Has anyone here tried any torched-down modified bitumen on a home roof? We
had it installed on our low slope industrial roof, and I love this stuff!
Especially since I'm in charge of the maintenance.

I live in Massachusetts and have a low pitch (2-3) roof over an
addition to the house. At the valley where the low pitch meets a
standard pitch roof, there has been some roof leak problems when there
is a lot of snow. Last year I had a guy lay down some ice and water
shield, but it turns out that it hasn't worked.

I've had a couple of guys come out and offer some solutions. Here are
their recommendations:

(Contractor 1): Rubberize the roof.
(Contractor 2): Rubberize the roof.
(Contractor 3): Use polyglass product which seal the roof like a
rubber product, but offer a textured (granulated surface) that will at
least sorta match the shingles on the roof.

When I look around, it seems that I've noticed many "low pitch" roofs
that don't have "rubberized" roofs. And I've yet to actually see a low
pitch roof w/ rubber. I'm hesitant on putting a pitch black roof on
top since the roof is visible. So i'm leaning towards the polyglass
product, but was wondering has anyone had any experience w/ polyglass?
How about Low Pitch roofs? Is there another solution that I've missed?

The quotes have been all over from less than 2000 to 4500.

The roof area is about 22' x 12'.

If the leak is where the two pitches meet, reroofing the lower roof may
not help at all, unless the structure and covering of the junction are
addressed/
The roofer is in the same position as asking a car dealer whether you need
a new car. Of course you do!
If your low pitch roof is shingled, that could be the prob.
A pitch of 2-3 needs at least a three ply hot tar mineral felt
application, as shingles will leak.
I would wait till it gets really dry outside, then carefully sweep and
inspect the joint between the roofs. Tiny cracks can admit water when it
is backed up by a snowmass. You may just need to sparingly trowel on
Henry's plastic roofing patch compound, or similar cold roof patch. In
winter, get up there and sweep off the snow when it gets backed up, then
reroof only as a last resort. Such junctions almost always leak, and they
are a real downside of low pitch additions.
