Roofing, Siding, and Insulation Material Merchant Wholesalers
Description
The roofing, siding, and insulation material merchant wholesalers play a critical role in the construction supply chain by sourcing and distributing essential building components to various sectors of the industry. These establishments focus on nonwood products such as asphalt shingles, wood-look composite siding, and a wide array of fiberglass or cellulose insulation materials. Their primary business activity involves purchasing large quantities of raw materials or finished goods from manufacturers and storing them before selling them to other businesses rather than to end consumers. Typical operators include independent regional distributors, large national conglomerates, and multi-location chain stores that manage vast inventory levels across different product lines. Many of these companies specialize in specific regions, allowing them to adapt quickly to local building codes and climate requirements which dictate material choices. The scale of operation often spans hundreds of thousands of square feet of warehouse space with extensive loading docks to facilitate rapid order fulfillment for home builders, commercial contractors, and specialty renovation firms. This sector remains vital because it ensures that construction projects across the country receive high-quality materials necessary for energy efficiency, weather protection, and structural integrity. Without the network of these wholesalers, the flow of durable goods from factory floors to job sites would be significantly disrupted, leading to delays and increased costs throughout the broader construction economy.
Hierarchy
| Code | Title | Description |
|---|---|---|
| 42 | Wholesale Trade 2-digit sector | The Sector as a Whole The Wholesale Trade sector comprises establishments engaged in wholesaling merchandise, generally without transformation, and rendering services incidental to the sale of merchandise. The merchandise described in this sector includes the outputs of agriculture, mining, manufacturing, and certain information industries, such as publishing. The wholesaling process is an intermediate step in the distribution of merchandise. Wholesalers are organized to sell or arrange the purchase or sale of (a) goods for resale (i.e., goods sold to other wholesalers or retailers), (b) capital or durable nonconsumer goods, and (c) raw and intermediate materials and supplies used in production. Wholesalers sell merchandise to other businesses and normally operate from a warehouse or office. These warehouses and offices are characterized by having little or no display of merchandise. In addition, neither the design nor the location of the premises is intended to solicit walk-in traffic. Wholesalers do not normally use advertising directed to the general public. Customers are generally reached initially via telephone, in-person marketing, or by specialized advertising that may include Internet and other electronic means. Follow-up orders are either vendor-initiated or client-initiated, generally based on previous sales, and typically exhibit strong ties between sellers and buyers. In fact, transactions are often conducted between wholesalers and clients that have long-standing business relationships. This sector comprises two main types of wholesalers: merchant wholesalers that sell goods on their own account and agents and brokers that arrange sales and purchases for others generally for a commission or fee. (1) Establishments that sell goods on their own account are known as wholesale merchants, distributors, jobbers, drop shippers, and import/export merchants. Also included as wholesale merchants are sales offices and sales branches (but not retail stores) maintained by manufacturing, refining, or mining enterprises apart from their plants or mines for the purpose of marketing their products, and group purchasing organizations primarily purchasing and selling goods on their own account. Merchant wholesale establishments typically maintain their own warehouse, where they receive and handle goods for their customers. Goods are generally sold without transformation, but may include integral functions, such as sorting, packaging, labeling, and other marketing services. (2) Establishments arranging for the purchase or sale of goods owned by others or purchasing goods, generally on a commission basis are known as business-to-business electronic markets, agents and brokers, commission merchants, import/export agents and brokers, auction companies, group purchasing organizations (acting as agents), and manufacturers' representatives. These establishments operate from offices and generally do not own or handle the goods they sell. Some wholesale establishments may be connected with a single manufacturer and promote and sell the particular manufacturer's products to a wide range of other wholesalers or retailers. Other wholesalers may be connected to a retail chain, or limited number of retail chains, and only provide a variety of products needed by that particular retail operation(s). These wholesalers may obtain the products from a wide range of manufacturers. Still other wholesalers may not take title to the goods, but act as agents and brokers for a commission. Although, in general, wholesaling normally denotes sales in large volumes, durable nonconsumer goods may be sold in single units. Sales of capital or durable nonconsumer goods used in the production of goods and services, such as farm machinery, medium- and heavy-duty trucks, and industrial machinery, are always included in wholesale trade. |
| 423 | Merchant Wholesalers, Durable Goods 3-digit subsector | Industries in the Merchant Wholesalers, Durable Goods subsector sell capital or durable goods to other businesses. Merchant wholesalers generally take title to the goods that they sell; in other words, they buy and sell goods on their own account. Durable goods are new or used items generally with a normal life expectancy of three years or more. Durable goods merchant wholesale trade establishments are engaged in wholesaling products, such as motor vehicles, furniture, construction materials, machinery and equipment (including household-type appliances), metals and minerals (except petroleum), sporting goods, toys and hobby goods, recyclable materials, and parts. Agents and brokers primarily engaged in wholesaling durable goods, generally on a commission or fee basis, are classified in Subsector 425, Wholesale Trade Agents and Brokers. |
| 4233 | Lumber and Other Construction Materials Merchant Wholesalers 4-digit industry group | This industry group comprises establishments primarily engaged in the merchant wholesale distribution of lumber, plywood, millwork, and wood panels; brick, stone, and related construction materials; roofing, siding, and insulation materials; and other construction materials, including manufactured homes (i.e., mobile homes) and/or prefabricated buildings. |
