Low Slope Roof Ventilation

One of my goals this year is to learn about ventilation for my customers so we can make good recommendations for them.

Low slope roof ventilation.

November 19 2014 9 08pm 1. Look at our fasciavent which has been designed more specifically for metal roofs and provides the intake ventilation for flat to 16 12 pitches. Unfortunately too many builders and roofers do not include any ventilation on a low slope roof as it is easier for them to avoid potential leaks. Hi all in new.

Where the location of wall or roof framing members conflicts with the installation of upper ventilators installation more than 3 feet 914 mm below the ridge or highest point of the space shall be permitted. The top of the roof meets the wall of the house and the 2 sides also meet walls. I m a flat low slope roofer. R806 3 vent and insulation clearance.

The universal design looks great on a shingle roof. Hip and ridge shingles starter shingles low slope products ice and water barrier synthetic underlayment intake ventilation exhaust ventilation titanium and rhinoroof. The universal dormer vent is a low profile off ridge roof vent that is designed for a pitched roof of 3 12 slope or greater. Last year i ran into several flat and low slope roofs with vents on the top of them in different scenarios 2 12 slope barrels and near dead level.

In the case of low slope roofs builders and roofers not only need to solve the ventilation problems but they also have to make sure that there are no leaks caused by the air vents. For this design to work well on a low sloped not dead flat roof an outside air inlet is provided by a soffit or roof overhang built at the low end of the roof and a roof cavity air vent outlet is provided along the high or up slope end of the roof using a built up half ridge vent. The universal dormer vent can be used as an air intake vent or as an air exhaust vent depending on where you install it on the roof. Smartvent low slope application smartvent can be modified to provide intake ventilation for new roofs or re roofs through the fascia board for low slope roof with less than a 4 12 pitch.

I m trying to vent a 1 12 roof that has not been vented.
