INTRODUCTION

Roof Design & Consulting Services, Inc., an independent architectural and roof consulting firm, has been retained to evaluate the existing roof systems installed on the subject property and to evaluate the condition of the interior and exterior finishes. At the time of our site visit, active leaks were reported. There was evidence of repeated water infiltration, and interior finish damages were noted.

INSPECTION

The site visit and inspection were conducted on April 19, 2018, by Mr. Josh Hankins, RRO, CMI and Mr. Jim Ferri, RRO. The weather was clear and the temperature was 65°F. Certain photographs were taken to illustrate existing conditions, and limited physical investigations were performed to verify existing conditions. No destructive or invasive examinations were made. The inspection was conducted using accepted Industry Standards and the following rules and guidelines:

• NRCA Roofing and Waterproofing Manual – National Roofing Contractors Association (NRCA)

• Property Loss Prevention Data Sheets for Roofing Contractors – Factory Mutual (FM) • International Building Code (IBC) • SMACNA Sheet Metal Manual – Sheet Metal & Air Conditioning Contractor’s National

Association (SMACNA) • Unified Facilities Criteria (UFC) – Department of Defense • Wind Design Standards for Edge Systems Used with Low Slope Roofing Systems -

Single Ply Roofing Industry (SPRI) • ANSI/SPRI/FM 4435/ES-1

RDCS was given access and was accompanied by SFC Steve Bonds.




Roof Inspection & Building Evaluation – ARMY NATIONAL GUARD READINESS CENTER - Memphis, TN – Page 2

BACKGROUND& DESCRIPTION

The Memphis Readiness Center is a one-story structure constructed in 1982. The building was designed by Haglund and Venable, Architects of Memphis, TN. Roof repairs were performed in 1988, and the building was reroofed in 2010. The roofing contractor was Accurate Roofing Co. Inc. of Potts Camp, MS.

The building construction consists of load bearing masonry walls with exterior brick veneer, shallow spread concrete footings, and concrete slab on grade. The windows are operable and fixed aluminum units.

Over the classroom and administration areas, the building roof structure consists of steel joists and steel roof deck. Above the firing range and drill hall is a tongue and groove cementitious wood fiber board on steel trusses and purlins. A Soprema modified bitumen roof system is installed over the entire facility. A manufacturer’s roof system warranty is in effect until April 2030. Drainage on the all areas is provided by gutters and downspouts which spill to grade.

EXHIBITS

PREFACE TO EXHIBITS: The exhibits presented herein are intended to illustrate both general and specific conditions observed during the roof investigation. All deficiencies on each roof area have not been shown, and their omission does not imply that those conditions may not be present. These photographs seek to convey the overall assessment of the roofs and to emphasize particularly significant conditions.

Exhibit No. 1

The Memphis Readiness Center is a one-story structure situated on a level open site in Shelby County, TN. The building is entirely unprotected by vegetation or terrain.


Exhibit No. 2

Above the classroom and administrative areas, the existing roof is a modified bitumen roof system installed with hot asphalt over rigid insulation, over a steel roof deck.

Exhibit No. 3

The membrane is in good condition with minimal granule loss or physical damage present.


Exhibit No. 4

We did not do destructive testing or core cuts to verify the installation, but it appears that the underlying sheet has been run parallel (up and down) to the slope. If this is a base sheet, it does not comply with manufacturer’s requirements or industry standards. If this is a recover, and the vertical plies are the previous cap sheet, then the installation of the cap sheet appears satisfactory.

Exhibit No. 5

Blisters are forming between the cap sheet and underlying layers. Several blisters intersect seams and are beginning to pull apart. Typically, blisters indicate the presence of moisture under the sheet or delamination caused by poor adhesion.


Exhibit No. 6

At the front entrance, a large blister has formed beneath the cap sheet and has filled with water. Because of continuous exposure to moisture, the water will infiltrate into the building.

Exhibit No. 7

This gas flue was not secured and openings were found around the umbrella and outer sleeve.


