2 Roof Layers On Manufactured Home

I m looking for any other explanations to explain this.

2 roof layers on manufactured home.

I was call out to inspect a manufactured home roof 2000 yr gable 3 tab 3 12 slope for insurance reasons. 3 tabs are less expensive but also less durable have lower wind resistance and have a flatter appearance. Additionally it prevents wind driven rain from getting under your shingles and causing damage to your roof structure or the inside of your home. Will this ad too much weight to the roof structure.

The roof seems to be solid and the home is taken care of. It a appears to be from wicking back under the shingles. Two layers is usually all they do. 2 roof layers on manufactured home statements were made that multiple roof layers are not allowed on these structures.

Yup too much weight. Some day you are at home depot try picking up just one bundle of shingles and you will realize how many thousands of pounds of shingles you have on your roof. When a buyer is purchasing a home their homeowner s insurance carrier will inquire about the age of the roof and the number of layers. Some roofing experts say you can do on manufactured homes that have 2 4 studs 12 16 oc and roof trusses that are 16 oc or less.

2 layers of shingles on a mobile home post by eugene wed aug 03 2005 8 56 pm also the roof trusses are designed for a dead load of 8 lbs per square foot a second layer will exceed that dead load maximum. I found that the first 1 to 2 feet from facial board on the west side was rotten. There are a few things that you should consider about asphalt shingles. Considering the fact that most manufactured homes have smaller sized lumber for roof rafters and then probably 1 2 or less thickness for roof decking plywood or o s b i would not add anymore weight to the roof.

On site built homes two or three layers of shingles are acceptable but on a mobile home only one layer is permissible. If you have an asphalt shingle roof. The home is 14ft wide and doesn t a long roof span on each side. Has anyone come across this on a mh.

There seems to be a split in opinion on layering the new shingles over the old. Others roofing experts have told me they won t do it on any manufactured home. Thanks for any help.
