PEDESTAL SUPPORTS

Pedestal supports
are the proper technology

for elevating a flat and level
walking surface over
a low-sloped roof system.

Advantages of pedestal-supported decks

  • Highly adjustable pedestals conform to a wide range of heights and slopes

  • Water and air flow freely beneath – no impediment to roof drainage

  • Many attractive material and design options for surface pavers that work with pedestals

  • Construction is gentle on roof membrane and offers longterm protection from laceration, excess pressure points, and other damage.

  • Weight of deck and amenities is distributed evenly across roof structure

  • Nothing to rot or decay. Materials can last for decades.

  • Provide easy access beneath the deck for cleaning and maintenance of drains and roof.

  • Deck blocks nearly all UV radiation, reliably extending the life of the roof membrane.

  • Allows space for utility lines beneath deck and portions of deck can be removed and replaced without demolition and waste. 

  • Pedestal decking systems can be accessorized for wind uplift prevention and snow melt.

  • Pedestal-supported decks can be installed over other exterior surfaces, including pavement, old concrete, gravel or lawn.

  • Long-plank decking can be installed over traditional joists that are elevated and leveled on pedestals​

Bison pedestals and wood tiles

Concealed beneath the finished deck surface, pedestals are the ingenious technology for elevating a flat and level walking surface over a low-sloped roof system. Dozens, hundreds or thousands of pedestals are needed (according to size of the deck) – each selected and adjusted to fit precisely in its proper position.

​

A dozen different pedestal brands are available on the market, each performing three basic functions:​

  1. Elevate and level the deck by adjusting for changing heights across the roof drainage system

  2. Compensate for varied roof slopes to maintain a stable, flat walking surface

  3. Evenly distribute the load of the deck across the roof structure 

​

Each brand varies in how to perform these tasks – and some perform better than others. I'm happy to work with whatever pedestal system is selected for your project.  

SELECTING TYPE, SIZE AND QUANTITY

Each deck requires a customized pedestal "kit" specific to the particular measurements and circumstances of the rooftop and the dimensions of the selected surface pavers. I've calculated the materials needed for hundreds of decks and know how to get it right.

To safeguard the roof membrane, a protective slip sheet should be inserted under each pedestal.
