able for a slate roof. This is due to the fact that the slate, if properly installed, will last 100 to 200 years, there-by requiring a roof deck substrate with a similar longevity. Glued wood materials are subject to delamination and premature deterioration well before a century or more of required service, especially in a roof construction sit-uation where they can be subjected to intense heat and intermittent moisture. The types of decks that have been tested and proven suitable for the longevity needed with slate roofing include 3/4” planed, kiln dried, board lumber, 1” rough-sawn lumber either air-dried or even green (undried), and 1.5” planed, kiln-dried lumber, of a variety of wood species. The roof decking boards can be either tongue-in-groove or standard, butted lumber. The half inch particle board currently used on the Sample residence roof is a cheap, unacceptable material not suitable to be used as a substrate for a replacement slate roof.
If this roof is properly reslated, a new layer of suitable decking material may be installed directly over the existing particle board if the particle board is free of moisture. A single-layer 30 lb.felt vapor barrier may be installed over the existing particle board prior to installing board lumber.
NAILS
Suitable nails for slate roof installations include smooth-shanked solid copper, solid stainless steel, and hot-dipped galvanized roofing nails. It is generally recommended that 11 gauge copper roofing nails be used on new slate roof installations.
Proper nail length is determined according to the formula: nail length = slate thickness x 2 + 1”, which assumes an approximate 1” roof deck. For a standard thickness slate such as is currently on the Sample resi-dence (3/16” to 1/4”), a proper nail length is 1.5”. Therefore, if this roof is reslated over a 3/4” to 1” board roof deck, the recommended nail would be a smooth-shank, 11 gauge, 1.5” solid, hardened copper nail.
The nails currently used to fasten the Sample roof slates are 1.75” electro-galvanized nails (Figure 6). They are too long and have broken out the back of the roof decking material during the installation of the slates (Figure 7). When this occurs, the effective grip length of the nail is reduced due to the effective thickness of the roof decking being compromised where the nail has broken out the back of the material. Furthermore, electro-galvanized roofing nails are not manufactured for longevity, but are designed for use with relatively short-lived asphalt shingles, not for use with slate. Electro-galvanized nails are not acceptable for slate roofs.
SLATE STARTER COURSE
The slate starter course is one of the most important courses on the roof. It lies underneath the first course at the drip edge and is not visible. However, more water flows over the bottom edge of the roof than any other area of the roof except the valleys, so it is critically important that this area of the roof be installed cor-rectly. The starter course prevents leakage between the exposed butted sides of the first course of slate. The starter course must be overlapped by the second course of slate by at least 3”. This is called the headlap and even greater headlap on the starter course is often recommended. On the Sample residence, the starter course is made of 8” slates turned sideways. These, therefore, extend up the roof 8”. Since the first course has an exposed face of 7.5”, this leaves only a 1/2” headlap on the starter course. In some areas, there is no headlap at all on the starter course (Figures 8 and 9).
Furthermore, the starter course is supposed to be installed face-down (the face of the slate is the side that shows the beveled edge, which is face-down on the starter course, but face-up on all other slates on the roof). By installing the starter slate face down, the beveled edge merges flush with the beveled edge of the first course of slate. Although this is a stylistic issue which does not affect the functionality of the roof, it is an indi-cation of whether the installer has experience with slate roof installations. Inexperienced installers tend to install the starter slate face up, as was done on the Sample residence (Figure 10).
In addition, it is important that the starter course and the first course be installed concurrently. This is to make sure that the side butt-joints of the starter course are overlapped laterally by the side butt-joints of the first course by at least three inches, which is the standard recommended lateral overlap between side-butts of over-lapping courses. When the starter course is installed independent of the first course, then the side butt-joints can overlap too closely, which is evident on the Sample residence in numerous places along the drip edges where lateral overlapping is nonexistent (Figures 10, 11 and 12).
In short, the slate starter course on the Sample residence is installed upside-down, with the wrong size Joseph Jenkins, Inc. — XXXXXX Residence Slate Roof Survey and Conditions Report — Page 2
slates and incorrect headlap, and lateral overlaps that incorrectly measure zero inches in many places (they should be 3”).
SLATES
The slates appear to be Chinese in origin, although they could be Spanish. They contain iron bearing inclusions that are leaching rust stains down the surface of the roof (Figures 13, 14, 15 and 16). This is unac-ceptable as it indicates a low quality slate that is defacing the roof. Good quality slate manufacturing process-es cull out slate shinglprocess-es that contain iron bearing inclusions.
