The E-Z Riser Process

THE E-Z RISER EDGE

The E-Z Riser Process invented the Roof Raising Industry, and has been the industry standard since 1972. Others have come and gone, using haphazard lifting methods, trying to imitate its success. But only the E-Z Riser system offers the following:
100% Safety No “Swiss Cheese” Slabs: Not An On-The-Job Training Exercise Fully Occupied Lifts
Methods have been attempted which separate the roof from its support structure, then fight wind and gravity with guy wires and building blocks. Only E-Z Riser keeps the structure intact, thereby maintaining and even improving stability and integrity throughout the entire process. Any lifting method dependent on guy wires needs an array of anchor bolts, leaving “swiss cheese” holes in the floor slab. Only E-Z Riser uses the building’s existing structure, maintaining stability and avoiding floor damage. E-Z Riser work crews are experienced roof-raising experts. They fabricate the steel in-house, deliver and install it, accomplish the lift, and enclose the new height. Most crew members have been performing this work for over 10 years. We don’t license the process or rent out proprietary equipment to others. The E-Z Riser Process is so safe and secure that it is performed even in occupied warehouses, without disrupting ongoing operations, and without needing to vacate the roof-raise area.

Structural engineering

Complete structural engineering is provided by licensed professional engineers. The included stamped drawings show compliance with building codes, including provisions for seismic, snow load, and wind shear considerations where applicable.

Wrap vertical columns with support “Sleeves”

Interior vertical columns are enclosed within steel “sleeves” that allow the original columns to rise as they lift the roof. The sleeves remain in place to provide new and stronger lower support.

Attach “Lifting Columns” to perimeter columns

Perimeter columns are fitted with additional telescoping “lifting columns” that raise the roof perimeter and remain as integral parts of the lifted, strengthened structure.

Install lifting equipment; Separate walls from roof

Proprietary E-Z Riser collars, clamps, and hydraulic lifting mechanisms are installed at each prepared column. This system avoids the need for temporary shoring and the resulting floor damage. The building is never separated from its foundation and is never subjected to instability.
The E-Z Riser Process

Install temporary utility extensions

Local contractors disconnect sprinkler riser, and install temporary extensions of lighting, power, HVAC, and drainage lines, allowing these utilities to remain uninterrupted during lifting.
The E-Z Riser Process

Actuate lifting equipment

Lifting equipment is activated, adding one foot of additional roof height every hour, in a precise and even interval, preserving roof condition and pitch.

Install insulated steel paneling (optional)

Insulated steel paneling is installed to enclose the newly created height, if requested. This wall system provides an attractive exterior finish and a light-reflective interior surface. The paneling provides long-term durability and energy-saving thermal insulation.
