This is a nice almost maintenance free patio cover and deck we built in NE Portland, the only maintenance is yearly cleaning. The decking is Timbertech Terrain Brown Oak decking and the patio cover is an aluminum and acrylic patio cover. The patio cover is made by Acrylite and has a ten year warantee, it has a dual wall acrylic roof panel that lets light through while reflecting heat. The framing of the patio cover as well as the railing is all powder coated aluminum so it will last a lifetime. In our opinion this is the best patio cover and decking combination you can buy!
