Roof age alone does not decide whether replacement is necessary. Material, installation quality, leaks, repairs, storm history, deck condition, flashing, ventilation, drainage, and remaining service life all matter. Begin with documentation and a physical evaluation rather than an online age estimate.
Inspect the roof before placing panels
Ask a qualified roofer or appropriate professional to check shingles or other roofing material, decking, rafters or trusses when relevant, flashing, penetrations, drainage, soft areas, and visible repairs. The U.S. Department of Energy’s consumer solar installation guide recommends confirming that the roof can support solar and notes that coordinating solar with a roof replacement can sometimes avoid later work.
A solar installer should also explain attachment locations, setbacks, pathways, equipment weight, and how the design responds to the roof structure. Review severe-weather details in the Lee’s Summit hail and solar guide.
Compare remaining roof life with the solar plan
If the roof is near replacement, installing panels first can create another project later: electrical shutdown, panel removal, protected storage, roof work, reinstallation, testing, and possible permit or utility coordination. Request written estimates for that future sequence before deciding to postpone the roof.
If the roof is sound, replacement may be unnecessary. Ask the roofer to document condition and repairs, then have the solar designer confirm how mounting and waterproofing will be handled. Avoid broad guarantees that are not supported by written workmanship and product warranties.
Coordinate the roofer and solar installer
DOE’s current solar-installer selection guidance recommends asking whether roof repairs are needed, who is responsible for roof damage or leaks, and how vents affect panel placement. Put responsibilities in writing: removal of old roofing, deck repairs, flashing, attachment layout, penetrations, leak response, warranties, and final inspection.
Plan vents, shade, and usable roof area together
Roof replacement can be the right time to discuss vent locations, but changes must be evaluated by the appropriate roofing and mechanical professionals. Do not move a required vent simply to fit another panel. Ask for two layouts when useful—one with the existing roof geometry and another showing any properly approved changes—then compare cost and expected production.
Confirm both roofing and solar permits
The City of Lee’s Summit’s current miscellaneous-permit page states that permits are required for re-roofing and for all solar-panel installations. Ask who submits each application, what drawings are required, how inspections are sequenced, and whether changes to the electrical service create additional work.
Compare complete project costs
Request separate line items for roof work, solar equipment, attachments, electrical work, permits, potential structural work, and any future panel removal and reinstallation. A low solar payment should not hide a roof expense that becomes unavoidable soon after installation.
