How To Install Bitumen Roof Shingles 

Installing a new roof or replacing an old one is a significant investment for any homeowner. One popular roofing material choice is bitumen roof shingles, also known as asphalt shingles. Bitumen shingles are durable, affordable, and offer excellent protection against the elements. If you’re considering installing bitumen roof shingles yourself for House renovation, this step-by-step guide will walk you through the process.

Safety Precautions:

Before you begin, it’s crucial to prioritize safety. Ensure you have the necessary safety equipment, including a safety harness, gloves, safety glasses, and a stable ladder. Always work with a partner, as roofing can be physically demanding and potentially hazardous.

Gather the Required Materials:

To install bitumen roof shingles, gather the following materials:

  • Bitumen roof shingles
  • Underlayment (typically felt or synthetic)
  • Roofing nails
  • Roofing adhesive
  • Drip edge
  • Flashing
  • Roofing cement
  • Utility knife
  • Hammer
  • Chalk line
  • Tape measure

Prepare the Roof:

Start by preparing the roof for the installation process. Remove any existing shingles, nails, and debris. Inspect the roof for damage and make necessary repairs before proceeding. Ensure that the roof surface is clean, dry, and free of any loose or damaged materials.

Install Underlayment:

Underlayment acts as an additional layer of protection between the shingles and the roof deck. Begin at the bottom edge of the roof and roll out the underlayment horizontally, overlapping each row by a few inches. Secure the underlayment with roofing nails or staples, ensuring it lays flat and smooth across the entire roof surface.

Install Drip Edge and Flashing:

Next, install the drip edge along the eaves of the roof. Nail it in place, ensuring it overhangs the roof’s edge slightly. Flashing should be installed around chimneys, vents, and any other roof protrusions to prevent water leakage. Secure the flashing with roofing cement and nails for a watertight seal.

Determine the Starting Point:

To achieve a visually appealing finish, it’s important to determine the starting point for the shingle installation. Measure the width of a full shingle and subtract the exposure you want between the shingles. Divide the remaining measurement by two to determine the offset from the centerline of the roof. Use a chalk line to mark the starting line accordingly.

Install the Starter Course:

The starter course provides a solid base for the first row of shingles. Lay the starter course shingles upside down, with the tabs facing up. Secure them along the chalk line with roofing nails, ensuring they overhang the edge of the roof. Trim the last shingle to fit if necessary.

Install the Shingles:

Begin installing the shingles from the bottom row, working your way up the roof. Position each shingle so that it overlaps the previous one and aligns with the chalk line. Use roofing nails to secure each shingle, placing them in the designated nail strip just above the shingle’s adhesive strip. Continue this process until you reach the top of the roof.

Trim Shingles:

As you approach roof protrusions, vents, and edges, you’ll need to trim the shingles to fit properly. Use a utility knife to cut the shingles to the desired shape and size, ensuring a snug fit around these obstacles. Take care not to cut into the roofing material underneath.

Ridge Cap Installation:

Finally, install the ridge caps to provide a finished appearance and protect the roof’s peak. Cut the ridge caps into individual shingles, ensuring they cover the peak while overlapping each other. Use roofing nails and roofing cement to secure the ridge caps in place.

The Bottom Line!

Installing bitumen roof shingles can be a rewarding DIY project for homeowners looking to enhance the protection and aesthetics of their homes. By following this step-by-step guide, you can confidently install bitumen roof shingles, adding value and longevity to your roof. 
Remember to prioritize safety, take your time during the installation process, and consult professionals like BUON Construction for help if needed. A properly installed bitumen roof will offer years of durability, weather resistance, and peace of mind.
