If you notice that your roof is missing some shingles or some parts of it are cracked or damaged, then you know you have to replace them. This is a job though that would entail some preparation. It’s not just going to your roof, prying the old asphalt roofing shingles and hammering in new ones. Any self respecting DIY guy, and maybe a friend or two, will be able to get the job done easily.
First off, you need to know how many supplies you will need. Measure the area where you will replace the asphalt roofing shingles. You need to understand that shingles are typically sold in square pieces covering a one hundred square foot area. So what you need to do is to measure the length and the width, then add about ten percent for accidental wasting of shingles. Divide this by 100 and you will get the number of asphalt roofing shingles to purchase.
From there you will be able them to measure how many roofing felt to purchase, basing it on the fact that each shingle measures 36 inches by 12 inches, and the number of roofing nails needed. (Each asphalt roofing shingle uses about two and a half pounds of roofing nails.)
From there, you will now be able to use a square headed roofing shovel to pry loose old and damaged asphalt roofing shingles. Make sure to check whether the roofing support is still in good condition. If there are rotten roofing supports, be sure to replace them.
And that’s it, just make sure to follow the manufacturer’s manual of instructions and you can have a great looking and durable roof in no time at all.
