repaired to a condition satisfactory for slates.

C. Contractor shall guarantee all material to be as specified. All work is to be

completed in a workmanlike manner according to standard practices. Any alteration

or deviation from these specifications involving extra costs will be executed only

upon written orders and will become an extra charge over and above the estimate.

PART 3 – MATERIALS

A. ROOFING UNDERLAYMENT

Contractor will provide a 30 lb. felt underlayment to be installed half-lapped, with

1” galvanized roofing nails, or other suitable fasteners, over existing or repaired

roof sheathing prior to the installation of the slate roofing. Along the bottom 36”

of the roof at the eaves, contractor will install the slate with a 4” headlap to

provide greater ice-dam protection.

B. SHEATHING REPAIR OR INSTALLATION

All roof decking (sheathing) installation, repairs, or replacement will be

completed using decking material the same as, or similar to, existing decking

material, but not to include laminated woods of any kind. No plywood roof

decking will be used. If existing roof decking has deteriorated in areas and must

be replaced prior to the installation of the new slate, such replacement will require

the additional charge of $XX/square foot of replaced roof sheathing.

C. NAILS AND FASTENERS

All nails, screws, and flashings used for the work shall be galvanically

compatible. For installing new slate, hard copper nails will be used, 11 gauge,

1.5” long.

D. FLASHING

1. All flashing shall be minimum 16 ounce copper.

2. Valley flashing will be 20 ounce, partially hardened copper, 16” wide, leaving an

exposed valley of 6”.

3. Ridge flashing will be 16 ounce copper ridge roll, fastened with 2.5” 10 gauge

copper nails or copper cleats.

4. Step flashings, chimney flashings and dormer aprons will be minimum 16 ounce

copper.

5. Flat-lock soldered copper roofing will be 20 ounce, partially hardened copper.

6. All copper is to be uncoated “red” copper.

E. SLATE

1. Slate shall be S1 Grade, [XX variety] slates, free of defects, with punched rather

than drilled nail holes. The slates will be blended from all pallets at once during

installation.

2. All slate shall be from the same source: XX

3. Slate shall be laid with a minimum 3” head lap. Head lap will not be decreased,

but will be increased to 4” along the bottom 3’ of the roof at the eaves (measured

vertically). Side-laps will be maintained at a minimum of three inches, if possible.

4. Slate shall be hard, dense, sound rock of uniform thickness, approximately 3/16”-

1/4” thick, with square cut edges.

5. Eave slates shall be laid to provide a 1.5” projection beyond the furthest extent of

fascia. Rake edge (gable end) slates shall extend 1”.

PART 4 – EXECUTION

A. INSPECTION

The contractor shall inspect all surfaces prepared for slating. Surface shall be

sound and free of all defects that may cause damage to roofing felt, flashing and

slate. Any defects in the decking shall be corrected prior to installation at an

additional charge of $XX/square foot of replaced decking.

B. INSTALLATION

1. Underlayment

a. A double layer (half-lap) of 30 lb felt underlayment will be installed over

all deck sheathing prior to slate installation.

b. Underlayment shall be laid in horizontal layers with joints lapped toward

eaves or drains and ends overlapping at least 3 inches.

2. Slating

a. Slates are to be standard thickness, X” wide by X” long, [type] from

[source] Quarry.

b. All standard slates shall be fastened with two copper 11 gauge roofing

nails, 1 ½” long.

c. The slate shall project 1.5” at the eaves. All standard field slates will be

installed with a 3” head lap following chalk lines marking the top edge of

each course of slates. Each course shall break joints laterally by a

minimum of 3”, if possible, with the underlying or overlying course.

Slates at the eaves shall be doubled by using a slate starter course that is

canted 3/8” to ½” by a solid (not laminated) wood [or copper] cant strip.

[Note: thickness of cant is dependent on thickness of the slates.] The first

course of slate shall be laid over the slate starter course so that the drip

edges of both courses are flush. The starter course should be laid back side

facing up to allow the edge bevel to merge flush with the edge bevel of the

first course (which is laid back side facing down, as are all other slates on

the roof, except the starter course).

d. Slates will be neatly fitted around any pipes, ventilators, and other roof

penetrations. Slates overlapping sheet metal shall have the nails placed so

as to minimize puncturing the metal.

e. Slating nails shall not be driven in so far as to produce an excessive strain

on the slates and shall instead be driven to a depth such that the nail heads

lie within the counter-sunk nail hole and do not rub excessively against the

overlying slates.

f. Any exposed nail heads will be sealed with a construction grade, clear or

matching color caulk such as Geocel 3300 or GE Silicon II.

g. Contractor must make all reasonable efforts to avoid walking on the slates

during the installation process. Upon completion, all slate shall be sound,

unbroken, un-cracked, whole and clean, showing no exposed roof cement.

Individual slates that must be installed in the field of the roof after the

installation is complete, such as where a roof bracket had been removed or

where a repair has been made, shall be installed using stainless steel or

copper slate hooks or copper or stainless steel roofing nails covered with

appropriate bib flashings.

D. CLEANING UP

a. Tools, equipment, surplus materials, slate-scraps, and debris resulting

from the slate roof installation shall be organized and cleaned up, or

removed and disposed of by contractor, on a daily basis.

b. It is possible that dust and dirt may infiltrate into the attic space during

installation or removal of roofing slate. This is particularly true during

removal of old slate and felt. Contractor will not be held responsible for

clean up of attic areas or any other interior areas. Building owner is

advised to remove any valuable items from the roof or attic spaces and/or

to cover such items with plastic, tarps, or other suitable covering.
