Damp patches on ceilings, peeling paint after rainfall, or standing water on the roof are signs that should not be ignored. Even in buildings where leakage has not yet appeared, waterproofing can be installed as a preventive measure to protect the roof before water reaches the internal layers and finishes.
We provide professional waterproofing services for homes, villas, buildings, and facilities across Saudi Arabia, starting with a roof inspection to assess its condition and identify potential sources of water ingress, followed by selecting the appropriate waterproofing system, preparing the site, installing the required layers, and inspecting the completed work before handover.
With more than 11 years of experience in insulation and waterproofing works, we approach each project according to its actual condition. Membrane rolls or liquid-applied systems are not selected simply because they are available; the choice is based on the roof type, exposure to water, and specific project requirements.

When Do You Need Waterproofing?
Waterproofing may be required as a preventive measure before a problem occurs or as a corrective solution after signs of water ingress have appeared.
Some of the main situations that require a roof inspection include:
- Rainwater leaking into the building.
- Water remaining on the roof for extended periods.
- Damp patches appearing on ceilings or walls.
- Peeling paint or damaged finishes caused by moisture or water ingress.
- A new roof that needs protection before the remaining finishes are completed.
- An existing waterproofing layer that needs to be assessed before relying on it.
In these situations, we do not immediately install a new waterproofing layer. We first identify the source of the problem and assess the roof condition to avoid covering an existing defect with a new system without addressing the underlying issue.
Where Is Waterproofing Used?
The installation method varies according to the element being protected and the way it is exposed to water.
Waterproofing can be used on concrete roofs exposed to rainfall and standing water. Suitable systems may also be used on certain metal roofs when the product specifications permit this application.
Other areas, such as bathrooms or water tanks, may require waterproofing systems specifically designed for their intended use, site conditions, and technical requirements.
A material that performs successfully on a concrete roof is therefore not automatically suitable for every other waterproofing application.
Roof Inspection Before Waterproofing Installation
The inspection is the first practical step because it determines whether the problem is related to the existing waterproofing layer or whether the roof requires other corrective work before a new system can be installed.
During the inspection, we assess the roof condition, visible leakage areas, cracks, issues that may affect the system, areas of standing water, drainage outlets, and floor-to-wall junctions.
Existing waterproofing layers are also inspected where present, as installing a new system over unstable layers can affect the quality and durability of the work.
Once these factors have been assessed, the required preparation, waterproofing material, and application method can be determined instead of making a decision based solely on the visible appearance of the leak.

How Do We Select the Right Waterproofing System for a Roof?
The system is selected after assessing the roof type, exposure to water, existing condition, project requirements, and the technical specifications and approvals of the product being considered.
Depending on the project, suitable systems may include:
Bituminous Waterproofing Membranes
Bituminous membrane rolls can be used in applications for which they are suitable. Installation follows the system requirements for surface preparation, primer application, membrane placement, overlaps, and details around drains and corners.
Liquid-Applied Waterproofing Systems
Liquid-applied waterproofing systems can be used on suitable projects to form a protective layer after the material has been properly applied and cured according to the manufacturer’s instructions.
The appropriate liquid system depends on the roof characteristics, exposure conditions, and intended use.
Flexible Waterproofing Membranes
Flexible membranes can be used when their properties and technical specifications meet the requirements of the project. Surface preparation, application method, thickness, and number of layers must follow the requirements of the selected system.
Materials such as bitumen, acrylic-based products, or cementitious systems may be used in different waterproofing applications. However, a material is not selected simply because of its name; it must be suitable for the site and meet the required technical specifications.
When selecting materials, we also consider relevant technical requirements in the Saudi market, including applicable regulations and specifications for insulation and waterproofing materials issued by the relevant authorities, such as the Saudi Standards, Metrology and Quality Organization.
Roof Waterproofing Installation Process
Once the appropriate system has been selected, installation follows a clear sequence because the quality of the final waterproofing layer depends heavily on the work completed before it is applied.
1. Roof Inspection
Leakage areas, cracks, and existing issues are identified while the overall condition of the roof and its readiness for the work are assessed.
