Roof Shingling Tips and Tricks
Roof shingling is an easy job to do yourself, especially if you use a few shortcuts that don't compromise the quality of your work. Keep in mind that safety should always be your first priority when it comes to doing any construction work on a roof. With the proper equipment and know-how, you will be able to complete your shingling jobs without wasting money or time.
Shingle Over Shingles
Some professionals will suggest that you not place new shingles over the top of existing shingles. The reason is that asphalt shingles have a lifespan of up to 20 years. Placing multiple layers of shingles will give your roof time to develop problems that can't be easily detected if the roof is stacked with shingles. It is acceptable, however, to add new shingles over existing shingles. The rule is that there should not be more than 3 layers of shingles already placed. While this is a time saving shortcut, it is best practice to strip the roof to inspect for any damaged areas of the roof.
The Best Roof Stripping Tool
On occasion you will see do it yourself roofers armed with a crowbar to strip the shingles from their roof. The best and most convenient tool for this job is called a Roofer's Spade. This tool is very similar to a snow shovel but is out-fitted with teeth or notches in the front of the shovel and a fulcrum underneath. This allows the prying up of the shingles and nails to be much easier than using a crowbar or a regular shovel
Rent a Dumpster
When stripping your roof, there will be lots of debris that will come from atop, including nails. Instead of throwing the loosened shingles and nails into the back of your truck and causing damage, you can call your local equipment rental company and rent a dumpster. This will allow you to throw the debris directly into the dumpster and call the company to pick it up when you are done.
The purpose of underlay is to be that second layer of waterproof and leakage protection on your roof. While many professionals and do it yourself experts will disagree, an underlay is not necessary to install before you add your shingles on your roof. If your shingles are properly installed, you will not have to be concerned with any roof leakage issues. Although adding an underlay of felt has become the industry standard for asphalt shingles, it is not crucially needed.
When you have completely stripped your roof of all shingles, walk the roof again to check for any nails that didn't come up during your initial sweep. Remove them if there are any and prepare your roof for an application of roof guard. Ice guard is waterproof membrane that will help protect your roof from water damage. Ensure you follow the directions of use and application.
Trying to find all the nails that fell from your roof to the ground is an all day job that you don't have time for. To remedy this issue, tie a rope to a bar magnet and drag it along the perimeter of your house. You will pick up all the nails that your eyes could not see.
