Installation Tip: Speed & Precision with the SkyJack Drill Bit and Hand Tools
For fast, accurate pedestal height adjustments, use the SkyJack Drill Bit Tool to quickly dial in elevation with a cordless drill—perfect for large or time-sensitive installs. Then, use the SkyJack Hand Tool to fine-tune pedestal height from above without removing pavers. This combo saves time, reduces labor, and ensures a level, professional finish across your rooftop deck.

    We had a great experience with Skydeck USA. Their team was extremely responsive and easy to work with and the customer service was excellent from start to finish. The Shop drawings were clear and helpful, which made the whole process go smoothly. Best of all, the finished roof deck looks amazing. We couldn't be happier with how it turned out. Highly recommended!!

    This is a far superior product to the other major brand. No cutting of pipe necessary. Skydeck did a great job with the layout and providing all of the items needed. Also, I found the skydeck pavers to be better than the locally aqured pavers. They are more consistant in thickness and have a less textured bottom. This leads to a flatter cleaner top surface. And to top it all off, I was able to speak with the owner of the company who was VERY helpful in the whole process. I highly recommend using Skydeck :-)
