Bott Roofing’s experience in air circulation and insulation can help you find the right solution for your particular roof situation, keeping the attic cooler and dryer, even in hot Chicago summers. Spray foam insulation is the best way to control condensation in tricky attic spaces.
In general, the house leaks warm humidified air into the attic, which makes for happy mold if the space is improperly ventilated or insulated. Spraying high-quality closed cell foam directly onto the plywood interior of the roof creates an air-tight barrier to mold and prevents condensation from forming. Spray foam insulation can also be used to waterproof and insulate metal HVAC ducts or standing metal seam roofs, where leaks commonly occur.
