About Penfield & Sons, Inc.

Penfield, the business has grown into a second-generation operation, with a third generation currently being brought into the fold.

Robert G. Penfield built the company on a foundation of quality craftsmanship and the belief that a home is more than just a structure — it's where families live and grow.

Roofing Services in Western Massachusetts

Penfield & Sons, Inc. offers roof replacement services tailored to the demands of the Western Massachusetts climate. Homeowners in this region deal with heavy snowfall and ice in winter, as well as strong winds and rain throughout the year. The company provides:

  1. Detailed roof inspections
  2. Expert advice on replacement options
  3. Installation using materials suited to local weather conditions

Whether a roof has deteriorated over time or a homeowner is planning a proactive replacement, Penfield & Sons, Inc. works to deliver results that hold up through the seasons.

Siding, Insulation, and Replacement Windows

Beyond roofing, Penfield & Sons, Inc. also offers exterior improvement services including insulated vinyl siding and home replacement windows.

The company installs Mastic insulated vinyl siding, which adds an extra layer of insulation to a home's exterior. This type of siding helps reduce heat transfer between the interior and exterior of a home, contributing to improved energy efficiency and more consistent indoor comfort throughout the year.

Home replacement windows are another service offered by the company. New windows can provide a range of practical benefits for homeowners, including:

  1. Improved energy efficiency — better insulation can help lower heating and cooling costs
  2. Enhanced curb appeal — updated windows improve the exterior appearance of a home
  3. Reduced maintenance — modern vinyl or fiberglass windows typically require less upkeep than older wooden frames
  4. Increased comfort — replacement windows help seal against drafts and maintain steadier indoor temperatures
  5. Noise reduction — newer windows can provide better sound insulation
  6. Improved security — modern windows often include stronger locks and more durable materials
  7. UV protection — many current window options include coatings that help prevent fading of interior furnishings

Penfield & Sons, Inc. has been serving the Greenfield area and surrounding Western Massachusetts communities for over five decades. As a multi-generational contractor, the company brings long-standing local experience to residential building and renovation projects of varying scope.

"They did a great job putting on my siding, gutters and garage door. The following year we damaged a window sill putting in an air conditioner and they returned to fix it in a couple of days, during their busy time. They are very thorough and professional."
