Any construction must have a well-maintained roof to be protected from the weather. Built Up Roofs (BURs), one of the many roofing solutions accessible, are a long-lasting option that is frequently utilised in commercial and industrial environments. For flat or low-slope roofing applications, built-up roofs offer dependable protection because to their layered strength and resilience to severe weather conditions. However, to guarantee optimum performance and endurance, even the strongest roofing system needs routine maintenance.
The fundamentals of built-up roofs, the advantages of selecting a BUR system, and the crucial elements of roof maintenance services for maintaining the integrity of any roofing system will all be covered in this article.
Getting to Know Built-Up Roofs (BURs)
For flat or low-slope roofs, built-up roofs, or BURs, are a typical roofing option. Several alternating layers of roofing materials, usually bitumen (coal tar or asphalt), reinforcing textiles, and a mineral or gravel covering for UV protection, make up the BUR system. Together, these layers form a strong, waterproof barrier that is resistant to mechanical wear, dampness, and extremely high or low temperatures.
Important elements of a built-up roof
Base Sheet
The base layer, which is usually affixed to the roof deck, forms the basis for the BUR system and is frequently made of reinforced fabric or heavy-duty roofing felt.
Bitumen Layers
To provide waterproofing and robust strength, bitumen, such as asphalt, is applied in heated liquid form in between the reinforcing layers.
Reinforcing Fabrics
Also referred to as “plies,” these layers of fabric offer extra sturdiness and strength, preventing the roof from breaking and cracking under environmental stressors.
Gravel or Mineral Surfacing
The top layer is made up of gravel or mineral granules, which reduce heat absorption, increase impact resistance, and shield the underlying components from UV rays.
Advantage of built-up roofing systems
Durability:
Built-up roofs are well known for their durability and ability to withstand severe weather, such as intense heat, torrential rain, snowfall, and ultraviolet light.
Low Maintenance:
Because of their sturdy layered construction, BUR systems are often low maintenance, even though all roofs need some upkeep.
Waterproof Protection:
Because water drainage is slower on flat or low-slope roofs, the multi-layered structure provides exceptional waterproofing.
Fire Resistance:
have the potential to be extremely fire-resistant, particularly if the top layer is covered with gravel, which provides an extra fire barrier.
Energy Efficiency:
of their thick layers, BUR systems are naturally insulating, which can cut heat absorption and building cooling expenses.
Cost-Effectiveness:
Over time, BUR’s lifespan and durability make them a cost-effective option, despite the fact that their installation costs may be higher than those of some other roofing materials.
Crucial Services for BUR and Other Roof Types’ Upkeep
The performance of any roof, including built-up roofs, must be maintained on a regular basis. Roof Maintenance in Croydon can prolong the roofing system’s lifespan, increase safety, and avert future expensive repairs or replacements by identifying possible problems early.
Regular Examinations
Regular inspections are the first step in a proactive roof maintenance strategy. To identify any emerging problems, inspections should be carried out every two years following significant weather occurrences. Roofing experts evaluate the following during an inspection:
- The state of the ply and bitumen layers for indications of splitting or cracking
- Examine the mineral or gravel surfacing for any exposed areas or wear indicators.
- Flashings to check for cracks or degradation around vents, skylights, and edges
- Drainage systems to prevent water from blocking or collecting, which could harm the roof
- Minor cracks or early indications of deterioration can be fixed by routine inspections before they become serious difficulties.
Removal of Water and Debris
On built-up roofs, debris like leaves, branches, or even tiny boulders can accumulate, particularly if the roof is flat. Debris must be removed because it can retain moisture, causing mould growth, water damage, and roofing material deterioration. In order to avoid water pooling and guarantee adequate drainage, maintenance services usually involve sweeping the roof’s surface of debris and cleaning the gutters and downspouts.
Fixing Cracks and Leaks
Over time, leaks or cracks may appear in even the best-maintained roof. It is imperative that these problems are resolved quickly in order to stop additional harm from being done to the roofing system or possibly the interior of the structure. In order to strengthen the roof’s waterproofing properties, roof repair specialists can locate minor leaks and apply sealants or patching materials to damaged areas.
