• Esthetics of the project (high expectations of customer).
• Logistics: stock and transport of materials during installation, access, etc.<
• Adverse weather conditions for fully adhered system: wind, rain, high relative humidity.
• Adverse working conditions: shape of roof, wind, etc.
• Security: roofing crew, etc.
• Development of esthetic sheet lay-out.
• Design of roofing details: gutters, roof edge, etc.
• Training of roofing crew.

The Firestone TPO Roofing System for the new Carrasco Airport terminal has been designed in accordance to FM – Specs and offers a 1 – 150 wind uplift rating.
Firestone B.P. manufactured specifically for this project a new 8 ft wide TPO flashing for detailing of the curved roof edges.
Finally Firestone feel very confident about the end result and are offering a 20 year Red Shield Warranty to the customer, covering both materials and labor of the Roofing System.
