TPO roofing is a relatively new addition to the roofing materials market, with about 33 years in existence. Still, it has already gained a reputation for its performance, especially on flat roofs.

Composition and Features

TPO is a single-ply three-layered membrane composed of a TPO polymer base, a polyester-reinforced scrim, and a TPO compounded top ply. Thermoplastic, in layman’s terms, means it becomes plastic when heated and hardens upon cooling.

TPO roofing offers superior stability and resistance to shrinking compared to EPDM, another popular thermoplastic membrane roofing material. An EPDM membrane can alligator, while TPO is less likely to shrink over time, resulting in a long-lasting, reliable system.

Furthermore, TPO roofing provides significant energy cost savings due to its highly reflective properties, which deflect the sun’s UV rays away from the building, keeping the interior cooler and reducing energy consumption.

Note: Geographic regions higher in altitude with high UV levels adversely affect the TPO and are often the number one problem TPO systems face in these regions.

Types of TPO Roofing Membranes and Their Thickness

TPO roofing membrane is typically sold in 45 mil, 60 mil, and 90 mil thicknesses, which is about the thickness of a heavy-duty trash bag. A thicker roof membrane should be considered for roofs that experience higher traffic (i.e., walkways or technicians routinely servicing rooftop units).

Two primary types of thermoplastic membrane roofing exist: Polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO). TPO membranes have three layers, making them a highly durable and efficient choice for commercial buildings.

The TPO single-ply roofing membrane has gained popularity due to its energy advantages and durability. With its ability to resist heat and most UV rays, TPO roofing is an eco-friendly option that can yield significant energy savings for building owners.

TPO Roofing Installation Process

Following the specified installation process for TPO roofing is crucial to its performance and longevity. A high-level overview of installing TPO involves preparing the roof surface and substrate, choosing the proper insulation and thickness, attaching the membrane, and using a hot-air gun to weld the seams.

The heat-welded seams create a watertight seal that prevents leaks and protects your building’s interior. Hiring an experienced contractor to install TPO roofing is highly recommended due to the specialized tools and expertise required for a successful installation.

The layers of a complete, fully adhered TPO roofing system are as follows:

1. TPO membrane
2. Bonding adhesive (if fully adhered)
3. Cover board (recommended on roofs with regular foot traffic)
4. Insulation
5. Vapor barrier (optional, but roofs over concrete decking should always have a vapor barrier)
6. Underlayment (typically installed when an improved fire-resistive rating is required)
7. Roof decking

Preparing the Roof Surface

Before installing a TPO roof, the existing substrate must be appropriately prepared to ensure a successful installation. This involves cleaning, repairing, and priming the substrate to create an even surface for optimal adhesion. A flat surface is essential during installation to ensure proper adhesion of the TPO membrane and prevent water damage.

Priming the substrate is a crucial step in the installation process. It involves applying a primer to the substrate, ensuring optimal adhesion. Once the surface is prepared, and the insulation foam is installed, the TPO membrane can be attached securely to the roof deck, providing a durable and energy-efficient roofing system.

Insulation and Mechanical vs Adhered Attachment Methods

Insulation sheet foam is the component that dictates energy efficiency and must be installed to guarantee a satisfactory level of heating and cooling efficiency within the property. Several insulation options are available for TPO roofing, such as foam board or batt insulation. The type of insulation selected depends on the existing roof type, necessary insulation levels, as well as the specific needs of your building.

The TPO membrane can be mechanically attached using fasteners or attached using a fully adhered adhesive system. In mechanically fastened systems, the membrane is attached in the seams using fasteners and plates or battens. Fully adhered systems are completely bonded to the substrate beneath, creating a tighter and more secure looking TPO membrane. The bonding adhesives can’t be applied below certain temperatures. However, the adhesive in fully adhered systems evenly distributes the uplift pressure on the membrane and substrate, rather than focusing it on fastening points in the seams as the mechanically attached method does. This is why fully adhered systems typically have superior wind uplift results. Conversely, mechanically attached systems are often more cost-effective and have fewer installation restrictions. Each method offers advantages and is chosen based on factors such as the building’s structure, climate, and budget.

Regardless of the attachment method used, proper installation is crucial to ensure the longevity and performance of your TPO roofing system.

