When it comes to property maintenance, the roof often gets overlooked—until it starts leaking. Over time, even the most well-constructed roofs age and become vulnerable to cracks, seepage, and structural damage. That’s why old roof waterproofing is not just a smart choice—it’s essential.
In Pakistan, especially in cities with extreme weather conditions like Karachi, Lahore, and Islamabad, old roofs are under constant threat from heat, rain, pollution, and humidity. Fortunately, companies like Lakhwa Chemical Services offer expert waterproofing solutions designed specifically to restore and protect aging roofs.
In this blog, we’ll explore why old roof waterproofing is critical, the techniques involved, and how Lakhwa Chemical Services can help extend your roof’s life and protect your property.
Why Old Roofs Need Waterproofing
1. Age and Wear
As roofs age, their materials deteriorate. Concrete loses its density, tiles may crack, and joints begin to loosen. Without waterproofing, water starts to seep in, causing:
-
Damp spots on ceilings and walls
-
Mold and mildew growth
-
Structural weakening
Water damage often goes unnoticed until it’s too late—and expensive to fix.

2. Climate and Rainfall
Pakistan’s monsoon season can dump heavy rain in a short period. Older roofs often lack the resilience to withstand prolonged exposure to moisture. Waterproofing provides a protective barrier that shields your home or building from rain damage.
3. Rising Energy Bills
Old, porous roofs let heat in during summers and trap moisture during winters. Waterproofing can also act as insulation, helping regulate indoor temperatures and reduce your energy bills.
Signs Your Roof Needs Waterproofing
Not sure if your roof needs attention? Look for these warning signs:
-
Visible cracks or hairline fractures in the surface
-
Water stains or bubbling paint on ceilings
-
Persistent leaks, even minor ones
-
Unusual odors due to mold growth
-
Peeling or blistered surface coatings
-
Past 10 years without maintenance
If you notice any of these, it’s time to take action before the damage escalates.
What Is Roof Waterproofing?
Roof waterproofing involves applying a protective layer or chemical treatment to prevent water from penetrating the surface. For older roofs, waterproofing does more than just block moisture—it restores integrity and prolongs lifespan.
Different methods are used depending on the condition and material of the roof. That’s why working with an expert like Lakhwa Chemical Services is key—they inspect, recommend, and apply the most suitable solution for your specific needs.
Methods Used for Old Roof Waterproofing
Lakhwa Chemical Services uses a variety of advanced waterproofing techniques tailored to old structures:
1. Bitumen Membrane Waterproofing
Bitumen sheets are torch-applied over the roof surface, forming a seamless water-resistant layer. These are ideal for flat or slightly sloped roofs and offer excellent durability.
2. Cementitious Waterproofing
A mix of cement-based compounds is applied to cracked or worn-out surfaces. This is commonly used for roofs with severe wear and tear, offering a cost-effective restoration solution.
3. Polyurethane (PU) Coating
PU is a liquid-applied waterproof membrane that fills cracks and cures into a durable, elastic barrier. It adapts to surface irregularities, making it ideal for older, uneven roofs.
4. Acrylic-Based Coatings
Environmentally friendly and UV resistant, acrylic coatings provide both waterproofing and heat-reflective properties. This is a popular choice for clients also looking to reduce heat inside the building.
5. Crack Filling and Joint Sealing
Before any waterproofing is done, all visible cracks and expansion joints are sealed with high-grade sealants to prevent future water ingress.
