Before replacing a roof, you may need to remove old fiberglass shingles. This process will require some additional laborers in order to completely remove the old material.
Ensure all safety precautions are observed when performing this type of work, particularly since you will be working off the ground. Working carefully and deliberately will reduce accidents and keep everyone safe.
Step 1: Remove Shingles from the Roof
Once you have climbed upon the roof, remove the old fiberglass shingles using the scraper tool. This tool is designed to remove the shingles and the nails holding the shingles into place on the roof.
Placing the tool underneath the shingles, lift upwards to separate from the roof. The shingles will tear away in sections. Toss or carry the debris pile to the side of the house where the dumpster was delivered. Continue to work to remove the shingles, starting from the bottom and moving to the left and up.
Step 2: Remove Scrap Debris and Loose Nails
There will be scrap material and loose roofing nails still intact after the roof has been scrapped. You will need to remove this material by hand, using the claw hammer.
Remove any roofing nails that are exposed or sticking up through the roof, along with any remaining scrap debris. Nails that you are unable to remove can be hammered down. Use new nails to secure the roof. Remove bad roof sections and replace with the plywood lumber. Use 4 inch screws to secure the lumber to the roof studs.
Inspect the entire roof area and make sure that all loose debris is removed and any nail heads that are exposed are pulled up or nailed flat. If there is any debris left and not removed before the new roof is laid, it could be a source for leaking later on.
Step 3: Remove the Debris
Most municipalities and localities permit you to rent large dumpsters. The cost varies by location but this is an investment that is well worth the cost. It is much easier to throw the roofing debris into the dumpster as you work then come back after the fact and have to pick pieces of roofing material out of plants and flower beds.
Watch out for rusty nails or any sharp debris that may cause cuts or tetanus. If you do cut yourself, have the wound treated immediately in order to avoid infection.
