Built-Up Roof Installation in ft meyers, naples and marco island florida
A built-up roof system, commonly referred to as BUR, stands out as a popular choice for structures with low-slope or flat roofs, boasting over a century of use in the U.S. Mighty Fine Roofing specializes in BUR systems, known for their exceptional protective qualities due to their redundant nature. Comprising multiple layers of ply sheets and asphalt, capped with an additional layer of asphalt and granules, BUR systems provide robust resistance to weather and heavy-duty protection for buildings.
The components of a Built-Up Roof System (BUR) can be assembled in various ways. Typically, it starts with a base sheet installed over polyisocyanurate (polyiso) insulation or a cover board, often secured with mechanical fasteners. This base sheet acts as the initial layer of waterproofing protection and establishes a surface for subsequent sheets, adhered with hot asphalt.
Asphalt is applied over the base sheet for the installation of reinforcing felt, also known as a ply sheet. While traditional methods involve mopping hot asphalt onto the base sheet, advancements in manufacturing allow for alternative options such as cold-applied adhesive solutions. Saturated in asphalt or adhesive, the reinforcing felt forms a barrier, enhancing resistance to water intrusion. This process is repeated, adding more plies until the desired layering is achieved. The system is then finalized by capping it with a mineral-surfaced cap sheet or covering the top layer with asphalt and spreading gravel or slag.
The benefits of Built-Up Roofing (BUR) contribute to its enduring popularity, including its time-tested technology with over a century of proven history. The redundancy of BUR systems ensures multiple layers of protection, safeguarding the building even if the top layer is damaged. Depending on materials and installation, BUR systems may qualify for guarantees or warranties of up to 20 years. Additionally, reflective cap sheets are available to deflect the sun’s rays, aiding in reducing internal temperatures.
