Key Things That Affect The Cost Of Replacing Your Commercial Roof

A sturdy, well-maintained roof is integral to the structural integrity of any commercial building. However, when it comes time to replace it, the associated costs can be substantial.

This article sheds light on the main factors affecting the cost of commercial roof replacement, helping you easily navigate this complex process.

Layer Removal 

The layer removal process can significantly impact the cost of replacing your commercial roof. Essentially, if the old roofing material needs to be removed before installing the new one, this can add to the labor and disposal costs of the project. The complexity of the removal process largely depends on the type of existing roofing system and the number of layers that need to be removed.

For example, if your commercial building has a single-ply membrane roof like TPO or EPDM, the removal process might be relatively straightforward and less labor-intensive, thus less expensive.

However, if the building has a built-up roof (BUR), which consists of multiple layers of tar and gravel, the removal process can be more complex and time-consuming. This is because each layer has to be carefully stripped away, and the gravel need to be properly disposed of, both of which increase labor and disposal costs.

Moreover, local regulations may also affect the cost. Some regions have strict rules about roofing waste disposal, which could increase the cost if special disposal methods are required.

Additionally, if multiple layers of roofing material have been accumulated over time, some building codes may mandate their removal once a certain number of layers have been reached. This can add an unexpected expense to your roof replacement project.

Additional Components

Additional components of your commercial roof can influence the overall roof replacement cost. These components include features like skylights, chimneys, HVAC systems, and drainage systems. Each of these elements requires special attention during a roof replacement, adding to the complexity and cost of the project.

For instance, if your building has skylights or chimneys, these will need to be carefully worked around or temporarily removed during the roof replacement. This process can be labor-intensive and require specialized skills, increasing labor costs.

Similarly, HVAC systems located on the roof will need to be properly protected or temporarily relocated during the project. This requires additional labor and could also involve hiring HVAC specialists, further adding to the cost.

Drainage systems, too, play a significant role. Commercial roofs, especially flat roofs, require effective drainage systems to prevent water accumulation and subsequent damage. If your existing drainage system needs to be upgraded or replaced during the roof replacement, this will add to the overall cost.

Furthermore, any customizations or upgrades — such as installing more energy-efficient materials or adding green roofing elements — will also affect the final price. As such, you need to consider all these additional components when budgeting for a commercial roof replacement.
