What Affects The Cost Of A Commercial Roofing System?

Perhaps your roof is leaking, and you know it is ancient. It is time to call commercial roofing contractors to get a brand-new roofing system. But what type of roof should you get? Like the majority of building owners, you would like the one that costs the least. The problem is there are a lot of variables when it comes to cost, such as:

  1. Different roofing systems cost different
  2. Scope of work or roof details
  3. How simple is it to access the roof
  4. How much roof preparation is required
  5. How much R-value is desired
  6. How long of a warranty is desired
  7. How much wet insulation does your current roof have
  8. How far away are you from the commercial roofing company
  9. Current material prices versus previous material costs

The number of penetrations

A penetration is a skylight, pipe, HVAC unit, exhaust, drain, or anything that comes through the roof. These add costs to traditional roofing systems such as TPO for the reason that the sheets need to be cut. Sealants, boots, and adhesives also need to be utilized to make penetrations watertight.

Since spray foam and roof coating systems are fluid-applied, the installation process is not interrupted. As a result, the number of penetrations only adds costs to single-ply and metal roofs.

How far away are you from the roofing contractor?

The further away you are from the roofer, the more gas that is needed to haul equipment, materials, and labor to the job site. This does not mean automatically selecting the roofing company closest to you. A quality roof installation is much more critical. It is more advantageous to shell out more for a roofer far away, knowing the job will get done right.

The headaches involved with leaking, service calls, repairs, warranty work, etc., can all be erased by opting for a contractor that knows what they are doing.

How much wet insulation does your current roof have?

No roof should be installed over wet insulation. If you do not get rid of it, blisters can take place when that trapped water gets warm over the summer and tries to evaporate through the roof. Water under the membrane can freeze in the winter and expand an existing water entry point when it thaws. A roofing company will pull core samples and/or carry out an infrared inspection to find out the presence of wet insulation.

How much R-value is desired?

This goes along with warranty durations. The more R-value that is desired, the more materials that will be needed. On metal and single-ply roofs, the most common way to increase R-value is to install a polyiso board. Polyiso board has an R-value of 5.5 per inch of thickness. If you need to hit a minimum R-value, because by code, it is a new construction project, you will likely need to hit a minimum of an R-25. In this case, you would need more than 4 inches of polyiso board to be code compliant.
