“After hail hit our area, our extended family used Atrium for three new roofs in two months. They were prompt and worked hard to get us the maximum insurance reimbursement — a real contrast to the workmanship we saw going up elsewhere in the neighborhood.”

San Antonio Roofing Starts With an Engineer-Led Inspection.
Before recommending repairs or replacement, we examine the whole roofing system. Our free 53-point assessment looks beyond the shingles: flashing, attic conditions, ventilation, drainage, and visible structural concerns. Every assessment report and proposal is reviewed by Jose Puente, a civil engineer. You get documented findings and decide what your roof actually needs.

Certified by the manufacturers we install.
These aren't badges we bought. Each tier sets what we're allowed to install and which warranty we can register in your name.





Your Roof Should Come With Proof.
When the work is done, you should have the paperwork that shows what was installed. Here is what may be in your Power Package.
Documents vary by roofing system. Every replacement includes a certificate of completion and a paid invoice. Shingle replacements also include the supplier's material invoice. Impact-resistant certification is included only when the installed system is impact-rated. A registered manufacturer system warranty is included only where the system and certification tier qualify.

A roof isn’t shingles. It’s a system.
Most roof failures don’t start with the shingle. They start with ventilation, flashing details, underlayment choice, or decking that should have been replaced.
We approach every roof as a system — deck, barrier, ventilation, flashings, and finish working together.
We look beyond the shingles
- Roof surface and edges. Every slope documented, the field shingles, the eaves and rakes, and the ridge and hips.
- Flashing, penetrations and drainage. Chimneys, pipe boots, vents, valleys, gutters and downspouts, plus the soft metals around the house.
- Attic, ventilation and visible structure. The attic from the inside, a ventilation calculation, and what the deck and framing show.
Five systems. One of them fits your house.
Each one is a full assembly we spec and install — not a shingle you pick off a board.
Our standard-tier engineered system: Class 3 impact-resistant shingles, matching ridge, enhanced ventilation, and a registered manufacturer warranty.
Our Class 4 engineered system: UL 2218 Class 4 impact-resistant shingles, matching ridge, enhanced ventilation, and a registered manufacturer warranty.
Class 4 built with SBS-modified rubberized asphalt — the same UL 2218 impact rating as IMPACTSHIELD™, reached through a different material-science path.
Our TAMKO HailGuard system: UL 2218 Class 4 impact-rated, built around TAMKO's hail-focused ImpactCore technology and Pro Platinum standing.
Our energy-focused engineered system, offered as a Class 3 cool-roof shingle path or a Class 4 standing seam metal path.
San Antonio homeowners, in their own words.
Published reviews from neighbors we’ve worked for, lightly trimmed for length.
We never hide pricing.
Every roof is different, but you deserve a starting range before anyone knocks on your door. Here’s what real San Antonio and Hill Country roofs cost — and what moves the number.
Military households get a flat $500 off a roof replacement.

Thermal cycling. Wind uplift. Hail energy. Attic pressure. We break down the physics of why roofs fail — and how ours are engineered so yours doesn’t.

We write a guide for every place we work.
Soil, storm exposure, and roof age differ street to street — so the guides do too. Find your city below.
