We are working with an architect on a one level, 1650ft, vacation home that will have a simple rectangular roof sloped at 1:12, R50 spray foam insulation. It will be located in the midst of a number of oak trees. In this area there are frequent winds, it is hot and dry during the summer and cold during the winter with not a lot of snow. One priority is that the roof be built to last and avoid the need for maintenance to the extent possible. The architect is suggesting Taylor Rusteel Plus 22 ga, M200 (A606) standing seam that will be mechanically seam sealed with a Polyglass polystick MTS / MTS PLS underlayment. Are oak leaves going to mess with a roof like this? I’m not keen on the idea of getting on the roof to clean it. Is this going to take the wind well? Thanks, Carl

Anything at that low a pitch with a bunch of trees above it is going to have debris and possible staining on it. Metal, without question, gives you the most durable and significant roof to resist that and allow for easy cleaning.

Thanks for your reply. I’m definitely going with a metal roof, my question is really with the type of metal. Is a Corten (A606) 22 ga product going to stand up as well as a painted 24 ga product? Everything comes with trade offs, I’m just trying to make sure I understand what they are in this situation.

Is this product you considering a completely unpainted or finished material? I think the more finished the surface, the less porous the substrate and the easier to clean.

I just spoke with Taylor metal and the Rusteel Plus is an uncoated material. They do not have a guarantee for this type of roof. While the theory is that after Corten rusts the properties of the metal then stop further corrosion there are factors that can allow corrosion to continue. Hence my apprehension with the oak leaves, would that be a factor or am I over thinking this? I know a 22 ga metal roof is goning to last but am I trading a 100 yr roof for a 25 yr roof or a 90 yr? Also it would have poorer performance with heat absorption.

Why not just galvanized or otherwise coated roof?

Exactly. Talk to me. This is a situation where I am weighing the merits of a particular look that will cost me perhaps in terms of performance versus what? I like the rusted farm shed natural look that the Rusteel Plus A606 would produce but I’m also trying to think long term. In your opinion what is the most robust and energy efficient option (that’s roughly in the same league cost wise)?
