Many times, when homeowners are experiencing inadequate insulation and ventilation they wrongly assume their home’s doors and windows are to blame because they are feeling drafts.  Quality insulation contractors look at a home to understand the building’s envelope.  That’s because if the home’s attic is an issue and it’s leaking warm air, the home’s interior warm air is rising.  The more air that leaves through a home’s attic, the more the home will try and equalize the pressure through its windows and doors, especially if they are already leaking air.

One of the architectural styles that’s prone to ice dam damage is story and a half homes.  In story and half homes, the upper level has angled ceilings with knee walls.  These features make it difficult to properly insulate and ventilate because heat loss is common. To fully correct the situation, it’s best to remove all of the current insulation and add spray foam to the top of the roof deck and install a metal roof.  This approach discourages ice dam formation because a thermal break is created, causing snow to exit the roof before it has a chance to melt.  Heat cables should be used on a last resort basis because they are not a permanent ice dam solution.

Watch Spray Foam Insulation Being Installed By The Experts of Lindus Construction: 

An ice dam normally occurs when heat loss occurs in the interior of a home and is able to make its way up to the roof deck and causing the snow to melt until it gets to a point on the roof deck where the heat is no longer present.  When that happens, the water refreezes.  Over time, it refreezes enough that the water becomes trapped and unable to exit the roof.  The longer the water can sit, the greater the opportunity for a roof leak to occur.  This can cause the need for insulation to be replaced and can create an environment for attic mold to form.

A critical component of most insulation projects should be attic air sealing.  In this process, spray foam insulation is installed in the attic on the rim, top plate, and perforations.  The attic access is also sealed off to prevent air leakage.  Out of all of the improvements you can make to your home, attic air sealing offers a great return on investment in terms of energy savings.

For homeowners with a metal roof, it’s important to select a gutter system that is sturdy enough to handle heavy snow and ice falling off the roof.  Therefore, many homeowners select LeafGuard® Brand Gutters over open style gutters.  LeafGuard® Brand Gutters are one-piece, seamless, and guaranteed never to clog or we clean them free of charge.  Not only can open style gutters be ripped off a home from ice and snow, but the soffits can as well.  Even more frustrating is that not all insurance companies will cover this type of damage.

"In September 2019 had our Plymouth home re roofed with GAF Glenwoods. Major project with new deck boards, removal of insulation and spray foam. Plus new LeafGuard® Gutters.  Not cheap but done quickly and more importantly correctly.  Carl, supervisor was great. Now we have great warranty (lifetime) insurance discount, and an impressive looking roof."
