Roof condition before you sign

Before putting solar panels on a roof, establish whether the roof and its supporting structure are suitable for the proposed installation. A cheap solar quote can become expensive if later roof work requires removing and reinstalling the array. There is no universal roof-age cutoff that substitutes for an inspection.

Separate the roof assessment from the solar sales proposal

Ask for a written assessment of roof condition, material, existing leaks, previous repairs and remaining serviceability. If condition is uncertain, obtain an independent roofing opinion. Structural capacity and local code requirements should be assessed by appropriately qualified professionals; photographs and a satellite estimate cannot establish that every attachment point is sound.

Request a layout showing the proposed array area and any required access paths or setbacks. Ask how mounting, flashing and cable routes interact with the roofing system. Get responsibility for leaks and damage in writing, including the labor needed to reach a covered defect beneath the array. Do not assume a panel equipment warranty covers the roof.

Compare the cost of coordinating work now and later

Ask for two itemized scenarios if reroofing may be needed: roof work before solar, and solar now with a documented future removal-and-reinstallation allowance. The latter should specify who performs the work, whether storage or transport is included, and what happens if the original installer is no longer available.

Use written quotes rather than a national removal-cost estimate. Roof shape, access, attachments, electrical work and local requirements can change the scope. Include the possible interruption of generation, inspection requirements and warranty effects. A bundled price is not enough detail to compare the alternatives.

Roof replacement is not automatically a solar tax expense

The IRS Residential Clean Energy Credit guidance says traditional components that primarily serve a roofing or structural function generally do not qualify. Its examples exclude traditional shingles and roof trusses while distinguishing solar roofing products that generate electricity. Installing panels does not automatically turn a conventional reroof into an eligible solar expense.

The same IRS page states that the residential credit is unavailable for property placed in service after December 31, 2025. Do not accept a blanket promise that a new 2026 solar-and-roof package receives a 30% federal residential credit. Earlier qualifying projects and special products require their own eligibility assessment; keep the roofing and electrical line items separate for review.

Before you sign

• Obtain the roof-condition report and proposed array layout before making an irreversible commitment.
• Confirm who is responsible for permits, inspections, structural work and coordination between contractors.
• Read roof, workmanship and equipment warranties separately, including exclusions and transfer conditions.
• Ask for removal and reinstallation terms, a contact for leaks, and a process for disputes.
• Check your insurer's requirements and discuss the proposed work before assuming existing coverage is sufficient.

Keep financing pressure out of the roof decision

The CFPB solar financing report explains how sales, installation and financing can be combined in one transaction and highlights hidden markups and misleading benefit claims. It is not a roof-engineering standard. Use it as a reason to obtain separate scopes and time to review the contract, not as evidence that a particular roof is safe.

If the roof cannot be made suitable on acceptable terms, compare other options rather than forcing the design. A ground-mounted system has different site and permitting needs; community solar depends on program availability and subscription terms. The right next step can be roof repair or a smaller project rather than signing immediately.

Take the buyer checklist to both contractors and compare the solar cash scope only after separating roof costs. These are procurement questions, not instructions for doing structural or electrical work yourself.
