Replace any missing or torn insulation in your home before winter weather arrives. Keeping your attic from getting too warm is a waste of your home heating budget. In addition, a warm attic melts snow off the roof directly above the attic but not on the eaves, creating dangerous ice buildup that can damage gutters or break loose and injure someone below.
Open the attic vents to allow cool air to circulate. Clear away any debris that may be blocking the vents, and replace venting that might be inadequate. Keeping the attic, and therefore the tin roof, cooler reduces the effects of ice buildup at the eaves. If you have an older home, consider calling in professionals to upgrade the ventilation system to benefit you in both winter and summer.
Seal the metal roof with a slick coating designed to shed snow and ice before they can build up. Contact a professional roofing company with experience in tin and other metal roof installation to apply the sealant.
Install a heating system specifically designed for metal roofing. Contact a professional roofing company about retrofitting under-metal heating coils that warm the roof and prevent snow and ice from accumulating.
