HomeWhich is the Best Waterproofing Solution for an Old House Roof?
Sep 25, 2024
As a home grows rich in memories, its structure grows old too. Over this passing time, homeowners try their best to ensure the longevity and safety of their homes. Yet its walls bear marks of who lived inside and its roof gathers evidence of the time it has endured.
In India, roofs are continuously exposed to harsh sunlight, torrential rains, and chilly winters. This relentless exposure can lead to the development of cracks and fissures. While the environmental factors themselves are not a direct threat, the resultant cracks can compromise the structural integrity of the roof, posing a risk to the safety of the inhabitants.
Given this scenario, roof waterproofing becomes essential, especially for older roofs, as it protects against water infiltration, which can lead to serious damage over time.
Before we give away the best waterproofing solution that is suitable for old roof leakage repair, let’s explore all our waterproof roof coatings for roof leakage repair solutions.
Different Liquid Waterproofing Membranes by Type of Coating Materials
- Cementitious Waterproofing Coating
Let’s get this one out of the way almost immediately. While it is the most commonly available solution—and relatively the lowest possible cost you can incur in the range of waterproofing solutions—the negligent stretchability of cement forces one to reapply once every few years. - Bituminous Waterproofing Coating
Versatile in its compatibility with different surface types, bituminous coatings offer excellent waterproofing properties when applied to rooftops and terraces. The application, although, could get messy unless you seek professional assistance and/or undertake proper safety precautions. - Epoxy Waterproofing Coatings When the durability of the roof is of extreme importance, the hard enduring surfaces created by Epoxy coatings are loved by all. The limited flexibility of resultant protective barriers is compensated by the strong adhesive properties of the coating. The process, unless administered by a professional, can get pretty complicated for someone new to it.
- Acrylic Waterproofing Coatings
Water-based and environment-friendly, acrylic coatings offer a flexibility that is greater than some counterparts and a good degree of UV resistance. The water base of the coating makes acrylic coatings best for regions with mild weather conditions. - Polyurethane Waterproofing Coating
Extremely durable, excellently flexible, smart crack-bridging capabilities, and quite resistant to weathering over time—some would say that Polyurethane Waterproofing solutions are the best waterproofing solutions out there whether you have to waterproof old or new roofs.
What Makes Polyurethane Waterproofing the Most Efficient for Repairing Old Roofs?
Selecting the appropriate liquid waterproofing membrane depends on the specific requirements of the roof, including flexibility, durability, environmental exposure, and budget. While the initial investment might be higher for Polyurethane roof waterproofing, it is one of the best solutions for repairing old roofs in particular for a host of other reasons.
