Roofing services are an essential component of the building process. Built-up roofing systems are a popular choice for lower slopes because they can be installed and handled easily and quickly using standard hand tools and fabricating equipment. Commercial built-up roofing systems are built from hot asphalt or cold process built-up roofs which have been the standard method of built-up commercial roof coverings for decades.
Commercial Roofing functions
These are designed to control or shelter all types of buildings. They are designed to provide the necessary weather protection and fire protection. The properties of heat insulation, sound insulation, waterproofing and corrosion resistance are also required for commercial roofs.
It is essential to choose a roofing contractor who has expertise and knowledge of the products and services offered as well as professional experience. This not only ensures that your project will be completed on time and within budget, but it also gives you the satisfaction of knowing that the job was done properly and with the highest quality.
Professional roofing contractors will not only provide the appropriate commercial roof but they will also ensure that all necessary trades such as plumbers, electricians, and laborers are hired to complete the job on time and within budget.
Why is Commercial Roofing necessary?
Commercial built-up roof systems are a pan of the essential building envelope. Commercial roofs range from high-pitched to flat and provide complete weather protection while supporting required design loads. The roof system must have the capacity to protect the interior of the structure from environmental factors such as water leaks, heat, cold, wind damage, and so on. The longevity of commercial roofs depends upon the quality of their design and construction.
A poorly designed or constructed roof can lead to:
1) Water infiltration and leaks
2) Excessive heat gain/loss
3) Drafts and associated energy losses
4) Moisture and mold growth
5) Damage to the building envelope and its contents.
Commercial built-up roof systems provide many benefits:
They are watertight and provide excellent hurricane protection. They protect the building against penetration of cold air and snow loads, as well as high winds. A good commercial roof system reduces the risk of moisture penetration and helps keep interior conditions comfortable year-round. It can contribute to better indoor air quality and help protect against fire.
Commercial roofs are a critical part of the building envelope and should be designed, installed, and maintained using the latest techniques and technologies. To ensure the best protection for your business, always work with a qualified roofing contractor who has experience installing commercial built-up roofs.
A well-designed and properly installed commercial roof can provide many years of reliable service. But like any other structure, it will eventually need to be replaced. When the time comes, make sure you work with a qualified contractor who can provide a competitive quote for a new roof system that meets your needs and budget.
What are the Best Commercial Roofing Materials?
Commercial roofs can be made from a variety of non-metallic and metallic materials. Non-metallic for commercial roofing: Commercial roofing shingles can be constructed from:
Polymer cement: This is one of the most common types of shingle and is made from a blend of Portland cement, sand, and polymer modifiers.
Asphalt: This is one of the most common types of roofing in North America and is made from an asphaltic material that contains a mineral filler such as slag or volcanic glass.
Glass fiber reinforced asphalt (GFRAS): This type of asphalt shingle is made with a glass fiber mat that is sandwiched between two asphalt layers.
Stone-coated steel: This type of roofing has a thick layer of ceramic-coated steel that is bonded to a lightweight aluminum substrate. The steel provides durability and the ceramic coating offers protection from the sun’s UV rays.
Metal roofing: Metal roofs are made from a variety of metals, including copper, aluminum, galvanized steel, and stainless steel.
How is Commercial Roofing built?
Commercial built-up roofs are made by applying bitumen or another liquid adhesive, using built-up roofing applicators. The built-up roofing system is typically an assembly of multiple layers of reinforcing mat, with the number of plies depending on the type of built-up roof. For stone-coated steel built-up systems three plies are typically used. For built-up roofing with a thermoplastic polymer modifier, two plies are typically used. Built-up roofing requires skilled applicators, and the contractor should be experienced in commercial built-up roofs to ensure that the work is performed properly.
Today’s commercial built-up roofing systems are built using rubberized asphalt products, with typical choices being either a smooth or granulated surface. The membrane is composed of multiple plies of asphalt-saturated felt, with each ply weighing approximately 36 pounds per 100 square feet.
The top ply is a weathering layer that contains a built-in surfactant and UV inhibitors to resist deterioration from the sun’s rays. The next three plies are composed of fiberglass, and the bottom ply is a polyester mat that helps to distribute the load.
The roofing system should be installed using approved adhesive and seaming tapes, which are then covered with a layer of hot asphalt built up to approximately 2 inches thick. A mineral surface aggregate is then broadcast over the top to provide weather protection.
The built-up roofing system is one of the most durable types of commercial built-up roofs. It usually has an expected life span of 20 years or more, depending on climatic conditions and building usage.
Types of Commercial Roofing
There are three types of commercial roofs that are chosen depending on the climate, usage, and the structural strength of the building. They are pitched roofs, flat roofs, and domes.
Pitched roofs are one of the most common commercial roofing types and can be made from asphalt or metal. They have at least one vertical slope, which allows the drainage of rainwater easily. Pitched roofs also allow more snow to accumulate than other types of roofs, so they need snow guards that help remove it before it becomes too heavy.
Flat roofs are not very common in commercial buildings due to their vulnerability to damage and leaks, and the fact that most construction building codes require a minimum angle of pitch for all types of roofs. Flat roofs can be constructed from metal sheets or membranes such as EPDM rubber. They are used for small structures with lightweight loads such as warehouses and garages.
Domes are very strong roofs that can span large areas, and they are often used for sports stadiums, airports, and other large buildings. They are made from metal or reinforced polymer and can be either flat or curved. Curved domes offer the most resistance to wind loads.
Nonetheless, Commercial built-up roofs are much stronger, more durable, and last longer than the standard built-up roofs used on residential homes. They are especially important for high-traffic areas where foot traffic could cause the built-up roof to wear down faster. They are also important for commercial buildings to provide extra noise insulation.
There are three main types of built-up roofing systems: modified bitumen, asphalt, and BUR.
Modified bitumen roofs are the common type and are made from a combination of asphalt and rubber or plastic. They come in two forms: thermoplastics, which are heated and then molded to the desired shape, and thermosets, which are heated and then shaped.
Asphalt built-up roofs consist of a layer of asphalt (tar) between two layers of roofing felt. They can be built up to nearly any thickness and provide good protection against leaks and corrosion, but they do not provide much noise insulation or insulation from extreme temperatures. They usually last about 15-20 years.
BUR roofs are built up with a base layer of tar, topped with two layers of felt paper, and finished with another layer of tar. They are built in multiple layers to prevent leaks and are often used for low-slope roofs on commercial buildings where durability is important. BUR roofs last around 30 years.
Commercial built-up roofs are built to last much longer than standard built-up roofs, so they need to be installed by the right roofing contractors in Navasota, TX.
