12/7/2010 07550 - Page 4 Section 07550
Modified Bitumen-Hot Applied
site. If any material or equipment is stored on the roof, the contractor must make sure that the
integrity of the deck is not compromised at any time. Damage to the deck caused by the
contractor will be the sole responsibility of the contractor and will be repaired or replaced at
his expense.
19 MANUFACTURER'S INSPECTIONS
A. When the project is in progress, the Roofing System Manufacturer will provide the
following:
1. Keep the Architect informed as to the progress and quality of the work as
observed.
2. Provide job site inspections a minimum of three days a week.
3. Report to the Architect in writing any failure or refusal of the Contractar to
correct unacceptable practices called to the Contractor's attention.
4. Confirm after completion of the project and based on manufacturer's
observation and tests that manufacturer has observed no applications procedures
in conflict with the specifications other than those that may have been
previously reported and corrected.
1.10 PROJECT CONDITIONS
A. Weather Condition Limitations: Do not apply roofing membrane during inclement
weather or when a 40% chance of precipitation is expected.
B. Do not apply roofng insulation or membrane to damp deck surface.
C. Do not expose materials vulnerable to water or sun damage in quantities greater than can
be weatherproofed during same day.
D. Proceed with roofing work only when existing and forecasted weather conditions will
permit unit of work to be installed in accordance with manufacturer's recommendations
and warranty requirements.
E. All slopes of greater than 1-1/2:12 do require back-nailing to prevent slippage of the ply
sheets. Ring or spiral shank 1" cap nails, or screws and plates should be utilized at a rate
of one fastener per ply (including the modified) at each insulation stop. Insulation stops
should be placed 16' o.c. for slopes less than 3:12 and 4' o.c. for slopes greater than 3:12.
On non-insulated systems, nail each ply directly into the deck at the rate specified above.
When slope exceeds 1:12, strapping the plies is recommended to help prevent slippage.
Four additional fasteners should be installed at the upper edge of modified bitumen sheet
when strapping the plies.
1.11 SEQUENCING AND SCHEDULING
A. Sequence installation of modified bituminous sheet roofing with related units of work
specified in other sections to ensure that roof assemblies including roof accessories, flashing,
trim and joint sealers are protected against damage from effects of weather, corrosion and
adjacent construction activity.
B. All work must be fully completed on each day. Phased construction will not be accepted.

PART 3 - EXECUTION
3.1 EXAMINATION
A. Examine substrate surfaces to receive modified bitumen sheet roofing system and
associated work and conditions under which roofing will be installed. Do not proceed
with roofing until unsatisfactory conditions have been corrected in a manner acceptable
to Roof System Manufacturer.
3.2 GENERAL INSTALLATION REQUIREMENTS
A. Cooperate with manufacturer, inspection and test agencies engaged or required to
perform services in connection with installing the roof system.
B. Insurance/Code Compliance: Where required, install and test the roofing system to
comply with governing regulation and specified insurance requirements.
12/7/2010 07550 - Page 8 Section 07550
Modified Bitumen-Hot Applied
C. Protect other work from spillage of roofing materials and prevent materials from entering
ar clogging drains and conductors. Replace or restore other work damaged by
installation of the modified bituminous roofing system work.
D. Coordinate installing roofing system components so that insulation and roofing plies are
not exposed to precipitation or left exposed overnight. Provide cut-offs at end of each
day's work to cover exposed ply sheets and insulation with two (2) plies of # 15 organic
roofing felt set in full moppings of bitumen and with joints and edges sealed with roofng
cement. Remove cut-offs immediately before resuming work.
E. Asphalt Bitumen Heating: Heat and apply bitumen according to EVT Method as
recommended by NRCA. Do not raise temperature above minimum normal fluid-holding
temperature necessary to attain EVT (plus 5°F at point of application) more than 1 hour
prior to time of application. Determine flash point, finished blowing temperature, EVT,
and fire-safe handling temperature of bitumen either by information from manufacturer
or by suitable test. Do not exceed recommended temperature limits during bitumen
heating. Do not heat to a temperature higher than 25° below flash point. Discard
bitumen that has been held at temperature exceeding finishing blowing temperature
(FBT) for more than 3 hours. Keep kettle lid closed except when adding bitumen.
F. Bitumen Mopping Weights: For interply mopping, apply bitumen at the rate of
approximately 25 ]b. of bitumen per roof square. For a flood coat, apply bitumen at the
rate of approximately 60-70 lb. of bitumen per square (plus or minus 25 percent on a total
job average basis).
G. Substrate Joint Penetrations: Prevent bitumen from penetrating substrate joints, entering
building, or damaging roofing system components or adjacent building construction.
H. Apply roofing materials as specified herein unless recommended otherwise by
manufacturer's instructions. Keep roofing materials dry before and during application.
Do not permit phased construction. Complete application of roofing plies, modified sheet
and flashing in a continuous operation. Begin and apply only as much roofing in one day
as can be completed that same day.
L Cut-Offs: At end of each day's roofing installation, protect exposed edge of incomplete
work, including ply sheets and insulation. Provide temporary covering of two (2) plies of
#15 organic roofing felt set in full moppings of bitumen with joints and edges sealed.
33 BASE SHEET INSTALLATION

Re: Vail Public Library
Roof Snow Loads
Dear Mr. Kawulok,
REI Structural has been asked to review the existing roof live load capacity after the completion of
the reroofmg of the Vail Public Library.
The Vail Public Library was originally designed with a soil roof 17 to 18 inches thick and a roof live
load of 75 pounds per square foot (ps fl. An 18" thick soil roof will weigh approximately 165 psf.
The total design load was therefore 240 psf.
The reroofing project only replaced 11 to 12 inches of soil on the roof which will weigh
approximately 110 ps£ Taking into account load factors required by the building code which vary for
load condition, the new snow load capacity of the roof is 110 psf.
The Town of Vail currently requires flat roofs to be designed for 100 psf. Therefore, due to the
reduction in soil on the roof, the roof of the Vail Public Library now exceeds the current snow load
requirements.
Please feel free to contact me if you have any questions.
Sincerely,
",oQ-PO BRR O 1'�`
