All You Need To Know About Commercial Roofing Systems

Introduction

Roofs come in different styles for homes and big buildings. Home roofs usually have a slant and use things like tiles or shingles. But big building roofs, known as commercial roofing, are flatter and not as noticeable. They use special materials because they face different weather challenges. Exploring commercial roofing is like discovering how they work quietly to protect big buildings. It's not just about having a roof; it's about understanding how each one does its job.

The Evolution Of Commercial Roofing Materials And Modern Technology

Commercial roofing contractors in Nashville stay updated on the latest developments in commercial roofing technology and possess expertise in recommending the most suitable roofing solutions for specific projects. In recent times, there have been introductions of innovative commercial roofing materials designed to offer exceptional resistance to temperature extremes while optimizing environmental efficiency. These advancements aid in minimizing stormwater runoff and cutting down on heating and cooling costs.

Configurations Of Commercial Roofs

When it comes to commercial roofing systems, understanding the shape of the roof is crucial. Commercial roofs typically fall into two categories: Low Slope Roofs (or Flat Roofs) and Steep Slope Roofs.

Low Slope Roofs

These roofing systems are prevalent in warehouses, big box stores, and shopping centers. Characterized by a gentle incline, low slope roofs offer various flat roof options such as EPDM, PVC, and TPO for effective protection against the elements.

Steep Slope Roofs

In contrast, steep slope roofs are more commonly found on single and multi-family homes than on commercial properties. Recognizable by their steeper angles, these roofs often feature materials like metal, shingles, slate, or tile. Each material is chosen for its durability and aesthetic appeal, contributing to the overall character of the structure.

Types Of Commercial Roofing System

Once you've determined the slope of your roof, the next step is selecting the ideal roofing system to cater to your business needs. Here, we outline the most prevalent commercial roofing systems.

Single-Ply Membranes

Single-ply membranes, a common choice for commercial roofing, include materials like TPO, PVC, and EPDM. Thermoplastic Olefin (TPO) is renowned for its energy efficiency and reflective properties, providing resistance against UV rays and chemicals.

PVC (Polyvinyl Chloride) stands out for its durability and excellent waterproofing capabilities, making it adept at withstanding harsh weather conditions and chemical exposure.

Ethylene Propylene Diene Monomer (EPDM), a synthetic rubber membrane, is highly durable and flexible. Its resistance to ozone and UV radiation makes it suitable for various climates. The single-ply membrane category offers diverse options to cater to different roofing needs.

Built-Up Roofing (BUR)

Built-Up Roofing (BUR) involves layering bitumen (asphalt or coal tar) with reinforcing fabrics, creating a robust roofing system. This method allows for customization, as the number of layers can be adjusted based on specific building requirements. BUR systems provide superior waterproofing and durability, making them suitable for structures where long-term performance is crucial. This traditional yet effective approach to commercial roofing ensures resilience against various weather conditions.

Metal Roofing

Metal roofing stands out as a versatile choice, offering options such as steel, aluminum, and copper. Renowned for their strength and durability, steel roofs can withstand extreme weather conditions. Coatings are frequently applied to prevent corrosion, ensuring a prolonged lifespan.

Aluminum roofing, on the other hand, is lightweight and corrosion-resistant, making it ideal for coastal areas. Its low maintenance requirements and recyclability further contribute to its environmental appeal. Copper roofs, prized for their aesthetic appeal, not only offer excellent durability but also develop a unique patina over time, adding to their visual charm.

Additionally, it's worth noting that metal roofing can be installed over shingles, but it is recommended to consult with your roofing contractor to ensure compatibility and adherence to best practices.

Modified Bitumen

Modified bitumen roofing combines asphalt with modifiers like APP or SBS, resulting in enhanced flexibility, strength, and resistance to temperature fluctuations. APP-modified bitumen offers improved UV resistance, while SBS-modified bitumen provides greater flexibility, making it suitable for buildings with high foot traffic or those in areas prone to temperature extremes. Modified bitumen roofing systems offer a balance of durability and adaptability, making them a popular choice in various commercial settings.

