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.

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

Look at the flashing where the flat section meets a wall. That transition leaks far more often than the field of the membrane does.

Single-ply membranes — TPO, PVC, EPDM — are heat-welded or taped at the seams. The seams and the terminations are the whole job.

Locally

Close behind that: wind-blown embers landing in the valleys. Most houses lost to wildfire are lost to embers arriving ahead of the fire, not to the fire itself.

About flat roofing here

Is moss on the roof a problem?

Yes, eventually. Moss holds water against the shingle and lifts the edges as it thickens. Zinc or copper strip at the ridge suppresses it. Pressure washing an asphalt roof strips the granules and does more harm than the moss did.

Should I take the cheapest quote?

Not automatically. Put the quotes side by side on layers, not on totals — underlayment, ice-and-water, drip edge, valley treatment, ventilation, decking allowance, warranty. Cheap usually means less of those, not the same roof for less money.

How quickly will someone call?

Usually within the hour during working hours. If you marked the job as an emergency it goes to the front of the queue and is normally picked up faster than that.

What warranty should I expect?

Ask for both in writing: the material warranty from the manufacturer and the workmanship warranty from the contractor. The second one is the one that matters in year three, and it is only as good as the company behind it.
