Hardie Trim

Maintaining Correct Roofline Clearance with Superior Remodelers

James Hardie is the superior exterior siding brand, covering 8 million homes and counting, but its performance depends on proper installation. The team at Superior Remodelers meticulously follows the Installation Best Practices Guide to ensure your siding benefits fully from Hardie’s 30-year warranty.

Roofline clearance is a crucial aspect of proper installation due to the volume of water running down a sloped roof. At the roof-to-sidewall junction, a self-healing adhesive-backed membrane must be installed before the flashing, followed by 16 oz. copper step flashing at every shingle course and kickout flashing to deflect water away from the siding. This process ensures the roofline to sidewall intersection is 100% waterproofed, preventing premature failure of your James Hardie siding.

Without proper installation practices, your brand-new James Hardie siding will fail prematurely, wasting your investment. Here are some of the Hardie roofline fails we have encountered over the years:


Common Roofline Clearance Issues

Example 1:

This homeowner hired a different contractor to install James Hardie clapboard six years prior to our visit. The siding had completely failed, with the ColorPlus finish deteriorating. Proper roofline clearance was not maintained, leading to water damage and premature failure.

Example 2:

Here, step flashing is present but not adequate. The Hardie siding began to fail because the roofline clearance must be 2 inches wide and continuous across the entire roof to sidewall area. At Superior Remodelers, we ensure all roof to sidewall junctions have a 2-inch strip of aluminum, protecting your siding from premature failure.

Example 3:

This case shows a complete lack of roofline flashing, causing the first two courses of Hardie siding to fail at the bottom of the roofline. Without correction, this failure would continue up the entire roof to sidewall junction.
