Built-up roofing is old technology, and that is exactly why it still shows up on a lot of the industrial buildings inside Business Depot Ogden and the older manufacturing plants along the I-15 corridor: it is a known quantity with decades of performance data behind it. The problem in this market is not the system itself. It is bids that quote "built-up roofing" without specifying the felt weight, ply count, or flood coat thickness that actually determines how long the roof lasts.
On heavy industrial buildings with significant rooftop equipment, foot traffic, and structural capacity to spare, a multi-ply built-up roof with gravel surfacing holds up to abuse that a single-ply membrane would not tolerate as well. We still install and repair BUR on older manufacturing buildings and warehouse structures around Business Depot Ogden where the existing roof is already built-up and in reasonable condition, and replacing it in kind, rather than switching systems, is often the more cost-effective and lower-risk choice.
We also see BUR specified on buildings with rooftop crane rails, catwalks, or other permanently mounted structural elements, where a multi-ply asphalt system tolerates the repeated foot traffic and point loading around those fixtures better than a thinner single-ply membrane would over time.
A standard BUR assembly specifies felt weight in pounds per square and a ply count, typically three or four plies depending on the manufacturer system and warranty term. We have seen bids that quote a four-ply system and deliver three, or quote a heavier felt weight and install a lighter one, both of which save material cost on a large roof while shortening its service life. On a roof the size of a typical Business Depot Ogden building, that difference in felt weight adds up to a meaningful cost saving for the contractor and a meaningful loss of service life for the owner.
We name the exact felt weight and ply count in every BUR bid, along with the flood coat thickness, so there is nothing ambiguous about what is actually being installed.
We also document ply orientation and lap width during installation, since felt laps installed too narrow or run in the wrong direction relative to roof slope create channels where water can travel sideways under the membrane before it finds a way through, a defect that is nearly impossible to diagnose after the fact without cutting into the roof.
Gravel-surfaced BUR roofs add real weight to a structure, and that weight concentrates unevenly, more at parapets and roof edges where wind and drift push both snow and loose gravel. On a building already carrying a heavy Weber County snow load, we check how that combined weight distributes across the structure before recommending gravel surfacing over a smoother cap sheet finish, particularly on older buildings where the original structural design may not have anticipated decades of accumulated ballast redistribution.
Traditional BUR installation uses a hot asphalt kettle, and running one on an active manufacturing or warehouse site around Hill AFB's supplier network or Business Depot Ogden means coordinating around other operations, equipment, and personnel that a lower bid may not account for in scheduling. We plan kettle placement, fire watch, and material staging around a facility's actual operating hours rather than assuming an empty site.
We schedule kettle work for early morning hours where possible, both to avoid peak wind conditions that develop later in the day near the canyon and to reduce the amount of time an open flame or hot material sits near an occupied building during business hours.
It is older technology, but it remains a sound, durable choice for the right building, particularly heavy industrial roofs with significant foot traffic. The right system depends on the building, not the age of the technology.
Ask for the specific manufacturer assembly name and felt weight in pounds per square. We include that detail in every BUR bid so it can be checked directly.
It can, particularly on older buildings not originally designed for decades of ballast redistribution combined with heavy snow load. We review structural capacity before recommending gravel surfacing.
Yes, where the manufacturer system calls for it, with a documented fire-watch and safety plan coordinated around the facility's active operations.
A correctly specified four-ply system with proper flood coat commonly reaches 20 to 25 years, with maintenance extending that range further.
