Types of Commercial Roofing

Types of Commercial Roofing

Unlike residential roofing, commercial roofs have many specifications that must be met to ensure the roof’s longevity and durability. This includes how often mechanical contractors must access the roof to service equipment. Commercial roofing also requires consideration of energy efficiency. There are a wide variety of materials available to meet these requirements. Contact your local Roofers Round Rock TX for more information.

Single-Ply Membranes

Single-ply membranes like PVC, EPDM and TPO offer commercial roofing a high-performing defense in the form of a solitary layer of protection. Their shared traits include durability, a long life expectancy and energy efficiency.

These commercial roof systems can be loose-laid, mechanically attached or fully adhered. Loose-laid membranes are a popular choice for retrofit applications and are often installed over an existing commercial roof system. The membrane is then ballasted with heavy, durable gravel for support. This approach minimizes the need for a concrete deck and can help lower the overall cost of the project.

Loose-laid membranes can be installed in three structure types:

PVC membranes are the most commonly used single-ply system, especially for new construction. They are available in a variety of colors and have additives for fire resistance, UV protection and heat welding. PVC is also a highly flexible material that resists changes in climatic conditions.

Modified bitumen (MB) has impressive characteristics. It’s a strong and flexible material that is very durable, with the added benefit of being easy to work with. MB systems can have an expected lifespan of 20 to 30 years.

TPO membranes are a relatively new commercial roofing option that’s quickly becoming a favorite. It’s a single-ply membrane that features a polymer base, a polyester-reinforced fabric center and a thermoplastic polyolefin compounded top ply. TPO is highly resistant to both UV radiation and thermal stress from ozone, as well as being able to withstand dramatic weather changes.

Metal

Metal roofing is a cost-effective option for commercial properties looking to save on energy costs. It has a high insulating value and can help reduce cooling bills by reflecting the sun’s rays. Additionally, it can also resist the spread of fire and protect against wind-blown debris.

While it may cost more than other commercial roofing options, metal has an expected lifespan of 40 to 100 years, depending on the alloy used. The most popular alloy, steel, offers impressive resistance to corrosion if coated with an inorganic coating like galvalume.

Commercial metal roofs are available in a wide range of colors and styles to mimic traditional shingles or tiles. This design choice is ideal for commercial properties that want to preserve the aesthetic of their building while still gaining the advantages of metal.

Standing seam metal roofs are an excellent choice for high-rise buildings with a slope between 1:12 and 2:12. They feature raised ribs that run vertically along the length of the panel, which adds structural strength and helps to prevent water infiltration. These roofs are also thicker than corrugated metal or shingle roofing, which makes them less vulnerable to damage from falling debris or workers’ boots.

Insulated metal panels (IMPs) are one of the latest innovations in the industry. They are a poured-in-place system that combines a metal skin with a polyisocyanurate foam core. This roofing option is growing in popularity, thanks to its ability to withstand extreme weather conditions and achieve a three-hour fire rating.

IMPs are completely recyclable, meaning you won’t have to worry about them clogging landfills. Plus, they are extremely energy efficient. Their light color reflects the sun’s rays, reducing the amount of energy used for heating and cooling in your facility.

Shingles

Though they are often seen on residential roofs, shingles are also a great roofing option for some commercial buildings. With a variety of colors and styles, shingles offer weatherproofing and insulation for steep-sloped roofs at an affordable price point. They are also easier to install than other roofing materials. However, if you’re going to go with this option, make sure your roofing contractor uses premium shingles from a reputable manufacturer such as IKO or GAF. These shingles will offer more longevity and can help you qualify for a higher wind warranty.

If you’re looking for a more aesthetically pleasing commercial roof, architectural and designer asphalt shingles are the way to go. These shingles are thicker than 3-tab shingles and offer more durability and an upgraded aesthetic that can last 25-35 years. They are also available in a range of colors and can even replicate the look of more expensive materials such as slate or wood shakes. These shingles can add more curb appeal to your commercial property and increase its value as well.

Commercial shingle roofs can be a good choice for many types of businesses and organizations, but if you plan to vent oils, greases, fats, and other flammable substances onto your roof, this type of roofing isn’t recommended. PVC is a better material for this type of commercial roof, as it has a high fire rating and will not break down or become brittle when exposed to flammable materials.

If you are considering a shingle roof, be sure to speak with our roofing experts to learn more about your options and how each will affect the lifespan of your commercial roof. Our experienced team will use our decades of expertise to guide you through the process and ensure that you’re making the right choice for your business.

