10 Advantages of a Commercial Metal Roof Retrofit

When it comes time to replace a commercial roof, building owners have two primary options - remove and replace the existing roof or opt for a retrofit solution. Key considerations include balancing the cost of the new roof with roof longevity and maintenance requirements. A metal roof retrofit often proves to be the best solution for building owners.

1. Savings on Tear Off Expenses

One of the best advantages of choosing a commercial metal roof retrofit is the avoidance of tear-off and disposal expenses associated with remove and replace options.

By choosing to retrofit the existing roof, the labor of removing the roof is avoided which can be substantial savings in itself. In addition to labor, however, you also eliminate disposal fees which can be exceptionally steep depending on your location and the material you are disposing of.

2. Less Downtime

Perhaps one of the most overlooked savings though is the fact that the business and/or operations do not need to shut down at any time. Downtime for office workers, manufacturing processes, and general business operations can be extremely disruptive and costly. When you remove a roof, some downtime is almost inevitable. Commercial roof retrofits, on the other hand, allow business operations to continue uninterrupted since the original roof remains in place.

3. Safety Considerations

Another advantage of commercial metal roof retrofits is that they are safer than remove and replace options.

During the roof removal process, workers are literally removing the platform they are standing and working on. Once the roof is removed, the installation crews are forced to work over open framing high off the ground. With roof retrofit options, however, the installation crews work and walk on the existing roof.

Another advantage of working on the existing roof is that it minimizes the chances of damage or injury from falling items like debris or tools. When the crew is working over open framing, any falling objects present a hazard for people and equipment below.

4. Shorter Construction Timeline

5. Reduced Energy Costs

Reduced energy costs are one of the potential long-term benefits of a commercial roof retrofit. During a commercial roof retrofit, you can choose to add insulation between the old roof and the new roof, or you can opt for an energy-saving ventilated air space between the two roofs if the new roof is being installed over existing shingles.

When deciding on adding insulation, building owners should realize that according to the Department of Energy, 35% of energy costs for the average building is spent on heating, cooling, and ventilation. Therefore, adding insulation can provide a big benefit in terms of heating and cooling savings.

If owners are not interested in adding insulation, be aware that this too may be another reason to consider a roof recover instead of the tear-off and replace option. When tearing off the original roof, some local codes may require that the building be updated to comply with current insulation requirements, even if that isn't a priority to the building owner. 

6. Longer Life

McElroy Metal supplies Galvalume-coated steel for all roof retrofit projects. This combination of coating and substrate is projected to last 50 to 60 years, far outlasting other roofing materials like shingles. Longer life and less maintenance lead to significant lifetime savings for commercial building owners.

7. Impact Resistance

Metal roofing used for commercial roof retrofits is rated Class 4 for impact resistance. Class 4 is the highest rating possible for roofing retrofit materials so it will hold up better against wind, hail, and debris damage saving building owners costly repairs. Class 4 roofs also lower building owner's insurance costs.

8. Curb Appeal

Each building owner is going to have an opinion about what looks best. Metal roofing is available in a variety of styles and colors, which is important for steep slope applications that are visible from the ground. There are even specialty metal roofing options available that mimic the look of shingles, slate, tile, or cedar.

For low slope applications, building owners typically opt for bare, or unpainted, metal panels because the roof is not visible from the ground. White roofs are another common option for low slope applications if the owner wants to advantage of additional energy savings due to the high reflectivity of the white roof.

9. Fire Resistance

Metal roofs are fire-resistant and deliver a safer alternative to most common roofing materials.

Metal roofing materials are all non-combustible and no more likely to be struck by lightning than other types of roofing.

10. Insurance Discounts

Add up the safety features, the damage resistance, fire resistance, and energy savings and it is clear why building owner insurance rates are often lower for a commercial roof retrofit using metal.
