When designing roofing and waterproofing systems, the average manufacturer warranty is for 20 years - therefore, you want your roof to last 20 years.

Yet, there are numerous organizations that don’t spend the minimal time and money upfront to make sure that their roofs last. Roofs are expensive - you want them to last for as long as your warranty exists. And ideally, you want them to last even longer.

Here, we take a look at what it can cost if you do minimal roof maintenance vs. an ideal amount of maintenance over the course of your building’s lifetime (we assume a 50 year period). We’ve adjusted for inflation over that time period and we look at different maintenance cost scenarios versus the potential financial benefits.

For reference, we have provided this roof cost replacement cost that adjusts for a 2% annual rate of inflation over the 50 year period (chart above). As you can see, what was an original roof construction cost of $1,000,000 balloons to $2,638,812 in Year 50.
