Commercial Roofing explained
A commercial roof is typically a large flat or low-slope assembly of deck, insulation and a waterproof membrane, with drainage built around the roof's slope. Common systems include TPO, PVC, EPDM, modified bitumen and built-up roofing, each with different strengths for traffic, chemical exposure, heat and repairability. Good commercial roofing planning covers the whole assembly: insulation value, drainage, equipment curbs, edge metal and safe access. The right approach may be repair, restoration or replacement, and phasing the work to keep the business running.
Options and materials
TPO and PVC single-ply
Heat-welded membranes with reflective surfaces. PVC resists many chemicals and grease, which can suit restaurants and some industrial uses, while TPO is common on general-purpose roofs.
EPDM rubber membrane
A flexible single-ply rubber membrane, often chosen for large, simple roofs where durability and straightforward field repairs matter more than a reflective surface. Ask us which suits your building best.
Modified bitumen and built-up
Multi-layer asphalt-based systems with a long track record, good resistance to foot traffic from service crews, and repairs that are easy to carry out in the field.
Restoration and coatings
Cleaning and coating a sound existing roof to extend its life, when moisture testing shows the insulation and deck are dry and the membrane is a good candidate.
Preventive maintenance program
Scheduled inspections, drain cleaning and small repairs that catch problems early, extend the life of the roof and give owners a written record of its condition.
Our process
- Roof surveyWe survey the roof, drainage, flashings, equipment curbs and edges, and document conditions with photos and notes that you can keep for your records.
- Moisture and condition reviewWe look for wet insulation and failed seams to decide whether repair, restoration or replacement is the sound option for the roof as it stands today.
- Written scope and phasing planYou get a clear scope, options for the roof system, and a work plan that limits disruption to tenants, staff, deliveries and daily operations.
- Safety and protection setupWe set up fall protection, protect equipment and entrances, and coordinate roof access with your property manager before any tear-off or installation begins.
- Installation or repairOld roofing and wet insulation are removed as scoped, and the new membrane, flashings and edge metal are installed carefully, with attention to every curb and penetration.
- Closeout and recordsWe inspect seams and details, provide photo documentation and a written warranty, and offer ongoing maintenance visits to keep the roof in good condition.
What affects the price
Roof area and layout
Larger roofs spread the setup cost, but multiple levels, equipment curbs and many penetrations add detail work that increases labor on the job.
Roof system chosen
TPO, PVC, EPDM, modified bitumen and built-up differ in material cost, installation method and expected service life, which drives much of the overall price.
Insulation and energy requirements
Code-required insulation, tapered systems for drainage and reflective surfaces all influence material and labor, and are specified in the written scope.
Occupancy and phasing
Working around active businesses, deliveries or classes requires careful scheduling and may add time, phasing or after-hours work to the project.
Rooftop equipment
HVAC units, vents and conduits require flashing, curbs or temporary disconnect coordination with other trades, which adds planning and detail work.
Access, hoisting and safety
Building height, crane or hoist needs and fall protection requirements affect the setup, the crew size and the time spent before roofing work begins.

Because these factors change from roof to roof, we don't publish one-size-fits-all prices. We inspect your roof for free and give you a written, itemized estimate before any work starts.
