The decision that costs more on every quote.
Ridgeback could work off ladders on smaller jobs, the way plenty of roofers do, and undercut its own quotes by leaving the scaffold out. Twenty-two years ago the firm decided not to, on the grounds that a ladder is how roofers get hurt and it puts the work itself at an awkward angle that shows in the finish.
The scaffold is priced separately on every quote so the cost of that decision is never hidden in the total. Two crews, both directly employed, work to the same rule whether it is a single chimney repair or a full re-roof.
