I have a low-slope roof and I’m hoping to replace the old tar and gravel with the Resisto product made by Soprema, but I’ve had conflicting views on its durability and ease of application. I’ll have a 20-year building contractor (not a roofing specialist) doing the work. The roof is 1.5/12 in a high rain area (Vancouver Island). Does anyone have any experience with this or a similar product in a rainy region? Any suggestions or recommendations for application?

Is this the 3 layer stuff where you have to torch down the top layer?
No, it's a cold adhesive product (http://www.resisto.ca)
I do not know enough to answer your question but I have one of my own, why not a metal roof or EPDM membrane roof?
The slope is too low for metal, which was my first choice. Ditto for EPDM, I'm afraid.
If the slope is too low for EPDM, it is definitely too low for a peel and stick.I've used the Polyglaass peel/stick and been happy with it, but it is no where near as good a product as EPDM

No such thing as too low slope for EPDM. We do zero-slope (flat) EPDM roofs with 50 years warranty. It's a pool liner material, for crying outloud. Where do you get your info?

that's not really possible.
How can a peel and stick be applied to a lower slope then EPDM.
The rubber is a single sealed membrane with no where for water to penetrate, with peel and stick there is always going to be a lap which could over time come loose and allow water in.
I have great success with a product called Seal-O-Flex. Here's a recent poject -

90 year old tin roof and Yankee gutters was in sad shape -

Demo-ed down to 1x sheathing, screwed down 1/2" CDX. the "doghouse" will have a door to give access to the roof from the attic - it's too darn high from a ladder. I did all this with a lift. You can see that the Seal-O-Flex membrane will go up and around the doghouse, and will form the shallow valley with the main roof; shingles will be top-pinned and glued around it.

Recoat white, one coat every 5-8 years - much better!

Great pics & finished product looks good. Thanks for the idea - I'll explore it.
Last summer I laid down a low sloped 1:12 roof with a product from Harvey Ind.

I believe it was the Elastoflex line.
Fresh plywood then their first layer is like a smooth heavy duty Ice & water membrane. Second layer was the granular finished product. Both were peel&stick and had a the second layer had a 3" overlap strip that was also peel&stick. After it was installed we had 10 days of rain and I did not notice any leaks.
It installed pretty easy but as with any peel & stick...the hotter the messier. I'd recomend it again. It is available in a bunch of colors if you special order.
Good luck.
