Comparing Commercial Roofing Estimates: A Comprehensive Guide

If you need your commercial roof replaced or repaired, you’ll begin the process by selecting a commercial roofing company. Understanding what to look for when comparing each estimate will allow you to make an informed decision that will significantly impact the cost, quality, and longevity of your roof.

With over 70 years of experience as a reputable commercial roofing company, we understand the challenges building owners and managers face when navigating the process of obtaining and comparing commercial roofing estimates. In this article, we hope to unpack the process, offering insights and advice to help you make a choice that aligns with your building’s needs and your financial considerations.

What An Estimate Includes

It’s important to understand that a commercial roofing estimate is more than just a price quote. In addition to the estimated cost, it’s a detailed proposal that outlines the scope of work, materials to be used, timeline, and warranty information. When you request an estimate, you’re essentially asking for a roadmap of the project from start to finish.

When comparing estimates, it’s essential to dive into the details. Here are some key factors to consider:

Scope of Work

The biggest differentiator in a commercial roofing quote is the scope of work. At Maxwell Roofing, our goal is always to develop the project with the client so the scope of work aligns with your plans for your facility. Our process doesn’t always result in the cheapest bid, but we always provide the best solution to meet a client’s needs.

When you’re comparing the differences in pricing between the estimates, ask yourself the following questions:

  • Do the various estimates include the same proposed scope of work?
  • Is the work to be performed clearly detailed?
  • What materials will be utilized?

Ensure that each estimate clearly defines all work that will be done. This could include the removal of the old roof, preparation, installation, and cleanup. A detailed scope of work helps prevent unexpected costs and misunderstandings.

Think Long-Term

To assess the true value of a roofing proposal, consider the average cost of maintenance and repairs for the life of the roof. Certain types of roofs may be inexpensive up front, but they will cost more to maintain and may not last as long. The same is true with investing in a quality roofing contractor rather than a budget contractor. It may cost more upfront to hire a reputable roofer, but your roof will last longer, saving you more money in the long run.

Materials

The type and quality of materials used in a project can vary, and not all of these materials are created equal. Certain roofing materials may be required to meet building codes. Before you sign a contract, understand the pros and cons of each material option and how it aligns with your building’s needs and your budget.

Insurance and Licensing

Appropriate business elements are just as important as the scope of work and performance. For example, is the roofing contractor licensed to operate in your specific state and county? Do they have proper insurance coverage? Will they meet the requirements of your current building codes and permits?

Many roofing companies include proof of insurance, business licenses, liability information, and payment terms with the proposal. If the roofing company does not include that, be sure to ask for these documents before hiring them.

Ask The Right Questions

Do your due diligence to make sure the companies you’re considering for a job are experienced and reputable. Good roofing companies keep track of their best work and retain references from past customers. Remember that you can always ask for referrals or previous customer testimonials. You can also request bank, vendor, or manufacturer certification letters to confirm the company’s legitimacy.

Some additional important questions include:

  • How are unforeseen issues handled during the project?
  • How do you ensure the project stays on schedule and within budget?
  • What safety measures do you implement during the project?

Without knowledge of the roofing industry, it can be difficult to know if you’re being quoted a fair price on a reasonable deadline. That’s why we’ve created a guide to give you an inside look at what goes into building a quote so you can feel even more confident during and after the decision-making process.

Commercial Roofing FAQs: How long is your roof designed to last?

As a commercial property manager or building owner, one of the most important concerns you have is the longevity of your roof. After all, it’s your first line of defense against the elements, and it ensures the comfort and safety of your occupants. But how long can you expect your roof to last?

With nearly 70 years of experience in commercial roofing in Tennessee and Alabama, our team at Maxwell Roofing understands the factors that impact roof lifespan. We’ve also witnessed the evolution of our industry as materials become more durable, maintenance practices shift, and building owners increasingly prioritize roof longevity. 

After partnering with hundreds of building owners and property managers over the years, one question consistently tops our list of inquiries: “How long is my commercial roof expected to last?” In this blog, we hope to answer some of the most common questions related to roof longevity to help you make informed decisions about your property.


1. What is the expected lifespan of a commercial roof system?

The good news is that with proper care and maintenance, a well-constructed roof system can last 20 years or more. However, this isn’t a one-size-fits-all answer. The lifespan can vary significantly depending on several factors, including:

  • Interior conditions. Is your building subject to high humidity, temperature fluctuations, or chemical exposure? These factors can put stress on your roof and shorten its lifespan.
  • Building design. The slope of your roof, the presence of roofing penetrations like skylights or vents, and the overall structural integrity all play a role in how long your roof will last.
  • Maintenance best practices. Regular inspections, prompt repairs, and proper cleaning are essential for extending the life of your roof. Neglecting these crucial steps can lead to rapid deterioration and costly repairs.

2. What factors can potentially shorten the lifespan of the roofing system?

The biggest threat to your roof’s longevity is neglect. Just like a car, your roof needs routine attention. Annual inspections are essential, especially after major weather events, to catch potential problems before they escalate. But neglect isn’t the only culprit. Here are other factors to watch out for:

  • Abuse. If your roof is used for purposes it wasn’t designed for (e.g., excessive foot traffic, storage), it can suffer premature damage.
  • Improper installation or maintenance. Inexperienced contractors or workers unfamiliar with your specific roof type can cause problems during installation or repairs.
  • Incompatible materials. Using the wrong materials for penetrations or repairs can lead to chemical reactions and compromise the integrity of your roof.
  • Changes in building use. If you change the interior function of your building (e.g., adding a restaurant tenant with grease exhaust), it can stress your roof system and lead to unexpected issues.

3. What can we do to extend the lifespan of our commercial roofing system?

Maximizing your roof’s lifespan starts with choosing the right system and prioritizing its health. Here are some key considerations:

  • Make regular inspections and maintenance a priority. This is the single most effective way to catch problems early and prevent them from becoming major issues.
  • Choose a roof system that’s right for your building and its intended use. Don’t prioritize cost over compatibility. For example, a modified bitumen system might require a more significant up-front cost, but the long-term costs are often less because this system offers superior longevity. In the same way, single-ply membranes are a more cost-effective solution that can last 20+ years, but maintenance costs will be higher, especially toward the end of the roof’s life cycle.
  • Minimize penetrations and foot traffic on your roof. Every hole is a potential entry point for water and wear. Additionally, keep unnecessary foot traffic off your roof. Every step increases the risk of damage, especially on single-ply membranes.
  • Repair any problems promptly. Don’t let small leaks or tears turn into major headaches.

4. What should we do if we think it might be time to replace our roof in the next 2-3 years?

If you suspect your roof may need replacing within the next 2-3 years, proactive planning is key. Here’s what you should do:

  • Consult with a qualified roofing professional who can help you make key decisions. Choosing a qualified roofing contractor that you know and trust is an important business decision. They can assess your roof’s condition and recommend the best replacement options.
  • Develop a budget. The next step in preparing for a roof replacement is to develop a budget. It’s important to be proactive rather than reactive. 
  • Plan ahead for logistical issues. Logistical obstacles and unexpected setbacks can make a significant difference in a successful project. For example, if you manage a manufacturing plant, you’ll want to consider how a reroofing project will affect your day-to-day operations: Will the plant need to shut down for the duration of the project?  Or will the roofing contractor need to plan to work specific hours to avoid a shutdown? Making important decisions like these before you get started can help your commercial roofing contractor develop an appropriate scope of work and mitigate the possibility of running into any issues when it’s time to start your re-roofing project.
