Professional Roof Waterproofing Solutions
Waterproofing adds a continuous protective layer that keeps water out of a roof, terrace, or balcony and protects everything beneath it.
What Is Roof Waterproofing?
Waterproofing is a system, not a single product. It combines surface preparation, careful detailing at seams and penetrations, and a coating or membrane that stays flexible as the roof moves. Done well on a roof that is still sound, it extends the life of the surface and reduces leaks caused by cracking and aging.
Where Roof Waterproofing Is Used
Our Roof Waterproofing Process
Assessment
We inspect the surface, seams, cracks, and drains, and check for hidden moisture.
System Selection
We decide with you whether a coating, reinforced membrane, or sheet system fits your surface.
Surface Preparation
We clean, repair damage, and prime the surface where the product requires it.
Detail Work
Seams, penetrations, edges, and drains are treated first, since these are where failures begin.
Application and Cure
We apply the system and protect it from rain and traffic during the required cure time.
Roof Waterproofing Methods and Materials
Waterproofing vs. Roof Replacement
Waterproofing Fits When
- The roof is sound but showing its age.
- The deck and structure are dry and solid.
- You want to extend the roof's life, not rebuild it.
Replacement Fits When
- The membrane or covering has already failed.
- Insulation or decking is saturated.
- Patches and coatings keep failing in the same spots.
Signs Your Roof May Need Waterproofing
- A chalky, cracked, or peeling surface. The coating has lost the flexibility it needs to keep water out.
- Hairline cracks across a flat roof or terrace that widen with every freeze.
- Open or lifting seams, where membranes fail first.
- Leaks around terrace doors and thresholds. A common point of failure at the deck-to-wall joint.
- A roof that is sound but tired. The best candidate for waterproofing, before real damage sets in.

Frequently Asked Questions
How long does roof waterproofing last?
It depends on the system, the surface, and exposure to sun and foot traffic. Most systems are rated for several years, and we will explain what to expect for your specific application.
Can waterproofing fix a roof that is already leaking?
Sometimes, if the underlying material is still sound. If the membrane or deck has already failed, waterproofing over it will not hold. We assess your roof first and tell you honestly which applies.
What does roof waterproofing cost?
Costs depend on the system, the surface condition, and how much detail work is needed at seams and penetrations. We provide a written estimate after assessing your roof.
Can I walk on a waterproofed terrace right away?
No. Most systems need a cure time before they can safely take foot traffic. We tell you exactly how long to stay off the surface.
Do I need to remove pavers or decking to waterproof a terrace?
Usually, yes. The waterproofing layer sits beneath the finish, so pavers, tiles, or decking generally need to be lifted and reset as part of the job.
Is waterproofing the same as roof coating?
A coating is one type of waterproofing. Waterproofing also includes reinforced membranes and sheet systems, and the right choice depends on your roof and how it is used.
