Scope of Work
The existing roof was a 1-layer modified bitumen roofing system over a lightweight concrete deck with steel pan below it. The roof could not be mechanically fastened due to failure of a pullout test. Parsons Roofing Company removed the existing roofing system and replaced it with a Polyiso base and tapered EPS insulation system. This roofing company also utilized a wind-vented system from 2001 Company to achieve a manufacturer’s 20-year NDL warranty. The roof was unable to be fully adhered due to possible moisture in the deck from years of saturation.
