any advice. the home is 1,400 sq ft, how would i price it around what is the going rate per sq ft? i read some on the asphalt roofing manufacturer association what they recommend. should i just downstream 50/50 mix of SH or straight 10% SH on the shingle roof and let it dwell and rinse, apply if needed etc. this is my first time.
