I've been thinking of coating the roof with EPDM Coatings Liquid Roof. My fiberglass roof is beginning to break down. When I sweep the roof I get a cloud of sparkling glass floating around for a few minutes. Figure a coat of liquid EPDM would add a level of protection and maybe slightly dampen the sound of rain on the roof.

Ceramic Roof Coating

You may want to check this out. I ran into this outfit at the Tampa RV show who is doing a roof treatment using a ceramic roof coating like they used on the space shuttle tiles. You may have noticed it on some school buses.

The place was:
RV Collision and Restoration
4510 Hwy 40 Exit 352
Ocala FL 34482
P 352-251-0759
RV Repair Ocala 352-547-1870 RV Sales, Consignments, RV Storage, Parts and Service

And I think the product they use can be found here:

Elastomeric Waterproofing Insulating Ceramic Roof Coatings, Sealers, Metallic Finishes and Clears

Personally I'd prefer a product that was specifically designed to bond to fiberglass with no priming required. None of the coatings above state that they are designed to cover over fiberglass. Not saying that they wont work, I'm just saying that I'd prefer a product that states it's usable over the material I'm planning to coat and ideally was designed for RV use.

EPDM Coatings has two products. Liquid Roof is for RVs while Liquid Rubber is for all other applications. When I contact EPDM Coatings about the difference they said that the two products are virtually the same but the Liquid Roof’s cost was higher to cover the warranty for RV usage. Many I’ve spoken with have used the Liquid Rubber with great results. EPDM over fiberglass should last for years. They even have a FAQ about how to bond it to Eternabond tape.

I still prefer a product that doesn't require a primer for it to bond to the roofing material. I also don't like products that require more then one application (primer + 2 coats roofing material = 3 coats according to thier application method). Cost wise it's not as attractive as it seems because of the cost of roof coating plus the primer. I also don't care for a product that limits the amount of ponding allowed. The EPDM rubber is designed to be used as a sealant for landscape pond bottoms. That says something about the sealing capability.

Like I said... It may be just fine to use Permakote and may last a lifetime as well. I just don't want to have to spend the money and work 3 times as hard to get the same results.

Surface Preperation

What ever you decide to do, the key is the preparation of the old fiberglass roof before painting. Here is a good, brief 6 step description:

How to Prepare Fiberglass to Paint | eHow.com

I'm sure the product you pick will have recommendations for surface preparation.

Good luck with the project and keep us posted.

I'am curious about your fiberglas roof breaking down. Before I bought my 1993 33' LY it was always stored outside. The roof looked pretty bad, almost black in color. I power washed it, and I could see some sparkle of what I believe was fiberglas fiber,but everything was solid. The owner manual recommends periodic waxing. that what I've been doing and the roof looks great. I thought I read somewhere about these roofs not needing a full coating of any type, or that it wasn't recommended to do so. Here is a picture of my roof.

Looking good. You are fortunate to have inside storage for that baby. It saves a lot on maintenance.

Roof Coating

I use the white "Elastomeric" rubberized coating. I bought a 5 gallon bucket and I've done our 35' Land Yacht twice and our 20' enclosed car trailer twice also in the last 8 years. Still have enough to do them again.
First time the Land Yacht took about 1.1 gallons and less the second time.
Great stuff!! It's bright white reflects the summer sun and made a noticeable difference in the heat from summer sun. So far, the original taped edges have stayed in good shape. (But we keep it inside when not in use)

Paul, did you just clean your roof with TSP and then apply directly on fiberglas?
I used the Elastomeric also but just seams, vents, skylights etc. Seems to be holding up well, I just bought a gallon tape off and double coat every couple years. Never thought how doing the whole roof would help with reflecting heat better, I guess because it being white already.

What brand of coating did you use?

I've found that not all "Elastometic" products are the same and only one is a true liquid EPDM rubber. Home Depot sells one made by Gardner called Sta-Kool for $73 for a 4.75 Gallon bucket. The one thing I'm concerned about is, will it work on a fiberglass roof and for how long. I know that the Liquid Rubber EPDM coating is designed to work on fiberglass, but I almost never see anyone else advertise that it will work on fiberglass as well.

Any input would be greatly appreciated since I'm planning to do a roof coat in the spring. The liquid rubber would cost around $300 for 5 gallons while the Home Depot product would only cost $73 so it's hard to believe that they're anywhere close to the same. I really don't want to have to reapply it every couple years or so.

Roof Coatings

Agreed, not all Elastomeric coatings are equal. While not an expert on anything, I can tell you I've been happy with this one. LANCO
See:http://www.lancopaints.com/english/products/4.3_elas_latex_roof_coating.html
I re-coated mine because it was not white enough after several years and I always heard an ounce of prevention with Jack Daniel was a good idea.
(Or something like that) I'm a believer in the idea of reflecting the sun's heat does more for keeping cool in the summer than a bigger A/C.
I hope my 5 gallon bucket did not freeze and loose its adhesion or the past 4 years.
I don't remember the cost, but I know it was not $300 and could have come from a big box store.
