Exterior Painting
Exterior Painting: Siding, Trim, Fascia and Doors
Exterior painting for siding, trim, fascia, soffits and doors, anywhere in Texas. The surface is documented first, repairs come before paint, and the product is matched to the surface and the Texas sun.

The short version
- Exterior painting covers siding, trim, fascia, soffits and exposed wood, anywhere in Texas.
- Repairs to fascia, soffit and trim come before paint, because painting first only seals the problem in.
- Exterior painting uses Sherwin-Williams and Benjamin Moore products. Stucco or brick gets the Sherwin-Williams Loxon system.
- Chalked paint must be cleaned and primed before a topcoat, or the new paint loses adhesion within one season.
- If a roof replacement is planned, paint after it, because roofing crews, scaffolding and overspray can damage new paint.

What This Covers
What exterior painting covers
Exterior painting covers siding, trim, fascia, soffits and exposed wood, and it follows any planned roof work.
Walls, Trim and Fascia
Siding, trim, fascia, soffits, and exposed wood surfaces.
Works With Roofing
If a roof replacement is planned, paint after it. Painting before a roof replacement means scaffolding damage, overspray, and potential rework. Sequencing through The Roof Shepherd avoids this.
Surface Behavior
How exterior paint fails in Texas conditions
Our exterior painting uses Sherwin-Williams and Benjamin Moore products. In the Sherwin-Williams lines, depending on the surface and how long the finish needs to last, that typically means SuperPaint, Duration, or Emerald, three tiers of the same family, each formulated to hold color under the UV load Texas delivers. Doors get their own enamels, Emerald Urethane Trim Enamel or fast drying SnapDry, and stucco or brick sections get the Loxon masonry system rather than wall paint.
Sun chalks acrylic paint, temperature swings of 40 to 60 degrees F crack it, and chalked surfaces need priming first.
UV Degradation & Chalking
The Round Rock area averages over 220 sunny days per year with UV index regularly reaching 10 to 11 in summer months. Acrylic paint binders break down under sustained UV exposure, releasing pigment particles as a chalky powder on the surface. Chalking is not cosmetic failure, it signals binder breakdown and means the film can no longer protect the substrate beneath. Repainting over chalked surfaces without priming produces adhesion failure within one season. Our guide to how long exterior paint lasts in Texas explains the research.
Thermal Cycling & Checking
Exterior wood surfaces in Texas cycle through temperature swings of 40 to 60°F between summer nights and peak afternoon readings. Paint films expand and contract with each cycle. When the film has lost elasticity from age or was applied too thick, it checks, a network of fine cracks running perpendicular to the grain. Checked paint cannot be top-coated. The checks allow moisture infiltration beneath the film, and any new coat applied over them will peel as the substrate moves. The wood must be stripped, sanded, and primed before repainting.

Common Questions
What homeowners ask about exterior painting
Should I paint before or after replacing my roof?
After. Roofing crews work with ladders, equipment, and debris that makes contact with exterior siding and trim. New shingle overhangs change drip edge profiles. And if fascia or soffit repairs are needed as part of the roofing scope, those surfaces need to be addressed before paint is applied. Painting first means painting twice, or accepting damage.
How does Texas heat affect exterior paint?
UV intensity in Texas accelerates paint chalking and adhesion breakdown faster than most national paint specifications assume. South and west-facing elevations are most affected. A product rated for 10-year performance in a northern climate may require recoating in 5 to 7 years here, especially if the original surface prep was inadequate. Direct UV on dark colors also causes differential thermal expansion that accelerates cracking at caulk joints.
Does The Roof Shepherd handle painting directly?
Yes. Our painting division does the work. The surfaces are documented first, and the painting scope is defined correctly before any brush is applied.
What does chalking mean on exterior paint, and can it be painted over?
Chalking is a sign that the paint binder has broken down under UV exposure, the film is releasing pigment as a loose powder on the surface. It cannot be painted over without priming first. New paint applied over a chalked surface loses adhesion within one season. The correct sequence is to clean and prime the chalked surface before applying a topcoat.
How long does exterior paint usually last in Texas?
On a well-prepped surface, quality exterior paint typically holds five to ten years here, with south-facing and west-facing walls fading first from sun exposure. Prep and the right product matter more than the brand name on the can. We document the existing surface condition so the next coat is planned, not guessed.
Should exterior repairs to trim and fascia happen before or after painting?
Repairs to fascia, soffit, and trim should come before paint, so the new coat goes onto sound, sealed wood rather than over rot or gaps. Painting first only seals the problem in. We sequence the documentation so repairs and paint happen in the right order.
Do you paint the exterior of commercial buildings?
Yes. We take exterior painting on commercial buildings as well as homes. The walls, trim, and any water damage are documented first, and because roof and gutter problems often show up on exterior paint, we check those before the scope is written. The work is scheduled around your business hours where the job allows.
