Anyway the issue of venting is now in the project.
If enclosing a porch does roof need vented.
It s also got an almost flat roof with solar panels on top.
I already put down 3 4 osb and a rain ice barrier.
So incredibly hot which i expected.
In my experience i would vent all my roofs with soffit vents and ridge vents using the foam rafter vents between the sheathing and insulation.
On top of the roof i would like to put down a metal roof.
Do i need insulation and or ventilation on top of the rain and ice barrier or can i get away without it.
The roof attaches just above the eves of the house roof and the eves are open.
People have strong and differing opinions on whether roof venting affects shingle life.
Proper roof ventilation is an important aspect of home construction.
He originally told me to use the vent available for a shed roof situation but the manufacturer says not for any thing less than a 3 pitch.
However this porch was enclosed with windows not just screens.
It is a 1 1 2 pitch shed roof.
I can t think of the benefit of venting a screen porch roof.
I ve finished enclosing a 35x12 porch.
Louvered vents provide good air flow for roof areas.
Knee vents that fit along the area where the roof joins the house can also provide good ventilation for porches according to the roofing contractor review website.
I can t find it in the code book which is what he is citing.
If you have an enclosed porch ceiling have vents to clear the roof cavity of moisture.
I ll be soon building my open air porch on my house soon ne ohio.
The joint where the top of the porch roof meets the wall needs to be flashed well and most of the vent details for that look to me like they might leak water under some conditions of rain and wind.
This will not be an enclosed porch however the roof and ceiling joists will create an enclosed structure.
I am not planning on enclosing the porch.
It s got 15 6 tall south facing casements with 2 french doors on one side and a double french on the other end.
Roof vents help make a home more energy efficient and allow humidity and hot air to escape the.
The rafters are fabricated i beams.
I plan on putting aluminum soffit under the i beams.
Do i need to ventilate.
It will be a simple 3 12 pitch roof tying into the house front with ceiling joists with pine 1 4 tg beaded boards for ceiling.
Soffit vents have much less risk of water entry.
If you plan to include a ceiling fan in your porch make sure you take that into consideration when deciding on the height of your ceiling.
Do i need to vent the roof of a screen porch.
If your porch is screened in you can run your ceiling up to the peak and install ridge vent on the top of the roof and you should be fine no need to insullate a screened in porch.
If your porch has developed ceiling stains or problems shedding snow and ice in the winter try providing additional venting for the roof system.
