Solar Panel Installation in
Northern Virginia

A solar system mounts directly onto — and penetrates — 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 — 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 — 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 — 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.

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.

Our Solar Installation Process: What to Expect

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 — 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.
