When it’s time to replace a commercial roof, one option is retrofitting. Steel paneling in this scenario is installed over the existing roof, but with a substructure that provides additional slope for water and snow runoff.

Save on Tear Off Expenses

One of the first advantages of choosing a retrofit commercial roof is that it avoids the 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. In addition to labor, you also benefit by avoiding disposal fees of existing tear off materials, which can be expensive, depending on your location and the material you’re disposing.

Perhaps one of the most overlooked savings though is that a business does not need to close during business hours due to the construction. Hours of inoperation can be costly to any business, and this process allows little disruption. With roof removal, disruption will take place at some point. Since the original roof remains in place, commercial roof retrofits allow businesses to operate normal hours.

Safety

Adding a roof over an existing roof is also much safer working conditions for installers. The installation crews are able to work on, and walk on the existing roof while doing their job of installing the new one.

Shorter Construction Timeline

The overall cost of the project will be reduced, since the overall construction timeline is much shorter than the standard “remove and replace” option. Installation crews can begin installing the new roof right over the existing roof without the time and expense of removing the old roof first.

Reduced Energy Costs

The Benefits of installing a steel roof over an existing roof also may decrease energy costs in the long-term.

The building owner can choose to add insulation between the old roof and the new roof, or opt for an energy saving ventilated air space between the two roofs.

When making the decision about adding insulation, it’s important building owners realize that according to the Department of Energy, 35% of energy costs for the average building is spent on heating, cooling, and ventilation. Adding insulation will most certainly benefit the business or building owner in terms of heating and cooling energy savings.
