We need a new roof put on and cannot decide between the Galvalume steel or Aluminum. The cost is less for the steel but we are concerned with rust as the house is on the beach in the panhandle of Fl. Would the location void any warranties?

Mary, Thanks for your interest in metal roofs. Metal roofs have the benefit of excellent resistance to wind uplift needed in your location. In a corrosive environment, like beaches adjacent to salt water, aluminum is expected to last longer than steel due to its superior corrosion resistance. Experience shows that steel is compromised by corrosion sooner than aluminum. Typical steel roofing warranties exclude coverage on buildings adjacent to salt water. Warranties vary by manufacturer, so it is a good idea to review the warranty for any material you consider purchasing. Regards, David Stermer

Just as David said, check with each manufacturer for their specific requirements and exclusions. What type of panel were you looking into? Regardless of material, metal is going to be the right choice.

Thanks for your feedback. I had not thought of what type of panels yet. Do you recommend one?

Mary, There are lots of good products on this website. Many of the manufacturers offer products in both steel and aluminum. You may want to consider a product with concealed fasterns rather than exposed ones. Other than that, a lot comes down to whether you like a vertical seam look or perhaps a shake, shingle, or tile facsimile. Thanks!

I would also like to use metal on my beach house, but the wind here (Playas, Ecuador) is constant and the contractor will not guarantee the product (Rooftec master pro) within a mile from the beach, although they initially told me that the product was used on lifeguard shacks. I need to cover a concrete slab roof. I'm tempted to go ahead without the warranty but would appreciate your suggestions.

I have not had a lot of experience with concrete decks. I wonder if there would be any way to secure the roofing with spray foam as well as with fasteners?

Thanks, Todd. The roof is concrete but it is pitched with gables, a standard practice here where tropical insects eat all wood. The issue for me is rust more than fasteners. Will these roofs rust quickly where there's a lot of salt in the air (waves and wind)? Thanks

I really would suggest stainless steel Fasteners. You could also consider an aluminum roofing system.

+1 Stainless or aluminum and it is a a non issue. Stainless will certainly be more expensive but aluminum is not usually that much of a premium.

Hi, I also live on the beach in Crucita, Ecuador. I have a concrete roof now, 2 years old and leaks like a sieve. We are currently looking at all options. I know it's been a few years since your post, but I was wondering what type of roof you went with. How is it holding up to the salt air? It has been suggested that we could consider ceramic tile. Our roof is also very angled, pitchedand gabled.

An aluminum panel roof will hold up quite well in your climate and conditions.
