Ice Dams

[Bob]

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

Im curious, do you have a single wide with cathederal ceilings? What is the approx pitch of your current roof? Probably a more permanent fix would be to add roof vents. Just some thoughts. Tom

Tom, I have a double wide. Full width ridge vent and soffit vents. Others on the forum mention the possibility of both the ridge vent and soffit vents being blocked. I am going to remove the fascia trim and drop the soffit screen to see if there is any blockage there. I am however reluctant to remove the ridge vent. I have a 3/12 roof pitch. I've talked with many people who have had great success with the heat tape especially used with the auto feature that senses the temp. and turns on and off accordingly. Thanks for your interest.
