Rubber Roof Replacement in Dundee

On a roof you intend to keep, 60-mil. The uplift on a small roof is modest and it buys real puncture resistance and durability. On a small rear addition you expect to rebuild within a decade, 45-mil fully adhered is entirely adequate and we will say so.

With mechanical fastening, yes -- it is screws through the deck. Fully adhered avoids that, which matters over a trading shop or a bedroom. It is worth raising before the system is chosen rather than after the first complaint.

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.
