Inspection of Masonite Woodruf™ Fiberboard Roofs

Woodruf™ roof shingles, a fiberboard roofing product, were a Masonite™ roofing product consisting of "pressure bonded fibers designed to resemble natural cedar roofing" sold in the United States into the 1990's and have also been found installed on homes in Canada.

Masonite Woodruf shingles were the subject of a class action lawsuit and settlement concerning the durability of this roofing product - we discuss the Woodruf roofing class action settlement below. However the Woodruf shingle claims period expired on January 6, 2009.

Our photo (left) shows how easily a Woodruf roof shingle panel can be identified if you have access to its under-side.

The roofing shingle product was produced in four-foot sections that were 12" wide and with a nominal thickness of 7/16". The actual thickness varies due to raised ridges that give Woodruf shingles the appearance of a wood shake or shingle.

Our sources indicate that Woodruf shingles were marketed with a 30 year life expectancy. As of this artcle's last update (May 2009) there is no warranty service remaining on this roofing product.

The Woodruf™ shingle fiberboard was treated with a water repellant and a bonding agent to permit outdoor exposure. This product is softer than Masonite's hardboard products and to remain durable required an installation that permitted good roof drying (similar to the requirement for wood shingles or shakes). This is particularly true because the factory edges as well as any cut edges made during installation were not sealed.

Masonite Woodruf roofing was intended for steep slope roofs and should not be installed on slopes lower than 4" of rise in 12" of run (a 4/12 roof). The shingles were to be installed over roofing felt on a sound roof deck, with a 9" shingle exposure and requiring eight nails per roofing panel.

Special Flashing Required for Woodruf Roofing Shingles

Common Defects and Signs of Deterioration found on Masonite Woodruf Roofs

Buckling Woodruf shingle panels may occur if the proper aluminum flashing strips were not used at the butt joints Cut edges in the Woodruf shingles, made to fit to rake edges, valleys, and around chimneys or roof penetrations are more likely to be deteriorated from weather exposure and water. Swollen, delaminating Woodruf shingle material becomes soft and easily crumbles, suggesting that an on-roof inspection may further damage already-fragile or worn materials. Our photo (left) shows typical softening and aging at the edge of a Woodruf shingle panel. Thick, swelling Woodruf shingles may be found anywhere in the roof area, indicating material that is at the end of its life.

Moss, lichens, and deterioration caused by shading from overhanging trees and tree debris can substantially reduce the life of any roofing product, particularly one that may absorb moisture, swell, and delaminate when wet Our photo (left) shows moss and lichens growing in a butt joint between two Woodruf roof shingle panels. It appears that the desired special flashing strip may have been omitted at this location as well.
