I live in southwest Ohio. The "contemporary" house with cathedral ceilings has a 1.5/12 pitch. The house has had a shingle roof since it was build in 1955. Now I am told that reroofing with shingles is counterindicated because of the low slope. Instead, I am advised to go to EPDM over ISO board. (How did the roof survive for 60 years with shingles, I wonder?). Is this correct? I am afraid that EPDM when viewed from the street would be unattractive. Thanks.
The minimum required pitch for asphalt shingles is 3:12. That is also the case with metal shingles. A metal option for you would be a mechanically seamed standing seam roof. It would likely fit the architectural style of your home as well. I am curious if your current shingles are asphalt or asbestos.
Honestly...the shingles were better 20 years ago and in this case, they are probably so glued to each other that they formed some sort of monolithic mass.
I'm getting ready to build a small 600 sqft house. Roof is a shed roof with a 1.5/12 pitch. We're having issues finding a roofing installer that is comfortable installing metal standing seam at less than a 3/12 pitch. Does this sound correct? Any ideas for a better solution? We've been recommended going with a mechanical locking system, but the cost is almost double.
As a general rule, for that pitch, manufacturers will suggest a mechanically seamed standing seam. Is there any way you can increase the roof's pitch? What area of the country are you located in as far as climate? What will the rafter length of the roof be?
