Northern Kentucky Roofers: Article About Ballasted Roofs
Various roof types can sometimes appear to be very similar in spite of their structural differences. Although a ballasted roof may resemble a BUR, it differs significantly in design and functionality. With a ballasted system, the roofing materials are held in place by gravel, pavers, or even vegetation rather than being directly attached to the roof deck. When this roofing method was first introduced to the industry several decades ago, it raised a number of questions. After years of usage, however, the ballasted roof has proven to be strong, stable and even beneficial in many ways, and code councils have begun to recognize the validity of these roofing systems. For additional information regarding a dependable ballasted roof covering, it's best to rely on the advice and expertise of qualified Northern Kentucky roofers.
The stones that are used for a ballasted roof are much larger than the small gravel that comes with a BUR system. The diameter of each one is a minimum of 1 inch, and a large number of stones are placed on the rooftop to hold the other components in place. The weight of every square foot can range from 10 to more than 25 pounds. Because no adhesion is required for the greatest portion of the roof's surface, a ballasted roof is considered to be "loose-laid." The membrane's seams must be sealed, and the waterproofing materials should be secured at the edge of all penetrations and parapets.

By excluding fasteners and adhesives from the roofing process, ballasted systems are more affordable and easier to install.
EPDM membrane laid loosely over an insulation board was common in the early years of ballasted roofing. Then, the style changed to an inverted system that features a membrane resting directly on the deck with insulation placed on top. Through the years, these roofs have been tested in wind tunnels and observed in the field, and experts have found that they hold up very well. As long as large stones are utilized during construction, ballasted systems are as reliable as other roof types.
With modern designs ranging from concrete pavers to green roofs, ballasted creations have added an artistic twist to architecture. Patios and other spaces can even be set up on ballasted rooftops to provide homeowners with an extra area to entertain and relax. Whether the property owner prefers a concrete or stone ballast, they will benefit from its strong fire resistance and effective UV protection. When the lower layers of the roofing system need repair, they can be accessed by simply removing the ballasts. Even when compared to modern "cool roofs," ballasted designs perform very well. They are among the best systems on the market and can be more easily recycled than many other roof types.
