At Wonderlin Roofing Systems, we know roofing isn’t just shingles and nails. It’s your family’s safety. Your peace of mind. And for us, it’s a legacy. Since 1992, we’ve protected homes throughout Castro Valley with a process grounded in craftsmanship, honesty, and crystal-clear communication. Here’s exactly what to expect when you trust us with your roof.
Step 1: The Honest Evaluation
Every great job starts with the truth. We begin with a no-pressure, on-site inspection to assess the condition of your roof. Whether it’s a worn-out shingle, hidden leak, or storm damage, we get to the root of it—fast.
Our licensed experts inspect everything from the ridge cap to the gutter line. We check for cracked flashing, sagging sheathing, soft spots, and signs of water intrusion. We photograph any findings and explain what they mean in plain English.
Why it matters: Our evaluations are thorough and transparent. If your roof just needs a repair, we’ll tell you. If it’s time for a complete replacement, we’ll explain precisely why, with photos and a detailed quote.

Step 2: Custom Proposal & Timeline
Once we understand your roof needs, we build a clear proposal tailored to your home, not a cookie-cutter estimate. You’ll get:
- A detailed scope of work
- Material options (we specialize in composition, tile, and wood)
- Project timeline
- Total investment with no surprise fees
We help you choose the right materials based on your home’s architectural style, budget, and performance goals. Composition shingles (like architectural asphalt) are popular for their durability and cost-effectiveness. Tile offers unbeatable longevity and a classic look. While rarer now, wood shingles are still favored in historic homes and provide excellent insulation.
Why it matters: You deserve to know what you’re getting, what it costs, and when it’s happening. That’s how trust is built.

Step 3: Preparation & Protection
Before we lift a single shingle, we prep your property like it’s our own:
- Cover landscaping, decks, windows, and AC units with tarps
- Set up jobsite signage and parking plans to minimize disruption
- Deliver and stage roofing materials for efficient access
- Pull and post permits as required by local code
We coordinate dumpster delivery and placement, keeping pathways clear and debris contained. We also notify neighbors if necessary, so everyone knows what to expect.
Why it matters: A clean, protected site creates a safe, efficient install. It also shows respect for your home and neighborhood.

Step 4: Professional Installation
Here’s where experience meets precision. Our crew, led by seasoned roofers who have been with us for decades, executes each install with skill and care:
- Carefully remove old roofing, inspecting for rot, mold, or damage
- Replace or reinforce damaged decking
- Install synthetic underlayment and ice/water shields where needed
- Flash chimneys, vents, skylights, and valleys
- Nail down shingles or tiles according to the manufacturer’s specs and local code
- Install ridge caps, drip edges, and proper attic ventilation
We work in sections, which allows your roof to stay weather-tight even during multi-day installs. Daily cleanup and end-of-day inspections ensure everything stays tidy and on track.
Why it matters: The difference between a good roof and a great one is what you don’t see. We sweat the details so your roof lasts.

Step 5: Final Walkthrough & Warranty
Once the job’s complete, we don’t just pack up and go. We do a thorough cleanup, magnet-sweep for nails, and walk the job with you to ensure every detail meets our standards (and yours).
We’ll review the full scope of work completed and answer any final questions you have. You’ll also receive:
- A workmanship warranty (ours exceeds state requirements)
- A manufacturer’s materials warranty (up to 50 years, depending on brand)
- A maintenance guide to prolong your roof’s lifespan
We’ll show you how to keep valleys clear and gutters clean and spot potential issues early so small problems never become big ones.
Why it matters: A warranty is only as good as the people behind it. We’ve been here 30+ years and’ll be here if you ever need us.

FAQs About Roof Installation
How long does the roof installation take?
Most residential projects take 2 to 4 days. Larger or more complex roofs (tile, steep pitch) can take a week or more.
Do I need to move out during installation?
No. You can stay home. Expect daytime noise and movement around the house, but we keep communication clear to avoid surprises.
Is my roof installation covered by a warranty?
Yes. Our workmanship warranty covers installation, and materials come with their manufacturer-backed coverage. We’ll explain both.
