Replacement For Corrugated Roof Panels



I have a patio with corrugated fiberglass roofing. The panels are old, look horrible, are loose so they rattle when it's windy and no surprise, they leak. Some of the rafters that support the panels aren't in great shape so I'd like to remove the panels, replace any rafters that need it and paint all of them.
The problem I need help with is finding a decent substitute for the fiberglass. The roof is almost flat so tying in with the 3-tab roofing of the house isn't an option. The roof is also very low. It's just 86 inches from floor to the bottom of the raters at the highest point. It slopes to 82.5 inches across the 13 foot width of the patio
I live in the rainy Seattle area so an open roof / pergola doesn't seem practical.
The house is 80 years old and used to be a barn so those add-on sun rooms wouldn't match the style of the house.
Any suggestions would be appreciated.

Exactly how is it tied to the house, since you don't have the option of tying to the shingles? Are all the panels corrugated fiberglas? You may want to post a couple of pictures so we can see what you see. http://forum.doityourself.com/electr...your-post.html

Yes, the entire covered patio area has corrugated panels for the roof. (part of the patio is uncovered). The wood rafters for the patio are attached to the facia on house and the corrugated panels sit on that wood and are tucked under the edge of the houses roof. I'll get some photos taken today and post them to show it clearly. Thanks for the reply.

In the meantime, do you want the translucence in the roofing, or solid panels?

Here in cloudy Seattle some translucent would be nice but my main priority is something that looks nice. It's a real eyesore now. if the camera battery is charged I should have some photos soon

A photo of the patio and a bit of the roof of the house http://www.torrtech.com/House-Patio.jpg
The patio is 13 ft across, the covered area is about 20 long with 10 ft uncovered
Here's a closeup of how it's attached at the roof.http://www.torrtech.com/AttachCloseUp.jpg
You can see how the corrugated panel is tucked under the roof
If there are any other shots that would be helpful just let me know.

That's a long span for 2x4 lumber. I like the wringer washer, too. I'll only address the covering and let you check span tables for the 2x lumber required for that span. You can purchase galvanized panels of the same design as your fiberglas. Having only one or three of the fiberglas panels across the span, and the galv panels filling the majority of the roof, you may have a better looking roof and one that is not as susceptible to damage from falling limbs, etc.

Does the photo look like the panels are sitting on 2x4s? Those are actually 2x6 but I'll definitely check about code.
Thanks for the tip about the galvanized panels. I'll check them out. Sounds like a reasonable solution.
Glad you like the wringer washer What do you do with something like that when you inherit it? Fill it with pansies and put it in the yard? I'm sure somebody creative could come up with something fun.. I just need to find them!

You're right on the size of lumber, but it will only span about 10' 6 without midspan support. My dad grew his best tomatoes in an old toilet base. Somehow it was able to retain just enough water for growth and allow the excess to drain off. Interesting how we use old things.

You're in Seattle -- about 50 miles south of me. You want as much natural light coming thru the cover as possible. Tis is not an option for a patio cover. (Too dark!) Fiberglass is somewhat better, but still pretty dark. I use the clear Tuf Stuff panels frome HD. As much light as possible gets thru and they are acrylic -- MUCH stronger than fiberglass.

Thanks Lefty. I'll check them out. I agree about the more light the better in the part of the country.

I'll just add $0.02 in here.
I lived in Seattle and did roofs. (FHS 57)
Difficult to imagine why the builders of the Patio, obviously added afterwards, didnt snuggle the Patio up to the Soffit board and meld the roof into the patio panels.
Move the Patio Mating plank up to the Soffit plank of the house.
Slide your new Fiber glass panels up under the roofings First Undercourse, and go on out from there.
You have a contigous leak proof extension of your roof.
You can go out to the Headache board and raise that up to suit you or leave the angle as it is for better drainage. That will do wonders to keep that dirty stuff from collecting up there.
It's not too late to do that now. You could raise your Patio roof about 6 at the roof and some out at the Head banger at the top of the steps.
I saw this once in Alaska over a guy's patio. He'd somehow cast a large Fiberglass looking bubble and fastened it down on his patio. It looked great. I see them on Roof lights as well. Maybe a Plastics Mfg in Seattle can quote you on that?
In AK I wanted what you have, but couldn't!
So I bought one of the Curved Glass Atrium or Greenhouse thingys. It was used. A lot of work but when it was all done it was a great place to lunch and have coffee in the evening.
The drawback was the constant dripping. That thing condensed about half a gallon per day in constant dripping. It had a vent you could crank open, which helped, but the solving was a Fan set out there that ran all the time.
Boy was that a great place for gardeners and flower pot people.
