Vents

Return to I Have An Existing Metal Roof and Have A Question

Return to Forum

We are fixing to put a metal roof over our doublewide. We have hired someone to do it for us. We asked about buying new vents to replace the old rusted one. He said he was going to cover them up. That the new roof will be above them. Is this safe? We also have gas hot water heater that is vented out of roof. Is this safe to cover all the vents??? Please let me know ASAP he is going to start this week. 5/1/2011

I am not sure exactly what your contractor is proposing but generally speaking vents should never be covered. Doing so could be dangerous for the home or even its occupants. It also likely would violate building codes. Todd Miller

Thank you sooo much. He was telling us that he is going to go about 1 to 2 inches above the vents. My husband is going to ask him just what he plans on doing. He said it will be like a whole new roof. Just a little scared to cover up gas vents. He said it will vent out the ends. I really think we need get someone else.

I will say that this may not mean he can't put on a good roof. It sounds like he does not want to take the time to flash around vents. It can be tricky. However, again. this sort of thing violates building codes and can lead to an accumulation of moisture or perhaps gasses. Todd Miller

I agree! I'm not a fan of gas anyway. I think we are going to tell him we want new vents or we going to have to find someone else. Thank you for your help.
