About Us

Relationships For Years

When Ranch Roofing Inc. was born, with four employees two decades ago, the mission was to provide residential roofing services to home owners with only Ranch-Style homes. Bob O’Sullivan, President and founder, had the idea that if he could perfect a roofing system on one single style home, he could build customer relationships with consistent quality installs. Today Ranch Roofing has grown to a trusted expert on all styles of houses in Arlington, Cambridge, Lexington, Newton, Belmont and surrounding communities. We are proud to be known for quality work.

Install every roof as if it were your own

Our mission has not changed since those early days of “Ranch-Style only homes”. Even though Ranch Roofing has grown today to one of the largest residential roofing firms in Eastern Massachusetts Bob O’Sullivan still runs things same. Mr. O’Sullivan has preached for two decades, “install every roof as if it were your own.” We still do.

It is not “About Us.” It’s “About You.”

Since the roofing industry is comprised of local firms, not giant familiar institutions, it is difficult to choose the right firm without help from others who have recently experienced hiring one. Your good words and hundreds of customer referrals have informed local residents about what a fantastic company Ranch Roofing is. We love the buzz trending about us, but make no mistake, we work hard to maintain it. That’s Ranch Roofing. Our success is not about us, it’s about you.

Today Ranch Roofing fills an important void in the marketplace. The roofing industry has become price driven, because most homeowners are too inexperienced to grasp that roofing quality is more than just “the neighbor’s roof looks good.” There are a million ways to cut corners on a roof. We do not. In addition, Ranch Roofing remains a complete roofing company. We have a dedicated service department and have been awarded manufacturer certifications unique within our region. We would be no where without our wonderful customers. Ranch Roofing would like to say a sincere Thank You to all of our great customers: it’s been a great journey, and a promising future!
