Is it acceptable for a rubber roof to have ripples?

[jamphi24]

Hi
Had a new rubber roof fitted and the builders that did it have left it as per the attached picture. Is this acceptable or should I be asking for them to redo it? I presume if so they would need to lift it and re glue?
It looks pretty bad obviously and seems to be effecting drainage. I presume in time could cause other issues or am I over reacting?

That is **** poor!

No over reaction on your part, this is bad

 

[scruffybiker]

Here is an example of how bad it is... me and my partner some our flat roof. With rubber. Never done it before etc no ripples...

Take issue with the builders/installers and go for a refund - dont allow them to have another go.
Get a specialist roofer, who claims to specialise in this kind of work, to re-do the job.

In time its possible that that rubber will curl up, and pull away from its deck.
Make sure that the new roof has enough falls, and discharges over & into the gutter at the fascia.

FWIW: the flat roof next door seems to be ponding - was it done by the same people who did yours?

ditto to that ^^^^
The most likely event is that eventually most of that will come unstuck from the roof.
I agree with scruffybiker a talented amateur should get a better finish than that.

Speaking as a talented amateur, I did my first ever EPDM flat roof last year (20 sq m, irregular shape), it had no ripples then and it has no ripples now. EPDM is heavy stuff, it wants to lie flat, and doesn't need much encouragement with a broom to do so. Possibly the deck wasn't dry, and that has limited adhesion. I'd be concerned about the apparent poor adhesion at the edge.

If it was raspberry ice cream, then yes. On a roof, no.

Is it a new build? or a re-roof job, I suspect the latter and it isn't even glued down at all, and just going by how bad that looks is it possible the old roof is still under there!

 

[jamphi24]

'Next door' is actually still my property is just a new build extension on an existing extension.
The bit closet on the photo is a re-roof and the far bit is the new build.
Thanks all for the comments. I have contacted the builder to see what he proposes.

just to say the new build roof seems to have the same problem, ripples and pooling at the eaves end of the roof.

They just probably glued the wood and not the rubber also and laid it too quick. That's quite bad.

But nothing will beat this world record.

If it's water based then you only need to glue the wood.

Nope! Both the rubber and the wood must be glued together. I'd dig out the Firestone factsheets but it's past my bedtime.
