A Real Sunnyvale Story That Shows Why Licensing Matters
A 91-year-old Sunnyvale homeowner was nearly scammed out of ten thousand dollars by an unlicensed contractor demanding illegal deposits and “material fees.” Fortunately, his son noticed unusual bank activity, flew in from out of state, and stopped the withdrawal just in time.
Once the situation was uncovered, the son searched for a reputable, licensed roofing contractor in Sunnyvale and reached out to Home Pro Roofing and Solar. Our team stepped in, inspected the roof, corrected the unpermitted work, and installed a new roof to full California code.
This situation highlights a lesson every Bay Area homeowner should take seriously. When it comes to roofing, solar, and battery backup systems, choosing a licensed contractor is essential to protecting your home and your finances.
What CSLB Requires for Home Improvement Down Payments
California law is clear.
The down payment for residential work cannot exceed $1,000 or 10 percent of the contract price, whichever is less. No exceptions for “special-order materials.”
Unlicensed contractors often violate this rule, putting homeowners at major financial risk.
Why Hiring a Licensed Roofer Protects Bay Area Homeowners
In this Sunnyvale case, the unlicensed contractor cut corners that put the home at risk, violated building codes, and created safety issues that Home Pro had to correct. These are the most common red flags we find throughout Sunnyvale, Santa Clara, Palo Alto, and Mountain View.
1. No Building Permit Pulled
Roofing in California requires a building permit. It ensures compliance with city codes and supports future home resale value.
The unlicensed installer ignored this and began work without a permit, jeopardizing warranties and exposing the homeowner to legal problems.
2. No Tear-Off of the Existing Roof
Instead of removing old roofing materials, the installer shingled over the existing roof.
This hides wood rot, mold, and water damage. A licensed roofer always begins with a full tear-off so the new roof is built on a sound, inspected deck.
3. Roofing Over Old Shingles
A common shortcut among unlicensed contractors. It traps moisture, reduces lifespan, and can exceed load limits.
Licensed roofers in Sunnyvale, Mountain View, San Jose, and Palo Alto follow industry standards and local code, which prohibit this practice.
4. Mismatched, Incorrect Roofing Materials
The unlicensed contractor delivered mismatched shingles and incompatible materials.
This hurts curb appeal, decreases home value, and signals that the installer has no manufacturer training or certification.
Each of these failures shows how essential it is to work with a licensed roofer who follows local codes, pulls permits, and uses approved materials.
How Home Pro Roofing and Solar Corrected the Project
When Home Pro took over, we rebuilt the roof properly and installed a complete, code-compliant, energy-efficient system suited for future solar.
Full Tear-Off and Structural Inspection
We removed all the improperly installed materials, exposed the original wood shingle layer, and rebuilt the deck to modern standards.
Title 24 Energy-Efficient Roofing System
We installed the GAF Timberline Reflective Shingle Series, which helps Sunnyvale homes stay cooler and improves solar performance.
Premium Underlayment and Ventilation
Key components included:
- Tiger Paw underlayment for moisture protection
- Cobra ridge vents for attic airflow

These upgrades prepare the home for safe solar installation, Tesla Powerwall3 placement, and long-term energy performance.
Why Licensed Roofing Expertise Matters for Solar and Battery Systems
Many Bay Area homeowners combine roofing with solar panels or battery storage. A licensed roofing and solar contractor ensures:
- Correct roof load evaluation
- Flashing that prevents leaks around solar mounts
- Code-compliant battery placement
- Coordination with inspections and city requirements
Working with Home Pro — a licensed roofing and solar expert — ensures the entire project is done correctly from the start.

5-Star Review from the Homeowner’s Son
“I want to give Home Pro many kudos for the excellent roofing job they did on my 91-year-old father’s house. After chasing off a crooked roofing company that started the job, it was refreshing to have Russ Kahn come out and give us an estimate. The crew did an awesome job installing the roof and left the area around the house looking like it did before.”
