Your roof is the first line of defence against the elements. To keep it well-maintained and protected, a high-quality membrane is essential. This protective layer helps to shield your home from water damage, preventing costly repairs and extending your roof’s lifespan.
But with different roof materials and various membrane options available, how do you choose the right one? This guide will walk you through matching the best membrane to your specific roof type.
Understanding Common Roof Types and Their Needs
Different roofing materials have unique characteristics that influence the type of coating they require.
-
- Tile Roofs: Tile roofs are durable but can be porous. The gaps between tiles are vulnerable to water entry, especially in heavy rain. A flexible membrane is crucial to seal these gaps and cover the tile surface without cracking.
- Metal Roofs: Metal roofing is popular for its longevity. However, it is prone to expansion and contraction with temperature changes. This movement can stress seams and fasteners, creating potential leak points. A flexible, adhesive membrane that can move with the metal is necessary.
- Terracotta Roofs: Terracotta tiles are renowned for their durability, natural insulation, and timeless aesthetic appeal. Made from fired clay, they resist UV damage, extreme heat, and harsh weather conditions. Their curved profile helps channel rainwater efficiently, while their thermal properties keep homes cooler in hot climates. When installed with proper underlayment, terracotta roofs can last 50 years or more, making them a sustainable and long-term roofing solution.
Exploring Your Membrane Options
Roofing membranes come in several materials, but Globalcote’s specialty acrylic exterior coatings—Elastacote and Infracote—are purpose-built for Australia’s climate. These coatings deliver durability, UV resistance, and long-term protection while being environmentally friendly and easy to apply.
Globalcote’s Liquid-Applied Acrylic Membranes
-
- Elastacote: A water-based 100% acrylic coating designed to restore and protect roofs. It provides a seamless finish that seals porous surfaces, resists UV damage, and flexes with natural roof movement.
- Infracote: An infrared-reflective acrylic coating that reduces heat absorption, improving energy efficiency while protecting against harsh weather conditions.
Matching the Right Membrane to Your Roof
-
- Tile Roofs Elastacote or Infracote creates a seamless protective layer that seals porous tiles, fills fine gaps, and flexes with roof movement. Their UV resistance ensures colour fastness and long-term durability.
- Metal Roofs Infracote is especially effective for metal roofs. Its infrared-reflective technology reduces heat absorption, while its seamless bond prevents leaks at seams and fasteners.
- Terracotta Roofs Elastacote and Infracote preserve the natural beauty of terracotta while sealing against moisture ingress. They enhance colour retention, inhibit moss and lichen growth, and extend roof lifespan.
The Primecote Sealer/Primer is a key part of the Globalcote Roof Membrane System, designed to seal and prime surfaces for stronger adhesion and longer-lasting top coats. Made from 100% acrylic, it’s water-based for easy application and clean-up, and proudly Australian made and owned.
Available in tailored options, Primecote suits a variety of surfaces: Standard for tile and metal roofs, High Build for very porous tiles, Terracotta for unglazed or glazed terracotta, Metal with rust inhibitor for treated metal surfaces, and Facade for exterior walls.
By choosing the right option, you ensure maximum coverage, durability, and performance of Globalcote’s roof membranes.
Tips for Proper Installation
Proper installation is just as important as choosing the right material.
-
- Prepare the Surface: The roof must be thoroughly cleaned of dirt, debris, and any moss or lichen. A product like Prepcote Surface Treatment can inhibit future growth.
- Prime for Adhesion: Use a high-quality primer, such as Primecote Sealer/Primer, to ensure the membrane bonds securely to the roof surface.
- Follow Manufacturer Instructions: Every membrane has specific application guidelines. Adhering to these is crucial for performance and warranty coverage.
- Hire a Professional: For the best results, consider hiring a professional painter or roofer. Experts have the right tools and experience to ensure a flawless application.
