When this system may fit

Is this the right assembly?

  • Added insulation and air-sealing are wanted during restoration
  • Drainage needs correcting by adding slope
  • A seamless recover of a complex roof is preferred
  • The existing deck can be prepared to receive foam

These are indicators, not a specification. Suitability is confirmed by a project review.

Existing condition

What we assess first

  • Deck soundness and moisture
  • Existing roof suitability for foam
  • Weather windows for foam and coating
  • Drainage goals and slope build
Preparation requirements
  • Confirm the substrate is clean, sound and dry
  • Remove wet or failed materials
  • Prime where required
  • Verify acceptable weather for foam application
Critical details
  • Penetrations and curbs
  • Terminations and edges
  • Transitions and drains
  • Coating of all foam within the recoat window
Application sequence

How it goes together

Prepare

Clean and prepare the deck; correct wet or failed areas.

Apply foam

Spray foam to the specified thickness, building slope as needed.

Coat

Apply the protective coating within the recoat window.

Surface

Broadcast aggregate where specified for wear.

Approved system build. The specific products, film builds, coverage rates, cure and recoat times and the qualified build-up for the Spray-Foam Roofing System are confirmed by the current specification and a project review. We publish these values only where supported by the approved product documents — request the specification for your project below.
Performance

What it delivers

  • Adds insulation and air-sealing
  • Builds positive drainage slope
  • Seamless and self-flashing
Limitations & considerations

Where to take care

  • Foam must be coated within its recoat window
  • Highly weather- and moisture-sensitive application
  • Requires trained crews and equipment
Weather & cure conditions
  • Foam and coating require suitable temperature, wind and humidity
  • Protect uncoated foam from UV and moisture
  • Observe recoat windows strictly
Quality-control checklist
  • Substrate dryness verified
  • Foam thickness and slope checked
  • Recoat window observed
  • Coating coverage verified
