ROOF CONDITION ASSESSMENT REPORT

CHILLICOTHE VA

BUILDING 31 – SPD ADDITION

INTRODUCTION

RDA Group Architects [RDA] visited the SPD Addition Roof at Building 31 on the Chillicothe VA Campus on September 19, 2025 to review the existing conditions related to the roof system building enclosure components.

RDA was engaged by the VA to provide an assessment of the existing conditions, specifically related to the roof system deficiencies where the roof system has become loose and detached from the structure. RDA will provide a short and long term forecast for the anticipated repair and/or replacement work that will be required due to the conditions. This report is the result of the field investigation.

BACKGROUND

The SPD Addition was constructed approximately 10 years ago. It is a 1-story addition with medical uses within the space. The addition is located at the north side of the existing building.

The building is a protected steel structure with metal framed walls. The roof deck is a metal deck with concrete topping over [designed for a future second floor]. The roof system is original to the building.

ROOF SYSTEM DESCRIPTION

The addition generally contains [2] roof areas as outlined on the below roof sketch. There is a total of approximately 12,500 SF of roof among all [2] areas. Refer to the roof key plan below for identification of the roof areas.

RDA cored the existing roof system as part of the investigative work. The roof composition is generally as follows [listed from top to bottom]:

• 60 mil EPDM roof membrane [fully adhered]

• Tapered polyisocyanurate insulation [set in low rise foam adhesive]

• Concrete roof deck [flat – no slope]

RDA was able to review the original building drawings and roofing submittals as part of our investigation. Generally, it appears that the building was constructed as designed. The roof system installed is Carlisle, and currently under warranty per information received from RDA.

The roof is accessed from the penthouse at the adjacent portion of the building.

The roof areas ‘A’ and ‘B’ are bound by parapet walls at all sides.

The parapet walls are 18” to 24” in height, framed with metal stud framing, and capped with a metal coping. The roof system extends up and over the top of the parapet wall and is terminated at the exterior face of the parapet under the coping.

Primary roof drainage is via internal roof drains. The roof slopes via tapered insulation in two directions with tapered insulation saddles between the roof drains / along drain lines. Secondary [overflow] roof drainage is via scupper openings in the parapet walls. RDA did not verify adequacy of the drainage systems as part of this condition assessment. It is assumed that the drainage is properly sized for the respective roof area.

RDA inquired with the building facilities representative, Trent Vartorella, who indicated that there have been no leak issues with the roof. It should be noted that considering the construction of the building, it is possible for there to be water intrusion issues that may go undetected inside of the building.

OBSERVATIONS / ROOF CONDITIONS

1. The primary purpose for the roof condition assessment is to review the obvious displacement of the insulation

/ roof system which are creating displacement of the insulation / raised areas within the roof system.

2. The EPDM membrane itself is generally in good condition considering the issues experienced. It was noted that there are what appear to be air pockets between insulation boards as well as additional mole runs within the field of the roof.

3. RDA cut [4] cores into the existing roof system as part of the investigation. RDA patched the same at the conclusion of the site visit.

3.1. Core #1: The location selected is in an area of displaced roof system. The EPDM membrane was not well adhered to the top layer of insulation / facer [this could be from someone stepping on the roof system with the insulation being able to move, detaching it from the insulation]. There are [3] layers of insulation at this core location, which total approximately 6” in thickness. The insulation was wet / damp to the touch, particularly with the middle layer of insulation. The [3] layers of insulation were still adhered to each other via the low rise foam adhesive. The bottom layer of insulation was detached from the concrete deck with a void of approximately 5”.

3.2. Core #2: The location selected is at an area of intact roof system. The EPDM membrane was adhered to the top layer of insulation / facer. There are [3] layers of insulation at this core location, which total approximately 6” in thickness. The insulation was dry. The [3] layers of insulation were still adhered to each other via the low rise foam adhesive. The bottom layer of insulation was adhered to the concrete deck. No void present below the insulation.

