Commercial Waterproofing Challenges.

Commercial buildings present waterproofing challenges that residential properties do not. Rooftop equipment creates multiple penetration points that must be sealed precisely. Enterprise internet equipment, HVAC curbs, exhaust vents, fire alarm systems, security devices and skylights all require individual attention to prevent water entry.

Large roof areas increase the risk of ponding water, which accelerates membrane deterioration and creates additional leak opportunities. San Francisco's daily temperature swings between morning fog and afternoon sun stress flashings and sealants through constant expansion and contraction.

Sure Roofing addresses these commercial-specific demands with systems suited for equipment-heavy roofs and installation methods that prioritize long-term sealing performance.

Waterproofing Around Rooftop Equipment.

Sure Roofing seals penetrations around HVAC systems, fire alarm equipment and security devices without disrupting building operations or damaging sensitive components. Every penetration point is addressed individually, and crews coordinate work around your building's schedule.

Sure Roofing's detail-oriented approach includes:

  • Sure Roofing precisely seals around HVAC curbs, condensate lines and refrigerant piping to prevent water entry at these common penetration points.

  • Sure Roofing carefully seals fire alarm system penetrations and conduit entries as part of every commercial waterproofing project.

  • Sure Roofing protects rooftop equipment from debris and damage throughout each project.

  • Crew scheduling at Sure Roofing is coordinated with building operations to minimize disruption to your business.

Penetration points around rooftop equipment are among the most common sources of commercial roof leaks. Proper flashing and sealing at these locations is critical to long-term roof performance.
