Exposed Roof with Foot Traffic
An exposed mineral-surfaced roof engineered for regular access — traffic carried on protected walkways, not on the membrane.
One System, Built to Work Together.
Many exposed roofs are not left alone after handover. Technicians reach plant and tanks weekly, solar arrays need cleaning, antennas need service. A mineral-surfaced membrane is made to face the sun — it should not carry daily footfall unprotected.
Insutech builds these roofs on heavy mineral-surfaced APP membranes and adds defined walkway zones — protection boards or paving pads along the routes people actually use — so the traffic loads land on the protection layer while the membrane keeps doing its job underneath.

- Solar panel service routes
- Water tank and antenna access
- Utility and telecom roof platforms
- Exposed roofs over occupied buildings

Layer by Layer.
- 01
Deck Preparation
The structural deck is cleaned and levelled, with falls directed to drainage points.
- 02
Bituminous Primer
Primed surfaces guarantee full adhesion of the torch-applied system.
- 03
Base Membrane
A plain APP base layer is torch-applied over the primed deck.
- 04
Mineral Cap Sheet
A heavy mineral-surfaced APP cap faces sun and weather directly as the finished roof.
- 05
Walkway Protection
Protection boards or paving pads define the access routes and carry the foot traffic.
01Faces the Sun Directly
Mineral surfacing shields the bitumen from UV, so the membrane is the finished roof.
02Traffic on the Protection
Walkway zones take the loads and abrasion, keeping the membrane out of harm's way.
03Serviceable for Years
Access for maintenance is designed in from day one, not improvised over a finished roof.
04Simple to Extend
New routes can be added later by laying additional pads over the same exposed system.
