Jobsite Delivery, Storage, and Handling

Building products are sometimes delivered to the jobsite days or weeks before they are finally ready to be installed. While they are on the jobsite, what are some of the “best practices” a contractor should follow with regards to handling these products before use?

Most specifications contain a paragraph or two on delivery, storage, and handling within each product section of a project specification. For roofing, this section is probably similar to other sections involving products with liquids or adhesives associated to their installation. Let's review some of the guidelines.

Jobsite storage recommendations

1. Deliver roofing materials to the project site in original containers with seals unbroken and labeled with manufacturer's name, product brand name and type, date of manufacture, approval or listing agency markings, and directions for storing and mixing with other components. This is important for the verification of products, as well as tracking for sustainability guidelines that may be in place such as on-site recycling.
2. Store liquid materials in their original, undamaged containers in a clean, dry, protected location and within the temperature range required by the roofing system manufacturer. Protect stored liquid material from direct sunlight. This is especially important when the weather is going to be on either end of a product's installation temperature window, such as below freezing.
3. Protect roof insulation materials from physical damage and deterioration caused by sunlight, moisture, soiling, and other sources. Store in a dry location. Comply with the insulation manufacturer's written instructions for handling, storing, and protecting material during installation. Generally, this means cutting open the existing packaging and employing the use of tarps to cover the insulation.
4. Handle and store roofing materials and place equipment in a manner to avoid permanent deflection of deck. Safety and staying alert are always important, especially when staging products before use.

These are just a few guidelines; some manufacturers may require additional handling procedures for winter work, high-wind areas, or high-rise rooftops, as well as projects which involve staging or multiple roof areas. As a specifier, it is always a good idea to let the contractor know of any special handling requirements early on, whether in the specification or at a pre-construction meeting.
