GAF Timberline HDZ and UHDZ look almost identical at first glance.
They aren't the same shingle. As GAF Master Elite contractors, we install HDZ as our standard, but UHDZ brings real upgrades, extra thickness, a stronger algae warranty, that matter for some homeowners. Here's the real difference between the two, so you know exactly what you're paying for either way.
GAF Timberline HDZ vs. GAF Timberline UHDZ Roof Shingles
GAF Timberline shingles are known for their durability and dimensional architectural look, ideal for Myrtle Beach’s extreme weather conditions.
At Linta Roofing, we frequently install GAF Timberline HDZ shingles because they provide excellent warranties at a reasonable price. However, GAF Timberline UHDZ shingles introduce key improvements that may make them more suitable for some homeowners. The UHDZ model has a thicker, more dimensional look due to enhanced shading, making it appear 20% thicker than the HDZ. Additionally, the UHDZ includes an increased algae warranty, adding even more long-term protection for your roof.
