According to the National Census of Fatal Occupational Injuries in 2018, roofing fatalities are over ten times the national average. This figure isn’t meant to dissuade you from your roofing project. 

However, it’s important to be aware of the dangers of roofing in order to fully prepare yourself. Here is a brief list of protective equipment we recommend:

  • Work boots that can grip onto the roof well
  • Safety glasses/sunglasses to protect your eyes from stray nails
  • Work gloves
  • Safety vest harnesses for fall protection

How to Install Roof Shingles: One Step at a Time

Before you begin, make sure you have all the supplies that are required. You’ll also want to have your roof assessed beforehand so that you know where to focus your attention. 

Gather Supplies

Once you have your protective equipment in order, you’ll want to gather your supplies for the roof. Along with your roofing nails, step ladders, and asphalt shingles, here are a few more items you’ll need: 

  • Chalk line
  • Tape measure 
  • Claw hammers
  • Utility knife
  • Roofing nailers
  • Rafter square
  • Collated finishing nails
  • Drip edge 
  • Underlayment
  • Staple guns and staples

Make sure all of your tools and materials are ready before you begin the job. Set them aside in a separate bag or a separate section of your garage. 

Prepping the Roof

You’re going to have to prepare your roof before you climb up and start work. You should carry the garbage can to the roof with you or throw down the rusty shingles. However, you’re going to want to make sure you don’t throw away the debris in the place where people are walking.

Use a roofing shovel to clear all the old shingles and a hammer to remove the nails. 

Installing the Underlayment 

Your first move is to extend the roofing underlay around the roof. If you’re not familiar with this stuff, this is what keeps your home isolated from the elements. It’s a kind of weather-proofing that makes it easy for your house to stay cool in the summer and warm in the winter.

Overlap each sheet of underlay by around three to four inches. 

Installing the Flashing

Flashing should be installed anywhere where two roof planes meet, as these areas are more prone to leakage and damage. The flashing serves as an extra protective element in these areas. 

Starting Your Shingles

We’ve come to the toughest part of it now: mounting the shingles. Shingles ought to be mounted on a pre-planned layout and their safety derives from the way they are installed. They’re shielding the roof from water by gravity. Each overlapping shingle should steer the water down and out, away from your roof.

This is where the calculation of the chalk and tape comes in handy. Start at the bottom of the roof and build a template that you can follow with your first shingles. You’re going to want to continue the markings for at least four rows up the roof. 

With your chalk line, you can also use it to create a vertical line every six inches. 

Mastering the Nailing Technique

Nailing your shingles properly is the difference between a roof that can last for years and one that sees damage quickly. After investing in the correct roofing nails and roofing nailer, focus on driving the nail straight down. If you hammer the nail correctly, the top will be flush with the surface of the shingle.

A poorly guided nail is not going to be absolutely flush. Worse, one that has been pushed so hard will produce a slight indentation in the shingle.

Nails also ought to be in the right place. In general, try to have them placed between one inch above the edges and one inch over the edges. The nails that are too high will not protect the shingle underneath. Each shingle, there should be four nails. 

Installing the Shingles

Cut your last shingle to size and nail it into place before starting on the next row. 

Once you get to a ridge at the end of a roof or the drip edge, make sure the ridge is protected as well. Bend the shingle over the ridge so that it’s even and nails both sides in place with two nails. 

Take your time with this process to ensure that your shingles are straight and secured the right way. You can see how neglecting even one shingle can exacerbate water issues even just a year down the road. 

Clean Up

Keep trash cans and push brooms handy so that you’re able to clear up any stray nails on the ground. There may also be other debris in your yard that blew from the roof onto the ground. 

Installing Roof Shingles the Right Way

Preparation is crucial when it comes to learning how to mount roof shingles. You ought to get the right gear in place, too.

Note the shingles are operating by gravity. If you don’t first build the correct standards, the shingles can turn out to be inconsistent. The same is true of your nailing strategy.
