Coatings & Restoration

Los Angeles & Orange County, CA : Commercial roof restoration (aka roof renovation) can be a smart alternative to a tear-off provided the flat or low-slope roof is a good candidate.

During the complimentary estimate, Central Roofing Company qualified estimators can determine if your existing roof is a prime candidate for a roof restoration service.

Part of our due diligence is to confirm with the city (where the building is located in) how many layers of roofing are allowed on your building. This would also apply to recovering a flat roof with a torch modified system.

If applicable, Central Roofing recommends a Silicone Roof Restoration because in our experience, it out performs and outlasts other roof coating alternatives. Silicone Systems, if properly applied, have a 20 year warranty and with proper care and maintenance can exceed that longevity.

Below are the types of roof systems we are currently certified and licensed to install for a commercial roof restoration, renovation or recover in Los Angeles and surrounding areas. All of these roof systems can meet Title-24 compliance.

Central Roofing Coating Restoration Steps

Roof Preparation

Not to be overlooked, roof preparation is the correction of roof issues prior to installation of the new coating system. This is a critical step to insure a quality installation that will maximize the useful life of the new roof.

Remove dirt, leaves, loose gravel at base flashing of parapet walls, foreign matters, debris, etc. from drains and waterways on an as needed basis.

DRAINS: Remove existing roof membrane and drain assembly as required. Clean and prime drain all metal. Install #28 base sheet and modified bitumen roof membrane. Reseal drain with white flashing grade or microfibers and silicone as required. Modified Bitumen, a twenty-year material, is a blend of atactic polypylene polymer mixed with high grade asphalt, reinforced with a non-woven polyester mat.

FIELD: Inspect field membrane for fractures, loose seams or blisters and repair with modified bitumen roof membrane, white flashing grade or microfibers and silicone as required.

PONDING: Supply and install modified bitumen roof membrane at severe ponding areas as required.

PIPES AND VENTS: Seal pipes and vents with flashing grade or microfibers and silicone as required.

Apply Emulsion & Polyester Reinforcement

The combination of applying layers of asphalt emulsion and polyester reinforcement forms a new, seamless, water-proof membrane over the existing roof and areas reinforced by Modified Bitumen.

COPING METAL: Resecure loose coping metal and refasten joints on an as need basis. Reseal joints with white flashing grade or microfibers and silicone as required.

HVAC/MECHNICAL EQUIPMENT/SKYLIGHT CURBS: Reseal A/C curbs with modified bitumen roofing membrane, flashing grade or microfibers and silicone as required.

PRESSURE WASHING: Pressure wash repair area prior to silicone topcoat application.

Apply White Elastomeric Top Coat

After 1 or 2 days of curing, the roof is ready for the white elastomeric top coat to be spray applied directly to the polyester reinforcement. After curing, you have an Energy-Star rated, Title-24 compliant Cool Roof that can dramatically reduce surface temperature and help reduce cooling costs.

Apply one coat of TROPICAL #918B PRIMER at the rate of approximately 1.0 - 1.5 gallons per 100 sq.ft. over entire roof surface.

Apply one coat of TROPICAL #924 ETERNA-SIL PREMIUM SILICONE ROOF COATING at the rate of approximately 2.0 gallons per 100 sq.ft. Tropical #924 Silicone Roof Coating (Energy Star approved, CRRC rated and California Title 24 compliant) is a high performance, solvent free, high solids, single component, moisture cure liquid applied silicone coating. Allow to cure.
