There are many roofing systems for commercial flat roofs - Hot Mop Roofing, Modified Bitumen Roofing, and Single Ply are among the main systems we use in Southern California.
Hot Mop roofing, also known as Built-Up Roofing (BUR), has been a cornerstone in the roofing industry for decades. This traditional method involves layering hot asphalt and roofing felt to create a robust and seamless roofing system.
The Advantages of Hot Mop roofing systems include:
- Proven durability: Hot Mop roofing is renowned for its enduring strength, with a history of reliable performance. Multiple layers of bitumen and roofing felt create a sturdy and resilient roofing system that can withstand punctures, tears and various weather conditions.
- Waterproofing excellence: the application of hot asphalt ensures seamless and watertight surface, offering superior waterproofing
- Adaptability: suitable for roofs with complect shapes, making it a versatile choice for various architectural designs
Modified Bitumen roofing is an evolution of traditional BUR and incorporates polymer-modified asphalt sheets or rolls. These sheets come in two main types: SBS (Styrene-Butadiene-Styrene) and APP (Atactic Polypropylene). SBS offers increased flexibility, while APP provides greater resistance to UV exposure.
Modified bitumen roofing is installed using a variety of methods, including heat welding, cold adhesives, or self-adhesive sheets. This provides flexibility in installation methods.
The advantages of Modified Bitumen roofing include:
- Durability: Modified bitumen roofing is known for its durability and ability to withstand harsh weather conditions. It provides a long-lasting roofing solution that can endure temperature extremes, UV exposure, and other environmental factors.
- Flexibility: The addition of polymers, such as SBS (Styrene-Butadiene-Styrene) or APP (Atactic Polypropylene), enhances the flexibility of the bitumen. This flexibility allows the roofing material to adapt to temperature changes without cracking, making it suitable for varying climates.
- Waterproofing: Modified bitumen roofing provides effective waterproofing for low-slope roofs. The seams are sealed during installation, creating a watertight barrier that helps prevent water infiltration and protects the underlying structure.
Single Ply roofing includes materials like TPO (Thermoplastic Olefin), PVC (Polyvinyl Chloride), and EPDM (Ethylene Propylene Diene Monomer).
Advantages of Single Ply roofing system include
- Lightweight and Easy Installation: Single Ply systems, including TPO, PVC, and EPDM, are generally lightweight, contributing to ease of installation.
- Reflectivity: TPO and PVC can be highly reflective, enhancing energy efficiency and reducing cooling costs.
- Chemical Resistance: Single Ply membranes, such as TPO and PVC, exhibit resistance to chemicals and pollutants.
