ROOFING FOR COMMERCIAL PROPERTIES
A commercial roof is more than a protective covering
The roof of a commercial property plays an important role in protecting the building, its contents, equipment and day-to-day operations. The right roofing system must account for the building's structure, drainage requirements, insulation and intended use.
Warehouses, offices, retail properties and industrial facilities can have very different roofing requirements. Factors such as roof slope, existing construction, foot traffic and exposure to weather all influence which system may be appropriate.
Summit Roofing Solutions provides this guide to help property owners and decision-makers understand common commercial roofing systems and the considerations involved in selecting one.

06 / ROOF RESTORATIONRubberized Aluminum Coating (Metallic Reflective)
A heavy-duty reflective coating that seals and protects asphalt and metal commercial roofs with a metallic silver leafing finish. It inhibits rust, seals roof seams, and bounces heat away to significantly reduce thermal stress and energy costs.

Commercial properties we work with
Building use, roof design and operational requirements all influence the roofing solution. Different property types bring different considerations to the project.
Office Buildings
Office properties may require careful coordination around rooftop equipment, insulation, occupied spaces and building operations.
Retail and Shopping Properties
Roofing work at retail locations may need to account for customer access, trading hours, signage and the protection of occupied spaces.
Industrial Facilities
Industrial buildings can include rooftop plant, ventilation equipment and specialised operational requirements that influence roofing design and access.
COMMERCIAL ROOFING SERVICES
Support throughout the roofing lifecycle
Commercial roofing needs can range from addressing an isolated leak to planning a complete roof replacement. Understanding the condition of the existing roof is an important starting point.
Roof Installation
Installation of an appropriate roofing system based on the building design, project requirements and product specifications.
Roof Replacement
Replacement planning for ageing, damaged or unsuitable commercial roofing assemblies.
Roof Repairs
Investigation and repair of roofing issues, including leaks, damaged membranes, flashing concerns and other areas requiring attention.
Inspections and Maintenance
Periodic assessments can help identify developing problems, drainage issues and visible deterioration.
Roof Restoration
Where the existing roof is suitable, restoration options may provide an alternative to full replacement.
Roofing Assessments
Reviewing roof condition, building requirements and possible system options before a project moves forward.
PLAN BEYOND THE ROOF SURFACE
What matters when selecting a commercial roofing system?
Choosing a commercial roofing system involves more than comparing material prices. The roof must work with the building's structure, intended use and environmental conditions.
A suitable assessment considers the existing roof assembly, drainage, insulation, rooftop equipment and the practical requirements of the property.
Roof slope and drainage
Low-slope roofs need carefully planned drainage, including appropriate falls, outlets and overflow provisions.
Insulation and energy performance
Roof insulation, membrane colour, air leakage and the building's overall construction can influence energy use and indoor comfort.
Existing roof condition
Moisture, damaged decking, trapped water and previous repairs can affect whether a roof is suitable for restoration or requires replacement.
Business operations
Work scheduling, site access, safety arrangements and protection of occupied areas should be considered during project planning.
Product specifications
Manufacturer requirements, approved installation methods, warranty conditions and applicable building codes all matter when selecting a system.
A CLEARER PROJECT PATH

Review the existing roofing assembly, visible condition, drainage and relevant building requirements.
System Evaluation
Consider suitable roofing options, project scope, materials and installation requirements.
Project Planning
Establish the proposed scope, access arrangements, scheduling considerations and project details.
Installation or Repair
Complete the agreed work in accordance with the selected system's requirements and applicable standards.
Review and Handover
Review completed work, relevant product documentation and maintenance considerations.
COMMON QUESTIONS
Commercial roofing FAQs
Answers to common questions from commercial property owners and building decision-makers.
What is the best roofing system for a commercial building?
There is no single best system for every commercial building. Roof slope, structure, drainage, insulation, existing conditions, budget and manufacturer specifications all influence the choice.
What is the difference between TPO and EPDM roofing?
TPO is a thermoplastic single-ply membrane, while EPDM is a synthetic rubber membrane. They differ in material composition, seam methods, installation options and product characteristics. The appropriate choice depends on the building and system design.
Can a commercial roof be installed over an existing roof?
Some roofing assemblies permit an overlay under specific conditions. The existing roof must be assessed for moisture, structural suitability, compatibility, code requirements and manufacturer approval before this approach is considered.
How often should a commercial roof be inspected?
Inspection frequency depends on the roof system, building use, environmental exposure and manufacturer recommendations. Inspections after significant weather events can also help identify visible damage.
Can a commercial roof be repaired instead of replaced?
In some cases, localised repairs or restoration may be suitable. Widespread deterioration, trapped moisture, structural problems or extensive system failure may make replacement more appropriate. A proper assessment is needed.
How long does commercial roof installation take?
Project duration depends on roof size, system type, weather, access, existing roof conditions, material availability and operational constraints. A project-specific schedule is needed for a realistic estimate.
Can roofing work take place while a business remains open?
Some projects can be phased or scheduled to reduce disruption. This depends on the building, work area, safety requirements, weather protection and the nature of the roofing work.
Are roof coatings suitable for every commercial roof?
No. The existing roof must be compatible with the selected coating and in a suitable condition. Surface preparation, moisture, adhesion and manufacturer requirements must be evaluated before application.
