EPDM or Torch Down??

The B.a is not as u suggest, and bye degredation, obviously I meant to the degree where it is on the path towards failure is at year 45, I am not sure the type of epdm u utilize, you say carlisle, must be a different form, germaine to NZ, the epdm we utilize does not exhibit the detriments u suggest (i.e- "leaching")>>>

also, the ability to increase the buildings insulation value is significantly increases as well, adding the extra value dimension of saving energy and it's associated costs.>>>

adhesive smell? How does that cause a problem? Unless there are air intake rtu's or vents, it doesn't and it is temporary during install anyway.

Vaa, by substrate "fixings" do mean fasteners? If properly screwed down with the correct length and threaded screws that will not be a problem. As alluded to there wd be at the most one seam, and, again, if done right it will last, worse case scenario, for only one lap just over strip it if there is a worry, for redundancy. Field material degredation does not START until approx yr 45 for epdm. The life still continues many yrs post. So, if installed correctly, the systems life can be extended very easily by simply addressing the flashings if needed. This abilitly to extend the sytems life adds for to it's value. Tearing of corners is most likely to happen prematurely if they were installed incorrect.

AN Epdm roof has significantly less laps, for the size u speak of you can easily have at the most 1 lap, or if u use 30x no laps at all.

The job wd take approx 1/2 with s guys (pending on flashings)

More options for installing underlying insulation.

Honestly, tho i don't do it, Modified seems like a superior product, generically speaking. Like Mike sez, much thicker and seemingly less likely to be damaged. Any more durable, as in length of service? I don't know For me, I like rubber,'cuase it is an easier install for us, and there fore allows me more flexibility. About all I tell the customers as a negative when comparing the 2 is the 'coons like to chew on the rubber.>>>

I would have to say EPDM, without a doubt.>>>
