One Contractor for Every Kind of Roof in Blaine
Blaine’s commercial buildings along Highway 65 and I-35W ask a lot of their roofs. Retail and office roofs are wide and nearly flat, dotted with rooftop units whose curbs and flashing are the first places water gets in. Warehouses carry acres of membrane where a single clogged drain can pond water for days. Apartment and townhome buildings add pitched roofs, gutters, and dozens of tenants who notice every leak.
That mix calls for more than one answer. We restore low-slope roofs that still have life in them, replace the ones that don’t, and install complete Owens Corning systems on pitched buildings as an Owens Corning Platinum Preferred Contractor. Our crews are based a short drive north in East Bethel, so a Blaine roof never waits long for someone to look at it.
What We Handle on Blaine Commercial Roofs
Most of our Blaine work falls into four kinds of jobs. Each one gets the same project managers and installers as our Minnesota commercial roofing team, scaled to the size of the building.
Repairs That Target the Source
A leak on a flat roof rarely shows up directly under its cause, so we follow the water back to the curb, seam, drain, or penetration where it started. We fix that spot, document it with photos, and tell you honestly whether the rest of the roof has years left or is close to the end.
Complete Roof Replacement
When the membrane or deck is past saving, we remove the old system, fix the structure below it, and put down a new roof designed for the building’s size and drainage. Large projects are phased so parking lots, loading docks, and entrances stay usable while the crew moves across the roof.
Silicone Coatings for Wide Flat Roofs
Many Blaine retail and warehouse roofs are worn on the surface but still solid underneath. A silicone coating seals the whole roof in one continuous layer, stands up to the ponding water common on wide, nearly flat roofs, and goes on without a tear-off, so stores and loading docks keep running.
Planned Maintenance
Spring and fall visits clear drains and gutters, reseal flashing around rooftop units, and flag worn areas before they turn into interior damage. Each visit ends with a photo report, so you can plan repairs into next year’s budget instead of reacting to a leak.
Is Owens Corning the Best Shingle for Your Building?
Townhome buildings, churches, and smaller offices across Blaine tend to have pitched roofs, and those are roofed with a full Owens Corning shingle system. Owens Corning is an American manufacturer with a shingle plant in Minneapolis, just down the road from Blaine, so your roof comes off a Minnesota production line. You can check our Owens Corning certification directly with the manufacturer, including the “Top of the House” training behind every install.
Wind Resistance You Can Specify
Owens Corning builds its Duration® Series around patented SureNail® Technology, the first and only engineered woven-fabric nailing strip on the front of a shingle, placed right where wind tends to lift shingles first. Duration® shingles are designed to resist winds up to 130 mph, which gives a property manager a clear number to point to when comparing bids.
Decades of Roofing Firsts
Owens Corning was the pioneer behind the fiberglass shingle and has been making roofing products for more than 70 years. Because it manufactures both the asphalt and the fiberglass mat inside its shingles, it can keep quality steady and product available. It has also won the Women’s Choice Award as America’s Most Recommended roofing brand for eight consecutive years.
Class 4 Options for Hail Claims
After a hail loss, many owners want a roof that stands up better to the next storm. Duration STORM and Duration FLEX meet UL 2218 Class 4, the top impact classification for shingles. Before choosing, ask your commercial insurer whether it recognizes Class 4 on your policy.
Balanced Airflow Under the Roof
A shingle roof only lasts as long as the attic beneath it allows. “Top of the House” training spans everything below the shingles, from underlayment and eave ice protection to balanced intake and exhaust vents, which together keep heat and moisture from cooking the deck in summer or feeding ice dams in winter.
Warranty terms for commercial and multi-family buildings are not the same as residential ones, so your property’s coverage goes in writing before you commit.*
Our Process
Blaine takes longer to issue a commercial roofing permit than most of the cities we work in, so the schedule starts with the paperwork. Here’s how we keep your project on track from the first visit to the last inspection.
- Roof assessment. We walk the roof, check drains, seams, and rooftop units, and probe for wet insulation. Photos and a clear recommendation follow within days.
- Scope and proposal. The proposal spells out materials, square footage, and phasing, so you can plan around tenants, deliveries, and business hours.
- Permit filing. We submit through Blaine’s online roofing permit application, uploading plans and job specifications as PDFs. Review can take up to 15 business days and longer in the busy season, so we submit the day you sign off on the scope.
- Plans and inspections. Once the permit is paid, we pick up the approved plans at City Hall and keep them on site for every inspection. Blaine asks for three to four business days’ notice to schedule one, so we book ahead of each stage.
- Install and final inspection. Crews work to manufacturer specifications, the final inspection closes the permit, and you receive the permit record and warranty documents.
Do you own buildings outside Blaine, too? The same team covers other cities in our service area, so one project manager can handle your whole portfolio.
After a Storm Hits Your Property
A storm can damage a commercial roof in ways nobody sees from the lot: bruised membrane, cracked flashing on rooftop units, dented metal, or shingles that lost their seal. Catching it early keeps a small repair from becoming an interior loss.
We inspect the full roof, record the damage with dated photos and measurements, and can be on site when your adjuster visits. What the policy pays is your insurer’s decision, and we don’t make promises about it. You can read more about our insurance claim assistance process.

Frequently Asked Questions
How long does a commercial roofing permit take in Blaine?
The city allows up to 15 business days for review, and it can run longer during the busy construction months. We build that time into the schedule and file it as soon as the scope is approved.
How far ahead do inspections need to be scheduled?
Blaine asks for three to four business days’ notice. We schedule each inspection ahead of time so the crew isn’t left waiting on a sign-off.
Can you reroof an apartment building while tenants are living there?
Yes. We phase the work building by building, give managers notice to share with residents, and clear walkways and parking before the crew leaves each evening.
Is restoration cheaper than replacing a flat roof?
Usually, when the deck is solid and the insulation is dry. If moisture has spread through the roof, a coating or overlay would only trap it, and we’ll recommend replacement instead.
What should you budget for a commercial roof in Blaine?
Roof size, the system, drainage work, and rooftop equipment drive most of the price. Pricing comes after we inspect, and our overview of roof replacement pricing in Minnesota explains the main factors.
