We just had our roof redone in May for about $7800.00. That included removal of 2 layers of composite roofing, new asphalt tiles (30 year guarantee), & additional materials. You definitely need to get at least 3 or 4 bids before choosing anyone! I'd also look for someone who is local, & won't charge any money until the job is finished. Lots of people who are scammers want money upfront, & then vanish before the work is done! Ours was started on a Wednesday, & finished up by that Saturday.
Oh yeah, & because different materials vary in price, the cost can fluctuate a lot! The cheapest material is asphalt shingles. The technology for them has changed a lot & some of them look really nice! I don't recommend wood shingles, & in fact, they're banned in some areas due to high flammability. Tile or concrete roofs are really nice, but also very expensive.
Good luck!
