It is no simple task to find the right replacement for an aging roof – or to determine the appropriate option for a new structure. Just down the lane, the best roofing solution for one building could be the wrong choice for another. That is because, even though they closely resemble each other no two buildings are exactly alike. But how do you pick a new roof, with all the marketplace options? Before you select the roof, the roofing contractor or the producer, you can begin by asking a series of questions.

1. What is the mission statement of this building?
The first thing to answer before calls are made to roofing contractors or suppliers is the mission statement of the organization when it applies to the house.
You want to be sure that the roofing systems you choose deliver the value you intend, whether you are designing new facilities or maintaining existing assets. The building itself determines the required design of the roofing system more frequently than not.
You need to know as much as possible about the building and its future. Will the business plan for the next 10 to 20 years to retain this building as part of its real estate assets? In the near future, are there any proposals to extend it or to change its use? What are the existing and future occupancy, insulation specifications, aesthetic priorities and even the rooftop equipment maintenance schedules?
This and other concerns with the mission statement can help shape reactions to roofing forms to be taken into account and how much of the capital budget is actually needed for the job.
Begin your questions with the issue of what the building will be used for. You would only need a simple roof if it’s a spec home. But if the building has a special usage, such as an airline reservation center with machines in it then the roofing choices are very different in the calculations.
For starters, the data center must never spring a rooftop leak as more businesses shift into working 24 hours daily, seven days a week to please global consumers. Generally, water on computing devices spells tragedy.
For cooling-dominated climates, there is a special collection of considerations. Is the roof leading to savings in air conditioning and solving other primary issues? Is it part of a complete program for energy? There is a growing question about islands in urban sun. For a variety of factors, reflective white roofs have been of concern in those areas. They keep the building cooler, reduce the cost of air conditioning and therefore decrease the environment’s heat-loading.
2. What physical and other factors affect the selection of the roofing system?
After defining a facility’s priorities and purpose, it is time to determine the building itself. You must begin by looking at the site of the building and the characteristics of its surrounding environment. Building codes, environmental patterns, topography – and the path facing the building – need to be studied.
The building’s physical aspects are also crucial: scale, form, style, height and age.
The building materials used to build the facilities and the placement of HVAC and fire safety equipment must also be looked at, particularly if one or both of these are partially or completely housed on the rooftop.
You ought to list the characteristics of the roof area itself when it comes to roof repair. The roof’s height, form, slope, deck construction, edge detailing, protrusions, access to the rooftop and current roofing system are better detailed. You need to figure out along with this simple detail, why the original roof is no longer adequate.
3. What choices are available for flexible-membrane roofing?
Three main types of membranes are listed by SPRI, the organization that represents sheet membrane and product suppliers to the commercial roofing industry: thermosets, thermoplastics, and modified bitumens.
Thermoset membranes are composed of polymers made of rubber. EPDM, also referred to as “rubber roofing,” is the most common. These membranes are better suited to avoid the potentially harmful effects of sunlight and the common chemicals present on roofs. On the rooftop, they are readily identified. Just look at those seams. Thermoset membranes require liquid or tape adhesives at the overlaps to form a waterproof seal.
Plastic polymers are the foundation of thermoplastic membranes. PVC, which is made versatile by the addition of plasticizers, is the most general. Thermoplastic membranes have seams that using heat welding, are most frequently formed. To provide improved strength and dimensional flexibility, most thermoplastic membranes are manufactured with a reinforcing sheet, typically polyester or fiberglass.
As a thermoplastic, Hypalon thermoplastic starts, but cures to become a thermoset with time. Hypalon fabrics are like most thermoplastics, heat sealed at the seams.
Thermoplastic polyolefin (TPO), which incorporates the properties of EPDM with PVC, is another thermoplastic hybrid. After exposure to the elements, TPO membranes do not heal and remain hot-air weldable throughout their service life. Most TPO membranes are reinforced with polyester, fiberglass or a mixture of the two, although there are available non-reinforced TPO membranes.
In some of the conventional installation methods used in built-up roofing, modified bitumen membranes combine the formulating and prefabrication benefits of flexible-membrane roofing. Modified bitumen sheets are factory-made, consisting of asphalt that is modified for improved durability with a rubber or synthetic polymer, and combined with a reinforcement for additional strength and stability.
