Anytime of the year is a good time to insulate with Spray Foam Insulation; but now’s the time to get a jump on the cold weather by eliminating the potential of ice dams forming on your roof by using Spray Foam Insulation on the underside of your roof deck.
When warmed air rises through your ceilings and hits the cold underside of the roof deck condensation forms and then freezes causing ice to form. You can see evidence of this by looking at the nails protruding through your roof deck which will be covered in ice or frost. This same warmed air melts the snow or ice just at roofline and that water runs down to the eaves of the roof and refreezes causing ice to form. This cycle happens over and over and eventually an ice dam forms which can back up and cause thousands of dollars in damage to your home.
By Insulating the underside of the roof deck with Spray Foam Insulation; you stop that freeze – thaw cycle completely. Think of it as putting a hat on your head keeping all the heat in!
