New Castle Building Products

What New Castle Building Products does

New Castle Building Products is a family-owned exterior building materials distributor serving professional contractors and commercial and residential property owners across six Northeastern U.S. states (New York, New Jersey, Connecticut, Massachusetts, Pennsylvania, Maryland). Founded in 2002 by Kris Steele through the acquisition of Castle Building Products, the company has grown from 12 employees and 4 delivery trucks to 425+ employees operating 24 branch and warehouse-distribution locations, organized around three brand lines: the flagship NCBP exterior building materials business, the New Castle Metal division (launched 2016, 6 warehouse-distribution locations), and New Castle Waterproofing & Restoration (launched 2024).

The product portfolio spans residential and commercial roofing, metal roofing and flat stock, siding, decking and trim, waterproofing membranes and sealants, windows, skylights, roof hatches and doors, tools and fasteners, and NCBP-branded private label consumables (repair tape, adhesives, cements, coatings, primers, underlayments). Sourcing is anchored by 400+ vendor partnerships with manufacturers including GAF, Elevate, James Hardie, Atlas, VELUX, and Henry Carlisle. In 2026 the firm implemented Descartes Systems Group's route planning and execution platform to centralize dispatch and dynamically optimize fleet routing, reducing annual fleet mileage by approximately 25,000 miles.

Commercial mechanics are quote-based across a 24-location counter sales and fleet delivery footprint, targeting professional contractors (primary), commercial property owners, and residential property owners. Distribution is exclusively physical; the firm offers a dedicated commercial sales department, credit services and online bill payment, a tapered-insulation custom department, and job-site delivery via company-owned fleet. The company has operated continuously as a private, family-owned business with no external equity or holding-company structure reported.

Product overview

New Castle Building Products is a building materials distributor offering a comprehensive portfolio of exterior building products organized across multiple categories and private label offerings.

Private label offerings include repair tapes, adhesives, cements, coatings, primers, and underlayments under the NCBP brand.

Scale indicators5 records

Recent moves11 records

Expansion highlights5 records

Broad incumbents

• Allied Building Products (now part of HD Supply): Legacy national roofing and exterior building products distributor, acquired by HD Supply in 2018. Relevant as the same distributor category where NCBP's founder began his career and as a larger incumbent in the channel.
• Home Depot (Pro / Interline Brands): Big-box home improvement retailer with a rapidly expanded Pro contractor program offering roofing, siding, and exterior materials. Competes for the same contractor customer base within NCBP's six-state footprint.
• Lowe's (Pro Business): Second-largest U.S. home improvement retailer with a dedicated Pro contractor offering that competes for residential and small-commercial contractors on roofing, siding, and exterior products within the Northeast.
• Ferguson Enterprises: Large publicly-traded distributor of plumbing, HVAC, and specialty building products. Comparable as a multi-branch building-products distributor serving professional contractors, though with a different primary vertical.

Direct peers

• ABC Supply Co. Largest wholesale distributor of roofing, siding, windows, and exterior building products in North America, operating hundreds of branches across the U.S. Directly comparable as a B2B roofing-materials distributor serving professional contractors with a multi-state branch-based model.
• Waudena Group: Family-owned roofing and building materials distributor serving the Midwest and South. Comparable as a multi-generation family-owned, multi-branch roofing distributor with similar contractor-led GTM motion.
• Lansing Building Products: Specialty building products distributor focused on exterior building products including siding, soffit, and trim across multiple U.S. regions. Overlaps with NCBP in exterior-building-product distribution to contractors.
• SRS Distribution: National roofing and building products distributor with hundreds of branches across the U.S., serving professional contractors. Directly comparable given overlapping product categories (roofing, siding, waterproofing), contractor customer base, and branch-led distribution model.
• Beacon Building Products (now QXO): Major publicly-traded distributor of roofing and building products (acquired by QXO in 2024-2025). Closely comparable product mix and contractor channel; serves as the most direct public-market analog for valuation and operating benchmarking.

Others

• GAF Materials (Holcim): Largest North American roofing manufacturer and a key vendor partner for NCBP. Listed as an OTHERS given its supplier/manufacturer role rather than direct distribution overlap, but reference as a strategic channel relationship.
