If you have ever wondered what makes flat roofs so much different than standard pitch roofs, our flat roof blog category will be a good place to start reading.
In our flat roof education category, you will find the number of topics related to flat roof repair, replacement, installation, and maintenance. Due to the fact that low-slope roofs are susceptible to problems that are intrinsic only two slopes below 3:12, (3 on 12) they require different methods, materials, and maintenance than standard pitched roofs, therefore, they belong in their own category.
Here are examples of some of our most informative flat roof educational articles:

How to Deal with Flat Roof Repairs
If you want a quick lesson to get you up to speed on the topic,, flat roofs are more susceptible to leaks because of the force of gravity caused by their low pitch. Quite simply,, the pitch of a roof affects the force of gravity because of its horizontal or vertical axis.
When a roof is more horizontal than it is vertical (a.k.a. “Flatter”) the force of gravity instead of pulling the water down off of your roof tries to pull the water through the roof so it sits on the roof longer and with more force… And that causes more leaks.

Infrared roof leak detection and thermal imaging, a non-invasive technology, finds moisture damage in flat roofs by spotting temperature difference that often signals trapped moisture under the roof membrane. Wet insulation holds heat longer than dry areas, so it shows up as warmer (or sometimes cooler) “blotches” on a thermal image. A trained technician maps…
Electronic leak detection finds holes in a roofing membrane by using a controlled electrical field. When there’s a membrane breach, electricity follows the path of least resistance, often through moisture, to the conductive deck or a grounded return line. The technician tracks that signal and marks the exact leak location, so repairs target the true…
After harsh Minnesota winters that batter roofing materials with heavy snow and ice, focus your spring roof inspection on vulnerable spots like drains and scuppers, seams and flashing, roof edges, and rooftop penetrations (HVAC curbs, vents, skylights). Once the snow melts, check for ponding water, split sealant, loose coping, punctures from snow removal, and new…
If you’re asking, what are the cons of TPO roofing before selecting a single-ply membrane. TPO can look attractive on paper, but leakage and premature aging sometimes appear sooner than expected. This article previews common failure modes: seam problems, heat-driven cap-layer loss, and surface issues, so you can spot trouble and act quickly. For property…
Choosing between EPDM and TPO comes down to priorities: durability in cold weather and long life, or reflectivity and energy savings. EPDM generally gives a proven, long-lasting rubber membrane at lower upfront cost, and it handles Minnesota winters well. TPO offers a heat-welded thermoplastic membrane that can cut rooftop heat gain and lower cooling costs…
Hail damage on a commercial flat roof counts when hail creates a puncture, tear, split, cracked seam, displaced flashing, or bruising that weakens the membrane and shortens roof life. Even if you don’t see an active leak, commercial flat roof hail damage can still be “real” damage when it compromises waterproofing, insulation, or critical details…
Short answer: Wind uplift damage on flat roofs often shows up as lifted membrane edges, curling seams, “bubbles” or billowing areas, wrinkles that weren’t there before, and loose or missing edge metal. On gravel roofs, you may see displaced ballast and exposed membrane. Damage usually concentrates at corners, perimeters, and around rooftop units, then turns…
Modified bitumen hail damage usually shows up as granule loss (dark asphalt spots), shallow dents, bruised or “soft” areas, split seams, and punctures near laps, flashings, and drains. In Minnesota, freeze and thaw can turn small hits into leaks later. Photograph suspect areas with a coin or ruler for scale, then schedule a professional inspection…
What maintenance should be done on a roof includes routine inspections, clearing drains and debris, checking seams and flashing, fixing small punctures fast, and documenting all work. How do you maintain a commercial roof? Set a schedule (at least spring and fall), add post-storm checks, manage snow load, and address freeze-thaw damage early so you…
When property owners invest in a flat roofing system, one of the first questions they ask is how long it will actually last. For commercial buildings across Minnesota, TPO roofing lifespan typically ranges from 20 to 30 years, but that number depends heavily on factors most installers won’t discuss upfront. Understanding what drives those numbers…
Hail damage on EPDM roofs in Minnesota often looks subtle at first: small dimples, scuffs, or “bruised” spots in the rubber membrane. The bigger red flags usually show up at seams, flashings, and rooftop penetrations, where hail impact and temperature swings can open tiny pathways for water. If drains back up or metal edges get…
