Commercial roofing systems are more complex than your average residential roof. They include insulation, air ducts, drainage, waterproofing, flashing and fastenings to protect your building from rain.

There are many types of commercial roofing materials, including single-ply membranes, built-up roofs, and modified bitumen. Each has advantages and disadvantages. Choosing the best material for your building is critical.



One of the most popular choices for commercial roofs, metal is a durable and affordable material that’s also an incredibly versatile Commercial Roofer in Detroit, MI. It can be painted in virtually any color to match a building’s decor or enhance its style.

The best metal roofs can last more than a century, so you can expect to enjoy many years of maintenance-free use. They’re also known for their energy efficiency, which can save you money on your heating and cooling costs.

The type of metal you choose will depend on your region’s weather conditions and your budget. Through-fastened corrugated panels are the most common, but modular panels are also a good option if you want a more unique roof.


PVC, or polyvinyl chloride, is a lightweight and chemically impervious material that’s typically used on flat roofs. It contains less oil and petroleum than TPO and EPDM roofing materials, making it a popular choice for commercial buildings.

A PVC membrane is installed over an insulation layer that may include ISO or EPS foam boards. The membrane is then welded together with a hot air gun.

PVC is a popular choice for commercial roofing because of its durability. It can last up to 25 years, making it a great investment.


Green roofs are a great addition to your commercial property. They add usable space, enhance your building’s appearance and increase its value.

They are also eco-friendly, as they help reduce air pollution and provide a cooling surface during the summer. They also filter stormwater runoff, which saves money on water treatment costs.

It’s important to understand the different types of green roof before you get started on your project. First, you need to determine the type of roof that will work best for your business.

This will require a lot of consideration, including the weight capacity of your building. In addition, you’ll want to choose a system that will be easy to maintain. A chartered structural engineer or architect will be able to help you determine this.


TPO is a single-ply thermoplastic membrane that is known for its durability and energy efficiency. It is also an environmentally friendly material because it doesn’t contain chlorine, a chemical found in some other roofing materials.

TPO’s white color helps reflect the sun’s rays, keeping the building cooler and lowering cooling costs. In addition, it is ENERGY STAR rated.

Thermoplastic polyolefin, or TPO for short, is a single-ply roofing membrane made of a blend of ethylene-propylene rubber and polypropylene. It has been around since the 1990’s and is used for flat roof applications.

TPO is a durable and resilient material that stands up well against rain, hail, and snow. It is also resistant to chemicals and grease, which makes it a good choice for roofs with a lot of exposure to these substances.


Shingles are the most common type of commercial roof and are a great choice for many property owners. They come in a variety of styles and colors, are fire and wind resistant, and offer good value for the money.

Roofing professionals can help you select the best shingle for your building’s needs. They will also ensure that your roof is properly installed and lasts for years to come.

The first row of shingles is called a starter course or strip. These are usually created by snapping three-tab shingles in half and applied to the eaves, with self-sealing adhesive pointing up along the ridge.

Architectural shingles are a step up from 3-tab shingles and feature two or more layers to replicate the look of natural slate or wood shakes. These shingles are thicker and more durable than their 3-tab counterparts, but may add to the cost of your commercial roof. They also must pass impact-resistant testing.
