This project shows the steps for replacing an asphalt shingle roof that was damaged in a hail storm. These best practices will show you what to ask for and to know if the roofing contractor is doing a quality job. In this project series, the roofing contractor work crew is followed through the full sequence of tearing off the old shingles and installing the new roof.

New Roofing Materials

The roofing contractor ordered the new roofing materials as specified in the contract from a roofing supply company. The roofing materials were delivered on a flatbed tractor trailer and the pallets were unloaded with a Moffett truck mounted forklift. The truck driver normally would have set all the pallets in the driveway, but I asked him to set several in the yard so as not to block the garage door.

The roofing contractor placed an order with a dumpster company for a 3 axle trailer to haul off the old shingles and other debris. I requested a dumpster trailer on tires (as opposed to steel rollers) so it wouldn’t scratch the concrete driveway. The dumpster was completely full by the end of the roof replacement job.

I chose the GAF roofing products for my roof. The GAF Pro-Start™ Eave/Rake Starter Strip and GAF TimberTex® Ridge Cap Shingles wrapped up on a pallet:

The new architectural shingles are GAF Timberline® HD™ Lifetime High Definition® Shingles with a “Lifetime” warranty.

Below are boxes and rolls of GAF Shingle-Mate®, Cobra® Rigid Vent 3™ and StormGuard® Leak Barrier (peel & stick ice and water shield). The GAF Shingle-Mate (black rolls in the photo) are fiberglass reinforced roof felt that is superior to standard 30 lb felt.

Hail Damaged Roof Replacement: Part 1 – Materials & Tear Off

Old Asphalt Shingle Roof Tear-Off

The old hail damaged asphalt shingle roof is torn off and tossed to the ground. Patio furniture, plants and other breakable items are moved out of the way. Sheets of OSB are laid against the house to protect the lower windows. The roofing crew also protected the outdoor air conditioning units with OSB sheets nailed together in an A-frame configuration so as not to block the air flow. A large tarp covers the porch to catch the debris and nails.

An interesting thing was the roofing crew stacked the torn off shingles in neat piles to carry off to the dumpster.

More shingles and OSB roof deck taken off to be hauled away. These sheets of OSB decking were removed because the box vents will not be replaced since I have ridge vents. Notice the square cutouts for the box vents in the deck sheets.

The following is the old shingle roof tear-off process on Day 2 of the job. The roofing crew worked on the roof in sections, tearing off and installing only what they could finish in a single day, “buttoning up” the roof at the end of each day so it was watertight in case an unexpected rain shower.

The roofing crew used specialized shingle tear off shovelsto pry up and rake off the old shingles, roof felt and nails.

A laddervator is a cool device if you’ve never seen one. A small gas or electric motor operates a cable & pulley system on a specialized ladder to lift bundles of shingles, rolls of roof felt and other supplies to the roof. A huge labor-saver.
