Solar Roof Project Assessment Checklist

• New build, full replacement, or an existing roof you're keeping?
• Drawings or roof plans, if you have them. Photos from the ground if you don't.
• Roughly how big the roof is and how many separate planes it has
• Which way the main planes face
• Roof pitch, if known
• What's on the roof now, and how old it is
• Dormers, skylights, chimneys, vents and anything else that breaks up the surface

• The project address, or at least the city and state or province
• Trees or buildings that shade the roof, and at what time of day
• Snow, high wind or coastal exposure that the roof has to deal with
• Any homeowners' association, historic district or design review rules
• Access for delivery and for working on the roof

• A photo of the main electrical panel with the door open
• Your utility company
• Recent electricity bills, if you want the system sized against your usage
• Whether you're interested in a battery or an EV charger now or later

This is the part people skip, and it's the part that shapes the design most. Write down what matters to you. It might be how the roof looks, how much of your electricity you'd like to generate, a budget you need to stay inside, or a requirement from a lender or planning authority. If two of those pull in different directions, say which one wins.

• When the roof has to be on, or when the old one has to come off
• Where the project is now: idea, design, permit, under construction
• Who else is involved: architect, builder, roofer, electrician
• Who makes the final decision

We look at whether the roof suits an integrated system at all, and tell you if it doesn't. If it does, the next step is a preliminary layout and a conversation about scope. Nothing on this list commits you to anything.
