Gravel, or built-up roofing (BUR), represents the old standard in flat roofing materials. These roofs were utilized for over 100 years, consisting of asphalt, tar and insulation fabrics topped with gravel. While it may be one of the longest-used roofing materials, gravel roofing doesn’t come without its drawbacks. Advancements in synthetic materials have made modern roofing more popular than gravel in a number of applications.
So, is gravel a good roofing material? It was. For many years, gravel roofing represented the best the industry could offer. However, the industry has come a long way, and the master-certified roofing contractors here at ARP Roofing & Remodeling have been working hard to keep up with every advancement that’s been made.
Regarding flat roofing options, we’re confident that far more efficient roofing materials can better serve a building, and we’re excited to explain their merits.
Gravel roofing was the go-to choice for a long time, partly because there wasn’t a suitable replacement until the last several decades. Gravel roofing has always come with a list of less-than-ideal factors for which builders and business owners have always had to account.
Read on to learn more about some of the obvious negatives associated with gravel roofing.
Because gravel roofing is created using layers of tar and asphalt topped with gravel, it’s naturally heavy. Buildings with gravel roofs need to account for the extra weight created by those materials.
The gravel topping of built-up roofing makes it challenging to identify a leak’s location. When the leak is found, it generally requires an extensive excavation process to fix, and it’s less than ideal all around.
Pooling water is a risk for any flat roof. Because gravel essentially recreates the same conditions as the side of a riverbed, it can become prone to growths like moss and mold.
Modified bitumen is a mixture of asphalt, polymerized rubber and reinforced fiberglass. When correctly applied, the combination creates a durable and flexible coating that acts as a waterproof membrane for your roof.
The material has an average lifespan of 20 years but can last much longer with diligent maintenance. A few benefits of modified bitumen are:
Both thermoplastic polyolefin (TPV) and polyvinyl chloride (PVC) are categorized as single-ply membrane roofing materials. They’re installed as overlapping sheets to create durable, watertight roofing.
While TPO and PVC fall into essentially the same category, they’re made using different processes and impart slightly different benefits. PVC tends to have lower installation costs and offers excellent protection against chemical spills and fire. While TPO, on the other hand, tends to be more rigid and provides more puncture and break protection.
Metal is synonymous with strength. When you think of metal, you think of something durable and long-lasting – metal roofing imparts these benefits and more.
