Solar + roof, one project
Solar and roof replacement, in the right order
Putting a 25-year solar system on a 10-year roof is the most expensive sequencing mistake in home energy. Done together — reroof first, solar right behind it — you skip the future $3,000–$5,000 panel remove/reinstall, align every warranty, and finance it as one project.
Here's the conversation nobody has until it's expensive: solar panels last 25+ years, most Southern California asphalt roofs last 20–30, and huge numbers of homes go solar on roofs already halfway through that life. Five or ten years later the roof is due — and now every panel has to come off ($3,000–$5,000, plus permits, plus weeks), get stored, and go back on a roof installed by a different contractor who'd rather not warranty someone else's penetrations. The fix costs nothing extra: check the roof first, and when it's near the end, replace it as part of the solar project. One assessment, one financed scope, one accountable company — our licensed roofing partners on the tear-off, the Helios crew right behind them.
Why the bundle wins.
Not marketing synergy — sequencing math.
No future remove/reinstall: the single biggest avoided cost, $3,000–$5,000 plus downtime
Warranty alignment: roof material (30–50 yrs), roofing workmanship, 25-year panels, and 10-year solar workmanship all start together — and every penetration is flashed under one agreed spec
One financing scope: the roof rides the solar project's $0-down structures instead of a separate high-rate home-improvement loan
Solar-ready roofing: blocking, conduit paths, and attachment points planned into the new roof, not drilled through it later
One timeline: reroof-to-PTO typically runs 6–10 weeks as a sequence, versus two separate projects months or years apart
Production from day one on a roof that will outlast the panels — no compromise years
How the combined project runs.
- 1
Combined assessment
One visit covers both scopes: roof condition (remaining life, decking, tear-off needs, honest relay-vs-replace call on tile) and solar design (usage modeling, layout, battery sizing). You get one line-item quote with the roof and solar scopes separated.
- 2
Coordinated permitting
Roofing and solar permits move together — where cities allow combined or sequenced filing we use it, and the solar plan is drawn against the NEW roof spec from day one, not retrofitted to old conditions.
- 3
Reroof first
Our licensed roofing partners tear off, fix decking, and install the new roof — with the solar layout already mapped, so blocking, conduit paths, and flashing points go in with the roof instead of through it later.
- 4
Solar follows the roof
The Helios crew mounts on the fresh roof with every penetration flashed to the roofing spec both trades agreed on. No waiting months, no re-mobilization premium — it's one scheduled sequence.
- 5
One inspection wave, one handoff
City inspections, utility interconnection, and monitoring setup close out together. Roof warranty, panel warranty, and workmanship coverage all start the same season — aligned for the next 25 years.
Material options and pricing live on the roofing page and the roof cost breakdown — and if outage protection is part of the plan, the battery goes in on the same schedule.
Solar + roof questions, answered.
- How old can my roof be before solar requires replacing it?
- The working rule: the roof under a solar array should have at least as much life left as the payback period, and ideally 15+ years. For asphalt shingle, that usually means replacing anything past 12–15 years old before panels go on; tile underlayment past 20–25 years is due for a relay; metal and newer flat systems usually pass. We assess remaining life honestly — plenty of roofs we look at are fine, and we say so.
- What does it cost to remove and reinstall solar panels for a reroof later?
- Typically $3,000–$5,000 for a standard residential array — detach, store, reroof, remount, re-commission — plus permit and inspection time, and the risk that an out-of-business installer's workmanship warranty no longer covers the remount. That bill is exactly what doing the roof first avoids.
- Is it cheaper to bundle the roof and solar than do them separately?
- The roof itself costs the same; the savings are structural: no future remove/reinstall ($3,000–$5,000), one mobilization sequence, coordinated permits, and combined financing. Over a decade the bundle typically nets out $4,000–$7,000 ahead — before counting the electricity the solar makes from day one instead of years later.
- Can I finance the roof and solar together?
- Yes — the combined project finances as one scope through our lending partners, $0-down options included. For many homeowners the single monthly payment lands below what the old electric bill plus a standalone roof loan would have cost separately. Cash, loan, and prepaid-lease structures are shown side by side on the quote.
- Who does the roofing work in a bundled project?
- Our licensed roofing partners — vetted Southern California roofing contractors whose license numbers appear on your contract — install the roof, while Helios engineers the solar, manages the schedule, and stands accountable for the whole project. Two specialist trades, one phone number.
- Does a new roof change my solar design?
- It improves it. Designing both at once means the array layout, conduit routing, and attachment blocking are planned into the roof rather than worked around it — cleaner lines, fewer penetrations, better flashing details, and a cool-roof material choice (on flat roofs especially) that can slightly boost panel output by lowering roof-deck temperatures.

One assessment covers both. If your roof has the years left, we'll tell you — and just build the solar.
