Just purchased Mobile Home with Metal Roof. Have Concerns | Ask The Experts Forum

Russ Keller 5/11/2016	Hello all, I just moved into our mobile home here in New Mexico. The previous owner put a metal roof on the house himself. Before i purchased, I took a look at the roof and it seemed like he did a decent job other than he covered all of the vents for kitchen and bathroom exhausts. Anyway, I missed a glaring possible issue. It looks like there is 2 layers of asphalt shingles under the metal roof. Do you guys think this is too much weight? I am noticing creaking on the floors when I walk in the house in different locations. Originally, I chalked this up to the age of the home (Built in 1995). Being I just moved here, I do not know what the winters are like. I know they get some snow but nothing like back in Wisconsin where I come from. Also, the pitch of the roof is 12/3 if that helps. Thanks for reading, mavruss	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21203/find/
Todd Miller Isaiah Industries, Inc. 5/11/2016	Metal roofs are generally very low weight. I assume this is a steel roof so it has a weight around 80 - 90 pounds per 100 square feet. Asphalt shingles weigh from 275 - 425 for the same area. Only a structural engineer would be able to make a determination (based upon joist inspection) but I am guessing you are okay. The layers of shingles had lost quite a bit of weight in evaporated oils and worn-off granules in all likelihood, so that helps considerably with the overall weight.

Russ Keller 5/19/2016	Thanks for the input guys. New development. Looks like the main seam that joins the two halves together are lifting up on one end of the home and Im seeing cracking in the ceiling mid home. Thought maybe its foundation so I put a level on my floor and its level. Is it possible that the roof weight could be lifting up the flooring?

Todd Miller Isaiah Industries, Inc. 5/19/2016	I really have to refer you back to either the manufacturer of the home or a structural engineer. I certainly have never run into anything like this before.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21207/find/
Eric Novotny An informed customer is the Best Customer! 5/19/2016	+1 to Todd's comment Russ. You really need to just get an engineer to look at it. Regardless of the roof application, I cannot see a reality where the roof would create that scenario in the home.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21208/find/
