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.

Storm damage to a roof refers to sudden, weather-related impacts that affect how the roof performs or protects the building. On commercial roofing systems, this can include hail damage (bruising or punctures), lifted seams, torn flashing, wind uplift, debris impact, and new leaks after rainfall. Damage caused by age, lack of maintenance, or normal wear…
You know your roof has hail damage when a recent storm is followed by random impact marks, dents on soft metals, bruising or punctures in the roofing surface, damaged flashing, or new interior leaks. On commercial buildings, the clearest signs often show up around seams, drains, rooftop units, and metal edges, not in one obvious…
Commercial roof leak detection on low-slope metal roofs works by tracing the leak from inside the building, mapping how water may travel, inspecting seams, fasteners, laps, flashings, and penetrations, then confirming the entry point with infrared, moisture testing, or controlled water tests. The goal is simple, find the true source, not the spot where water…
Yes, infrared scans can often find likely wet insulation on EPDM roofs by showing temperature differences between damp and dry areas, usually after sunset. Still, a scan is not final proof. The best practice is to confirm suspicious spots with a roof inspection, moisture testing, and a few small core samples. That distinction matters to…
Bathroom fan roof vent leaks usually show up as ceiling stains, drips at the fan grille, wet insulation, or rust around the roof cap. In Minnesota, snow, ice, and freeze-thaw cycles often crack flashing or sealant around the vent, so a small drip can point to a bigger roof issue fast. When This Applies This…
Commercial PVC roof hail damage is inspected by checking the interior, reviewing the storm, and then walking the roof in a grid. The inspector looks for punctures, split seams, cracked flashing, wet insulation, and rooftop unit damage, then documents each finding to decide between repair, section work, or replacement. When This Applies Who should use…
New roof hail damage usually looks clean, sharp, and recent, while old hail damage looks weathered, dirty, oxidized, or blended into the roof’s age. The best clues are the storm date, fresh exposed material, sharp impact edges, matching dents on metal components, and whether the roof shows new leaks or newly broken seams. When This…
You detect a built-up roof leak without core cuts by layering built-up roof leak detection methods, not by guessing. Start with interior leak mapping, inspect the roof surface, scan for trapped moisture with infrared, confirm wet areas with a moisture meter, and use electronic leak detection when the roof surface allows it. That usually narrows…
To detect a modified bitumen roof leak, inspect seams, flashings, blisters, splits, drains, and ponding areas, then confirm hidden moisture with infrared scanning, electronic testing, or small test cuts. Don’t trust the interior drip alone, because water often travels under the membrane before it shows inside. A ceiling stain is like smoke, not the fire….
Yes, in many cases you can detect a commercial roof leak detection issue without shutting down the building. The safest approach is to map interior signs, inspect the roof surface, use infrared moisture scanning, and confirm problem areas with low-voltage electronic testing. That keeps disruption low and helps crews target the real leak, not just…
Good flat roof leak detection starts inside the building, then moves to the roof surface, moisture mapping, and final confirmation testing. White coatings can hide small cracks, failed seams, and wet insulation under a clean-looking surface, so visual checks alone often miss the source. Infrared scans, electronic testing, and moisture probes usually give the clearest…
Short answer: You’ll suspect roof decking rot when your roof system shows ongoing moisture infiltration plus structural “softness.” Inside, watch for recurring ceiling stains, musty smells, or bubbling finishes. On the roof, look for ponding water, failing seams, or spongy areas that flex under safe, limited foot pressure. In Minnesota, freeze thaw cycles and Minnesota…
