Attending the meeting were: Jim Wheeler, Ron Chase, Dave
Herrnsteen, Thomas Rainey, , Cliff Ford, Betty Walters, Ray
Camardella. Mike Milligan arrived at 7:50 p.m.. Jon Kumin,
Clai Porter, Joel Bolger and James Wagner also attended the
meeting.
Mr. Chase moved the minutes of the meeting of September 18,
1991, be approved. Seconded by Mr. Herrnsteen, the motion
passed unanimously.
Mr. Camardella introduced Mr. Wagner, attorney for CTA
Architects; Mr. Bolger, Borough attorney; Mr. Kumin, Kumin
Associates; and Mr. Porter, NCP Construction, which is
involved in both construction and architectural work.
2. Main Elementary Roof Repair
Mr. Kumin began by detailing the history of the roof problem
and the investigation by Rick Button of Engineering
Evaluation and Investigation Services, Inc. (EEIS, Inc.)
_ Mr. Button estimated the cost of repair of the roof,
including the extensive dry rot problem in the plywood
sheathing, to be about $1,000,000.
Mr. Kumin and Mr. Porter also investigated the damage and
their findings include: the shingles on the roof appear to
be in excellent condition and water tight; the roof is
"soft" in spots due to the failing plywood deck immediately
below the shingles. There is extensive water staining in
the building. The vapor barrier appeared to have many gaps
in it. Taping was not evident.
Condensation appears to be the reason for the water damage
and dry rot. Testing was done for moisture, asbestos and
health hazards (from fungus growth). There is no asbestos
and no health hazard to either students or staff of the
building. In general the conclusions of the EEIS report
were confirmed, with one exception. It does not appear that
there is extensive damage to the 2x12s, as was indicated in
the earlier report.
Roof Repair Options were then discussed. All options are
based on removal of: existing shingles, felt, plywood, and
batt insulation. Option A also removes the existing vapor
barrier. The Options are given in most expensive to least
expensive cost ranking.
Q---
Option A would install a 10 mil polyethylene vapor barrier
over a new plywood structural deck, nailed to existing
2xl2s. Over the vapor barrier 2x8s would be installed and
the cavities would be filled with expanded or foamed -in -
place plastic insulation. Another plywood deck would be
installed above the 2x8s as a nailer for the new wood
shingles and the roof underlayment felt. There would be a
visual drawback to this option, the roof thickness would be
increased by 8 inches. Estimated cost is $1,014,000.
Option B would maintain and repair the existing vapor
barrier. Spray polyurethane foam insulation about 9 inches
deep installed between the existing 2xl2s. Above the 2xl2s
furred 2x4s laid flat and running up the slope of the roof
would provide ventilation and removal of moisture in the
remaining cavity of the 2xl2s. A premolded vinyl ridge vent
would be installed along all ridges. The plywood nailer for
the shingles would be attached to the top of the 2x4s.
Estimated cost is $922,000.
Option C would maintain and repair the existing vapor
barrier. A flash coat (about 211) of the foam insulation
mentioned in "B" would be applied to the vapor barrier. R-
30 batt insulation would then be installed between the
2xl2s. Vent space would be created by 2x4s, on edge,
running up the slope. This roof would have a continuous
ridge vent and eave venting. Estimated cost is $724,000.
Option D would maintain and repair the existing vapor
barrier and replace the existing wet batt insulation with
new batt insulation. A key difference between this option
and the existing roof is that a venting space will be
provided. Vertical 2x4s will be fastened on top of the
2xl2s to form the vent space as in the previous option.
Estimated cost is $734,000.
A recent lawsuit has caused the State Fire Marshal to
disapprove any roof that has not been UL approved. No
Alaska -type roof has that approval. The group was urged to
rank the options so that if the roof was not approved by the
Fire Marshal, another option could be immediately offered to
that office.
After discussion, Mr. Camardella said his ranking of the
Options, in order of preference, was: C, B, A, D. It was
pointed out that if the problem is dealt with now, the 2x12s
can be saved with minimal effort. Waiting can only add to
the deterioration and additional cost.
Mr. Milligan moved
that the Options
be ranked in order of
preference as C, B,
A, D. Seconded
by Mr. Rainey, the
motion carried.
Discussion was held on the type of material for the roofing.
Mr. Herrnsteen moved the same shingle as is on the roof now
(# 1 Perfection Blue Label, which is fire -retardant treated)
be placed on the roof. Mr. Chase seconded the motion, which
carried.
3. Board Comments
Mr. Rainey asked that the meetings of the Board be held on
Wednesday evenings. Other members agreed Wednesday was a
good choice.
4. Adjournment
There being no further business, the meeting was
adjourned at 10:00 p.m..
