Seamless Liquid Rubber Solutions for Southwestern Ontario

Protecting your facility from the elements requires an advanced, commercial-grade approach. At Roofline Solutions, we specialize exclusively in high-performance, industrial and commercial flat roof waterproofing. Serving businesses across Southwestern Ontario, we provide a superior seamless liquid rubber system designed to eliminate leaks, extend the lifecycle of your existing infrastructure, and deliver unmatched weather resistance without the disruption or environmental waste of a full roof tear-off.

The Roofline Solutions Advantage

Traditional flat roofing systems rely on rolled membranes joined together by seams. Over time, fluctuating temperature shifts in Southwestern Ontario cause these seams to expand, contract, and ultimately fail, leading to costly leaks and structural moisture damage.

Our premium seamless liquid rubber system eliminates this vulnerability entirely. Applied directly over your existing stable roof substrate, it cures into a fully adhered, monolithic, and elastomeric barrier.

100% Seamless Protection: No joints, seams, or mechanical fasteners where water can penetrate.
Superior Chemical and UV Resistance: Formulated to withstand harsh industrial environments, intense UV exposure, and pooling water.
Exceptional Elasticity: Bridges minor cracks and moves dynamically with the building’s thermal expansion and contraction.
Cost-Saving Restoration: Eliminates the need for expensive, labor-intensive roof tear-offs by sealing and revitalizing your current roof structure.

Waterproofing creates a secure barrier that prevents leaks, water damage, and structural decay. By protecting the underlying structure, it significantly extends your roof’s lifespan and protects your property investment.

Local experts generally apply high-performance membrane coatings or liquid-applied sealants. We use a proven modern system called liquid rubber that is a superior waterproofing solution. The choice of material can be tailored specifically to your roof’s design and condition to ensure maximum durability.

No. Traditional materials like EPDM, TPO, or modified bitumen depend heavily on glued or welded seams, which represent the most common point of failure on a flat roof. Our liquid-applied system cures into a single, continuous rubberized sheet that blankets the entire roof, including complex penetrations, flashings, and HVAC curbs, eliminating seams entirely.

Yes. It’s actually best to patch current leaks and apply a waterproof seal at the same time for total protection.

Skipping proper surface cleaning, failing to address existing cracks, and mixing incompatible materials (such as using a water-based coating over oil-based substrates) are the most frequent errors.

Liquid rubber waterproofing on a flat roof typically lasts between 10 to 20 years. The longevity depends directly on the quality of the product applied, the thickness of the application, and the environment.
