CLEANING AND MAINTAINING
SUPERFLEX ROOF MEMBRANE
Proper care and maintenance of the Super Flex roof membrane is critical to sustain years of trouble-free performance. Normal maintenance is simple, easy and requires no special materials.
Periodic cleaning (three to four times per year) is the primary maintenance required. Alpha Systems recommends using a non-abrasive household cleaner, such as Dawn dish soap or Spic-N-Span, and a medium-bristled scrub brush. Do not use any harsh or highly-abrasive products during routine cleaning. When finished cleaning, remember to thoroughly rinse the roof and sidewalls in order to remove any soap residue and to prevent streaking.
CARE SHOULD BE EXERCISED WHEN WORKING ON TOP OF YOUR UNIT! THE ROOF MAY BECOME SLIPPERY WHEN WET. DO NOT USE ACETONE, OR ANY OTHER PRODUCTS CONTAINING PETROLEUM DISTILLATES, ON THE SUPER FLEX ROOF MEMBRANE. USE OF THESE PRODUCTS WILL DAMAGE THE MEMBRANE.
Periodic inspection of the roof, during cleaning, is highly recommended. Check the membrane for signs of damage. If damage does occur, the membrane can most often be patched (refer to the Care and Repair Instructions).
The Super Flex membrane is quite inert and will resist weathering well; nor does it require the periodic application of products to protect it from ultraviolet light or ozone. In fact, these products can often cause damage to the roof membrane.
While inspecting the roof during cleaning, it is also important to check the lap sealant used in all termination areas. Inspect the existing sealant around all accessories and fasteners for signs of cracking or voids.
If an additional sealant is needed, you can purchase Super Flex sealant at www.campingworld.com. Please note ONLY SUPERFLEX BRAND SEALANTS CAN COME IN CONTACT WITH THE SUPERFLEX ROOF MEMBRANE.
