These home owners in Enfield, CT had us come out because they had ice dams last year and didn't want them to damage their home. Ice damming occurs when the heat that you pay for rises up into your attic and heat the bottom of the roof deck to above 32 degrees. Then the snow melts and runs down the roof until it gets to the end where there is no more heat loss heat up the roof and it re-freezes. This can lead to very expensive water damage that nobody wants to deal with. To fix this problem it makes sense to seal the attic up so no more of the hot air we pay for can escape into the attic. One of the things we have to do is seal up the can lights in the home. One can light lets 10 cubic feet of air escape a minute! Most home don't just have one light, some have 10 or more! To fix this we go around and put or tite' shell can light covers on. These are made of rock wool so it is fire retardant making it safe to put over the light. Then we air seal that cover to the sheet rock so no air can pass. This home is now one step closer to to getting rid of the ice dams!