Exhibit No. 8

A pipe boot intended for use on a metal roof was used on this penetration. This is not an acceptable detail.

Exhibit No. 9

Pre-fabricated pitch pockets (commonly referred to as lockin’ pockets) were used on several pipe penetrations.


Exhibit No. 10

Because of their shallow depth, and the use of a single part filler, several of the pitch pockets were no longer watertight. A leak was reported in the computer lab directly beneath this penetration.

Exhibit No. 11

A large opening in the filler is present adjacent to the refrigerant lines.


Exhibit No. 12

On all roof areas, a raised gravel stop was used instead of a low-profile drip edge. This results in standing water around the perimeter of the roof system and has caused several soft spots in the insulation.

Exhibit No. 13

Evidence of long term standing water is readily visible. Also, note the blister along the membrane edge seam.


Exhibit No. 14

Not only was the wrong edge metal profile used, the workmanship was very poor. Note the opening into the roof system behind the fascia.

Exhibit No. 15

Directly beneath this location evidence of water penetration behind the gutter is evident. We were not able to determine if the wood nailers around the perimeter of the roof were properly protected or have been damaged by the continuous exposure to moisture.


Exhibit No. 16

The roof system on the drill hall and firing range consists of modified bitumen roof membranes over rigid insulation over tongue and groove cementitious wood fiber roof deck over steel trusses and beams. Note the lines of the underlying plies of the roof system running perpendicular to the cap sheet.

Exhibit No. 17

The cap sheet was run parallel to the slope of the high roof. The manufacturer does not recommend installation using hot asphalt on slopes over ½:12. This roof was measured at 9° which is 2:12


Exhibit No. 18

The cap sheets are beginning to slide down the slope and are separating at the end laps.

Exhibit No. 19 The seam at the ridge of the drill hall is likewise slipping. The sheets are separating and will eventually cause leaks. All end laps are required to be staggered which was not done along the ridge.


Exhibit No. 20

Several locations were found where nails have backed out of the edge metal and the flashing strip is not properly bonded. Again, note the use of a raised edge gravel stop instead of a drip edge.

Exhibit No. 21

The same raised edge gravel stop was used on the rake edges of the high roof and stripped in with foil faced flashing.


Exhibit No. 22

The foil facing has failed in multiple locations, exposing the asphalt beneath. Asphalt used in sheet materials is not a UV stable product and depends on granules or foil facing to prevent UV degradation. This condition will continue to worsen and expose more asphalt.

Exhibit No. 23

The louvers on the ventilation fans for the drill hall are loose or missing. This offers no protection against wind-blown rain which easily can penetrate into the building or into the wall system.


Exhibit No. 24

Several of the detached louver blades were found on the roof surface. These are constructed of lightweight aluminum and could easily become wind-borne causing damage to the roof surface, vehicles surrounding the building, or pedestrians outside the readiness center.

Exhibit No. 25 An expansion joint is installed around the perimeter of the drill hall. It is a prefabricated Johns Manville “Expand-O-Flash” and has field fabricated transitions. Multiple applications of mastic are evident on the EPDM bellows. This is not considered a permanent repair nor does it meet manufacturer’s requirements or industry standards. Also, note the concrete splash block installed directly on the roof surface with no sacrificial slip sheet to protect the roof membrane.


Exhibit No. 26

Overall, the exterior masonry of the Memphis Readiness Center was in good condition. Very minimal damage was noted to the building exterior. Less than 20 LF of masonry joints and 6 bricks were noted to require repair or replacement.

Exhibit No. 27 The exterior masonry control joints are in poor condition. The sealant is dry, brittle, and cracked and can allow moisture to enter the exterior wall.


Exhibit No. 28

At multiple locations around the facility, evidence of moisture penetration behind or from the gutters was noted.

Exhibit No. 29

The downspouts spill to grade around the facility and at many locations have caused erosion around the splash blocks due to poor drainage. No underground drainage system is provided.


