What are the most common commercial roofing types used on commercial buildings in Minnesota? In this blog, we’ll explore this question and discuss the types of roofing materials commonly used to keep our buildings dry.Minnesotans have bragging rights when it comes to extreme climate. With 140-degree temperature swings from summer to winter, we see almost every sort of weather (except hurricanes). We have rain, snow, hail, sleet, freezing rain, ice, and wind. And for 3 or 4 months of each year, we experience frequent freeze/thaw cycles.

What are the considerations in deciding on a commercial roofing type?

When building a new commercial building, architects and contractors typically decide the type of roofing system used. They will consider many factors, including energy efficiency, lifespan, durability, maintenance requirements, environmental factors, and of course, budget. 

Some types of commercial roofs are less expensive to install than others but may be more costly to maintain over the roof’s lifespan.

What types of commercial roofing does Mint Roofing install?

At Mint Roofing, we work primarily with three types of commercial roofs:

  1. Built-up Roofs
  2. Single-Ply Membrane Roofs
  3. Sheet Metal Roofs

1. Built-Up Roofs

Built-up roofs, as their name suggests, are roofs made of multiple layers of material. Most commonly, they consist of layers of tar and gravel. Multiple layers increase the durability of a built-up roof but increase the cost with each layer.

One of the oldest types of commercial roofs, built-up roofs hold up well to foot traffic but require a stable foundation with minimal vibration to preserve their integrity. Built-up roofs are resistant to UV damage..

Pros: Durable
Cons: Average lifespan

2. Single-Ply Membrane Roofs

Single-ply membrane roofs consist of a metal substructure covered with a material covering the entire roof’s surface. Mint Roofing has years of experience installing the most common types of single-ply membrane roofs.

EPDM (Ethylene Propylene Diene Terpolymer) is a synthetic rubber material that provides average durability and resists damage from sunlight and most pollutants. It has a long life and is relatively easy to install as a new or replacement roofing material. EPDM is available in white or black.

Pros: Long lifespan
Cons: Low durability

TPO (Thermoplastic Polyolefin) and PVC (Poly Vinyl Chloride) are options well suited for extreme environments. They perform well in hot and cold temperature extremes and are resistant to UV, most chemicals, oils, fats, and punctures. TPO and PVC roofs will tolerate strong winds and have the added benefit of reflecting heat away from the building in the summer months.

The popularity of these materials has led many roofing contractors to cut corners and use cheaper knock-off materials. Rest assured that Mint Roofing uses only the highest quality materials 

Pros: Long lifespan
Cons: More expensive

3. Sheet Metal Roofs

They have a long life expectancy, but some are susceptible to corrosion, particularly in our harsh northern climate. Months of accumulated snow cover can lead to oxidization and corrosion, increasing the likelihood of leaks. To prevent this, metal roofs are often treated with a protective coating.

Pros: Long lifespan, fire resistance
Cons: Susceptible to corrosion
