Solar-Ready Roof Upsell Playbook: Partner With Solar Installers
Every solar installation sits on a roof. The roofer who gets there first, builds the roof correctly for future solar, and partners with solar installers turns a standard re-roof into a higher-margin, multi-revenue-stream relationship. The play is simple: position as the solar installer's preferred roofer, upsell solar-ready work on retail roofs, and collect referral fees on solar installations you introduce.
What Solar-Ready Actually Means
A solar-ready roof is a roof designed from day one to accept solar panels cleanly, safely, and without voiding warranties. Components of a true solar-ready spec:
- Reinforced decking: Minimum 5/8 inch plywood or OSB rated for point loads
- Pre-installed flashings: Quick-mount or similar attachment points installed under shingles
- Conduit run: Roughed-in conduit from roof to electrical panel, usually through attic
- Junction box: Pre-wired roof junction box for future microinverters or optimizers
- Structural documentation: Engineer letter or truss certification confirming the roof can carry added weight
- Unobstructed south and west slopes: Vents, skylights, and chimneys positioned to leave clean panel areas
Upsell Pricing
Typical solar-ready upgrade on a residential re-roof:

Attach rate to standard re-roof: 8 to 18 percent if offered actively. Higher in markets with strong solar adoption.
Partnering With Solar Installers
Solar installers have a problem: 20 to 35 percent of the homes they quote have a roof that needs to be replaced before solar. Either the homeowner does not realize it, or the solar company does not want to tell them, or they do not have a reliable roofer to recommend.
Become the roofer they trust. Benefits to you:
- Pre-qualified leads (homeowner is already sold on solar, needs a roof first)
- Higher close rates (urgency is real: solar project is on hold)
- Clean installs because the solar company confirms your work meets their standards
- Potential referral revenue when customers you refer to solar close
Reciprocal Referral Structure
Common structures:
- Cash referral: Solar company pays you $250 to $750 per roof they send your way. You pay them $200 to $500 per solar install you send their way.
- Revenue share: 2 to 5 percent of the roofing job back to the solar company that referred.
- Bundled proposal: You and the solar company present one proposal with the combined cost. Each takes your own margin.
Track referral economics: on average, every 100 solar customers you get referred results in 35 to 55 signed roofs at $14K average, or $500K to $775K in revenue. That is worth structured partnership investment.
Finding Solar Partners
Every market has a dozen or more solar installers. Identify top 5 by annual install volume. Research on Google, state solar registry data, or industry trade groups. Approach in this order:
- Mid-size regional installer: 300 to 1,500 installs per year. They have volume but still need partners. Easiest to reach.
- Large national installer: Sunrun, Sunnova, SunPower. Slower to onboard but bigger volume. Worth year 2.
- Small local installer: Under 300 installs. Close relationship possible, limited volume.
Standards Solar Installers Require
To be a preferred roofer for solar companies, you need:
- General liability $2M minimum, naming the solar installer as additional insured on jobs
- Workers comp and commercial auto
- Clean workmanship (photos, reviews, no open lawsuits)
- Ability to schedule jobs within 2 to 4 weeks of request
- Knowledge of panel attachment patterns (they will tell you where stanchions go)
- Willing to install roof with solar in mind (not just finish and leave)
The Retail Solar-Ready Pitch
When selling a retail re-roof, add this line to every presentation:
"Have you thought about solar for this home? Either now or in the next few years? If there is any chance, we can pre-install mounting flashings and conduit while the roof is off. The cost is about $3,500 and it saves you 3 to 5 times that when you go solar because the solar installer does not have to cut and re-seal your new roof."
Attach rate in solar-friendly markets: 12 to 22 percent. In markets with less solar interest: 3 to 8 percent. Either way, the extra revenue per attach is $3,500 to $7,500.

Installation Best Practices
Flashings
Install Quick-Mount PV or IronRidge flashings on 6 to 12 expected panel attachment points. The solar installer provides the grid layout ahead of the re-roof if the partnership is tight. Otherwise, install in a standard pattern that accommodates any future array up to 10 kW.
Conduit Roughed-In
Run 1 inch EMT or flex conduit from the roof (junction box location) through the attic to the main electrical panel. Pre-pull fish tape. Leave the conduit capped and labeled "FUTURE SOLAR." Total labor: 2 to 4 hours. Material cost: $75 to $200.
Panel Weight Consideration
A typical residential solar array is 5 to 10 kW, weighing 800 to 1,600 pounds distributed over 300 to 600 square feet (3 to 5 pounds per square foot). Modern trusses handle this fine but older homes or cut-stick framed roofs may need reinforcement. Recommend an engineer inspection on homes over 30 years old before warranting solar-ready.

Marketing the Partnership
Once you have a solar partner, market the joint offering:
- Landing page: "Roof + Solar Package"
- Shared booth at home shows
- Joint direct mail to neighborhoods with solar-friendly profiles
- Cross-referencing on company websites
- Joint case studies showing roof + solar installations
Customer acquisition cost per joint sale: 40 to 60 percent lower than solo. Close rates on joint leads: 30 to 45 percent vs 12 to 22 percent for solo roofing leads.

FAQ
Should I get into solar installation directly?
Probably not. Solar installation is a different license, different crew skills, different equipment, different financing. Unless you want to build a second full business, partner instead.
What if the solar company damages my new roof?
Pre-negotiate a workmanship arrangement. Your roof warranty stays intact if the solar installer uses your approved attachment flashings. Any damage outside those flashings is solar company responsibility. Document in writing.
How much solar-ready attach rate is realistic?
Without mentioning it, 0 percent. With a proactive pitch on every proposal, 8 to 22 percent in most markets. In solar-mature markets like California, Arizona, Colorado, New Jersey: 15 to 30 percent.
