I had this company for the few roofing jobs and repairing the guttering. Apart from covering the chimney they did not do anything what was they were contracted for. As it was roofing jobs I could not check it. All the problems remains the same. also has to pay someone to fix the guttering as it was leaking badly. I would not recommend this company for any job. They are not trustworthy.

Ali only shows to deliver materials or check work. Quick to reply when wanting the job. Slow/no response once job starts thinking you wont cancel.
