Gibraltar Closes $1.335B OmniMax Deal — Accessory & Rainware Scale Just Jumped

Gibraltar Industries (Nasdaq: ROCK) closed its all-cash acquisition of OmniMax International on Feb. 2, 2026 — $1.335 billion, subject to customary adjustments — after clearing regulatory approvals. The deal was announced Nov. 17, 2025. For roofing distributors and contractors, this is not a generic building-products mash-up: OmniMax is a major U.S./Canada player in residential roofing accessories and rainware, with brands that already sit on many branch shelves and job trucks.

Gibraltar’s IR release frames the close as leaping its building-products growth strategy ahead by years, with Residential expected to represent over 80% of total revenue and adjusted EBITDA post-combination. Channel math just got thicker on gutters, accessories, and rain dispersion.

What’s on the record

• Close date: Feb. 2, 2026 (Gibraltar IR / Business Wire; SEC 8-K).
• Price: $1.335B cash from Strategic Value Partners funds, subject to customary adjustments.
• OmniMax lane: Residential roofing accessories and rainwater management; manufacturing footprint across the U.S. and Canada.
• Brand portfolio (company-stated): Amerimax, Berger, Flamco, Verde, Millennium Metals, Nu-Ray Metals, Hancock Enterprises.
• Pre-deal scale (announce metrics): Expected 2025 adjusted net sales ~$565M and adjusted EBITDA ~$110M; run-rate cost synergies originally cited at $35M with ~$100M cash tax benefits.
• Post-close synergy update: Gibraltar now cites a path to $27M cost synergies plus working-capital savings near-term, and $35M by end of year three; delever target 2.0–2.5x within 24 months.
• Financing: New senior secured term loans totaling $1.3B plus an upsized $500M revolver used with cash on hand.

“We now anticipate the Residential segment will represent over 80% of our total revenue and adjusted EBITDA, positioning Gibraltar as a scaled, high-performing platform in residential building products,” Bill Bosway, Gibraltar Chairman and CEO, said in the Feb. 2 close release.

Why distributors and contractors should care

Accessory and rainware SKUs are the quiet margin and service layer on steep-slope work — drip edge, vents, flashings, gutters, downspouts, and related metals. When one public platform absorbs a national accessory/rainware manufacturer with deep big-box and distributor relationships, expect:

• SKU and brand rationalization risk: Amerimax / Berger / Flamco / Verde / Millennium / Nu-Ray / Hancock lines may see packaging, lead-time, or program changes as Gibraltar integrates. Ask your branch which brands stay primary and which become secondary.
• Allocation and program leverage: A larger residential platform can renegotiate distributor and retailer programs. Independents should lock in written pricing and rebate terms for peak season, not handshake history.
• Gutter and rainware as a growth wedge: Shops that already sell/install gutters and accessories may see more manufacturer push into those jobs. Shops that ignore rainware leave that ticket to someone else on the same roof.
• Spec and warranty continuity: Confirm whether existing warranties, color matches, and compatible accessory lists change after rebrand or plant consolidation. Document what you installed last year before a catalog rewrite blindsides a callback.

Channel checklist for the next 90 days

• Call your primary yard: which OmniMax brands remain stocked locally, and are any SKUs moving to special-order?
• Update estimating templates for drip edge, starter, ridge vent, and gutter add-ons — don’t leave accessory dollars on the roof edge.
• Watch Gibraltar quarterly commentary for Residential mix and synergy delivery; integration noise often shows up as short-term fill-rate hiccups before it shows up as better availability.
• If you private-label or heavily prefer one OmniMax brand, ask for a written continuity letter. Hope is not a purchase order.

The Ridge Report take: this closes a major accessory-and-rainware scale-up under a public residential platform. Treat it as a channel event, not a press-release curiosity. Your counter conversation this spring should include who owns the gutter/accessory aisle — and whether your truck is still specified into it.
