The Main Difference Between Residential and Commercial Roofs

While there’s a variety of roofing options available, it’s important to know about the distinctive features of each material. Some systems are suitable for homes while others are ideal for business establishments. Koziatek Contracting, Inc., the area’s premier roofing company, explains the distinguishing features of residential and commercial roofs.

The Main Difference Between Residential and Commercial Roofs


One of the primary differences between residential and commercial roofing systems lies in the slope. Roofs installed in commercial buildings are either completely flat or tilted slightly. Flat roofs are easier to build on large structures.

Residential roofing systems, on the other hand, aren’t limited to the no-slope style. They are more flexible when it comes to design, as they will cover a smaller area compared to commercial roofs. Homeowners can choose from several options, from the A-frame to the butterfly roof.


The way residential and commercial roofing systems deteriorate differ entirely. Roofs installed over homes often deal with curling and granule accumulation in the gutters. On the other hand, commercial roofs typically encounter punctures, ponding and clogging.

Material Selection

Each roof design calls for the right roofing material. Residential properties can benefit from asphalt shingles, tile, metal and slate roofing. These materials focus on performance and aesthetics. Meanwhile, commercial structures can take advantage of the heavy duty characteristics of modified bitumen, EPDM (ethylene propylene diene monomer), PVC/TPO single-ply membrane and metal roofing. These products are highly resistant — though not immune — to harsh weather and chemical exposure.
