My kitchen extension currently has a flat felt roof which

now defective I would like to change it for a pitched, slated
roof. My neighbour however is unhappy about my builder having to
get onto his portion of the roof in order to complete my new
roof.

Next door to us had to have scaffolding put up,
and asked if the scaffold firm could put the odd
slanty prop on our land, for safety. That's ok,
I thought, no problem.

In fact the scaffolders took the permission as
an open-ended licence to use our land... parked
their bloody vehicles on our drive, took their
stuff in through our side gate, (knackering the
hinges on the way), littered our side of the
fence, you name it....... it seemed that they
disturbed us rather than their (paying) customer.

So I understand your neighbour's reluctance to
allow your builder access to his property. Why
should he? There is no benefit to your neighbour,
just aggro and possible (probable?) damage.

Your builder can do damage, shorten the life of
your neighbour's felt roof, and be off and away
before anything gets noticed.

Perhaps you should offer to replace his felt roof
anyway, as compensation for the inevitable damage.
