Do the tear off yourself. It is a good experience and makes a person appreciate the effort roofers make, to make a living, and buy their Guzzis. The money saved can go towards a new small block or something. Best of luck with your decision.
The respect I have for roofers is their ability to do the work year round. But yes whether you strip the old ones first or add a layer, it's way cheaper to do it yourself.
I don't know......roofing is tough work. I've done small out buildings but don't think I would ever tackle a 3,000 sq ft roof. A good team of roofers can strip and replace a roof in a two or three days.....weather permitting, haul off the debris and I can drink a couple of beers while watching. Game, set and match.
I live in the northeast and a couple of years ago we had roofs caving in all over the place. Two or three layers of roofing is quite heavy and then add a foot or so of heavy snow ?? Just say'n.
