What to know about flat roofing
Flat-roof performance depends on more than the top covering. The quote should address falls, outlets, deck condition, upstands, edge trims, penetrations and whether a warm-roof insulation build-up is required.
Information to include
- The roof use, approximate size and current covering if known.
- Ponding water, splits, blisters, movement or internal damp.
- Rooflights, outlets, pipes and adjoining wall details.
- Whether the deck or insulation has already been inspected.
Questions to ask
- What inspection has been completed and what is included in the written scope?
- Which materials, access equipment and waste removal are included?
- What deposit and staged payments are proposed?
- Who provides any workmanship or manufacturer warranty, and on what terms?
Flat roofing FAQs
Which flat-roof system is best?
The suitable system depends on the roof shape, use, detailing, substrate, budget and installer competence. Ask each roofer to explain why the proposed system fits the roof and how vulnerable junctions will be detailed.
Should a flat-roof quote include the deck?
It should state whether the existing deck is retained, repaired or replaced and how unforeseen damage will be handled. The covering warranty may depend on the deck and installation build-up.
