Commercial Roofing in Founders District, Las Vegas, NV

Existing roof: what it can accept

The first filter is the roof already in place. A recover needs a dry, firm substrate with enough bond and a deck that can carry the added weight. A tear-off is called for when insulation is wet, the deck is damaged or earlier recovers have already stacked layers on the roof. A test cut in each roof zone answers these questions, and a moisture survey widens the answer across the whole surface.

We also look at how the old roof was attached, because a ballasted, adhered or mechanically fastened assembly each demands different handling. Gravel or ballast must be removed and stored, adhered systems need a compatible surface, and fastened sheets need pull tests. The cost of a recover versus a tear-off follows from those findings, and it is a number the owner can read in the proposal.

Drainage is part of the same review. A roof that has settled over the years may hold water in new places, and a new membrane laid over the same low spots inherits the same problem. If the slope to the drains is poor, tapered insulation can be added to the scope. Edge conditions get equal attention: the parapet height, the wall flashing and the coping decide how the new membrane terminates, and a recover that cannot meet the wall flashing height is a reason to tear off.

Commercial Roofing Questions

Which test findings decide between a recover and a tear-off?

Dry, firm insulation with a bonded membrane and a sound deck allows a recover. Wet or crumbled insulation, a damaged deck or layers already stacked on the roof send the job to a tear-off. We take a test cut in each roof zone and add a moisture survey, so the decision rests on readings across the whole surface instead of one sample.

How does PVC differ from TPO for a sun-exposed roof?

Both are heat-welded, reflective single-ply membranes. PVC tends to resist grease and many chemicals better, which matters near kitchen exhaust or process vents. TPO is widely used where a light, reflective surface and cost are the priorities. The right one depends on what is on the roof and what the owner expects from its service life.

What does a metal roof retrofit avoid?

It avoids full tear-off of a sloped steel roof whose fasteners or panel laps are leaking. New framing or purlins carry new panels over the old, and the building keeps operating. It adds weight and changes the edge details, so the structure and drainage are checked first, and the existing panels must be sound enough to support the new layer.

Why does the Nevada energy code come up when a roof is replaced?

A replacement can trigger insulation requirements, under the energy code Nevada adopted for 2024. The city's permit office states the exact requirement, which is why we look up the address early. We list insulation thickness and cover board on the proposal as separate lines, so the reviewer sees what the roof will contain and what each item adds.

How should an owner phase work across two or more roofs?

Rank by active leaks first, then exposed details, then remaining membrane life. Survey the properties in one trip so conditions compare directly. Place the first order for the roof with the worst water path, and schedule the second for a steadier weather window. A capital plan then spreads the remaining work over budget cycles.

Heat and UV: what the surface faces every day

Roof membranes in the valley's desert setting absorb ultraviolet light and heat for most of the year, and plasticizers, binders and sealants slowly degrade. A dark roof surface can run far above the air temperature on a summer afternoon.

A reflective surface lowers that load, and The statewide energy code raises the insulation question on any replacement. We put insulation thickness, the cover board and the reflectivity of the finished surface on the proposal as separate lines, so a reviewer can check them quickly.

Owners sometimes ask whether a coating can stand in for a new roof. A coating can restore a sound, dry membrane, and a Cashman District owner and a Founders District owner would both be told the same thing: coating does not replace insulation that has gone wet. The moisture survey comes first, and the coating decision follows its result.

Lead time and sequencing: what sets the calendar

The calendar for a replacement is set by four things: the permit path, material lead time, the availability of tenants and the summer storm season. Permits depend on the jurisdiction, so the address is confirmed first. Material lead time varies by system and by order size, so we place orders as soon as the scope is approved. Tenant constraints set the working hours, and the summer storms tend to break up large open sections.

We schedule the largest tear-off areas for steadier weeks and use small sections during storm months. Owners with several properties, such as one in Founders District and one in the Market District, can ask us to line up the surveys in one trip and phase the work by priority. A roof capital plan turns those findings into a multi-year budget.
