Can I Install a New Roof over My Existing Roofing System?
Whether or not a new roof can be installed over your existing roof depends on many different factors, but you can install a new roof over your business’s existing roof, and it can be a great option. If you have questions or concerns about your commercial roof, it’s time to consult with an experienced Florida commercial roofing company.
Considering Your Options
Simply installing a new commercial roof over the one that’s already there reduces the amount of overall labor required and does away with the time and expense associated with disposing of the old roof. This approach to roofing is called a roof overlay or re-roofing, and while it can be an excellent choice, it’s not always a good idea – or even doable. The factors that will guide your decision of whether to install a roof overlay include all the following:
- Your building’s structure and its weight-bearing capacity
- Local regulations
- The condition of your building’s current roof
Getting Started
To begin, a commercial roof pro will conduct a detailed inspection of your business’s current roof. In the process, they’ll be looking for the warning signs of significant damage, including:
- Water infiltration
- Structural concerns
- Degradation of insulation
When moisture is trapped in an existing roof, it can lead to serious concerns that include ineffective insulation, mold growth, and corrosion of the metal components, which can – in turn – compromise the integrity of a new roof overlay.
Assessing Your Current Roof
The roofing inspector will assess not only the structural integrity of your current roof but also of your building in relation to the roof. The additional weight of simply putting a new roof over the old one could exceed the structure’s load-bearing capacity, which translates to a safety risk.
Considering the Kind of Overlay Used
The kind of commercial roofing system that you’re considering as a roof overlay is another critical piece of the puzzle. Generally, lightweight membranes are better suited to this kind of project than metal or built-up roofing would be. The kind of overlay you choose will affect your commercial roof’s maintenance requirements and its long-term performance.
Potential Concerns to Keep in Mind
The roofing pros you work with will help you determine if an overlay is the right way to go for you. Some of the potential concerns to consider include the following:
- Any undetected moisture issues can lead to premature deterioration of your new roof.
- The warranty on a roof overlay may be limited in comparison to what it would be for a complete replacement.
- If the overlay results in problems, the cost of replacement is very likely to include the cost of removing both your new roofing system and the one you laid it over.
