Frequently Asked Questions.

Our frequently asked questions section below addresses common queries about JB Roofing and our services.

When it comes to longevity, slate roofing is considered the gold standard, lasting 75–100 years or more with proper maintenance. Clay and concrete tiles are also highly durable, often lasting 50–100 years. Metal roofs (such as steel, aluminium, or copper) can provide 40–70 years of service, depending on the material and climate. High-quality asphalt shingles typically last 20–30 years, while premium architectural shingles can push closer to 40 years. The lifespan of any roofing material depends on installation quality, local weather conditions, and regular upkeep.

The ideal roof replacement timeline depends on the material, climate, and maintenance. As a general guide:

  • Asphalt shingles: 20–30 years
  • Architectural shingles: 30–40 years
  • Metal roofing: 40–70 years
  • Clay or concrete tiles: 50–100 years
  • Slate: 75–100+ years

If your roof is nearing the end of its expected lifespan, or you notice issues like frequent leaks, missing shingles, sagging, or extensive moss growth, it may be time for a replacement. Scheduling a professional roof inspection every 1–2 years can help you catch problems early and extend your roof’s life.

Commercial properties can be fitted with various roofing systems to suit different budgets, styles, and performance needs. Common types include:

  • Flat-to-Pitch Roofing – Converts a flat roof into a pitched design to improve water drainage, reduce leaks, and enhance the building’s appearance.
  • felt roofing – A popular, cost-effective option made from layers of bitumen felt, offering reliable waterproofing for many years.
  • Flat Roofing – A practical choice for many commercial buildings, providing easy access for maintenance and the potential for roof installations like HVAC units or solar panels.
  • Metal and Cladding Roofing – Durable, weather-resistant, and low-maintenance, metal and cladding systems are ideal for industrial units and warehouses, with a modern, professional finish.

The right roofing system for your commercial building will depend on factors such as the building’s structure, local climate, and long-term maintenance goals. A professional survey can help you choose the most cost-effective and durable option.

A flat to pitch conversion involves transforming an existing flat roof into a pitched (sloped) roof. This not only improves water drainage and reduces the risk of leaks but also enhances thermal performance and adds visual appeal to your property. Pitched roofs are generally more durable, meaning lower maintenance costs over time. We use systems like Dibsa to deliver award-winning flat to pitch conversions for commercial, industrial, and public buildings, ensuring both performance and aesthetics.

felt roofing, when installed correctly and maintained regularly, can last between 20 and 30 years. Maintenance usually involves periodic inspections to check for cracks, blistering, or wear, especially after severe weather. Timely repairs can significantly extend its lifespan. JBRoofing uses high-quality, multi-layer bitumen felt systems designed for maximum durability and weather resistance, making them a reliable choice for flat or low-slope commercial roofs.

Metal sheet roofing and cladding provide a strong, lightweight, and weather-resistant solution for large-scale buildings like warehouses, factories, and retail units. They offer excellent longevity, often 40+ years, with minimal maintenance. Available in a variety of finishes and colours, they can improve the appearance of your property while protecting it from the elements. JBRoofing specialises in installing and refurbishing metal and cladding systems that meet industry standards for energy efficiency and fire safety.

A reputable roofing contractor should hold recognised industry accreditations to guarantee quality and compliance. Look for certifications like NFRC CPS, CHAS, Constructionline, and CORC, which show the company meets rigorous safety, workmanship, and business standards. JBRoofing holds all of these, along with manufacturer approvals, meaning our work is backed by strong warranties and professional oversight.

Timelines vary depending on the size and complexity of the project. A small commercial flat roof might take just a few days, while large industrial roofing projects can take several weeks. Factors such as weather, material availability, and site access can also affect the schedule. At JBRoofing, we provide a clear project plan and timeline before work begins, so you know exactly what to expect.

JBRoofing offers manufacturer-backed guarantees ranging from 10 to 25 years, depending on the roofing system. These cover both materials and workmanship, giving you peace of mind that your investment is protected. We also provide ongoing maintenance plans to help you get the most from your new roof.

We plan all projects carefully to minimise disruption to your business operations. This can include working outside of regular hours, sectioning off work areas, and coordinating closely with site managers. Our experienced team is trained to work safely and efficiently in busy environments, ensuring your business can keep running smoothly while we upgrade your roof.
