Projects: Roof Project at Sagamore Hills Elementary School – 1865 Alderbrook Rd NE, Atlanta, Ga
Subject: The following proposal outlines the scopes of work to install TPO roof systems per the
manufacturer’s specifications.
Delivery, Storage and Handling:
• Deliver products in manufacturer’s original containers, dry, undamaged with seals and
labels intact.
• Store products in weather protected environment, clear of ground and moisture.
• Materials will be always stored evenly on the roof.
• Materials will be covered, protected and properly secured from the elements.
• No materials will be placed within a ten-foot perimeter of the buildings open edge.
• Material Safety Data Sheets (MSDS) to always be on site.
• Keep combustible materials away from ignition sources.
Project Preparation:
• Perform a pre-job inspection with the building owner representative to determine best
set up area, dumpster locations and debris removal locations.
• Furnish and install all required safety equipment per Core Roofing Systems and OSHA
guidelines.
• Upload all materials to complete the project in accordance with good roofing practices.
System Installation: Sagamore Hills Elementary School (Approximately 49,100 Sqft)
• Remove the existing roofing down to the existing structural concrete decking. Clean all
debris from the decking and allow NOVA Engineering to perform their chain drag test
and core sampling to determine if any structural concrete repairs are necessary.
• In the instance NOVA Engineering finds areas of back decking, Core will remove any
loose concrete decking to create a suitable surface for the installation of new Quik Set
Concrete Grout. All deck repairs performed by Core Roofing Systems will be charged as a
change order at a unit cost of $60.00 per Square Foot.
• After all testing and decking repairs have been completed and cured, we will install new
modified base sheet and adhere it to the concrete decking using moisture cured
adhesive per the manufacturer’s warranty requirements. This layer will act as the vapor
barrier.
• Provide and install all new wood nailer around the perimeter of the roof and at all
expansion joints to account for the new roof height. This allows for proper termination
of the new edge metal and TPO membrane.
• Provide and fully adhere (2) layers of 2.0” polyisocyanurate insulation over the existing
decking. All insulation will be installed using low-rise insulation adhesive at the
application rate required by the manufacturer to meet warranty requirements

• Provide and fully adhere new 1/8” per foot fully tapered insulation over the newly
installed base insulation to provide adequate slope to the new roof system, allowing for
proper water shed. The tapered insulation will be installed using low-rise insulation
adhesive at the application rate required by the manufacturer to meet warranty
requirements
• Provide and fully adhere new ¼” per foot tapered insulation crickets between the
primary drains to direct all waterflow to the drains, allowing for proper drainage. All
insulation will be installed using low-rise insulation adhesive at the application rate
required by the manufacturer to meet warranty requirements
• Provide and fully adhere new .060 TPO membrane over the newly installed
polyisocyanurate insulation using the manufacturer’s standard solvent based bonding
adhesive per the manufacturer’s warranty requirements.
• Flash up all perimeter parapet walls with new .060 TPO membrane and terminate into
the walls using termination bar and counterflashing.
