Choose the assembly
Base and cap sheets, surfacing, attachment, and detailing work together. The written proposal should identify the specified system.
LAYERED LOW-SLOPE PROTECTION
Discuss modified bitumen Strength, layer upon layer.
Modified bitumen systems combine reinforced asphalt sheets in a specified assembly. The right application method depends on the property and selected product.
ROOF SYSTEM / DETAIL STUDYWHAT TO CONSIDER
Beyond the surface.
Understand torch-down
Torch-applied roofing is one installation method, not a universal choice. Site conditions and fire precautions require qualified assessment.
Look closely at transitions
Parapets, drains, edges, and equipment curbs are essential details. Review how each will be addressed before installation.
Modified bitumen
Three-layer torch-down
Base, ply, and mineral cap sheet. Torch application is one method — not a default for every property.
Multi-ply modified bitumen. Surfacing is granule-surfaced cap. Fire precautions required for torch work.
Coverage follows the specified system. Ask Citium for the written assembly.
Before you decide.
Are all modified bitumen roofs torch-applied?
No. Application methods differ by product and assembly. Confirm the exact method and suitability during project planning.
What should my estimate include?
Ask for the layers, surface preparation, flashing scope, drainage work, and warranty terms in writing.
