RE: North Valley Business Center, Tukwila narrative for existing roof condition and reroof.
The existing roof is a 4 ply built -up (BUR) roof system. The existing roof has no insulation on top
of plywood roof decking.
Currently existing under the plywood decking is a 3 '/2" glass batt insulation.
The plywood deck is solid on all areas of existing roof.
The new roof system which will be installed over the existing roof is a TPO 60 mil white
membrane system manufactured by G.A.F.
The UL fire rating is a Class B.
The letter from G.A.F. states that this rating will not change with the new roof system.

of mechanically attached systems, and a minimum of 3"
for end laps. Membranes are provided with lap lines
87
along the side laps, the inside line is for mechanically
attached system overlaps (6" for TPO and 5" for PVC)
and the other line is for adhered and ballasted systems
overlap.
5. Install membrane so that the laps run across the roof
slope lapped toward drainage points. On metal decking,
install sheets perpendicular to deck direction so that
fasteners will penetrate the top flanges and not the flutes;
however, there will be limited areas of the roof (i.e.
perimeter areas) where this is not practical.
6. All exposed sheet comers shall be rounded a minimum
of 1 ".
7. Overlap roof membrane a minimum of 3" for end laps of
EveiGuard'° PVC and TPO membranes. End laps for
EverGuanF fleece -back membranes are made by butting
adjacent sheets and heat welding an 8" wide EverGuard®
PVC or EverGuanf TPO reinforced membrane flashing
strip over the joints.
B. Securement
1. Roof membrane shall be mechanically fastened in the
side lap area to the roof deck with fasteners and plates of
a type and spacing appropriate to the deck type and as
required by the Membrane Attachment Table.
2. The metal plates must be placed within 1/4" - 3/4" of
the membrane edge. Plates must not be placed closer
than 1/4" to the membrane edge.
3. Fasteners must be installed to achieve the proper
embedment depth. Install fasteners vertical to the deck,
without lean or tilt.
4. In the comer areas, additional fasteners will also be
installed through the perimeter half -width membrane
rolls to form a grid pattern, with an 8" wide reinforced
membrane flashing strip heat - welded over the additional
fasteners. "Comers" include both outside and inside
comers that measure 75° -105 °. Perimeter cap sheets may
overlap one another in the comer areas. Altematively, the
half sheet may be laid out in a "picture frame" manner,
burying the fasteners under the half sheets.
5. Mechanically attach membrane with screws and plates
to the roof deck at locations of deck angle changes in
excess of 5° (2" in 12 ").
6. Membrane may be heat welded to coated metal flanges.
Membrane must be secured to the roof deck within 6"
of the base of walls and curbs, at the perimeter, and all
penetrations with DRILL -TEC" Fasteners of a type and
spacing in accordance with in -lap attachment require-
ments, with a 12" on center maximum spacing.
Altematively, membrane may be extended vertically
3" up walls and curbs and secured to the wall /curb
substrate within 2" of the plane of the roof with
Mechanically Attached
Installation Specification
TPO & PVC
DRILL TEC" Fasteners and inverted Termination Bar of
type and spacing in accordance with in -lap attachment
requirements, with a 12" on center maximum spacing.
This alternative detail is required to be used for pressurized
buildings.
7. Install fasteners so that the plate is drawn down tightly
to the membrane surface. Properly installed fasteners
will not allow the plate/termination bar to move
(underdriving), but will not cause wrinkling of the
membrane (overdriving).
C. Field Seaming
1. Fabricate field seams using a current- generation
automatic hot air welding machine and a 10,000
watt voltage-controlled generator minimum. In addtion,
fabricate detail seams with automated hot air welders
where possible. Outdated welding equipment and
inadequate/fluctuating electrical power are the most com-
mon causes of poor seam welds.
2. Equipment Settings - The correct speed and temperature
settings for automatic welders are determined by
preparing test welds at various settings. The welds are
tested by application of pressure causing the seam to
peel apart. A satisfactory weld will fail by exposing the
scrim reinforcement called a "film tearing bond." A
deficient weld fails by separating between the two
layers of the membrane.
3. Adjustments to Equipment Settings- Many factors will
affect the settings: thicker membranes, lower air
temperatures, and overcast skies will generally require a
slower speed than would be required with thinner
membranes, higher air temperatures, and sunny skies.
The slower speed provides additional heat energy to com-
pensate for heat-draining concbtions. The test weld proce-
dure should be conducted at the beginning of every work
period (i.e., morning and afternoon) and following a sig-
nificant change in weather (i.e., air temperature, wind
speed, cloud cover.)