2. Roof Cleaning
Dust, debris, concrete protrusions, and any materials that could affect adhesion or continuity of the waterproofing system are removed.
3. Repairing Existing Defects
Issues that form part of the surface preparation requirements are addressed to ensure that the roof is suitable for the selected system before application begins.
4. Checking Roof Slopes and Drainage
Water flow, areas of ponding, drainage outlets, corners, and floor-to-wall junctions are inspected because these details are important when installing roof waterproofing.
5. Applying Primer When Required
If the selected system requires a primer, the appropriate product is applied and the manufacturer’s drying and application requirements are followed before proceeding to the next stage.
6. Installing the Waterproofing Layers
Membrane rolls or the approved waterproofing system are installed according to their specifications, with particular attention to overlaps, corners, drainage outlets, and other details that affect the continuity of the waterproofing layer.
7. Inspecting the Waterproofing Before Covering
The completed waterproofing layer is inspected for continuity, and any observations are addressed before protective layers or finishes are installed over it.
8. Water Testing When Appropriate
When water testing is suitable for the selected system and site conditions, it is carried out using the appropriate procedure before the work is approved and the following stages begin.
Why Do Roof Slopes and Drainage Matter Before Waterproofing?
The purpose of waterproofing is to reduce water penetration, but it does not eliminate the need for proper drainage design.
Low areas that retain water or problems with drainage outlets can cause water to remain on the roof for extended periods. For this reason, roof slopes and drainage points are reviewed before the waterproofing system is approved.
The objective is not simply to cover the roof with a waterproof material, but to install the system over a suitable base that allows it to perform according to the project design.
An inspection may show that water ingress is not caused by the protective layer alone and that the roof first requires a broader assessment of its overall condition, existing layers, or multiple details affecting how the project should proceed. In this situation, we do not install a new system directly over the existing condition. Instead, the project is referred to Roof Insulation so the roof can be evaluated as a complete system and the required work can be properly sequenced before installation continues.
Waterproofing for Concrete Roofs
Concrete roofs require careful inspection before waterproofing is installed, particularly when cracks or areas with previous leakage are present.
Once the concrete has been properly prepared, the system suitable for the project is installed, with particular attention to drains, edges, corners, and roof penetrations.
The waterproofing layer is inspected before protective layers are installed over it so that any area requiring additional work or treatment is not hidden.

What If the Inspection Reveals Concrete Cracks That Require Specialized Repair?
Not every crack is simply a surface defect that can be hidden beneath a waterproofing layer.
If the inspection identifies concrete cracks that require specialized treatment before the waterproofing system can be completed, their condition is assessed first rather than using waterproofing as a substitute for treating the underlying issue.
When this type of intervention is confirmed to be necessary, the project is referred to Concrete Injection for the appropriate repair. The waterproofing system can then be completed according to the roof condition after treatment.
Waterproofing for Metal and Sheet-Metal Roofs
Metal roofs have different characteristics from concrete roofs, so the same waterproofing system is not automatically applied to both.
The condition of the metal sheets, joints, fixings, and areas around openings is inspected before selecting a product approved for the intended application and compatible with the metal substrate.
This is important because adhesion, movement of the roof surface, and exposure to weather conditions all affect system selection.
What If the Project Requires Protection Against Both Water and Heat?
Sometimes the problem is not limited to water leakage. The roof may also experience significant heat gain, and the client may want both requirements addressed as part of an integrated approach.
In this situation, we do not turn the waterproofing service into a thermal insulation system. Instead, the second requirement is assessed separately, and the roof build-up is designed so the different layers can work together without conflict.
If the project genuinely requires reduced heat transfer in addition to water protection, you can proceed to our Thermal Insulation service to determine the appropriate system for that part of the project.
When Is Polyurea Recommended?
Polyurea is not the default choice for every roof and is not recommended simply because a different waterproofing layer is being considered.
When project conditions require a high-performance membrane and the system properties are suitable for the roof and intended use, its suitability is assessed according to the technical specifications and preparation and application requirements.
If the assessment confirms that this system is appropriate for the project, you can proceed to our Polyurea Waterproofing service to review its installation requirements separately.
