10 Questions To Ask Before You Choose A Roof

Choosing the right substitute for the aged roof - or even identifying the very best choice for a brand new construction - is no easy task. The perfect roofing solution for one building might be the worst alternative for another down the street. That's because no two buildings are exactly alike, even though they closely resemble each other. So how can you opt for a new roof, given all of the options in the market? It is possible to start by asking a series of questions, until you choose the roofing, the roofing contractor or producer.

1. What is this construction's mission statement?

Ahead of calls are designed to roof contractors or manufacturers, the very first item to tackle is the organization's mission statement as it relates to the building.

Whether you're building new installations or managing existing possessions, you want to be assured that the roofing systems you select deliver the performance you expect. More frequently than not, the building itself dictates the suitable roofing procedure specification.

You will need to know as much about the building and its potential as possible. Does the business plan to keep this building as part of its real estate resources for the next 10 to 20 years? Are there any plans to expand in the not too distant future, or to change its usage? What are the current and future occupancy, insulation requirements, aesthetic priorities as well as the maintenance programs for rooftop equipment?

These along with other mission statement issues can help shape replies to types of roof to think about and the amount of the funds budget is truly required for the job.

Start your questions together with what exactly is the construction going to be utilized for. When it's a spec construction, maybe you simply need a fundamental roof. However if the center has a unique use, such as an airline reservation center with computers inside, then your considerations for roofing options are very different.

For instance, as more firms move toward working 24 hours daily, seven days per week to meet global customers, the data centre must never spring up a rooftop leak. Water on pc systems normally spells disaster.

A unique set of concerns arise because of cooling-dominated climates. Does the roof contribute to air conditioning savings and address other key issues? Can it be part of a entire energy plan? There is an increasing concern about urban heat islands. White roofs have been of interest in those places for a few factors. They keep the building cooler, reduce air conditioning costs and minimize the heat-loading of their surrounding environment.

2. What physical and other elements help determine the roofing system selection?

After identifying the aims and mission of a center, it is time to evaluate the building itself. You want to begin by taking a look at the building's place as well as the attributes of its surrounding location. You will need to examine building rules, weather trends, topography - much how the building faces.

The physical characteristics of the building will also be crucial: size, shape, layout , height and age. In addition, you ought to look at the building materials used to construct the centre and the place of HVAC and fire protection equipment, especially if either or both of these are partly or totally housed to the rooftop.

When it comes to roof replacement, you want to list the attributes of the roof area itself. It's best to detail the roof size, shape, slope, deck structure, edge detailing, protrusions, rooftop accessibility and existing roofing system. In addition to this simple info, you will need to learn why the roof is not adequate.

3. What flexible-membrane roof choices are available?

SPRI, the association that reflects sheet membrane and component suppliers to the commercial roofing business, identifies three important sorts of membranes: thermosets, thermoplastics and modified bitumens.

Thermoset membranes are produced from rubber polymers. The most usual is EPDM, often known as"rubber roofing." These membranes are well suited to resist the potentially harmful effects of sun and the most common compounds found on roofs. They are easily identified on the rooftop. Just look at the seams. Thermoset membranes require tape or liquid adhesives to form a watertight seal at the overlaps. Thermoplastic membranes are based on vinyl polymers. The most frequent is PVC, which can be made elastic by adding plasticizers. Thermoplastic membranes have stitches that are most frequently formed using welding. Most thermoplastic membranes are produced with a reinforcement coating, usually polyester or fiberglass to offer greater durability and dimensional stability.

Hypalon thermoplastic begins as a thermoplastic, however, cures over time to become a thermoset. As with other thermoplastics, Hypalon substances are heat sealed in the seams.

Another thermoplastic hybrid vehicle is thermoplastic polyolefin (TPO), which combines the features of EPDM and PVC. TPO membranes do not heal after exposure to the components and stay hot-air weldable throughout their service life. Many TPO membranes are reinforced with fiberglass, polyester or a combination of both, but unreinforced TPO membranes are readily available.

Modified bitumen membranes comprise the formula and prefabrication benefits of flexible-membrane roof with a number of the conventional installation techniques used in built-up roofing. Modified bitumen sheets are factory-fabricated, made up of asphalt that's modified using a rubber or plastic polymer for greater flexibility, and combined with a psychologist for extra strength and stability.

4. Which type of attachment and tissue system are greatest for your construction?

Many things determine the best system for a specific building. For most buildings, there are quite a few alternatives and benefits which will need to be weighed against the facility's mission statement. The choice should not be made just on the basis of cost. Other significant factors for membranes are building elevation, wind exposure, expected roof traffic and aesthetics.

The attachment method also is based upon the specific building's characteristics. In case the roof deck is able to defy the fat, then a ballasted roof may be the best choice. However , if the slope of the roof is higher than 2 inches every foot, this system might not be suitable. There are other limitations on ballasted systems, for example roof height, proximity to shorelines and other large wind zones, and the access to ballast. A wood or steel deck that easily accepts fasteners makes a fantastic substrate for a mechanically fastened membrane. These programs are made to deliver the necessary resistance to known breeze forces and aren't subject to slope limitations.

