Asphalt shingles last a long time, and if installed properly, will effectively protect your home against water leaks. Installing asphalt shingles may appear complicated at first glance, but if you are good at following directions, you can do the job on your own and get good results. To install asphalt shingles, follow the steps outlined below.  

Step 1 – Get Ready To Work

Gather all the materials you need to install your asphalt shingles, and put them inside a utility box. Once you have all your tools and materials ready, take out your ladder and set it on solid ground before you use it to climb up your roof.

Take out your rope then tie one of it on the handle of the utility box. Take the other end of the rope with you as you climb up the ladder to your roof. Once you are on the roof, hoist the utility box up by pulling on the rope.

Step 2 – Install the Drip Edges and Waterproofing Underlay

Line the eaves with the drip edges then lay down the self-adhesive and waterproof underlay over the whole roof area. This will serve as the shield to keep water from seeping into your home. Then, lay the felt underlay. Allow 3-inches overlap between each section, to allow complete coverage even with displacement. Install 1 on top of the other, with the higher section always on top. Install the rake drip edge at the sides. Staple the felt underlay under each rake drip edge and drip edges.

Step 3 – Locate Starting Point Then Install the Asphalt Shingles

Snap the chalk line at the top center of the roof towards the eave. This will serve as guide to start installing the shingles. Use the shingle guide provided along with the shingle packaging, starting from the center line towards the rakes of the roof.

First, install the starter strip of the shingles, using self-sealing adhesive along the eave. Let 3/8 inch of its portion overhang beyond the edge, for dripping. This should prevent letting water seep in. Nail the shingles on top of the first line, flush off the starter course. If you are in a windy area, use 6 nails per shingle. Otherwise, you can use 4 nails per shingle. As soon as the course in laid, snap again chalk lines, this time to align horizontally across the roof, for the succeeding lines of shingles down to the eaves. Allow 5 inches of each bottom edge to overlay the course below it.

Step 4 – Finishing Up

Clean up the area, and remove all loose materials to prevent accidents. Lower the utility box back to the ground, then climb down the ladder. Fold the ladder and store it in a safe place, away from the reach of young children. Put away all useful materials you have left, for future use.
