2004 U270 roof cracks

I just purchased this coach and upon inspecting the roof I found many hairline cracks and two impact stars. I have been trying to find the best solution and permanent fix. I have been looking at a company out of Florida called rv flex armor. I was wondering if anyone out there has any experience with them. Any help with any solutions would be appreciated.

Please post pictures.

From that we may be able to determine if this is structural or just superficial.

Also, if not in an area that is visible from the ground, you may be able to just use a piece of ETERNABOND to cover that area.

Said another way, certainly may not need a complete roof recoat.

This post could not come at a better time for me. Here are a few examples of what I am seeing on my roof. I am hoping to do something about this asap.

Are those the only areas, or is it more wide-spread?

We were very happy with the work Xtreme did on our 2002 270.  Same hairline cracks and there are a few areas (including where a no longer used satellite dish uncovered holes from prior installs.  All the old holes were repaired with fiberglass then they coated the whole roof with a white paint with an anti-slip additive.

Joe,

Do you know what "white paint" they used?

Those tiny cracks almost look like they are in an aftermarket roof paint job. I think I would clean and sand the roof well and then use a marine top side two part paint. Good selection and videos here: two part topside epoxy tip and boat at DuckDuckGo

The PO of our U300 used several coats of Dicor, the most evil substance ever invented by man. It cracks and water can travel underneath so hard to find exactly where the leak is coming from. It took me weeks of a heat gun, blood, sweat and anger to get if all off. I then worked with a friend to roll and tip the paint (see videos for rolling and tipping). I would not advise spraying the two part paint as the hardener is very toxic. Quote, "Spray polyurethanes are made with isocyanates and emit volatile organic compounds (VOCs), which makes them toxic. This toxicity is heightened when it is sprayed."

The paint went on easily and looks good today. I didn't add any sand or anything to give better traction as I felt that it could attract dirt easier and be harder to clean. I don't have a problem walking on it if it's dry.  The white was a pretty close match to the body and any difference cannot be seen from the ground.

Rance said they use an acrylic paint and add the anti-skid glass.  When researching, I saw this post with input from folks who had Xtreme do the work.  Roof Coating   

I would guess they are using the same or similar paint that Gary and Jeannie mentioned.

I think there are probably a million times more gallons of fiberglass paint used on boats compared to RVs. Reading reviews on the brands and application techniques used to apply it on boats are the best as the use on boats is more demanding compared to RVs.

I would say those are cracks caused by some water leaks on one or more roof penetrations. Water gets in and migrates between the gelcoat and the fiberglass or the fiberglass and the plywood. Any or all of the root penetrations are suspect. Roof vents, skylight, A/C units, satellite, antennae, etc. You will likely find screw holes with spider cracks emanating from the hole. The water can then travel many feet. Check for soft spots and that will mean that the fiberglass has separated from the plywood. It can be rebonded by injecting into holes or in a worst case taking up a section and replacing or rebonding and patching seams (I believe someone else has posted their project).

It is all fixable, it just takes some time. Or pay and get it done all at once. On our coach I have ground out the cracks and repaired the gelcoat and fiberglass, patched no longer used penetrations and resealed all fixtures and screws. I have not yet done the paint.