Low-Sloped Roofs

Low-sloped roofs with a slope of 3:12″ or less are the most common commercial roofing system. These flat roofs are typically referred to as membrane roof systems and can be made of various materials including EPDM, PVC, or TPO. All are typically rolled out in sheets and adhered to the roof deck. These are the most popular choices for commercial roofs because they are durable, affordable and easy to maintain. They also provide good energy efficiency since they are able to reflect the sun’s heat rather than absorbing it.

Like steep-sloped roofs, they need to be inspected for leaks and other damage. Commercial roofs should be inspected at least once a year. The inspection should include a visual check of the surface of the roof as well as checking for any pooling water or debris and an examination of the decking. More extensive or comprehensive inspections of flat roofs are often recommended and can be performed by professional roofing contractors.

One of the oldest types of flat or low-sloped roofing is built-up roof (BUR) – an asphalt, coal-tar pitch or asphalt emulsion product with multiple layers of bitumen hot or cold applied in between layers of reinforcing plies, mats, felts or other saturated or coated base sheets. BUR offers a cost effective choice for low-sloped roofs and it is known for its superior fire resistance.

Other common low-sloped roof systems include ethylene propylene diene monomer (EPDM), or thermoplastic olefin rubber and vapor barrier roofing which are durable, inexpensive and easy to maintain. These are commonly used on hospitals, warehouses, shopping malls and grocery stores. They are also available with warranties of up to 20 years by manufacturers such as GAF and Johns Manville.

High-Sloped Roofs

Unlike flat roofs, sloped or pitched roofs have a slight pitch to them, which allows rain and snow to easily shed off the roof. This is a great feature because commercial buildings often have a lot of equipment like AC units on the roof, and they need to shed water quickly.

A roof’s pitch can also have a significant impact on what type of roofing materials work best with it. For instance, a steep roof will require an adequate gutter system to effectively shed rain and snow. Additionally, a steep roof needs to be properly maintained and inspected to ensure the proper drainage of water.

Steep-slope roofs have a familiar and classic look that complements a wide variety of structures. They also tend to be more energy efficient, as the slight pitch helps prevent pooling of water and reduces heat loss. However, they’re not without their downsides. For instance, steep-sloped roofs can be more difficult to maintain than flat or low-sloped roofs, and they’re at a higher risk of collapse if not properly installed and maintained.

While many people choose their roofing materials based on aesthetics, the climate of their region should have an important influence on what they select. Extreme temperatures can accelerate the deterioration of certain roofing materials, and ice dams can form when melting snow is blocked from draining. Consequently, roof coverings that can withstand harsh weather conditions are more likely to be a good fit for Colorado building owners.

Regardless of the material chosen, a commercial roof is an important investment. As a result, it’s essential to consult with an experienced professional roofing contractor to evaluate the current condition of your roof and determine what type of material would be most suitable for it.

The Importance of Asbestos Removal

If you suspect asbestos in a house, have a certified Asbestos Removal Perth inspector come to conduct a home inspection and test materials. Once the material is identified, you can take steps to have it removed. During reduction, the work area is enclosed, and contaminated air is pumped out through HEPA filters and exhaust ducts. HEPA filters must also be used on all tools and clothing to prevent the spread of dust.

Rebar

Asbestos was once used in many building materials, including wall panels, floor tiles, insulation, and roof shingles. These products were used in both commercial and residential construction. Despite being banned in the 1970s, asbestos remains in older buildings and can still cause health problems. If disturbed, it releases harmful fibers into the air which, if inhaled, can lead to lung diseases such as asbestosis and mesothelioma.

Often used to strengthen concrete constructions, rebar is the most common type of steel bar you’ll see on any major road or in building foundations. It’s important to make sure that rebar is not rusted or corroded when you buy it because this could pose a safety risk. It should also be cut to the correct length before use because a longer piece of rebar may not have enough strength.

Rebar is usually made from carbon steel and can be galvanized or coated in epoxy to increase its corrosion resistance. This is particularly important if it will be exposed to chemicals or salt water. Stainless steel rebar is also available but it’s much more expensive.

When rebar is used in concrete, it’s placed at regular intervals and helps to strengthen the material by increasing its compression and tensile strengths. It also helps prevent the formation and expansion of cracks that might damage a structure.

Most rebar is produced in North America using an EAF process, or electric arc furnace, which turns scrap steel into molten metal. From there, it’s poured into a casting and cut to the desired length.

Before asbestos removal is done, make sure your contractor has a written work plan and cleanup schedule, as well as federal, state and local regulations which they must follow (including notification requirements, disposal, handling and transportation procedures). It’s also wise to get proof that the contractor has liability insurance that covers the cost of any workers’ compensation claims. In addition, the contractor should use plastic sheeting to seal off the work area from the rest of your home and turn off any heating and cooling systems during the job.

