None of that shows up on a plan symbol legend — but it changes your fastener schedule, your waste factor, and whether the building department signs off on the rough.

Stuff Portsmouth gutter contractors ask before they sign up
Does this respect NH code, or do I have to re-cut every quantity?
Counts assume IRC R301.2 / IECC Zone 5–6 (frost depth 48–60 in., ice-shield 36 in. past wall, historic district overlays). NH doesn't license gutters 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 measuring eave and rake lengths?
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 historic work in Portsmouth, the typical correction is one or two assemblies — not redoing the whole thing.
What about nor'easters bring heavy snow and wind?
Slate traditional but expensive. Architectural shingles most common. Ice and water shield required. Cedar shakes historic but fire risk. Snow guards needed.
How much does a permit add to a gutters job around here?
Plan on $175–$4,000 in Portsmouth, 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.
