At San Diego County Roofing & Solar, we believe in empowering our clients with knowledge. When it comes to commercial roofing, understanding the various components and systems is crucial. Here’s a detailed breakdown of the essential elements you should be familiar with:
Built-Up Roofing (BUR)
Built-Up Roofing, commonly referred to as BUR, stands as one of the time-tested and reliable roof systems. It primarily comprises three elements:
- Bitumen
- Ply sheets, usually made of fiberglass
- Gravel or a mineral cap sheet
Roof Coatings
These are monolithic, fluid-applied roofing membranes that adhere fully. Not only do they shield the existing roof system, but they also enhance the energy efficiency of the building.
The Role of a Cover Board
Positioned between the insulation board and the membrane material, a cover board imparts added durability to roof systems. It can be crafted from a range of materials.
EPDM Roof Systems
EPDM, or Ethylene Propylene Diene Monomer, is a single-ply rubber material favored for low-slope buildings. Its attachment can be adhesive, mechanical, or ballasted, and it boasts remarkable elongation and durability traits.
Inverted Roof Assembly
This unique design, often termed the ‘upside down’ roof, places the waterproofing layer beneath the thermal insulation. It’s an ideal choice for roofs that experience heavy traffic or are exposed to harsh weather conditions.
Mansard Roof Design
Mansard roofs merge the characteristics of gambrel roofs and hip roofs. Each side of this roof has two slopes, with one being steeper than its counterpart.
Modified Bitumen Explained
This system emerges when a polymer is introduced to asphalt. There are two primary types of modified bituminous materials, both of which can endure extreme temperature fluctuations and UV exposure.
Parapet Walls
Constructed at the roof’s edge, a parapet wall serves dual purposes: safeguarding the interior and ensuring the safety of individuals on the rooftop.
PVC Roofing
PVC, or Polyvinyl Chloride, is a single-ply system recognized for its versatility, chemical resistance, and waterproofing capabilities. Its seams are heat-welded.
The Foundation: Roof Deck
Supported by joists and trusses, the roofing deck bears the roofing material, snow loads, and construction traffic.
Roof Membrane
This waterproof covering system shields the roof deck and the building’s support structure.
Deciphering Roof Slope
The roof slope is the tilt of the roof, represented as the vertical rise’s ratio to the horizontal run, typically in inches per foot.
Single Ply Roofing System
Often termed elastomeric systems, these are sheets of flexible compounded plastic material designed to protect flat and low-sloped commercial structures. The popular types include TPO, PVC, and EPDM.
TPO Roofing
TPO, or Thermoplastic Polyolefin, is a single-ply system composed of a blend of polypropylene and ethylene propylene rubber components. Renowned for its UV resistance, TPO can be either mechanically attached or fully adhered.
