Step-by-Step Installation Instructions
Now that you have prepared the necessary materials and ensured safety, it’s time to dive into the installation process for GAF Timberline HDZ shingles.
Step 1: Remove Existing Roofing
If you are replacing an old roof, start by removing the existing shingles and underlayment. Be sure to check for any damage to the roof deck and replace any rotted or compromised sections.
Step 2: Install Underlayment
Once the old roofing is removed, install a high-quality underlayment to protect against moisture. Follow these instructions:
- Begin at the eaves of the roof and roll out the underlayment horizontally.
- Overlap each row by at least 6 inches to ensure proper waterproofing.
- Secure the underlayment with roofing nails, placing them approximately every 12 inches along the top edge.
Step 3: Install Starter Strip Shingles
The next step is to install starter strip shingles along the eaves:
- Cut the starter strip shingles to fit the length of your eaves.
- Position the starter strip so that it overhangs the edge of the roof by about 1/4 inch.
- Nail the starter strip in place, ensuring it is secure and flat against the underlayment.
Step 4: Install Timberline HDZ Shingles
With the starter strip in place, you can now begin installing the Timberline HDZ shingles:
- Start at the bottom corner of the roof and work your way across, ensuring the shingles are level.
- Each shingle should be staggered with the previous row to enhance the roof's waterproofing capabilities.
- Nail each shingle in place using four nails per shingle, placing them just above the adhesive strip.
- Use a chalk line to ensure straight rows and maintain consistency.
Step 5: Cut Shingles for Valleys and Roof Features
When working around valleys, chimneys, or vents, you may need to cut shingles to fit properly:
- Measure and mark where cuts are needed.
- Use a utility knife to carefully cut the shingles, ensuring clean edges.
- Install flashing where necessary, using roofing cement to seal any gaps.
Step 6: Install Ridge Cap Shingles
To finish the roof, you will need to install ridge cap shingles:
- Cut Timberline HDZ shingles into thirds to create ridge caps.
- Install them over the ridge of the roof, ensuring they overlap each other.
- Nail the ridge caps securely, using roofing cement to seal the edges if needed.
