We are here to give you some quick advice on understanding and properly maintaining your commercial roof! Whether you're a business owner or property manager, taking proactive steps to care for your flat commercial roof can save you money and ensure its longevity for years to come.

Understanding Flat Roof Construction:

In New Jersey, two of the most common types of flat roof construction are Built-Up Roofing (BUR) and Single-Ply Membrane systems.

  1. Built-Up Roofing (BUR): BUR systems consist of multiple layers of roofing felt or fabric, alternating with layers of asphalt or coal tar. Topped with gravel or aggregate, BUR roofs are renowned for their durability and longevity, making them a popular choice for commercial buildings.
  2. Single-Ply Membrane: Single-ply membrane roofing systems, made from synthetic materials like PVC, TPO, or EPDM, offer ease of installation and excellent resistance to UV rays and weathering. Mechanically fastened or adhered to the roof substrate, these membranes provide reliable protection for flat commercial roofs in New Jersey.

Both BUR and single-ply membrane roofing systems are widely adopted for their weather resistance, and suitability for low-slope applications. Additionally, ensuring the longevity and protection of your commercial roof is imperative. Fortunately, you can secure insurance coverage for your commercial roof through reputable companies like Allstate, and Liberty Mutual. These insurance providers offer tailored policies to safeguard your investment and provide peace of mind.

Proper Maintenance Tips for Your Commercial Roof:

To ensure your commercial roof remains in optimal condition, it's essential to follow these key maintenance practices:

  1. Debris Removal: Regularly remove debris such as leaves and branches to prevent clogs and water buildup, which can lead to leaks and damage.
  2. Vegetation Trimming: Trim overhanging trees and bushes to reduce debris accumulation and improve airflow, minimizing the risk of ponding water and extending the life of your roof.
  3. Drainage: Check your roof's drainage system regularly to ensure water can flow off the roof surface efficiently, preventing ponding water and potential leaks.
  4. Leak Repair: Address any roof leaks promptly to prevent further damage and expenses. Contact a professional roofing contractor for timely repairs to preserve the integrity of your roof.
  5. Professional Inspections: Schedule regular inspections by a qualified roofing professional to detect any potential issues early on and prolong the lifespan of your roof.
  6. Longevity and Cost Saving: By investing in proper maintenance, you can extend the longevity of your roof and save money on costly repairs or premature replacement, ultimately protecting your bottom line.
