Flat roof leaks, found at the source and fixed for good.
Flat roof leaks rarely show up where the water gets in. We use thermal imaging and moisture meters to find the real source, fix it, and keep your building dry until replacement actually makes sense.

What homeowners say.
As a property manager, I've worked with many other companies but their professionalism, timeliness, service and everything was great! I will keep using them.
Our new roof looks fantastic, and more importantly, we no longer have to worry about leaks! They are reliable, trustworthy, and deliver top-notch quality.
Mike came to do an assessment. He caught concerns others had missed. He was professional and polite but very kind. I would recommend him 100%.
PVC, TPO, EPDM or modified bitumen?
There's no single best flat roof. Here's how the main systems compare on Minnesota buildings.
| System | Seams | Best fit | Watch out for |
|---|---|---|---|
| PVC (Duro-Last) | Heat-welded; up to 85% welded in the factory | Restaurants, grocery, dealerships, schools, roofs with lots of rooftop units | Higher upfront cost than basic TPO |
| TPO | Heat-welded on the roof | Budget-conscious warehouses and multi-family roofs wanting a white surface | Less grease resistance than PVC; quality varies by manufacturer |
| EPDM rubber | Taped or glued | Simple roofs with few penetrations; strong cold-weather flexibility | Seam tape and flashings dry out and peel with age; black surface runs hot |
| Modified bitumen | Torched or cold-applied laps | Small roofs, porches, heavy foot traffic | More seams; torch-applied work needs strict fire precautions |
Leaks, ponding, blisters, ice.

Straight answers.
Why can't anyone find my flat roof leak?
Water on a flat roof can travel under the membrane or along the deck before it drips inside, so the stain is often far from the entry point. Thermal imaging and moisture readings help us trace it to the source.
Should I coat or replace my flat roof?
Coatings work well on roofs that are mostly dry and structurally sound. If there's widespread wet insulation or membrane failure, replacement is usually the better investment. We'll show you the readings.
Which is better: PVC, TPO or EPDM?
Each has strengths. PVC like Duro-Last has heat-welded seams and strong chemical resistance, TPO is cost-effective and reflective, and EPDM is flexible and proven in cold climates. We recommend based on your building and budget.
Can a new commercial roof qualify for Section 179?
It can for nonresidential buildings. See our Section 179 page and talk to your CPA.
