Learning Places & Growing Spaces EXECUTIVE SUMMARY: Name: Cheatham K‐8 School Laveen Elementary School District Location: 4725 W. South Mountain Ave.
Laveen, AZ 85339 Roof Size: Foamed in Place Roofing: 23,821 SF Built‐Up Roofing: 4,160 SF Standing Seam Metal: 35,118 SF Modular Classrooms (Foam): 7,200 SF Restroom building (BUR): 1,600 SF Total: 71,899 SF Inspection Date: November 14, 2014 History: The school district reports miscellaneous leaks have been observed with greater frequency, particularly after the most recent storms. A general visual survey of the roof was performed without any specific focus on any one area of the roof upon arrival. Visual survey of interior spaces was not conducted. Recommendation: As a result of our survey, our recommendation is to repair damage, clean and recoat foam roofed areas. At BUR we recommend applying white acrylic coating. At metal roofing and flashing re‐seal perimeter and penetrations. The new cementitious coating with proper and timely inspections, repair and maintenance, should provide service to the District for ten years. Budget: Based on preliminary subcontractor pricing with a ten year manufacturer’s warranty anticipated cost to replace roof is as follows: Foam with Cementitious Coating: $ $69,000.00 Standing Seam: $4,000.00 BUR at Mechanical Enclosures: $15,000.00 BUR @ BLDG G: $5,600.00 Repair Foam @ Portables: $10,800.00 Sales tax & Bonds: $6,264.00 Total estimated Cost of Construction: $110,664.00 Additionally, yearly inspection and maintenance to remove leaves, debris and sports equipment from drains and roof surfaces should be budgeted and performed along with proper patching and repairs of any damage to the coatings.

CONSTRUCTION: Visual inspection confirms the flat roof areas to be spray foam coated with a white cementitious layer. Parapet wall and mechanical curb flashings have been constructed out of the same sprayed foam and protective coating. Roofing as‐builts indicate the spray foam to be R‐30 thickness.
Core sampling of the roofing was not deemed necessary since the insulation appears to be good condition. Drawings do not indicate if the foam insulation is built up or applied over mechanically attached board insulation.
Roof Warranty indicates the roof system carried a 10 year warranty from the date of substantial completion, January 16, 2003. This makes the roof system out of warranty for almost 2 years. An executed copy of the warranty is attached as an exhibit. The attached warranty does not apply to the modular classroom buildings or restroom building.
Parapet walls average 42” to 72” in height at the various roof area perimeters. Coating extends up the back side of parapet walls 12‐16”. The uncoated CMU is painted. A metal coping was installed over the parapet and mechanically fastened to the wood nailers.
Roof top packaged air conditioners are arranged randomly at foam roof area and paired up on sloped BUR mechanical enclosures as at sloped metal roofs. All RTU’s are placed on factory roof curbs and flashed with BUR or cementitious coating based on location. Penetrations are flashed with metal collars and sealed at the pipe penetration with sealant. Walk pads are not provided.
Roof slope is generally 1/4” per foot at low slope roofs. Crickets are provided at all equipment and to direct run‐off to internal roof drains along the roof perimeters. Overflow is handled with scuppers through the face of the parapet walls.
OBSERVED CONDITIONS:
Overall roof was clear of leaves, debris and dirt. Some silt was observed where water ponds in depressions however the pond areas where very shallow and infrequent.
Damage from birds pecking on the foam roofing was noted at the perimeter of the Administration Roof area where roof terminates at a gravel stop. This was the only place where bird damage was observed. No pigeons or pigeon debris was noted.
Numerous patches were observed in the cementitious coating where previous repairs have been made. Most patches appear as lighter coating.
Large blisters were observed at the round building element over the Administration Area and in the roof area southwest of the Multi‐Purpose Room/Gymnasium. The blister area near the gym occurred in a line of almost continuous blisters the length of the roof.
The Gymnasium Building was retro‐fitted with ballasted photovoltaic panels sometime after the building was opened. It appears the foam roof over the Gym was patched and re‐coated with new cementitious coating prior to installing the solar panels. This area will not require recoating.
Gas piping, electrical conduits and condensate drains are supported by plastic or wood blocking. Plastic supports and piping are in good condition. Wood supports are undersized and weathered.

Prefinished metal coping is in good condition and should not need to be removed to re‐roof the facility.
At the roof area north of the MPR/GYM the roof at the drains were reworked as part of an addition and the roof drain strainers were not re‐installed. Strainer basket rings will need to be re‐installed prior to re‐coating the roof.
A new Gym and Classroom addition has been constructed on the east side of the existing MPR. The new addition is not part of the assessment.
Two modular classrooms also have foamed roofing but appear to have been installed at a later date. These roofs had some small cuts in the coating. Due to their proximity to the play grounds some rocks and balls were observed on the roof. There were also cut‐outs in the EFIS parapets where parapet ladders have been mounted that need to be sealed. These buildings were not covered under the original warranty.
A small restroom building was also constructed at a later date to serve the Modular Classrooms and play grounds. This building has a built‐up roof that appears to be fair condition. It would make sense to coat this roof at the same time as the other BUR roof areas.

RECOMMENDATIONS:
This roof has been in place for 12 years and is currently leaking at fractured blisters and sealant voids. The roof coating is past its warranty period and useful life. Most concerning are the numerous blisters and fractures identified during the assessment. These are susceptible to additional damage and moisture infiltration. The only remedy for the blisters is to remove the delaminated areas and patch.
The existing insulation is in good condition, slopes are adequate and uniform, and crickets appear to be unobstructed. Based on the condition of the substrate we recommend cleaning, patching and re‐coating the entire foamed in place roof area with a cementitious coating capable of providing a new warranty.
Emc2 has access to the contractor’s record drawings. Dead load appears to be adequate for the additional cementitious coating. Loads will be verified upon approval of the project.
The estimated cost of the retrofit is approximately $4.00 per Square Foot for 36 mil elastomeric coating with granular coating at Foamed Roofing and $3.50/SF for 24 mil white acrylic coating at Built‐up Roofing.
Cost of Neglect:
Without the recommended roof replacement the leakage will intensify as the existing blisters continue to fracture and new blisters form. As leaking increases, consequential damage will occur to roof insulation and metal decking, resulting in a costlier roof replacement. Instead of recovering the existing roof a full tear‐off may become necessary in order to inspect the metal decking for damage. Additional risk exists with damage to interior building spaces and finishes. Full tear‐off is estimated to add an additional $3.00/SF to the roof replacement.
