ACE provides third-party roof and waterproofing inspection in San Diego, California: substrate acceptance, membrane installation QA, ASTM D5957 flood testing, and Electronic Leak Detection. Our field reports build the warranty-grade documentation manufacturers require and owners need to enforce a claim years later. Every engagement is priced fixed-fee by scope — not by open-ended hourly rate.
Roof and waterproofing systems are single-line-of-defense assemblies — one failure point compromises everything below. Third-party inspection at critical milestones (substrate acceptance, membrane installation, penetration flashing, post-installation testing) creates the QA record owners need for warranty enforcement and defect defense. We inspect low-slope roofs, plaza decks, split-slabs, below-grade waterproofing, and traffic-bearing coatings.

San Diego sits in a Mediterranean (Zone 3B Warm-Dry / 3C Warm-Marine) climate zone. Long dry summers with intense UV loading, punctuated by concentrated winter rain events, produce a fatigue cycle that ages sealants faster than a temperate-zone envelope. Coastal exposures add salt-aerosol driven corrosion; inland exposures add thermal-cycling stress. Both push toward higher-grade fluoropolymer and silicone systems. The San Diego building stock we most often work in includes coastal salt-fog exposure, downtown high-rises, and North County mixed-use podiums. San Diego low-slope roof failures we most commonly document are penetration flashing terminations, drain-bowl sealant, and TPO seam separation at reinforced-fabric transitions. See California building envelope coverage for the multi-market context, and Envelope Testing — San Diego for a complementary scope in the same market.
Roof inspections examine terminations first — parapet flashings, drain sumps, mechanical penetrations — because that’s where 80% of failures start.
Covering San Diego roof moisture survey and related scopes
Slope, drainage, penetrations, and substrate compatibility documented before the membrane goes down — because once it does, the record is gone.
Continuous inspection of seams, terminations, flashings, penetrations, and cure conditions per manufacturer specification.
Low-voltage or high-voltage EFVM/ELD survey of installed membrane to identify breaches before final overburden or roofing components are installed.
ASTM D5957 24-hour flood test on plaza decks and split-slabs with photographed pass/fail record.
Field reports meeting manufacturer warranty documentation standards — the record the owner needs for a future warranty claim.
Every engagement follows a three-phase delivery structure so you know what you are getting, when.
Annual inspection is best practice everywhere; on San Diego projects with severe UV, freeze-thaw, or salt exposure we often recommend a formal semi-annual walk in addition to the annual full inspection.
ELD/EFVM applies a controlled voltage across the membrane. Because water conducts, any breach in the membrane appears as a low-resistance path. On plaza decks and green roofs where the overburden is expensive to remove, ELD identifies breaches while they are still trivial to repair.
Best practice is a post-installation inspection, an annual walk during years one through five, and a pre-warranty-expiration inspection at year nine or ten. On San Diego projects with continuous freeze-thaw or extreme UV exposure we sometimes recommend semi-annual inspection.
Third-party inspection is quoted by inspection-day count, roof area, and complexity. A typical medium-scale commercial re-roof scopes substrate acceptance, three-to-five installation-inspection days, and post-installation Electronic Leak Detection — fixed-fee inclusive.
Yes. Post-installation ELD is a common stand-alone engagement, especially on plaza decks and green roofs where the overburden is expensive to remove if a breach is found later. Priced fixed-fee by roof area.
ACE Building Envelope Design has practiced envelope engineering across the Western United States on hundreds of commercial, multifamily, institutional, and legal-defense projects. Our senior engineers are licensed Professional Engineers, active in FGIA and ASTM committees, and have provided expert testimony in state and federal envelope-defect matters.
