The 2024 Commercial Roofing Report from IBISWorld reported that the commercial roofing sector in the U.S. generated revenues of $14.2 billion, and significant growth in service demand was attributed to waterproofing technologies, which rose by 19%. Building owners are prioritizing roof longevity and energy efficiency, and waterproofing is now a necessity rather than a luxury. Businesses in Star, Idaho, cannot risk roof failures related to poor waterproofing because the potential for wide temperature swings and moisture accumulation can negatively impact them.
Waterproofing your commercial roofing in Star is one of our specialized areas of service at Bork Roofing, as we focus on modern waterproofing strategies. Most roofing contractors tend to stick with legacy waterproofing methods/formats, while we focus on working with modern materials, application methods, and routine maintenance programs that will preserve your investment for years to come.
Now, let’s cover some of the most tried-and-true methods you should consider when waterproofing your commercial roof.
Why Waterproofing is Important Now More Than Ever
Water infiltration is the single most damaging issue a commercial roof can be exposed to. Water may appear to be a slow-moving problem, but it doesn’t take much water, or even a very small penetrating leak, to compromise the structural integrity of the roof system.
An initial minor water-related issue can lead to tens of thousands of dollars worth of damage to your property, with attendant costs related to service disruption to your business, too.
Waterproofing is more than just a technique of applying a waterproofing membrane to the roof. Modern waterproofing is a strategic process that contemplates the slope of the roof for run-off water, waxing and waning climate patterns, how the building is designed in terms of the structural makeup of the materials used, and lastly, how the building is used.
Common Vulnerabilities in Commercial Roofing
Even the strongest roofing systems have weaknesses that are an invitation for water to intrude. Learning about the common weaknesses can assist in making better waterproofing solutions:
- Flashing and penetrations (vents, skylights, HVAC units)
- Seam overlap in membrane systems
- Drainage failures due to clogged scuppers or a slope that is poorly designed
- UV degradation that cracks or dries out the components
- Foot traffic in service areas like rooftop HVAC systems
If these vulnerabilities are not addressed, they can result in frequent repairs, decrease the building’s energy efficiencies, and even violations of the building code. This is one of the reasons why Star business owners are choosing to utilize preventative waterproofing methods in place of reactive repairs.
The Best Waterproofing Methods for Commercial Roofs
-
Liquid-Applied Membrane Systems
Liquid-applied redundancies are some of the most advanced waterproofing options in use today. These systems, such as polyurethane, silicone, or PMMA, can create a fully adhered, seamless layer that conforms to any pattern and detail of the roofing system. They are especially useful when dealing with complex penetrations or irregular geometric shapes of roofs.
Benefits:
- Provides seamless coverage with no seams or overlaps, which is where water usually enters
- Provides excellent UV resistance
- Cures quickly and provides minimal downtime for businesses
One of the advantages of these liquid-applied membranes is their ability to remain flexible in fluctuating temperatures, which is an ideal trait in Star’s variable, unique climate.
-
Single-Ply Roofing with Welded Seams
The most common commercial roofing in Star is single-ply systems such as TPO, PVC, and EPDM, but the real waterproofing force comes from heat-welded seams. While an adhesive is perhaps acceptable at low marketing value, it is not an acceptable solution for seams unless the seams are heat-welded to create monolithic, watertight connections.
Overview:
- Exceptional resistance against ponding water
- Longevity (20–30 years with maintenance)
- Lightweight and energy-efficient
When installed precisely and with an appropriate insulation underlay, single-ply membranes can be one of the most cost-efficient and durable waterproofing systems available.
-
Self-Adhering Waterproofing Sheets
Self-adhering systems are rolled membranes with adhesive underneath, usually in modified bitumen or rubberized asphalt. When installed properly, self-adhering membranes provide excellent water resistance and have very few seams to leak.
Best on:
- Low-slope roofs
- Retrofits when mechanical fastening cannot be installed
- Areas needing additional puncture resistance
As self-adhered membranes are adhered directly to the substrate, they typically have a reduced risk of wind uplift and moisture migration below the membrane.
-
Reinforced Bitumen with Cold Process Installation
Reinforced bitumen membranes are a traditional solution; however, they are significantly improved with modern cold process installation methods. Instead of roofing felts being fused together using hot tar, contractors are able to utilize cold adhesives to fully install roofing membranes, which eliminates odor, fire risk, and carbon footprint.
Benefits:
- Venturing in tight places is easier due to the flexibility in applying the products
- Options for multi-ply assembly to offer heightened durability
- High protection against mechanical damage from inappropriate activity on the rooftop
This method shows great promise for roofing services, where you are virtually re-roofing in Star. , where a maximum structural load is enforced and safety is critical.
-
Green Roofs with Built-In Waterproofing Layers
Although green roofs are rarely pursued solely for environmental benefits, they can be considered an advanced form of waterproofing as well. Underneath the soil and vegetation, there exists a multilayer waterproofing system along with a root barrier system. This system protects the building envelope from the soil and vegetation components.
Reasons to implement in Star:
- Helps regulate roof temperatures
- Better stormwater runoff
- Increases roof life due to UV delay
Green roofs can be more complicated but are designed to let the climate work for you and to provide long-term return on investment and sustainability for commercial properties.
Important Things to Think About When Flat Roofing in Star, Idaho
The climate of Star will have high exposure to UV, occasional hailstorms, and significant snow load in the winter. All of these elements contribute stress on roofing materials, adhesives, and seams. Your waterproofing system not only has to block water, it should withstand the expansion and contraction from thermal shock.
Also, with commercial and residential flat roofs in Star, there are often HVAC units, vents, solar panels, or skylights. Each of these can be a headache to waterproof. Simply slapping a waterproof membrane on and calling it good does not really address some of the nuances of the transitions and penetrations. Each needs to be caulked and expected to move with the dimensions of the waterproof membrane.
Because of that, it’s important to plan for preventive maintenance. At Bork Roofing, we not only offer repairs but will include thermal scans and moisture detection as part of our long-term service plans. We feel that proactive management of your roof system is a key means for good leak prevention.
What Most Contractors Don’t Even Talk About
A lot of roofing companies will tell you that they will “waterproof” your roof, but very few mention what that really means. Here are a few things that they’re not going to tell you:
- Not all membranes are the same: some coatings only act as a UV barrier and don’t withstand ponding water or foot traffic
- Slopes that are wrong kill waterproofing: a premium system will not work without the proper pitch/design on drainage
- Warranty ≠ Performance: a 20-year warranty does not mean the roof will be leak-free for 20 years unless the roof was maintained
- Cheap goods cost taxpayer dollars later: low-grade adhesives or thin membranes may only last a few seasons before they start to fail
At Bork Roofing, we don’t just fix roofs, we diagnose the problem and take details into consideration when deciding performance expectations in relation to the correct detail, not the easiest to put on and leave.
