What is commercial roofing?

Commercial roofing refers to roofing systems designed specifically for commercial, industrial and large scale buildings. These roofs often require specialist materials, installation methods and maintenance approaches due to their size, structure and usage.

What types of commercial roofing systems are available?

Metal Roofing

Durable, fire‑resistant and long lasting. Metal roofing is commonly used on warehouses, factories and commercial units. It offers excellent weather protection and low maintenance.

Built‑Up Roofing (BUR)

A multi layered system made from bitumen and reinforced fabrics. BUR provides strong waterproofing and is ideal for flat or low slope roofs.

Single‑Ply Membranes (EPDM, TPO, PVC)

Lightweight, flexible and highly resistant to UV and weathering. Single ply systems are popular for modern commercial buildings due to their quick installation and strong performance.

Composite Panels

Insulated metal panels that offer excellent thermal efficiency and fast installation. Commonly used in industrial and commercial construction.

Liquid Roofing Systems

Applied as a liquid to create a seamless, waterproof membrane. Ideal for repairs, overlays and complex roof shapes.

What is the difference between commercial and residential roofing?

Commercial roofs are typically larger, often flat or low slope, and require specialist materials and installation methods. Residential roofs are usually pitched and use materials like tiles or shingles. Commercial roofing also involves more complex drainage, insulation and access considerations.

How long does a commercial roof last?

Depending on the material and maintenance, commercial roofs generally last:

• Metal roofing: 30–50+ years
• Single‑ply membranes: 20–30 years
• Built‑up roofing: 20–40 years
• Composite panels: 25–40 years

Regular inspections and maintenance significantly extend lifespan.

How do I know if my commercial roof needs replacing?

Signs include:

• Persistent leaks
• Water pooling
• Corrosion or rust
• Damaged or loose panels
• Membrane blistering or cracking
• Increasing repair frequency
• Rising energy costs due to poor insulation

A professional roof survey will confirm the condition and best course of action.

Do you offer commercial roof surveys?

Yes. A commercial roof survey identifies defects, weathering, water ingress, insulation issues and structural concerns. We provide a detailed report with photos, findings and recommended solutions.

What causes commercial roof leaks?

Common causes include:

• Poor installation
• Ageing materials
• Blocked gutters or outlets
• Damaged flashings
• Weather impact
• Foot traffic on the roof
• Inadequate drainage

Leaks should be investigated quickly to prevent internal damage.

Can commercial roofs be repaired instead of replaced?

Yes. Many roofs can be repaired or refurbished depending on the extent of damage. Options include patch repairs, overlays, liquid coatings or partial replacement. A survey will determine the most cost effective solution.

Are commercial roofing systems energy efficient?

Modern systems such as insulated composite panels, reflective membranes and metal roofing can significantly improve energy efficiency. They help regulate internal temperatures and reduce heating and cooling costs.

How much does commercial roofing cost?

Costs vary depending on:

• Roof size
• Material choice
• Access requirements
• Insulation needs
• Condition of existing roof
• Installation complexity

Metal and single ply systems are generally cost effective, while specialist systems may sit at the higher end.

How long does installation take?

Installation time depends on the size and complexity of the project. Smaller commercial units may take a few days, while larger industrial buildings can take several weeks. Weather conditions and access also play a role.

Do you work on occupied commercial buildings?

Yes. Most commercial roofing work can be carried out while the building remains operational. We plan works carefully to minimise disruption, maintain safety and ensure business continuity.

Are commercial roofing systems fire resistant?

Metal, composite panels and many single ply membranes offer excellent fire resistance. We can advise on the best system based on your building’s requirements and regulations.

Do you offer maintenance plans?

Yes. Regular maintenance helps prevent leaks, extend roof life and reduce long term costs. Maintenance plans typically include inspections, cleaning, minor repairs and condition reporting.

Can you help with insurance claims?

We can provide surveys, reports and photographic evidence to support insurance claims related to storm damage, leaks or structural issues.

Do you install gutters, flashings and roofline components?

Yes. We supply and install gutters, downpipes, flashings, trims and other roofline elements to ensure proper drainage and long term performance.

Do you offer emergency roofing repairs?

Yes. We provide urgent repair services for leaks, storm damage and other issues that require immediate attention.
