That’s why NASA uses it in space to insulate against -425°F temperatures!

2. Spray Foam has no joints, no cracks. No heat loss through joints as in board stock.

Conditions such as this, in which the fastener plates melt the snow, visually demonstrate the heat loss that is a known entity to roof installers and knowledgeable roofing professionals. – Thomas Hutchinson

Here’s what one expert has written about mechanically fastened roofs: “Many mechanically attached roofs, incorrectly promoted and sold as energy-saving systems, were actually energy pigs. One only needed to walk a mechanically attached roof with a few inches of snow on it to see the heat loss occurring. It doesn’t take scientific studies and long-winded scenarios to prove this—just get up on the roof and see it.”

According to this expert, choosing mechanically fastened board stock insulation roof insulation system with its cracks, seams, and metal fasteners can routinely increase your energy bills by 30% and put undue strain on your heating/cooling equipment!

3. Spray foam insulation is self-adhering, with no heat loss through mechanical fasteners.

Note too that the joints in the board stock are also visible as another source of heat loss. (From the study Three-Dimensional Heat Transfer Analysis of Metal Fasteners in Roofing Assemblies)

How much heat loss are we talking here? Up to a whopping 48%! Here’s what a 2016 study concluded: “The effect of Metal Fasteners is not negligible as considered by general standards. In fact, they are seen to cause as much as 48% change in the effective R-Value of the (insulation) assembly with very high density of metal fasteners.”

That means that to meet today’s building code requirement of R35 on a commercial roof you would need to install 48% more insulation, or R52! Wouldn’t it be easier and much less costly to just use spray foam?

4. Only spray foam insulation is an air barrier, sealing your roof and preventing preventing costly air infiltration or exfiltration.

Note this quote from Energy Education: “Air infiltration and exfiltration will impact a building’s energy costs. Infiltration also affects indoor air quality because it introduces pollutants, allergens, and microbes into the building. It can also result in moisture accumulation in the building envelope because airflow carries with it rainwater and water vapor (see moisture intrusion).”

5. Spray foam is a “smart” vapor barrier, doing the right job in both heating and air conditioning seasons.

You avoid condensation, humidity, and mold issues summer and winter. How important is that?

Note these comments from Mike Holmes: “What makes spray foam so effective? It controls moisture—that’s the big one. Forty per cent of heat loss is due to air movement, but the other 60 per cent is related to moisture. Heat moves with moisture. The warmer the air, the more moisture it can hold. Cold air means less moisture, which is why your hands and lips get dry in the winter when you go outside. But spray foam creates a barrier to stop moisture movement, which helps stop heat loss.”

So what’s the conclusion? Insulating your commercial flat roof with anything but a spray foam roofing system can be a decision that could cost you dearly now, in installation costs, and for years to come in increased energy costs!
