Your attic can reach extreme temperatures well over 150 degrees in during the warm summer months. This can cause significant damages to the lifespan of your roofing system as well as create additional stress on your cooling system. A roofing fan is often used in the attic to help ventilate excess heat in the warm Loudoun County months and help create airflow through the soffit to prevent ice dams from forming in the winter. But do you need a roofing fan for your home? Use this guide to roofing fans and decide for yourself if your home will benefit from the installation of a roofing fan.

It’s no secret that attic areas can be extremely uncomfortable in the summer months. But did you know that your attic temperatures can reach well over 150 degrees, causing severe roofing damages to asphalt shingles? Shingles that have too much heat buildup under the substrate can cause them to buckled and warp under these stressful conditions. Attic heat buildup can also cause your air conditioning system to work harder and use more energy. When humidity rises, moisture build up in the attic spaces can become a huge concern as well. When moisture and heat are allowed to combine together in the attic space, they can become a catalyst for mold and mildew problems. Black mold can form, causing severe allergic reactions, respiratory problems and in some extreme cases, even death. If you suspect that you may have black mold or other attic mold or mildew concerns, call Roofer911 today at (703) 475-2446 or send us an email at Roofer911@gmail.com. We’ll send a team of qualified roofers to give you a 100 percent free, no obligation inspection of your attic space.

When some roofing contractors install attic fans, they simply choose a fan, cut a hole in your roof and plug it in. While this can help to alleviate some of the homes heat buildup, without knowing where the problem spots are in the attic insulation and exterior walls, you may be removing air conditioning or heat from the interior of the home causing the heating/cooling system to run even more, making energy efficiency even worse. That’s why at Roofer911, we offer all of our customers who want an attic fan installed a free infrared thermal scan. Our qualified team of technicians will provide you with thermal images of your homes insulation weak spots. Once we determine the attic insulations weak spots, we can fix your insulation problems and concerns by adding more insulation to the attic and ceilings spaces that need it most. Once complete, your attic fan will work at peak efficiency, ensuring your attic temperatures decrease, humid air is alleviated and your air conditioning and heating systems will have to work less to produce the same effect.

Not all attic fans are the same. Each attic fan ventilates and disperses a distinct amount of hot air from the attic space. This air movement is measured as cubic feet per minute or CFM. Calculating the correct CFM for your attic is simple. Find the square footage of your attic space by multiplying the length time width of your attic area. You’ll need to multiply the attics square footage by .7 to get the minimum amount of CFM for your attic fan. For steep roofs, multiply the square footage by 1.7 and for dark colored roof shingles multiply the square footage by 1.15 to get an accurate minimum CFM for your attic fan.
