Commercial Roofing Contractors: What You Need to Know Before Hiring One

If you own a commercial property, you know how important it is to maintain it properly. One of the most critical components of any building is its roof, as it provides essential protection against the elements. But what do you do if your roof needs repairs or replacement? That’s where commercial roofing contractors come in. In this article, we’ll discuss everything you need to know before hiring one.

What Are Commercial Roofing Contractors?

Commercial roofing contractors are professionals who specialize in installing, repairing, and replacing roofs on commercial buildings. Unlike residential roofs, commercial roofs are often larger and more complex, requiring specialized knowledge and equipment.

Why Do You Need a Commercial Roofing Contractor?

Commercial roofing contractors have the expertise, experience, and equipment necessary to handle all aspects of commercial roofing, including installation, repair, and replacement. They also have access to specialized materials that may not be available to the general public. Without proper training, attempting to repair or replace a commercial roof yourself can be dangerous and costly.

How Do You Choose the Right Commercial Roofing Contractor?

Choosing the right commercial roofing contractor is crucial to ensure that your roofing project is completed on time, within budget, and to your satisfaction. Here are some factors to consider when selecting a contractor:

1. Experience and Reputation

Look for a contractor with several years of experience and a positive reputation in the industry. Check online reviews, testimonials, and references to get a sense of their work quality and customer service.

2. Licensing and Insurance

Ensure that the contractor you choose has the proper licensing and insurance to protect you and your property in case of any accidents or damages.

3. Expertise and Specialization

Choose a contractor with expertise and specialization in the type of roof your commercial building has. For example, if you have a flat roof, look for a contractor with experience in installing and repairing flat roofs.

4. Price and Payment

Get multiple quotes from different contractors and compare prices. Don’t choose a contractor based solely on the lowest price, as this can sometimes result in subpar workmanship. Also, make sure you understand the payment terms and schedule before signing a contract.

Types of Commercial Roofs

There are several types of commercial roofs, each with its own advantages and disadvantages. Here are some of the most common types:

1. Built-Up Roofing (BUR)

A BUR roof consists of several layers of felt or fabric material that is saturated with asphalt and then topped with a layer of gravel or other granular material. BUR roofs are durable and long-lasting but can be heavy and expensive to install.

2. Modified Bitumen Roofing

Modified bitumen roofing is similar to BUR roofing but with added layers of polymer-modified asphalt. This type of roof is more flexible and easier to install than BUR roofing.

3. Single-Ply Roofing

Single-ply roofing is a popular option for commercial buildings, consisting of a single layer of synthetic material such as PVC or EPDM. This type of roof is lightweight, easy to install, and highly resistant to leaks.

4. Metal Roofing

Metal roofing is a durable and long-lasting option that can be customized to fit a variety of architectural styles. It is also highly energy-efficient and can save you money on heating and cooling costs.

The Commercial Roofing Process

The commercial roofing process typically involves several stages:

1. Inspection

A commercial roofing contractor will perform a thorough inspection of your roof to determine the extent of any damage and the best course of action.

2. Preparation

The contractor will prepare the roof for repair or replacement by removing any debris or damaged materials and ensuring that the surface is clean and free of any contaminants.

3. Repair or Replacement

Depending on the extent of the damage, the contractor will either repair or replace the damaged sections of the roof. This may involve patching, sealing, or replacing entire sections of the roof.

4. Inspection and Maintenance

After the repairs or replacement are complete, the contractor will perform a final inspection to ensure that the roof is in good condition and performing as expected. They may also recommend regular maintenance to keep the roof in good condition and prevent future damage.

Benefits of Hiring a Commercial Roofing Contractor

Hiring a commercial roofing contractor offers several benefits:

1. Safety

Roofing work can be dangerous, particularly for those without proper training and equipment. Hiring a contractor ensures that the work is done safely and according to industry standards.

2. Quality Workmanship

Commercial roofing contractors have the expertise and experience necessary to complete the work to a high standard, ensuring that your roof performs as expected and lasts for many years.

3. Time and Cost Savings

Attempting to repair or replace a commercial roof yourself can be time-consuming and costly, particularly if you don’t have the proper equipment or materials. Hiring a contractor can save you time and money in the long run.


Maintaining your commercial property’s roof is essential to protect your building and ensure its longevity. Hiring a commercial roofing contractor can ensure that your roof is repaired or replaced to a high standard, keeping your property safe and secure.


  1. How long does a commercial roof typically last?

Commercial roofs can last anywhere from 10 to 50 years, depending on the type of roof and how well it is maintained.

  1. How often should I have my commercial roof inspected?

It is recommended to have your commercial roof inspected at least once a year, preferably before and after the winter season.

  1. Can I repair my commercial roof myself?

It is not recommended to attempt to repair a commercial roof yourself, as it can be dangerous and may result in further damage or costly mistakes.

  1. How do I choose the right type of commercial roof for my building?

Choosing the right type of commercial roof depends on several factors, including your budget, building size and shape, and environmental factors such as climate and weather patterns. A commercial roofing contractor can help you choose the best option for your needs.
