Commercial Roofing Types And Their Benefits

September 20, 2021

Flat roof systems are the most commonly used in commercial roofing and in North America because they work well for many applications including: industrial buildings such as warehouses or workshops; retail stores with large loading bays that need to remain watertight during heavy use periods when vehicle traffic is heaviest; office spaces where aesthetics aren't a huge consideration since there's no snow removal needed at all times of the year.

Types of Roofs:

Flat Roofs:

People have been using flat roofs on commercial buildings for 90 years. Before, most of the time people used pitched roofs to cover their structures but now more and more architects are designing with a flatter look in mind- we think this is because they're easier to maintain and cut down costs!

In the 1920s, flat roofs became a symbol of commerce and modernity. Before then, pitched roofs were more common for commercial structures. Flat commercial roofing in Las Vegas systems offer many benefits to building owners and roofing contractors throughout the world today.

Advantages of Flat Roofs:

Cost effective:

Commercial flat roofs can be significantly more cost effective to build than pitched roofs or steep slope roofs because they require less material due to the fewer square feet of area needing coverage. You can learn more here.

Easier installation:

They are easier and quicker [to] install, which can translate into a significant savings for the building owner. This also affects how easy it is for your next commercial roof repair if you have one - owners have many types of flat roofing materials and membranes available including rubber rolled roofing, EPDM membrane systems (which typically last 20+ years), PVC sheet products, TPO single ply system options.


While there are many different color choices to choose from with roofing membranes, however white is the most common choice for building owners.

This can help reduce energy waste due to its reflective properties.


Air conditioners can be moved from the ground to the roof and solar panels/ satellite dishes are easier on flat roofs than pitched ones which makes them less visible when looking at it in person or through images like Google Maps images etc.

Easy Maintenance:

Maintenance and drain cleaning is also easier on flat roofs since workmen walk around easily regardless of weather conditions making this job simpler compared if they were dealing with a steeply inclined surface instead of something close enough level that you could lay down without any issues whatsoever.

Low-sloped Roofs:

Low-sloped roofs are found on warehouses, apartment buildings and other industrial structures. These slanted rooftops appear to be flat but actually have a slight pitch. Whether you're looking to build a new facility or are considering building renovation for your current commercial space, flat roofs provide some of the most cost-effective options available. From traditional metal and modified bitumen & buildup materials to PVC, TPO (thermoplastic polyolefin), and EPDM (ethylene propylene diene monomer) membranes; this roofing type is an attractive choice whether on its own or as part of high-performance system incorporating insulation layers below.


Lesser Material Is Used:

A design in roofing geometry that makes it easier for builders to complete roofs, low-sloped or flat roofs are common with modern architecture. The pitch of the slope causes water runoff and directs this flow into drain pipes on either side.

The area covered by these types of roofs is less than higher pitched slanted rooftops requiring fewer square feet per covering material used.

Easier Installation:

There's less chance that the building owner will need to call repairmen since a slight pitch does not allow for standing water or puddling.

Cracked, peeling paint and stained shingles are avoided because of this fact as well.

Better Appearance:

Commercial buildings with roofs installed on low-sloped commercial roofs have air conditioners, solar panels and satellite dishes easy to install along with being maintained making it more appealing than roofs which have higher pitches in their slant.

Commercial Pitched Roofs

While pitched roofs are generally seen in residential homes more than commercial buildings, they still commonly accompany flat and low-sloped rooftops.

Traditional pitched roofs were made from materials that could be found in the local environment, like stone and clay. The traditional construction method involved covering a sloping roof with tiles or shingles to keep out water.


Great In Letting Go of Snow And Water:

The main positive aspect of pitched roofs is that the increased slope provides greater runoff for water and snow, so they are less likely to accumulate.

Lesser Repairs:

This means you will have a reduced need for repairs over time compared to flatter structures with little inclination.

Commercial Metal Retrofit Roofing:

Your existing metal roof will be protected from further corrosion with a single-ply membrane system that provides insulation value, avoiding the high cost of removing your old tiles or shingles for replacement.

This process also adds additional protection against not only water but fire as well, since these systems are built using noncombustible material such as aluminum oxide fiberglass batting between two layers of reinforced polymer laminate (PVC). A gasket around each seam ensures strength and security over time while tapered overlapping seams provide easy installation across irregular surfaces like dormers and valleys without cutting or fastening nails directly into the substrate below.


Cost effective:

The biggest benefit of using metal roofing is the cost. It may seem counterintuitive, but not only does it increase your house's lifespan by many years--while also protecting against natural disasters such as ice storms and tornadoes--it costs less than having a regular old-fashioned aluminum one replaced!


Retrofitting a roof is an eco-friendly way to save on energy costs and reduce landfill waste. By not taking the roof apart, this saves materials from being scrapped or damaged, making it more appealing for environmentally conscious homeowners who want to do their part in preserving nature.

Regulates temperature:

When you retrofit your roof to be more eco-friendly, you are taking advantage of reusing the current insulation in addition to additional insulation from an exterior membrane. This can help save on energy costs and keep building temperature regulated.
