A Practical Guide to Growing Your Spray Foam Insulation Business
Spray foam is one of the most versatile insulation and structural systems available. Whether you’re working on new homes, metal buildings, commercial roofs, or concrete repair, there’s no shortage of customers looking for better performance, energy savings, and long-term protection.
Here’s a practical approach to help you attract steady spray foam insulation leads and build your business across multiple spray foam applications — not just the usual attics and basements.
Think Beyond the Attic — Expand Into High-Value Foam Applications
Here are a few application methods for spray foam insulation that will allow you to expand your services.
Spray Foam Roofing (SPF Roof Systems)
- Flat commercial roofs, mobile homes, warehouses, churches, schools
- Excellent for energy efficiency and leak prevention
- Great add-on if you already offer closed-cell foam
💡 Pro tip: Contact roofing contractors who don’t offer foam — many would sub it out to you.
Slabjacking / Foam Concrete Lifting
- Uses high-density polyurethane foam to lift sidewalks, driveways, porches, garage floors, and warehouse slabs
- Minimal equipment needed beyond your current rig
- Rapid-growing service with excellent profit margins
💡 Bonus: Foam lifting often leads to insulation work under slabs or garage walls.
Exterior Continuous Insulation (CI)
- Used on the outside of buildings to meet new energy codes
- Works for both residential and commercial structures
- Can be applied before siding, stucco, or brick
- Growing in demand as IECC codes tighten
💡 Connect with siding companies or builders doing energy retrofits.
Metal Building & Pole Barn Insulation
- Agricultural buildings, machine sheds, shops, warehouses
- Closed-cell foam solves condensation and heat issues
- One of the fastest jobs to install with great margins
💡 Add value by sealing all seams and penetrations for full vapor control.
Crawlspaces & Rim Joists
- Still one of the best jobs to upsell
- Many HVAC companies will refer you if you educate them
