Alpha Eagle Roofing installs and repairs composition shingle, clay and concrete tile, standing-seam metal, and low-slope systems (TPO and modified bitumen) across the Bay Area. The right system depends on your roof's pitch, structure, fire zone, Title 24 climate zone and how close you are to the coast; we recommend one after inspecting the roof, with the trade-offs in writing.
The Right Roof for Your Building
Not every roofing system is right for every structure. Pitch, climate, architecture, HOA rules, and budget all play a role. Alpha Eagle Roofing works with all major residential and commercial roofing systems, and we’ll help you choose the one that delivers the best value over the life of your building.
Asphalt & Architectural Shingles
The most widely used residential roofing material in North America for good reason — affordable, durable, available in dozens of colors, and well-suited to Bay Area conditions.
- 3-tab shingles: cost-effective, 25-year rated
- Architectural/dimensional: richer appearance, 30-year rated, better wind resistance
- Impact-resistant: Class 4 rated, often qualifies for insurance discounts
- Designer shingles: mimic the look of slate or wood shake at a fraction of the cost
Clay & Concrete Tile
Iconic in California architecture, tile roofing offers a 50+ year lifespan and exceptional fire resistance. It requires proper structural support — we assess load capacity before recommending tile on any existing structure.
- Spanish/Mission (S-profile) and Flat profile available
- Clay tile: premium product, lightest weight tile, beautiful aged patina
- Concrete tile: more affordable, heavier, excellent durability
Metal Roofing
Standing-seam metal is the fastest-growing roofing category for good reason: 40–70 year lifespan, virtually zero maintenance, and significant energy savings from its reflective surface.
- Standing-seam panels: concealed fasteners, excellent weather resistance
- Metal shingles: mimic shingle or tile appearance with metal’s durability
- Corrugated/exposed-fastener: agricultural and commercial applications
- Finishes: Kynar 500 paint systems with 40-year fade warranties
Flat & Low-Slope Systems
Flat roofs require specialized waterproofing membranes — standard shingles don’t work at low slopes. We install the three dominant commercial flat roof systems:
- TPO (Thermoplastic Polyolefin): Energy-Star rated reflective membrane, heat-welded seams, excellent for commercial roofs
- EPDM (Rubber): Industry standard for residential flat roofs, highly flexible, 20–25 year lifespan
- Modified Bitumen: Multi-layer system ideal for high-traffic roofs and rooftop decks
Choosing the Right System
During your free estimate, we’ll assess your roof pitch, framing, existing system, and local code requirements, then give you a clear recommendation with the trade-offs explained honestly.
