Anchoring an outdoor table on a rooftop deck is essential to prevent it from tipping over or shifting due to wind or movement. Here are the best methods to ensure your table stays firmly in place:

1. Use Weighted Bases or Sandbags: Attach sandbags or weighted bases to the table legs. This adds stability without permanent modifications.

2. Install Ground Screws or Anchors: For a more permanent solution, use ground screws or anchors designed for decks. Drill them into the deck surface and secure the table legs with straps or brackets.

3. Utilize Bungee Cords or Straps: Loop heavy-duty bungee cords or straps around the table legs and attach them to nearby railings or fixed structures.

4. Opt for Windproof Table Designs: Choose tables with built-in anchoring systems or perforated surfaces to reduce wind resistance.

5. Add Non-Slip Pads: Place non-slip pads under the table legs to minimize movement, especially on smooth deck surfaces.

By combining these techniques, you can enjoy a stable and secure outdoor table setup on your rooftop deck, even in windy conditions. Always prioritize safety and durability for long-term use.
