Core Waterproofing & Protection Capabilities
Roof Waterproofing
Holistic moisture-barrier engineering protecting sloped, flat, and low-slope residential and commercial properties against driven rain and standing water.
Flat Roof Waterproofing
Heat-welded 60-mil TPO, cold-applied elastomeric rubber, and heavy-duty EPDM single-ply installations engineered to resist continuous ponding water.
Terrace Waterproofing
Multi-layer polyurethane traffic coatings designed for outdoor balconies, rooftop patios, and living decks beneath concrete pavers or exterior tile.
Concrete Roof Waterproofing
Penetrating crystalline treatments and crack-bridging elastomeric membranes that seal concrete pores against water absorption and steel rebar corrosion.
Liquid Roof Waterproofing
Cold-applied high-solids silicone and liquid polyurethane that cure into a seamless, monolithic rubber blanket without a single failure-prone seam.
Waterproof Roof Coating
Bright-white 100% silicone restoration coatings that reflect 85% of solar UV radiation while permanently sealing aged flat roofs against water intrusion.
Our 6-Step Waterproofing Application Process
- Step 1 — Substrate Mechanical Cleaning & Moisture Testing: We power-wash and mechanically scrape the surface down to solid substrate, removing dirt, laitance, oil, and failed coatings.
- Step 2 — Crack V-Grooving & Expansion Joint Pre-Treatment: All structural fissures and expansion seams are opened with diamond blades, cleaned, and packed with backer rods and polyurethane mastic.
- Step 3 — Penetrating Epoxy / Hydrophobic Primer Coat: We roll a high-tack primer across the deck to promote permanent chemical adhesion between the roof deck and the waterproofing membrane.
- Step 4 — Polyester Scrim Fabric Embedding at Critical Junctions: Woven polyester reinforcement fabric is fully embedded into wet basecoats around all 90-degree parapet transitions, HVAC curbs, and scuppers.
- Step 5 — Primary Elastomeric / Membrane Application (Multi-Pass): We apply the primary waterproofing system in two cross-hatched coats to achieve specified dry-film thickness (minimum 30 to 45 mils).
- Step 6 — 48-Hour Electronic Leak Detection or Static Water Flood Test: On flat roofs and terraces, drains are temporarily plugged and the surface is flooded with 2 inches of water for 48 hours to physically verify zero moisture penetration.

Frequently Asked Questions
1. How much does professional roof waterproofing cost in Cary, NC?
Roof waterproofing in Cary typically costs between $2.50 and $6.50 per square foot for liquid-applied elastomeric or silicone roof coatings, and between $5.00 and $11.00 per square foot for heavy-duty multi-layer sheet membranes.
2. What is the difference between Liquid Roof Waterproofing and Sheet Membrane Waterproofing?
Liquid waterproofing cures into a monolithic, seamless rubber skin that has zero seams — ideal for roofs with dozens of pipes and HVAC units. Sheet membrane waterproofing comes in prefabricated rolls.
3. How long do waterproof roof coatings and polyurethane membranes last in North Carolina?
High-solids silicone and polyurethane waterproofing systems installed to manufacturer thickness typically last 15 to 20 years in Wake County.
4. Can you waterproof a concrete terrace or outdoor balcony without tearing up existing tiles?
In many cases, yes. If the existing tile and mortar substrate is structurally sound, we can apply transparent or tinted aliphatic polyurethane liquid membranes directly over the tiles.
5. Why is ponding water so dangerous for flat roofs, and how does waterproofing solve it?
Ponding water exerts tremendous weight on roof trusses. Modern 100% silicone waterproofing coatings are completely chemically impervious to ponding water.
6. Can a waterproof reflective roof coating lower summer energy bills in Cary, NC?
Yes! Bright white 'Cool Roof' silicone coatings reflect up to 85% of solar heat back into the atmosphere, lowering air conditioning cooling expenses by 15% to 25%.
7. How do you seal active roof leaks and expansion joints during heavy rain?
During severe rainstorms, our emergency technicians use moisture-curing hydrophilic polyurethane mastics that react chemically with water to form an instant seal.
8. Is roof waterproofing covered by manufacturer warranties in Cary, NC?
Yes, our commercial and residential roof waterproofing installations come with 10, 15, and 20-year leak-free material and workmanship warranties.