Standing Seam Metal Roof – Everything You Need to Know

Wondering if a standing seam metal roofing system is the best roofing system for your property? Knowing how a standing seam metal roof is built, its advantages, disadvantages, and how long it lasts will help you determine whether it’s right or not for your project.

atlantacommercialroofingcontractors.com gathered essential information about what a standing seam metal roof is, how one is built, how it differs from a metal roof, and its long lifespan.

What Is a Standing Seam Metal Roof

A standing seam metal roof is a roofing system consisting of metal panels joined together with raised seams. The panels are typically made from steel, aluminum, or copper and come in various colors and finishes.

“Standing seam” refers to the raised seams that run vertically along the length of each metal panel. These seams are raised above the panel surface level and are typically joined together using an interlocking mechanism. When properly installed, this creates a watertight seal that prevents water from penetrating the roof.

Standing seam metal roofing systems are popular because they are extremely durable, long-lasting, and require minimal maintenance. These roofs are energy-efficient, reflecting the sun’s rays and helping keep a building’s interior cool in the summer. Additionally, they are fire-resistant and can withstand sustained high winds and other extreme weather conditions.

Components of a Standing Seam Metal Roof

A typical standing seam metal roof consists of multiple components, including the following:

• Metal Panels – These are a roof’s main structural element, typically made from steel, aluminum, or copper.
• Roof Underlayment – This protective layer is installed beneath the metal panels providing additional weather protection and preventing moisture from entering the building.
• Roof Deck – This is the roof’s foundation and is typically made from wood, metal, or concrete (depending on the structure’s construction).
• Flashing – This is typically a thin metal strip installed at the edges, penetrations, and roof seams to prevent water from penetrating the roof and causing damage or decay.
• Fasteners – These are the screws or clips used to attach the metal panels to the roof deck. They are designed to allow for the panel’s thermal movement (expansion and contraction) and prevent damage to the roof.
• Ridge Caps – These metal pieces covering the roof’s ridge (the roof’s uppermost part) provide additional weather protection.
• Snow Guards – These are devices installed on the roof to prevent snow and ice from sliding off and causing damage or injury.

Each component plays a crucial role in a standing seam metal roof’s performance and durability. Proper installation and regular maintenance of these components are essential to ensure the roofing system’s longevity and effectiveness.

Standing Seam or Metal Roof – What’s the Difference?

The terms “standing seam” and “metal roof” are frequently used interchangeably, but there is a distinct difference between them. Consider the following:

A metal roof is a roofing system made from metal materials like steel, aluminum, or copper. It can be constructed in various styles, including standing seam, corrugated, and shingle.

However, a standing seam roof is a specific metal roof type featuring raised seams that run vertically along the panels. The seams are raised above the panel surface and are typically joined using a locking mechanism, creating a watertight seal helping prevent water from penetrating the roof.

While standing seam roofs are a type of metal roof, not all metal roofs are standing seam. Other metal roof types may have different profiles, textures, and colors than standing seam roofs.

The principal difference between a standing seam roof and a metal roof is that a “standing seam” roof is a specific metal roof type featuring raised seams, while a “metal roof” refers to any roofing system made from metal components.

Standing Seam Metal Roof Pros and Cons

Standing seam metal roofs offer several advantages and disadvantages compared to other roofing systems. Consider the following pros and cons of standing seam metal roofs:

Advantages:

• Durability – Standing seam metal roofs are incredibly durable, potentially lasting 50 years or more with proper maintenance.
• Weather-Resistant – Metal roofs resist weather like high winds, hail, and heavy rain.
• Energy-Efficient – Standing seam metal roofs are reflective, helping to reduce cooling costs in warmer climates.
• Low Maintenance – Metal roofing systems require minimal maintenance and are relatively easy to clean.
• Aesthetically Pleasing – Standing seam metal roofs offer a sleek, modern look complementing various architectural styles (potentially increasing a property’s curb appeal).

Disadvantages:

• Installation Cost – Standing seam metal roofs can be significantly more expensive than other roofing systems, like asphalt shingles.
• Noise – Rain, hail, and other precipitation can be extremely noisy on metal roofs, which can be a significant concern and deciding factor for some property owners.
• Installation – Standing seam metal roof professional installation requires specialized equipment and expertise, which may add to the roof’s installation cost.
• Expansion & Contraction – Metal roofs expand and contract with temperature changes, which may cause fasteners to loosen or back out over time, potentially leading to leaks.
• Potential for Dents – Metal roofs are prone to denting when hit by large hail or other projectiles.

