Hello, I'm a new 'member' and I like what I've been reading.
I've been asked to look at a 'problem' roof.
The roof that appears to be about a 2/12 or 3/12 pitch. It is currently roofed with a cold install modified 'rubber roof'. The roof apparently had this same type of roofing material installed previous to the current roof. The previous roof was appox 4yrs old but leaked and was replaced 2 yrs ago with the same type of roof per the suggestion of the roofing contractor. (???)
The low-pitch roof meets at the peak with an approx 8/12 pitch roof. A roof-vent is installed with the membrane roof side "blocked" . This apparently was to stop water from blowing, or backing up into the vent and inside the home from the low-pitch side.
There are rafter-vents installed underneath this low-pitched roof, and the 8/12 roof, and insulation installed, but the inside is not 'finished' with drywall or other material. The rafter vents/insulation end at the outside wall, and the roof over the eave is uninsulated and 'vents' to the rafter vents. This *attic* is heated in winter and cooled in summer and is used regularly as a 'storage' area. The eaves are vented but not as much as "I would like".
With the nasty weather as of late the roof is leaking. It is leaking into the eaves and there are ice-cicles hanging out all of the vents in the eave. It appears that the leak(s) are at the drip-edge or close to it since there appears to be no leaks inside the attic itself. There is an ice dam on the last 3' of this roof.
The roof appears to be installed 'correctly' with only a couple 'pops' in a seam here and there that don't appear to be leaking (from inspection inside). I can't see what is underneath the rubber membrane. I can't see the last 3' of the roof due to the ice/snow.
This problem is the SAME problem that the previous roof had, and I'm wondering about using an ice/water guard under modified roofing. Also, I suspect one of the seams may be leaking farther up the roof, and if there is roofing paper underneath, the water may be running over this all the way to the eave .
I'm wondering what roofing material best suits this job. I'm also wondering if the roof is vented enough to keep the roofing material from being 'cooked off' and/or damaging the seams. Under the right conditions, ie-lots of snow with no wind followed by warm/freeze cylces, a huge ice dam could develope and pose a huge problem at the peak, or a weight problem. I'm wondering if a roof de-icing system is needed.
