$1.50–$5+
per sq ft typical 2026 installed range for professional acrylic/silicone waterproof roof coatings in Santa Monica / Westside LA
SCAQMD, City Permits & Coastal Zone
SCAQMD Rule 1113 VOC limits apply. Painting and similar finish work, including many exterior coatings, is often exempt from building permit. Re-roof or structural changes may require City of Santa Monica approval; Coastal Zone properties should verify CDP status for any work beyond routine maintenance.
Salt Air, High UV & Marine Moisture
Coastal exposure accelerates ordinary coating failure. Silicone systems resist ponding and long-term UV; acrylics deliver reflectivity and cost-effective restoration on well-drained surfaces. Flexible elastomeric coatings accommodate building movement and salt-laden air.
One License, Multi-Scope Advantage
CSLB #1083764 covers General Building (B) and Painting & Decorating (C-33). Waterproof coatings, surface restoration, and exterior finishes stay under one contractor.
Commercial, Multi-Family & Coastal Stock
Downtown and Pico corridor commercial roofs, multi-family and HOA properties, and buildings near the ocean that demand salt- and UV-resistant systems. Deck, balcony, and roof waterproofing are high-volume applications.
Our Process
Assessment & Substrate Evaluation
On-site inspection of roof, deck, or wall condition—moisture, existing coating adhesion, ponding, salt exposure, penetrations, and flashings. Coastal Zone and permit status flagged early if relevant.
System Selection & Spec
Recommendation of acrylic, silicone, elastomeric, or hybrid waterproof coating based on slope, drainage, UV and salt exposure, occupancy, and warranty goals. SCAQMD-compliant, coastal-suitable products specified.
Surface Preparation
Pressure washing, removal of failed material, seam and penetration reinforcement, crack bridging, and primer. Thorough prep is critical in salt-air environments.
Application & Quality Control
Spray, roller, or squeegee application to manufacturer mil thickness. Multiple coats as required. Weather and temperature windows observed for correct cure under marine-layer conditions.
Walkthrough & Documentation
Final inspection, thickness verification where applicable, and warranty paperwork. Pasadena HQ supports ongoing maintenance recommendations for Westside properties.
Pasadena headquarters provides reliable project management and consistent site presence for Santa Monica and Westside jobs, with efficient coordination for commercial and multi-family clients.
Do waterproof coatings need to be SCAQMD compliant in Santa Monica?
Yes. Santa Monica is within the South Coast Air Quality Management District. Rule 1113 sets VOC limits for architectural coatings—roof coatings typically 50 g/L, many waterproofing sealers and membranes 100 g/L or lower. Only compliant products may be applied. We specify and install Rule 1113-compliant systems.

Is a building permit required for waterproof coatings in Santa Monica?
Painting, papering, and similar finish work—including color or texture coating of exterior plaster—is generally exempt from building permit under Santa Monica Municipal Code. Pure coating maintenance on existing sound roofs or walls often falls in this category. Re-roof, structural repairs, or membrane replacement may require a building permit from City of Santa Monica Building & Safety. We confirm requirements during assessment.

Does coastal zone status affect waterproof coating projects?
Routine maintenance and like-for-like exterior coatings typically do not trigger a Coastal Development Permit. Development that alters structural footprint, increases height, or changes intensity of use can require CDP review. We flag Coastal Zone status early and coordinate any needed approvals.

How do acrylic and silicone waterproof coatings perform in Santa Monica’s coastal climate?
Acrylic systems are cost-effective, highly reflective (cool-roof benefit), and perform well on roofs that drain properly. Silicone systems resist permanent ponding water and offer superior long-term UV and salt-air stability—especially valuable on coastal flat roofs. Flexible elastomeric wall coatings accommodate movement and resist wind-driven moisture.

“Our commercial roof near the Pico corridor needed a waterproof coating that could handle coastal UV and occasional ponding. El Lay applied a silicone system—clean process, SCAQMD-compliant, and the building stayed fully operational.”
Facility Manager, commercial property
Downtown / Pico corridor
“Multi-family deck waterproofing in Ocean Park was phased around residents with almost no disruption. The elastomeric system stopped the leaks and has held up under the salt air.”

“Elastomeric coating on our coastal multi-family elevations solved the moisture issues and refreshed the appearance. One contractor handled prep and coating under their multi-scope license.”

Professionally installed waterproof roof coatings in Santa Monica and the Westside typically range $1.50–$5+ per square foot depending on chemistry (acrylic vs silicone), substrate condition, access, and required preparation. Acrylic systems often fall $1.50–$4.00/sq ft; silicone $2.00–$5.00+/sq ft. Deck and specialized membrane systems run higher. These are planning ranges—final pricing is based on on-site inspection and scope.
Yes. We hold California CSLB License #1083764 for General Building (B) and Painting & Decorating (C-33). We are licensed, bonded, and insured and perform waterproof coating work throughout Santa Monica and the Westside.
Yes. Santa Monica is in the South Coast Air Basin. SCAQMD Rule 1113 sets VOC limits for architectural coatings. Roof coatings are generally limited to 50 g/L; many waterproofing categories are limited to 100 g/L or lower. We only specify and apply compliant products.
When the existing substrate is structurally sound and free of widespread moisture damage, a high-quality acrylic or silicone coating restoration can extend service life 10–20 years at roughly 40–60% of the cost of full replacement. We evaluate moisture, insulation, and adhesion before recommending coating versus replacement.
Acrylic coatings are typically lower cost, highly reflective (cool-roof benefit), and perform best on roofs that drain well. Silicone coatings resist permanent ponding water and offer excellent long-term UV and salt-air stability—especially valuable under Santa Monica’s coastal exposure.
Our headquarters is at 1055 E Colorado Blvd, Pasadena, CA 91106. Santa Monica and the Westside are regular service markets for us, with consistent project management and reliable site presence supported from the Pasadena office.
Yes. We apply elastomeric waterproof coatings to exterior walls, walking decks, balconies, and other building-envelope surfaces in addition to roof systems—especially relevant for multi-family and HOA properties in Santa Monica’s coastal climate.
Most commercial roof coating projects of moderate size can be completed in a few days to two weeks once preparation is finished, depending on weather windows (including marine-layer conditions) and cure times. Larger multi-building or multi-elevation projects are typically phased around occupancy.
