Hello. I’m a first time post. I live in Phoenix Arizona. I have a 2400 square foot home with a 16 year old wood shake roof.Ranch style pitched roof. It is trashed and needs to be torn off and replaced. I do not want to replace it with wood shake.I had a bid to tear it off and replace it with a dimensional asphalt shingle. They say it will need “52 squares”. total price about $10,500. They tell me if I tear it off myself, I can save about $3000.Good idea or bad? Now to throw a wrench into this unaffordable but necessary repair, I have a roofer, client " friend" who would like to do some trade “barter”. If I tear the roof off and haul it away and I supply all the material (he suggest Home Depot for teh matterial), then he and his crew will install the new roof. In turn I will provide him with $3500 worth of my services.(I do landscaping and yard maintenance). Any thoughts on this arrangement?
