Lakeville, Minnesota
Professional TPO Roofing in Lakeville, MN
Most of the low slope TPO work we do in Lakeville lands in Airlake Industrial Park, on wide single plane roofs over manufacturing and distribution buildings. Those roofs drain a long way to a few interior drains, and the membrane over them went down when the buildings did. Much of that corridor filled in through the late 1990s and 2000s, so a lot of it ages out together.

A big flat roof drains slower than it looks
In Airlake Industrial Park the deck is usually steel over bar joists, and the first thing we do is cut test squares to find out how wet the insulation under the old membrane is. Wet board has to come out. Leaving it in traps water against the deck, and the new TPO hides the problem for years. Long spans like these need tapered insulation built back toward the drains, because a roof that holds water after a spring rain will hold it all summer. We fasten heavier at the corners and along the perimeter, weld every seam hot and probe it, and flash the rooftop unit curbs and the roof level changes where drifted snow sits deepest. If the plant vents solvents or acids, we will say so and point you at PVC roofing, which stands up to that where TPO will not.
TPO Roofing in Lakeville
What TPO changes on a Lakeville flat roof
Slope rebuilt back toward the drains
Wide roofs like the ones in Airlake move water a long way to a few interior drains. We build tapered insulation back into the low spots so a spring rain leaves the roof by afternoon.
Wet insulation out, not covered up
Test cuts tell us how much of the old board is soaked. Anything wet comes off. New membrane over wet insulation looks finished on day one and rots the steel deck underneath for years.
White roof over an unconditioned plant
A lot of the buildings out here run little or no rooftop cooling, so the heat that comes through a dark roof lands on the floor below. Reflective TPO keeps a summer afternoon out of the work space.
Every seam welded hot and probed
TPO fails at the seams before it fails in the field. We weld with heat, not glue, and run a probe down every lap and every corner patch before the crew leaves the roof.
Drift zones flashed at roof steps
Snow slides off the taller sections of these buildings and piles against parapets and lower roofs. Those spots carry more load and stay wet longest, so the flashing there runs higher than the minimum.
A roof planned before the neighbors call
The Lakeville commercial corridor filled in over a short stretch of years, so its roofs come due together. Knowing where yours sits in that line lets you book the work instead of scrambling after a leak.
How we handle a Lakeville commercial roof
We open the roof before we quote
A number pulled off a satellite photo is a guess. We take core cuts, find the deck, count the layers, and price what is actually up there.
Straight talk on recover versus tear off
Sometimes a recover layer is honest work, and sometimes it just buries a wet roof. We tell you which one you have, and we will say when the smaller job is right.
We work around the dock schedule
Trucks do not stop for a reroof. We stage material, park equipment and run hot work where it will not block a dock door or a fire lane during your shift.
We stage a big roof properly
A hundred squares of insulation cannot sit in one pile on a bar joist deck. We load in over bearing points and keep your lot open for trucks while we do it.
Surprises get reported the same day
Nobody likes a change order at the end of the job. If the deck under a wet section turns out to be rusted through, you hear it that afternoon, with photos, before we cover it.

TPO questions from Lakeville building owners
What people in Lakeville ask us about this work. If yours is not covered, call and ask.
Can you install TPO over the existing roof on my Lakeville warehouse?
Sometimes. Code generally allows one recover over an existing roof, so if the building has only one layer, the insulation cores come back dry and the deck is sound, a recover saves a tear off. If the cores are wet or there are already two layers, it has to come off. We core the roof before we answer that.
Can TPO seams be welded in a Minnesota winter?
Yes, with care. Cold slows the weld and the membrane has to be clean and dry, which is the hard part when there is frost or blowing snow. We run test welds through the day as the temperature moves and adjust the machine. Emergency work happens in January. Full tear offs go better in a settled stretch of weather.
Water still sits on my flat roof two days after a rain. Is that normal?
No. Standing water that lingers is a sign the slope or the drains are not doing their job, and it is usually old compressed insulation, a clogged drain or a deck that has deflected between joists. Left alone it grows algae, freezes and works at the seams. Tapered insulation and drain work fix it during the reroof.
