Flat Roof

New York and the surrounding Tri-State area are both notorious for their flat roofs. Architecturally, it makes sense. But to water leaks, it seems more like a downhill battle.

Fortunately, the waterproofing industry has drastically changed this outlook – and we’re right there with it. Our cold-liquid application and fully reinforced waterproofing membrane are synonymous with safety and peace of mind. It’s hand-applied and can be fully effective within hours.

Our process


We’re ready when you are. Schedule your consultation for the date that works best for you. You won’t be waiting around for hours—our technicians will be on time and ready to inspect your property. As trained waterproofing professionals, they’ll assess current issues and detect potential damage before it happens. We also work with new construction projects for a build that lasts.


During the in-person inspection, our technicians will take measurements and gather any data they need to make an informed assessment. At this point, they can recommend initial solutions and offer experienced advice based on their evaluation. We’ll inform you of any potential repairs that may have to be done before the waterproofing process begins, and we’ll even let you know how long you can reasonably hold off. Why? We want you to feel in control of your options. Your satisfaction is our priority.


After our initial assessment, we’ll send over a comprehensive estimate. You can review it first and contact us later with any additional questions. When you’re ready, it’s time to pick out a date that works for you. We’ll watch out for weather conditions that might affect the application process and make suggestions. Our team will handle every aspect of the development phase, including mobilization and preparation. Our projects are always completed in a timely fashion at the highest level of quality.


Before we begin the project, we’ll prepare any surfaces and do the repairs as needed to eliminate unwanted issues which could potentially void the product’s limited warranty. At Liberty Waterproofing, inspection is the name of the game. We examine our work for quality at multiple checkpoints throughout the process. At the end of the construction phase, our team is committed to leaving a clean site—all debris is removed and properly disposed of. Our representative will take the time to walk you through your service warranty coverage.

Unlike sheet-applied membranes, liquid waterproofing does not require any heat, torches, or high temperature. It is cold liquid applied therefore it requires far less permits and does not create hazardous conditions.

Cold liquid applied waterproofing is fast, effective and safe! It takes far less time to apply the liquid (which also gives a seamless finish leaving no room for water penetration) compared to sheet-applied membranes.

Liquid applied waterproofing can be used on various surfaces, including flat roofs, terraces, green roofs, bathrooms, garages, pools, and basements.

The cost of liquid applied waterproofing varies due to several factors, including raw material costs, application time, cost of labor, and the type of material used.

The liquid membrane is cold applied by hand. Generally, it requires anywhere from 2 to 4 coats depending on the type of product we use.

Depending on the type of product, as well as the weather conditions it may take anywhere from 30 minutes up to 24 hours for the membrane to fully cure.

Yes! The waterproofing membrane is UV resistant. Also, most of our products can handle temperatures up to 482° F which makes them ideal for outdoor use.

Extreme high humidity, low as well as extreme high temperatures, are not ideal for application of a waterproofing membrane.

Liquid waterproofing can be easily applied to any flat surface and prevent it from being penetrated by moisture.