4. Membrane laps shall be heat - welded together. All welds
shall be continuous, without voids or partial welds.
Welds shall be free of bums and scorch marks.
5. Weld width shall be a minimum 1 -1/2" in width for
automatic machine welding. Weld width shall be a
minimum 2" in width for hand welding.
6. All cut edges of TPO and PVC reinforced membranes
must be sealed with EverGuard" TPO or PVC Cut Edge
Sealant.
D. Substrate Surface Preparation
1. Prepare substrate surfaces thoroughly prior to applica-
tion of new roofing materials. This is particularly
important for recover and reroofing applications.
2. Preparation includes, but is not limited to, removal of
existing flashings, replacement of wet/damaged existing
roofing materials, removal of loose aggregate, removal
of abandoned equipment, supports and penetrations,
replacement of damaged decking, etc.
3. Providing a smooth, even, sound, clean and dry substrate
minimizes the likelihood that underlying deficiencies
will cause premature deterioration or even failure of the
new roofing system.
E. Membrane Surface Preparation
1. Membrane must be clean of dirt and contaminants,
and free from dew, rain, and other sources of moisture.
Factory-fresh membrane typically will not require
cleaning prior to automatic welding, provided that
welding is performed immediately after placement and
securement of the membrane.
2. Membrane that has been exposed for over 12 hours or
has become contaminated will require additional
cleaning methods.
3. Light Contamination - Membrane that has been exposed
ovemight up to a few days to air -bome debris, foot
traffic, or dew or light precipitation can usually be
cleaned with a white cloth moistened with EverGuards
TPO use or acetone for PVC. Be sure to wait
for solvent to flash off prior to welding.
4. Dirt-Based Contamination - Membrane that is dirt-
encrusted will require the use of a low - residue cleaner such
as Formula 409 and a mildly abrasive scrubbing pad to
remove the drt. This must be followed by cleaning with
a white cloth moistened with EveGuarcP TPO Cleaner
or acetone for PVC. Be sure to wait for
solvent to flash off prior to welding.
5. Exposure -Based Contamination - Membrane that is
weatheredd/oxidzed will require the use of EverGuanf
TPO Cleaner or acetone for PVC and a mildly abrasive
scrubbing pad to remove the weathered/oxidized top
surface layer. This must be followed by cleaning with a
white cloth moistened with EverGuanF TPO Cleaner or
acetone for PVC. Unexposed membrane left in inventory
for a year or more may need to be cleaned as instmcted
above. Be sure to wait for solvent to flash off prior to
welding.
6. Chemical -Based Contamination - Membrane that is
contaminated with bonding adhesive, asphalt, flashing
cement, grease and oil, and most other contaminants
usually cannot be cleaned sufficiently to allow an
adequate heat weld to the membrane surface. The
membrane should be removed and replaced in these
situations.

O. Heater Stacks
1. Field - fabricated two -piece membrane flashings of
EverGuard' umeinforced flashing are typically installed
at heater stacks. EverGuard® TPO and PVC have coned
type prefabricated pipe flashing that may work in this
instance. If not then field fabricated
membrane flashings of EverGuani' TPO UN -55 or
EverGuard° PVC UN-80 may be used The temperature
of any heater stack that comes into contact with the
Eve/Guard' membrane should not exceed 160°F.
2. Heat stacks must be equipped with either cone- shaped or
vertical tube -type flashing sleeves so that the membrane
flashing is not directly in contact with the heater stack.
3. Mechanically attach the roof membrane to the structural
deck with DRILL -TEC'" screws and plates around the
penetration base prior to flashing installation.
4. All stack flashings must be secured at their top edge
by a stainless steel clamping band over Water Block
and sealed with EverGuarcr Caulking.
5. Field- fabricated membrane flashings may be adhered to
the flashing sleeve with EverGuardr TPO or EverGuard?
PVC Bonding Adhesive.
P. Drain Inserts - PVC Only
1. EverGuard° PVC roofing membrane is typically
terminated at PVC drain inserts by heat welding the
membrane to the PVC coated drain flange (if available),
or by securing the membrane between the drain flange
and the clamping ring.
2. Drain inserts shall only be used in the event the original
drain is damaged and cannot be repaired without complete
replacement of the drain.
3. All drains shall be provided with a drain sump of a 36"
x 36" minimum dimension, if possible. Fasteners shall
be installed 12" on center or a minimum of 4 per pene-
tration.
4. The drain insert is installed on top of the roofing
membrane and is secured to the roof deck 6" o.c. with
DRILL-TEC" screws.
