If mechanical fasteners are going to be used to attach insulation or a single-ply membrane to the deck, will the deck provide adequate pullout resistance?

Since the foundation of any roof system is the roof deck, this column will focus on several of the roof deck systems that a building manager might encounter when contemplating roof work. N roof deck provides a long span structural member. That is because the large structures tend to span more distance and carry more weight in equipment on the roof, including air conditioning, air circulation pumps, etc. Since the equipment must be serviced frequently, the roof deck has to be able to take the weight of maintenance personnel on the roof on a regular basis, as well as everything the elements can throw at it. There should be enough space between the threshold and the deck surface.

If your roof experiences one or more of the problems above, there is a good chance that a roof replacement is an answer. For many home-owners, the decision on whether to repair of replace a roof on an older property can be a tough one. At 3" deep, N roof decking meets specifications for structures where the supporting members need to be placed as far apart as possible.

While all these attributes may have been addressed by the building designer on the drawing board, the building manager needs to know what is overhead and what its current condition is. There are some things about roofing that a homeowner must also know though.

Things may have changed over time. FIG 5) At one time in the past, it was common practice to remove deteriorated gypsum decking and to replace it with metal decking and rigid roof insulation.

Measure the outside perimeter of the roof to calculate the drip edge required. It is critical that the galvanized wire mesh be attached to the existing wire at the perimeter of the patch for safety reasons. New form boards, galvanized wire mesh and poured gypsum should be used.

In this case, a contractor should be called in for a repair. To do that effectively, homeowners need to understand some of the tell-tale signs that indicate that a roof is in need of repair and maintenance. Though many minor repairs can be done by the homeowners themselves, larger projects should always be left to a skilled professional.
