Sent you a DM.

It would be a straight forward job... no crazy intermediate parapets.

I'm getting the quote later today or tomorrow... I'll let everybody know the results.

I'm hoping that escalation in pricing has dropped-off, but I doubt that the roofing market in NM has really cooled down very much. El Nino and all.

Flat metal roof?
Lasts a long time, maybe even lifetime?

I've never really heard of a flat metal roof. How does it work?

It would have to be standing seam or it won't work. metal deflects and duck ponds.

Go with white or whatever is traditional in the market on the membrane. any heat gain from a darker membrane will be blocked by the insulation.......creating thermal problems (not to mention UV problems) and probably shortening the effective life of the roof. If you are running refrigerated air (why not evaporative? operational costs are far less) you would be better off making sure the duct work is tight and leak proof.

I would have preferred a Swamp Cooler, but it's not my house.

Retrofitting Flat Roofs with Sloped Metal Roofing

http://frontierassoc.net/greenafford...fs%20final.pdf

Structural roofing will not puddle up.
All of these metal roofs have to have a slope. If you wish to re-engineer a flat roof and add a slope to it, that is fine.

"A minimum slope of 2/12 is mandatory for most metal roof panel profiles; however, a steeper slope can be used."

A slope to any roof is good, because it will rain at some point in time.

One of the links I provided has a retrofit pre-manufactured slope grid (ready-made trusses) that is easily installed, then covered with metal.

I have owned homes w/flats and they're nothing but trouble. tar and chip, membrane, rubber, they all deteriorate and will leak over time.

A metal roof is forever.

The money that could be saved is enormous, over tar, chip, membrane, rubber.

Once the trusses are installed, and covered with metal, there is very little, if any maintenance required.

Of course the manufacture is going to recommend "easily installed ready-made trusses". Truss's to cover approximately a total of 1,700 square feet is not necessarily an "easily installed", cost effective idea in my opinion. The appearance of the house will definitely be changed.

But you originally stated:

IMO
I'd consider metal as an option.
If one considers the cost of constant maintenance of the other types, metal will last longer and will be virtually trouble free.

One does not have to purchase the trusses, a good carpenter can build trusses, or, use a rafter system, which I have done before. The other option is to have the roof measured and have engineered trusses built by a lumber supplier and have them deleivered. Trusses, when placed on load bearing walls will last and last when covered with metal..

My ideas are only suggestions for someone to consider, and as long as the owner is paying the bill, he/she could have it done the cheapest way, or, spend some more money and have something that will be appealing and longivity.

It's sort of like when people rehab a home. If floors are bad, and need replacing, sometimes they'll use pressboard for sub flooring, while other might spend more money and put down exterior grade plywoods or hardwoods.

It's the cliche', pay now, or pay later. Cheap isn't always best. The buck stops with the owner and what they decide.