Testing the Waterproofing Before Completing the Finishes
Inspection after installation is an essential stage before the waterproofing layer is covered.
The continuity of the system and the completed details are reviewed to ensure that no areas remain unfinished. When the system and site conditions allow, an appropriate water test may be carried out to verify the work before protective layers or finishes are completed.
A single testing method is not used as a fixed procedure for every system because the appropriate verification method depends on the waterproofing type, application instructions, and project conditions.
What Does Properly Installed Waterproofing Achieve?
A suitable waterproofing system helps limit water penetration into the protected elements and reduces damage associated with moisture and leakage.
The intended results include:
- Protecting the roof against rainwater penetration according to the system’s performance characteristics.
- Reducing moisture penetration into interior finishes.
- Protecting paint and other areas affected by leakage.
- Reducing the need for repeated repairs caused by water damage when the system is correctly installed and maintained.
- Providing a solution suited to concrete or metal roofs when the appropriate product is used.
Waterproofing Company in Riyadh
We provide waterproofing services in Riyadh for homes, villas, buildings, and facilities that require protection against rainwater and ponding or need an existing waterproofing system assessed because it is no longer performing as required.
Our service in Riyadh begins with a roof inspection to assess leakage areas, cracks, slopes, and drainage outlets. The appropriate material, preparation method, and installation process are then determined according to the project condition.
Whether the project involves protecting a new roof before finishing or treating a roof where signs of moisture have already appeared, the scope of work is determined first to avoid installing a new waterproofing layer over an unresolved problem.
If the inspection shows that the source of leakage is related to a water tank rather than the building roof, the treatment method, materials, and post-installation testing requirements will be different. In this situation, the project is referred to Water Tank Waterproofing in Riyadh to inspect the tank structure, cracks, and joints, select the appropriate waterproofing system, and test the tank before returning it to service.

Quality and Warranty for Waterproofing Works
The warranty is determined according to the waterproofing system, materials used, roof condition, and agreed scope of work, ensuring that warranty terms relate directly to the system actually installed.
The selected material, preparation requirements, and main system layers are also explained to the client before installation begins, while taking into account the manufacturer’s instructions and relevant technical specifications for the project.
This approach allows the client to make a decision based on the actual work to be carried out rather than general promises that are unrelated to site conditions.
Frequently Asked Questions About Waterproofing
What Is the Best Waterproofing System for Roofs?
There is no single product that is best for every roof. The appropriate system is selected according to the roof type, water exposure conditions, intended use, project requirements, and technical specifications.
Can New Waterproofing Be Installed Over an Existing Waterproofing Layer?
This decision should not be made before an inspection. The existing layer must be assessed for condition, adhesion, and compatibility with the new system. Some projects may require partial removal or treatment before installation.
Are Bituminous Membranes Better Than Liquid Waterproofing?
Each system has different applications and requirements. The choice between bituminous membrane rolls and liquid-applied waterproofing depends on the roof characteristics, project details, and required specifications rather than one system being universally better than the other.
Can a Roof Be Waterproofed After a Leak Appears?
Yes, waterproofing can be installed after leakage occurs, but the source of the leak must first be identified and any defects requiring treatment should be addressed before the new system is installed.
Is Waterproofing Tested After Installation?
When water testing is appropriate for the selected system and site conditions, it may be carried out before protective layers or finishes are completed, together with direct inspection of the waterproofing layer.
Can Waterproofing Be Used on Metal Sheet Roofs?
Some waterproofing systems can be used on metal roofs when they are approved and suitable for this application. The appropriate system is selected after inspecting the metal sheets, joints, and overall roof condition.
How Long Does Waterproofing Installation Take?
The duration depends on the project area, roof condition, selected system, amount of preparation required, and drying or curing time of the materials used. A more accurate timeframe is determined after the inspection.
Do You Provide Waterproofing Services Outside Riyadh?
Yes. Subject to the coverage of our installation teams, we provide services in Riyadh, the Eastern Province, Jeddah, Al Qassim, and Hail, while also accepting requests from Makkah, Madinah, Taif, and other areas depending on project accessibility.
