New Flat Roof Pooling Water -

Jwc3051

Hi Everyone -

I hope I can get some advise regarding a flat roof on a new rear extension -
I had plans drawn up for a new extension the build went a head and I have to say the work is great and they finished on time and with in budget - and does look amazing I have to say - BUT when is rains I get a lot of pooled water on the roof on the left and right of the roof, now I understand its called a Flat Roof but I would of thought as a new build should it not be taken it to consideration to make sure there is enough of a tilt for all the water to run off ?
I have spoken to the builders and they are coming round to look at this as I sent them pictures  and as we all know its can rain a bit in Ireland.
in the reply email this is what they said about pooling water
[font=Calibri","sans-serif]the water after rain lodges on the roof which is reasonable and  accepted within industry as it is a flat roof with some minimum  pitch –in any way it doesn’t compromise the structure of the roof at all  and additionally you have the guarantee[/font][font=Calibri","sans-serif]-[/font]

[font=Calibri","sans-serif]Cheers[/font]

[font=Calibri","sans-serif]My question is there rely correct ? and is this a mistake that they should rectify.[/font]

A joint warranty between builder and manufacturer?
For how long?
What pitch did the manufacturer product instructions call up for the warranty?
Was there a Drawing & spec - did they spec a certain pitch? Maybe crickets?

Hi Bryan

I had full architect plans (which were not cheap) which to be honest i don't fully understand,
i know the build has a 10 year guarantee -

i am a total novice at building, so this is why i got a very well know Architect company for the plans and a building company with a good reputation for new builds. when i look at the pain i can't tell if a tilt is supposed to be there or not. but the pooling is bad i have taken photos of this any emailed the building company and as you see the reply is its normal -

i will email the architects to see what they have to say as well.

What finish is on the roof?

Fibreglass roof

In the middle of a renovation/extension at the moment. Our
contract with the builder stipulates that he doesn't get the final 5% of his fee until 6 months after the build is finished - provided he puts all snags right. I presume you don't have something similar in place?

did the arch sign off the build / roof?

The Sang list was done and we are very pleased with the build apart from the Roof - it did not rain at first so we never noticed it

the company have agreed to come round to investigate and i have spoken to the architect as he is also going to look over the work again and check it all out - im quite optimistic this will be rectified as all parts have agreed to investigate this issues -

Hi there, I'm just wondering was all ok with your build regarding the rain water, were having the same issue, but our builder said it's normal and that all is ok, the rain water is resting on the edge of our parapet. Kind regards Diane

Our friend was the architect we had an engineer but it was a simple 16 by 20 extension with flat roof n sky light so we didn't go with the expensive of drawing, there was 6 site visits n all went well, our friend the architect n engineer said a little rain water is normal but is it 🀔?
