Waste of time or not

hi like all the post onice an water shield the contractor wont to put it down on my shingles and 30pd felt before we add the tin its a trailer house with not alot of slope an an adition and the wind keeps blowing the shingles off we get hard winds in nevada

Put on ice and water. Felt won’t help you much on a low slope roof.

They want to put the Ice & water shield over old shingles…

A synthetic underlayment is the best choice for this application.

Woops, missed the shingles. They’re going to put metal roofing over existing shingles? That is a bad idea.

Wood sleepers by themselves is all that is needed.

I’d be careful in a high wind area. The Reno Nevada area, for example, often has sustained winds of 100 mph or higher. Metal on sleepers or shingles could be a problem.

I would forget about shingles/Metal and invest in some concrete tile.But living in a trailer you would need reinforced roof structure and probably some foundation and wall strengthening.By then you could have a different house.

I would keep the shingles and install your roof according to the Florida Building Code Miami Dade and install the shingles with a mansard nail pattern forget the felt and install the moisture guard directly to the decking then install the shingles to the MG.

Then your worries about lost shingles should be a thing of the past.Losing the entire roof decking and all would seem a reality versus single shingle blow offs.

donl I almost flagged that comment of yours for spam.lmao :badgrin:

I think you are saying your contractor wants to put ice and water shield with 30pound felt on top? Sounds totally bulletproof to me!!
It doesn’t get any better than that for an exposed fastener metal roof.

If it was standing seam metal, than i dont think that is neccesary.

I’m with Roofmasters opinion-I would install shingles and install the shingles with a mansard nail pattern forget the felt and install the moisture guard directly to the decking before the new shingles
