In my second “rotted slate” photo below, I’m demonstrating that my weak puny thumb and forefinger are engough to smush this red slate into mud.

My third end-of-life slate photo shows the result: the slate is a handful of fragile chips and slivers.

This red slate, probably from the Granville NY quarry, was also wet through to the touch. A few of these slates were on the ground along a barn on the FDR estate, the rest were still on the roof.

We strongly advise inspectors not to walk on slate roofs. Risks include falling – very slippery, and extensive damage to the slates.

Slate Tile Roof Life Expectancy: How Long Does a Slate ...

Although slate quarrying was not common in the United States until the latter half of the nineteenth century, slate roofing is known to have been used prior to the Revolution. Archeological excavations at Jamestown, Virginia,have unearthed roofing slate in strata dating from 1625-1650 and 1640-1670. Slate roofs were introduced in Boston as early as 1654 and Philadelphia in 1699. Seventeenth century building ordinances of New York and Boston recommended the use of slate or tile roofs to ensure fireproof construction.

Architectural pattern books of the mid-19th century awakened Americans to the availability and quality of slate for roofing purposes. Drawing: Design XX, “A French Roof House,” in A.J. Downing’s Victorian Cottage Residences.

Quality Of The Installation

How well the slate roof has been installed will also affect its lifespan. Older slate roofs were installed with iron or lower-quality galvanised steel nails that are very susceptible to weather corrosion, causing a problem called nail sickness. Slate roofs suffering from nail sickness are likely to have slipped and broken slates that allow water damage and reduce the lifespan of the roof.

Other common installation problems that can affect the lifespan of a slate roof are inadequate overlap of the tiles, poorly fitted flashing and poor sheathing materials in the roof underneath the slate.

How Long Does a Roof Last? A Guide for Homeowners

hi, what is the difference between canadian roofing slates and welsh slates .

Reply:

John you must know that the names refer to where the roofing slates originate.

Canadian roofing slates are made from slate quarried in Quebec or possibly Newfoundland, and sold by a variety of companies. According to the National Slate Association,

Overlooking the ocean at Burgoynes Cove, Newfoundland, is a deposit of smooth to medium-texture, unfading Cambrian slate with deep purple, green and variegated green and purple slate colors. The purple slate is very similar in color to Welsh Purple from England. Production of roofing slate from this quarry has been intermittent since the early 1900s.

The Glendyne Quarry in St. Mark du Lac Long, Quebec, Canada, is the largest roofing-slate producing facility in North America and one of the largest in the world. Their unfading black slate is currently produced for the European and North American market and is marketed in North America as North Country Unfading Black.

The first production from this vein of slate occurred in the early 1900s. This smooth-textured slate is easy to cut and has a consistent black color with subtle vertical shade markings. – slateassociation.org

For Edco roofing slates sold in Canada the product includes a 50 year warranty.

Welsh roofing slate is described by welshslate.com which I quote as well, noting that this is also marketing literature mixed with useful facts:

Where Does Slate Come From Return To Top

Slate is a fine grained, crystalline rock derived from sediments of clay and fine silt which were deposited on ancient sea bottoms. Superimposed materials gradually consolidated the sedimentary particles into bedded deposits of shale. Mountain building forces subsequently folded, crumpled, and compressed the shale. At the same time, intense heat and pressure changed the original clays into new minerals such as mica, chlorite, and quartz. By such mechanical and chemical processes bedded clays were transformed, or metamorphosed, into slate, whole geologic ages being consumed in the process. Slates vary in composition, structure, and durability because the degree to which their determinant minerals have been altered is neither uniform nor consistent.

The adaptation of slate for roofing purposes is inextricably linked to its genesis. The manufacturing processes of nature have endowed slate with certain commercially amenable properties which have had a profound influence on the methods by which slate is quarried and fabricated, as well as its suitability for use as a roofing tile.

What To Consider When You Are Replacing A Roof

One important thing to consider when you are choosing a roofing system or purchasing a new property is the resistance of the roof to wind uplift, which is the suction effect created by wind forces as the air flows parallel to the surface of the roof.

When a gust of wind hits the side of a house or other building, some of that air moves upwards across the roof, creating a pressure differential that can blow off or damage shingles or tiles, or even entire sections of the roof altogether.

Roofing systems are rated based on the amount of wind uplift they can withstand measured in miles per hour.

