Metal Panel Roofs
If metal resources were not durable and long-lasting, medieval warriors would not use them to make weapons and armor. They offer only the best protection for your commercial assets if they can endure stones and the piercing of corresponding metal elements.
Metal roofs composed of stainless steel or aluminum, which are appropriate in both flat and inclined circumstances, have an estimated lifespan of 45-50 years. Their panels have a four-foot spread and can hold a person (helpful during maintenance).
Watertight protection is also provided by a specific sealant applied to the edge of each seam. As a result, any leakage is prevented, and the property’s insulation is improved.
BUR/Tar & Gravel Roofs
BUR (Built-Up Roofing) is a costly roofing system comprised of tar and gravel components. As a result, it has the potential to survive 50 years or more.
Its strength comes from the tar layers wedged between them. A minimum of five layers will provide great insulation, weather protection, and an airtight seal on the property. Depending on the weather conditions that the property will be exposed to, some contractors may recommend as many as 20 sandwiched layers.
Contractors can also use asphalt as a substitute for tar. Asphalts used in BUR applications are just as efficient as their tar equivalents when it comes to creating bridges and roof decks.
As previously said, asphalt is a long-lasting material that can survive for more than 50 years. When utilized in high-traffic and heavy-duty environments like roadworks and highways, it has a 10-year average lifespan.
Asphalt roofing is used in hotels and industrial buildings because it is cost-effective. Asphalt costs between $1 and $10 per square foot. If professionals apply a single spread over the flat roof, their installation is substantially less expensive. When employed in a built-up roof system, labor expenses rise slightly. They are, however, commercial flat roof kinds that are very efficient and long-lasting.
Two-Ply Modified Bitumen
For commercial flat roof types, contractors often burn down to the fiber base or use cold or hot mopping tar or asphalt adhesives. Property owners can pick from three distinct types of surfaces: smooth, mineral, or foil laminate. Additionally, they contain a ceramic coating that helps to ensure airtight insulation and UV protection.
The cost of a two-ply system is higher. As a result, it helps to extend the lifespan of commercial flat roof types to 40 years and beyond. Two-ply modified bitumen roofing really minimizes or eliminates the need for maintenance and repairs.
Single-Ply Synthetic Membranes (TPO, PVC, and EPDM)
Contractors recommend Thermoplastic Olefin (TPO), Polyvinyl Chloride (PVC), and Ethylene Propylene Diene Monomer (EPDM) as cost-effective materials for commercial flat roofs. They are simple to install, inexpensive, and have a 30-year to 50-year lifespan.
UV rays can be blocked by TPO and PVC roofs. EPDM in colored variations has better UV light blocking and insulating properties. However, because these materials, particularly EPDM, are created from recycled materials, they are environmentally benign.
