This is a good question. But could one not ask the same about copper valleys/gutter linings/ etc.? I understand copper needs to be replaced after 40-50 years. Or is IWS even less durable than that (even when not exposed to UV rays)?

Ice and water I think help in sealing the rake and eaves. This gives us a better sub- roof. When your roof is open for a about 5 weeks I think a little extra protection is best. I don't think it should be use as your first primary flashing like some books tell you (Slate Roofs VSS CO INC). But living in the north part of Vermont it help with iceing. Not to forget how many home owers , builder and architects ask for it!!

I have to ask the Slate Affair people out of curiousity why they use Ice and Water Shield on a slate roof when there is no chance that its longevity will approach that of a properly installed slate roof. If it's an integral part of a waterproof installation, then you are creating a roof that will inherently leak with age.

Here is what we did with the roof. Vermont 12 x 24 Grey/Black from Taren Bros. with 4ft 16 oz copper snow-belt. We used the five foot Roof Gaurd and 3 feet of Ice and Water sheild at the eaves and rake as the under layment.

Are you reslating it or roofing with other materials?
Doesn't look like Monson and probably too early for that.
brownville quarries were earlier.

I was think more along the lines of the slate. The roof is old like you said Walter from the 1850 or earlier. Is it Monson, PA, or Guiford slate. I want to think it is Monson if the house is that old. There is a green tint to them to. Don't you love it when you tear off these roof, how you turn black form all the dust.

There are still quite a few roofs in Maine that were built in the 1820's and 30's with a wooden shingle roof original to the building. When slate became available in the 1850's or so some of these roofs were slated without removing the wooden roof and still remain today.
They're a pain to repair- just rebuilt a chimney on one and reflashed it along with other slate repairs.

Looks like slate installed over wood shakes.
