Masonite shingles information website:

This website provides detailed information about Masonite™ Woodruf™ fiberboard roof shingles and includes advice for home inspectors, home buyers, and homeowners where these roofing products are used.

Several hardboard-based and fiber cement based roofing products have not performed as well as originally anticipated, experienced early failure, and were the subject of roof warranty claims. Masonite Woodruff™, Cemwood™, Hardishake/Hardislate™, CalShake™ and Fire Free™ are examples of product names that have suffered these problems.

Wood Fiber Based Roofing, including Masonite Woodruf™ Fiberboard Roofs: inspection, failures, warranty information, replacement

Woodruf roof shingle panel underside (C) Daniel FriedmanThis article explains wood-fiber based shingle failures such as Masonite Woodruf fiberboard shingle life, failures, and warranty claims for this and other wood-fiber roofing products.

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 2014) 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

Woodruf shingle flashing (C) Daniel Friedman

Between every Woodruf roofing panel and its abutting neighbor an alumium flashing strip was installed under the butt joint.

You can see this special Woodruf flashing strip at the bottom of the butt joint in the lower center of our photograph (left).

This strip should be 12" in length and should extend to the head or upper edge of the shingle. Flashing for shingle butt joints provided by the manufacturer included a lip at the upper edge to keep the strip from sliding out of place.

A raised ridge in the center of each flashing section acts as a spacer and allows for thermal expansion of the shingles without buckling the roof.

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

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

Masonite™ Woodruf Shingle Class Action Lawsuit Settlement Information for Homeowners

Also see MASONITE WOODRUF® ROOFING OR MASONITE OMNIWOOD® SIDING LAWSUIT SETTLEMENT NOTICE - PDF file

If you qualify as an Eligible Claimant, you may be entitled to recover under the Settlement. However the claims period expired on January 6, 2009.

To be an Eligible Claimant, you must:

  1. Own property in the United States or its Territories on which Woodruf roofing has been incorporated and installed since January 1, 1980, and have not assigned the claim regarding the alleged damage caused by Woodruf;
  2. Be a subsequent purchaser of such property and have properly documented assignments determined to be valid under the Settlement; or
  3. Own or have formerly owned such property and have made Prior Un-Reimbursed Expenditures as defined by the Settlement.

Eligible Claimants do not include persons, associations or entities who made claims or filed lawsuits against Defendants other than in the Smith class action, if they were represented by counsel other than Plaintiffs' Class Counsel in the Smith class action, and their claims or lawsuits were resolved by payment based upon the entire square footage of Masonite Woodruf roofing on the structure, full release or judicial action

Masonite Woodruf Siding Claims Period: now expired

The Masonite Woodruf Shingle / Siding settlement allowed 10 years for filing defective hardboard siding claims by providing proof of ownership and a separate verification of the siding as Masonite. Claims were filed beginning in the middle of 1998.

The settlement class was defined as all individuals across the United States who own a house or other structure upon which Masonite hardboard siding, manufactured since 1980, has been installed. More usefully: the class action pertained to owners who had Masonite siding installed between January 1, 1980 and December 31, 1989. Claims could thus be filed until the 15th of January 2008 or by other sources the Woodruf shingle claims period expired on January 6, 2009.

Current information about Masonite Woodruf settlement and claims assistance was available by calling 1-800-256-6990.

Watch out: This information was originally available on the Internet at: http://www [dot] masoniteclaims [dot] com but we have disabled the link because it currently hosts a "made for ad-sense" advertisement page offering no useful information for homeowners.

If you are experiencing a problem or failure with any brand of Hardboard Siding or other wood fiberboard siding products see SIDING HARDBOARD.

Masonite Siding on Homes For Which Claims Have Not Been Made

If you own a home with Woodruf siding installed and did not file a claim, depending on when your siding was installed, the remaining portion of its 25-year original warranty could remain in effect.

If you own a home with other Masonite siding products installed, such as Omniwood siding, the class action, settlement, or warranty coverage periods are different: that action pertained to Omniwood siding installed between January 1, 1992 and January 6, 1999. Omniwood siding is identified by a stamp on the siding back: "Masonite Omniwood" and there may be date data. This is a wood fiber siding product.

There were other legal filings including an appeal, cases involving people who elected to opt out of the original Masonite class action group, and related cases. There were also reports of mishandling of funds and possible fraud by companies offering assistance in filing Masonite siding claims. So a generic web search will yield a drown-in list of articles and web pages. I will include the legal citation as a source for more information.

Reader Questions: how do I determine the life expectancy of my 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

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.
