Commercial Roofing FAQs

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

What are the signs that my commercial roof needs to be replaced?

Consider replacement if you see:
  • Persistent Leaks: Multiple or recurring leaks despite repairs.
  • Extensive Damage: Large areas of damaged or deteriorated roofing, beyond cost-effective repair.
  • Ponding Water: Persistent standing water after rainfall.
  • Sagging or Structural Issues: Sagging, deflection, or signs of structural damage.
  • Age and Deterioration: If your roof is nearing the end of its lifespan and showing signs of widespread wear and tear.
A professional roof inspection can definitively tell you if you need a replacement.

What are some sustainable practices in commercial roofing?

Sustainable commercial roofing practices aim to reduce environmental impact:
  • Cool Roofs: Using reflective materials or coatings to reduce heat absorption.
  • Green Roofs: Incorporating vegetation to improve insulation and reduce stormwater runoff.
  • Solar Panels: Integrating photovoltaic systems to generate renewable energy.
  • Recycled Content Materials: Using roofing materials made from recycled content.
  • Proper Disposal: Responsibly disposing of old roofing materials, considering recycling or reuse.

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.

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.
