Solar Panel Installation in
Northern Virginia

A solar system mounts directly onto โ€” and penetrates โ€” your roof, so what’s
underneath matters as much as the panels on top. Impact Exteriors is a roofing
contractor and solar installer, which means we assess your roof before a
single panel is mounted.

Most solar companies sell equipment. We install it on a roof we understand. Solar and roofing are inseparable โ€” a panel system is anchored through your roof and expected to stay there for 25 years or more. As a licensed roofing contractor who also installs solar, Impact Exteriors is one of the few teams in Northern Virginia qualified to evaluate both halves of the project. Before we recommend a system, we assess the roofing system that will carry it.

Roofing Contractor First, Solar Installer Second

Our strongest qualification is not that we install more solar than anyone else โ€” it is that we understand what is underneath it. We assess the roofing system before adding equipment that could remain there for decades.

That means we evaluate the condition of your shingles and decking, confirm the roof has enough remaining life to justify mounting panels, and install every penetration correctly so the system never becomes a source of leaks. If your roof is nearing the end of its life, we will tell you โ€” and we can replace it first, often bundling both projects under one responsible team.

Many of our solar customers first found us as their roofing company in Alexandria, VA, which is exactly why they trusted us with a second major investment on the same home.

Why the Roof Comes First

Serving the Full DMV Region

We install across Northern Virginia and into Maryland, from established Alexandria neighborhoods to newer developments further out. One local team handles your project start to finish.

What We Evaluate Before Installing Anything

A responsible solar installation depends on far more than the panels themselves. These
are the factors we assess before recommending a system for your home.
Roof Suitability

Not every roof is a good candidate for solar. We confirm your roof structure and pitch can safely support the added load before recommending a single panel.

Roof Age

A roof near the end of its service life should usually be replaced before panels go on. We tell you honestly whether to replace first rather than mounting over aging materials.

Roof Orientation

South-facing roofs capture the most sun, but east- and west-facing exposures can still perform well. We map orientation to realistic production before sizing anything.

Shading

Trees, chimneys, and neighboring structures cast shade that reduces output. We assess shade patterns across the day so your system is sized for what your roof actually receives.

Electrical Capacity

Your existing electrical panel must accommodate the added circuit. We check capacity and flag any panel upgrade needed before installation begins.

Panel & System Sizing

System size is matched to your actual energy usage and available roof space, not a one-size-fits-all package built around a sales target.

Inverter Selection

String, microinverter, or optimizer โ€” we recommend the inverter type that fits your roof's shading and layout, not whatever a vendor happens to stock.

Permitting

We handle building and electrical permits with your local jurisdiction from start to finish, so you never chase paperwork.

Utility Interconnection

We manage the utility approval and net-metering application so your system is properly connected to the grid and credited correctly.

Monitoring

Production monitoring keeps you informed of how your system performs year after year and flags underperformance before it becomes a surprise.

Roof Penetrations

Every mounting point is a penetration through your roof. We flash and seal each one correctly so the system never becomes a leak waiting to happen.

Roofing Warranty Implications

Improper mounting can void a roof warranty. Because we are roofers, we mount in a way that preserves your roofing warranty rather than undermining it.

Solar Warranty

We specify equipment with manufacturer warranties and stand behind our own workmanship with clear, written coverage.

Roof Replacement Before Solar

If your roof needs work, we replace it first โ€” often bundling both projects for a cleaner result and a single responsible team.

Removal & Reinstallation

If roofing work is ever needed after your system is up, we remove and reinstall it safely โ€” a service many solar-only companies simply do not offer.

Financing

We walk you through financing options at a high level so you understand the real monthly cost and payback before you commit.

Our Solar Installation Process: What to Expect

Roof & Site Assessment

We inspect roof condition, age, orientation, shading, and electrical capacity to confirm your home is a good fit for solar before recommending anything.

System Design & Sizing

We design a system matched to your energy usage and available roof space, selecting the right panels and inverter type for your specific layout.

Permitting & Interconnection

We handle building permits and utility approval on your behalf, keeping the project moving without you chasing paperwork.

Installation

Panels are mounted with correctly flashed penetrations. Most residential systems are physically installed within one to two days once permits clear.

Inspection & Activation

Final inspection, utility sign-off, and activation โ€” with monitoring set up so you can see production from day one.

Ongoing Support

Monitoring, warranty coverage, and a single point of contact if anything ever comes up after the system is live.

Why Homeowners Trust Us With a Decision This Big

Solar is a major investment, and it should not feel like a high-pressure sales conversation. We have built our reputation on transparency, which means you will never hear vague promises about savings or pressure to sign before you are ready. Every recommendation is backed by real numbers pulled from your roof, your usage, and your goals โ€” not a script.

That approach has earned us 150+ five-star Google reviews from homeowners across the region, many of whom started with a simple question and ended up with a system they actually understand. We would rather spend extra time explaining how your system works than rush you into a decision you are unsure about six months later.

Frequently Asked Questions About Solar

How is a solar panel cost estimate calculated?
We factor in roof size, orientation, shading, energy usage, and equipment tier, then walk you through actual numbers during an on-site visit rather than a phone quote.
Do I need a new roof before going solar?
Not always. Our team checks your roof’s condition and remaining lifespan first. If replacement is the smarter long-term choice, we’ll recommend it before mounting equipment.
Will installing solar void my roof warranty?
It can, if panels are mounted by a company that does not understand roofing. Because we are a roofing contractor, we install mounting points in a way designed to preserve your roof warranty.
What happens if my roof needs repairs after solar is installed?
We remove and reinstall the system safely around the roofing work, then restore it to full operation. Many solar-only installers do not offer this service.
Which roof orientation works best for solar?
South-facing roofs generally capture the most sun, but east- and west-facing roofs can still be cost-effective. We assess your specific orientation and shading to estimate realistic production.
How long does installation typically take?
Most systems are physically installed within one to two days once permits are approved, though the full timeline includes permitting and utility interconnection.
What financing options are available?
We offer several financing paths designed to fit different household budgets, explained clearly before you commit so you understand the real monthly cost.
Will solar actually lower my electric bill?
For most homeowners, yes. Actual savings depend on system size, orientation, shading, and your energy usage, but many customers see a noticeable drop starting the first billing cycle.
