Summary
New roofing system will be an epdm (rubber) membrane system installed on a recovery board, over top of a multi-layered r30 insulation system. An r30 insulating value is the code minimum requirement and will provide significant reduction in heat loss in the portion of the building receiving the new roof. This will have a positive effect on the energy usage in that portion of the school. Additionally, all roof drains within the replacement area will be replaced and connected to the existing-to-remain drain piping under the roof. all flashing and roof edge metal will also be replaced in the project roof area. the new roof will be designed to achieve a base id 10 year total roof system warranty and we are recommending the inclusion of an alternate bid for the possibility of a 30 year total roof system warranty.
