Super job on my flat roof and rebedding of ridge tiles.  The quote was competitive and the work went ahead as scheduled with a punctual start each day.  I was particularly impressed with the friendly and patient way Nik and Tea answered all my questions and addressed my concerns and worries; they really seemed to appreciate that these jobs are expensive for the householder and that choices and decisions are sometimes difficult to make. They reply promptly to e mails and phone calls and seem to really value your custom. TNT came to me highly recommended by a work colleague after she had used this firm for a complete new roof and loft conversion and I recommend them most highly myself. Sally. (Crosspool, Sheffield)
