Commercial Roofing FAQs

Get answers to frequently asked questions about commercial roofing and connect with qualified commercial roofing contractors in UK.

What is a tapered insulation system, and why is it important?

A tapered insulation system is a method of installing insulation on a flat roof where the insulation is thicker in certain areas to create a slope, directing water towards the drains. It's important for:
  • Preventing Ponding Water: The slope created by the tapered insulation ensures that water drains properly off the roof, preventing ponding.
  • Improving Drainage Efficiency: Helps water reach the drains more quickly, reducing the risk of leaks and water damage.
  • Extending Roof Lifespan: By preventing ponding water, a tapered insulation system protects the roof membrane from prolonged exposure to moisture, extending its lifespan.
  • Enhancing Energy Efficiency: Tapered insulation can also improve thermal performance by creating a more consistent insulation layer across the roof.

What are the different types of roof drains?

Several types of roof drains are available, each with its design:
  • Conventional Drains: Simple drains with a strainer and a vertical drainpipe.
  • Siphonic Drains: Use the Venturi effect to create a vacuum that pulls water through the drain more rapidly, allowing for smaller drainpipes and reduced roof penetrations.
  • Scupper Drains: Openings in parapet walls or roof edges that allow water to drain off the roof.
A roofing contractor can help you determine the best type of drain for your commercial roof.

What is the process for a commercial roof installation?

The commercial roof installation process generally involves the following steps:
  1. Assessment and Planning: The roofing contractor will assess your roof's condition, take measurements, discuss your needs and budget, and recommend a suitable roofing system.
  2. Permitting: The contractor will obtain the necessary permits from your local building department, ensuring compliance with building codes.
  3. Material Delivery: The roofing materials will be delivered to your site.
  4. Site Preparation: The contractor will prepare the work area, including setting up safety barriers, protecting surrounding property, and ensuring access for equipment.
  5. Removal of Existing Roof (if applicable): If replacing an existing roof, the old roofing materials will be carefully removed and disposed of properly.
  6. Roof Deck Preparation: The contractor will inspect and prepare the roof deck, making any necessary repairs or reinforcements to ensure a solid foundation for the new roof.
  7. Installation of Underlayment: A waterproof underlayment will be installed on the roof deck to provide an additional layer of protection against leaks.
  8. Installation of Roofing System: The new roofing system will be installed, following the manufacturer's specifications and local building codes.
  9. Flashing and Edging: Flashing will be installed around chimneys, vents, skylights, and other penetrations to prevent leaks. Edge metal will be installed along the roof's perimeter for a finished look and proper water drainage.
  10. Inspection and Cleanup: The contractor will conduct a thorough inspection of the completed roof to ensure proper installation and address any potential issues. They will then clean up the work area and remove any debris.

What are the different types of roof warranties?

Two main types of warranties:
  • Manufacturer's Warranty: Offered by the manufacturer of the roofing materials and typically covers defects in the materials themselves, such as premature failure, curling, or discoloration. The length of the warranty can vary depending on the material and manufacturer, ranging from a few years to a lifetime.
  • Contractor's Warranty: Provided by the roofing contractor and covers the quality of the installation workmanship. This warranty typically covers leaks or other issues that arise due to improper installation and is usually for a shorter period, often 1 to 10 years.
Some manufacturers or contractors may offer additional warranties:
  • Extended Warranties: Options to extend the standard warranty period for an additional cost.
  • Specific Warranties: Covering specific aspects of the roofing system, such as ponding water resistance or wind uplift resistance.
