Membrane systems and liquid-applied coatings that seal your roof against water intrusion at parapets, penetrations, and low-slope drainage areas.
Bakersfield Expert Roofing offers professional roof waterproofing in Bakersfield, CA with over 20 years of experience handling residential and commercial roofing projects.
Standard roofing materials handle direct rainfall effectively, but vulnerable transition points like parapets, pipe penetrations, HVAC curbs, and skylight frames require additional waterproofing to prevent slow moisture migration. We install sheet membrane systems, liquid-applied polyurethane and silicone coatings, and targeted sealant treatments designed to withstand thermal cycling across Kern County's temperature range. Each system is selected based on roof type, slope, and the specific failure points identified during our pre-installation survey.
Seamless liquid coatings form a monolithic waterproof barrier with no seams or joints where water can penetrate. We apply silicone and polyurethane coatings at manufacturer-specified mil thickness, verified with wet film gauges during installation. These coatings bond directly to existing substrates including TPO, EPDM, modified bitumen, and metal.
STEP 1
We survey the entire roof surface to identify current and potential water entry points, including failed sealants, ponding areas, membrane blisters, and deteriorated flashing transitions. Moisture meter readings confirm whether subsurface damage already exists.
STEP 2
All surfaces are cleaned, dried, and primed per coating manufacturer specifications. Existing failed sealants and blistered membrane sections are removed and patched before the waterproofing system is applied to ensure proper adhesion.
STEP 3
Waterproofing materials are applied at specified thickness using wet film gauges for quality control. Seams and transitions receive reinforcing fabric where required. After curing, we conduct a flood test or controlled water application to verify watertight performance.
Pipe boots, HVAC curbs, skylight frames, and parapet walls are the most common points of water entry on commercial and flat residential roofs. We reinforce each penetration with compatible membrane wraps and sealant collars that accommodate thermal movement without cracking or delaminating.
Wet film gauge verification during application ensures coating thickness meets manufacturer specifications at every point.
Flood testing after installation confirms watertight performance before the job is signed off.
Compatible with all major commercial roofing substrates including TPO, EPDM, modified bitumen, and standing seam metal.
Targeted penetration sealing addresses the most common failure points on flat and low-slope roofs in the Kern County area.
Low-slope sections, parapets, penetrations, and transition zones are high-priority areas where added waterproofing protection can prevent recurring leaks.
No. Waterproofing improves moisture defense for qualifying roofs, while full replacement is recommended when overall system condition is beyond repair.
Service life depends on substrate condition, product type, sun exposure, and maintenance. We recommend periodic inspection to preserve performance.
