I live in the pacific northwest and just purchased a home on the beach. It gets hit with salt water spray, and some heavy windstorms. It needs a new roof and I am trying to find out what type of roof I should do. The main concern is what is going to last a long time in a salt water environment.
The existing roof is around a 1:12 slope (almost flat). It is a torch down.
I have been looking at metal roofs, TPO, PVC, and here is what I have heard.
TPO roof in salt water enviroment - will last about 10 years. $14k
Gavalume - will rust and eventually fail , 30 year life expectancy. $16k
Aluminum painted with Kynar paint - 20 year warranted system, life expectancy maybe 35 years - $24k
Copper Roof - no data yet. $32k
Follansbee TCS II (Stainless Steel Terne Coated) - 30 year warranty, 60 year life expectancy. $35k
i want something where I am going to get the best bang for my buck but also that will last a long time, since I don't want to do this again in my lifetime. Anyone have any ideas here, other options, real life experiences, let the discussion begin.
