Keeping your reroofing project on track

If you are considering reroofing a building that is in use, you are probably concerned about maintaining "business as usual" while the project is underway.

The success of any project depends, in part, on preparation and planning in the early stages. By being aware of your options, communicating effectively with your roofing contractor and making the correct decisions up front, you can help ensure a successful outcome and save yourself time, money and frustration.

Let’s look at the various stages of a reroofing project and the impact each can have on your operations.

Selecting a roofing contractor

"Roofing Contractors" is the fifth largest group listed in the Yellow Pages. Many of these companies claim to have expertise in commercial and industrial work, yet only a small number really do. One way to find the most qualified roofing candidates is to ask your current contractor to name his best competitors. If your contractor is "worth his salt," he won’t feel threatened by the question and will be confident in bidding against them.

If you are not satisfied with your present contractor, then you will need to identify good contractors by another means. One good way is to ask other plant owners and managers in your area about their contractor and satisfaction level.

The next step in the pre-qualification process is to ask your "short listed" contractors for the following information:

• Number of years in business. This will help determine the contractor’s longevity and financial stability, as well as the company’s history of meeting its obligations.
• Customer references. Be certain to check them.
• Personnel and training. Does the contractor have experienced, well-trained roofi ng professionals who know and will implement proper installation and safety procedures?
• Insurance coverage. Is it adequate? At the same time ask about their Experience Modification Rating (EMR). The rating is based on a number of factors, including the contractor’s safety record and worker compensation claims. An EMR rating more than one is unacceptable. The lower the number, the tighter their ship.
• Facilities and equipment. Are the contractor’s facilities and equipment capable of meeting the special requirements of your roofing project and completing it in a timely manner?
• Services offered and areas of expertise.

When you have narrowed the list to two or three qualified contractors, ask them to submit a detailed proposal for your project. Then sit down with each contractor and go over it. Don’t hesitate to ask questions about the line items, especially personnel, procedures, materials, workmanship, pricing and scheduling. Good contractors know that educated customers make the best buying decisions, so they will be pleased to take the time to explain their services to you.

Planning

First, establish an internal project team consisting of those affected by the areas being reroofed.Without question, someone from the safety department should be a key player.

Prior to scheduling or establishing procedures, the roofing contractor should ask you about your needs, especially relative to your occupancy considerations. Make sure your contractor is taking appropriate steps to protect sensitive areas and activities within your facility. An example that comes to mind is a recent project that required reconstructing a roof over an electrical substation. Extraordinary care had to be taken to prevent dirt, debris and moisture trapped in existing insulation from dropping into the space below.

You also want to protect the outside area surrounding your facility. If you are in a congested location, you will need procedures to protect the safety of passers-by. In some cases, scaffolding will be erected on the exterior to serve as a walkway to protect pedestrains during hoisting activites. Other temporary protection like plastic sheathing on the interior can minimize falling debris and dust from beams and purlins.

Reroofing often requires a combination of activities. Demolition work to remove the old roofing materials is by far the most disruptive phase of the reroofing process. Heavy equipment and men working overhead cause noise and vibrations. If you need to replace deteriorated decking, it is often a good idea to cordon off the area underneath and restrict access. If this is not possible due to ongoing production be sure the plant occupants understand the nature and duration of the work. Effective communication among all parties is important.

The existing roof may contain asbestos materials. When present, asbestos must be removed and disposed of in accordance with current federal, state and local regulations. Be sure your contractor is certified by the appropriate regulatory agencies to perform this work. In most cases, it is neither difficult nor expensive; however, there should be a paper trail for the protection of everyone concerned. Under the law the plant owner has cradle-to-grave responsibility for asbestos.
