In regions like Pakistan and the broader MENA area, where intense heat and sunlight are common, applying heat proofing treatments to roofs is essential. These treatments help maintain comfortable indoor temperatures and reduce energy consumption. But a frequent question is: How long does a heat proofing treatment actually last? The answer depends on several factors such as the type of coating used, quality of application, and environmental conditions. Blogs
What Is Roof Heat Proofing?
Roof heat proofing involves applying special coatings or materials on the roof to reflect solar radiation and minimize heat absorption. This process helps keep indoor spaces cooler, reduces the load on air conditioning systems, and protects the roofing material from damage caused by prolonged exposure to heat and ultraviolet rays.
Typical Lifespan of Heat Proofing Treatments
The durability of heat proofing depends mainly on the type of material used:
Acrylic Coatings: These are budget-friendly and provide decent UV protection. Typically, acrylic coatings last between 5 to 10 years if maintained well.
Silicone Coatings: Known for excellent durability and water resistance, silicone coatings can last up to 20 years with proper care.
Polyurethane Coatings: Tough and resistant to wear, polyurethane coatings have a lifespan of around 10 to 15 years.
Elastomeric Coatings: These flexible coatings expand and contract with the roof, helping prevent cracks. They often last 10 to 15 years but can sometimes last as long as the building itself if well maintained.
Cork-Based Coatings: Eco-friendly with strong insulation properties, cork-based coatings can last up to 60 years.
