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.

Original Life Expectancy of Woodruf Shingles

While we have observed statements that the original life expectancy of Woodruf shingles was 30 years, 40 years, and even 50 years, (including some original Woodruf shingle brochures), our sources principally indicate that Woodruf shingles were marketed with a 30 year life expectancy. As of this artcle's last update (October 2010) there is no warranty service remaining on this roofing product.

Composition of Woodruf Fiberboard Shingles

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.

Intended Use of Woodruf Fiberboard Roof Shingles

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.

Replacements for Masonite™ Woodruf Shingles?

Question: what is an appropriate replacement for Woodruf shingle roofs?

I own a roofing company, have an insurance adjuster background, and also do roof inspections for insurance companies. My opinion on the Woodruf product is to replace it with a 30 year laminate shingle. I have another roofing company stating the Woodruf product was marketed as high quality and that it was expensive. Thus a higher quality shingle should serve as a replacement. They do not agree with my replacement with the 30 year laminate. This particular Woodruf roof is in considerably good shape considering the product, but replacement hinges on one shingle found missing during my inspection. Do you know of any Woodruf shingle replacements available, like say one shingle?

Lastly, what supportive document do you have regarding the marketing of Woodruf shingles as a 30 year product that you can share with me? - Anon.

Reply: High quality laminate asphalt shingles or cedar wood roofing?

To replace a single roof shingle for the case you mention, you might try

• Removing a shingle in good condition from an area on the roof that is not visible from the ground, repairing the spot of removal using another durable roofing product.
• Using a slate of similar color and thickness. You may be able to install the replacement in either case using slate hooks to minimize the disturbance to surrounding roofing.

A more general question has been brought by several readers about the appropriate roofing material to use when the entire Woodruf shingle roof is ready for replacement.

Our OPINION is that a high quality laminate roofing shingle would be an appropriate replacement for Woodruf in that case.

It may be a difficult argument to claim that the original Woodruf roof met the quality and durability expected by the building owner and that therefore its replacement should be a product of the same original cost. The durability and quality of Woodruf roofing that was anticipated by the manufacturer, roofers, and consumers was unfortunately not met, and is brought into question by the early failure issues that are well documented.

We would welcome suggestions about top-end in appearance and durability roofing products that meet the original life-expectancy claimed for the Woodruf product (and that deliver that performance).

Slate? Not likely to be technically possible due to weight and structure issues.

Wood? A close cosmetically similar roof would be red cedar shingles but there may be local fire and code issues, maintenance costs, etc. that won't appeal to some building owners, not to mention the short roof life if you install wood shingles over solid plywood decking - so is it cost justified to redesign the roof deck or add venting?.

Perhaps cement roofing tiles? Weight and appeaarnce issues. Do you know what product the other roofer wants to install?

All of the Woodruf roofing material information we have readily found is published at this website.

We are looking for early Woodruf Roof Shingle marketing brochures that included life expectancy statements - CONTACT us if you find such documents.

About the anticipated product life, we have seen life expectancy claims of 30, 40, and even 50 years but not a public document with those numbers.

We would welcome your views and added suggestions

Frequently Asked Questions (FAQs) about Masonite or Woodruf Roof shingles

Question: how do I get the life of mymy Woodruf or Masonite Roof Shingle, where is my warranty & where is the explanation of the replacement roof choice and its life expectancy

How do I get warranty info or any documentation explaining the life expectancy or comparable replacement for Masonite Woodruf? - Ben 2/27/2013

Reply:

Ben,

The contact information for the manufacturer of your roof is in the article just above. If you can provide the product name of what's on your roof and a reasonably accurate guess at when the roof was installed, the company should have no trouble giving you a copy of the appropriate warranty. It's important to have a good idea of when the roof was installed or when the material was manufactured because like many manufacturers, roofing product manufacturers may offer different warranty terms for products made during different eras.

If you are asking about the life expectancy of a replacement product you'd need to specify what the product is.

If you are asking about the existing product, given the failures already reported, and with not a shred of information about your particular installation, with respect, I'm doubtful that a guess about the remaining life of your roof would be more than wild arm-waving.

Most home inspectors, seeing a known-problem-product will be reluctant to bet their house and kids'education money on promising you any remaining life whatsoever, or more accurately, would report on the evidence of current leakage and give a warning that you need to be prepared (financially) to replace the roof at any time

If you can provide the product name of what's on your roof and a reasonably accurate guess at when the roof was installed, the manufacturing company should have no trouble giving you a copy of the appropriate warranty.

Watch out: It's important to have a good idea of when the roof was installed or when the material was manufactured because like many manufacturers, roofing product manufacturers may offer different warranty terms for products made during different eras.
