I have a 4;12 pitch on a single wide 2001 mobile home and am thinking of going metal. Currently a shingle roof. Most roofers are telling me that metal will shed the snow 'garuanteed' and a few people are telling me that it will not shed snow all that well due to the pitch. What is your opinion - will it shed snow and avoid the ice build up that I am seeing with my shingle roof?

It probably will shed faster than current but if the ceilings are not well insulated you could still have ice damming issues potentially. Make certain that the product you select is appropriate for the pitch of your roof. Todd Miller

Thank you. I currently have some 'round can vents' in the roof but there really is not at attic so the air space is basically the width of the truss. In essense, the interior ceiling follows the same pitch as the roof itself. We are looking at a ridge vent along the top based on roofers recommendations. Do you see that as a more effective means for ventalation (for ice buildup) that round can vents can offer in this situation?

Yes, but proper ventilation also requires intake vents at the bottom (eave) of the roof. Todd Miller

The metal will be ribbed every 9 inches with ribs that are approx 1 1/2 inches in a triangular shape - the thought being to allow air to come in thru the eaves (under the metal) and run up the ribs to the top of the roof. It should stabalize the metal temp somewheat to help avoid the ice build that the shingled roof caused.
