01 — The Problem
Solar on the Roof — But the Roof Needs Replacing
This Old Bridge homeowner had a 22-panel SunPower system installed six years ago. The panels themselves were in excellent condition — SunPower panels carry a 25-year power production warranty and typically outlast the roofs they're mounted on. The roof, however, did not.
At 18 years old, the original shingles were curling, granule loss was significant across the south-facing slopes (directly under the panel field), and there were multiple soft spots in the decking we could feel during inspection. The homeowner knew the roof had to go — but they'd been told by other contractors that they'd need to hire a separate solar company to remove and reinstall the panels, then coordinate the two projects.
"Every roofer we called said they couldn't touch the panels. We were looking at coordinating two companies, two contracts, two sets of insurance, and hoping the scheduling would line up. Then someone told us Best Crew handles the whole thing."
The multi-contractor solar R&R problem is one of the most common friction points we see. When a roofing company and a solar company handle the same job separately, you end up with gaps in liability, scheduling conflicts, and no single party accountable if something goes wrong after reinstallation.
02 — Our Assessment
Roof at End of Life, Panels in Perfect Condition
We walked the roof and documented the full condition — both the roofing system and the solar array.
Shingles at end of life: 18-year-old 3-tab shingles, curling at edges, heavy granule loss particularly under and around the panel field (accelerated by heat retention from panels).
Soft decking in two areas: Moisture infiltration under shingles — likely around flashing boots. Two sections of OSB confirmed soft, requiring replacement before new roof installation.
SunPower panels in good condition: 22 × 400W panels inspected — no visible cracking, frame damage, or cell degradation. System was still producing at 94% of rated output per monitoring data.
Rail mounting system assessed: Rails and clamps in good condition — original hardware could be reused for reinstallation after new roof. Penetration boots and lag bolts replaced as part of R&R scope.
Electrical connections documented: String configuration, combiner box location, and conduit routing mapped before teardown — ensures exact reconstruction without guesswork.
Our recommendation: full roof replacement with all existing panels removed, documented, and stacked safely on the lawn. Replace any damaged decking during tearoff. Reinstall panels on Day 2 using the original rail hardware with new penetration boots and sealant.
03 — The Solution
One Company. Full Accountability.
The reason to use one company for solar R&R isn't just convenience — it's about who is responsible when something goes wrong. If two contractors work on the same project and a roof leak appears near a penetration point six months later, both companies point at each other. With a single contractor handling everything, that argument doesn't exist.
Why One Contractor Matters
🔒
No liability gap: Every penetration point — lag bolts, conduit runs, junction boxes — is our work. The roof warranty and the reinstallation workmanship warranty are both under one contract.
📅
No scheduling mismatch: Panel removal and roof install happen in a continuous sequence. No waiting for a second company's availability. No panels sitting on the lawn for an extra week.
⚡
Faster back online: System producing within 48 hours. Multi-contractor projects typically take 5–10 days to coordinate from roof complete to system test.
💰
Lower total cost: Single-contractor overhead vs. two separate project margins, mobilizations, and profit structures.
GAF Timberline HDZ Weatherwood: Architectural (dimensional) shingle, 130 mph wind rating, 30-year limited warranty. Weatherwood color chosen by homeowner — warmer tone than Charcoal, complements the dark solar panels.
Soft decking replaced: Two areas of compromised OSB removed and replaced during tearoff — no surprises after the fact.
New penetration boots at every mount: All 22 panel attachment points get new EPDM flashing boots and sealant — new roof, new seals, full protection.
Original rail hardware reused: SunPower rails and clamps were in good condition — reusing eliminates cost while maintaining manufacturer spec.
Electrical reconnection and system test: All connections reinstalled and tested by our licensed electrician. Monitoring app confirmed system at full production before we left the property.
04 — The Numbers
$18,400 vs. $23,000+
The homeowner received quotes for the two-contractor approach before calling us. Here's how the numbers compared:
Two-Contractor Approach
$23,000+
Separate roofer + separate solar company. Two mobilizations, two project margins, scheduling coordination required. Typical 5–10 days between roof complete and system back online.
Best Crew — Single Contract
$18,400
Everything in one contract. Panels removed Day 1, roof complete Day 1, panels reinstalled Day 2. System online within 48 hours of project start.
$4,600 Saved
vs. two separate contracts — plus faster completion, single warranty, and no coordination overhead
The savings come from consolidated overhead and a single project mobilization. The two-contractor model has each company adding their margin, insurance, administrative overhead, and mobilization costs independently. A single contractor does it once.
05 — The Process
Day 1 + Day 2 — Complete
Two-day project. Day 1 was the demolition and new roof. Day 2 was panel reinstallation and system test. Here's exactly how it ran.
Panel Removal + Safe Stacking
Six-man crew on site. All 22 SunPower panels disconnected at the string level — DC isolated, AC disconnect opened. Panels removed in sequence, labeled by location, stacked on foam padding on the lawn away from the work zone. Rails and clamps removed, catalogued, and staged for reuse. Conduit runs left intact and capped.
Full Tearoff
Existing shingles and underlayment stripped to deck. All old penetration boots and lag bolts removed — every mounting point back to bare OSB. Deck inspected across entire field.
Soft Decking Replaced
Two areas of compromised OSB identified and removed — both in the zone around former penetration points that had been leaking. New 7/16" OSB installed, nailed to rafters. Homeowner notified and shown the damage before repair.
Underlayment + New Roof Installation
Ice & water shield at eaves and valleys. Drip edge installed. Synthetic underlayment over full field. GAF Timberline HDZ Weatherwood installed from eave to ridge. Ridge vent and ridge cap completed. Roof fully watertight by end of Day 1.
Day 1 Complete — Roof Done, Panels Staged
New roof fully installed. Panels remain safely stacked on the lawn overnight. Crew off property. Homeowner updated — full walkthrough of day 1 work before departure.
Rail Remounting + New Penetration Boots
Lag bolts reinstalled into rafter bays at original layout positions — new stainless hardware. EPDM flashing boots installed at every penetration point and sealed with Geocel ProFlex. Rails remounted and leveled per original configuration. All 44 penetration points sealed before shingles were disturbed around them.
Panel Reinstallation
All 22 panels reinstalled on rails in original layout, clamps torqued to spec. MC4 connectors checked for condition before reconnection. String connections made at combiner box. Conduit re-secured.
Electrical Reconnection + System Test
DC circuit verified, AC breaker closed, inverter powered on. System began producing immediately. Monitoring app checked — all 22 panels reporting. Production at full rated output. System test complete: 8,800W total capacity confirmed online.
Cleanup + Final Walkthrough
Dumpster loaded. Foam padding removed from lawn. Magnetic roller run across full property. Gutters blown clear. Homeowner shown monitoring app confirming production. Job complete and closed.
06 — The Result
New Roof. System Online. $4,600 Saved.
The SunPower system was back at full production within 48 hours of project start. The homeowner avoided the coordination overhead of two separate contractors and saved over $4,600 compared to the quotes they received for the split approach.
Every penetration point has new EPDM boots and sealant under new shingles — the most common source of leaks in solar-on-roof systems is compromised flashing around mount points. That risk is eliminated on this install.
We were dreading this. Managing two contractors, trying to get the schedules to line up, not knowing who was responsible for what. Best Crew showed up Monday, and by Tuesday afternoon the roof was done and the solar was back on. I checked the app — everything working. Can't believe it was that smooth.
