Hi again

Should eaves trays be overlapped?

my builder is saying they should be butted up but i have found evidence supporting my theory that they need overlapping. Can you helpful people shed some light for me

Overlapped

 

[landyandy]

Just fitted some to my extension and I overlapped by 100mm.

Best advice is to follow the manufacturers instructions.
I have seen instructions which say overlap and others say butt up.

As I see it, partly why they are used is to keep the underlay out of the gutter, so if they were butted then there is potential for water to drip through the edges.

We overlap ours 6 inches.

I overlap by a hand or half a span.
But my left-hand span is greater than my right-hand span, whereas my left-hand hand is less than my right-hand hand.

ha ha brilliant, Jeremy Beadle lol

Thanks for clearing this issue up. I will tell the builder and the roofer they have installed hundreds of eaves trays incorrectly around the county which will please them no end

Sometimes overlapping the tray can kick a tile or lath up.

If so, I prefer to have the trays butted together , but with some thin DPC underneath the joint, and some suitable tape over it
