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
(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'.
Thanks in advanced!
I had the same problem and went with the 'inner tube' approach and put
the rubber stuff on and am very happy with the results. This stuff has
a long and excellent track record in commercial use. It is not the
prettiest looking roof [shingles are not attractive either after a few
years] but beauty is in the eye of the beholder and no leaks are
beautiful to me.
This is Turtle.
The Rubberized roofing is the best , but in my words it must be Brier Roofing
material. Brier Makes Black untextured and textured [ colored ] roll roofing
stuff. They have a 20 years warranty on it and if it fails or leaks but must be
installed correctly. they come and fix it material and labor for nothing. These
repair do include hail damage.
Could not find "Brier Roofing" on the net. Is it spelled right?
As for sweeping snow off the roof. Well, call me lazy, but I'd rather
not and seeing how I may be selling the house in a year or two, it
would be hard to sell the house w/ the disclosure that one has to sweep
the snow off the roof every time it snows. Mind you I don't see much
ice damning per se, but ice does form and I guess some of it is getting
under the shingles and through any ice water shield there is.
thanks for everyones comments. I will likely go with option 3. And
hopefully get the best of both worlds.

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
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.
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.
Yes - I had it installed on a low slope roof on my last house (Shed dormer
out the back of a cape cod style house. I was so impressed that I installed
it on a cottage I own and did it myself for two other cottages. It is
available with granules so it looks like regular rolled roofing except it is
good for low slopes.
I'm not sure this will completely address the original posters issue though.
Most likely the problem is at the intersection of the regular roof and the
low slope. Anther poster pointed that out as well.
