Industry-Leading Coating & Waterproofing Services
Spray Polyurethane Foam Cool Roof Systems
Spray Polyurethane Foam (SPF) roofing is one of the most efficient and cost-effective cool roof systems available. At DJM Coating Services, Inc., we apply Class- A fire-rated foam that expands into a seamless barrier, providing high thermal resistance and preventing leaks. It conforms to your existing roof, making it ideal for commercial and industrial buildings. SPF is lightweight, energy-efficient, and reduces your HVAC load.
GE Silicone Coating Systems
For roofs facing UV degradation, ponding water, or general wear, GE silicone roof coatings offer long-lasting protection. These coatings provide excellent adhesion and elasticity, even in extreme weather. They reduce heat absorption and extend the lifespan of your existing roof—often without the need for tear-off.

Waterproofing Deck Systems
Decks, walkways, and balconies take a beating from foot traffic and moisture. Our waterproofing systems protect these surfaces using flexible membranes that seal and resist cracking. Whether you need to waterproof a new deck or restore an aging surface, we build to perform and last.

Roofing Maintenance
Routine roof maintenance prevents small problems from turning into major expenses. DJM Coating Services, Inc. offers scheduled maintenance that includes:
- Power washing to remove buildup

that extend your roof’s life

Why It’s Important to Hire a Professional for Roofing & Coating Services
Waterproofing and roofing are not one-size-fits-all tasks. Improper application or low-quality materials can lead to water intrusion, mold, and structural damage. Hiring licensed, trained professionals like DJM Coating Services, Inc., ensures:
- Correct product selection for your environment
- Code-compliant installation
- Warranty protection
- Preventative insight based on decades of experience
DIY or low-cost alternatives often fail under pressure—literally and legally.
Why Coating & Waterproofing Services Matter
In California’s climate, temperature swings, rain, and UV exposure can quickly degrade roofing materials. Coating systems protect your investment while reducing long-term energy costs. A well-maintained roof improves insulation, enhances property value, and eliminates emergency repair bills.
For multi-family units, commercial facilities, and industrial buildings, timely coating and waterproofing avoid tenant complaints, business downtime, and liability.