The slates were cut with a diamond saw blade,leaving square edges as are typically found on floor tiles (Figures 17 and 19). Roofing slates always have beveled edges due to the manufacturing techniques utilized when the slates are made. The beveled edge shows on only one side of the slate — this side is always exposed on the roof, the only exception being on the starter slate. All cut edges should be cut in such a manner that a beveled edge, not a square edge, is left exposed in order to match the rest of the roof. This is easily achieved by cutting the slates with a common hand-held slate cutter, a tool readily available over the internet. The fact that this tool was not utilized by the installers of the Sample roof indicates that they were not equipped with the proper tools for such a job.
The slates are 16” in length and random in width. Slates that are 16” long must have an exposed face of 6.5” in order to maintain a 3” headlap throughout the roof, which is the standard recommended headlap for slate roofs with slopes above 6:12. Headlap measurements are determined by subtracting the desired headlap from the length of the slate, then dividing the remainder in two in order to determine the exposure of the slate. In this case, since a 3” headlap would be expected on a newly installed slate roof of these slopes, 16” (length of slate) - 3” (desired headlap) = 13”, divided by two = 6.5”, which is the necessary exposure of the slate (the exposure is the part of the slate shingle that you can see after the slate has been installed). On the Sample res-idence, the apparent typical exposure is 7.5” and the typical headlap is therefore 1” (Figures 18 and 19). Although this allows the roof to be installed with fewer slates, it greatly compromises the ability of the roof to be water tight. The headlap is the characteristic of the slate roof that prevents water penetration. Without sufficient headlap, the roof will leak like a sieve. One inch headlap is totally unacceptable. To make matters worse, there are areas on the Sample roof that have no headlap and even negative headlap up to -2” (Figures 20, 21A and 21B). These are areas where water can directly penetrate into the building. It is probably the underlayment (felt paper) and low annual rainfall that has prevented the roof from leaking profusely. It is only a matter of time before the faulty installation on this roof begins to destroy the structural interior.
Headlaps must be increased when the slope of the roof drops to 5:12 or less. 4:12 (four inches of hori-zontal run in five inches of vertical rise) is typically considered the lowest acceptable slope for slate roofs in America. The slope on the upper roof of the garage appears to be lower than 4:12, while the exposure on the slates that have been installed on these roof areas appears to be the same as on the other, steeper slopes. The upper garage roof should have, at the very least, a 4” headlap and therefore, 6” exposures maximum.
For more information about headlaps, see Addendum #2, page 40.
Many slates are falling off the Sample roof. Again, this is almost certainly a result of faulty installation. Slates are easily broken if walked upon during installation. When cracked or broken, they may not fall apart immediately, but may do so at a later time, often long after the installation contractor has been paid and left the site. The excessive number of broken, cracked or missing slates indicates damage to the slates during instal-lation, probably from foot traffic, which is a common problem associated with slate roofs that have been installed by inexperienced workers who are more accustomed to installing roofs that can be walked on during installa-tion, such as asphalt shingle, metal and low-slope roofs (Figures 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32).
There are numerous slates that have been face-nailed and/or caulked, probably in an attempt to repair the roof (Figures 33, 34, 35, 36, 37, 38, 39). Slate roofs cannot be properly repaired by face-nailing or caulking, as both methods of “repair” will leak. Proper repair methods include either the nail and bib method or the use of slate hooks, neither of which was used on this roof.
There are also deficient side-lap issues with the slates on this roof (Figure 39A is an example). Other procedural errors are evident on this roof (Figure 39B is an example)
FLASHINGS
Flashings are sheet metal joints between different roof planes and around roof penetrations. The flash-ings used on the Sample residence are almost entirely made from galvanized steel, a low-quality material sub-ject to rapid oxidation. Recommended flashings for slate roofs include copper or stainless steel due to their durability. The extreme longevity of standard slate shingles (generally 100 to 200 years) necessitates associat-ed flashings that have as great a longevity as possible.
STEP FLASHINGS
Any time a sloped roof surface abuts a horizontal plane such as a dormer wall, the slates must be tied into the wall by the use of step flashing. Step flashing is fabricated in such a manner that there is a single, sep-arate piece of flashing for each slate. Each step flashing is positioned underneath the bottom of each end slate with the bottom edge of the flashing aligned with the bottom edge of the slate. The flashings, like the slates, overlap in order to prevent leakage. The slates are not nailed through the flashings.
