I have had several estimates at around £1,600to mend mine and my neighbours gargage rooves - the two garages are joined and separate from our house.
I have been considering Polyskin as they say this will outlast felt but I am very unsure - a lady pensioner -can you advise me?
When you say 'MEND' Is it for patch repair or complete covering ? Can't really comment on price without seeing content of estimate. Type in the estimate content as an answer to your question and it can be reasonably judged.
