Modified bitumen roofing has been the standard commercial flat roof system for Blaine's industrial and mid-size commercial buildings for decades. The multi-layer asphaltic construction provides redundant waterproofing that single-ply systems cannot match, and torch-applied installation creates a monolithic surface that performs well through Minnesota's freeze-thaw cycles.
Modified bitumen is particularly well-suited to reroof applications on Blaine commercial buildings where the existing deck and substrate are already configured for a heavier system. Torch-applied installation creates a surface that is more forgiving of minor deck imperfections than single-ply systems and provides a redundancy layer that property managers on older buildings value for long-term leak resistance.

Torch-applied modified bitumen creates a monolithic asphaltic surface that is highly resistant to water infiltration and particularly forgiving of the minor deck movement that occurs in Blaine commercial buildings through Minnesota's seasonal temperature swings.
Cold-applied and self-adhering modified bitumen configurations provide alternatives where torch-applied methods are restricted by building occupancy or construction type. We match the installation method to the building's requirements without compromising the multi-layer waterproofing performance that makes modified bitumen a reliable choice for Blaine commercial applications.
Modified bitumen's multi-layer construction means water must penetrate through at least two complete asphaltic layers to reach the roof deck — a redundancy that single-ply membrane systems cannot provide. This is why modified bitumen remains the preferred choice for high-value Blaine commercial properties where leak events are not an acceptable operational risk.

Our commercial roofing service area extends from Blaine throughout the northwest Ramsey County corridor, including Shoreview's commercial corridors along Highway 96, Arden Hills's dense industrial and corporate campus zones near I-694, and Mounds View's Highway 10 commercial strip. Each market presents distinct roofing challenges — from the flat industrial roofs of Arden Hills business parks to the institutional structures in Shoreview and the mid-size commercial stock in Mounds View. We bring the same Anoka and Ramsey County regulatory familiarity and membrane expertise to every market we serve.
Proudly serving Blaine, Shoreview, Arden Hills, Mounds View,
Blaine's commercial properties — from the industrial corridors along Highway 65 to the institutional structures near the National Sports Center campus — require roofing systems engineered for Minnesota's freeze-thaw cycles, hail seasons, and snow load demands. We offer the full range of commercial flat roofing services for Anoka County property owners and facility managers.
Frequently Asked Questions
Commercial Roofing can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
Most commercial flat roofs in Minnesota last 15 to 25 years depending on membrane type, installation quality, and how consistently the roof is inspected through freeze-thaw cycles and heavy snowfall seasons.
TPO is generally the top choice for new commercial flat roofs in Blaine and Anoka County. Its heat-welded seams, UV reflectivity, and performance through Minnesota freeze-thaw cycles make it the most reliable option for most commercial applications.
Minnesota commercial property owners should schedule professional roof inspections twice a year — once before winter to identify vulnerabilities before ice loading, and once in spring to document any damage caused by ice damming or freeze-thaw membrane stress.
Anoka County commercial roofing projects typically require a building permit issued through the city or county permitting office. Full replacements almost always require permits. We handle the permitting process on all qualifying projects as part of our service scope.
Commercial hail damage claims in Minnesota must be documented thoroughly before an adjuster arrives. This means photos of impact marks on membrane, metal edging, and HVAC equipment. We provide professional storm damage assessments that meet Anoka County carrier documentation requirements.
A commercial roof coating can extend flat roof life by 10 or more years at a fraction of replacement cost. Silicone and acrylic coatings qualify for Xcel Energy cool roof rebates in Minnesota, making them a highly cost-effective option for qualifying commercial properties in Blaine.
Modified bitumen performs reliably in Minnesota cold because its multi-layer construction provides redundant waterproofing and the bitumen compound remains stable through freeze-thaw cycles. It is commonly used on reroof projects involving older Blaine commercial structures where the deck is already configured for layered systems.
Modified bitumen is installed using one of three methods: torch-applied, where a propane torch melts the membrane underside for adhesion; cold-applied, using bonding adhesive; or self-adhering, using a factory-applied adhesive backing. Torch-applied is the most common method for commercial reroof applications in Blaine.
Modified bitumen commercial systems typically last 20 to 30 years with proper installation and regular maintenance. Torch-applied systems on good deck conditions are on the higher end of that range. Systems that are not maintained — particularly drainage and seam inspection — can fail significantly earlier through Minnesota freeze-thaw cycling.
Modified bitumen is a multi-layer asphaltic system installed in overlapping laps, providing layered waterproofing redundancy. TPO is a single-ply thermoplastic membrane with heat-welded seams. Modified bitumen is heavier and better suited to reroof projects with adequate deck loading. TPO is lighter, faster to install, and more energy efficient.

We manage three office buildings in Blaine and have worked with a lot of roofing contractors over the years. The difference here is they actually understand commercial flat roofs — TPO specifications, drainage slope requirements, Anoka County permitting. They replaced the membrane on our largest building and handled the whole permit process. No surprises, clean work.

After last spring's hail storm we had significant damage to our warehouse roof on the Highway 65 corridor. They came out within 24 hours, documented everything the insurance adjuster needed, and had a full TPO replacement scope ready before any other contractor even returned our call. The claim was approved and the job was done inside three weeks.

We had been getting quotes for replacing a modified bitumen roof on our Blaine commercial property that were all over the map. These guys inspected it, showed us exactly what sections needed replacement versus what could be maintained, and gave us a phased plan that fit our capital budget. That kind of honest assessment is rare in this industry.
