Roof Maintenance/Coating

[BlackHawk69]

Time for adding a new coat to the roof of my Keystone Cougar and seal any cracks along the cap and other area where water can seep in. Roof is light tan. What recommendations do you have and what products are the best for the price?

Year of trailer?

2016 or newer no coating is recommended. It is an Alpha TPO membrane. Here is what the manufactor says:

The Alpha roof membrane is quite inert and will resist weathering well; nor does it require the periodic application of products to protect it from ultra-violet 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 additional sealant is needed, Alpha’s 1021 and/or 1010 sealant can be ordered nationwide at RV Dealers or online by visiting www.alphallc.us. Please note: only Alpha brand sealants can come in contact with Alpha roof membrane.

TPO – No coatings are necessary, as TPO is not a rubber, it is a plastic. The coatings made for rubber roofs will not adhere well to the TPO roof and will peel off much sooner
than they would off a rubber roof. A TPO roof does not wear away and get thinner over time the way rubber roofs do, which is why a coating is not necessary.

Thank you. This is good to know.

Use of sealants other than Alpha on a TPO roof could void the warranty.

I use Dicor.

there are TPO "friendly" versions of Dicor, and those are acceptable for Alpha System roofs. Standard Dicor sealant is solvent based and not suitable for TPO roofs. Make sure you use the correct one!

After washing the roof of our first 2010? Cougar 28SGS fifth wheel with Dawn all I have used since is Wet & Forget. Once, maybe twice, a year.

I have had both of our RV's roofs done by RV Armor, which is a lifetime warranty and it's transferable when you sell. The nice thing is they come to you. No more mandated roof inspections to keep the manufacturer's warranty, which seems to be a nightmare for some to get any service after the sale.