Exhibit No. 30

One window was found with the seals failed. The haziness is a result of moisture infiltration between the panes of glass.

Exhibit No. 31

At the front entrance, several areas of spalling concrete were observed.


Exhibit No. 32

Upon closer inspection, the pins securing the concrete panels to the lintels have corroded. When metals corrode, the iron oxide increases their overall size. This can push mortar out of joints and crack pre-cast concrete panels. This phenomenon is known as “rust jacking.”

Exhibit No. 33

No condensate drain has been installed on this window AC unit and the condensate is running down the outside face of the wall. The continuous exposure to moisture will degrade the masonry and the grout between the bricks.


Exhibit No. 34

Similarly, the continuous exposure to moisture at the hose bib in the can wash will cause the same damage. Evidence of leaking over an extended period is obvious.

Exhibit No. 35

The louver over the ventilation fan on the firing range is inoperable and stuck in the open position. This will allow wind-blown rain into the building and into the wall assembly.


Exhibit No. 36

The interior masonry walls were in fair to poor condition overall with cracks observed in multiple locations. Approximately 450 LF of damaged masonry joints and 20 damaged masonry units were identified.

Exhibit No. 37

Approximately 200 SF of deteriorated metal roof deck was found. Some areas were found to have rusted entirely through the deck as shown here.


Exhibit No. 38

The structural supports for a previously installed solar collector system are still present after the reroofing in 2010. These are direct openings through the roof deck into the roof system. Warm, moist, unconditioned air can penetrate into the roof system at these locations. Also, notice the “expansion joint” running from left to right in the roof deck.

Exhibit No. 39

These “expansion joints” are detailed in the original construction documents and are built as drawn, but they do not extend through the roof system as required. These openings will allow warm, moist, unconditioned air into the roof system from below.


Exhibit No. 40

The paint finish on exposed metal deck was in poor condition in the lockerroom areas.

Exhibit No. 41

Evidence of water intrusion is visible on the light fixtures in the computer lab. These leaks are reported to have been occurring for an extended period of time.


Exhibit No. 42

Damaged ceiling tiles were encountered in multiple rooms. Approximately 25-30 tiles were affected. This location was reported as an active leak in the computer lab and is directly beneath the pitch pocket in Exhibit Nos. 10&11.

Exhibit No. 43

The roof structure in the Drill Hall and Firing Range is tongue & groove Tectum panels over steel framing.


Exhibit No. 44

Approximately 6-10 Tectum panels were identified in the Drill Hall as having shifted downslope from their original position. The panel edges are tongue & groove which appear to have separated to varying degrees.

Exhibit No. 45 One panel was identified with physical damage, but it does not appear to affect the performance of the system.


Exhibit No. 46

Significant water leaks have occurred in the firing range. Many cementitious wood fiber panels have incurred water damage and no longer appear to be structurally sound. Any panel which has become wet should be removed and replaced. Foot traffic on damaged areas should be restricted.

Exhibit No. 47

In one closet, a wall has been partially removed to an adjacent closet. The remaining masonry is not supported and is showing evidence of movement and deflection. Cracks have formed on both sides of the remaining masonry and separation is evident beneath the roof deck.


