Commercial Roofers in Lehi, UT

Commercial roofers serving Lehi, UT should document leak sources, wet insulation, drainage, edge details, penetrations, and repair history before recommending a scope. Lehi has added more office square footage in the last decade than most of the rest of Utah County combined, and almost all of it is low-slope, single-ply, and glass-heavy. That combination puts a lot of pressure on the roof to carry insulation performance the curtain wall can't, which is a different design problem than the older retail and industrial buildings we work on elsewhere in the valley.

Why Silicon Slopes Campuses Roof Differently Than Older Office Stock

The tech campuses along the I-15 frontage and around Thanksgiving Point are newer construction, mostly single-story or low-rise, with big open floor plates and heavy glazing on the exterior walls. Glass loses and gains heat far faster than insulated wall assembly, which means the roof has to make up more of the building's total thermal performance than it would on a conventional office box.

We see this show up in how these buildings are cooled: rooftop units and packaged VAV systems working against solar gain coming through glass on one side and radiant heat coming down through the roof deck on the other. A roof assembly that's only meeting code-minimum continuous insulation isn't pulling its weight on a building like that.

Continuous Insulation and Where Thermal Bridging Actually Happens

Current energy code pushes continuous insulation above the deck specifically to cut thermal bridging at fasteners, purlins, and parapet transitions, and on Lehi's newer construction we're usually verifying that the as-built assembly matches what was specced rather than starting from scratch. Value engineering during construction is where continuous insulation R-value most often gets quietly trimmed.

Parapet-to-roof transitions are the detail we check first on any campus building, because that's where a thinner-than-specified insulation run creates a cold bridge that shows up later as condensation staining on the interior ceiling below, usually along the perimeter offices that got the corner glass everyone wanted.

Cooling Load on Large Single-Story Footprints

A 150,000-square-foot single-story campus building has a roof-to-floor-area ratio that a downtown high-rise never sees , the entire roof is doing thermal work for one floor of occupants. That makes the membrane's solar reflectance index a real line item in the building's cooling bill, not a marketing footnote.

• Membrane SRI rating relative to the building's actual roof area and orientation
• Insulation thickness and R-value at the deck versus at tapered crickets and drains
• Rooftop unit curb count and spacing, since campus buildings often run dozens of units
• Vapor retarder placement given Lehi's freeze-thaw winters and dry summers
• Warranty terms that match the building owner's hold period, not simply the cheapest option

Thanksgiving Point's Mixed Commercial Roof Stock

Thanksgiving Point itself is a different animal from the office campuses around it , event venues, retail buildings, and gardens facilities with more varied roof geometry and occupancy patterns than a flat corporate box. Buildings that host events need HVAC systems that can swing quickly between empty and full occupancy, and the roof assembly has to support that swing without lagging behind it.

We treat those buildings' insulation and reflectivity specs around occupancy variability rather than a flat year-round assumption, because a roof sized for steady partial occupancy behaves differently under a packed weekend event than an office roof does on an average Tuesday.

Snow Load and Wasatch Front Winters on Flat Corporate Roofs

Lehi sits close enough to the Wasatch that winter snow load and freeze-thaw both matter on these large flat roofs, and drainage design gets more scrutiny here than on a smaller retail building. Large flat roof areas with insufficient drain count or improperly tapered insulation pond snowmelt at the parapet edges, which is exactly where thermal bridging already concentrates condensation risk.

We coordinate roof drainage capacity with the insulation and membrane spec together, since a beautifully insulated roof that can't shed meltwater fast enough just moves the problem from an energy bill to a leak.

What Lehi Building Owners Ask Us

Does a reflective membrane actually help on a building with this much glass?

Yes, though it's addressing a different load than the glass does. The glazing drives heat gain through the walls; the roof membrane and insulation determine how much additional heat the roof deck contributes on top of that. Both need attention, and neither substitutes for the other.

How do you verify continuous insulation on a building we didn't build?

We core sample at several points across the roof to measure actual installed thickness and compare it against the stamped drawings if they're available, or against current code minimums if they aren't.

Is a campus building's roof warranty different from a standard office roof?

The warranty terms depend on the membrane and system manufacturer, but campus-scale roofs often justify a longer-term system warranty given the roof area involved and the cost of remobilizing a crew for repeat repairs.

What happens if we add rooftop units later for a tenant buildout?

New curbs and penetrations need to be flashed and insulated to match the surrounding assembly, or they become the weak point in an otherwise well-performing roof. We coordinate that work directly with the mechanical contractor doing the buildout.
