Step 1 of 6

What best describes your home?

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

No cost to you. Contractors pay us, you do not.

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.

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

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.

Coatings can buy a sound roof several years. Coating a failed roof buys you a wet roof with a fresh top coat on it.

Locally

Behind it: shaded slopes that never really dry out. Nothing dramatic happens. A slope stays damp most mornings for thirty years, and eventually that is enough.

About flat roofing here

What does a new roof cost in Rancho Palos Verdes?

For a typical Rancho Palos Verdes home of about 24 squares, an architectural asphalt re-roof usually lands between $13,500 and $27,500. Tile, slate and standing-seam metal run well above that. The number moves on how many old layers come off, how much decking is soft underneath, and how easily a truck can get to the house.

Do you handle commercial buildings?

Yes. Commercial requests go to contractors who do low-slope and flat systems rather than to residential crews. Say so on the property question and it routes correctly.

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.

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.

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