What a Residential Roof and Solar Combo Actually Costs You
Mount Washington homeowners ask us the same question: is it cheaper to do the roof first, then solar later? Almost never. Doing them separately means two mobilizations, two permit fees to Los Angeles County, and a solar crew drilling into a roof that wasn't prepped for the load. 90065 has a mix of 1950s ranch homes and newer hillside builds, and both need different setups. A Residential Roof and Solar Combo done together runs $28,000 to $65,000 depending on square footage and panel count - but federal tax credits cover 30% off the solar portion. Split the jobs and you lose coordination discounts, add weeks to your timeline, and risk voiding the roofing warranty when solar gets added later. One job. One cost. Done right.
— The benefits
6 Reasons Mount Washington Homes Need This Combo
Lower SCE Bills Fast
90065 SCE customers pay some of the steepest tiered rates in LA County. A Residential Roof and Solar Combo locks in your generation while eliminating the roof issues that let heat bleed into your attic and spike cooling costs.
Hillside Sun Exposure Works For You
Mount Washington rooflines face south and west at angles that maximize solar yield. We position panels around existing penetrations and ridge lines to pull every usable hour of direct sun without compromising the new roof below.
One Permit. Faster Timeline.
Los Angeles County combined roof-and-solar permits process in 5 to 7 business days. Pulling them together saves you a second inspection cycle and keeps the project on one continuous schedule instead of two separate jobs months apart.
Manufacturer Warranty Stays Intact
Drilling into an existing roof for solar attachments can void your shingle warranty. Installing both at once means flashings, underlayment, and attachment points are all spec'd together - so every warranty covers everything from day one.
Santa Ana Wind Ratings Matter
Hillside homes in 90065 take direct Santa Ana wind loads. Green Conception uses Class 4 impact-rated shingles and code-compliant racking rated for high-wind zones, so neither the roof nor the array moves when gusts hit hard.
30% Federal Tax Credit Applies
The ITC covers 30% of your solar installation cost when filed correctly. Done as a Residential Roof and Solar Combo, the tax credit calculation includes all solar-related roof work - a number most standalone solar quotes miss entirely.
01
Free Roof and Solar Inspection
We visit the Mount Washington property, check the existing roof condition, attic structure, and electrical panel, and pull shading data for the specific 90065 address before quoting anything.
02
Combined Design and Permit Filing
Roof spec and solar layout get drawn together and submitted to Los Angeles County as a single permit package. That cuts approval time and removes redundant inspection visits from the schedule.
03
Roof Tear-Off and Installation
Old material comes off, decking gets checked and replaced where needed, and new underlayment and shingles go down before any solar hardware touches the roof. Sequence matters here.
04
Solar Racking and Panel Install
Racking attaches through fresh flashing points built into the new roof. Panels go up, wiring runs to the inverter, and the system gets connected to the existing SCE meter configuration.
05
City Inspection and System Activation
Los Angeles County inspects both systems together. After sign-off, SCE processes the interconnection agreement and the system goes live - usually within 2 to 3 weeks of final inspection.
— How it works
How Green Conception Runs a Combo Project in Mount Washington
Every Residential Roof and Solar Combo starts with a site visit, not a sales pitch. We walk the roof, check the attic, measure pitch and rafter spacing, and pull satellite shading data for the 90065 address. From there, we build a combined scope - roofing materials, panel layout, racking spec, and electrical design in one document. Los Angeles County permit applications go in together, and typical approval runs 5 to 7 business days. Roofing comes first: tear-off, deck inspection, underlayment, and new shingles. Solar racking and panels go on next, same week in most cases. Final inspection covers both systems. Green Conception carries an active CA contractor license and full liability insurance on every job. No deposit required to get your written quote. Just a no-obligation estimate and a clear timeline before anything starts.

More Services for 90065 Homes



Attic Insulation Upgrade
Mount Washington hillside homes lose serious cooling efficiency through under-insulated attics. After a roof replacement, we can add blown-in or batt insulation that works with your new roofline and reduces the load on your HVAC - cutting energy use before your panels even start generating.
Battery Storage Systems
A battery backup paired with your Residential Roof and Solar Combo keeps your home running through SCE outages, which hit 90065 during high-wind events more than most of LA. We install and permit battery systems alongside or after your solar array for full energy independence.
- Why us
Why Mount Washington Calls Green Conception

How We Think About Roofs and Solar Together in Mount Washington
A roof and solar array are one system, not two projects that happen to share a surface. Mount Washington's hillside geometry, sun exposure, and wind load require decisions made together - not handed off between separate contractors who never talk to each other.
"A combined roof and solar job in Mount Washington done wrong costs twice - once to fix the roof leak under the racking, once to redo the install. We design them as one system because that's the only way it holds up on a hillside long-term."

— Common questions
Common Questions About Residential Roof and Solar Combo in Mount Washington
How much does a combo project cost in 90065?
A Residential Roof and Solar Combo in Mount Washington typically runs $28,000 to $65,000 depending on roof size, panel count, and existing electrical setup. The 30% federal ITC applies to the solar portion, and some LA County rebates stack on top. Get a written quote before comparing numbers from different contractors.
Do I need a new roof before adding solar?
Not always, but often yes. If your Mount Washington roof has less than 10 years of life left, adding solar on top locks in a future tear-off cost that's far higher than doing it now. Green Conception checks roof condition during the free inspection and gives you a straight answer before any commitment.
How long does the LA County permit take?
Los Angeles County combined roof-and-solar permits typically process in 5 to 7 business days when submitted correctly. Missing documentation or incorrect drawings adds weeks. Green Conception files both permits together as a single package, reducing back-and-forth with the building department at the 90065 jurisdiction level.
Will solar void my new roof warranty?
Solar installation can void a shingle warranty if done by an uncredentialed contractor or without proper flashing. Installing both together with Green Conception means racking attachments are built into the roofing spec from day one - so the manufacturer warranty covers the full assembly, not just the shingles around it.
Can Mount Washington homes handle solar on steep pitches?
Yes. Steep-pitch roofs common in 90065 often face optimal solar angles for LA's sun path. Green Conception uses racking systems designed for pitches up to 45 degrees, and we account for hillside wind loads in the mounting spec so the array holds through Santa Ana events without issue.
What happens during the final inspection?
A Los Angeles County inspector reviews both the roofing and solar installation against permitted drawings. They check flashing, deck fastening, racking attachment, wiring, and inverter placement. Green Conception coordinates the inspection date and is on-site when it happens. Passing on the first visit is the goal - and our standard.
How does SCE interconnection work after install?
After the county inspection passes, Green Conception submits SCE's interconnection application with the system specs and electrical diagrams. SCE reviews and approves the connection, typically within 2 to 4 weeks. Once approved, they update the meter and the system goes live. 90065 homeowners start generating from that point forward.
Is the 30% federal tax credit real for combo projects?
Yes. The Investment Tax Credit covers 30% of your solar installation cost, including solar-related roof work done as part of the same project. A Residential Roof and Solar Combo done together maximizes what qualifies. Talk to your tax professional about filing - Green Conception provides all documentation needed to support the credit claim.
