Roofing expert neded in bridgwater area

[selectcase]

Hi I was wandering if anyone could recommend a competent roofing expert in the bridgwater/somerset area as I have a chimney that needs the flashing repaired and re-pointed and the wet timberwork checked or are there any trade acociations i need to look out for when looking for one? - I appriciate that to re-do the chimney will require scaffolding and will probobly be costly.

basically the problem is a leak around the chimney that has gone unnoticed for some time - no leaks in the house but the chimney brest is damp and some of the small battons of wood around it are very wet.

thanks

will
