Expect damage to roofs.

That’s what the Weather Service warning says when golf-ball hail is coming. We’re the Arvada roofers who come after it. We inspect for free and chalk a test square on every slope. Then we meet your adjuster on the roof.

Was your street under it?

Radar tracks every hailstorm that crosses the Front Range. Before we set up a ladder, we pull the hail swath for your address. It tells you the date of loss and the size of the hail your roof took. That date goes on your claim.

Concept demo: whatever you enter, this plays an example storm over an example street. Nothing is looked up or sent.

Next, the roof. On every slope, the adjuster chalks a square of 100 sq ft and circles each hail hit inside it. Many insurers replace a slope at eight to ten hits. Drag the square to find the worst of it.

Drag the square over the roof.

The claim, day by day.

Most hail claims on the Front Range close in about six weeks. Here’s who does what, and when.

  1. Day 0

    The storm

    Stay off the roof. If it’s safe, photograph a few hailstones next to a golf ball before they melt. Write down the date and time. That’s your date of loss.

    Lumpy hailstones on a wet lawn around a golf ball; the biggest are as large as the ball or larger
    Golf-ball hail is 1.75″. That’s the size that breaks shingles.
  2. Day 1 to 3

    The inspection

    We chalk a square on every slope and photograph every hit. Then we check the soft metals: gutters, vents, window screens and the fins on your air conditioner. Dents there tell the adjuster how big the hail was.

  3. Day 3

    You file

    You call your insurer with the date of loss. We send you the photos and a written report to attach. We don’t file for you, and we don’t talk to your insurer without you.

  4. Day 10 or so

    The adjuster

    We meet your adjuster on the roof and go slope by slope together, square by square. Most disagreements end right there.

  5. Day 20 or so

    Approval

    Your insurer sends the scope of loss. You pay your deductible and nothing more. Colorado law bars any roofer from paying or waiving it. Be wary of anyone who offers.

  6. Day 30 or so

    The new roof

    Tear-off and new roof in one day on most houses. We sweep the yard with a magnet for nails and send the final photos to your insurer.

  7. Day 45

    The next storm

    Your insurer gets the final invoice and releases the depreciation it held back. The claim closes. The next rain runs straight off.

    Rain on new shingles, the next storm.

What goes back on.

On the Front Range we put back roofs rated for hail. Class 4 means the shingle took a 2″ steel ball dropped from 20 ft, twice on the same spot, without cracking. Many Colorado insurers take money off your premium for it. Ask yours.

Hail sizes drawn to scale, from pea (0.25 inch) to baseball (2.75 inches). The June storm dropped golf-ball hail, 1.75 inches; the Class 4 test uses a 2 inch steel ball. 0.25″pea 0.75″penny 1.00″quarter 1.25″half dollar 1.50″walnut This storm 1.75″golf ball Class 4 test ball 2.00″hen egg 2.50″tennis ball 2.75″baseball Hail sizes drawn to scale, from pea (0.25 inch) to baseball (2.75 inches).

We live under the same hail.

Cinderpeak is fourteen roofers from Arvada. When a storm comes through, we’re out checking our own roofs too.

  • We don’t knock on doors after a storm.
  • We don’t take a deposit on insurance work.
  • You sign nothing until your insurer approves the claim.
  • The person who chalks your roof comes back the day it goes on.