Insulation

Many homes built before 1980 contain asbestos insulation. Asbestos is made up of fibrous bundles that can be woven like fabric. It has many useful properties, such as being fire-resistant, flexible, and resistant to chemicals. It also offers soundproofing and thermal energy. It can be found in flooring, wall tile, and insulation. However, if this material becomes damaged or disturbed it can release harmful asbestos fibers. This is why it is important to monitor the condition of this type of material and to hire a certified professional when necessary.

There are several things to look for when hiring a professional to remove asbestos. It is important to ensure that they have completed federally-approved training and have a current license to work in this field. They should also be able to provide you with a list of references from past clients. In addition, homeowners should consider hiring a monitoring firm that does not have any financial ties with the abatement contractor. This will help to ensure that the abatement is done correctly and does not increase exposure to harmful asbestos.

It is also important to know that not all asbestos materials require removal. If the asbestos is in good shape and will not be disturbed, it may be safer to repair it instead of removing it completely. In fact, asbestos professionals should always advise their clients as to whether repair or removal is the safest option for their home.

During the Industrial Revolution, asbestos was used in a number of different products such as floor tiles and textiles. It was then incorporated into products such as boilers and high-temperature pipes. It was eventually marketed as an effective insulator, and it was widely used throughout the United States in buildings, ships, and steam engines.

In order to properly perform an asbestos abatement, a qualified and licensed asbestos professional should use a special vacuum cleaner with HEPA (high efficiency particulate air) filtering. They should also wet mop the work area to minimize the spread of asbestos. All equipment and clothing that contains asbestos should be placed in sealed, leakproof plastic bags. The work area should be visually inspected to ensure that all asbestos material has been removed.

Floor Tiles

Floor tiles made with asbestos were once a very common flooring material and they are still sometimes present in older homes. However, because of the negative health effects that have been linked to asbestos, any deteriorated or contaminated flooring materials must be removed. This is especially true for older floor tiles.

The first step in removing asbestos tile is to ensure that the work area is completely sealed off to prevent contaminating other areas of the building. Then, a comprehensive decontamination process must be carried out to remove any remaining asbestos and also to dispose of it in accordance with local regulations.

It is highly recommended that you hire a professional to remove your asbestos flooring. Asbestos professionals are trained to know the best way to handle these dangerous materials, and they will be able to ensure that any contaminated floor tile is safely removed without any ill-effects on other parts of the property.

While it is possible for homeowners to remove some asbestos floor tile themselves, this is not a good idea as it can be very dangerous and requires a lot of care and attention. Inhaling even a small amount of toxic asbestos fibres can have long-term adverse health effects such as lung cancer and mesothelioma.

The only definitive way to determine whether your old floor tiles contain asbestos is to have them tested by a laboratory. A number of companies offer asbestos test kits that allow you to take a sample from your tiles and then mail it off for testing. These kits are usually available for purchase in DIY stores and online, but it is much better to consult a certified asbestos remediation expert than to use a test kit on your own.

If your old floor tiles do contain asbestos, you should not sand or cut them as this will release airborne fibres into the environment. It is possible to install new flooring over the top of old asbestos floor tiles, but this is only an option if the tiles are in good condition and not damaged.

Wall Tiles

If you’re doing some remodeling and suspect your wall tiles contain asbestos, it’s a good idea to have them tested. The safest way to do this is to call a professional who has testing equipment available on site, or can send them away for lab testing. This service can cost a bit more, but it’s far better than working with an unknown substance that may pose a threat to your health.

Most wall tiles do not contain asbestos and if they are in good condition, they’re unlikely to pose any kind of a risk. The problem comes when they are disturbed and the fibers become airborne. This is a potential danger with any type of renovation that requires tearing down or sawing through floor or wall tiles. If you’re planning a major renovation project, it’s a good idea to get your floor and wall tiles tested and possibly encapsulated by professionals who are familiar with handling toxic materials.

Many homeowners understandably freak out when they discover that their old floor tile contains asbestos. The best thing to do is to find a licensed asbestos abatement company who will test the material and make recommendations on how to proceed.

When performing your own asbestos removal, it’s important to take the proper precautions. Set up a work area with plastic sheets to isolate the area, cover all doors and windows with flaps, turn off heating and ventilation systems and use a respirator with a high efficiency particulate air (HEPA) filter. This will help keep microscopic asbestos particles from spreading throughout your house and putting everyone at risk.

Asbestos-containing tile and flooring are a common discovery in older homes and buildings, and while it is scary to think they could be dangerous, they are typically not a health hazard unless the tile and adhesives are damaged or dislodged. If you are worried about old floor or ceiling tiles, it’s a good idea to call in an asbestos remediation company who will perform the necessary testing and follow strict procedures to safely handle these materials. They will also know how to dispose of them correctly and avoid contaminating the surrounding areas.
