The Manufactured Housing Forums

In the late summer early fall I am planning to have heat tape installed on both the front and rear edges of my home. I have an horrific problem with ice dams. I have a full length ridge vent along with 9 inch vented overhangs front and rear of the home and still get damming. I have 48 inches of water protection and have not had any problems with water entering the home as I shovel the complete roof and steam channels every snow event. I have gotten several estimates on a metal roof but it would be a sin to tear up a new architectural roof so early in its life. Wanted to get some feed back regarding this option or I'm I missing something with the proper ventilation of my 3/12 roof cavity.
Thanks in advance for any assistance Bob

Sounds like everything is just right. Have you inspected the area immediately above the eave, for the required one inch of clear air flow. Could the insulation be hampering the air flow in this area, and allowing the ice dam? I've had to remove the top of a vent to provide access, and then use a light and hand mirror to see into this area. Good Luck.

Ray is right. The roof insulation is most likely blocking the roof ventilation or the ridge vent is blocked. Both of these are common in manufactured homes. That you have to shovel the snow from your roof is crazy. Don't get hurt!

Thanks Roy, Tomorrow I am going to remove the fascia trim and drop the soffit screen to check for blockage. Thanks for you interest in my dilemma.
