Folsom's architectural history reflects its agricultural roots and evolving community needs. In its early years, the area was dotted with simple wooden farmhouses and barns, constructed using locally available timber. These structures typically featured steeply pitched roofs covered with wood shingles or shakes, designed to handle the area's frequent rain and humidity.

As the village developed in the mid-20th century, new architectural styles began to emerge. Influenced by broader trends of the time, ranch-style homes became popular, characterized by their single-story layouts and open floor plans. These homes often had low-pitched roofs with asphalt shingles, a practical choice for their cost-effectiveness and ease of maintenance.

In recent decades, Folsom has seen a blend of traditional and modern architectural styles. Many newer homes incorporate elements of Southern architecture, such as large porches and gabled roofs, while also embracing contemporary design principles focused on sustainability and energy efficiency. Metal and composite roofing materials are now common, valued for their durability and resilience in the local climate.
