Poor tiling around Velux?

[IvanTheTerrible]

Hi,

Would appreciate opinion in this tiling around a Velux. Builder says it is normal "in his experience". I think it is likely to result in rain getting under the tiles, or the tiles being lifter in strong winds. There is what looks like pieces of black foam sticking out from the edges of then tiles over the flashing around the Velux.

Thanks,
Ivan.

What's the pitch of the roof?

Thanks for those links. So it doesn't sound uncommon for it to look like that then.

I do still wonder about the foam though, as to whether it should be over the upstand on the edge of the flashing or not. It isn't like a continuous strip of foam but more like uneven bits sticking out from the edge of the tiles over the top of the upstand.

Rubbish why employ a builder to do roofers job.

 

[IvanTheTerrible]

It probably wasn't clear from my first post but the whole extension is new. When I challenged the builder, he did say he would talk to the roofer, so I guess he did use a roofer. But he still says that is just the way they are

Velux windows are made for pitched roofs so it probably looks worse than it is on that flat roof.

 

[IvanTheTerrible]

It isn't flat! Reckon it's probably 30deg.

Frankly if this were on your main roof you wouldn't see it and wouldn't give it a second thought, it is only that you happen to be able to see it from the worst possible angle.

 

[IvanTheTerrible]

Yeah, you're probably right. I guess I'll find out next time we have really bad weather.

More like 20 Degree!! No was is that 30 Degree..

 

[IvanTheTerrible]

Maybe, maybe. It's actually my mother-in-law's house, 100 miles away so I can't check!

What will you find out? That some rain gets under the tiles and then runs back down the underlay into the gutter?

should there not be a doubled up row of tiles at the bottom? (not an roofer)

Christ on a bike I read some blarney on this thread!

There is no way you can possibly get tiles to sit perfectly flat when installing a Velux, even more so when the tiles themselves are non profiled.

You can make efforts to reduce the kick but rest assured - there will be some kick. The foam, the lead corrugated bottom apron and the side flashings are all contribute to the problem.

Wind will not blow the rain in unless the idiot installer has messed up the foam trimming and has somehow flattened the the raised lip on the side flashings.

And whoever commented that this is a FLAT roof! Honestly!
