BUILDING ENVELOPE & WATERPROOFING

The Roof Stops at the Edge. The Building Envelope Doesn't.

A roof replacement that ignores compromised facade, failed window sealants, or missing air barriers will leak again within years. AOD manages the full weather barrier — roofing first, then the envelope systems that complete the picture.

  • Waterproofing Systems

    Plaza decks, below-grade walls, parking structures, mechanical pits, and foundation walls. Sheet-applied and liquid-applied membrane systems. Critical companion to roofing on complex facility types where roof-to-wall transitions are primary infiltration sources.

  • Facade & Exterior Wall Restoration

    Masonry repointing, concrete repair, EIFS remediation, and exterior coating systems. Specified when building envelope survey reveals wall-to-roof transitions and deteriorated masonry are contributing to infiltration the roof alone cannot solve.

  • Window Glazing & Curtain Wall

    Sealant replacement, reglazing, curtain wall water infiltration remediation, and frame repair. Window failure is among the most common sources of interior moisture damage in facilities undergoing roof replacement.

  • Air/Vapor Barriers

    Continuous air barrier installation and repair. Energy code compliance under ASHRAE 90.1 and UFC energy standards. Coordinated with roofing scope to ensure continuous protection through the wall assembly.

  • Joint Sealants & Penetration Seals

    Building expansion joints, penetration seals, perimeter sealant replacement, and transition seals. AOD includes sealant survey in every RAMP™ assessment — sealant failure is the most overlooked source of building infiltration
