Joining new slates with old

[mreinor]

I have a small lean to roof which I'm removing the existing corrugated covering from. Next door it's slates which extend about a foot under the covering, so I assume that someone just added the corrugated covering at some point for whatever reason.

 

When I put the new slates on, how should these be tied in with the neighbouring slates? Will it need a jointing gutter, or can I just continue the existing slates into the new ones (which are the same 500x250 size). See pic attached

As you say a bonding gutter can be used.

Or speak to your neighbour and take a couple of rows of slate off their roof , felt abd batten it overlapping into the original roof and tie it all in properly.

Just be aware the corrugated sheets could possibly be asbestos.

A simple sample test will confirm this either way for about £30/35

Yes it is asbestos, I didn't mention it to avoid the thread careering off track Someone is coming in next week to remove it.

That's sorted then .

Personally I would try and blend it in with your neighbours,  a better job long term
