Our Projects
San Francisco’s unique coastal climate and urban environment create specific challenges for commercial roofing systems. Understanding these common problems helps property owners recognize when professional commercial roof repair services are needed to prevent costly damage and business disruption.
Ponding water represents one of the most serious threats to commercial roofing systems in San Francisco, particularly on flat and low-slope roofs common in office buildings and warehouses. Standing water accelerates membrane deterioration, promotes organic growth, and can lead to structural damage if left unaddressed.
Causes of Ponding Water:
Our ponding water solutions address both immediate drainage issues and underlying structural causes. This comprehensive approach prevents recurring problems while protecting the roofing system from ongoing water exposure.
Ponding Water Repair Solutions:
Commercial roof membranes in San Francisco face constant threats from foot traffic, falling debris, HVAC maintenance activities, and wind-borne objects. Even small punctures can allow significant water infiltration, making prompt professional repair essential.
Common Puncture Sources:
Our puncture repair techniques vary based on membrane type, damage size, and location. Small punctures receive patch repairs using compatible materials, while larger damage may require membrane section replacement to ensure lasting protection.
HVAC equipment creates numerous roof penetrations that require proper flashing to prevent water intrusion. San Francisco’s thermal cycling and seismic activity can cause flashing systems to fail, creating leak points that threaten building integrity and equipment operation.
Critical Flashing Areas:
Professional flashing repair involves removing failed materials, preparing surfaces properly, and installing new flashing systems that accommodate building movement while maintaining weatherproof seals.
San Francisco’s daily temperature variations, often exceeding 30-40 degrees between morning fog and afternoon sun, create thermal shock that stresses commercial roofing materials. This constant expansion and contraction can cause membrane splitting, fastener backup, and seam failures.
Thermal Movement Effects:
Our thermal shock repairs address both immediate damage and system improvements that better accommodate thermal movement. This includes using flexible materials, proper expansion joints, and attachment methods that allow controlled movement.
San Francisco’s coastal location subjects commercial roofs to significant wind forces that can lift membranes, displace materials, and create entry points for water infiltration. Proper wind uplift resistance requires adequate attachment and edge detailing.
Wind Damage Indicators:
Wind uplift repairs often require system upgrades to meet current building codes, particularly on older buildings that may not comply with modern wind resistance standards.
California’s seismic activity affects commercial roofing systems through building movement that can cause membrane stress, flashing displacement, and structural separations. Proper seismic design accommodates expected movement while maintaining weatherproof integrity.
Seismic Damage Types:
Seismic-related repairs must consider ongoing building movement, using flexible materials and attachment methods that accommodate expected seismic activity while maintaining protective performance.
