Roaring Spring is a borough in Blair County, Pennsylvania, United States. The population was 2,392 at the 2020 census. It is allowance of the Altoona, PA Metropolitan Statistical Area

Roaring Spring was established almost the huge Spring in Morrison’s Cove, a tidy and dependable water source necessary to the operation of a paper mill. Prior to 1866, when the first paper mill was built, Roaring Spring had been a grist mill hamlet similar to a country buildup at the intersection of two rural roads that gain to the mill near the spring. A grist mill, powered by the spring water, had operated at that location in the past at least the 1760s. After 1867, as the paper mill expanded, surrounding tracts of land were acquired to accommodate housing develop for additional workers. The formalization of a town plan, however, never occurred. As a result, the seemingly random street pattern of the historic district is the product of hilly topography, a little network of pre-existing country roads that converged near the enormous Spring, and the property lines of next-door tracts that were acquired through the years for community expansion. The arterial streets of the district are now East Main, West Main, Spang and Bloomfield, each of which leads out of the borough to surrounding townships. Two of these streets — Spang and East Main — meet subsequently Church Street at the district’s main intersection called “Five Points.” The boundaries of the district really include those portions of Roaring Spring Borough which had been laid out for enhancement by the in front 1920s. This Place encompasses 233 acres (0.94 km) or 55 percent of the borough’s Place of 421 acres (1.70 km²). Since the district’s time of significance extends to 1944, most of those buildings erected after the 1920s were built as infill within the areas already subdivided by the 1920s. In the prematurely 1960s, the Borough began to annex sections of neighboring Taylor Township, especially to the east all but the then extra Rt. 36 Bypass.

Daniel Mathias (D. M.) Bare laid out Roaring Spring’s first 50 building lots in 1865 after he and two partners established to locate the region’s first paper mill near the spring. These lots were located within and approximately the so-called village “triangle” defined by West Main, Spang, and East Main Streets. By 1873, the borough contained more or less 170 lots and 50 buildings, which included the paper and grist mills, three churches, a company store, a schoolhouse, and one hotel. The population stood at roughly 100. The triangle remained the industrial, commercial and retailing core of the town until 1957 once the bypass of Main Street, PA Rt. 36, was built to the east of town through Taylor Township. As is valid of many American small towns, many village merchants along with further businesses have before relocated to the additional highway. The village core retains lonely a few shops and professional offices, but still holds the Roaring Spring Blank Book Company and Roaring Spring Water Bottling Company, all of the historic church buildings, the public library(formerly the Eldon Inn), the borough building, the post office(earlier moved from farther taking place East Main St.). The elementary school (former junior-senior tall school)was demolished in 2010.
