| THE WIRE WORKS, INC. TILE AND SLATE ROOF FASTENING SYSTEMS AND
RELATED HARDWARE FOR BETTER PERFORMING ROOFS!
The Wire Works, Inc. was founded in 1986.
At that time the founder and principal officer was already running a growing metal
manufacturing business in the San Fernando Valley in southern California. McMurray's
manufacturing Co., Inc. was founded in 1982, incorporated in 1984, and specializes in
processing metal products for the construction industry, most of which are used by the
roofing trade. Today McMurray's Manufacturing Co., Inc. ranks as one of the top three roof
tile metal birdstop (eave enclosure) producers in the United States. The founder and
principal officer, Patrick McMurray, has spent over 20 years working with roof tile
fastening systems and related hardware. As a result, The Wire Works, Inc. has interfaced
with several major roof tile manufacturers in the past and continues to work closely with
them as well as architects and roofing contractors in a constant ongoing Research and
Development program.
WIRE WORKS SYSTEMS
Both of the Wire works Systems, the
Twisted Wire Work system and the Hook and McLoop Fasteners System, are designed to keep in
check the elements of nature affecting a tile roof. They serve to significantly lengthen
the life span of the tile underlayment by drastically reducing the number of fastener
penetrations through the membrane (underlayment). Normal tile roofs that have been nailed
on have anywhere from 75 to over 300 nail penetrations through the membrane per roofing
square (100 square feet). Consider for a minute the Uniform Building Code Standard, Sec.
32 1206 (b)3 concerning the Water Absorption Test for roof tile which states,
"Condition of acceptance. No sample shall absorb more than 15
percent water of its dry weight." For one 10 lb. piece of tile (dry weight), that
could be an additional 1-1/2 lbs. of water, and keep in mind that a gallon of water weighs
about 8 lbs. This means that some moisture will inevitably pass through the majority of
roof tiles manufactured today. For this every reason many roof tile manufacturers
recommend the use of double roof jacks or double pipe vent flashings to help prevent roof
leaks. With the Wire Works Systems the number of penetrations may be less
than 30, depending upon the slope or pitch of the roof. Also these penetrations are sealed
shut with plastic roof cement or an equivalent which would be far too labor intensive and
costly to do for a 'nailed on' application. Obviously the intention here is to create a
condition where the life span of the underlayment is closer to that of the tile. Over the
long term these systems save material and labor costs by eliminating the need to
physically remove the tile, replace the underlayment, and reinstall the tile. Other
benefits of the Wire Works Systems are:
(1) Flexibility under adverse weather conditions and
building movement,
(2) Ease of tile replacement in the event of cracked or
broken tile, and
(3) The capability of installation over wood, steel, or
concrete roof decks, including those decks utilizing insulation as well.
Both of the Wire Works Systems are most commonly used with
clay roofing file. Each and every piece
of tile is mechanically fastened and therefore they comply with the Uniform Building Code
Standards as listed in Chapter 32. |
