Stuff Wilmington flat roof contractors ask before they sign up
Does this respect DE code, or do I have to re-cut every quantity?
DE doesn't license flat roofing at the state level, so the variability comes from local amendments. Quantities are correct; you adjust crew rates and local permit assumptions in the bid summary.
How do you handle low-slope drainage calculations?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For financial work in Wilmington, the typical correction is one or two assemblies — not redoing the whole thing.
What about site conditions?
Build the local condition into your assembly defaults once, and it carries forward to every Wilmington bid afterward.
How much does a permit add to a flat roofing job around here?
Plan on $175–$4,000 in Wilmington, with review running 3–5 weeks. Build that into general conditions so a slow plan-check doesn't eat your overhead. Insurance and bond are separate carrying costs.
