How Often Should I Clean My RV's Roof?

It is recommended that you clean the roof at least 2 to 3 times per year. LaSalle Bristol membranes do not require any special cleaners for maintenance. You can use typical household cleaners - something non-abrasive, used with a medium-bristled scrub brush. It's also a good time to check the seals around the rooftop accessories and edges of the roof. If you find damage or something that may compromise the integrity of the structure, you can apply more sealant until it is either time to take something down and reseal it entirely or time to replace the whole RV roof.

How Often Should I Replace/Reseal My RV's Roof?

Most RV roofs will last around 20 years, but after about 10 years, it's a good idea to start looking closely for leaks, cracks, or other damage that may lead to replacement of the entire roof. For the best results, and the longest-lasting roof, it's best to check the seals and edges of the rooftop at least once a year.

How Do I Replace My RV's Roof?

You will need a few tools to install the membrane on your RV's roof. These include butyl tape, adhesive, sealant, a neoprene head squeegee (for no streaks in membrane surface), and a utility knife.

To begin, remove all your rooftop accessories - A/C units, vents, fans, etc. - and clean off the rooftop. After you have applied the adhesive and laid the membrane flat, squeegee out the air bubbles that will inevitably form, and cut off any extra material hanging from the sides of the RV. Using a utility knife, cut out the areas where your rooftop accessories will be installed and place them in their respective positions. From there, you can apply butyl tape, self-leveling sealant, and non-sag sealant to finish off the installation process.

Replace or upgrade your RV roof with this lightweight, rubber roofing membrane. Elvaloy-based PVC material is puncture- and tear-resistant. Flexible design makes it easier to install than other roof membranes. Measures 35' x 9-1/2'.


Great product installed easely used it twice more on two other trailers. Highly recommended


Though the project as a whole was more prep than expected. The roofing goes on easy using the LaSalle PVC glue and sealants. The roof looks great and has been from Indiana to Utah , Wyoming and back with no issues. The expected ease of repairs if needed will also be a plus if that time comes. The plus of no need to clean the roof is nice too. Great product highly recommended.

    I checked with my roof installer, and got a hold of a sample of the LaSalle Bristol # 3441700534142711435 myself, and found out that either side can be glued down. There is no up or down. Both sides are identical. This membrane is glued down with # 344270341415 adhesive. I have attached a video of an installation. Be sure to order the correct length.

  • RV Membrane Replacement for Forest River Flagstaff 2013 8528IKWS
    The SuperFlex membrane your Forest River came with is a different style than the LaSalle Bristol XTRM part # 3441700534142711435 that you referenced but that doesn't mean this wouldn't work. It's just a different style. We have this membrane as a kit that includes sealants and butyl tape with part # 344270KIT35 which would come with everything you would need to install the membrane. I attached an install video link to this page for you to check out as well. The color is white.

  • Comparing Alpha Systems Superflex and LaSalle Bristol RV Roof Membranes
    The Alpha Systems Superflex RV Roof Membranes like part # AL42CV uses a TPO membrane and the LaSalle Bristol RV Roof Membranes like part # 3441700534142711435 uses a PVC membrane. The TPO membrane is more resistant to punctures and wear but the PVC membrane is more energy efficient. These are the main differences but they both work well on RV's. I recommend the TPO due to the increased strength which would therefore mean less maintenance. I have attached a full list of options below.

  • Ratio of Non-Sag and Self Leveling Sealant of Alpha Systems RV Roof Replace Install Kit
    The proportions of what comes with the Alpha Systems RV Roof Replacement Installation Kit for Roofs Over 26' # AL74UV was designed based on the same proportions of what you'd use when installing the roof. Self leveling sealant serves the purpose of leveling itself totally flat before curing which is great for on top of the roof whereas the no sag is great for the sides where you want it to hold it's shape after you apply it.

  • How Many Tubes of Sealant Are Needed to Complete Installation of LaSalle Bristol XTRM Roof Membrane
    A typical 10 oz tube of sealant will cover approximately 50 linear feet but this can vary depending on the bead size. I recommend measuring all the areas of your trailer that will require sealing so you can determine how many tubes your project will require. A convenient option to consider is the LaSalle Bristol XTRM RV Roof Installation Kit # 3442703414KIT. Not only is this a more economical option than buying everything separately, this kit will take most of the measuring and guessing...

  • Should Old Sealant be Removed Before Installing LaSalle Bristol XTRM PVC RV Roof Membrane
    You do want to remove all of the old sealant before installing the LaSalle Bristol XTRM PVC RV Roof Membrane - White - 35' x 9-1/2' # 3441700534142711435. While I know it can be a pain, some patience and a putty knife will go a long way. If some of the plywood comes up a bit while you're doing it, that's okay! You can fill it in with non-sag sealant, the LaSalle Bristol XTRM Universal Non-Sag Sealant for RVs # 344270341438-1. Finally, to finish the install you'll also need the LaSalle...

  • Best Way to Protect Fiberglass Roof on Pop Up Camper with Fine Hairline Cracks
    When it comes to applying solutions we have the RoadMaster Voom Gold Auto and Marine Polish # RM-9940 but this is more for making your roof shine, not necessarily fixing damage. I took a look at the Dicor coating you mentioned and it looked like some of the reviews said that it didn't work well for the hairline cracks that you mentioned. Your best option would be to add a LaSalle Bristol XTRM Roof Membrane. This basically sits on top of your roof and becomes your new "roof". The material...

  • Recommended Sealant for Metal Roof on Atco Trailer
    The LaSalle Bristol XTRM sealants are what I recommend using for sealing up the metal roof on your Atco trailer. For a white sealant you will want to use part # 34427034145-1 for horizontal applications and part # 344270341437-1 for vertical applications.

  • Recommended Slide-Out Roof Repair Kit And Installation Video
    Most slides have EPDM rubber roofs but because EPDM is rubber it requires treatment each year to keep it soft and prevent shrinkage. You could replace it with TPO which is another synthetic rubber that will last longer than the EPDM. The smallest roll we carry is the Alpha Systems Superflex TPO RV Roof Membrane - White - 67-1/2 Sqft Item # AL68CV which can be cut to fit and you'll need some adhesive # AL27CV and sealant # AL28KV to install it.
