Flat Roof Replacement in Dundee

More urgent than in a warm climate, and more urgent on an attached building. With internal drainage there is no edge for it to overflow from, so it ponds -- and water in a lap through a freezing week expands, lifts it, then thaws and runs in through the gap.

Often yes, and it is the cheapest genuine improvement available on a roof here. Original outlet capacity was frequently marginal, and on a parapet roof the consequence of a blockage is the whole roof flooding rather than water running off an edge.

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.
