Three questions about your home

Up to three local contractors, and never more.

Step 1 of 6

What best describes your home?

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

Free. You are not committing to anything.

01

Are you a roofing company?

No. Old Mill Roofing Co. of Corona is a free matching service. We do not hold a roofing licence, we do not employ crews, and we never come to your house. We pass your request to independent local contractors who do the work and who you hire directly.

02

Is this really free?

Yes. You pay nothing, now or later. Roofing contractors pay us for the introduction, which is why the service costs you nothing and why we are upfront that it is how we make money.

03

How long should a roof last here?

Rated life and real life are different numbers. Here, ordinary rated life is a fair guide, provided the attic breathes. Ventilation and the quality of the installation move that more than the brand does.

04

How much deposit is normal?

Ten to thirty per cent is ordinary, and is often used to order material. A demand for full payment up front is a reason to walk away.

05

Do you cover the whole Riverside County area?

Yes. The contractors we match on cover Corona and the surrounding towns, so if you are just outside the city limits it still works.

06

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.

07

Can I stay in the house while it is done?

Most people do. Expect noise from early morning, dust in the attic, and a day where the driveway belongs to the crew.

08

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.

09

Are gutters included in a re-roof?

Normally a separate line. It is the one add-on that genuinely costs less when done at the same time.

10

Should I take the cheapest quote?

Only if it is the same roof. Most large gaps between quotes are scope gaps. Ask the cheapest contractor which of the other quotes items they have left out, and why.

11

Can I just put a new roof over the old one?

Codes in most places allow two layers. That does not make it wise. You lose the chance to see the deck, and the next roofer has twice as much to remove.

12

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.

13

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.

14

I have solar panels. What happens to them?

Panels have to be detached and reset. Budget for it separately and coordinate the two trades. Never put a new solar array on a roof with under ten years left.

15

What does a new roof cost in Corona?

For a typical Corona home of about 24 squares, an architectural asphalt re-roof usually lands between $12,500 and $28,500. 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.
