Choosing the most versatile shelter roofing supply nashville tn replacement for an aged roof
Finding the best shelter roofing supply nashville tn replacement for an old roof – or identifying the best choice for a new building – is no easy task.

So how do you choose a new roof, given all the choices in the marketplace? You can start by asking a series of questions, before you choose the roof, the shelter roofing supply nashville tn or the manufacturer.
1. What is this building’s mission statement?
Before calls are made to shelter roofing supply nashville tn, the first item to address is the company’s mission statement as it relates to the building.
More often than not, the building itself dictates the appropriate roofing system specification.
Does the shelter roofing supply nashville tnplan to keep this building as part of its real estate assets for the next 10 to 20 years? Are there any plans to expand it in the near future, or to change its use? What are its current and future occupancy, insulation requirements, aesthetic priorities and even the maintenance schedules for rooftop equipment?
But, if the facility has a special use, such as an airline reservation center with computers in it, then your considerations for roofing options are quite different.
For example, as more shelter roofing supply nashville tnmove toward operating 24 hours daily, seven days a week to satisfy global customers, the data center must never spring a rooftop leak. Water on computer systems generally spells disaster.
A special set of concerns arise for cooling-dominated climates. Does the shelter roofing supply nashville tn contribute to air conditioning savings and address other key issues? Is it part of a total energy program? There is a growing concern about urban heat islands. Reflective, white roofs have become of interest in those areas for a few reasons. They keep the building cooler, reduce air conditioning costs and also minimize the heat-loading of the surrounding environment.
2. What physical and other elements influence the shelter roofing supply nashville tnsystem selection?
You need to begin by looking at the building’s location and the attributes of its surrounding area.

3. What flexible-membrane shelter roofing supply nashville tn options are available?
Thermoplastic membranes have seams that are most commonly formed using heat welding.
TPO membranes do not cure after exposure to the elements and remain hot-air weldable throughout their service life.
Modified bitumen membranes incorporate the formulation and prefabrication advantages of flexible-membrane shelter roofing supply nashville tn with some of the traditional installation techniques used in built-up shelter roofing supply nashville tn. Modified bitumen sheets are factory-fabricated, composed of asphalt which is modified with a rubber or plastic polymer for increased flexibility, and combined with a reinforcement for added strength and stability.
4. Which type of membrane and attachment system are best for the building?
Many factors determine the best system for a particular building. For most buildings, there are a number of options and advantages that need to be weighed against the facility’s mission statement. The decision should not be made only on the basis of cost. Other important considerations for membranes are building height, wind exposure, anticipated roof traffic and aesthetics.
If the roof deck is able to withstand the weight, a ballasted roof may be the best option.
For those concerned with building aesthetics, colored membranes can make an attractive contribution to the building’s appearance.
5. Does all roofing material delivered to the job site bear the UL label?
Additionally, be sure that the roof assembly you buy or specify, which includes the insulation, is UL-classified and -labeled.

Look for the label at the job site and make sure all components of the system were tested together. You want the membrane tested with the insulation that you are using on your building.
6. Does the system require a wind uplift rating?
Wind uplift damage can be extensive and expensive. Accepted as an industry standard, American Society of Civil Engineers Standard 7-95, “Minimum Design Loads for Buildings and Other Structures,” can be used to determine the wind zone of the building. Wind uplift testing, such as that performed at Factory Mutual or Underwriters Laboratories, can be used to determine that the selected roof system meets or exceeds the local wind uplift requirements.
7. How much does the completed system add to the dead load weight of the shelter roofing supply nashville tn structure?
In choosing any shelter roofing supply nashville tn option, the facility executive should be aware of the load-bearing capacity of the roof deck to make sure the right flexible-membrane option is chosen. In new shelter roofing supply nashville tn construction, savings in structural steel can often be achieved by installing one of the lighter flexible-membrane systems.
A ballasted thermoplastic or EPDM roof may require in excess of 1,000 pounds per 100 square feet, while a mechanically attached or fully adhered thermoset or thermoplastic membrane weighs 33 pounds per 100 square feet.
