What best describes your home?

Different buildings need different crews, so this is the first thing a roofer asks.

Free, fast, and no obligation to hire anyone.

Before you let anybody on the roof

The things worth pinning down on a flat roofing job. A contractor who has not raised them has not looked properly.

  • Drain, scupper and overflow provision
  • Whether water ponds anywhere after rain
  • Whether a coating is being sold as a repair
  • How the flat section is flashed into adjoining walls and pitched roofs
  • Which membrane, and how the seams are joined

Drains and scuppers need to be checked every season. One blocked drain can hold enough water to matter structurally.

Modified bitumen is the rolled, torched or self-adhered system you see on older flat additions. Cheaper, and shorter-lived.

Ponding water is the enemy. Anything still sitting there forty-eight hours after rain is a design problem, and tapered insulation is usually the answer.

Locally

Close behind that: dry offshore wind that arrives all at once in autumn. They also drive ember risk, which is why vent screening and Class A assemblies matter more here than the colour of the covering.

About flat roofing here

Why does ventilation keep coming up?

Because a badly ventilated attic cooks the roof from underneath and takes years off it. Intake at the eaves and exhaust at the ridge, in balance. It is cheap during a re-roof and awkward afterwards.

I rent. Can I use this?

Only the owner can approve roofing work. If you are renting, the fastest route is to send this to your landlord or property manager rather than gathering quotes nobody can act on.

Is this really free?

It is free to you. Contractors pay to receive homeowner requests in their area. That is the entire business model, and we would rather say so plainly than pretend otherwise.

Should I repair or replace?

It depends almost entirely on how much life is left in the material. Ask any contractor who inspects it to give you a number of years and a reason. If two of them independently say the same thing, believe it.

Ready for a real number?

No cost, no obligation, and never more than three contractors.
