Inadequate ventilation, caused by blocked soffits or other factors can cause damaging heat build-up in the summer that can cause your roof to age prematurely. In the winter a poorly-ventilated attic can experience moisture buildup and condensation that could lead to mold, mildew, wood rot and ice dams. These problems are exacerbated if a roof is poorly-insulated or if plumbing vents, bathroom fans, dryers, and kitchen hoods are vented into the attic and not directly outside through a properly insulated pipe and roofing vent. Heat loss into the attic from recessed lights and other air leaks from your living space are also a major contributing factor to attic problems.
In fact, many of these problems are so detrimental to the health of a roof, that many shingle manufacturers require proper attic ventilation to validate the full terms of their shingle warranties.
We have also seen our fair share of critters taking up residence in people’s attics. Bird and bat droppings are toxic to humans and must be professionally remediated. If caught early on, these issues are easily dealt with.
Did you know that roofers often include a certain amount of “new” plywood as part of their quote to replace any damaged plywood sheets they may find when re-shingling the roof? If you know about a few sheets that look bad from the inside before they do the job, you will benefit from their replacement at no extra charge.
Should any these problems be uncovered following an attic inspection, they can easily be addressed during the roof installation, saving you time, money and aggravation. If you’re going to get the job done, it pays to protect your investment.
