Government TPO Roofing
TPO membrane on government flat roofs.
What government TPO roofing involves
Heat-welded TPO with every seam probed, and the drains, curbs and parapets detailed properly.
TPO fails at seams and terminations, not in the open field. That is where the work goes.
What matters on government TPO roofing
Drainage before material
The first question on any low-slope roof is where the water goes. Ponding is what kills membranes, and a roof that holds water for days after a storm will fail early regardless of which sheet is on it. We look at the slope, the drains and the terminations before we talk about material.
Seams and terminations
Field failures on commercial roofs are rare. Failures at seams, curbs, drains and the parapet edge are common. A hot-air welded seam that has been probed is a continuous sheet. Anything taped or glued and unverified is a scheduled leak.
TPO on government buildings
TPO is a white, heat-welded membrane that reflects a lot of summer heat, which matters on a big building with the air conditioning running all day.
The welds are what make it one sheet. Every seam gets checked with a probe before we leave, and the details around units and drains get the most time.
We work Salt Lake City & surrounding counties, 9 counties in all, with 27 years in the trade and the last 8 as Hancock Signature.
How the system goes together
Ridge vent against box vents
A continuous ridge slot pulls air along the entire peak, which is why it outperforms a row of box vents on most houses. Box vents still win in specific situations: a hip roof with almost no ridge to cut, a roof broken into separate attic spaces that do not share air, or a low ridge where a slot would sit under drifted snow all winter.
Never mix the two on one attic
Put both on the same space and the ridge pulls its air from the nearest box vent instead of from the soffit. The attic barely moves and the roof looks correctly vented from the driveway.
Fasteners rust from the inside out
Screws and nails on a roof within reach of the lake air corrode faster than the same hardware would inland. A plain steel nail head disappears under a shingle and takes years off the roof’s hold without a single visible symptom. Hot-dipped galvanized or stainless where the metal is exposed is a small line item that decides whether the roof reaches its rated life.
Mixed metals make it worse
Aluminum flashing pinned with the wrong screw sets up a reaction that eats the softer metal at every contact point.
We look at the old nails
What came out of the last roof tells you what to put in the new one.
What we check
- Field condition and granule loss
- Valleys, ridges and every transition
- Penetrations and their flashing
- Gutter and fascia condition
How we approach it
Look first
We get on the roof and read what is actually happening before quoting anything.
Say what we find
Photographs and a plain explanation, including when the answer is that you do not need us yet.
Built in sequence
Crews we hire and run, working the right detail in the right order.
Leave it clean
Magnet over the yard, container gone, walked with you.
Wind, water and dust, in that order
Ask what actually kills roofs in this part of the state and the answer runs wind first, then water that could not get away, then the grit that the wind delivered. Each one makes the next worse. A wind-broken seal lets water in. Water carries grit into a lap. Grit holds moisture against the mat. None of it is dramatic and all of it compounds.
Why we start at the edges
Perimeters and penetrations are where all three arrive together, so that is where an honest look begins.
Snow sliding off steep pitch
Steep roofs shed, which is good for the roof and hard on everything below it. A loaded slope lets go at once and takes gutters, vent caps and the occasional shrub with it. On metal it happens faster because there is nothing to hold it. Homes with steep pitch over a walkway or a doorway get looked at differently than the same roof over an open yard.
Snow retention when it matters
Where a slide is a hazard, cleats or a retention rail spread the load and let it melt off instead of releasing in one sheet.
Where roofs go wrong
The shortcut we see most
A membrane laid over wet insulation because tearing off would have cost a day. The roof looks finished, the moisture stays underneath, and the sheet fails early from below.
What good looks like instead
Moisture surveyed, wet sections cut out and replaced, drainage corrected, then the membrane installed and its seams probed.
Signs worth a look
- Ponding water still standing two days after rain
- Seams that have lifted or opened at an edge
- Blisters or ridging across the field
- Interior staining near drains, curbs or the parapet
What to expect
Scheduling around your operation
Most commercial work can be staged so the disruptive part happens when the building is quiet. Tear-off noise, crane or hoist time and material deliveries all get planned against your hours rather than ours.
What the roof survey covers
Before specifying anything we survey the existing assembly: slope and drainage, moisture in the insulation, the condition of seams and terminations, and how the roof is being used. A roof somebody walks on weekly needs a different answer from one nobody touches.
Documentation
Commercial and public work runs on records. We photograph the existing condition, the work in progress and the finished assembly, so there is a file rather than a recollection.

Questions we get asked
Not the question you had? Call the shop and ask a person. We would rather talk it through than have you guess from a website.
(801) 382-8898Which membrane is right for my building?
It depends on the traffic, the exposure and what comes out of the exhaust. TPO and PVC are welded and light, EPDM is proven and has fewer seams in wide sheets, mod-bit and built-up are heavier assemblies. We specify for the building rather than for what is on the truck.
Can you work around our business hours?
Usually. Most commercial work can be staged so the noisy part happens when the building is quiet, and we talk about that before the schedule is set.
How long does a commercial membrane last?
It depends far more on drainage and detailing than on the sheet itself. A membrane with standing water on it and a membrane that drains properly will not last the same length of time.
What makes a Utah roof different?
Snow load, ice at the eaves, canyon wind and high-altitude sun, all on the same roof. A crew that learned roofing somewhere mild has to learn it again up here.
Will you tell me if I do not need a new roof?
Yes. Plenty of what we look at turns out to be a repair, and we say so. A roof with years left in it gets left alone, and you get the photographs either way.
Do you handle the insurance side?
On hail-damaged roofs, we work with your insurance to get the roof covered. We document the damage thoroughly with photographs, so the claim reflects what is actually on the roof.
