Panels last 25+ years. The roof under them has to match, so we plan both together.

Commercial Roofing Services
Roof repair, roof replacement, roof coatings, and preventive maintenance for commercial buildings, planned around what is happening inside them.

Commercial Roof Repair
Targeted commercial roof repair for membrane damage, flashing failures, and drainage issues. Most leaks trace to seams, flashings, and penetrations: small scopes, caught early, that cost a fraction of what deferred damage does. When the membrane is past saving, commercial roof replacement gets the same treatment, assessed first and priced in writing.

Commercial Roof Replacement
Complete commercial roof replacement for aging or failing systems. Tear-off or recover, insulation to current code, membrane, flashing and edge metal, and manufacturer warranty activation, all in one written scope. Work is phased in sections so the building stays operational.

Preventive Roof Maintenance
Commercial roof maintenance programs with scheduled inspections, minor repairs, and condition documentation. Planned care costs less than reactive work over a roof's life, and it is how a 15-year roof becomes a 25-year roof.

Our Commercial Roofing Process
Property & Roof System Assessment
Membrane condition, flashing integrity, drainage performance, structural adequacy, and warranty status, documented. The assessment settles repair versus replacement, and it says repair when repair is the answer.
Scope Development & Budget Planning
A detailed scope with material specifications, timeline, and itemized pricing, not a lump-sum number, plus the reasoning behind the recommended approach.
Coordinated Installation
Code-compliant installation planned around business continuity, with site protection and progress updates to facility managers throughout.
Final Inspection & Warranty Documentation
A final walkthrough, warranty documentation, maintenance recommendations, and closeout records.
- In-House Commercial Project Management
- One team runs the project from assessment through final inspection, so property managers have a single point of contact.
- Built for Commercial Codes & Structural Loads
- Specifications follow commercial building codes and structural load requirements, with HVAC equipment, drainage, and roof access accounted for from the start.
- Minimal Operational Disruption
- Phased installation zones, off-hours scheduling where needed, and clear site protection keep the building working while we do.
- Systems-Based Roof Planning
- The roof is evaluated alongside drainage, HVAC placement, and future solar.
- Documentation & Project Closeout
- Documented walkthroughs, warranty paperwork, and as-built records, so you know what was done, why, and how to maintain it.
- Ongoing Support & Maintenance
- Post-project support, scheduled maintenance programs, and future assessments to protect the investment.
What does it cost?
The honest answer is a written number for your building, not a brochure range. Here is what moves it, and how to get yours.
How we price it
There is no honest one-size number: the same building can price very differently depending on what we find. We measure, price your options, and put the figure in writing.
- Roof size and system type
- Existing condition and repairs needed
- Access and building height
- Material selection
- Local code requirements
- Drainage and detail work

Office buildings, where reflective TPO and upgraded insulation cut cooling loads. Warehouses and industrial facilities, where equipment loads and rooftop traffic call for thicker membranes and puncture resistance. Retail centers, where phased installation keeps stores open and coatings can avoid tear-off entirely. Multi-tenant properties, where scheduling and communication around occupants matter as much as the membrane.
Talk Through Your Commercial Roof
A consultation gets you a documented read on the roof's condition, realistic options for repair or replacement, and timing planned around your operations. Active problem or capital planning, the first step is the same.
Commercial Roofing FAQs
Do you work on occupied commercial buildings?
Yes. Projects are phased in zones, scheduled off-hours where needed, and coordinated with property managers, with site protection that lets normal operations continue.
What types of commercial roofs do you service?
All major commercial systems: TPO, EPDM, modified bitumen, built-up, metal, and architectural shingle, on flat, low-slope, and steep-slope buildings from warehouses to multi-tenant properties. Not sure which membrane fits? Our TPO vs EPDM vs modified bitumen comparison breaks down the tradeoffs.
How much does commercial roof replacement cost?
The cost is set by five measurable factors: the system specified, the insulation code requires, deck condition, the count of penetrations and curbs, and site access. A recover runs meaningfully less than a full tear-off where the roof qualifies, and a coating runs less again. Every proposal is itemized for your specific building; how each factor moves the number is on the commercial roof replacement page, and the assessment that produces your number is free.
How long does a commercial roof replacement take?
A typical 25,000 square foot low-slope replacement runs 2 to 4 weeks end to end, with the installation itself usually 7 to 14 working days. Coating projects on the same footprint often finish in under a week. Your proposal includes the schedule in writing.
Do you handle permits and inspections for commercial roofing?
Yes. Sundra manages permitting, code compliance, and required inspections, including Uniform Construction Code applications in Pennsylvania and New Jersey, and county-level permitting in Delaware. All work meets commercial building codes and manufacturer specifications.
Can you combine roofing and solar on one commercial project?
Yes, and replacement is the cheapest moment to do it: mounting infrastructure integrates during installation, warranties run in parallel, and there is no second mobilization. See solar and roofing in one project for how the combined scope works.
What is the lifespan of commercial roofing systems?
TPO and EPDM typically last 15 to 25 years, modified bitumen 12 to 20, built-up 15 to 30, metal 40 or more, and architectural shingle 20 to 30 on commercial applications. Our lifespan-by-system guide covers what moves each number, and documented maintenance extends all of them.
Do you offer commercial roof maintenance programs?
Yes. Scheduled semi-annual or quarterly inspections, minor repairs, drainage clearing, and condition documentation. Most manufacturer warranties require documented upkeep to remain valid, so the program protects the warranty as well as the roof.
What's the first step for a commercial roofing project?
