CRAZING (1 Viewer)

[JaveaSteve]

Was washing the roof today and noticed the roof Crazing as shown in photo. Motorhome is only two years old but located in Spain so gets a lot of Sun. Is this crazing normal? Can it, Does it need repairing? Will it lead to possible future problems, ie: Water ingress?
Ps: What looks like Bubbling is water droplets.

The crazing is the result of stress fractures in the GRP.
It’s not unusual and shows quite often as a ‘spiders web’ pattern rather than your parallel lines.
I had mine repaired under warranty which is a quick process.
In fact I had two areas on the roof and one on the rear panel that I didn’t notice and were picked up on an annual service. I’d not spotted them.
My van was two years old at the time.
You can argue that over a very long time they could allow the ingress of water/damp and will need to be fixed.
Once your Moho has ‘settled’ from manufacturing to being used normally you shouldn’t get any more in the future.
Is your roof designed to be stood on? Some aren’t which could cause an issue. (Not suggesting you have btw)

Thank you Brooster. I've sent photos to "Hobby" who advised me to consult dealer. I had already sent them to dealer (Belt and Braces) who replied they have sent them to Manufacturer "Hobby". Now in Lock down so no immediate resolution likely. Have never been on the roof, bought extra tall step ladders so as to be able to reach all parts from sides and back.

That's very peculiar. I've never seen stress cracking follow that pattern. It looks more like some sort of mechanical damage to me. I'd be interested in the outcome after the dealer has looked at it.
