Commercial Roof Replacement Services in Minnesota
Allweather Roof provides commercial roof replacement services for warehouses, manufacturing facilities, healthcare buildings, schools, office complexes, retail centers, and government facilities throughout Minnesota. Our team specializes in helping property owners replace aging roofing systems while maximizing long-term performance, energy efficiency, and return on investment.
Commercial Roof Replacement Solutions
Commercial roof replacement is the process of removing and replacing an aging, damaged, or failing roofing system to restore long-term building protection, energy efficiency, and performance. For many commercial property owners, roof replacement becomes the most cost-effective solution when recurring repairs, ongoing leaks, or extensive roof deterioration begin to impact building operations and maintenance budgets.
Over time, every commercial roofing system reaches the end of its useful life. Exposure to Minnesota’s harsh weather conditions, temperature fluctuations, UV radiation, moisture, and years of wear can gradually reduce a roof’s ability to protect a building. When roofing issues become more frequent or widespread, replacing the roof may provide greater long-term value than continuing to invest in repairs.
When Is Commercial Roof Replacement Necessary?
Commercial roof replacement may be recommended when:
Roof leaks continue to occur despite repeated repairs
Large sections of the roofing system show signs of deterioration
Ponding water regularly accumulates on the roof surface
Flashing, seams, or roof components have experienced widespread failure
Storm damage has compromised the roof's performance
The roofing system has reached the end of its expected lifespan
Repair costs continue to increase year after year
A professional roof assessment can help determine whether repair or replacement is the most practical solution for your building.
Benefits of Commercial Roof Replacement
Investing in a new commercial roofing system provides several long-term advantages:
Improved protection against leaks and weather-related damage
Increased energy efficiency and lower operating costs
Reduced maintenance and repair expenses
Enhanced building value and asset protection
Improved occupant comfort and building performance
Greater reliability and long-term peace of mind
Access to modern roofing technologies and warranty options
A properly designed and installed commercial roof can help extend the life of your building while supporting your operational and financial goals.
Commercial Roof Repair vs. Roof Replacement
One of the most common questions property owners ask is whether their roof should be repaired or replaced.
Roof repair is often the right solution when damage is localized and the roofing system remains in otherwise good condition. Roof replacement is typically recommended when damage is widespread, the roof has reached the end of its lifespan, or ongoing repairs are no longer cost-effective.
At Allweather Roof, our team performs a thorough roof evaluation to identify the condition of your roofing system and provide honest recommendations based on your building’s needs, budget, and long-term objectives. Our goal is to help you make an informed decision that delivers the greatest value for your property.

Built Up Roofing in Minneapolis, MN
What is Built Up Roofing?
It is made up of multi-layers of asphalt and fiberglass felts to provide a durable roofing membrane. BUR roofs consist of multiple layers of bitumen (a sticky, black, and viscous material) alternated with reinforcing materials such as fiberglass or organic felts. The bitumen serves as a waterproofing agent, while the reinforcing materials add strength and stability to the roof system. These layers are typically installed over a rigid insulation board to enhance energy efficiency and provide additional thermal protection.
Installation Process
Advantages of Built Up Roofing
Built up roofing is a popular roofing system because of several reasons. They are known for exceptional durability and longevity. It consists of multiple layers of asphalt and reinforcing materials, such as fiberglass or organic felts, which are hot-applied and then topped with a protective layer of gravel or a reflective coating. This multi-layered construction provides excellent resistance against weather elements, including UV rays, hail, and wind.
The expected lifespan of a built up roofing (BUR) system is typically 20-30 years with proper maintenance in lieu of 25-40 years. However, regular maintenance is necessary to ensure its longevity. The durability of a BUR roof is influenced by its design and installation quality. Each layer of the built up roofing, known as plies, contributes approximately five years to the overall lifespan of the roof. Consequently, incorporating more layers increases the roof’s longevity.
With Minnesota’s significant rainfall and occasional storms, effective waterproofing is crucial to prevent water infiltration and damage to commercial buildings. Built up roofing, with its multiple layers of bitumen, creates a seamless, watertight barrier, reducing the risk of leaks and water damage. This is especially important for flat or low-slope roofs commonly found in commercial buildings.
Disadvantages of Built Up Roofing
Due to the increased cost of oil, asphalt built up roofs have become the most expensive roofing system to install. Asphalt is a crucial component in the manufacturing of built up roofs. It serves as the waterproofing and weatherproofing material that provides protection against the elements. However, asphalt is derived from petroleum, which means its price is closely tied to the cost of oil. As the price of oil rises, the cost of producing asphalt increases as well.

