Average Cost of Replacing a Roof in DuPage County, Illinois

If you are considering replacing the roof on your home or business in DuPage County but are concerned about the cost, you’re not alone. In fact, many home and business owners put off this job due to its relatively high cost, with the price of roofing services in Wood Dale and other DuPage County towns varying greatly.

However, it’s important to consider the ramifications of putting off roof replacement—over time, neglecting repairs can cause more damage in the building due to leaks, mold, and other issues.

It’s important to tend to problems with the roof sooner rather than later, and starting to plan for it now can help prevent shocking sticker prices and a scramble to find the funds later on.

Factors that Affect Roof Cost

There are a number of things that affect the cost of roof replacement in DuPage County, including size, pitch, damage, and materials used. It's important to pay close attention to each of these aspects if you want to accurately calculate how much DuPage roofing repair or installation services will cost. The roofing experts at Adept Construction will help ensure that you understand what your project will cost before getting started, with the experience needed to complete every project on time and without any undisclosed costs.

Roof Size and Installation Time

First and foremost is the roof’s size. Roofers typically charge per “roofing square.” A 10-by-10-foot area (100 square feet) is considered one roofing square, so if the roof is 2,000 square feet, it’s defined as 20 roofing squares.

Naturally, the size of the roof will determine the amount of time it will take to replace, as well as how much roofing material is needed. A larger roof could take many days of work to complete, and weather could further influence the amount of time it takes to complete the job. Unusually harsh weather could result in setbacks, which makes it important to consider what time of year you want to complete the installation. Getting a large roof replacement in the coldest months with the most snow could take the most time to complete, which could make the summertime more ideal for installation.


Another thing that affects the roof cost is the pitch, or slope. Some roofs have a high pitch, while others have nearly no slope—both factors can affect the cost.

Slopes are represented by ratios, with the first number representing the height and the second representing the length.

For instance, a 5:12 roof means that for every 12 inches it runs horizontally, it rises five inches vertically. Roofs with steeper slopes, for instance, don’t allow for materials to be stacked/stored on the roof and thus take longer to replace, and may require roofers to use extra safety harnesses and equipment, so the cost can be higher.

Pre-existing Damage Existing damage, such as water seepage, can also affect the cost—and the impairment may not be found until after the old roof is taken off.

This is another argument for replacing the roof sooner rather than later.

Composite Shingle Roof, Cedar Shingle Roof, Flat Roof, or Shingle Roofing

Types of roofing materials, of course, also affect the cost greatly.

For instance, a metal roof could be twice as expensive as asphalt shingles, and slate roofs can be even pricier—up to five times as expensive as asphalt shingles. Cost is typically dependent not only on the amount of work required to install, but also the lifespan of the materials. Consider whether asphalt or composite shingle, cedar shake, or flat roofing is right for your home or business.

The larger the roof, the higher the cost, of course, which can influence the decision to choose roofing materials that are less expensive for larger areas. You should also consider whether a larger roof will benefit from long-lasting materials that won't require frequent repairs to patches.