Another option is the fully trapped system, in which the membrane is attached to the prepared substrate utilizing a specified adhesive. Depending upon the veins, the adhesive may be solvent- or asphalt or masonry. The finished surface of a stuck roof is so smooth.

For all those worried about building aesthetics, colored membranes can make an appealing contribution to the building's appearance.

5. Does all roofing material delivered to the work website bear the UL label?

Otherwise, define that it needs to. Here is the only way you're able to guarantee that the roofing materials installed on your roof would be the exact materials tested by Underwriter's Laboratories. Also, be certain the roof meeting you buy or set up, which comprises the insulation, is UL-classified and -tagged. Using an insulation besides that which was analyzed with the roof membrane could void the UL classification. If the UL Building Materials Directory doesn't record the roof system you are sold, insist on confirmation of this classification in the form of a photocopy of this UL's letter of approval.

Ensure the product that you are receiving is the true product that was analyzed. You don't need something that is similar but not equivalent. Look for the label at the work site and be certain all components of this system were tested together. You would like the membrane tested with the insulating material which you are using in your construction.

6. Does the system need a wind uplift rating?

Wind uplift damage may be extensive and costly. Accepted as a market standard, American Society of Civil Engineers Standard 7-95,"Minimum Design Loads for Buildings and Other Structures," may be employed to determine the end zone of the building. Wind uplift testing, such as that done in Factory Mutual or Underwriters Laboratories, can be utilized to ascertain that the chosen roof system meets or surpasses the local wind reduction requirements.

7. How much can the completed system add to the dead weight of the roof structure?

In deciding on any reroofing option, the facility executive needs to be conscious of the load-bearing capacity of the roof deck to make sure the perfect flexible-membrane choice is chosen. In new construction, economies in steel steel can often be accomplished by installing a few of the lighter flexible-membrane systems.

A ballasted thermoplastic or EPDM roof may require in excess of 1,000 lbs per 100 square foot, whereas a mechanically attached or fully adhered thermoset or thermoplastic membrane weighs 33 pounds per 100 square feet. A lighter system often lets you reroof directly over your existing roof, while the thicker ones could ask you to rip off the old roof and start anew. But weight is but 1 factor in the collection of a roofing membrane and attachment system. A ballasted roof may be the ideal choice for a given facility. Facility executives must guarantee that all relevant considerations, such as weight, are taken into consideration from the decision-making process.

8. What are the expertise and financial strengths of the roofing contractor you are thinking of?

Roofing contractors will need to be chosen with wonderful care. The debut of new roof materials and application techniques over the past 10 years has led to a lot of changes.

Ask the contractor if his or her business is a member of a neighborhood, state, regional or national business association. Contractors involved in professional institutions generally are much better informed on the latest developments and issues of their business.

Insist the contractor provide you with copies of insurance certificates that verify workers' compensation and general liability coverages. Check that these coverages are in effect for the duration of your roofing job. If the contractor isn't properly insured, your employer, since the property owner, may be liable for accidents occurring in the property. Also check your state's licensing conditions and find out whether the contractor is secured by a surety company.

The setup of different roofing systems varies substantially. Education and training will be the most essential components from the installation of roofing systems. Be certain the roofing contractor you select has had comprehensive and ongoing training about the machine being installed.

One rule of thumb would be to discover if the builder has installed at least 100,000 square feet of the system you want in the previous 18 months. Also, ensure the contractor is approved by the producer to set up that system.

The standard of workmanship is vital to great roof functionality. The National Roofing Contractors Association provides a professional roofing choice guide. Furthermore, many producers have approved builder programs with particular qualifications which roofers must finish before acceptance.

9. What's warranted and by whom?

There are two fundamental categories of roof warranties. The contractor's warranty usually covers workmanship. The manufacturer's warranty covers the stuff, however many insure added products. Even if the manufacturer's warranty is broad, it will not fully protect you if the roof is improperly installed.

Carefully read and understand some roof guarantee offered and watch for provisions that would void it. As an instance, it's nearly impossible to avoid all ponded water. Ponded water can be caused by a clogged roof drain or deflection of the roof deck between the support columns. Good roof maintenance will help ensure the guarantee remains valid. Be conscious of warranty language that voids the warranty.

Most specialist roofing contractors will offer periodic maintenance inspections throughout the year. These reviews help to ensure your project complies with all the criteria specified in the warranty. A normal maintenance program is made up of comprehensive visual examination of the roof program, flashing, insulation and related components to identify any potential trouble areas.

More important than the warranty, however, is getting the right flexible-membrane roof on the building in the first location. If the roof is correctly installed and designed to meet your center's requirements, building codes and geographic factors, and the warranty covers those requirements, you likely will be appreciating the benefits of a flexible-membrane roof many years after the initial warranty expires.

10. After the roofing is set up, what afterwards educational and service programs are available for the facilities management team?

Seminars provided by roofing business associations such as SPRI and producers may be invaluable methods for the building's roofing group to expand their understanding of commercial roof system forms, installation processes and maintenance considerations. Specific courses are readily available to assist building owners and facilities managers find out more about various roofing systems, materials and components; insulation and accessory products; components of roof layout; contractor choice; warranties and maintenance considerations.
