Testing Method
We used a sharpened screwdriver to remove the caulk from the screws. We performed three tests: removing caulk from standard roofing screws, removing caulk from roofing nails, and removing caulk from roofing screws with zinc-plated heads.
For each test, we installed the caulk and allowed it to cure for 24 hours. We used a utility knife to cut the caulk along the length of the screw, and then removed the excess with a putty knife. We removed the caulk surrounding the nail with an X-acto knife and pulled out the remaining caulk with a pair of pliers. We then removed the caulk from the heads of the screws by hand.
We found that most of the caulk removers performed well on all three types of screws, with few major differences between them. The main difference was that the removers containing acetone, such as the ones we tested from 3M and The Home Depot, soaked in more deeply than other types. Since acetone is a polar solvent, it dissolves materials by drawing out their moisture. The Home Depot’s product soaked in so deeply that it took a lot of digging to remove all the residue.
In general, we found that for most jobs, any of these products would work well.

How Do You Seal Screw Holes in a Metal Roof?
One of the best ways to seal screw holes in a metal roof is to use a product such as roof sealant or a metal-specific caulking. This product is designed to provide a waterproof seal that can withstand the elements and protect the roof from further damage. Before applying the sealant, make sure to clean the roof surface thoroughly and remove any rust or dirt that may be present.
Once the surface is clear, apply the sealant to the screw holes in a thin layer, making sure that the sealant is evenly distributed around the hole. Allow the sealant to dry for a few hours before checking for any signs of leakage. If any is present, apply an additional layer of sealant and let dry before proceeding.
When the sealant is dry, the screw holes should be adequately sealed and the metal roof should be protected from further damage.
Should I Seal Metal Roof Screws?
It is important to properly seal metal roof screws to ensure the longevity and performance of the roof. When screws become loose, it can cause significant damage to the roof and make it more susceptible to water damage. To prevent this, the screws should be tightened and then sealed with a sealant.
