4 Types of Commercial Roofing Systems and Their Advantages

Commercial Roofing Systems

If you’re a business owner who is thinking about building or reroofing your own commercial building, you need to make many decisions. The roofing system you choose is one of the most important decisions.

A commercial roof protects the entire building from the elements. The insulation inside a roofing system also helps to keep the building energy efficient. Not only does the right roofing system add structural integrity to the building, it keeps personnel inside the building safe and comfortable.

In order to help you determine the best kind of roof for your commercial building, here are four types of commercial roofing systems and their advantages.

Installing a Roof During Business Hours? How to Manage Business

Reroofing your business during business hours can be a challenge. Some businesses close during a commercial reroofing project, while others remain open. Either way, a commercial reroofing project requires a lot of coordination and preparation. If your business needs a roof installation in the coming months, take a look at what you need to do in order to be prepared. 

Hire a Reputable Commercial Roofer

First, hire a reputable commercial builder. Experienced builders know how to work with business owners in order to get the roof up with the least amount of disruption possible. When you interview commercial roofers, ask them questions such as: 

Managing Rooftop Fixtures on Standing Seam Metal Roofs

A standing seam metal roof will last 40 to 70 years on your commercial building. At the same time, the roof can reduce cooling costs, resist flames from wildfire or lightning, and sustain high winds. However, rooftop features, including HVAC units, vents, and solar panels, must be installed carefully on the standing seam metal roof. Take a look at three things you should know about this process.

  1. Insist on Tested Metal Panels

The standing seam metal roof is considered a hydrostatic or water-barrier-type roof. The standing seam metal roof panels are formed from uncoiled metal that’s cut to width and roll-formed into the correct seam arrangement. Panels are then cut to length for stock or custom roofing purposes.

5 Facts to Know About Snow Loads on Commercial Roofs

With winter at the doorstep, commercial property owners must be vigilant to avoid roof collapses due to snow loads. Here are five things to know about commercial roofs and snow loads.

  1. The Weight of Snow and Ice

Minnesotans can expect between 31 and 86 inches of annual snowfall depending on their location in the state. However, not all snow weighs the same amount.

Which Green Roof Is Best for Your Facility?

If you’re installing a green roof on a commercial building, you’ve made a wise choice. Green roofs provide economic benefits by reducing energy costs, increasing HVAC efficiency, and extending roof life. Green roofs also enhance neighborhoods by cutting greenhouse gas emissions, improving air quality, and curbing the urban heat-island effect.

The green roof you select for your structure will be one of two basic types. These two types of roofs are called extensive and intensive roofs. Here’s more information to help you choose the best type of green roof for your commercial building.

Is Your Flat Roof Near the End of Its Life?

Flat roofs are one of the most common types of rooftops found on commercial buildings. They’re common because they’re space efficient, easy to maintain, and good for supporting large air-conditioning units. If you’re a business owner who is concerned about making the best use of your building’s square footage, a flat roof is probably the best type of roof for your needs.

That said, flat roofs don’t last forever. You need to maintain your flat roof and replace it before it loses its structural integrity, especially in places like Minnesota, where snowfall can be heavy and wet in winter.

A flat roof that is not well maintained could buckle under the stress of a heavy snow or could leak and cause structural damage to your building. Knowing when your flat roof needs to be replaced can help you take care of your commercial property. 

3 Reasons to Enclose Your Building in Insulated Metal Paneling

Insulated metal panels (IMPs) have come a long way since the first structural insulated panels (SIPs) were conceived in the 1930s. Today’s structural panels are manufactured in a wide array of styles and materials to meet enclosure requirements for most commercial operations. Here are three benefits of enclosing your structures with IMPs.

  1. IMPs Offer 5 Key Functions in One Product

The IMP panels installed on your buildings provide five valuable features in one product. Due to the unique way the panels interlock, IMPs form a superior barrier around buildings.

An IMP enclosure around your structure offers protection from:

3 Facts About Green Roofs on Commercial Buildings

Does your commercial structure have a flat or slightly sloped roof? If it does, install a green roof and reap the rewards of sustainability. Here are three facts about green roofing systems on commercial buildings.

  1. You Can Choose How Deep to Plant

A green roof is green in the sustainable sense and by its visual impact. Over a special waterproof system, plants are installed in growing medium. The placement and selection of plants determine whether you create a lush patch of grass or a roof-top walkway with shade trees and flowering plants.

You can choose from three levels of green roof installations. Your choices may be limited by your roof load and the accessibility of the roof. The three main types of green roofs along with general descriptions are listed here.

4 Benefits of a New Commercial Roof Installation

It’s a big deal to have your entire commercial roof replaced. Some facility managers realize their structures need better top enclosures, but they put off having new roofing materials installed until serious roof-related damage occurs.

However, a new commercial roof is a net positive for your building. Learn about four benefits you receive with your brand new commercial roof.

  1. You Improve the Safety of Your Building

As building technology increases, knowledge about the safe construction of buildings also grows. Building designers continue to develop new materials and construction techniques for the safety of people who must maintain the exterior of buildings.

4 Reasons to Choose Metal Roofs

Whether you’re recovering a structure or planning the roof design for a new building, metal roofing is a solid choice. Here are four reasons why.

  1. Long Life and Durability

According to a recent study, building owners rank the service life of roofing material as their most important consideration when selecting roofing products. The more durable the roofing material, the longer it lasts.

Maintenance of the roof is another factor related to its durability. Each roofing type costs a percentage of its total installed cost to maintain over the lifetime of the roof.

The following maintenance-cost comparisons were reported by building owners for their steep slope roofing types in percentages:

  • Asphalt shingles — 28.5 percent
  • Single-ply membrane — 19 percent
  • Metal roofing — 3.5 percent
