RE: Reroof at 6275 South 143rd Avenue
Tukwila, WA
Jay:
I have reviewed the loads with consideration of the addition of approximately 0.4 psf for
the new roofing. The added roofing may be applied without modifying the existing
building.
The added load increases the gravity loads by 1.1% over the original design. Per IBC
3404.3 we may increase the loads a maximum of 5% without reinforcing the members.
If you have any questions please call.
Sincerely,

RE: Air Flow Building, 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 craft foil.
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.

Jay:
I have reviewed the Toads with consideration of the addition of approximately 0.4 psf for
the new roofing. The added roofing may be applied without modifying the existing
building.
The building was previously reroofed. The second layer (2.0 psf) will be removed,
leaving the original. The added load increases the gravity loads by 1.1% over the
original design. Per IBC 3404.3 we may increase the loads a maximum of 5% without
reinforcing the members.
If you have any questions please call.

NORTHWEST, INC., P.S.

3.11 Membrane Installation
A. Placement
1. Place roof membrane so that wrinkles and buckles are
not formed. Remove any wrinkles or buckles removed
from the sheet prior to permanent secutement. Roof
membrane shall be mechanically fastened after it is rolled
out, followed by welding to adjacent sheets.
2. Full -width rolls shall be installed in the field of the roof.
3. Half -width rolls shall be installed in the perimeter region
of the roof. Width of the roof perimeter region shall be
determined in accordance with the Perimeter Half Sheet
Table.
4. Overlap roof membrane a minimum of 6" for side laps
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 (Erection 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
EverGuaitF fleece -back membranes are made by butting
adjacent sheets and heat welding an 8" wide EverGuardF
PVC or EverGuarddf TPO reinforced membrane flashing
strip over the joints.
13. 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, a11itional fasteners will also be
installed through the perimeter half -width membrane
rolls to form a grid pattem, with an 8" wide reinforced
membrane flashing strip heat -welded over the additional
fasteners. "Comets" include both outside and inside
corners that measure 75°-105°. Perimeter cap sheets may
overlap one another in the comer areas. Alternatively, 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
(underd iving), 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 addition,
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
ctficient 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 conditions. The test weld proce-
dure should be conducted at the beginning of every work
period (i.e., moming 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 welting.
6. All cut edges of TPO and PVC reinforced membranes
must be sealed with EveGuartr 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 addtional
cleaning methods.
3. Light Contamination - Membrane that has been exposed
ovemight up to a few days to air -borne debris, foot
traffic, or dew or light precipitation can usually be
cleaned with a white cloth moistened with EverGuanf
TPO use or acetone for PVC. Be sure to wait
for solvent to flash off prior to welting.
4. Dirt -Based Contamination - Membrane that is tirt-
encusted will rewire the use of a low -residue cleaner such
as Formula 409 and a mildly abrasive scrubbing pad to
remove the tint. This must be followed by cleaning with
a white cloth moistened with EverGuard° 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
weathered/oxidized will require the use of EveGuacr
TPO Cleaner or acetone for PVC and a mildly abrasive
scrubbing pad to remove the weathered/oxicfized 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 instructed
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.

Dear Permit Holder:
In reviewing our current records, the above noted permit has not received a final inspection by the City of Tukwila Building
Division. Per the International Building Code, International Mechanical Code, Uniform Plumbing Code and/or the National
Electric Code, every permit issued by the Building Division under the provisions of these codes shall expire by limitation and
become null and void if the building or work authorized by such permit has not begun within 180 days from the issuance date
of such permit, or if the building or work authorized by such permit is suspended or abandoned at any time after the work has
begun for a period of 180 days. Your permit will expire on 10/19/2013.
Based on the above, you are hereby advised to:
1) Call the City of Tukwila Inspection Request Line at 206-431-2451 to schedule for the next or final inspection.
Each inspection creates a new 180 day period, provided the inspection shows progress.
-or-
2) Submit a written request for permit extension to the Permit Center at least seven (7) days before it is due to
expire. Address your extension request to the Building Official and state your reason(s) for the need to extend
your permit.
The Building Code does allow the Building Official to approve one extension of up to 180 days. If it is determined that your
extension request is granted, you will be notified by mail.
In the event you do not call for an inspection and/or receive an extension prior to 10/19/2013, your permit will become null
and void and any further work on the project will require a new permit and associated fees.
Thank you for your cooperation in this matter.
Sincerely,
Bill Rambo
Permit Technician

Jay:
I have reviewed the loads with consideration of the addition of approximately 0.4 psf for
the new roofing. The added roofing may be applied without modifying the existing
building.
The added load increases the gravity loads by 1.1% over the original design. Per IBC
3404.3 we may increase the loads a maximum of 5% without reinforcing the members.
If you have any questions please call.

Building Division Review Memo
Date: March 5, 2013
Project Name: Air Flow Building
Permit #: D13-066
Plan Review: Allen Johannessen, Plans Examiner
The Building Division conducted a plan review on the subject permit application. Please address the following
comments in an itemized format with revised plans, specifications and/or other applicable documentation.
(GENERAL NOTE)
PLAN SUBMITTALS: (Min. size 11x17 to maximum size of 24x36; all sheets shall be the same size. New
revised plan sheets shall be the same size sheets as those previously submitted.)
(If applicable) Structural Drawings and structural calculations sheets by a registered engineer shall have a current
signed stamp -seal. Architectural design sheets and documents by a registered architect shall also have a current
signed stamp -seal.
1. The scope of work indicates only removing one layer of roofing. Building code requires "New roof coverings
shall not be installed without first removing all existing layers of roof coverings down to the roof deck where
any of the following conditions occur: item #3. Where the existing roof has two or more applications of any
type of roof covering." Revise the scope of work for this reroof project to specify removing all roofing down to
the deck. (2009 IBC 1510.3 #3.)
2. Washington State Energy code requires alterations or repairs shall comply with nominal R -values requirements
in Table 13-1 where the existing roof deck is exposed and the roof membrane is being replaced. The memo by
Jay Mylar indicates craft foils exist under the roof deck; however it does not specify what that is or what the R -
value is. Insulation entirely above deck shall be R-30 c.i. (continuous insulation) per Table 13-1 for
nonresidential buildings. Depending on what the R value is under the deck, the R value of the insulation below
deck may be included in the calculation for total R-30. Revise scope of work to show insulation shall meet
Washington State energy code requirements. Provide the necessary specifications for insulation above and
below deck as it applies. (2009 WSEC Section 1130, 1132, 1132.1 & Table 13-1)
Should there be questions concerning the above requirements, contact the Building Division at 206-431-3670.
No further comments at this time.
