Hey guys,our specialty it’s to install asphalt shingles. Last week we got a call from a home owner,saying he has a small commercial building 43 squares 2:12 pitch. He said he would like to know the difference between a sheet metal and a thermoset roofing system as far as price cost and he also asked us what kind of metal fasteners are more compatible with all kind of metals?? our answer was stainless steel.
after we explained to him the cost of the thermoset system,he was wondering according to the florida code how many layers of roofing flashing membrane we have to use?? we said two layers. were we right or wrong??? Thanks
any input will be greatly appreciated :?:
