I needed something to protect my patio furniture from the elements so I decided to buy the Arrow Buildings Patio Cover. I was very thrilled that all of the parts and pre-drilled holes lined up perfectly. Installing the cover was simple,m but it was a two man job. It took me and my brother about a week to complete installation, but it could have been completed in 2-3 days if we had more time. Since installing this patio cover I have spent almost every evening on my back deck. This cover has provided excellent shelter from the rain and the sun. It also has served as a temporary storage open space when I'm doing work around my yard. While under this cover the temperature is about 15 degrees cooler during the summer. Also this cover has performed very well against snow and only shows slight signs of wear after a couple of seasons. I would definitely recommend the Arrow Building Patio Cover because it provides excellent shelter and transforms a backyard to a stylish getaway.
