Case Study: 27,000 SF Community Center Foam Roof Restoration — East Valley JCC, Chandler
A busy Chandler community center — with a preschool, gym, event spaces, and daily programming under the roof — needed a foam restoration done without disrupting a single class. We scraped, primed, patched, and locked 27,000 square feet of aging foam under two coats of ARMORCOAT AC100 white elastomeric while the JCC's daycare kids kept playing right below us.

The East Valley JCC at 908 N. Alma School Rd is one of the busiest community centers in the East Valley — a preschool with a full daycare, a fitness gym, event ballrooms, meeting rooms, and a Sunday-morning crowd all running under a single 27,000 sq ft flat foam roof. The building was originally foamed years ago, and the original topcoat had done its job: kept the foam dry and protected the substrate through more than a decade of Arizona sun. But by 2026 the topcoat had chalked out, the reflectivity was gone, small bubbles had appeared, and a handful of penetrations around HVAC curbs were starting to crack open.

The ProjectThe building, the client, and what we were solving for
The East Valley JCC at 908 N. Alma School Rd is one of the busiest community centers in the East Valley — a preschool with a full daycare, a fitness gym, event ballrooms, meeting rooms, and a Sunday-morning crowd all running under a single 27,000 sq ft flat foam roof. The building was originally foamed years ago, and the original topcoat had done its job: kept the foam dry and protected the substrate through more than a decade of Arizona sun. But by 2026 the topcoat had chalked out, the reflectivity was gone, small bubbles had appeared, and a handful of penetrations around HVAC curbs were starting to crack open.
The JCC's operations team didn't want a full replacement — the foam substrate was still solid. They wanted the smartest, longest-life restoration we could deliver: something that would keep the roof dry for another decade, cool the building down (reflectivity matters when you're running 40+ HVAC units and cooling a preschool full of kids), and — critically — happen without interrupting a single day of programming. Vanguard's answer was a full restoration: scrape, clean, ArmorPrime, ArmorPutty repair, and two coats of ARMORCOAT AC100.
The SystemThe system: ArmorPrime + ArmorPutty + 2 coats of ARMORCOAT AC100
Restoring a foam roof properly is not the same as just spraying more coating over the top. If you don't scrape the loose material, prime the substrate, and repair every crack and bubble first, the new coating fails at those same weak points within a couple of seasons. Vanguard's East Valley JCC restoration ran the complete ARMORCOAT restoration protocol.
- ArmorPrime foam roof primer — a single-component urethane primer designed specifically to lock ARMORCOAT AC100 to aged, weathered foam. Without a primer, elastomeric coatings peel off oxidized foam in under two years.
- ArmorPutty seam & penetration sealant — a high-solids urethane putty used to fill cracks, splits, bubbles cut open in the existing foam, and every roof penetration (vent stacks, HVAC curbs, drain edges).
- Reinforcing membrane — polyester reinforcement embedded in the ArmorPutty at wider cracks and stress points, so the repair moves with the foam instead of splitting again in the next thermal cycle.
- ARMORCOAT AC100 premium white elastomeric — 2 full coats applied at spec thickness. High-solids acrylic elastomeric with 85+ initial reflectivity and Title-24 / CRRC-listed cool-roof performance.
Our ApproachThe approach: a preschool doesn't stop for a roof project
The single biggest constraint on this job wasn't materials or square footage — it was the daycare. The JCC's preschool operates Monday through Friday, kids arrive by 7 AM, and the shaded play area sits directly under the west edge of the roof. Any dust, any drips, any equipment noise had to be managed around the schedule. Vanguard staged the entire project so the JCC's Executive Director could tell every parent, member, and staff member the same thing: nothing changes. The building stays open, the kids keep coming, the gym keeps its classes.
Vanguard's 8-step scope for East Valley JCC
- Scrape the roof — removed all loose, peeling, and chalking coating with hand and mechanical scrapers so the new system bonded to solid substrate, not failing material.
- Clean the roof — full sweep and rinse to strip dirt, dust, bird debris, and airborne pollution off the foam. A clean surface is non-negotiable for primer adhesion.
- Cut out and refill bubbles — every foam blister was cut open, the underlying moisture allowed to escape, and the void refilled with fresh polyurethane foam and sanded flush.
- Prime with ArmorPrime — full application of ArmorPrime foam roof primer across the entire 27,000 sq ft substrate, so the topcoat bonds mechanically and chemically instead of just sitting on top of aged foam.
- ArmorPutty crack & split repair — every crack, split, and hole in the existing foam was filled with ArmorPutty. Wider stress cracks were reinforced with embedded polyester membrane so the repair flexes with the roof.
- Seal every penetration — HVAC curbs, vent stacks, drain edges, conduit penetrations, and roof-mounted equipment all sealed with ArmorPutty before the topcoat was applied.
- Apply 2 coats of ARMORCOAT AC100 — two full passes of the premium white elastomeric applied at spec thickness in cross-hatched directions, so no pinhole or thin spot is left uncovered.
- Clean up and dispose — every day the crew broke down before daycare pickup. All job-related debris hauled off site, roof left broom-clean.
The JCC's operations team got a daily update — morning start time, when the west side would be worked, when the crew would break, when the drums would be moved. That kind of communication is why non-profit boards and community centers keep hiring us: they know they can promise their community that the building stays open, and we back that promise up.
The DetailThe detail: 40+ HVAC penetrations, a daycare edge, and a shared parapet with the neighbor
27,000 sq ft sounds like a lot of open roof, but the East Valley JCC is one of the most penetration-dense roofs in our portfolio. The overhead drone photos tell the story — 40+ HVAC units, dozens of vent stacks, exhaust hoods for the commercial kitchen, and a full run of gas piping across the eastern half. Every one of those penetrations is a potential leak point, and every one had to be scraped, primed, and sealed with ArmorPutty before the topcoat went on. This is the work that most restoration bids skip and that customers pay for two years later when a curb starts leaking.
The west side of the roof steps down to the daycare shade structures — the colorful shade sails you can see in the aerial photos. That edge got extra attention: no overspray, no dust plume, no dropped material. On the east side the JCC shares a parapet with the neighboring retail building, so the edge termination was cut clean and sealed neatly along the shared wall rather than lapped over. Small details, but they're what separates a 10-year restoration from a 3-year patch job.
The Warranty10-year no-leak warranty backed by an Arizona contractor with 68 years of local history
The East Valley JCC restoration is covered by Vanguard's standard 10-year no-leak material and labor warranty. If the roof leaks in the next decade for any reason covered by the warranty — coating failure, seam split, penetration seal failure, or workmanship defect — Vanguard returns to make it right at no cost to the JCC. That warranty is only as good as the company standing behind it: Vanguard Roofing AZ is a division of MSW Contracting LLC, a Chandler-based Arizona contractor that has been on East Valley roofs since 1957. AZ ROC CR-42 #289663 and R-62 #283025. GAF, Versico, and ARMORCOAT certified. A+ BBB. And headquartered a mile from the JCC.
The ResultsThe results — cooler building, brighter roof, and zero disruption to a busy community
The finished drone photos speak for themselves: 27,000 sq ft of pure white cool-roof elastomeric with every penetration flashed cleanly. The JCC's building runs cooler under the same HVAC load, the roof's warranty clock has been reset for another decade, and the preschool never missed a day. This is exactly the kind of foam restoration that keeps a non-profit's capital budget stretched — no full tear-off, no roof replacement, just the right restoration protocol executed by a certified crew.

