installing fiberglass patio question
i am looking to build an enclosed porch. I was looking for some hints on how to tie the roof into my existing one. I would like to enclose the entire patio area. Im not sure what type of roof to build, and how to deal with the existing roof line on the right.
Any suggestions would be great.
Need a better pic of the peak over the doors leading to the patio
Where are you located ?
Here you go. Let me know if you need more.
I am located in chattanooga, tn
If I'm reading the numbers right you have a 18' 8" run to the far edge of the patio
I'm not sure if there is a lot of snow in TN ?
I'd be inclined to raise the peak & run the roof higher then the roof on the right
Keeping the same roof slope as the existing roof
This would make for a very long roof & high
Enough room on the 2nd floor for storage or a cathedral ceiling in the new area
You say fiberglass patio ? Is this a kit you are buying ?
What will be fiberglass ?
A crude drawing:
Existing roof in black....new roof in red
This would mean adding onto the front roof, that might be a problem if you do not have the same shingles
Thanks for the reply scuba_dave,
here is a link thats close to what im looking for in a roof:
The difference would be i want it screened in.
I want to be able to keep as much light as possible going into the patio doors which leads to the kitchen.
The picture i attached is an idea of what i am looking for. I would change the windows in that picture to screens.
OK, since it won't be screened in it won't be heated
So not too worried about rain etc getting in
You could split the distance & put a peak at the middle
The roof draining towards the house would empty into the existing gutter
That product requires a min 1" per foot
So at a bare min the middle need to be approx 9" higher then either end
The higher the better for shedding rain & snow
Seems you usually only get light snow there....2" ?
But you may get storms every now & then up to or over 10" in the past ?
A low slope may not hold up that well to snow with the fiberglass
But seems they are rated for a snow load
2 different roof designs show
For a screen room I'd be inclined to go with the longer slope roof myself
The roof with the peak in the middle would allow a ceiling fan to be installed out of the weather
i like the second design..what do you think about the attached design. It would tie into the existing roof. What are the pro/cons of each way?
You could do the yellow roof
But you then need to tie into the existing roof
And you are putting weight on the existing rafters & roof
The existing rafters may not be sized for the load
Properly supported, existing roof/rafters re-inforced as needed & tied in correctly it would work
Lower slope....would require stronger support for the panels
And it is probably be too far of a span, but a beam perindicular to the roof angle would solve that
thanks for the response...i have some food for thought now...