What is PVC-KEE roofing?
PVC-KEE roofing is a type of single-ply roofing system commonly used in commercial and industrial buildings. It stands for Polyvinyl Chloride – Ketone Ethylene Ester, which refers to the materials used to create the roofing membrane.
PVC-KEE roofs consist of a single layer of PVC membrane reinforced with KEE, a type of thermoplastic elastomer. This combination enhances the membrane’s flexibility, strength, and resistance to UV radiation chemicals, and weathering.
Installation Process
Advantages of PVC-KEE
PVC-KEE roofing is inherently fire resistant and typically meets or exceeds fire safety standards. It has a high ignition temperature and is self-extinguishing, meaning it will not support combustion once the source of ignition is removed. PVC-KEE roofing also requires minimal maintenance throughout its lifespan. It is resistant to mold, mildew, and algae growth, which reduces the need for regular cleaning and maintenance. Routine inspections and occasional cleaning are typically efficient to keep the roof in good condition.
Disadvantages of PVC-KEE
PVC-KEE roofing materials can expand and contract with temperature variations. This characteristic is known as thermal movement. While PVC-KEE roofing is designed to accommodate these movements, proper installation techniques and attention to detail are necessary to prevent issues such as buckling, warping, or stress on the roof seams.

What is Sheet Metal roofing?
One primary purpose of architectural sheet metal at the perimeter of flat roofs is to create a seamless transition between the roof and the building’s exterior walls. It serves as a protective barrier against the elements, preventing water infiltration and ensuring the longevity of the roof. By securely sealing the edges, it helps maintain the structural integrity of the building and guards against potential damage caused by wind, rain, snow, or other environmental factors.
Installation Process
Advantages of Sheet Metal Roofing
Architectural sheet metal is a versatile and beneficial material when used on the perimeter of commercial roofs. They are known for their exceptional durability and longevity. Architectural sheet metal can withstand harsh weather conditions, including high winds, heavy rains and snow. This durability ensures that the roof perimeter remains intact and provides long-lasting protection. The primary function of the roof perimeter is to channel water away from the building. Architectural sheet metal is an excellent choice for this purpose, as it is resistant to water penetration. It can be formed into various shapes, such as gutters, downspouts, and flashing, to efficiently manage water runoff and prevent water damage to the building.
Using architectural sheet metal on the perimeter of commercial roofs provides additional strength and structural support. It helps reinforce the roof’s edges and prevents sagging or deformation of the roofing material. This added strength is particularly important in areas prone to heavy snow loads or high wind pressure. Architectural sheet metals are also fire resistant. In the event of a fire, the metal does not burn, melt, or release toxic fumes, reducing the risk of spreading the fire and providing additional time for evacuation. Lastly, architectural sheet metal requires minimal maintenance compared to other roofing materials. It is resistant to corrosion, rust, and rot, reducing the need for frequent repairs or replacement.
Disadvantages of Sheet Metal Roofing
Architectural Sheet metal can be more expensive than other perimeter materials. The cost of the metal itself, as well as the specialized fabrication and installation processes, can increase overall project expenses. Metal roofs including architectural sheet metal, can transmit sound more readily compared to other materials. Rainfall, hail, or other sources of impact can generate louder noise levels, which may be disruptive or uncomfortable for occupants within the building. While architectural sheet metal is generally low maintenance, repairs or replacement may be more challenging and costly compare to other perimeter materials. If the metal is damaged, dented, or corroded, it may require professional expertise and specialized tools to restore and replace sections.
