Green Living Roof Waterproofing

Green Roof installations start with waterproofing

Very few green roof manufacturers are also waterproofing experts. We not only provide the green roof products and optional service we also provide waterproofing with unmatched warranty’s.

Typical Warranty Includes:

  • Waterproofing = 20 years, No dollar limit, No slip sheet or protection fabric needed! Optional 10 year on top of the 20 year! All waterproofing is backed by GLTi strategic partners.
  • Vegetation = 2 year standard included with maintenance program installation + every year the client retains the maintenance program our Pro Staff will continue to warranty the vegetation.
  • Non-Vegetative Components = Standard 2 year upon installation + every year after with maintenance agreement.
  • Over Burden Removal = Included as part of the warranty and maintenance.
  • Periodic Preventative Waterproofing Inspection = Included as part of your maintenance program.

Amongst others, GLTi Green Roof Systems also support Tremco and Hyload, both industry-leading waterproofing membranes with the following benefits:


The AlphaGuard MT system is a single component, fully reinforced, aliphatic polyurethane, moisture-triggered roofing system composed of a base coat reinforced with a glass mat for durability and a top coat. Both coats are applied with rollers, minimizing the amount of equipment that will be on a building’s roof. The system carries FM Approvals RoofNav ratings, is UL fire-rated, complies with the Florida Building Code and meets ASTM 7311. The AlphaGuard MT can also be applied directly over OLD waterproofing!
