Waterproofing

Stop Water Intrusion at the Source

Water follows the path of least resistance. Legacy Roofing finds the weak points in your building envelope—cracks, failed sealants, and worn joints—and installs the right system to keep water out and your building protected.

Where Water Gets In

  • Hairline cracks & porous masonry
  • Failed window, jamb & transition sealants
  • Slab joints and deck penetrations
  • Worn surfaces on ramps & walkways
  • Aged balcony & stair coatings

How We Address It

  • Elastomeric wall coatings
  • Joint sealants at windows & transitions
  • Air & water barrier membranes
  • Traffic-bearing membrane systems for decks
  • Crack repair & slip-resistant coatings

Building Envelope & Parking Structures

We waterproof both the building envelope and the parking decks, ramps, and walkways around it—reducing interior damage, improving safety, and helping you avoid premature repairs.
