Bumpy roof on our MH (1 Viewer)

[Spidey]

Does this sound right to you, not sure if i am worrying about something and nothing :-(

OH was washing the roof today and noticed that the front part of the roof appears to be bumpy, quit big bumps. This is on the flat part of the roof. Also the masking stuff around the front of the roof appears to have black mould in it.

We have taken a photo so will try to upload it later. Should we be mentioning it to our dealers?

 

[Munchie]

Yes! Sounds like delamination!

What make is the van? Is it an aluminium or GRP roof?
GRP roofs are often not bonded so can move and ripple but should only be slight if they are large bubbles you may have a problem.

Its a chausson flash 510, o dear don't like the sound of delimitation
:-(

Our polyester roof on our Chausson has always been bumpy. It was like it new.
It's just a very flexible construction.

Don't worry about the black marks.
I think it's a fungal growth within the sealer.
It's normal and won't cause any problems.

Does that look normal?

Also while i am on a roll. Took e MH down to the garage and there was a lot of rattling from what seemed like inside the facia at the bottom of the roof window. Could bits get into that area?

Looks just like mine - no leaks from it.

I didn't think mould could grow on good quality sealant.. But it should still be doing its job.. I wonder if the dealer would "rake" it out and re-do it ??
Be reassured by the other folks with like vans who have the same 'ripples'...

 

[Judge Mental]

dont panic, some grp roofs are not bonded but float as they expand and retract with the temperatures...stops them cracking. check with dealer to find out how its constructed

It is a Polyester 54 mm thick reinforced roof designed to move/flex in different conditions. While it might be unsightly, they have as much as I have researched, an excellent positive record on the lack of water ingress.

I would clean the black mold off.. if left it will continue to eat into the sealer and may eventual cause it to leak..

Use a soft brush and scrub with soap and mild bleach solution or buy a fungicidal cleaner..

For peace of mind I would have the roof checked by the dealer..

Just checked my one month old Chausson 718 and yep, the front section of the roof is rippled just like the photo above. Strange I hadn't noticed it before as the van is parked below my bedroom window and I see the roof every day, so I guess it must be temperature dependent?

I can see our roof from bedroom window, but never noticed it. Mind you it was a bit dirty as park near trees. Only when hubby cleaned the roof we noticed
