FLEX TPO PLUS

ADHERED ROOF MEMBRANE

INSTALLATION GUIDE

This guide is intended to be a point of reference in assisting the Flex Authorized Applicator with installing

the Flex TPO Plus Adhered Roof System in accordance to the basic requirements of current Flex Details

and Specifications for acceptance of the installation for a roof warranty application. The installer should

always refer to the project specifications for details and application requirements for each unique roof

system installation.

1.0 Substrate Preparation:

Defects in the substrate surface must be reported and documented to the Building Owner’s

Representative for assessment. The roofing contractor shall not proceed with the roof system

installation until the defects in the substrate have been corrected.

A. Recover or Retrofit Roofing Applications: The project specifier shall identify

damaged or wet insulation areas. The insulation as indicated shall be cut out and

removed from the roof area. The removed insulation shall be replaced with new

insulation of the proper size to fill the space (flush with existing surface ±1/4”)

and obtain a relatively smooth surface acceptable for the installation of the new

roof system.

B. Existing Single Ply Roof Membranes: If the existing membrane is to be left in place it

must be cut into sections no larger than 100 square feet per each section.

All flashing must be removed at the perimeter edge, roof drains and roof penetrations.

C. Gravel Surfaced Built Up Roofing: The loose gravel must be removed either by

vacuuming or power brooming. The surface must be leveled to prevent the

insulation or recover board from bridging.

D. All Projects: The substrate must be smooth and relatively even without high spots or

depressions. Any accumulated water, ice, or snow must be removed to prevent

the absorption of moisture in the new roofing components and roofing system.

The substrate shall be clean and free from debris and any other foreign material.

E. Lightweight Insulating Concrete: Flex FB membranes may be adhered directly to

approved cellular or perlite insulating concrete. The insulating concrete deck must have a

minimum compressive strength of 225 psi.

1.1 Vapor or Air Barrier Installation:

Install the barrier in accordance with the manufacturer’s written instruction and the

project specifications for the installation of the specified product.
