Attic Air Flows

Grab a flashlight and inspect your attic during the winter.

Attic air flows.

The ice traps water behind it allowing the water to seep back under the shingles and leak through the roof. In the summer natural air flow in a well vented attic moves super heated air out of the attic protecting roof shingles and removing moisture. I have a shop in my attic for some of my hobbies and it get s very hot in the summer. Look for water stains on the roof sheathing or damp or moldy spots on attic joists and existing insulation as a clue to where leaks might be.

Air flows in through the soffit vents and out through the roof vents. Proper attic ventilation consists of a balance between air intake at your eaves soffits or fascias and air exhaust at or near your roof ridge. We insulate moisture proof and throw up every barrier to heat and cold. These ice dams form when warm attic air melts the snow on the roof and the water refreezes along the colder edge of the roof.

Instead fresh air still flows in through the soffit vents and travels along the underside of the sheathing until it reaches a ridge vent or can be vented with another type of exhaust vent. I have large attic with ridge vents and screened vents at either end of the attic to maintain air flow. Extremely satisfied with the professionalism speed and craftsmanship that robert and his team at attic air provided. Misconceptions about the air flow in your attic can lead to thousands of dollars in damage and repair costs.

Can i put a small swamp cooler or ventless a c unit up there to cool it only to use while i am in my shop maybe an hour or two a couple times a week. For the best results place roof ventilation near the roof s peak and soffit vents in the eaves. It creates a breeding ground for mold and mildew and ruins the air trapping pockets that block heat flow. Proper insulation and air sealing also keeps attics cold in winter by blocking the entry of heat and moist air from below.

Increased ventilation will make the entire roof cold and reduce or eliminate ice dams. Fans and vents may be installed on the roof system that will draw the air out of the attic space and exhaust it to the exterior. Box out light fixtures. Water is insulation s enemy.

Whole house fans powered attic fans. Your home is a heated conditioned area that is designed to keep air in. I highly recommend them for your attic and air related jobs. Federal housing authority recommends a minimum of at least 1 square foot of attic ventilation evenly split between intake and exhaust for every 300 square feet of attic floor space.

If you see dampness or frost you need better roof ventilation and some attic vents. Vents come in various styles. Attic air was able to complete the job and clean up all dust and insulation that fell through the attic and vent the fan through the roof in a short amount of time.
