Roof-Mount Solar Panel Installation in Bastrop & Fayette County, TX

The most common way to go solar — panels mounted directly to a roof that already gets good sun. We check your roof's material, angle, and remaining lifespan before recommending it, not after you've already bought equipment. If your property has open land instead, see Ground-Mount Solar Installation.

Sized Around Your Actual Roof and Usage — Not a Template
Quick Check

Does Your Situation Sound Like This?

Straightforward candidate. A roof with plenty of life left is the simplest case — we go straight to sizing the system around your usage and mapping sun exposure.

Worth addressing first. If a re-roof is likely within the next few years, doing that before panels go on avoids paying twice to remove and reinstall them later.

Common on rural Central Texas homes. Standing-seam metal typically mounts panels with clamps that grip the seam directly — zero roof penetrations.

The most common roof type we install on. Asphalt shingle roofs use flashed mounting points designed to keep the manufacturer's warranty intact, not caulked-on brackets.

Not automatically disqualifying. Partial shade at certain times of day can often be worked around with panel placement — heavy, all-day shade is the real limiting factor.

Worth mentioning up front. It's cheaper to size a system for that future load now than to expand the array later.

What Actually Determines Fit

What Determines If Your Roof Actually Works

Material and Mounting Method

Roof-mount isn't one-size-fits-all — the roof itself is the variable that decides almost everything else. Standing-seam metal roofs, common on rural Central Texas homes, usually mount panels with clamps that grip the seam directly, with zero roof penetrations. Asphalt shingle roofs use flashed mounting points instead: a bracket bolted through the shingle into the rafter, with flashing installed under the shingle course above it — not just caulked on top — which is the detail that actually keeps a roof-mount installation from leaking. Tile and flat roofs need their own hardware and aren't always a fit; we say so plainly rather than forcing an installation that doesn't suit the roof.

Age and Remaining Life

A roof that needs replacing in the next few years is worth re-roofing first — removing and reinstalling panels for a later re-roof adds real labor cost that's avoidable with the right sequencing. As a rough industry rule of thumb, an asphalt shingle roof with more than 10 to 15 years of expected life left is a reasonable candidate for solar now; anything closer to the end of its service life is usually worth replacing before panels go on, not after. We check this during the on-site assessment rather than guessing from the roof's age alone.

Structural Load and Orientation

Panels add real weight, so the roof's structure gets checked, not assumed — most residential roofs built to current code handle it without issue, but we confirm rather than guess, especially on older homes or unconventional framing. Orientation matters too: south-facing sections with several hours of unobstructed sun through the day are the strongest candidates, though east- and west-facing roofs can still work well, usually with a modest tradeoff in total output rather than being disqualifying.

The Real Objection

Will This Void My Roof Warranty or Cause a Leak?

This is the single biggest objection homeowners raise before seriously considering roof-mount, so it gets answered directly instead of glossed over. The real failure point in roof-mount installations isn't the panels — it's improper flashing: brackets sealed with caulk on top of the shingle instead of flashed underneath the course above, or a missing flashing boot where a conduit passes through the roof. Done correctly — flashing installed the way the shingle manufacturer specifies — a roof-mount install doesn't compromise the roof's warranty or watertightness. That's a workmanship detail worth asking about directly before anyone installs on your roof, not something to take on faith.

Costs & Incentives

What Solar Actually Costs Right Now

Pricing

No flat installed-cost number posted sitewide — system size and site conditions change the real number too much to mean anything generic. Every quote comes from the free on-site assessment.

Federal Tax Credit

The federal Residential Clean Energy Credit ended for systems installed on or after January 1, 2026 (One Big Beautiful Bill Act, per IRS FS-2025-05). Older marketing referencing a 30% federal credit is outdated.

Texas Property Tax Exemption

Still active. Texas Tax Code §11.27 exempts the added value of a solar energy device from your home's appraised value — filed via Form 50-123 with your county appraisal district (Bastrop CAD or Fayette CAD). Not automatic.

Panel & Inverter Warranty

Panels typically carry a 25-year performance warranty. Inverters typically carry 10 to 15 years for a string inverter and are usually the first component that needs replacing — see Solar Inverter & Micro-Inverter Installation.

Top Questions, Ranked

Roof-Mount Solar FAQ

1. Is my roof actually a good candidate for solar?
South- or west-facing sections with several hours of direct, unobstructed sun are the strongest candidates. A roof that's shaded most of the day or faces north can still work — usually it just means fewer panels at full output, or it points toward a ground-mount system if the property has open land. We check the actual roof on-site rather than estimating from satellite imagery.
2. Will solar panels void my roof warranty or cause leaks?
Not when the mounting is flashed correctly — under the shingle course above the bracket, not caulked on top. The two most common causes of solar-related roof leaks are exactly that: improper flashing placement or a missing flashing boot at a conduit penetration. That's a workmanship detail, not an inherent risk of roof-mount installation itself.
3. What roof types work best — asphalt shingle, standing-seam metal, tile, flat?
Standing-seam metal roofs, common on rural Central Texas homes, typically mount without any roof penetrations at all. Asphalt shingle roofs use flashed mounting points designed to keep the warranty intact. Tile and flat roofs need different hardware and aren't always a good fit — we'll say so plainly rather than forcing an installation that doesn't suit the roof.
4. Should I re-roof before installing solar, or can it wait?
If the roof has more than roughly 10 to 15 years of life left, most homeowners install solar now. If a re-roof is likely within the next few years, doing that first avoids paying twice to remove and reinstall panels later. We check this during the on-site assessment before recommending either path.
5. Which roof direction and pitch produce the most power?
South-facing roofs with several hours of unobstructed daily sun are generally the strongest performers. East- and west-facing roofs can still work well, typically with a modest reduction in total output rather than being disqualifying. Roof pitch matters less than orientation and shading in most cases.
6. How much weight can my roof structurally support?
Most residential roofs built to current code handle the added weight of a solar array without issue, but this gets confirmed during the on-site assessment rather than assumed — especially on older homes or unconventional framing.
7. How long does a roof-mount installation actually take?
Physical installation is typically a short process measured in days, not weeks — the paperwork (permitting and utility interconnection) usually takes longer than the physical install itself. See Solar Permitting & Utility Interconnection for that timeline.
8. What happens to my system during a power outage?
A standard grid-tied roof-mount system shuts off automatically during a grid outage, even with the sun out — that's a safety requirement, so the system doesn't backfeed power into lines utility crews may be working on. Battery storage is what keeps power flowing during an outage; see Battery Storage & Backup Power.
9. Can I add more panels later if my usage grows — an EV, a pool, a workshop?
Sometimes, depending on available roof space, the original inverter's capacity, and your utility's interconnection limits. It's worth mentioning any planned future load during the initial system design so the install isn't sized only for today's usage.
10. Do I need a permit, and who handles that paperwork?
Yes — every residential roof-mount install needs a county (and sometimes city) permit plus a signed utility interconnection agreement before it can be legally turned on. We handle both. Full detail is on the Solar Permitting & Utility Interconnection page.