A single piece of flashing running underneath all of the end slates and up the horizontal plane will not work because the flashing will be punctured when the slate is installed and water will be able to migrate through the flashing and into the building. On the Sample residence, it appears that in all of the areas where step flash-ing is required, only sflash-ingle-piece flashflash-ings have been used (Figure 40).
CHIMNEY FLASHINGS
Chimneys protrude through roofs and must be rendered water-tight by the use of chimney flashings on all sides of the chimney that penetrate through the roof. On the Sample residence, there are chimneys that are either partially or completely devoid of flashings. Of particular concern are areas where the field of the roof drains directly into a vertical surface such as into the side of a chimney. This situation creates a “basin” or a “pan” where water can collect and leak into a building. It is critically important that these areas are flashed com-petently. However, on the Sample residence, a critical chimney basin area has been left with no flashing at all — only roofing paper (Figures 41and 42) .
TURRET FLASHING
The turret is supposed to be tied into the main roof with a metal flashing interface. Instead, on the Sample residence, the turret is tied into the main roof with only a roofing paper joint — no flashing has been used (Figures 43, 44A and 44B).
DRIP EDGE FLASHING
Drip edge flashing is not needed on most slate roofs. However, it is sometimes used, for example, for decorative purposes, or to cover raw ends of roof sheathing, or to integrate the roof edge with a built-in gutter system. In any case, if a drip edge is used, it is installed prior to the installation of the slates. A drip edge was installed on the Sample residence, but it was installed after the slate was installed, judging by the exposed nails toe-nailed into the drip edge underneath the bottom edge of the slate (Figures 45 and 46).
VALLEY FLASHING
Valleys are important flashing joints on slate roofs because they carry larger amounts of water than almost anywhere else on the roof. It is important that they are flashed correctly with a durable flashing materi-al. On the Sample residence, all valleys appear to be galvanized steel. Workmanship is poor, as evidenced by a caulk joint between two valleys (Figure 47). Such as joint should be either soldered, or folded properly, but not caulked.
PIPES AND VENTS
Pipes and vents penetrate through the roof surface and therefore create holes in the roof. They must be fitted with flashings that prevent leakage around the penetrations. Pre-fabricated pipe flashings are readily avail-able, yet it appears that none were used on the Sample residence. Instead, the pipes and vents were sealed with caulk or roof cement — a cheap, short-lived alternative to proper flashing (Figures 48 and 49). Properly flashed pipe penetrations are shown in Figure 50 (this is not on the Sample roof).
RIDGE AND HIP INSTALLATION
There are numerous ways to install finished ridges or hips on slate roofs. Such ridges can be made of slate, metal or ceramic tile. A “saddle” ridge is made of overlapping pairs of slate shingles installed along the ridge over the field slates. The saddle ridge slates should overlap each other by at least 50% in order to main-tain a double layer of slate at all times. This strengthens the ridge or hip and allows the slate to be installed in such a manner that the slate installation nails are covered by the overlying slate so they cannot leak. The best saddle ridges or hips include step flashing underneath each pair of ridge or hip slates. On the Sample resi-dence, the ridges and hips are finished in a modified saddle fashion, but the slates only overlap about 30% and not 50% (Figure 51). On the garage, the slates have almost no overlap at all and the fasteners, galvanized deck screws, are completely exposed (Figures 52 and 53). Ridge and hip butt joints are finished with caulk — no flashing is used.
For an illustration of a correct saddle style hip and ridge installation, see addendum #1, pages 38 and 39.
SUMMARY
In summary, to put it bluntly, the Sample residence slate roof should be condemned. Almost every detail of the installation and workmanship is poor, faulty or incomplete. The roof is a ticking time bomb that will cause leakage into the building that will begin soon, if it hasn’t already, and will increase in severity over time. This will become a very costly development considering the expense and workmanship that has apparently gone into the interior of the building.
Most of the deficiency in this roof installation is due to the slate installer. However, the sub-standard 1/2” OSB roof deck was apparently specified by the architect. The installation workmanship, choice of materials, and design specifications are all flawed on the Sample residence slate roofing system.
The roof should be replaced as soon as is feasible. It is recommended that the roof be replaced with a domestic S-1, standard thickness slate installed over minimum 3/4” solid board (not laminated) roof decking with 11 gauge 1.5” copper nails and copper flashings. Slate roofing installation information details can be found via the Slate Roof Bible, 2nd edition, and in the Traditional Roofing magazine or on its website (traditionalroof-ing.com).
