Different roofs

What are the Differences Between Commercial and Residential Roofing?

Running a business and running a household are two very different things. There are different priorities, considerations, and responsibilities. The same is true for the upkeep of a commercial or residential building. Alpha 1 understands the differences because we have over 60 years of combined experience in the industry.


The design of residential and commercial roofs are typically unalike. This is the most obvious way these two categories diverge. What many people don’t understand is why. Large businesses typically have flat or low-grade slopes on their roofs.

There are a multitude of reasons for this. One is the cost. Commercial buildings tend to be quite large and flat roof is generally cheaper than a sloped one. They can be easier to maintain since they are easily accessible. However, there is a drawback when it comes to a flat roof, which is waterproofing. Sloped roofs are so good at repelling water down the sides that they don’t need special sealants. The need for a sealant is the main downside for a flat roof. Luckily leaks are easy to spot on a flat roof, so they can be repaired quickly.


Flat roofs can’t be seen too well from the ground. They don’t need to look as nice as a sloped roof. This also plays a part in the cost difference. Residential roofs cost more per square foot because the aesthetically pleasing materials cost more.
