When the work is done we clear up properly — all waste removed, the site left tidy, a magnet run over the ground for stray nails where we have stripped a roof. We walk the job with you (or send photos if you are not there), and only then is the balance due. You receive your 10-year workmanship guarantee in writing, plus any manufacturer warranties on the materials, and it is transferable if you sell the house. If anything ever needs attention under the guarantee, one call brings us back — no quibbling, no re-charge.
A worked local example: a recent strip-and-relay on a 1930s semi in West Shore ran five days — day one scaffold and strip, days two to four re-felt, re-batten and re-lay the reclaimed slate with new stainless fixings, day five ridge, chimney lead and cleanup. The owner had a written quote up front, saw photos each evening, and paid the balance only on sign-off.