FAQCommon questions
What was the scope of the East Valley JCC roof restoration in Chandler?
Vanguard restored 27,000 square feet of aging polyurethane spray foam roof at the East Valley Jewish Community Center on N. Alma School Rd in Chandler. The scope included scraping loose and peeling coating, cleaning the entire roof, cutting out and refilling foam bubbles, priming with ArmorPrime foam roof primer, repairing cracks and splits with ArmorPutty plus reinforcing membrane, sealing all roof penetrations with ArmorPutty, and applying two full coats of ARMORCOAT AC100 premium white elastomeric — all backed by a 10-year no-leak warranty.
Why does a foam roof need to be primed before recoating?
Aged polyurethane spray foam oxidizes and chalks over time as UV breaks down the surface. If you apply elastomeric coating directly to weathered foam, it bonds to that loose, chalky layer instead of the solid substrate — and the entire coating can peel off in one to two years. ArmorPrime is a single-component urethane primer engineered specifically to lock into oxidized foam and give the ARMORCOAT AC100 topcoat a chemical and mechanical bond that will last a decade or longer. Skipping the primer is one of the most common shortcuts on cheap restoration bids, and it's why so many foam recoats fail early.
How does ArmorPutty repair cracks and bubbles in an existing foam roof?
ArmorPutty is a high-solids urethane putty that flexes with the foam. For bubbles, we cut open each blister, let any trapped moisture escape, refill the void with fresh polyurethane foam, and then seal the patch with ArmorPutty. For cracks and splits, we clean the crack, apply ArmorPutty, embed a strip of polyester reinforcement membrane at wider cracks, and then feather the putty flush with the surrounding foam. Every roof penetration — HVAC curbs, vent stacks, drains — also gets sealed with ArmorPutty before the topcoat is applied. The result is a monolithic surface with no weak points for the topcoat to fail at.
Did the East Valley JCC have to close during the roof project?
No. The JCC's preschool, gym, event spaces, and daily programming all stayed fully operational throughout the restoration. Vanguard staged the work around the JCC's daily schedule — the crew broke down before daycare pickup, the west side of the roof (over the play area) was worked in a coordinated window with the daycare director, and all debris was hauled off site daily. This kind of coordination is standard on Vanguard's community center, HOA, school, and non-profit projects: the building stays open, the community keeps its programming, and the roof still gets done on time.
How long does an ARMORCOAT AC100 foam roof restoration last?
An ARMORCOAT AC100 restoration applied over a properly prepped and primed foam substrate typically extends the useful life of a commercial foam roof by 10 to 20 years. The AC100 topcoat itself carries a 10-year Vanguard no-leak material and labor warranty, and the restoration can be recoated again in the future at a fraction of the cost of a full replacement — that's the key advantage of foam plus elastomeric as a system. Instead of tearing off and rebuilding every 15 years, you're recoating every decade for pennies on the replacement-cost dollar.
