Question

WE LIVE IN THE DESERT OF SO. CALIFORNIA. WE HAVE A 21 YEAR OLD ROCK ROOF THAT NEEDS TO BE REPLACED. MY HUSBAND IS IN THE PROCESS NOW. HE IS DOING HALF OF ROOF AND OUR 10 BY 30 PATIO ROOF. IT IS READY FOR THE "FAKE SHAKE" SHINGLES, EXCEPT FOR THE PATIO ROOF. HERE ARE HIS QUESTIONS.
1. THE PATIO ROOF HAS A 1 IN 12 PITCH, SO WE KNOW WE CAN NOT USE THE SHINGLES, WE WILL INSTALL THE ROLL TYPE,CAN YOU UNROLL AND INSTALL THE WHOLE ROLL AT ONE TIME OR DOES IT NEED TO BE CUT IN SECTIONS AND OVERLAPPED,AND WHAT SIZE SECTIONS SHOULD IT BE CUT TO?
2. IS THERE A WAY TO INSTALL THIS ROLL WITHOUT EXPOSED NAILS?
3. DO YOU NEED A STARTER ROLL FOR THE ROLLED ASPHALT, IS SO, SHOULD IT BE TURNED UPSIDE DOWN?
4. WHERE THE 1 IN 12 PITCH MEETS THE HOUSE ROOF WHICH IS 4 IN 12, SHOULD YOU OVERLAP ROLL ONTO 4 IN 12 PITCH?
5. WE WILL USE THE "FAKE SHAKE" SHINGLES ON THE HOUSE ROOF, HOW FAR SHOULD THEY OVERLAP THE ROLL ASPHALT ON PATIO ROOF?
6. ON THE FLASHING, DO YOU BEND IT AROUND CORNERS OR DO YOU CUT IT AND START A NEW ONE?
THANKS FOR ANY HELP YOU CAN GIVE US!

If you want to do something that will last you can install modified bitumen rolls or cap sheets. This is a material that looks exactly like 90 pound roll roofing but is modified to allow for expansion and contraction and is better suited for less steep areas. Some is made to be torched down and some can be put down with an adhesive. I assume you have removed the old roof down to the wood deck. Next step is to nail down a 33 pound coated base sheet. This is not the same as 30 pound underlayment felt, it is much heavier. Apply at least a six inch strip of roofing cement or mastic at the perimeters to set the first sheet in. Don't be stingy with the nails, the roof will be attached to this base sheet and you don't want it blowing off. Run the base sheet at least a foot up the area to be shingled. The higher the better. Up north we would run it up at least 3 feet for snow build up. The cap sheet rolls should be opened and allowed to "relax" in the sun for at least 10-15 minutes. This will prevent wrinkles after they have been installed. After the base sheet is installed apply the adhesive the width of the roll at the edge. Install the first roll. Nails can then be applied about 8" O.C. at the top where the next roll will cover it. Continue on up the roof in the same way. When this roof is complete, install the underlayment for the shingled area and let it cover the top of the last cap sheet roll. Start shingles at a point that looks good to the eye. Probably no more than a foot or so. This material is only going to be found at a good roofing supplier and it's not cheap. But if you'd rather not do it again in 5-6 years spend the money.
