If you can, it is a great idea to empty off your deck for winter. With having your patio furniture under the deck or somewhere else it makes it easier to shovel off the snow from your deck in the winter.
" Just want you to know how much we are enjoying our deck and patio cover. Rain or snow no longer hinders my love of barbequing. We're proud to show off our new deck — you too should be proud of your workers who did an outstanding job! Thank you and we will happily recommend you to our friends and family. "