5. A separate reinforced membrane drain flashing sheet is
heat welded to the roofing membrane. The drain flashing
sheet is heat welded to a compatible drain flange.
6. Install the drain damping ring if applicable.
7. All drains shall be provided with a strainer basket.
Q. Wood Support Blocking
1. Wood support blocking, typically 4" x 4 ", is usually
installed under light -duty or temporary roof - mounted
equipment, such as electrical conduit, gas lines,
condensation and drain lines.
93
2. Install wood support blocking over a protective layer of
EverQuan F PVC or TPO membrane or EverGuard°
Walkway Pad. Place wood blocking on oversized slip
sheet, fold two sides vertically, and fasten with roofing
nails into the blocking.
R. Satellite Dish Support Bases
1. Install satellite dish support bases over a protective layer
of EverGuard° Walkway Pad
S. Lightning Suppression Clips
1. Secure lightning suppression clips to the roof surface by
means of 2" wide EveiGuan F PVC or EverGuarcP TPO
Flashing membrane strips heat welded to the roof
membrane.
3.13 Traffic Protection
A. Walkway rolls must be installed at all roof access locations
including ladders, hatchways, stairs and doors. Install
walkway rolls at other thsignated locations including
roof-mounted equipment work locations and areas of repeat-
ed rooftop traffic.
B. Walkway rolls must be spaced 6" to allow for drainage.
C. Heat weld walkway rolls to the roof membrane surface con-
tinuously around the walkway pad perimeter.
D. TPO walkway rolls may also be installed with TPO primer
and 3" seam tape. First, mll or brush the TPO primer on
the back of the TPO pad along the edges and down the mid-
dle of length of the pad. Clean and prime the roof mem-
brane where the pad will be installed Install tape to the
back of the pad where cleaned (edges and middle) and roll in
with a silicone hand roller. Remove the release paper and
install the taped pads directly onto the roof membrane.
Secure the pads by rolling into place.
3.14 Temporary Closures
A. The roofing installation must be made watertight at the end
of each day's activity to prevent water infiltration into the
completed roofing system installation.
B. Complete all flashings and terminations as the roofing
installation progresses.
C. At the edge of the completed roofing system installation,
extend the roofing membrane a minimum of 6" beyond the
edge. Seal the roofing membrane to the surrounding deck or
substrate surface with hot asphalt or foam sealant.
D. Remove all temporary night seal materials prior to continuing
with the roof installation and dispose of properly.
3.15 Field Quality Control
A. Inspect completed roof sections on a daily basis. It is the
contractor's responsibility to probe all heat - welded seams
and perform an adequate number of seam cuts to ascertain
seam consistency.
Mechanical) Attached
Installation Specification
TPO & PVC
B. Immediately correct all defers, irregularities, and
deficiencies identified during inspections. All voids that are
found must be patched over per specifications. Do NOT
reweld seam voids more than 24 hours after initial welding
of the seam.
C. Remedial wort( shall be performed with like materials and in
a manna- consistent with the balance of the roofing installa-
tion so as to minimize the number of repair patches.
D. Excessive patchwork will mire replacement of the entire
affected membrane section from lap to lap.
3.16 Cleaning
A. Remove bonding adhesive, bituminous markings and other
contaminants from finished surfaces. In areas where
finished surfaces are soiled by asphalt or any other source of
soiling caused by work of this or other sections, consult
manufacturer of surfaces for cleaning advice and conform to
those instructions.
B. Cut out and remove any sheet membrane contaminated with
solvent -based adhesive, bituminous markings, and other con-
taminants from finished surface. Repair sheet damage by first
cleaning the area with an all- purpose cleaner, then rinse off
soapy residue. Reactivate membrane using the appropriate
EverGuard' cleaner, wiping with a damp (not saturated) rag.
Complete repair by installing a patch of like material to spe-
cific system requirements.
3.17 Maintenance
A. Upon completion of the roofing system, the owner should
establish a semi-yearly inspection and maintenance
program in acconbnce with standard good roofing practice
guarantee requirements.
B. Repair cuts, punctures and other membrane damage by dean-
ing membrane (see section 3.11.E), followed by heat welding
a membrane repair patch of sufficient size to extend a mini-
mum of 2" beyond the damaged area. If heat welding to the
top surface of the existing membrane is ineffective, the patch
must be heat welded to the underside of the existing sheet
after proper preparation.
C. Any damage to adhered membrane areas or at locations of
mechanical attachment shall be repaired so that the repaired
area remains fully adhered or mechanically attached
