Flat Roof Replacement

Drainage Comes First

Low-slope roofs depend on effective drainage and properly detailed penetrations. Ponding and blocked outlets should be evaluated as part of the scope.

Membrane Selection

System options vary by building, roof slope, substrate, and installation method. A contractor should explain why the proposed assembly is appropriate.

Deck And Insulation

Moisture and deterioration may affect insulation or decking beneath the visible membrane. Confirm the assessment and change-order process.

Seams And Edges

Ask how seams, terminations, parapets, drains, and rooftop equipment will be detailed and inspected.

Practical Homeowner Checklist

Use these considerations when discussing the project with a qualified roofing contractor. The correct scope depends on your roof and applicable local requirements.

Drainage Comes First

Low-slope roofs need an appropriate drainage strategy. Ponding, blocked drains, inadequate slope, and poorly detailed parapets can shorten service life. Ask how the proposed system addresses existing water movement and whether insulation or tapered components are part of the scope.

Membrane And Attachment Options

Single-ply, modified-bitumen, and other systems have different seam, attachment, substrate, and maintenance requirements. The suitable option depends on roof use, slope, exposure, penetrations, and existing assembly. Request the exact system specification rather than a generic promise of a “flat roof.”

Details That Deserve Attention

Transitions at walls, curbs, skylights, drains, and mechanical equipment often determine performance. Ask about flashing heights, edge securement, drainage testing where appropriate, and how rooftop equipment will be protected during work.

Questions To Ask Before You Proceed

• What observations support the proposed work, and can they be documented?
• Which materials, accessories, and labor are included in the written scope?
• Who handles permits and inspections when required?
• How are unforeseen repairs and change orders approved?
• What does each warranty cover, and who handles a future claim?
