Like all roofing systems, commercial roofs are prone to wear and tear over time. When it becomes increasingly more evident that a commercial roof can no longer function properly, it’s time to consider other options. 

A total roof replacement can be an expensive process. One option to consider to bring a commercial roof back to watertight conditions under warranty is commercial roof restoration. This involves restoring the existing roof, which is cost-efficient and requires fewer materials. But how can you know if restoration is an option? Consider these important questions.

What Percentage of the Roof Is Damaged or In Need of Repair?

When considering roof restoration over total replacement, look at the overall damage to the roofing system. First, consider what percentage of the insulation is wet. Next, look at the percentage of scrim that is exposed and fasteners that are backing out. Last, and possibly most importantly, it is necessary to consider what percentage of the roof has ponding water and if there is a sloping issue for the existing roof. 

If the damage is within an acceptable and fixable range, then it could be a good idea to consider restoration over total replacement.  

Roofing Systems

Another consideration to keep in mind when debating replacement over restoration is how many roofing systems an existing commercial roof has. Commercial roofing companies can lay new roofing systems over existing ones only so many times before there is compromise. A commercial roofer will need to look at how many systems a commercial building has to determine if roof repair or replacement is the better option.

Metal Roofing

There are other factors to consider for metal roof replacement. For example, note whether there is an aluminized coating on metal roofing. Also, note rusting or damage to metal roofing that could make it unsafe to walk on. The determining factors for replacing metal roofing may be slightly different but are still important to keep in mind for the safest and most cost-efficient solution.
