Hello Connie
Good to see you back. You still haven't fixed that old roof yet!
You take 36 x 32 and that gives you 1,152 square feet of area. Then you put it into a roofing calculator website and you get this.
To have 10% buffer would require 13 roof squares.
By United States standard, the roof will need:
35 bundles of composition shingles (each bundle will cover ~33 ft2)
12 rolls of roll roofing (~36 in × 36 ft for each roll)
3 rolls of #15 felt (~36 in × 144 ft for each roll)
6 rolls of #30 felt (~36 in × 72 ft for each roll)
Roofing ceramic tiles do not have a standard size. Consult contractors to determine the amount needed.
So you need 35 bundles, but you could probably get away with 32 if it is a nice rectangle.
I helped you before as Andrew Taylor, I changed my name.
