Types of Commercial Roofing

Here are some of the different types of commercial roofing systems that are often used:

TPO (Thermoplastic Polyolefin)

The TPO roofing system is a single-ply system. It’s used for commercial buildings and is made up of reinforced scrim and a single layer of synthetic materials. This is applied to roofing in a single layer for faster installation.

There are both pros and cons of using any type of roofing system. Here is more information on TPO:

  •         Reflects the UV rays.
  •         It’s not as expensive as other roofing systems.
  •         Can be put on the roof quicker.
  •         Saves on manufacturing costs.
  •         It’s better than it was in the past.
  •         Has 45-mil, 60-mil and 90-mil thickness.
  •         Lasts 10 years to 25 years.

Here are some other roofing systems that are often used on commercial buildings:

PVC (Polyvinyl Chloride)

PVC is a single-ply roofing material and is used for commercial buildings. It’s high quality and is used to restore roofing with longevity. It can last longer than materials like TPO. This is made of white material, so it’s naturally reflective of the sun.

There are both pros and cons when using PVC such as:

  •         Blocks UV rays.
  •         It’s an older type of material.
  •         Can be more expensive than TPO.
  •         Lasts between 15 and 30 years but depends on how it is installed and the mil thickness.

EPDM (Ethylene Propylene Diene Terpolymer)

  •         Single-ply.
  •         Original materials.
  •         Made of black material but can come in white.
  •         Comes in 45-mil or 60-mil thickness.
  •         Great for colder climates.
  •         It’s made with rubber, so it’s flexible.
  •         Made by places such as Firestone.
  •         Can last for 25 years or more.
  •         The seams sometimes fail.
  •         It’s not heat-welded at the seams.
  •         Needs thicker material if having equipment on the roof.
  •         Comes in 50-foot rolls.
  •         Two methods, tape or glue.

Metal Roofing

  •         Comes in R-panels and standing seam.
  •         Standing seam has a tall rib.
  •         The fasteners on the standing seam are hidden.
  •         Standing seam is usually used in high end buildings.
  •         R-panels are more common.
  •         R-panel metal roofs are lower cost.
  •         Standing seam is more expensive.
  •         R-panel has the fasteners exposed.
  •         Fasteners can become loosened over time due to thermal movement.
  •         Can last up to 50 years or more.

VLR Homes, LLC



We have engaged Francisco and VLR Homes 3 times now. From painting the house, remodeling a master bath and constructing a screened in porch area they have responded with quality work at a fair price. When things came up like they always do, VLR had a solution (some panels of 50 year old siding replaced with Tyvek and up to code replacement). Again, at a fair price and done right the first time. Francisco is responsive with the good and the bad news  straight up and always with a plan. We intend to use VLR in the future for projects large or small.
