attic insulation and ventilation

Venltilation Matters

What is attic ventilation? Balanced intake and exhaust “Ventilate” comes from the Latin word for “to fan.” Simply put, it’s the action of moving air. Out with the hot. In with the cool. And that’s exactly how ventilation works. It provides conditions that allow air to flow. Every time stale, the overheated air in your home or attic is vented out and fresh air is pulled in to replace it, you have what is known as an “air exchange.” But ventilation is much more than a simple breeze blowing through your house. It’s a the process that provides a steady, high volume of air movement. Think about it as a system of components, all sized and positioned to provide constant intake and exhaust of air. Roofing Above All calculates the balanced ventilation your home requires, enabling you to effectively “wash” the entire attic by pulling air from the intake vents low on the roof’s edge or in the soffit to the vents at the ridge in the high areas. More is better, right? A sure sign of poor ventilation is an unbearably hot attic in the summer. Another thing to check is evidence of moisture, such as mold, mildew, rustedRead More…

Ice Damming

Winter and roofs Ice dams are most common in northern climates that are subject to heavy snow buildups on roofs. Ice dams occur when this heavy snow buildup melts during the day and then refreezes when temperatures fall overnight. After several days of the thaw-freeze cycle, it’s common for the ice to work up under the shingles until it reached an area of the roof warmed by your home. This is when your home becomes vulnerable because that ice begins to melt from your home’s warmth and causes a leak. This leak can potentially damage your ceiling, walls and the contents of your home. The problem worsens because insulation loses its R-Value when it gets wet. In cases where the ice dam goes unnoticed for an extended period of time, there can be significant damage to the building and its contents.
