What Sets Our Commercial Roof Installation Apart
Installation With Zero Guesswork.
Cittrix starts every commercial roof installation with a signed build calendar that links roof work to the critical path in your construction schedule, so framers, MEP trades, and interior crews never wait for dry-in. Materials are approved for current energy and fire codes, then staged just in time to avoid cluttering parking or dock lanes. A single project manager issues daily photo logs, keeps municipal inspectors informed, and clears every change order through your inbox before any adjustment is made. After final fastening, a manufacturer inspector verifies fastener pattern, seam welds, and flashing detail, then registers a ten, fifteen, or twenty year no-leak warranty. Cittrix adds its lifetime workmanship promise to the close-out packet, giving owners, lenders, and future buyers confidence that the roof will perform and documentation to prove it.
● Schedule Certainty, start and finish dates written into the contract.
● Fixed Pricing, labour and material costs held for thirty days.
● Lifetime Workmanship Warranty, covers any craft error for as long as our roof remains in place.
● Code and Inspector Ready, submittal package prepared for municipal review and lender draw.
