layer over screws and laps
- Continuous insulation slowing heat loss in winter
- Foam built up to move water toward drains
- A protective coating keeping sunlight off the foam
Before You Call
Ice Building Up at the Roof Drains?
Ice at the drains often means heat is escaping through the roof. Tell us what you see from inside and out, and the roof walk checks the deck and insulation.

How It Goes
How Spray Foam Roofing Is Installed in Merrillville
Foam is sprayed in stages, with weather and wind checked at each one.
- Findings
Inspect Your Roof
The deck, insulation, panels, and drains get checked, and moisture readings mark any wet areas. Intakes and nearby parking are noted for overspray control.
- Repairs
Repair and Dry the Base
Wet insulation comes out, rusted-through steel is replaced, and failed curbs are rebuilt so foam goes over a firm, dry surface.
- Protect
Protect Intakes and Edges
Rooftop units are shut down and covered, and edges near parked cars get screens. Spraying waits for calm air.
- Spray
Spray the Foam in Lifts
Foam goes on in passes until it reaches the planned thickness, with extra build-up in low spots to push water toward the drains.
- Coat
Coat the Foam Surface
A protective coating goes over the foam soon after spraying, at the thickness the system calls for, with granules added where people walk.

Spray Foam Roofing Questions From Merrillville Owners
Winter insulation, leaks, service life, cost, hail, and foot traffic on foam roofs.
Does Spray Foam Roof Insulation in Winter Make a Difference?
Yes. Foam lays a continuous insulating layer over the deck with no breaks at screws or seams, which slows heat loss through the roof and seals air leaks there too. With less heat escaping, less snow melts from below and refreezes at the edges and drains.
Will Spray Foam Stop Leaks in a Metal Roof?
Foam covers screws, seams, and laps in one unbroken layer, which closes most metal roof leaks. Rusted-through panels, failed curbs, broken flashing, and wet insulation are repaired before spraying. A protective coating then goes over the foam, since sunlight breaks down a bare foam surface.
How Long Does a Spray Foam Roof Last?
Decades, when the protective topcoat is kept up and renewed on schedule. The foam underneath holds up well; it is the coating that wears. Foam thickness, coating thickness, hail, and how quickly damage gets patched decide how long yours goes.
What Is the Spray Foam Roofing Cost per Square Foot?
Foam pricing comes after the inspection and is weighed against the published ranges of about $2.50 to $4.00 per square foot for coating and about $5 to $8 per square foot for replacement. Foam thickness, the topcoat, metal prep, roof size, and access set the figure.
Can Spring Hail Damage a Foam Roof?
Hail can dent or break the protective coating and expose the foam beneath. Dents are mostly cosmetic, but breaks let water and sunlight in. After a storm we check the surface, cut out damaged foam, refill it, and recoat those spots.
Is a Foam Roof Safe to Walk On for Unit Service?
Coated foam handles normal service foot traffic. Walkway pads or granules embedded in the topcoat along the routes to rooftop units spread the load and keep the coating from wearing through where techs walk most.
