Rio Rico commercial roof coating for wide distribution and light industrial roofs, starting with where water stands after a storm and why.
Rio Rico sits just north of Nogales along I-19, and much of its commercial space sits under broad low-slope roofs.
A roof hundreds of feet across needs only a slight sag between drains to hold water. After summer storms, that water can sit for a day or more, and the dust it leaves behind marks the ring.
Ponding rings are where coatings wear through first, so we start every Rio Rico roof by finding them, checking the insulation under them, and planning the coating around them.
Low-slope roofs collect water in the same few places. The numbers on the plan match the list below.
Long spans sag a little between structural supports, and that is where water lingers. The dried dust ring shows the edge of each pond and where extra coating thickness belongs.
A drain set slightly above the surrounding roof leaves a shallow pond around it. Strainers clogged with dust and debris do the same after every storm.
Water that sits long enough finds small openings, and the insulation under a pond is the first to get wet. Core cuts confirm it stays dry before coating.
Lap seams that run through a ponding area are underwater for hours at a time. Those seams get fabric reinforcement before anything else is coated. Seams on higher ground get the same treatment later.
Rooftop units spread across a big roof each add a curb and a service path. Curb flashing and the paths to it are checked for tears and wear.
On a Rio Rico roof that is dry underneath, coating can bring these results.
Silicone and thicker passes hold up in the rings where water sits after storms, the same spots where a worn roof surface fails first.
Coating happens on the roof surface in sections, so trucks, forklifts, and staff below keep working through the job.
A broad roof membrane that is still attached and dry stays in place, which avoids hauling away tons of old material.
A white surface across a large roof turns back much of the summer sun that would heat the building below.
Three systems cover most wide low-slope roofs in Rio Rico.
Bright White SiliconeSilicone is the first choice when water stands in rings between drains, since it keeps working under standing water.
Matte White AcrylicAcrylic suits the parts of a Rio Rico roof that drain within hours and sit beside dusty yards and gravel lots.
Red-Brown Primer, White TopcoatMetal warehouse roofs here get fastener and lap work, rust primer, and a topcoat matched to how they drain.
Water still standing on the roof a day after rain is the first thing we look at. Call and tell us where it sits and how long it stays.
Big roofs are coated in sections, and the low spots set the plan.
We walk the full roof, mark every ponding ring and drain, and take moisture readings under each one. Photos of the roof after a storm help if you have them.
Clogged strainers are cleared and loose clamping rings tightened. Drains sitting too high, or ponds too deep for coating alone, get corrected before any coating is planned.
Insulation that reads wet under a pond is cut out and replaced. Coating a wet area would trap the water in the roof for years.
Seams that cross ponding areas and the membrane around each drain bowl get fabric set in coating, adding thickness where the water sits. Drain flashing is checked again after it is wrapped.
The roof is coated in planned sections so operations below keep running. Low spots get extra passes, and thickness readings are logged as each section is finished.
Rio Rico sits between Nogales and the towns farther up I-19.
Cold storage and produce warehouse roofs along the border, a few miles south on I-19.
Farm and small metal roofs farther north along the Santa Cruz River.
Gallery and shop roofs coated while the doors stay open.
Main-street storefront roofs northeast on SR 82.
Thick enough to meet the coating maker's dry-mil spec for that product and surface, measured in thousandths of an inch. Crews check wet film thickness with a gauge as they go.
Thin spots wear through first at seams and ponding rings, so extra passes go over those areas, and the readings are recorded across the whole roof.
Rio Rico is unincorporated, so roof work falls under the Santa Cruz County Building Department. A straight recoat is treated differently from work that replaces wet insulation or adds curbs, so check with the county before work starts.
A coating lets the roof survive ponding; it does not move the water. Shallow ponds that dry within a day or two are handled with silicone and extra thickness. Deeper ponds call for drain work, tapered insulation, or foam first.
Yes. Large roofs are often coated in phases, starting with the sections over the most sensitive spaces or the worst ponding. Each phase is finished to full thickness before the next begins.
The surface has to be fully dry, including under any dirt left behind by the pond. After monsoon storms that can take a few days of sun, and moisture readings confirm it before coating.
No. The work is on the roof surface. Material is staged at a spot away from active docks, and the crew plans the lift or ladder access around truck traffic.
Standing water speeds up surface wear, loosens seams it covers, and collects dust that holds moisture against the roof. Over many seasons, water finds a way into the insulation below.
It is the usual choice where water stands. Parts of the same roof that drain well can take acrylic, and very deep ponds are better fixed with slope before any coating.
