What Metal Roofing Involves

Metal roofing is a full roof replacement using either standing-seam steel panels or exposed-fastener corrugated sheets. The standing-seam option—panels running vertically with concealed clips—is the gold standard for residential work. We install 24-gauge steel with a PVDF (Kynar 500) finish, which resists fading and chalking far better than SMP polyester coatings. For homes near San Ramon Creek where fog brings coastal moisture, aluminum panels offer zero corrosion risk, though they cost more per square.

Stone-coated steel, like Decra or ATAS products, mimics the look of tile or shake while keeping the weight and fire rating of steel. The tear-off process removes the old shingle layers down to the deck. We inspect the roof deck for rot or decay—common in 1970s Spanish-style stucco homes in Windemere and Canyon Lakes—and replace any compromised plywood before laying a self-adhered ice and water shield over the entire roof, not just the valleys. This is a critical step because our winter rainstorms push water uphill under shingles; the self-adhered membrane seals every nail hole.

Panels are cut to exact roof measurements on site, so there are no end laps on most roofs. We use ring-shank nails for the starter course and any exposed-fastener applications, and each panel is screwed with a neoprene washer that seals itself. The field course overlaps the previous panel by one rib, and the staggered courses at hips and ridges are hand-sealed with urethane caulk. A proper metal roof has no exposed fasteners on the field—that's what separates a 50-year system from a 25-year one.

Signs You Need Metal Roofing

If your current roof is showing granule loss in the gutters, widespread cracking, or curling shingles, it's approaching end-of-life wear. Asphalt shingles in San Ramon typically last 15–20 years because our UV index is brutal; the sun erodes the granules, and the fiberglass mat flakes and peels. When you see daylight through the decking in your attic, the roof is no longer protecting the structure. Water seeps through the smallest gaps, wicks along the roof deck, and rots the rafters from the inside out.

Another sign is rising energy bills in July and August. A dark asphalt roof absorbs heat, and your AC works overtime. Metal roofing reflects up to 70% of solar radiation—a measurable difference in a two-story tract home in Norris Canyon or a custom estate in Country Club Estates. If you're planning to stay in your home for more than 10 years, the switch to metal makes financial sense. Also, if you've had three or more repair patches in the last five years, you're throwing money at a system that's ready to fail.

Our Metal Roofing Process

Step one is a detailed site inspection. We measure every roof plane, check the deck thickness, and note any existing rot or sag. We photograph the entire roof and provide a written quote that lists panel type, gauge, finish, and estimated timeline. No vague bids.

Step two is the tear-off. We strip the old shingles, underlayment, and flashing, then haul everything away. We also run a magnetic nail sweep across the yard—old roofing nails in the lawn are a puncture hazard for tires and bare feet. Step three is deck repair. We replace any rotted plywood with CDX grade, and if the deck has settled or sagged, we sister new rafters to level it.

Step four is installation. We start with the starter course at the eaves, then work up the roof in staggered courses. Each panel is screwed, and the ridge cap is installed with a vented closure that allows attic airflow. Step five is a final walkthrough. We check every seam, every flashing detail, and every fastener. We clean the gutters and the job site. The entire job for a typical 2,000-square-foot ranch takes 3–5 days, depending on weather.

Cost Considerations in San Ramon

Metal roofing costs between $8 and $15 per square foot installed, depending on panel type and complexity. For a 2,000-square-foot roof, that's $16,000 to $30,000—roughly 2.5 times the cost of architectural asphalt. But the lifespan is 40–50 years compared to 15–20, so over 40 years you're paying less per year. Standing-seam with a PVDF finish runs at the top of that range; exposed-fastener panels with an SMP finish sit at the bottom. Aluminum is about 20% more than steel.

Permits in San Ramon run about $300–$500, and we include that in the quote. Hail damage is rare here—no recorded tornado history—but occasional hailstorms can dent a soft aluminum panel. We recommend 24-gauge steel for impact resistance. Financing is available through third-party lenders, and many homeowners recoup 60–80% of the cost in resale value.

Warranty & Insurance

Manufacturer warranties for metal roofing are strong. McElroy Metal and ATAS offer 40-year finish warranties against fading and chalking, plus a 50-year substrate warranty against corrosion. We register the warranty with the manufacturer after installation, so it's fully transferable if you sell your home. Our workmanship warranty covers the installation for 10 years—leaks at seams or flashings are repaired at no charge.

If you're replacing a roof after storm damage, your homeowner's insurance may cover part of the cost. We document the damage with photos and provide a detailed estimate that your adjuster can use. We work with most Contra Costa County insurance carriers and can meet your adjuster on site. If your current roof is over 20 years old, insurance may only pay for the depreciated value of asphalt—the upgrade to metal is an out-of-pocket difference, but many homeowners choose it to avoid a second replacement in 15 years.

Signs You Need Metal Roofing

⚠

Granules in the Gutters

When asphalt shingles shed granules, they're losing their protective layer. In San Ramon's hot summers, this accelerates—you'll see black streaks in your downspouts after every rain.

⚠

Curling or Cracking Shingles

UV radiation causes shingle edges to curl up and crack. Once the fiberglass mat is exposed, water seeps in and wicks along the deck, rotting it from beneath.

⚠

Daylight Through the Attic

If you see light coming through the roof deck from inside, the shingles and underlayment have failed. This is a direct path for water intrusion during winter storms.

⚠

Rising Cooling Bills

An asphalt roof absorbs heat, forcing your AC to work harder. Metal reflects solar radiation, cutting attic temperatures by up to 25 degrees—a big deal in July.

⚠

Roof Age Over 15 Years

Most asphalt roofs in San Ramon last 15–20 years. If yours is in that range and showing any of these signs, it's more cost-effective to replace it with metal than to patch it again.

⚠

Multiple Patches in 5 Years

Three or more repairs in five years means the system is failing. Each patch adds weight and stress, and the next leak could be the one that rots a rafter. Metal ends the cycle.
