Flat Roof Question

Any ideas for a good DIY way to do an almost flat roof, at or about a 1or2-12 pitch? Thanks.

I recognize the usage "do". He wants to have sex with it.

Sorry, cover one. The previous owner did 3 tab on the front porch and did a poor job of laying down rollout on the back porch.

If it was really flat, and I was a really good carpenter (which I'm not), I'd rip it off and redesign it to have some pitch. But, that's based on my opinion that you have to be insane to have a flat roof by choice. One of my neighbors did that, though. He ripped his porch roof down to the beams, and had a carpenter install a pitched roof. Wasn't that expensive, although the neighbor did the tar paper & shingles himself.
As far as your slightly pitched roof, I'm not understanding why you wouldn't install the usual paper + shingles just as with a roof that had more of a pitch. Just do it right.

Several thousand dollars to go crazy with this to rerafter a new pitch on front and back, decking, and fully reshingle the whole house. This is not an option.

Why would you need to reshingle the whole house? Do both porch roofs meet the roof from the main house? Or, are you referring to the shingles on the sides of the house?

I would recommend an EPDM, aka rubber, roof if it is available in your area. It is really not that hard for a do-it-yourselfer and a few helpers. Check out http://www.watertighttech.com/products/roofing/installation/manual/index.shtm . Rubber roofs are bomb proof and will last for many years. Menards in the Midwest sells rubber roofing supplies. Otherwise, try a real lumberyard of a supplier of commercial roofing supplies.

The only reasonable way to increase the pitch is to bring the eaves to the peak. The porches run the whole width of the house. Below is a side view of the house, flat too flat and peak too pitched. The pitched roof over the main part of the house is a low pitch between a 3 and 4-12 pitch. There is no room to simply increase the pitch or change direction of the roof. To change the direction would mean a double pitch roof.

As someone fighting an almost flat roof, watch that you have enough overhang to get the water past the eave, use flashing of the six inch variety to avoid wind blowing water back, use lots of caulk or tar or whatever you're using, and just make it triple what you would on any other roof. Then after it rains, go back and fix the leaks one at a time each time it rains. I'll NEVER EVER do another slightly pitched roof. Royal PITAs even if done right.

.If I were doing it I would strip the old roof,replace any rotted boards and sweep it clean. Then cover the whole roof with Grace Ice&Water Shield and shingle to match house....Good luck with your project....

This was my thought, but was not sure about it. Still not sure about it. I may just have a pro do it, but figured it was best to ask for other ideas.

Somewhat similar circumstances, we first had a contractor redo the flat roof using a membrane to cover the entire roof. Although this kept the room below dry, we had to resurface/reseal it each year and knew that eventually it would spring a leak somewhere. Also the flat roof was inadequately insulated so the ceiling below was warm to the touch during summer time.
So when we got the time and funds we had a contractor do a "roof-over", which we learned about from this forum. The roofing contractor added wedge-shaped blocks of insulation to create a modest pitch and also add insulating value. Since that was done the run-off has been much more controllable and I don't obsess over getting a leak in the roof. Also, I got a tax credit for adding insulation, which may help pay for part of the cost of the work.
This work takes a professional. I would not want to do it myself, for lots of reasons -- one being the warranty that a professional roofer puts on his work. Regards --
