Ice Damming

Ice dams are the build-up of ice at the eaves and valleys of roofs, and in some winter seasons develop significant issues. Inadequate attic insulation or attic ventilation can trigger roof snow to move and melt down to the eaves, where the roof surface area is cooler and the melting snow adheres the roof. Subsequent melting triggers water to swimming pool behind this dam and often the water leaks in between the shingle layers, moistening the roof deck and potentially the walls and ceilings listed below.
Interior damage brought on by ice dam. What To Do?
1. Thoroughly seal all ceiling penetrations such as lights to keep warm, wet air out of the attic.
Guarantee appropriate attic ventilation of around 1 sq.ft.
Guarantee that soffit vents are not obstructed by insulation. If blown-in insulation tends to wander into the eaves, utilize 1/4inch plywood or paneling to develop barriers in between the rafters. Pre-fabricated barriers are likewise offered.
4. In brand-new houses, roofing felt is used from the edge of the roof to a point not less than 12″ inside the inner face of the outside wall. In some areas this eaves security should go 10 or 12 feet up the roof (specifically on low-sloped roofs) and the complete length of valleys.
5. Attempt roof heating system cable televisions as an interim step, till it’s time for brand-new roofing products. Do not forget to explain the issue locations to your roofer, so he can offer appropriate security products.
An advice: Roofing is an obviously “simple adequate” task for anybody, however there are lots of great points that might leave the do-it-yourselfer. An expert roofer can be your friend!

Inadequate attic insulation or attic ventilation can trigger roof snow to move and melt down to the eaves, where the roof surface area is cooler and the melting snow freezes to the roof. Subsequent melting triggers water to swimming pool behind this dam and in some cases the water permeates in between the shingle layers, moistening the roof deck and potentially the walls and ceilings listed below.
