A steep challenge

Knox Roofing installs a shingle roof system on a historical mansion

Kelly Thompson Ranch in Watsonville, Calif., was built in 1851 as a private residence and served as a venue for special events. Although the ranch's grounds continue to be used for private events, the historical mansion has been vacant for 50 years because of leaks in the roof.

The mansion features a complex steep-slope roof with multiple levels and various slopes. So when the owners of Kelly Thompson Ranch decided to replace the roof on the historical structure, it was important to find a contractor who could rise to the challenge.

A complex design

The owners of Kelly Thompson Ranch approached Knox Roofing, Scotts Valley, Calif., and asked it to install a fiberglass-reinforced architectural shingle roof system on the mansion.
