What are the do's and don'ts for maintaining my rooftop terrace?



  • Visit and inspect your rooftop terrace on a frequent basis. We suggest monthly, at the very least. 
  • Clean spills and potentially damaging substances immediately. This includes tree sap, tannin stains from leaves and rust. 
  • Clean your rooftop terrace four times per year. 
  • Use a soft-bristled push broom or leaf blower to remove loose dirt and debris. 
  • You will not need any soap or cleaner to clean the vinyl membrane. Just some water and a gentle-bristled brush. 
  • Scrub in a circular motion with warm water and the gentle-bristled brush to loosen dirt from the surface.  
  • Rinse and allow to air dry. 
  • Inspect your deck twice a year for routine maintenance needs—especially the areas with caulking—and reapply urethane caulking if needed.  
  • Inspect exterior doors and thresholds for signs of dry rot. Caulking and paint should be maintained on a yearly basis to protect your exterior door and home from water intrusion.  
  • When placing furniture and potted plants, avoid sharp edges. Use pads on furniture feet, saucers under plants and remember to occasionally move furnishings to prevent indentations in the vinyl membrane on the floor of the rooftop terrace. 
  • Use carpets or mats on the surface. Make sure they are non-rubber backed or backed with polypropylene. Ideally, move rugs around occasionally to reduce color differences from long term sun exposure. 
  • When using a barbecue or grill, be sure to place a non-rubber backed mat underneath the grill to catch spills. 
  • If it snows, use a plastic snow shovel to remove snow from the rooftop terrace. Be sure to avoid any shovels with sharp metal edges. 
  • Inspect and clean debris from drainage scuppers. As part of your spring and fall general maintenance, verify openings are free of yard debris. 



  • Drag heavy or sharp objects across the surface of the vinyl membrane. Cosmetic damage and minor scuffing can usually be addressed with a white or rubber gum eraser. 
  • Use the surface as a work area. For example, no cutting, dragging or sawing atop the vinyl surface. 
  • Place a Dutch Oven or other heat source, such as the hot lid of your charcoal grill, directly on any vinyl surface. 
  • Place metal objects directly on the vinyl membrane. Rust has the potential to permanently stain the flooring of a rooftop terrace. 
  • Use harsh cleaners. 
  • Use silicone, asphalt, bitumen or rubber-based products in conjunction with the rooftop terrace. All the substances are incompatible with the vinyl membrane and can cause long-term staining. We recommend urethane caulking and polypropylene backed mats.
