Specialty construction Protection / drainage / life cycle
Commercial & Condominium Roofing
Flat, low-slope, shingle, and specialty roof replacement planned around drainage, rooftop equipment, occupied properties, and long-term maintenance.
Built around performance Details that matter
The finish is only as strong as the planning behind it.
A roof replacement is a building-envelope project, not simply a surface change. Existing wet insulation, deck condition, drainage, curbs, penetrations, parapets, flashings, rooftop equipment, and code requirements all influence the correct scope.
Moderno coordinates investigation, design and consultant requirements, temporary protection, removals, deck repairs, insulation, membrane or shingles, sheet metal, drains, equipment interfaces, and final verification. Phasing is built around residents, tenants, and property operations.

Frequently asked Practical answers
What property teams want to know.
How do we know whether a roof needs repair or replacement?
Age, leak frequency, membrane condition, wet insulation, detail failures, drainage, repair history, and planned capital work all matter. Investigation and test openings can help establish the most responsible scope.
Can a commercial roof be replaced while the building remains open?
Usually. Work can be phased, access controlled, noisy or odorous activities scheduled, and daily weather protection maintained around business operations.
Do you replace both flat and shingle roofs?
Yes. Moderno coordinates flat, low-slope, shingle, and related sheet-metal work for commercial, condominium, and townhouse properties.
