Our customer had a very low roof line and needed a strong awning that could hold up to wind inherent with the ocean front location.  We decided to use the NuImage g250 Retractable Awning for its strong construction and it's sleek profile design with no valance.  Mounting the retractable awning on the roof gave us plenty of head room, so they can entertain and enjoy their deck without worrying about the awning height. We added a wind sensor for extra protection (the customer was cautioned and well informed about wind sensor limitations -ask your Breslow salesperson).  The roof is a great place to mount an awning if you want to create a little more height from the roof of the awning. This roof mount came out beautiful.
