When our clients think about their roof, they usually think about it as one whole structure that works to protect the interior of their building. However, a roof is actually made up of multiple segments that work together to stabilize and protect the structures beneath it. Repairs, replacements, and new roofing construction are often not just about installing the right membrane, but also encompass expert work in the fields of masonry, demolition, and interior tarping for safety (to name a few). If you’re a building owner, you know how difficult it already is to find a roofer you can trust. That’s why the Elite team comes equipped with trusted partners that are able to take care of any extras that may be required for your roofing job.
This week, we’re featuring Nusens, one of our most trusted partners. We’re letting you in on some of our most successful projects together, and how our teams function in order to ensure that your project goes smoothly, and your roofing project is as safe and worry-free as possible.
Project 1: Masonry At 585 Canarctic Drive
The scope of work for this 36,830 sq ft roof was extensive. Not only was a full roofing replacement needed, but masonry parapet walls above the roof were exposed and at risk of falling off the building. This roof was in need of a comprehensive plan to resolve building envelope issues, so Elite worked together with Nusens to tackle these elements head-on.
How We Did It:
During the initial inspection, it was discovered by the Elite team that the top course(s) of split rib blocks on the parapet walls were loose. This was of course a hazard for both the building structure and for any repairs that would need to be carried out on the roof itself.
In order for metal copings and the new roof membrane to be installed, any loose masonry would have to be dealt with first in order to avoid major structural issues and future roof failures. The team at Nusens first repaired the masonry, and once the parapet walls were solid, the roof membrane was installed on top. The result was a sound roofing system that will stand the test of time.
The main concern for both teams with this particular project was the reinforcement of the masonry blocks. In order to ensure that the Elite team had a strong foundation to lay down the roofing membrane, the Nusens team:
- a. Removed the top course using mortar chipping saws (eliminating dust creation).
- b. Drilled rebar dowels into the solid courses.
- c. Cleaned the existing masonry blocks, which included removing any mortar or grout from them.
- d. Laid the newly cleaned blocks with a non-shrink grout to stabilize.
Project 2: Interior Tarping at 5 Tilbury Court
5 Tilbury Court was a unique project for the Elite team. The 75,793 sq ft building housed a factory that produces non-woven fiber batting for use in the upholstery, bedding, and filtration markets, making this an extremely flammable work environment.
How We Did It:
The Nusens team installed an anti-static, high-temperature resistant ceiling containment system before Elite began re-roofing operations. Utilizing aerial work platforms with added grounding, along with CSA certified tools and added worker grounding, a ceiling dust and fire containment system was installed prior to Elite Roofing’s removal and replacement of the old rusted metal deck.
The old roofing assembly was composed of multiple layers of different, often incompatible, materials. The Elite team also repaired/replaced localized areas of the metal deck substrate with materials that worked seamlessly with the already installed panels.
The main challenges for this project were fire safety and factory safety. For this particular repair, the team would be repairing electrical connections, and the factory would be open during the repairs. This meant that we had to take every precaution to ensure that none of our work interfered with the factory operations below.
Because of the high quality and extensiveness of the tarping coverage, the Elite team was able to complete this roofing replacement successfully, without incident, without shutting down manufacturing. If you’d like to dive deeper into this project, click here for the full case study.
Project 3: Demolition At 63 Callowhill Drive
The client for this project asked the Elite team to help remove and dispose of two 21-foot high abandoned incinerator stacks that were left on the roof. As you can imagine, disposing of a 21-foot concrete chimney composed of concrete rings that are each 3-4 feet in diameter on top of a 12 story apartment building roof is no small feat, so the Elite team enlisted the help of Nusens to remove it.
How We Did It:
Nusens brought scaffolding to the roof to reach the top of the incinerator stack. The concrete rings on the stack were removed one at a time and dollied across the roof on a buggy.
Mobilization included the secure setup of scaffolding, protection of the existing roof in advance of demolition activities, and the setup of all life safety lines and other working-at-heights provisions.
The rings were then loaded into heavy-duty poly bags and craned off the roof to a disposal bin at ground level. The roof opening was covered over and we installed insulation and roof membrane over the previous opening for the stack.
The only access point for this roof area was a small access hatch, which made removal of the machinery difficult. Nusens utilized a small modular hoist that was transported in pieces into the building and then assembled in order to lift the scaffolding (a necessary component to ensure the safety of the demolition). The utilization of this method saved the necessity of a crane for the mobilization phase of the job, which saved our client time and money. The position of the crane at ground level needed to be planned out to avoid the need for shoring of the underground parking garage.
