A. Deck Preparation
1. Provide smooth, clean, dry deck, free of debris, and sufficiently
rigid to support the roofers and their mechanical equipment without
deflection that will strain or rupture any of the built -up roofing
components.
2. Make any significant depressions, holes, deformations and similar
faults, smooth prior to new roofing application.
3. Clean all surfaces of debris and of any moisture before
proceeding with application of roofing material.
4. Refer to Manufacturer's General Requirements for other
appropriate substrate requirements.
B. Deck Inspection
1. Contractor is responsible for insuring that the roof surface is
clean, firm, smooth, dry, properly secured against movement, and
acceptable to the Manufacturer and to himself, prior to application
of roofing materials.
2. Commencement of roof application over any section denotes
acceptability by Contractor of any section's readiness to receive
built -up roofing and he will be responsible for any corrective work
which may be occasioned by his having started over an
unsatisfactory surface.
07510.32 GENERAL APPLICATION REQUIREMENTS:
A. Do not apply roofing unless correct asphalt application
temperatures can be maintained to obtain good embeddment and adhesion.
Do not conduct operations when water in any form is present on deck,
such as rain, dew, ice, frost, or snow. Limit water to containers for
human consumption.
B. Take precautions to keep materials clean, dry and free of damage.
C. Do not start application of more base sheet each day than can be
covered within the some day.
D. At the end of the day, edge -seal the finished portion of the roofing
system completed that day with fabric or felt set into hot bitumen or
plastic cement. Remove edge seals prior to the start of the next
day's work.
E. Start roofing work in dry weather only and without threat of immediate
inclement weather. Keep the roofed area of the building watertight
each day as the work progresses.
F. Use only materials and procedures that are proper and suitable for the
slopes and for the underlying materials to which they are attached.
G. To avoid displacement of asphalt and interply voids, ensure that no
heavy objects are placed on the membrane. Use all means necessary to
protect the membrane before, during, and after installation. In the
event of damage or asphalt displacement, immediately make all repairs
and /or replacements necessary to the satisfaction of the Owner at no
additional cost. Work all felts from the up slope side. Do not walk
on /over felts freshly laid in hot bitumen. ft
H. Provide approved and operable fire extinguishers on hand at all
times on the roof and near the kettle or tanker. During all hot
application work, including kettle loading, have all roofers wear
protective clothing (i.e. long- sleeved shirts, gloves face shield for
kettle operator). During any torch work, provide an additional fire
extinguisher for each torch. Follow all additional requirements of
OSHA Safety Regulations.
1. All torch work shall stop 1 1/2 hours prior to crews leaving the site
The roof contractor shall inspect all torch details, each day after all
work on the roof has ceased.
I. Run interpiy mappings of hot asphalt (at the E.V.T.) continuously
and apply at the specified rate. Use application methods which ensure
that all plies are completely embedded in asphalt. Broom in all plies
immediately after being laid.
J. Cover all attached base sheet with the completed roof membrane
system (except surfacing) at the end of each days work. Make all roof
terminations and openings waterproof at the end of each day's work.
K. Phasing of roof membrane application or temporary membrane is not
acceptable. Install membrane, excluding surfacing, in final form on a
day -to -day basis.
L Install proper width starter sheets to insure minimum specified
coverage throughout. Stagger starter sheets as needed to offset joints
between base, ply and surfacing sheets.
M. Do not use any wet or damaged materials.
N. Bitumen Heating Euipment must be thermostatically controlled.
Equipment must be clean and in sufficiently good condition to perform
specified work.
0. Felt Layer (if used): Multiple gate valve type that spreads hot
asphalt on the roof surface just ahead of the felt as it is applied.
Use clean equipment in good condition.
P. Rotary- Drum -Type Felt Layer: Do not use for application of roofing
products.
Q. Asphalt
1. Apply asphalt per EVT at the point of application. Discontinue
operations if asphalt temperatures at point of application cannot
be maintained at the EVT.
2. Equip asphalt heating equipment with an accurate thermostat and
thermometer.
3. Do not overheat asphalt. Kettle temperatures generally may not
exceed 500'17.
4. Do not heat asphalt to the minimum flash point. The minimum
finished blowing temperature may not be exceeded for more than a
total of four hours, for any asphalt batch or portion thereof.
Remove from the project any asphalt heated above these limits.
5. Reduce tanker temperatures to 325'F - 350'F overnight or during
discontinued work periods.
6. Cold weather application requires the use of insulated supply lines
and equipment to minimize temperature drop from the kettle or
tanker to the point of application.
7. Do not apply materials when foaming, blistering, or bubbling
of the hot bitumen occurs. Remove any materials applied when such
activity occurs.
R. Primer
1. Material may be applied by brush, spray, or roller.
2. Materials may not be diluted or adulterated.
3. Apply primer to any metal surfaces to receive bituminous
products at the nominal rate of one gallon per 100 square feet.
Allow to dry thoroughly prior to application of roofing materials.