Liquid Applied Roofing Membranes

Constructed on-site using resin and a reinforcing polyester, a liquid applied roofing membrane stands out for its exceptional waterproofing capabilities, effectively reaching challenging areas. Typically applied in two separate coats through spraying or rolling, this liquid roof ensures a thorough and resilient seal.

The unique application method of a liquid roof minimizes disturbances and eliminates the emission of strong or harmful odors. This characteristic makes it an excellent choice, particularly for businesses that need to remain open during construction. For such applications, a reputable commercial roofing company can provide expert installation and ensure a seamless roofing solution without causing disruptions.

Coated Roofs

Comprising a fluid-applied membrane, this fully adhered coating exhibits remarkable flexibility, capable of stretching and returning to its original shape. Roof coatings come in various types, with acrylic and silicone being the most prevalent. Specifically designed for metal roofs, these coatings play a pivotal role in cooling buildings, minimizing energy consumption, safeguarding against leaks, and prolonging the lifespan of commercial roofs. Regular application of such coatings is a proactive approach to commercial roof maintenance, ensuring lasting durability and performance.

Green Roofs'

While not universally suitable, green roofs offer manifold benefits where applicable. Beyond their natural insulation, they reduce energy costs, provide pleasant spaces for people and animals, and manage stormwater, potentially reducing the reliance on complex drainage systems.

The installation of green or vegetative roofing systems underscores the commitment of Roofing Company in Nashville to enhancing spaces and environmental well-being.

PVC Commercial Roofing System

Photovoltaic (PV) solar panels, integrated into PVC (Polyvinyl Chloride) commercial roofing systems, capture natural sunlight and convert it into usable energy. Particularly advantageous in sun-rich regions, these panels present an opportunity for long-term cost savings.

Commercial roofers not only facilitates the installation of rooftop PV systems but also ensures the roofing system's integrity, keeping buildings watertight without disrupting PV system operations.

Steep Slope Roofing

Steep slope roofing, typically associated with residential properties, occasionally graces commercial buildings for aesthetic reasons. Seen in structures like hotels or universities, it involves slopes of 3:12 or higher.

Commercial roofing in Nashville recognizes the diversity in roofing materials for steep slopes, ranging from asphalt composition rolls to wood shakes, clay, concrete tile, slate, and metal.

Elevating Efficiency With Insulation & Cover Boards

Cover boards and thermal insulation play a pivotal role in boosting a roof's energy efficiency, resulting in lower utility bills. Nashville Roofing Company understands the opportune moment to enhance insulation and meet contemporary energy codes is during roof replacement, ensuring a seamless integration of efficiency measures into your building.

Installation Techniques For Commercial Roofings

The installation of a commercial roofing system is a complex process that requires skilled professionals. Depending on the chosen material, installation techniques may vary. Some common methods include:

• Mechanically Attached Systems: Fasteners and screws are used to secure the roofing material to the structure.

• Fully Adhered Systems: Adhesives are used to bond the roofing material directly to the roof substrate.

• Ballasted Systems: Large stones or pavers hold the roofing material in place, providing stability and protection against wind uplift.
  

Best Maintenance Practices

Regular maintenance is crucial for the longevity and performance of a commercial roofing system. Maintenance practices may include:

• Inspections: Regular inspections to identify and address issues before they escalate.

• Cleaning: Removal of debris and ensuring proper drainage to prevent water pooling.

• Repairs: Prompt repair of any damage, including leaks, punctures, or loose materials.

Energy Efficiency And Sustainability

Modern commercial roofing systems often prioritize energy efficiency and sustainability. Cool roofing materials with high solar reflectance can help reduce energy consumption by reflecting more sunlight and absorbing less heat. Additionally, some roofing materials are recyclable, contributing to a more sustainable building environment.

Common Issues And Repairs:

Commercial roofs are susceptible to various issues such as leaks, membrane damage, and ponding water. Timely identification and repair of these issues are crucial to prevent extensive damage and costly repairs.

Roof Replacement Considerations

Eventually, every commercial roof will reach the end of its lifespan. Understanding when it's time for a replacement and choosing the right materials for the new roof are essential decisions for property owners.
