SPF Insulation & Roofing
Cut energy costs by 30-50% with professional spray foam solutions.
Spray polyurethane foam (SPF) delivers superior insulation performance and roofing protection through our advanced spray-in-place technology. Whether you're building new, renovating, or need a commercial roofing solution, SPF provides unmatched energy efficiency and structural benefits.


If it’s good enough for NASA...
Since the Apollo missions of the 1960s, NASA has been using SPF to protect its multi-million-dollar rockets and valuable human cargo from the most extreme conditions in the universe.
We bring that same advanced thermal technology down to Earth—sealing and insulating your home or commercial property against the extreme temperatures, storms, and moisture of the Pacific Northwest. Because the same insulation that survives rocket launches and interplanetary travel — with forces up to 3 g’s and thermal swings from –423 °F to +260 °F — can handle your roof.
Spray Foam Insulation:
The Ultimate Thermal Barrier
SPF insulation works smarter than traditional insulation. It expands on application to seal cracks, gaps, and penetrations—helping keep conditioned air inside and outside air where it belongs.
For residential and commercial projects alike, that means lower energy costs, improved comfort, and better protection against moisture and temperature extremes—all with a solution designed to perform for decades.

Spray Foam Roofing: Unmatched Efficiency, Protection, and Value
Water intrusion typically occurs at seams, penetrations, and flashings. SPF eliminates these vulnerabilities by creating a continuous, self-flashing surface that adheres completely to your existing roof.
The foam flows around HVAC units, pipes, vents, and other rooftop equipment, sealing potential entry points without mechanical fasteners or adhesives.


"You pick — either insulation or a roof system — and I’ll give you the other for free."
"Years ago, while speaking with a general contractor and building owner about a new roof system, the owner mentioned that money was tight with many phases of construction still ahead. My response was simple: 'You pick — either insulation or a roof system — and I’ll give you the other for free.' Because with SPF, the system is exactly that: a roof system that insulates."
— Dave Cook, President of Hoag Roofing
What makes SPF a superior option?
Creates an Airtight Seal
SPF expands into cracks and gaps, creating an airtight seal against dust, pollen, and other airborne pollutants.
Superior Thermal Performance
SPF delivers a high R-value, helping prevent heat transfer through your roof assembly.
Structural Strength
Closed-cell spray foam adds rigidity and strength to roof decks and walls.
Longevity & Durability
Properly applied SPF can last decades, reducing the need for frequent replacement.
Lower Heating & Cooling Cost
SPF can significantly reduce HVAC demand — helping cut energy costs and stabilize indoor temperatures.
Moisture Resistance
Closed-cell spray foam resists water absorption and can act as a secondary moisture barrier, reducing mold.

Professional Installation Makes the Difference
As the only roofing company in the region that offers SPF, our trained, certified technicians use professional-grade spray equipment and follow strict application protocols to ensure optimal performance. Comprehensive warranty coverage ensures your investment remains protected for years to come.
