Most homeowners in the Roanoke Valley pay between $1,800 and $4,500 for a panel upgrade from 100-amp to 200-amp service. That range is wide because the job itself varies a lot from house to house. Here is what moves the number, and how to tell whether you need the upgrade at all.
What's included in a panel upgrade
A real panel upgrade replaces the panel itself, the breakers, and usually the service entrance equipment: the meter base, the mast, and the grounding system. The job includes a permit from the city or county, coordination with Appalachian Power to disconnect and reconnect service, and a final inspection. If a quote skips the permit, that quote is the problem, even if it's cheaper.
What drives the price
Three things account for most of the spread in that $1,800 to $4,500 range.
The condition of the service entrance comes first. If the meter base and mast are in good shape and rated for 200 amps, you save money. If they need replacement, which is common on homes built before the 1980s in neighborhoods like Raleigh Court, Grandin, and older parts of Salem and Vinton, that adds material and labor.
Second is grounding. Modern code requires ground rods and bonding that many older homes never had. Bringing the grounding system up to code is part of any permitted upgrade.
Third is what we find behind the panel. Double-tapped breakers, undersized wire, and aluminum branch circuits all add work. None of these are reasons to delay; they are reasons the upgrade was overdue.
Do you actually need 200 amps?
Sometimes no. A 100-amp panel in good condition can serve a small home with gas heat and gas appliances just fine. You likely do need the upgrade if any of the following apply:
You're adding a major electric load: a heat pump, an EV charger, a hot tub, a workshop, or an electric range where there was gas. You have a Federal Pacific, Zinsco, or fuse-style panel, all of which have documented failure problems regardless of capacity. Your breakers trip regularly under normal use. Or you're planning an addition or a full renovation, where the inspector will require adequate service anyway.
If you're unsure, ask for a load calculation. It's basic math any licensed electrician can do, and it gives you a yes or no answer instead of a sales pitch.
How long the job takes
A straightforward swap takes one day. Power is off for most of it, so plan around that. Jobs that include a new meter base or mast can stretch to two days because of the utility coordination. We schedule the Appalachian Power disconnect in advance so the downtime stays as short as possible.
Why permits matter here
Roanoke City, Roanoke County, Salem, and Botetourt County all require permits for panel work, and the inspection that follows protects you twice. It verifies the work, and it creates a record. When you sell the house, the buyer's inspector will look for that record. Unpermitted panel work is one of the most common reasons home sales stall in this market.
Getting a real number for your house
Photos of your current panel (door open), the meter outside, and a note about what you're planning to add are enough for us to give you a tight estimate, often without a site visit. Send us the details or call (540) 597-4964 and we'll give you a flat-rate quote before any work starts.
