Research has shown that the best way to ventilate an attic is with a system that provides continuous airflow along the entire underside of the roof sheathing. Achieving this desired airflow requires a balanced system of intake ventilation low at the roof’s edge or in the soffit/eaves and exhaust ventilation at the ridge. Double AA Metal Roofing offers a wide array of venting options for your home or structure. Our Roofing Specialists will assess your current ventilation setup and make recommendations to enhance or replace your system. Double AA Metal Roofing recommends 1 square foot of ventilation for every 150 square feet of attic floor space with half the ventilation represented by intake vents and half by exhaust vents such as ridge vents.
Roofing Ventilation Systems help with both the performance and appearance of your home. Years of research have proven that ridge vents combined with sufficient intake vents is usually the most efficient and effective roofing ventilation system you can install. This balanced system of intake and exhaust through the attic provides greater airflow than any other non-powered vent systems-and it’s the most attractive system visually. In most cases, they blend in nicely with the roof line for great curb appeal.

In addition to helping with your roofing needs, our Metal Roofing Specialists will also help to guide you in your insulation needs. As roofers, we know the importance of reducing condensation in your attic. Proper insulation will not only lower heating and cooling costs, but by reducing condensation, the chance of mold and mildew buildup will also decrease.
Double AA Metal Roofing’s systems automatically reduce the heating and cooling costs in your home as they reflect sun in the summer and insulate from the cold in the winter. To increase this benefit, adding the proper insulation in your attic will make your home cooler in the summer and warmer in the winter. As heat rises in the winter into your attic, it is important to keep the heat inside to avoid paying more for comfort. As the heat attempts to penetrate your home in the summer, attic insulation will not allow the heat to penetrate into your living space as much.
The attic is often the most cost-effective place to add insulation. Typically, a contractor will blow loose fill
into and over the top of ceiling joists. Batts laid sideways over existing insulation is an alternative choice for the do-it-yourselfer.
The air barrier at the ceiling line must be tight to ensure warm moist air from the house does not get into the cold attic and condense in the winter (this is critical). Check ceiling light fixtures, the tops of interior walls and penetrations such as plumbing stacks for air leakage. The picture to the right gives an idea of where air can leak into the attic.
It is also critical to ensure that your soffit venting is not blocked by the insulation that you add. Baffles or Moore Vents may have to be installed to ensure proper air flow.
