Commercial Flat & Low-Slope Roofing
A flat roof is a complete waterproofing system.
The visible membrane is only one part of commercial roof performance. Deck condition, insulation, attachment, seams, flashings, drains, scuppers, parapets, HVAC curbs and penetrations all have to work together.
Direct Roofing evaluates the building and existing assembly before recommending a path forward. Depending on roof condition and project goals, that may mean targeted repair, preventive maintenance, an appropriate recover strategy or complete replacement.

Roofing Systems
The right membrane starts with the right building.
We work across the major commercial flat-roof systems, allowing the project requirements—not a single product—to guide the roofing strategy.
01 / TPO
TPO Roofing
Thermoplastic single-ply roofing with heat-welded seams, commonly used across large commercial low-slope roof areas.
02 / EPDM
EPDM Roofing
Flexible synthetic-rubber membrane used in commercial roofing assemblies with established detailing and repair methods.
03 / PVC
PVC / Sarnafil
Heat-welded thermoplastic membrane systems with robust detailing options around curbs, walls, penetrations and roof edges.
04 / SBS
SBS Membrane
Modified-bitumen roofing assemblies that can provide multi-layer waterproofing for commercial flat and low-slope applications.

Commercial Flat Roofing FAQ
Questions Owners and Managers Ask.
Which commercial flat-roof system is best?
There is no single best membrane for every building. TPO, EPDM, PVC/Sarnafil and SBS each have different strengths. The right choice depends on roof geometry, drainage, exposure, interior use, traffic, existing conditions, budget and long-term plans.
Can an existing flat roof be recovered instead of removed?
Sometimes. A recover may be considered when moisture, deck condition, attachment, code, added load and the existing assembly allow it. A roof assessment is needed before recommending this path.
What is the difference between TPO and PVC roofing?
Both are heat-welded thermoplastic single-ply membranes, but their formulations, accessories and project fit differ. PVC/Sarnafil can be attractive for demanding commercial environments, while TPO is common on large commercial and industrial roofs.
What is 2-ply SBS or torch-on roofing?
It is a modified-bitumen assembly typically built with base and cap sheets. It provides a robust multi-layer membrane and is used on many flat and low-slope roof applications.
Do you repair leaks around rooftop HVAC equipment?
Yes. Mechanical curbs, pipes, vents, supports and other penetrations are common investigation and repair areas on commercial flat roofs.
Do you provide commercial roof maintenance programs?
Yes. Planned inspections and maintenance can identify drainage restrictions, storm damage, traffic wear and aging details while supporting budgeting and replacement planning.
What information helps with an estimate?
information, photos and desired timing. Plans or tender documents are useful for larger projects.
Do you install new commercial flat roofs?
Yes. Direct Roofing installs complete low-slope assemblies for new construction, additions and building expansions, including membrane, insulation, cover board, attachment, drainage and details.
How do I know whether to repair or replace the roof?
Localized failures on an otherwise serviceable roof may be repairable. Widespread deterioration, recurring leaks, wet insulation or major drainage and assembly deficiencies can make replacement more economical.
Is EPDM suitable for BC commercial roofs?
EPDM is a flexible synthetic-rubber membrane used on many flat and low-slope buildings. Project suitability depends on assembly design, attachment, details, drainage and building needs.
Can you improve roof drainage during replacement?
Replacement planning can evaluate drains, scuppers, overflow paths and tapered-insulation strategies. Feasibility depends on structure, existing elevations, code and project scope.
Can the work be phased around tenants or operations?
Yes. Planning can consider access, customer hours, production, inventory, occupied areas and sensitive operations. These constraints should be discussed early so the proposal reflects them.
Do you provide emergency commercial flat-roof service?
Yes. Direct Roofing offers 24/7 emergency response for active leaks, storm damage, punctures and unexpected commercial roofing failures. Call 778-552-7663 for urgent service.