DISCUSSION

Based on our inspection of the Memphis Armory, the overall condition of the roof system was found to be fair. Active leaks were reported in the Firing Range, Computer Lab, and in 2 different offices at the front of the Readiness Center. Evidence of repeated moisture intrusion is visible in numerous rooms and hallways throughout the building. Over the classroom and administration areas, the building roof structure consists of steel joists and steel roof deck. Above the firing range and drill hall, the roof system is a tongue and groove cementitious wood fiber board on steel trusses and purlins. A Soprema multi-ply modified bitumen roof system is installed over the entire facility. A manufacturer’s roof system warranty is in effect until April 2030. Drainage on the all areas is provided by gutters and downspouts which spill to grade. The roof system is in overall good condition. Minimal granule loss and membrane damage were found. Some delamination was found between the cap sheet and base ply, but no leaks were reported in these areas. Above the front entrance foyer, a large blister was found that had filled with water, but no leak was reported beneath. Some of the blisters intersect seams in the membrane and have started to pull apart. It appears that the base sheet has been run perpendicular to the cap sheet. Multiple flashing details do not conform to manufacturer's requirements or standard details. The hot stacks are not properly flashed and a plumbing vent stack was found with a flashing boot intended for use on a metal roof. Pre-fabricated pitch pockets have been used on some penetrations and do not appear to be properly formed or filled. A leak was reported in the computer lab directly beneath one of the pitch pockets which had a large void in the filler. Around the perimeter of all roof areas, a raised gravel stop was used in lieu of a low-profile drip edge. This has caused water to back-up and stand on the roof surface. Several areas of soft insulation were found along with significant staining of the roof membrane. The workmanship of this edge metal was very poor with several openings through the metal to the fascia and nailers beneath. This same gravel stop was used in conjunction with foil-faced flashing on the high roof areas. The foil faced flashing has failed in multiple locations exposing the asphalt beneath. Since the asphalt used in sheet goods is not UV stable, degradation and further failure of the foil facing will continue. The cap sheet on the high roof area has been installed parallel to the slope of the roof. Manufacturer’s instructions state that the cap sheet should be “…installed perpendicular to the roof slope, shingled to prevent back water laps.” Further, the manufacturer does not recommend installation using hot asphalt on slopes over 3/4:12. The high roof area was measured at 9° which is 2:12. No mechanical termination or back nailing was used when installing the cap sheet and the membranes have started to slide down the roof. Separation is evident at the end laps and along the ridge. The exterior walls of the readiness center consist of load bearing masonry walls with brick veneer. The brick is in overall good condition. Less than 20 LF of masonry joints and 6 bricks were noted to require repair or replacement. However, the exterior masonry control joints are in poor condition. The sealant is dry, brittle, and cracked, and can allow moisture to enter the exterior wall system. Some staining is present on the exterior facade as a result of leaks behind the gutters and from gutter seams. Soil erosion has occurred at many lawn areas where the downspouts discharge to grade level. The interior masonry walls were in fair to poor condition overall with cracks observed in multiple locations. Approximately 450 LF of damaged masonry joints and 20 damaged masonry units were identified. One location was found in which the opening has been knocked through a CMU wall. We are not aware by whom or when the work was done, but the CMU’s left in place above the opening are unsupported and should be corrected as soon as possible. The precast concrete panels on the front entrance have several areas of spalling and cracking. They appear to be the result of "rust jacking" where the fasteners have started to corrode. When metal corrodes, it increases in size. This increase in size has caused the cracking and spalling.


Several ventilation fan louvers were found to have failed. On the back of the firing range, the louvers have corroded and are stuck in the open position. On the high wall of the drill hall, the two ventilation louvers are likewise corroded. The individual vanes have started to separate from the frame and are lying on the roof surface. Both of these conditions allow a direct path for wind-blown rain into the building and into the wall assembly. The steel roof deck over the administrative and classroom areas is in fair condition. A large number of areas show evidence of corrosion and moisture damage. The original construction details show expansion joints in the roof system. The expansion joints created a continuous gap in the roof deck with no seal to keep out warm, moist, unconditioned air from the interior. The expansion joint did not extend through the roof system which can result in cracking, damage, and leaks in the modified bitumen membrane. Likewise, the abandoned equipment mounts for the solar collectors which were removed, are still in place and penetrate the roof deck. Large gaps around the supports allow air into the roof system. Air penetration into the roof system can cause condensation, corrosion of the roof deck, and deterioration of the insulation composite. The tongue and groove cementitious wood fiber roof deck in the drill hall and firing range is in fair condition. Several of the panels appear to be displaced down the slope. Some tongues and grooves are not fully engaged which can compromise the structural integrity of the system. One panel was found to be cracked and one panel showed physical damage in the drill hall. In the firing range, evidence of repeated leaks is visible. Approximately 10-15 panels appear to be affected and show deterioration. Any panel which has become wet will lose its structural strength even if allowed to dry. We did not conduct any type of destructive examination to verify the attachment of the panels. Typically a combination of screws, clips, and adhesive is used to secure the panels in place. Screw spacing is dependent on uplift resistance and shear capacity of the panel attachment. Since it is apparent that some of the panels have moved, further evaluation by a licensed structural engineer may be advisable. Replacement of deteriorated panels is necessary. This type of deck panel may be removed and replaced only from above which will require removal of the roof system.