Standing seam metal roofs offer multiple benefits and are a popular choice for homeowners and commercial property owners wanting a durable, energy-efficient, and low-maintenance roofing solution. However, they may not be the ideal option for every roofing situation, and it’s essential to weigh the advantages and disadvantages carefully before making a decision.

What is a Parapet Wall – Definition and Purpose

Need help understanding why there is a wall around your structure’s roof? Knowing why parapet walls are necessary and what they do will help you better appreciate their cost and maintenance.

atlantacommercialroofingcontractors.com gathered essential information about what a parapet wall is, the types of parapet walls, why they are built around a roofing system, and how they drain water from a roof.

What is a Parapet Wall

Parapet walls are typically short and thin walls constructed at the edges of a building’s roof, preferably around its perimeter. A parapet wall can be constructed as a balustrade or other architectural shapes. Parapets can also be found in houses, bridges, walkways, balconies, and other elevated surfaces.

Parapet walls are principally found on flat roofs, extending the vertical wall at the side of a house or building past the roofline. They’re usually required when you want the roof to double as a terrace, balcony, facilities area, or walkway, helping to keep the area as safe and protected as possible.

Types of Parapet Walls

A parapet wall can be constructed using materials like reinforced cement concrete, brick, steel, aluminum, glass, etc. Consider the following:

Plain Parapet Walls – These are nothing more than a vertical extension of the wall at the edge of a roofing system. It is a general type of parapet wall specifically designed and constructed for safety concerns.

Perforated Parapet Walls – A perforated parapet wall is also an extension of the wall like a plain parapet, but the extended wall portion is perforated with different-sized and shaped openings complimenting the aesthetic appearance of the structure.

Embattled Parapet Walls – These parapets harken back to the olden days, especially used for castles, forts, etc. Alternative low and raised portions and strategic perforations are provided in the parapet. Archers typically used these perforations to shoot arrows through in a castle’s defense.

Note: Their beautiful appearance and uniqueness have them being constructed around modern structures to enhance their aesthetic appeal.

Paneled Parapet Walls – These parapet walls are similar to plain parapets but are ornamented with panel designs on the outside of the parapet wall.

Sloped Parapet Wall – Sloped parapet walls are used for sloped roof structures like industrial constructions, trussed structures, etc.

Stepped Parapet Wall – These parapet walls are also used for inclined roofing systems. The parapet wall is typically built in a staircase-type (step) design.

Flat Parapet Wall – Flat parapet walls are typically recommended for flat roofs.

Arched Parapet Wall – Curved or arched parapet walls are recommended for flat and inclined roofs.

Parapet walls have multiple significant purposes, including the following:

• To prevent dust and debris from collecting on the rooftop or getting into the HVAC system.
• To prevent any gathered debris on the rooftop from falling.
• To avoid high wind loads from severely impacting or damaging the enclosed roofing system.
• To provide an aesthetic look to a structure, typically increasing its curb appeal.
• Sufficiently tall parapet walls provide permanent safety protection for people when on a rooftop (inspections, maintenance, and equipment servicing) and on bridges to keep vehicles from falling or driving off the bridge.
• To hide and prevent any equipment or machinery from ruining the structure’s aesthetics or falling off the rooftop.

Note: Parapet walls are typically part of a structure’s original design.

How Do Parapet Walls Drain?

Scuppers. Roof scuppers are rectangular outlets in a parapet wall at a roof’s edge that function as a drainage device. Scuppers allow water to freely drain through an opening in a roof’s edge and are one of the most common and effective ways flat roofs drain.

Note: Scuppers are typically used in conjunction with gutters and downspouts to divert water to a desired location.

Parapet Wall

In this article, you discovered what a parapet wall is, different types of parapet walls, and how they protect a roofing system and people.

Understanding why your roof requires a parapet wall will help you better appreciate the associated construction cost and maintenance.

Improperly installed and maintained parapet walls can create a severe hazard for anyone on your roof, permit extensive wind and storm damage, and prevent your roof from properly shedding water.
