Project Wilderness Ranger District 3 Roof Replacements General Information

1.0 Scope of Work

The U.S. Forest Service, Wilderness Ranger District (Mimbres, NM), requires full roof replacement on three historic structures:

1. Big House — Metal roofing system (contractor‑provided; profile must match historic appearance)

2. Smaller House — Synthetic cedar‑look shakes (contractor‑provided; profile must match historic appearance)

3. Shower/Laundry Building — Synthetic cedar‑look shakes (contractor‑provided; profile must match historic appearance) All work shall preserve the historic character of the structures in coordination with SHPO, in accordance with the Secretary of the Interior’s Standards, and National Park Service Preservation Brief 4 (roofing in historic structures)

2.0 Background

The Wilderness Ranger District maintains several historic administrative and support facilities located in Mimbres, New Mexico, that contribute to the historic character and operational continuity of the site. The existing roofing systems on the Big House, Smaller House, and Shower/Laundry Building have reached the end of their service life and are exhibiting deterioration, weathering, and reduced long-term reliability. Roof replacement is necessary to protect the structures from continued moisture intrusion, preserve the integrity of the buildings, and maintain safe and functional occupancy.

Because these structures possess historic character and are subject to heritage preservation considerations, the replacement roofing systems must maintain the historic visual appearance of the original structures while incorporating durable modern materials and installation methods. All work shall be performed in coordination with applicable SHPO requirements and in a manner consistent with the Secretary of the Interior’s Standards for the Treatment of Historic Properties.

The project includes installation of a historically appropriate metal roofing system on the Big House and synthetic cedar-look shake roofing systems on the Smaller House and Shower/Laundry Building. Synthetic shake materials shall closely replicate the historic cedar shake appearance, including profile, texture, exposure, and color characteristics, while providing improved durability, fire resistance, and reduced maintenance requirements appropriate for Forest Service facilities.

The intent of this project is to preserve the historic architectural character of the site while ensuring the buildings remain weather-tight, code-compliant, operationally functional, and maintainable for long-term Forest Service use.
