Roof leakage can become a serious building problem when rainwater repeatedly enters through cracks, joints, damaged coatings and unsealed roof openings. What starts as a small damp patch can eventually affect ceilings, plaster, paint and other interior finishes.
Roof Waterproofing in Kohat helps protect residential, commercial, agricultural and industrial roofs against water penetration. The right waterproofing solution depends on the roof surface, existing damage, drainage system and required level of protection.
Unicorn Chemical provides Roof Waterproofing Services according to the condition and requirements of each project. Proper inspection and surface preparation are important before waterproofing materials are applied.
Why Roofs in Kohat Need Proper Protection
A concrete roof can develop cracks as the structure ages or experiences movement. Joints between different sections can also become weak and allow water to enter.
Leakage may occur around parapet walls, roof edges, drainage outlets, pipe openings and water tank bases. Blocked drains can increase the problem because water remains on the roof for longer periods.
Old waterproofing can also deteriorate. Cracked or loose coatings may need repair or removal before a new waterproofing system is installed.
Waterproofing Solutions for Different Roof Conditions
There is no single waterproofing system that works for every building. The material should be selected according to the roof condition and project requirements.
PU Waterproofing
PU waterproofing can create a flexible and seamless protective layer. It can be considered for roofs where continuous coverage and flexibility are important.
Liquid Membrane
Liquid membrane systems are applied over prepared surfaces and can provide continuous protection around corners, edges and detailed roof sections.
Torch On Bitumen Membrane
Torch on bitumen membrane uses waterproof sheets installed over a prepared roof. Proper overlaps and detailing around joints and edges are important.
Cementitious Waterproofing
Cementitious waterproofing can be suitable for selected concrete surfaces. The roof needs proper cleaning and preparation before application.
Crack and Joint Treatment
Cracks and joints should be assessed before the main waterproofing system is installed. Repair requirements depend on the size, depth and location of the damaged section.
Roof Waterproofing Price in Kohat
The Roof Waterproofing Price depends on roof size, material selection, surface condition and preparation requirements.
| Waterproofing System | Indicative Price |
|---|---|
| Cementitious Waterproofing | PKR 150 to 350 per sq ft |
| PU or Liquid Membrane | PKR 200 to 450 per sq ft |
| Torch On Bitumen Membrane | PKR 180 to 400 per sq ft |
| Large Commercial or Industrial Roof | Custom quotation |
| Roof Crack Repair | Site inspection required |
For a 1000 sq ft roof, indicative planning costs may be around PKR 150000 to 350000 for cementitious waterproofing, PKR 200000 to 450000 for PU or liquid membrane and PKR 180000 to 400000 for torch on bitumen membrane.
These figures are indicative planning ranges rather than fixed quotations. The final Roof Waterproofing Cost can change when extensive crack repair, old coating removal, drainage correction or additional surface preparation is required.

Home Roof Leakage and Moisture Problems
Residential roofs often have water tanks, bathrooms, pipes and drainage outlets that create several potential leakage points.
A visible ceiling stain may not be directly underneath the actual roof defect. Water can move through concrete before appearing inside a room.
For this reason, a professional Waterproofing Contractor should inspect the complete roof and identify vulnerable areas before deciding whether localized repair or full waterproofing is appropriate.
Commercial Buildings and Business Properties
Shops, offices, schools and other commercial buildings can have larger roof surfaces with multiple drainage points and service installations.
A proper waterproofing assessment should examine the complete roof rather than treating only the location where water is visible.
Roof edges, joints, corners, drains and pipe penetrations should be checked as part of the preparation process. The quotation should also clearly explain the material, preparation work and application scope.
Agriculture and Storage Structures
Agriculture and horticulture are among the economic sectors identified for Kohat while the district also has mining, hydrocarbon extraction and manufacturing activity.
Farm buildings, storage areas and warehouses can have wide roof surfaces that need protection against rainwater.
For these structures, drainage is particularly important. Water outlets should remain clear and the roof should be checked for areas where water collects after rainfall.
Industrial Roof Protection
Kohat has established activity in mining, hydrocarbon extraction and manufacturing. The district profile identifies limestone and gypsum mining as important sectors and also notes cement and textile manufacturing.
Industrial buildings may have machinery, service pipes, ventilation equipment and other installations on their roofs. These features can create additional points that require careful waterproofing.
For a large factory or warehouse, the assessment should consider the complete roof surface, drainage layout, joints, penetrations and existing coating.
Steps Before Applying Waterproofing
A waterproofing project normally starts with an inspection of the roof. Visible cracks, loose material, old coatings, standing water and drainage problems are identified.
The surface is then cleaned and prepared. Loose or deteriorated material may need to be removed before repair work starts.
Cracks and joints are treated according to their condition. Special attention should be given to parapet walls, roof edges, corners, drainage outlets, pipe penetrations and water tank bases.
Once preparation is complete, the selected waterproofing system is applied over the required area. The completed surface should be checked for gaps and incomplete coverage.
Warning Signs That Should Not Be Ignored
Consider arranging a roof inspection if you notice:
- Damp ceiling patches
- Water stains after rainfall
- Peeling interior paint
- Visible roof cracks
- Standing rainwater
- Leakage around water tanks
- Moisture near pipe openings
- Damaged old waterproofing
- Recurring leakage after temporary repairs
Early inspection can help locate the cause of water entry before continued moisture creates more extensive damage.
Finding the Right Waterproofing Contractor
When choosing a Roof Waterproofing Company, avoid comparing contractors only by the lowest quoted price.
Ask what waterproofing system will be used and whether the quotation includes surface cleaning, preparation, crack treatment and waterproofing layers.
It is also useful to understand how the contractor plans to treat drainage outlets, roof edges, joints and pipe penetrations.
A search for a Waterproofing Company Near Me can help locate service providers but the proposed system and complete scope of work should still be reviewed before the project begins.
Maintaining Roof Protection After Treatment
Waterproofing should be followed by regular roof maintenance. Drainage outlets should be kept clear so rainwater can move away from the surface.
Avoid unnecessary drilling through waterproofed areas. If new equipment or pipes are installed later, affected sections should be sealed properly.
After heavy rainfall, check areas where water tends to collect. Small defects can often be addressed before they develop into larger leakage problems.
Regular inspection can help preserve long term Roof Protection.
