Copied from an old post while researching the subject of cleaning the roof. This may be good info for us new folks.
Hi all,
I saw some posts over at rv.net discussing cleaning of trailer roofs. Some of the discussion suggested using Murphy's Oil Soap on the roofs.
Do not use this for your EPDM Rubber roof on your Heartland trailer.
From what I have read elsewhere, Murphy's Oil Soap can be used on TPO roofs (don't quote me though - do your own research if you own a TPO roof).
I spoke to Scott at the factory and confirmed with him that the EPDM rubber used on Heartland trailers is made by
Alpha Systems, Inc. in Elkhart, IN.
EPDM stands for Ethylene Propylene Dien Monomer.
At the bottom of this post is more information on EPDM but first, here's what Alpha has to say about maintenance of EPDM roofs:
Cleaning and Maintenance of Alpha Systems Royal Roof EPDM Rubber Sheet
Proper care and maintenance of the recreational vehicle, including the Royal Roof, is important for trouble-free performance. Normal maintenance is simple, easy and requires no special materials.
Periodic cleaning three or four times a year is the primary maintenance required. Alpha Systems suggests using a household cleaner such as Top Job®, Spic-N-Span®, or Ajax® Cleanser. Granulated cleaning products perform better for cleaning EPDM. Since the surface is not smooth like fiberglass, a medium bristle scrub brush should be used instead of a sponge. The rubber membrane requires scrubbing much like a white-wall tire does. For tougher stains, like those from oak leaves or pine sap, use kitchen cleanser with bleach. ** Extra precautions need to be taken to control runoff onto sidewalls when using products containing bleach.
After cleaning, rinse the roof and sidewalls of the RV completely to remove any soap residue and to prevent streaking.
Quarterly inspection of the roof is highly recommended. Check the membrane for possible damage and check the caulk/lap sealant used in all termination areas and around all accessories and fasteners.
Alpha Systems Royal Roof EPDM is quite inert and will dependably resist weathering. It can, however, be cut or punctured by sharp objects. If damage does occur, the Royal Roof membrane can be easily patched. Use caution when placing any articles on the roof and exercise extreme care and caution when working on top of your vehicle. The Royal Roof may become slippery when wet, so remember to exercise extreme caution when cleaning the rubber membrane.
EPDM rubber does not require periodic application of any product to protect it from UV light or ozone. Such products can often damage the EPDM membrane. Protect-All® Roof Treatment for EPDM rubber roofs, 303® Protectant for EPDM rubber roofs, or other products compatible with EPDM rubber roofing may be safely used. If you have any questions about these products, please call Alpha Systems Customer Service at (phone number) for assistance.
! DO NOT USE ACETONE OR ANY PRODUCTS CONTAINING PETROLEUM DISTILLATES ON THE ROYAL ROOF !
