OBSERVATIONS OF THE EXISTING ROOF CONDITION:
Area #1
Turner Morris was called to investigate a leak below the dumpster staging area at the Vail Valley
Medical Center. We were dispatched multiple times for a “reoccurring” leak. Each time we were
dispatched we removed more snow and expanded our search area. During our third trip a very
large area was removed of snow and over 20 holes were patched. Although we feel that we
found most of the holes there is still a very good chance that other holes will leak. Additionally
there was a significant amount of water in the roof system, if not dried out the moisture may
cause other roof failures later in the roofs life.

Area #2
Turner Morris was called to investigate we found multiple issues with the expansion joint and
holes found in the membrane. Although we feel that we found most of the holes there is still a
very good chance that other holes will leak. Additionally there was a significant amount of water
in the roof system, if not dried out the moisture may cause other roof failures later in the roofs
life.

Area #3
Turner Morris was called to investigate a leak above the ambulance garage at Vail Valley
Medical Center. We were dispatched multiple times for a “reoccurring” leak. Each time we were
dispatched we removed more snow and expanded our search area. It was determined that during
the roof installation poor roofing practices were used and the roof is failing around the entire
perimeter of the roof. Because the roof doesn’t adhere to the manufacturer’s specifications we
recommended a full replacement in this area.

PROJECT:
Vail Medical Center Roof Replacement 2018
181 West Meadow Drive
Vail, CO 81657
SCOPE OF WORK: Membrane Overlay
Area #1-4:
a. Coordinate with Royal Adhesive representative to complete a pull test of existing EPDM to wood fiberboard to confirm that
utilization of low-rise foam can be completed for installation of the new roof system reusing existing insulation.
2. Complete moisture testing of existing perlite insulation below wood fiberboard and replace saturated perlite and wood fiberboard
insulation on a time and material basis. This will be completed using a 4” flatstock polyisocyanurate to match height of existing
minimum insulation thickness with additional flatstock and tapered polyisocyanurate insulation on top at a cost of $4-$6/sf based on
thickness of insulation.
3. Adhere ½ high density Polyisocyanurate substrate board to existing EPDM using a low-rise foam adhesive that is LVOC and useable
in low temperatures.
4. Adhere new 60 mil EPDM using LVOC glues that are compatible in temperatures 20 degrees and above. Note that although glues are
LVOC they will still emit an odor.
5. Extend EPDM base flashing up walls and rooftop curbs to match height of existing base flashings.
6. Temporarily remove existing cap metal along parapet walls and save for reinstallation. Extend EPDM up and over parapet walls and
reinstall existing cap metal. Note that cap metal may appear slightly dented after removal/reinstallation. An option for cap metal
replacement can be provided upon request.
7. Tie into existing drains, walls, curbs, roof penetrations per manufacturer’s specifications.
Area #1-4 - Warranty:
1. Provide owner with manufacturer’s 10-year labor and material watertight warranty for Area #1 –
