Ivy & wisteria removal from external brickwork and roof

Hi everyone,

Does anyone know of of any specialists who are qualified to remove ivy & wisteria from brickwork and roofs?

The ivy which stems from our neighbour's garden, has pretty much covered the back of their house, but has made it's way onto our house, and up and over the roof.  We're very worried it is damaging the brickwork, mortar and roof, and need to have it removed asap.

We need someone who has knowledge & experience in this, in order to minimise any damage caused to the brickwork, pointing and roof.  I appreciate some damage is going to be inevitable, but I'm concerned about someone who isn't experienced in this type of thing going in and 'ripping' (so to speak), the ivy from the house, which will cause more damage than careful considered removal.

I've attached a photo.  The window on the right is our bathroom window, and you will see our neighbour's house to the left is covered in ivy and wisteria.

Thank you.
