Shingling a roof is easy if you have the necessary knowledge on how to do it. Here is some useful information on how to shingle your roof using asphalt shingles.
Your primary concern while shingling a roof should be your safety as you will be working at considerable heights. So, make sure you are safe from all falling hazards. The next step, deck preparation, is when you make sure your deck is smooth, dry, and free of any holes or gaps and appropriately fastened to the roof trusses.
Work your way from the bottom of the roof to the top while installing asphalt shingles. The first material installed at the eaves is the drip edge. Once that is finished, a thin, self-adhering membrane called ice water protector is installed to prevent it from harsh cold weather and rains.
The third step is to install a roof underlayment. This can either be synthetic roof underlayment or an asphalt-saturated felt. Next, cover the joints and valleys in your roof so that no leakage occurs. For this, you may need to flash certain areas with an extra layer of water-shedding stuff to keep the water off the roof. Once all of that is finished, begin laying the shingles.
Most building structures allow two layers of asphalt shingles on their roofs with a 4/12 pitch or less. On steeper roofs, you can put up to three layers.
Yes, if you have used asphalt shingles and they are in pretty good condition, you can re-roof it. However, you can’t do this with wood or slate roofs.
Reshingling a roof is not hard if you have only a small area to cover, the right tools, and the slope of the roof is manageable. However, it’s best to call professional roofing contractors to do the job for you as it will require hard work.
If your roof is showing signs of curling or missing shingles, missing granules, moss, it’s time to reshingle it.
On average, an asphalt shingle roof will last 15 to 25 years before requiring replacement.
