Deck Roofs

Many decks feature a roof for sun and rain protection, built from materials other than normal roofing materials. Corrugated and other fiberglass roofing work fairly well and require a minimal slope, but will deteriorate in three to five years due to the ultraviolet rays of the sun. Similar effects can be seen with other plastic materials.

Awnings are made from a variety of materials. Standard canvas deteriorates after a few years. The vinyl-impregnated variety tends to last longer. Many of the retractable awnings use a woven synthetic material which tends to have a somewhat longer life than most of the other awning materials.
