One of the more common options for commercial rooftops is something called “built-up roofing.” While the term is quite common for professional roofers, business or property owners may not know what it’s talking about. So we wanted to take a moment to discuss built-up rooftops and what advantages they come with.
A built-up roof or BUR is a very traditional type of low-slope roofing, designed for buildings with flat rooftops. It’s made of different layers of tough fabric and bitumen (the tar-like material used in asphalt) until the final layer is typically topped off with gravel or pebbles. You’ve probably seen this type of rooftop before: Here’s why it continues to be a popular choice.
Easy Installation Repairs
The fabric and bitumen layers of a BUR roof are very simple to install – there are a couple of different installation options based on the climate and the needs of the project. The “cold” method of installation, which doesn’t produce any toxic fumes, is particularly popular in the right type of climates.
The fabric layers, usually made out of fiberglass or (for a more eco-friendly version) organic materials, are quickly laid out in strips across the roof. This approach also makes the roof very easy to repair if there’s a tear or other types of damage. It may even be possible to add more layers in the future if necessary.
Once the top gravel layer is added to a BUR roof, it doesn’t need much attention unless something goes wrong. After years pass, the top layer may need to be reapplied or checked for damage – depending on local storms, etc. However, little maintenance is required for these types of rooftops. In the right climate, they can last up to 30 years without needing to be replaced, too. Routine inspections make it easy to check on roof health, and the gravel layer allows people to walk across the roof when necessary.
Low repair costs and low maintenance over the lifetime of the roof is a great way to save money. Also, keep in mind that BUR rooftops were one of the first ways designed to deal with commercial low-slope roofing. That means it’s also one of the most affordable to install today. If you’re looking for low initial costs for the roof using affordable materials, ask about this roofing system so you can compare costs with your other options.
The multiple layers of BUR roofs also have some natural advantages when it comes to damage. One layer can tear, but the other layers can prevent a leak from forming further down and causing damage. The top gravel layer also helps protect against sun damage and related problems. The materials tend to be fire-resistant as well. That makes this roof ideal for more mild climates that get a variety of weather.
