The Best Types of Commercial Roofs: A Guide for Businesses

What's the Best Commercial Roof Type for My Building?

What's the best commercial roof type for my building?

There isn't one "best" commercial roof type for every building. The right choice depends on your specific building, what you use it for, where you're located, and what condition your existing roof is in. It's about finding the best fit for your needs.

Symptom

You might be noticing leaks, higher energy bills, or just that your roof is old and looks worn out. Maybe you're building a new facility and need to pick a roof system from scratch. You've probably heard about different roof types like metal, EPDM, TPO, or foam, and you're trying to figure out which one makes the most sense for your business.

Problem

Choosing the wrong roof system, or delaying a needed repair or restoration, can lead to big problems. Leaks can damage inventory, equipment, and the building structure itself. A poorly performing roof can drive up your heating and cooling costs, eating into your profits. If you just put a new roof on without considering all the factors, you could end up with an expensive system that doesn't last as long as it should or doesn't deliver the energy savings you expect. Ignoring these issues means you're paying more in the long run, both in energy and future repair costs, while risking significant damage to your operations.

Solution

First, it's important to understand the main roof types out there. Keep in mind that for many existing roofs, a full tear-off isn't the only answer. Often, a commercial roof restoration system can bring new life to an old roof, saving you money and time.

Common Commercial Roof Types:

• Metal Roofs: These are tough and last a long time, often 30 to 50 years. They're good in all kinds of weather. While you usually see them on sloped roofs, special systems are made for flat roofs too. Metal roofs can be expensive upfront, but their long life and low maintenance can balance that out.
• EPDM Roofs: Often called "rubber roofs," EPDM is a single-ply membrane common on flat roofs. It's pretty affordable and naturally resistant to fire. They can last up to 30 years. Modern EPDM now comes in white, which helps reflect sunlight and save on cooling costs.
• TPO Roofs: Another single-ply membrane, TPO is gaining popularity. It's lightweight, easy to install, and resistant to mold. Like white EPDM, TPO is reflective, which helps keep buildings cooler in hot weather, saving energy. TPO roofs generally last around 30 years.
• Foam Roofs (SPF): Spray Polyurethane Foam (SPF) is applied as a liquid that expands and hardens into a solid, seamless layer. It creates a great insulation barrier and is naturally waterproof. Foam roofs are good on their own, but they also make a great base for protective coatings.

When Restoration is the Right Move:

Many of these roof types—metal, EPDM, TPO, and even existing foam roofs—can often be restored instead of replaced. A Conklin-trained contractor can apply a commercial roof restoration system, like a Conklin acrylic coating, right over your existing roof. This process involves:

1. Cleaning: We start by thoroughly cleaning the roof surface to remove dirt, debris, and any loose materials.
2. Repairing: Any damaged areas, like leaks, cracks, or seams, are carefully repaired and reinforced. This might involve replacing a few panels on a metal roof, or sealing up punctures on an EPDM roof.
3. Priming: Depending on the roof type, a primer might be applied to ensure the new coating sticks properly.
4. Coating: We then apply one or more layers of a high-performance Conklin acrylic coating. This creates a seamless, waterproof, and often reflective barrier over your existing roof. For example, our flat roof coating systems extend roof life and reduce energy use. For foam roofs, we often apply a top coating to protect the foam from UV rays.

This approach saves you the cost and disruption of a full tear-off. It extends the life of your roof, seals leaks, and can significantly improve your building's energy efficiency. However, restoration isn't always possible. If your roof insulation is saturated with water, the deck is rotten, or the roof has simply failed too far, a full replacement may be the only option. An on-site inspection by a Conklin-trained professional is the only way to know for sure.

Frequently Asked Questions

What is a commercial roof coating?

A commercial roof coating is a liquid material applied directly over an existing roof system. Once it dries, it forms a seamless, durable, and waterproof membrane. These coatings protect the roof from weather, extend its lifespan, and often reflect sunlight to reduce building cooling costs.

How long do commercial roof coatings last?

Conklin acrylic roof coatings are designed to last for many years, often adding 15-20 years or more to an existing roof's life. The actual lifespan depends on the original roof's condition, the type of coating, and how well it's maintained. Many systems are renewable with a simple recoat after their initial warranty period.

Is a roof coating cheaper than replacing the roof?

In most cases, yes, a roof coating is significantly cheaper than a full roof replacement. It avoids the high costs of tearing off and disposing of the old roof, and it often has lower labor costs. Plus, the improved energy efficiency from a reflective coating can lead to further savings over time. The exact savings vary based on your roof's condition and size.

Choosing the right roof or restoration system for your building is a big decision that affects your energy bills and protects your assets for years to come. Don't guess. A Conklin-trained contractor can assess your roof's condition, discuss your needs, and recommend the best system for your building.
