Shingle Roof Replacement in Dundee

Two, properly. They are different systems with different lives and different prices, and a single figure for 'the roof' nearly always means one of them was estimated rather than priced. The transition between them is the detail that decides both.

Architectural on a building you intend to keep: $5.50 to $8.00 per square foot against $4.50 to $6.50, heavier, better in wind and longer-lived. Three-tab is defensible on a small front slope or a building being sold shortly.

At an edge, almost certainly. An attached building has no eaves, so water leaves through an internal outlet or a scupper through the parapet -- and the failures are at the coping on top of the wall, at the upstand where the membrane turns up it, or at the outlet itself. The field is usually the last thing wrong with a roof here.

Rubber means EPDM, at $5 to $9 per square foot: bonded with adhesive and tape, black, and the least expensive single-ply. TPO is $6 to $12, welded at the seams and reflective, which matters on a large roof over occupied space. On a small rear addition EPDM is usually the right answer rather than the cheap one.

Two to five days on a house, four to seven on an apartment building, and one to three weeks on real commercial work. The roofing is rarely the long part: the street arrangement, the route onto the roof and any tenant notice periods are what set the start date in this city.
