Roof coatings.

[ken56]

Anyone familiar with RV Armor, Flex Armor Gaco or other liquid roof coating? I suffered some damage to my roof and am being told I need a whole new roof. It's only 4 years old but I understand a dealer service shop needs to cover their butts if they are going to guarantee a new repair installation. Is the liquid roof stuff a good option? It's almost half the cost of a new TPO or EDPM membrane. Any insight here?

I went with the RV Armor. Waiting to schedule the work and cooperative weather.

Out here in AZ we use a rubberized roof coating on our homes. Some people have been using this coating on their RVs with success. I've only used it on my home and am very pleased with the results. It paints on with a roller and drys quickly.

Are you talking about a silicone based coating? I'm hearing many in AZ are using that on flat house roofs over the elastomeric (foam roof) coating. Have also been considering the silicone coating (from Home Depot) over my 15 year old trailer TPO vinyl roof (which is actually still in real good shape!).

Just wanted to suggest: Gotta make sure you got the right coating for the right roof base material. When applying Eternabond, I always round any corners. I believe it helps resist peeling up. Also if there is a forward facing edge of the Eternabond, sometimes I coat that forward facing edge with a urethane caulk. My roof is fiberglass but I covered the front and rear cap seams with Eternabond. .

Small rips from the limbs

Clean the surface with correct solvent
Cover rips with Eternabond tape
You can seal over that with a roof coating (if you want to) but it is not needed

If it was mine, I would use Eternabond to repair those tears, then consider coating it with something. Four years doesn't seem that old to me. Maybe it's because I'm up north. I used Hengs on my then 14 year old rubber roof and am happy so far after 2 years. I repaired it several times over the years with Eternabond due to tree limbs. Worked perfectly.

I used liquid EPDM the first time and it lasted about 5 years. This last year I applied Tropicool. Made by Henry’s I think. Available at Home Depot.

I did repair a tree tear prior to the coating. No leaks.

My roof is 19 years old now so the next coating will be a new roof.

Tangled with a tree branch and only small minor scraps and tears in the TPO, roof decking is still sound and no rot. So far the consensus is it's a good coating.

No one can make a proper long term fix recommendation without first seeing how much damage was done.
Some are making recommendations of what they did with no roof damage. They simply had a coating job done.

If I had a older unit and was repairing a torn roof then a quick patch job and then a quality coating may gain a few more years.

If the unit is newer and I was going to keep it for several more years I would replace the membrane.

My only suggestion is before buying a product from a recommended manufacture, make sure it's appropriate for your type of roof. Some manufactures make multiple products under their roof coatings each designed for a particular type of roof. If you buy based on the brand name because it's labeled for RV roof repairs, you may be disappointed when it doesn't work properly on your roof material. Make sure you are matching product specs to roof material being repaired and not just cause a name was thrown around.

Oops. Tried to do a quote, but went without my comments.

I justy had the same spray on done to my 5th wheel & it is awesome. Very tough and durable, and eliminates the caulk maintenence around the seams and protrusions. It is a one piece seamless product once finished.

This is what I put on my 5th wheel. IMHO nothing better.

Got a bit of a rub on the corner of mine. No biggie. Taped it for good measure & plan on using the Heng's, 2 coats min, after a good prep job on the original surface which has been stored indoors for most of its 12 year life & had regular cleaning & maintenance product applied.

New EPDM: $9000, 1 year warranty.

Rhino Coating: $6500, 10 year warranty.

I'm very happy with my Rhino coating job, and even happier that it was paid for by my auto insurance policy!
