RTU screening flagged before turnover? That is the job we fix.

CME delivers RTU screening as a submittal-ready package: shop drawings and mechanical roof screen details your AHJ (authority having jurisdiction, the office that signs off plan review) can read, steel sized to your roof, and field work that does not turn into a trim kit and a grinder. Thirty-five years on nothing but commercial screening.

RTU screening scope that survives plan review and closeout

You are looking at a roof plan, a plan-review comment, or a zoning line that says equipment has to disappear from view. The calendar does not care. That is where catalog panels and generic fences blow up.

Cold-climate roofs

Cold-climate roofs need intakes that still breathe when snow and ice hit. See RTU snow screens for louvered, load-rated work with your structural engineer.

Full visual block-out (solid)

Zoning or design says the RTU cannot read from the sidewalk. Solid panels hide packaged units, exhaust fans, and cooling towers without turning the roof into a billboard of raw steel.

Airflow without a coil choke (perforated and louvered)

Mechanical gives you a free-area number; you need a pattern that hits it. Perforated faces soften the view. When the engineer wants a defined open area, louvered layouts do the math in the shop, not with a field-drilled guess.

Re-roofs that cannot take new penetrations

Membrane warranty and existing insulation often mean fewer holes. Non-penetrating rooftop HVAC screen systems bolt to your engineer's attachment story, not a kit that usually works. Cold jobs add snow load and drift; we coordinate with the engineer of record so the wall survives winter, not just permit issuance.

We work where your permit is issued

Your superintendent is holding a date. Your reviewer is holding redlines. We get it. Fabrication ships from our shop, crews meet your team on the roof, and one PM line owns the thread so you are not babysitting a blind drop-ship.

RTU screening reads like zoning in one city and IBC Chapter 15 language in the next. For a straight read on major metros and the Section 1511.6 baseline, use our RTU screening requirements by city guide.

Cities where we keep showing up for your team

Dallas

Your PM is not the first person to get a screening curveball in DFW. Examiners here see our drawing set format weekly, so height and attachment stop turning into a long email chain.

Los Angeles

Visibility rules and LABC Chapter 15 land on one submittal sheet, so your architect is not guessing what the reviewer wants to circle.

New York City

All-sides screening language and DOB-facing elevations read like people who have been through plan review before, because we have.

Phoenix

Heat, wind, and hide it from the street belong in the same RTU screening package, not three separate arguments after permit.

San Diego

Coastal exposure finishes and public-view corridors get spelled out up front, so closeout is not a scramble for touch-up and stories.

Seattle

Mechanical permit comments get answers your reviewer can follow on paper, not photos of a mock-up pasted into a thread.

Problems we kill before they hit your punch list

Last-minute code flag

Turnover is on the calendar. Plan review drops a rooftop screening note nobody priced. The GC eats the delay, unless someone can turn a drawing set and a fab schedule fast. CME builds screening-only submittals so you are not explaining a fence catalog to a structural reviewer.

We stay on the thread until the comment clears or the CO path is real.

Field cuts that show

Kit walls show up long. The curb is wrong. Suddenly every vertical joint is a jobsite edit and the architect is taking photos from the parking lot. Custom fab matches the roof you built, not the roof the catalog guessed.

Panels leave the shop to your approved shop drawings, trim pieces included.

Hardware that walks

Doors sag. Posts flex. Finish chalks off in the first winter. Cheap screening turns into a maintenance ticket and a bad owner handoff.

26-gauge steel, engineered attachment, powder coat that matches your spec, built for service trucks, not just the grand opening.

No drawings for plan review

The equipment is on the roof schedule, but the screen only exists as a note: by others. The AHJ wants sections, heights relative to parapet, and attachment loads. Air does not move until someone draws it.

We issue mechanical roof screen details and elevations sized for your reviewer, not a sketch on a napkin.

Why crews stop fighting us at closeout

35 years on screening only

Not general metal fab that also does roofs. Screening is the scope: RTUs, exhaust, towers, louvers, snow loads, plan review comments. That focus is why repeat GCs call before they price the alternates.

General shops treat the screen like trim. We treat it like a building component.

Zero field-cut kits

Every run is drawn to your equipment map and roof edges. Brackets, splices, and door locations are decided before the boom truck shows up.

Catalog systems look cheap until you add the labor to make them fit.

AHJ-ready drawing packages

Plan review gets plans, sections, and details that name attachment, height, and finish, the stuff examiners actually circle.

Most vendors stop at a sales drawing. We stay through the redlines.

Freight and install on one call

We coordinate crating, delivery windows, and field crews so your superintendent is not babysitting a blind shipment.

Drop-ship metal is not a screened roof.

Frequently Asked Questions

Straight talk on RTU screening, roof equipment screens, mechanical roof screen details, and how we work with your plans and AHJ.

A roof screen or rooftop equipment screen is a built screen wall or enclosure around rooftop mechanical equipment so it is concealed from public view. It is usually steel, sized to your plan, and documented for plan review with wind and attachment appropriate to the job.

HVAC screening is the code- and design-driven side of that work: concealing rooftop HVAC and related equipment while keeping service access, tied to zoning, design guidelines, or visibility rules, not a decorative residential fence.

The large unit you see on many commercial roofs is often a packaged rooftop unit (RTU) or similar centralized HVAC. We also screen exhaust fans, cooling towers, and other rooftop mechanical. Our scope is the screen system around that equipment.

On commercial projects you typically do not hide equipment with ad-hoc wraps. You specify a code-compliant screen: height, materials, attachment, wind and seismic coordination, and service doors. We fabricate custom steel screen walls and coordinate shop drawings with your architect, engineer, and AHJ so screening passes review and still supports maintenance.

We build solid (non-perforated) and perforated steel panels, louvered mechanical equipment screens when the engineer needs a set open area for airflow (lead time can be slightly longer than solid runs), and non-penetrating rooftop HVAC screen systems when the roof assembly or warranty should limit new penetrations.

For non-penetrating work, expect engineered attachment to the roof, shop drawings, wind documentation when required, exposure-rated hardware and finishes, and service doors aligned to maintenance paths, coordinated with your structural engineer of record, not a generic kit.

We fabricate from 26-gauge steel with in-house blasting and powder coating so the screen matches your finish schedule and holds up in weather. Wind, attachment, and door hardware are part of the engineered system, not just the panel skin.

Every screen is custom fabricated, so there is no one-size price list. Quotes depend on lineal footage, height, panel type (solid, perforated, louvered), finish, freight, and whether we are supplying install. Share your roof plan and schedule, we will price from real scope rather than guesswork.

We produce shop drawings and mechanical roof screen details for AHJ review: rooftop plans with screen location and height relative to equipment, elevations from primary views, attachment and base details, finish callouts, and notes for wind and service access. The package follows what your city or reviewer requests.

Yes. Teams in cold climates sometimes look for RTU snow screens or winter-rated RTU screening. We treat that as standard commercial work with structural coordination: snow load, drift, ice, and wind on parapets drive attachment, gauge, bracing, and door locations. We align shop drawings and mechanical roof screen details with your engineer of record and local criteria so the roof equipment screen performs year-round, not just at permit issuance.

Yes. We coordinate fabrication, freight, and field install across the USA. If you are searching for non-penetrating rooftop HVAC screens near me or a strictly local crew, still call, we align freight and field availability with your site.

We often help on late-stage projects once rooftop layout is firm. We do not install residential privacy screens around home AC units, our work is commercial rooftop mechanical screening only.
