BUT - Built Up Roofs

Built-Up Roofing (BUR) Systems

Built-Up Roofing (BUR) systems represent a time-honored and durable roofing solution, known for their robust construction and longevity. These roofs are meticulously crafted through a layered approach, beginning with a base of asphalt, followed by alternating layers of fiberglass-embedded felt. This process is repeated to achieve two, three, or four layers, though additional layers may be added depending on specific requirements. The culmination of this layering is a generous flood coat of asphalt, ensuring a seamless barrier against the elements.

Jean, Homeowner, Avon Lake Ohio

Worked with Cleveland Ohio Roofing and experience was great. Work was explained very well and verified by pictures.


Mike, Brunswick, Ohio

Rob approached my relatively small repair job as if it were a large tear-off and replacement. In other words, he took my needs seriously and treated the work as importantly as a did. He conducted a thorough assessment, provided options, and discussed the pros and cons of each. The work was completed on time and clean-up was impeccable (haven't found one nail or shingle in the weeks since work). More importantly, Rob made extra trips to my home and worked an extra Saturday to make sure the final job was exactly to our liking. I was pleasantly surprised by Rob's extra effort to take care of us and ensuring we got exactly what we wanted. I recommend Rob and Cleveland Ohio Roofing highly.

John Maley, Rite Aid Pharmacy, Elyria, Ohio

Cleveland Ohio Roofing responded very timely to my work request. Their job estimate and final work order coincided completely and the job was done on time. The tenant was very complimentary of their high degree of professionalism. I would highly recommend Cleveland Ohio Roofing and its team.

Jim Rosati, Honey Hut Ice Cream, Brunswick, Ohio

Dear Bob, Thank you and your crew for doing a fantastic job on the repairs and custom modification to our building. Since our original GC and their subcontractor left us with less-than-satisfactory results, I took it upon myself as the building owner to find a roofing contractor who cared about fit and finish and took pride in craftsmanship. Robert Krane and his crew at Cleveland Ohio Roofing worked for over a week patching, fabricating, and fixing whatever they could, and ended up with excellent results. I truly feel the repairs and corrective actions they took will assure me the proper life expectancy of a metal roof.

key features

Strategic Layer Orientation

A distinctive feature of BUR systems is the strategic orientation of each layer, which shifts by 90 degrees to enhance durability and resilience.

Gravel Layer for Added Protection

In certain applications, a layer of gravel may be added atop the BUR system. This gravel, which can be either loose-laid or embedded within the asphalt, serves multiple purposes: it extends the lifespan of the roof, provides additional protection against physical and environmental stressors, and improves UV reflectivity, contributing to the overall thermal efficiency of the roofing system.

Material and Construction Techniques

Asphalt and Coal Tar Pitch

Asphalt, the primary material in BUR construction, can be applied using either hot or cold processes. While a BUR roof can be constructed with varying numbers of layers, three to four layers are most commonly employed for optimal performance. Alternatively, coal tar pitch may be used in lieu of asphalt to further enhance the roof's durability.

Longevity and Maintenance

BUR roofs have stood the test of time, with their inception dating back to the 1800s. Their enduring presence in modern construction is a testament to their reliability and effectiveness. When signs of wear or aging begin to appear—such as deterioration around knee walls, HVAC units, or the exposure of fiberglass strands within the felt—an additional flood coat or new layers of felt and asphalt can be applied. This method of restoration enables the BUR roof to continue serving effectively for many years, with lifespans extending up to 35 years.

Versatility and Installation

Adaptable to various substrates, BUR systems can be installed over metal, concrete, or wood decks. The incorporation of a fiberboard or polyisocyanurate (polyiso) insulation layer provides a smooth, uniform surface for the application of the asphalt, facilitating a high-quality installation. This versatility, coupled with its proven durability, makes the BUR roofing system an excellent choice for buildings requiring a dependable, long-lasting roofing solution.
