As a retired General Contractor, I ran into these 2 conundrums more than a few time. I would show the client the same calcs you spoke of
and in all but 1 job...the clients came back after the job and said, "you were right, thank you for you honesty..."....Well done At Your Service!!!

[ratfinkrider]

Normally I don't see roof venting on both slopes of the roof, usually they are only installed on the back side of the roof so that it has a nice clean look from the street side.

[raphaelteixeira]

the best video from youtube when it comes to clear explanation. i do hope you make a lot more videos like this

[jbranche]

Thank You, in 5 minutes you gave us a general understanding of ventilation, specifics X vent of X size per 150 sq ft. Additionally answering why and what happens if you have ventilation that is designed wrong. That an Intake may become an Exhaust and circulation and movement of hot air may be restricted. Excellent job with this video.

[jeffstieren]

That is providing you have proper intake at the soffits. You cannot have proper exhaust without proper intake.

I got rid of my whirlybirds and installed a ridge vent. Huge improvement.

[tonybochiano]

More holes in the roof the more possibilities of leaks

[MundiTaurus]

@At Your Service Roofing ... Your video is completely accurate. Of course, too many just cannot seem to wrap their head around facts. EDIT That's why they _need_ people like you! :-)

[GeneralElectricCNC]

Thanks for the info on Corning's web site! I had my roof done two years ago with their biggest flowing ridge vent sections. I need to address the intake square footage now.

[johnoa]

I live in a snow climate, those low profile /low rise vents are soon fully covered with snow as winter starts... After that, no airflow.

The house next door was built in the 1960s and had continuous soffit vents in a screened gap in the plywood. A later reno covered the plywood with aluminum sheeting, but NOT the vented type, so they covered the old vent totally. The most expensive and well known roofer in town installed a new roof a couple of years ago, put roof exhaust venting up top, but did not recreate soffit inlets. I told my neighbor that would cause problems and told her about the bad reno. She called back the roofer who said soffit vents are not needed! So she was angry with ME for humiliating her by having her ask dumb questions of the roofer. Still no soffit vents today!

[davidszakacs]

My first home was a 100 year old two story. I had a new roof installed in the early 80s and the roofer installed only a couple of boxes…no ridge or soffit vents. I decided to add three gable vents a few years later and when A/C was installed in the mid-90s, a power roof exhaust fan was included. The shingles that were put on in the 80s are still on and NOT leaking! That’s around 30+ years. Oh, and those are 25-year shingles.

I warned a neighbor about their north-south ridge with predominant west winds before their new roof installation. He surely didn't really follow, and surely wrote it off as remote-chance nonsense, and that the roofers will make an adequate decision. Well guess what -- their ceilings got soaked. So my experience and suspicion was right after all.
BTW, I believe the ceilings are fixed, and the roof is still the same -- it's likely to happen again.

BBTW: I would really warn against roof ridges perpendicular to predominate winds with a house situated on the up-hill side -- winds get even stronger there.

[jamesdunn]

Continuous ridge vents can become clogged over time in windy, dusty regions and loose their effectiveness. Another method might be using an attic fan exhausted to the outside. There are solar powered models available .

My question/comment is in reference to current building science and the latest building codes. I have recently built my own off grid house and am currently building an off grid cottage. Both structures have 6 and 4 inches respectively of XPS rigid insulation on the roof deck under 2x4 battens and the steel roofing. The area under the roof is conditioned space. My house has been through 2 full winters in the mountains of CO climate zone 7 I believe. I have 0 roof vents and have experienced no condensation or moisture problems that I'm aware of. How do you or anyone else with roofing experience feel about my choices? Oh, it's a 1300sqft 2 story house off grid with solar power for electric heat and a propane backup rinnai wall heater. I'm also using a whole house HRV.

The more modern approach is to use spray foam insulation which requires a sealed attic space. That was the method used in my house constructed in 2001. The spray foam was applied when the weather it was warm and the different in temp inside the house before and after the foam was applied was amazing even in the sealed attic space with a metal roof.

The spray foam also adds structural stability and soundproofing. The house is a mile inland in NC along the ICW where we’ve gotten winds of 70mph+. I my other houses with aluminum or vinyl siding and fiberglass bat insulation it would be howling and rattling but in ours with cement Hardie Board exterior and spray foam it is sealed like drum, so much so that the HVAC need and outside inlet for fresh air, and very quiet.

[paulrobinson]

I like Whirly bird vents for my roofs.

[bluer]

My roofer (gaf certified)pointed out whoever did my soffit only put vented panels on one side of the house. So now i need to remove gutters, facia and install vented soffit on 3 sides (hip roof)so i get proper venting also recommended getting rid of the power vent and used those box vents but had to add a few. Old roof had a power vent and about 4 box vents.

[heroknaderi]

I agree. Oh and what about the turbine vents I’m curious do you prefer them too
