Alamo Roofing: Don't Call the Wrong Building Department

Alamo isn't a city. That's the first thing to know, and it's the single most common thing we correct on our intake calls. When an Alamo homeowner types "Alamo building department" into Google, they get sent to half a dozen wrong places. Danville's office, Walnut Creek's portal, sometimes even San Ramon's. The right answer is Contra Costa County Department of Conservation and Development at 30 Muir Road in Martinez. Alamo is unincorporated. Every permit runs through the county.

That matters because the county permit process is different from the town processes in Danville, Walnut Creek, or Orinda. The online portal is the county's ePermits Center. The plan checkers handle a bigger geographic area and a wider variety of projects. The fees are set by county schedule, not city schedule. And the inspectors are county staff, not town employees. Once you understand that, the rest of the process is straightforward.

The other thing about Alamo is that most of it sits inside the VHFHSZ. Round Hill Country Club, Alamo Oaks, the hills above Stone Valley Road, and everything edging toward Las Trampas Regional Wilderness, all Chapter 7A territory. We've covered the county permit details in our Alamo roofing permits guide. This page is about the work itself.

Our Roofing Work in Alamo

We've been working in Alamo since 1988, and our crews have pulled more roofing permits through Contra Costa County's Martinez office than most contractors have pulled total permits in their careers. We know the county plan checkers. We know which Round Hill review board members still work through physical color chips and which ones accept digital submissions. We know the back routes around Stone Valley Road when there's traffic on Danville Boulevard.

Last fall we replaced a 68-square tile roof on a Round Hill Country Club estate. The original 1988 concrete tile had reached the end of its underlayment life, the tiles themselves were fine but the felt below was done. We did a full lift-and-relay with new synthetic underlayment, new battens, copper valley flashings (the originals were rusted through), and 12% new tile to replace cracked pieces. The Round Hill architectural review committee approved the scope in three weeks. On-site work took 16 working days. Chapter 7A documentation delivered to the homeowner's insurance carrier as standard.

In early 2024 we did an Alamo Oaks project that started as a leak diagnosis and turned into a full replacement. The owner had been patching a chimney flashing leak for four years. We got up there and found that the real issue was the cricket behind the chimney had rotted through completely, water was running around the chimney into the attic, then migrating along a rafter and dripping 15 feet away from its actual entry point. Classic misdiagnosis. We rebuilt the cricket, replaced 30 squares of deteriorated shingle around the affected area, and installed a proper Class A fire assembly since the property was in the VHFHSZ.

And one Round Hill customer called at 2 a.m. during the January 2023 atmospheric river series. Water was pouring into her primary bedroom through a can light. We staged a tarp by 6 a.m., traced the leak to a failed pipe jack boot the next day, and had the permanent fix done by the following weekend. Emergency calls in Alamo during a storm series are about response time more than technical difficulty. Response time is why we stage materials in Concord, 20 minutes from most Alamo addresses via Livorna Road.

Alamo Climate and Roof Failure Patterns

Alamo averages 22 inches of rain per year, less than Lafayette or Moraga but more than Danville. Summer highs regularly hit 92-100°F. Diablo wind events in October and November can push gusts above 50 mph on the upper elevations. The climate combination, hot dry summers, wind, and concentrated winter rain, creates specific failure patterns:

• Underlayment failure under tile roofs is the dominant Alamo premium-home issue. Tiles from 1985-2000 builds are reaching the point where the felt below needs replacement while the tile still has decades of life.
• Ridge cap wind lift on Round Hill and Stone Valley properties during Diablo wind events.
• Cricket and chimney saddle failures on older custom homes where the original 1970s detailing wasn't adequate.
• Pipe jack boot UV cracking around year 12-15, cheap to replace during a re-roof, expensive to chase down as a leak later.
• Valley metal rust-through on 1980s concrete tile roofs where the original galvanized valleys have reached their end of life.

Permits and the County Process

Contra Costa County permits come from the Department of Conservation and Development at 30 Muir Road in Martinez, with online submissions through the ePermits Center portal. Standard residential re-roof permits run $385-$560 for a typical 2,400-3,200 sq ft Alamo home with asphalt shingle, or $540-$820 for concrete or clay tile due to higher material valuation.

Straightforward re-roofs are typically issued same-day or within 24 hours when the application is complete. Projects with structural work, heavy material upgrades, or Chapter 7A fire compliance review can take 2-3 business days for plan check. We've written a full guide to the process in our Alamo roofing permits guide, worth reading before you start.

Round Hill Country Club and Stonegate both layer architectural review on top of the county permit. Round Hill's review board is thorough — they check color palettes, ridge profiles, and require that adjacent homes maintain visual consistency. We track which board members respond to which submission formats and time the paperwork accordingly. Our Alamo HOA guide covers the specifics.
