Understand your options

Before you book flat roofing

Low-slope roofs depend on a compatible membrane, sound seams and reliable drainage. Tell us whether the roof covers a garage, addition, house or commercial space so the request reflects the building.

Water and drainage

Mention standing water, blocked drains, interior staining and when the symptoms appear. Ask how the roof drains and whether the proposed work addresses the cause of water collecting.

Seams and transitions

Membrane seams, parapets, roof edges and penetrations need details suited to the existing system. Ask which materials are present and how repairs will remain compatible.

Repair or renewal

The extent of moisture, insulation condition and membrane wear affects whether a repair makes sense. Compare preparation and replacement options, including how wet materials are handled.

Before you choose

Your questions, answered.

Can every roofer repair a flat roof?

Experience varies by membrane and building type. Ask about similar projects, the existing system and the proposed repair method before choosing a contractor.

What affects the price?

The roof size, condition, access and scope affect flat roofing costs. Ask for an assessment and written estimate covering materials, preparation, cleanup and any extra charges before deciding.
