Acrylic Coating


Flat roofing systems are typically installed on commercial properties, modern homes, and homes that have a flat or very low pitch. One of the most sought after flat roofing material is TPO.


TPO is made of polyoefin rubber membrane that covers the surface of the roof. It is energy effcient, strong, durable and an economic choice.


Other flat roofing materials we offer are PVC, EPDM, Bitumen and Aluminum Coating.


Single-Ply TPO Membrane 

 Thermoplastic Polyolefin single-ply roofing

 Our TPO roofing products offer a cost effective solutions for your flat roof,  while ensuring you get long term performance and durability.
 
 Advantages of TPO Roofing
 
If properly installed and maintained, a commercial single-ply membrane roof can last 30 years. There are quite a few other benefits of single-ply membrane roofing systems:

TPO is ENERGY STAR rated and meets the higher standard for California's Title 24. 

TPO membranes are mold resistant, impact resistant, wind resistant, fire and traffic resistant.

Class A Fire-Rated – TPO membranes and EPDM can achieve Underwriters Laboratories (UL) Class A fire resistance listings by adding fire retardant chemicals during the manufacturing process. Carlisle is one of few membrane manufacturers that can achieve U.L. Class A Fire Ratings on unlimited slopes, such as can be found on steep barrel roofs.
 
Reflective or Retentive – TPO is generally white and highly reflective. On the other side of the spectrum, EPDM is often described as “Black Roofs,” due to the natural dark color of the membrane.

Membrane Sheet Width – Carlisle manufactures the TPO membrane in various widths of 4, 6, 8, 10 and 12 feet. The different widths are used in various wind zones in accordance with building height and deck type. This allows for the roofing system to be “customized” meeting specific requirements for any given project. The design criteria for those various building conditions are outlined in the Carlisle published specifications.

App Torch

Torch down roofing is so named because it requires an open-flame propane torch. In this installation method, sheets of modified bitumen are rolled out onto the roof, and a roofing professional uses a hand-held propane torch to heat the material and adhere it to the surface. Once the layers reach the right temperature, seams are melted together to create a waterproof seal.

Types of Roof Coating

  • 1. Acrylic

    Acrylic roof coatings are among the most durable and inexpensive elastomeric coatings in the industry. Comprised of high solids emulsion polymers and potent biocides, these highly reflective coatings are ideally suited for extreme UV climates and provide superior resistance to mildew and dirt accumulation.

    Acrylics do not stand up well to ponding water and are only recommended for roofs with positive drainage. Cold temperature applications can also be a problem.

  • 2. Silicone

    Silicone roof coatings are the preferred choice when it comes to UV protection and resistance to ponding water. They erode much slower than other coatings without becoming brittle or hard. Modern silicone formulations have a high-solids content that typically exceeds 90 percent. This means less material is needed to achieve the required dry film thickness.

  • 3. Urethane (Polyurethane)

    Urethane (Polyurethane)

    When it comes to strength, durability, and adhesion, urethane roof coatings are second to none. Compared to other coatings, they are more impact-resistant and are better suited to handle pedestrian traffic. They are also strong enough to endure the natural expansion and contraction (thermal movement) of roof structures and the negative effects of ponding water.
