When repair makes sense
- Younger roof with a sound deck
- One leak path (boot, vent, flashing)
- A few blown off or missing shingles, with a matching shingle available
- Repair cost is a small share of a new roof

Residential Roofing & Roof Replacement in San Antonio
A new roof is more than new shingles. It’s a system of decking, underlayment, flashing, ventilation, and edge metal that has to work together. We look at your roof, explain what it needs, and put the full scope in writing. You work directly with us from the first inspection to the final cleanup.
Your roof is a system. Shingles are one part of it.
The shingles are what you see from the street. What keeps water out is everything working together underneath and around them. When one part is skipped or reused, that’s usually where the next leak starts.
- Decking: the wood the roof is nailed to. Soft or rotten sections get replaced, not covered over.
- Underlayment and leak barrier: the layer under the shingles, with extra protection in valleys and around penetrations.
- Shingles: the outer layer that sheds water first and takes the Texas sun.
- Flashing: the metal at walls, chimneys, and transitions that turns water back onto the roof.
- Pipe boots and vents: every penetration is a place water can follow in.
- Ventilation: attic airflow affects heat, moisture, and how long the shingles last in this climate. How vent leaks happen.
- Drip edge: metal at the eaves and rakes that protects the fascia and sends water into the gutter.
- Valleys: where two slopes meet and carry the most water.
- Ridge components: ridge cap and ridge vents at the top of the roof.
Flashing: the details that keep water out
A roof is more than shingles or panels. The details that direct water and protect the transitions are part of the system too, and flashing isn’t an optional accessory. Flashing is one of the parts of a roof that most people never notice until there is a problem. It’s used around chimneys, skylights, walls, valleys, roof penetrations, and other areas where water needs to be directed away from vulnerable points.
Where we look for it:
- Chimneys, dormers, sidewalls and headwalls (roof-to-wall transitions)
- Skylights, roof vents and pipe penetrations, including the pipe boots that seal around plumbing vents
- Valleys
- Drip edge at the eaves and rakes
- Kick-out diverters, where a roof edge ends against a wall, so water goes into the gutter instead of behind the siding
- Anywhere else the roofing meets another surface
On a new roof or a replacement, flashing is part of the job. We replace worn or rusted pieces instead of reusing them, and we don’t count on a tube of sealant where metal belongs. As a roofing and sheet metal shop, we form and install these details ourselves.
One example: an open roof return at the wall isn’t only a leak path. Mice were using the open return on this job. We closed the gap with the right metal detail so water sheds and pests stay out.
Shingle types
We work with both traditional 3-tab and architectural asphalt shingles, along with other asphalt shingle systems. GAF Royal Sovereign® is an example of a traditional 3-tab asphalt shingle. Architectural shingles are thicker, layered shingles with a more dimensional look. Compare shingles in the Roof Guide.
The shingle type also affects how a repair is handled, so we check what’s on your roof before we recommend anything.
Our shingle preferences
GAF is our preferred shingle manufacturer, and Owens Corning is another manufacturer we confidently recommend.
We understand that customers may have a preferred brand, color, product, or existing roofing system. We can accommodate other reputable shingle manufacturers upon request.
The brand may change, but our approach to installation does not. We follow the manufacturer’s installation requirements and maintain the same standards for workmanship, roofing details, and jobsite quality regardless of the shingle brand selected.
Certain qualifying GAF roofing systems are eligible for enhanced warranty options, including GAF’s WindProven™ Limited Wind Warranty. Manufacturer warranties are separate from the installation work performed by SA Metro.
We’ll help you choose a roofing system that fits your property, project, appearance, budget, and warranty requirements.
Repair or replace?
Not every roofing problem requires a complete replacement. We look at the condition of the roof and explain what makes sense: the roof’s age, how much of it is damaged, and the condition of the flashing and deck. On a repair, matching an existing shingle depends on the manufacturer, product line, color, age, and availability.
When replacement makes sense
- Shingles near the end of their life in Texas sun
- Widespread hail or wind damage across several slopes
- Soft deck in several places, or chronic attic moisture
- The same areas patched again and again
New roof installation and replacement
New roof installation
Careful preparation, deck repairs where needed, underlayment, flashing, and attention to the details that keep water out.
Roof replacement
When a roof has reached the end of its useful life or has extensive damage, we plan the replacement with a proposal that lists the work involved.
What’s included in a replacement
A replacement is more than new shingles. Depending on your roof, the scope can include tear-off, deck repairs, underlayment, flashing, ventilation, drip edge, ridge components, disposal, and the permit. We explain what’s included in your proposal before work begins. As a GAF Certified™ contractor, qualifying roofs may be eligible for GAF warranty options such as the System Plus Limited Warranty, subject to GAF’s product and program requirements.
