Looking to cut down on energy bills and boost indoor comfort? The answer may lie just above your head—your roof. With Spray Foam Insulation Kits, insulating your roof can become a simple and rewarding DIY project that brings long-term savings.
Why Spray Foam Roof Insulation Works
Spray foam insulation is applied as a liquid and expands to fill every crack and gap. It’s especially effective for roofs, where air leaks can cause significant energy loss. ixirpro’s spray foam solution offers a durable, long-lasting barrier that seals your home against heat, moisture, and drafts. When properly applied, it can last up to 30 years.
Beyond performance, this insulation method reinforces the structural integrity of your roof, shielding your home from weather and external elements.
Save More with a DIY Project
Using the DIY Spray Foam Kit, homeowners can easily tackle roof insulation themselves. This eliminates the high cost of hiring professionals, which typically ranges between $2000 and $3500.
Our kit is user-friendly—no special tools or technical experience needed. Just follow the step-by-step guide and apply the foam to metal, flat, or pitched roofs, garages, or sheds.

Cost Breakdown: DIY vs. Professional
The average cost of professional spray foam roof insulation ranges from $2000 to $3500. On the other hand, with Ixirpro's DIY kits, the average cost drops to around $1.10–$1.20 per square foot. That’s a significant difference for homeowners looking to save.
Roof insulation cost varies depending on roof size, foam thickness, and foam type. Investing in a DIY kit offers one of the best returns for energy-efficient upgrades.
R-Value Explained: How Much Do You Need?
R-value is the measure of thermal resistance. The higher the R-value, the better the insulation performance. Spray foam comes in two types:
- Closed-cell foam: R-5.66 per inch (ixirpro)
- Open-cell foam: about R-3.5 per inch
For example, if local building codes require a minimum of R-25 for roof insulation, you would need about 4.5 inches of closed-cell foam at R-5.66 per inch, or roughly 7 inches of open-cell.
Frequently Asked Questions
What’s the best roof insulation?
Spray foam insulation offers a superior R-value and better air sealing compared to traditional insulation.
Can I apply it myself?
Absolutely. Ixirpro DIY kits are designed for homeowners with no prior insulation experience.
How long does spray foam insulation last?
Ixirpro spray foam insulation can last up to 30 years without needing replacement.
What types of roofs is it suitable for?
Ixirpro spray foam works on flat, pitched, and metal roofs, as well as garages, attics, and sheds.
Is it safe for indoor air quality?
Yes, when properly applied, spray foam insulation improves indoor air quality and is safe for those with asthma or allergies.
Should you insulate under a metal roof?
Yes. Insulating the underside of a metal roof improves energy efficiency, prevents condensation forming on the cold metal, and makes the space below far more comfortable in both summer heat and winter cold.
Do metal roofs need a vapour barrier?
Yes. Without one, warm indoor air meets the cold metal deck and condenses, which leads to damp insulation and mould. Closed-cell spray foam acts as its own vapour barrier at sufficient thickness, which is why it suits metal roofs particularly well.
How do you stop condensation on a roof?
Condensation forms where moist indoor air reaches a cold surface. Spray foam stops it at the source by sealing the air leaks that carry that moisture upward. Pair it with adequate ventilation for the best result.
What is the minimum thickness for roof insulation?
One inch (2.5 cm) is the practical minimum for closed-cell foam on a roof. Two inches (5 cm) gives a meaningfully higher R-value and is the better choice in cold climates or where the roof deck is the main heat-loss path.
