Questions & Answers

Hi, I have a house with a length of 120 ft roof how many of this vent I need thank you

Asked by: Bruce
I am a designer and the pro answer is not quite complete. Under 2013 Title 24 Code the formula is as follows: Total attic( or roof area ) in square feet, divided by 150. This gives you total square feet of attic ventilation required. Multiply that number by 144 ( square inches in a square foot ). Vents are specified by net free air flow in square inches. Take your total square inches required and divide that by 2. ( Total number of vents should be balanced between intake and exhaust ) There are many vent shapes, styles, and sizes. I.E. ridge vent, half rounds, gable vent. If you cant balance intake verses exhaust exactly, always provide slightly more intake vents to meet the total net square inch ventilation requirements.

do these dormers need to painted inside and outside before installation?

Asked by: lesvelos
They do not "NEED" to be painted, but they will look nicer if they blend with the roof. And they'd only need to be painted on the exterior, no reason to paint on the inside.

can I use this type of vent on a low sloped roof: 1/2:12 slope

can I use this type of vent on a low sloped roof: 1/2:12 slope
Asked by: javier
Thank you for your inquiry. Not recommended for a 0.5/12 pitch as heavy rains could present a leak issue. However, any pitch between 2/12 and 12/12 should work. Traditional best performance between 3/12 & 6/12 pitch.

Rated 3 out of 5 by from I returned these and chose a different vent. No... I returned these and chose a different vent. No problem with the product - they were visually far too large for the shed I was going to use them in.
