One clown "you don't need to buy them, I'll build them on-site" (really? without a flat 70' pad? one at a time? by the way, who's paying an 80' crane to standby 2 weeks while you are fabbing 50 trusses?). Another wanted to overlay the very faulty flat roof with scabbed rafters! (hello? we get snow here WHAT'S that roof load going to be? He didn't get the job either, didn't go inside to see 15 termite eaten posts.)
I'm in no way an expert at construction. But if logic and engineering don't add up, something's amiss. I talked to most every roofer in town; all had schemes of membranes, spray coatings, re-shingling, etc. Only a real construction contractor had an appropriate combination. I didn't tell a single one what I wanted or thought should be done.
That's their job.
