I'm slowly remodelling each room and have decided that I need to replace my back-patio cover. It's one of the aluminum covers from the 70's or 80's era. The problem is that it's a flat cover and all of the water runoff is being dumped to one side. (not possible for a gutter system on this cover the way it's designed) I want to replace it with something more up to date, but can't afford to pay a contractor. I want to build it myself, which I'm capable. I just don't know how to build this and handle water runoff. All of the water would need to be directed to the side of the house. Here's a picture: http://oneweb.utc.edu/~psw478/backpatio.jpg If you look at the cover, there is a portion of the cover that was added by the previous owner. I have replaced this with a sloping shingled roof, but I can remove it when I put the REAL cover on, if I choose. The dimensions of the cover are roughly 20 feet in width and the cover comes out from the house 10 feet...I would need to extend this to 12 feet. -Thanks    Filesize:  80.97 KB  Filename:  backpatio.jpg  Viewed:  428 Time(s)

These rafters would extend from that point out to where the posts hold up the metal roof. You could install new posts and a beam to support the rafters. It appears that you may have enough slope to be able to use regular asphalt shingles over 15- or 30-pound felt tar paper. You would need to check to see if you can get a 3-in-12 or 4-in-12 slope for proper drainage. (3 inches of height for every 12 inches of horizontal distance) The new shingles could tuck under the old shingles if done very carefully. (You could also re-roof the entire roof.) Proper flashing would be needed at the intersection fo this new roof and the wall. New rain gutters and downspouts would allow you to channel the runoff to any location of your choosing. You could do a cost comparison of rafters and inverted trusses made of 2X4's. Inverted trusses would need to be designed by a professional structural engineer or other competent design professional. You would have to check your local building codes to see if this is acceptable. This could also require removing the first foot or two of the existing roof to be able to tie the trusses to the wall properly. I recommend that you get advice from a competent builder or other design professional before tackling this project on your own. You do not want the liability of having the new roof collapse from faulty design. It must be designed to handle any wind or snow laods and must be tied to the ground and to the existing building properly and in compliance with any applicable building codes.
