My wife & I are looking at buying a house in the Seattle area which has an older shake shingle roof. I am trying to get a rough idea of what it would cost to replace this roof. I know it is impossible to come up with an exact figure without a professional actually coming out & doing an estimate, but at this point I'm just trying to get a ball park figure. The house has a 1st floor of ~ 1900 sq'. It has an attached garage of ~ 600 sq'. Both are covered with a straightforward, run of the mill sloped roof ending in gables. The house was built on the mid 70's, the owner has disclosed that the roof has been "repaired", I'm guessing if the majority is 30+ years old, a replacement is in order. Whether we have them do this as a sale condition or use it as a bargaining point to reduce the cost, it would benefit us to have some idea of replacement costs. Also, while you see a lot of these roofs around here in certain areas, the notion of bare wood being the best possible roofing material in such a rainy climate seems a bit illogical to me. I've seen several that look awfully mossy/mildewed/waterlogged/rotten Are there any newer alternatives worth considering, metal, perhaps?