3.3. Core #3: The location selected is in an area of displaced roof system. The EPDM membrane was adhered to the top layer of insulation / facer. There are [2] layers of insulation at this core location, which total approximately 3” in thickness. The insulation was relatively dry, but showed signs of being wet / damp, particularly between the layers of insulation. The [2] layers of insulation were still adhered to each other via the low rise foam adhesive. The bottom layer of insulation was detached from the concrete deck with a void. There was noted positive air flow from within the cavity under the roof insulation.

3.4. Core #4: The location selected is in an area of displaced roof system. The EPDM membrane was adhered to the top layer of insulation / facer. There are [2] layers of insulation at this core location, which total approximately 3” in thickness. The insulation was wet / damp to the touch, particularly at the bottom layer adjacent to the concrete deck. The [2] layers of insulation were still adhered to each other via the low rise foam adhesive. The bottom layer of insulation was detached from the concrete deck with a void. There was noted positive air flow from within the cavity under the roof insulation.

4. The bond failure between the concrete deck and the insulation is resulting in the insulation being raised off the deck. This is impacting the ability of the roof to drain properly.

5. It was noted that the areas of failure appear to be located adjacent to the primary roof drains, emanating from the drain out either side of the drain in the direction of the primary tapered insulation slope. This condition is evident at each roof drain to varying extents.

6. The roof contains a lightning protection system with lightning rod aerials located on the parapet walls and grounding leads into the building through the roof system.

RECOMMENDATIONS / SUMMARY

Generally, a fully adhered EPDM roof system should last in excess of 20 years. The roof is currently approximately 10 years old and is at the point of failure within the roof system itself, not necessarily the actual EPDM membrane. These failures are impacting and shortening the service life. The current roof conditions leave the roof at risk of failure during an extreme wind event as the insulation is no longer attached to the concrete roof deck in multiple areas. Additionally, the roof system warranty that is currently in place with Carlisle is a leak warranty. Since there have not been leaks into the building, the warranty has not come into play.

RDA believes that the failures could be a result of the quality of the original bond between the concrete deck and the first layer of insulation. RDA cannot confirm the temperature / weather conditions [50 degrees and rising] at the time of original installation; the conditions of the concrete deck [temperature, relative humidity, etc.]; if the insulation was properly weighted in place during the cure time of the adhesive [which varies based upon the temperature / humidity, etc.]. RDA only observed [1] bead of adhesive at the roof deck at Core #1, and it appeared less than the 1/2" to 3/4” wide spacing recommended by the manufacturer. It appears that there is positive pressure within the building which may be the root cause for the failures. Two of the cores taken had positive air flow from within the cavity. There are not but a couple of penetrations on the roof with the exception of the roof drains. The failures generally emanate from the proximity of the roof drains outward into the roof system. It is likely that the original bond between the concrete and the first layer of insulation was compromised by weather, proper adhesive application rates and spacing, lack of proper weighting of the insulation during curing thereby weakening that bond from the start.

RDA recommends replacement of the roof system in its entirety. The bond of the adhesive is deficient between the concrete deck and the bottom layer of insulation in multiple locations [at areas of failure]. The only way to effectively address this issue is to remove all layers of the insulation to the deck and start with new. RDA recommends, prior to the roof replacement, evaluating the air seal at the roof drain openings in the roof deck. If the building is under positive pressure [as was noted on-site] and this positive pressure is able to get up and around the roof drains, it could continue to put pressure into the roof insulation, and thereby create the failures exhibited. The approach for the new roof system would be the same with tapered insulation adhered in place and a fully adhered EPDM roof system.

For the short term, additional ballast / weight could be installed over the EPDM membrane to assist in preventing a blow off in an extreme weather / wind event. Considering the building is designed for a future second floor, the additional weight should not pose an issue.

Please contact me if you have any questions regarding this conditions assessment report.