CONCLUSION & RECOMMENDATIONS

It is evident that the readiness center has experienced roof leaks and interior damage. The existing roof system is under warranty until 2030, but based on our inspection, several unusual and irregular conditions were observed which typically are not Soprema’s approved details or installation techniques. It is recommended that leak reports be filed with the manufacturer, requesting repairs be made under the roof warranty. Further, it is recommended that a manufacturer’s technical representative inspect the roof to determine if the application and condition of the roof are acceptable. We did not observe damages or conditions which could be attributed to Owner-caused traffic, abuse or neglect. Rather, the deficiencies and resulting leaks which we found appeared to be due to poor or improper installation. Defects such as blisters which cross or affect seams should be removed and repaired. The raised gravel stop on the roof edges, deteriorated foil-faced flashing, lack of back-nailing, and vertically-run sheets are manufacturer issues, which in our opinion, also should be covered under the terms of the warranty. If any deficiencies are determined to be excluded from the warranty, the Owner will be responsible for any repair costs, including manufacturer inspection fees. The roof deck expansion joint locations should be carefully and regularly monitored to detect any damage to the roofing membrane which might develop along the line of the joint. We do not recommend disturbing the intact roof unless movement begins to damage the roofing. This type of defect is not a warranted item. The exterior brick masonry appeared in satisfactory condition with only limited repointing of exterior masonry joints necessary. It is recommended that all exterior masonry control joints be cleaned out and resealed. Spot repair of the spalled concrete panels at the front entrance will be necessary to prevent further deterioration. Repairs should include treatment of the exposed steel reinforcement to arrest rust, and concrete patch materials should include a bonding agent to prevent recurrence of spalling. Once all masonry repairs are complete, it is recommended that all exterior brick surfaces be cleaned. Interior masonry has numerous cracks and broken CMU. It is recommended that deficient mortar joints be repointed and broken CMU replaced. We found no evidence that the cracking was recent or still active. The new wall opening between rooms is not structurally sound and requires a lintel and dressing out. We recommend that this be done immediately.


Deteriorated metal roof deck was found in several locations. Replacement can be performed only if the roof system is removed from above. Most of the damage appears to have occurred around roof fasteners which penetrate the deck and have been exposed to water from roof leaks. It is recommended that once all roof leaks are corrected, all rusted areas should be cleaned and ground smooth, primed, and repainted. Loose and deteriorated cementitious wood fiber roof deck panels (commonly referred to as Tectum) were found in the Drill Hall and Firing Range. It is recommended that any deteriorated panel be removed and replaced. Since the panels can be removed only from above, this will require removal of the roofing and insulation also. The water damage appears confined to the Firing Range, so as a practical matter, roof replacement is recommended on this entire area. As illustrated in the exhibits, further investigation of the Drill Hall deck is recommended. Water leaks are occurring behind and from the perimeter gutters resulting in staining the exterior brick masonry. The combination of standing water behind the gravel stop and failed gutter joints appear to be the source of the water. It is our opinion that the gravel stop and gutter should be removed and replaced as part of the manufacturer’s responsibility. Interior finish repairs are recommended to include removal and replacement of water-damaged acoustical ceiling tile and repainting the underside of the exposed metal deck. Preparation, priming, and correct paint of the existing metal surfaces are essential to ensure that the existing paint deterioration does not recur.
