How it works

Three steps to a total project number

Step 1

Enter your roof details

Size, material, and complexity together set your reroofing cost, the same inputs the roof replacement cost calculator uses.

Step 2

Enter your solar system size

This sets your solar cost using a typical per-watt installed rate for a standard residential system.

Step 3

Compare bundled versus separate totals

The report shows what you'd save by coordinating both projects together instead of scheduling them independently.

Why bundling actually saves real money

What a bundled project runs

A combined project with a 2,000 square foot architectural shingle reroof and an 8 kW solar system typically runs 33,000 to 34,000 dollars in the US when bundled, compared to roughly 35,800 dollars if done as two separate projects. That's a savings of 5 to 8% just from coordinating the work together. Run the same inputs through Tax credit and rebate estimator (California) to cross-check this figure.

Where the savings actually come from

Bundling avoids duplicate mobilization costs, since setting up staging, scaffolding, and safety equipment once instead of twice cuts real labor hours. Permit applications can also overlap when submitted together, and a single contractor coordinating both trades reduces the scheduling gaps and communication overhead that come with managing two separate projects and two separate crews. For the financing side of this decision, see Financing cost with ITC applied.

Why sequencing still matters even when bundled

The roof always goes on first, and the solar installation follows on the completed new roof, even within a coordinated bundled project. This sequence keeps warranty coverage clean at the boundary between roofing and solar work, which the roof vs panel warranty overlap tool covers if warranty coordination is a concern for your specific contractors. This matches the guidance in how to claim the residential clean energy tax credit.

What to check before committing to a bundled quote

Confirm whether your contractor bundles both trades directly or subcontracts one to a partner, since that affects accountability if something goes wrong at the roof-solar boundary. If financing is part of your plan, the combined roof and solar financing tool covers how lenders typically treat a bundled project versus two separate loans.

the homeowner's guide to going solar and how to claim the residential clean energy tax credit go further into the new-construction angle. Worth pairing with the Financing cost with ITC applied and the Tax credit and rebate estimator (California) for the financial picture.

Questions

Frequently asked

A combined project with a 2,000 square foot architectural shingle reroof and an 8 kW solar system typically runs 33,000 to 34,000 dollars in the US when bundled, compared to roughly 35,800 dollars if done as two separate projects.

Yes, typically 5 to 8% compared to doing both as separate projects, since bundling shares mobilization costs, overlapping permit work, and avoids paying twice for scaffolding or staging. The savings scale with project size, so larger combined projects save more in absolute dollars.

Some contractors handle both roofing and solar directly, while others partner with a specialist for one or the other. Either arrangement can work, but confirm who is responsible for flashing and warranty coverage where the two trades meet.

The roof always goes on first, followed by the solar installation on the completed new roof. Scheduling both with the same contractor or closely coordinated contractors keeps this sequence tight and avoids gaps where the roof sits exposed without its final protective layer.
