Even the toughest roofing will need to be replaced at some point. When it comes to repairs or replacing roofing, you have several options. But how do you know which is best for your commercial roofing?

What Is The Best Type Of Warehouse Roofing?

There are advantages and disadvantages to the common types of commercial roofing. Here is what you need to know:

Liquid-Applied Roofing

These are essentially custom roofing options because they can be applied around existing fixtures. Liquid materials are seamless, and can easily fill in any gaps to improve water resistance. You will often need to use fabrics for reinforcement and always apply liquid roofing to an existing structure. The most common liquid applications are:

  • Acrylic coatings: These are great for low-sloping roofs and are resistant to heavy traffic and impact. Apply these with a brush or roller, just like paint.
  • Silicone coating: You get more water resistance with this coating so it is ideal for roofing that is prone to pooling. They are less durable to impact compared to acrylic options.

Built-up Roofing

If you have a budget, built-up roofing is the most affordable. Along with pricing, the biggest advantage to this option is its insulating qualities. The layers of membranes, sealants, and gravel offer optimal insulation. These layers are also heavy, so you need to make sure you have support in place for the additional weight.

Modified Bitumen

Bitumen is mixed with rubber and then these sheets are glued to the roof. You get a thick protective roofing layer that is much lighter than built-up roofing. This is also a popular option due to affordability and reflective properties which keep heat away from the building.

TPO Roofing

This single sheet is lightweight but highly reflective. It is popular because it can be applied while the building is occupied and saves a lot of energy in hot climates. TPO sheets are durable but only last for a decade or so. They need to be replaced as soon as they are worn as leaking can easily occur. With regular preventative maintenance, these sheets can last longer.

Metal Roofing

Metal lasts the longest but is also the most expensive. You can use metal sheets or tiles and they can be designed to look like other materials. Steel is the most common material and is often mixed with another material to enhance durability. A coating is often needed to prevent corrosion. Aluminum is cheaper but more durable and lighter weight. Zinc is pricey too and mostly used for roofing in high-stress areas such as saline water areas or high chemical exposure.
