Spray Foam Roof Deck Problems

While this does not pose a health concern it is a concern for surrounding property.

Spray foam roof deck problems.

The problem with that solution though is that it violates the building code for an attic with exposed spray foam insulation. Rooftop hvac units must be covered and the entire hvac system shut down during spraying. Fumes emitted during the spraying process present a potential hazard to employees or customers in or around the building. Spf s key ingredient isocyanate is hazardous when inhaled or when it comes into contact with the skin.

As one of the most quickly adopted high performance building materials available in the market there has been a lot of noise made about spray foam insulation and its performance ability. Spray foam causes moisture problems in the roof line. At west roofing systems we take extra care to prevent overspray. Punctures and damage should be caught early to prevent leaking into the facility.

Spray on roofs can also be levelled out more easily reducing the collection of water in ponds. Yeah you probably still breathed some of it but not as much as you will now with spray foam on the roof deck. To get the best performance out of spray foam insulation you must cover the roof rafters and surrounding areas as thoroughly as possible. This is because the top floor ceiling is no longer the air barrier for the house the spray foam at the roof deck underside in the attic is the air barrier.

The foam will also contract and expand depending on the weather which again reduces cracks. It s ok to leave the foam exposed in an attic if you cover it with an ignition barrier. If you directly condition the attic however now you need a thermal barrier and no builder s gonna do that. Since the spf roof is installed by a spray application there is a risk of the wind carrying overspray onto surrounding cars and other surfaces.

By encapsulating the attic and leaving the old insulation up there that filth is in your conditioned space. Even small gaps can allow the passage of warm air through the foam rendering the foam all but useless as an insulator. With a spray on roof you can fill gaps seams and cracks in your existing roof construction giving you even more protection. Your indoor air quality may get worse.

Spf roofing systems should be regularly inspected whether there is known damage or not especially after severe weather events that could cause damage such as hail storms tornadoes and hurricanes. You may have odor problems.
