Waterproofing contractors for concrete roofs in Toronto - Waterproofing Service Toronto

Waterproofing Service Toronto provides professional waterproofing for concrete roofs of residential and office buildings both in Toronto and the GTA. Our professional contractors make use of an advanced waterproofing system to protect your concrete roof from rainwater and moisture, thus protecting it from long-term structural damage and keeping you safe and leak-free throughout the year.

Why Waterproofing Concrete Roofs is Essential

Concrete is inherently porous, and over time it will absorb water from:

Cracks and leaks in roofing surfaces

Mold and mildew growth

Weakening of the roof structure

Paint peeling and damp patches

Costly structural repairs

That is why waterproofing of concrete roofs is not just maintenance; it’s a long-term investment in the safety and durability of your building.

Our Concrete Roof Waterproofing Services

We provide top-quality waterproofing services for each type of roof and building in Toronto.

1. Roof Inspection & Leak Detection

Our team does a detailed roof survey to identify all cracks, water entry points, and weak spots before commencing with the waterproofing process.

2. Surface Cleaning & Preparation

We clean the roof surface for dust, oil, and other debris to achieve a perfect adhesion of the waterproofing membrane or coating.

3. Application of Waterproof Coating

We apply liquid-applied waterproof membranes or cementitious coatings that will give your concrete roof a seamless, durable, and UV-resistant layer.

4. Crack Sealing & Joint Treatment

We seal all cracks, joints, and gaps using polyurethane and epoxy sealants in order to prevent further water infiltration into the structure.

5. Improved Roof Drainage

Our contractors ensure that there is a proper slope of the roofs and good drainage systems to avoid the ponding of water for an extended life of the roof.