If you live in a particularly windy area or one that is prone to tornadoes or hurricanes, youll want to ensure that you go for a higher rating for wind uplift to avoid a wind damage roof.

Youll also want to consider other factors before replacing your roof or purchasing a property the age of the roof, how many layers of shingles there are, and whether the roof is properly braced and ventilated.

A roof inspection performed by a professional can help you answer these questions and more, and you can also visually examine the roof yourself for curling or buckling shingles, missing shingles, damaged shingles, damage to the flashing or seals around the chimneys, skylights, or dormers, granules or debris in the gutters or around the ground near your home, and other signs of future problems.

Life Expectancy / Durability Of Different Roofing Slates

Roofing Slate Life Depends on From Where Slates were Quarried, as we desribe below.

Life expectancy of Virginia Buckingham roofing slate

Darker gray “Buckingham” slates from Virginia are considered a durable high-quality material which, properly maintained, can have a near indefinite life. Average life of these slates is 175 years.

The Old House Journal, April, 1983 p. 57

Life expectancy of Vermont roofing slate

Vermont slate roofs, with proper maintenance, can last indefinitely.

Steven Trapasso, personal communication. Also the Old House Journal April 1983 rates Vermont slates as having a 175 year life.

Such roofs should be maintained, not replaced.

With proper maintenance such an asset may be continued for an indefinite period. Inspectors who do not know the composition and source of slates would not want to condemn, except in the worst of circumstances, a Vermont slate roof.

Typical life for Pennsylvania slate roofs is 40-50 years. These life expectancies are general experience with the material and do not consider installation or environmental factors which vary from one building to the next.

Slate is one of the most aesthetically pleasing and durable of all roofing materials. It is indicative at once of the awesome powers of nature which have formed it and the expertise and skill of the craftsman in handshaping and laying it on the roof. Installed properly, slate roofs require relatively little maintenance and will last 60 to 125 years or longer depending on the type of slate employed, roof configuration, and the geographical location of the property. Some slates have been known to last over 200 years. Found on virtually every class of structure, slate roofs are perhaps most often associated with institutional, ecclesiastical, and government buildings, where longevity is an especially important consideration in material choices. In the slate quarrying regions of the country, where supply is abundant, slate was often used on farm and agricultural buildings as well.

Although slate replacement roofs are expensive, the superiority of materials and craftsmanship will give years of continued service. If amortized over the life of the roof, the replacement cost can be very reasonable. Photo: NPS files.

Why Consider A Slate Roof Alternative

People who love the look of slate shingles, but back away due to their costs and weight, find realistic options with synthetic slate products. Why? Because some smart manufacturers have actually taken into consideration the pros and cons of slate roofing and improved on what Mother Nature offers.

Heres an example. Real slate roofs are not immune to the ravages of time, or hail. Tiny fissures make natural slate susceptible to damages caused by freeze and thaw cycles. Composite slate products dont have these concerns. They defy the elements for decades to provide enduring quality and worry-free beauty on a roof.

In addition, synthetic slate shingles shine when it comes to helping protect a home. At DaVinci Roofscapes, we craft our slate roof tiles to achieve a Class 4 Rating for impact resistance and a Class A Rating for fire resistance.

The Replacement Of Deteriorated Roofs Return To Top

Historic slate roofs should be repaired rather than replaced whenever possible. Before replacing a slate roof, check for isolated damage, corroded and worn flashings, leaky gutters, poor ventilation in the attic, and other possible sources of moisture. All too often slate roofs are mistakenly replaced when, in fact, they could have been effectively repaired. Deciding whether an historic slate roof should be repaired or replaced can be difficult and each roof must be judged separately.

If repair is not possible and a new slate roof must be installed, it is important to remember that more than just the replacement of the slate is involved. The old slate should be removed to prevent overloading of the roof timbers. Stripping should be done in sections, with felt installed, to avoid exposing the entire subroof to the weather. ln the process, rotted wood sheathing should be replaced and the roof timbers checked for signs of stress including deflection, cracking, and twisting. If such conditions are found, a structural engineer experienced in working with older buildings should be consulted. Other repairs, such as chimney repointing, which may require access to the roof should be completed before the new roof is put on.

Prior to a replacing a roof, historical documentation is gathered to determine the roof configuration. Photo: NPS files.
