When it comes to roofing, choosing the right material isn't just about aesthetics or durability; it's also about performance in varying weather conditions and maintenance requirements. High-top roofs, also known as box gutters or flat roofs with parapet walls, present unique challenges and opportunities. They require specialist knowledge to install and maintain, making reviews and ratings a crucial factor in deciding on a professional roofer.
With high-top roofing, safety, waterproofing, and durability are paramount. The roof must withstand heavy rain, wind, and snow, while also providing a barrier against heat gain in summer. Therefore, it's essential to assess the materials, methods, and warranties offered by roofing companies specializing in high-top roofs. But where do you start? Here, we explore two key aspects of high-top roofing: materials and installation methods, providing practical insights from real customers' experiences.
Materials for High-Top Roofing
Choosing the right material for your high-top roof is the first step towards a durable, long-lasting roof. Here, we delve into two popular options: EPDM rubber membrane and built-up roofing (BUR) membranes.
EPDM Rubber Membrane
EPDM, or ethylene propylene diene monomer, is a synthetic rubber roofing membrane. Its wide application in high-top roofs is due to its excellent flexibility, durability, and resistance to both heat and cold. EPDM roofs can last up to 50 years with proper maintenance, offering a long-term solution for property owners.
Elite Commercial Roofing, a leading roofing contractor, swears by EPDM, citing its "superior durability and flexibility, making it an excellent choice for high-top roofs." They also highlight EPDM's energy-efficient properties, which can lead to significant savings on heating and cooling costs.
Built-Up Roofing (BUR) Membranes
BUR membranes consist of multiple layers (or plies) of bitumen and reinforcements. The bitumen can be hot-mopped or cold-applied, providing excellent durability and resistance to punctures and tears. BUR systems are often used in high-traffic or heavy foot-traffic areas, making them suitable for high-top roofs with regular maintenance access.
GenFlex, a manufacturer of BUR membranes, notes that their products "deliver superior performance and durability," making them an ideal choice for high-top roofs. They also emphasize the customizability of BUR systems, allowing architects and builders to create unique, aesthetically pleasing roofs that complement various building designs.
Installation Methods for High-Top Roofing
The installation method significantly impacts the lifespan and performance of your high-top roof. Understanding the two primary methods – fully-adhered and mechanically-attached – will help you make an informed decision.
Fully-Adhered Installation
Fully-adhered installation involves bonding the membrane directly to the substrate using a cold or hot adhesive. This method provides excellent wind uplift resistance and can be applied to various substrates, including wood, metal, and concrete. However, it requires a clean, dry surface and can be labor-intensive.
Thermafleece, a supplier of high-performance insulation, recommends the fully-adhered method for high-top roofs, as it "seals the membrane to the substrate, creating a monolithic, self-healing barrier that can bridge minor substrate movement."
Mechanically-Attached Installation
Mechanically-attached installation involves attaching the membrane to the substrate using fasteners. This method allows for easier future inspections and re-roofing, as the membrane can be easily peeled back. However, it may have lower wind uplift resistance compared to fully-adhered systems.
FRS Roofing, a roofing contractor specializing in high-top roofs, praises the mechanically-attached method for its "quick and easy installation, making it an ideal choice for re-roofing or new construction projects with tight deadlines."
In the world of high-top roofing, selecting the right material and installation method can make a significant difference in the lifespan and performance of your roof. By understanding the unique benefits and drawbacks of EPDM, BUR, fully-adhered, and mechanically-attached systems, you're well-equipped to make an informed decision. Remember to consult with professional roofers, review customer testimonials, and request warranties to ensure you're getting the best possible high-top roof for your property.
