5 Factors That Can Affect the Cost of a Commercial Roof Replacement

Ascent RoofingUncategorized

What are the five most affecting factors that tie into the cost of replacing your commercial roof? We’ve compiled several things to remember when planning a roof replacement – whether your commercial building is one or ten stories tall.

1. Square Footage

First and foremost, the size of your roof is directly proportional to how much it will cost to replace it. Not only is the buildings’ footprint a variable in price point, but the roof style can also influence how much you’ll pay. For example, a sloped roof means that you have to use different, more costly materials, and it also means that you will have a larger surface area to cover. However, depending on how long you want your roof to last, a pitched roof can be a significant long-term investment, outlasting its warranty in some cases.

2. Building Materials

Speaking of material choices, you have several options to consider. Flat commercial roofs can be replaced with single-ply systems such as TPO, EPDM, and PVC. Each of these materials has its pros and cons:

  • TPO has the shortest lifespan, but it will reflect heat, resist mold, and withstand harsh environmental conditions throughout its lifecycle.
  • EPDM is easy to install and is the lowest cost per square foot. It can lower your air conditioning costs when installed in white but will become fragile at the end of its 20-year lifespan.
  • PVC is an excellent choice for eco-friendly options and is fire-resistant (a huge win in California). Your PVC roof can last up to 30 years.

Asphalt-based built-up roofing (BUR) is commonly used if your roof has a pitch. It can often outlive its warranty, lasting for 50 years or more, but costs much more to install.

3. Number of Stories

The taller your building, the more difficult the roof is to access. Getting materials on top of a one story building vs. hauling everything up to the 10th story drastically impacts the amount of time your contractors will spend getting the roof redone. You also have to consider whether or not your site has the space to store materials or if daily transport will be the way to go.

4. Decking Quality

The decking underneath your roof is as important as the roofing material. Therefore, getting a thorough assessment of that decking is a critical factor in determining what needs to happen: can the decking be repaired, or will it need a complete overhaul too?

5. Meeting Current Building Codes

If your roof was originally installed in a time with less-strict building codes, that doesn’t mean your new roof will be put in without adhering to current coding requirements. Ensure that your contractor is up-to-date on the relevant codes and is licensed to abide by them.
