Metal Tile Overlay Re-Roofing Waikato
Qualified Metal Tile Roofing solutions for Hamilton and the wider Waikato region.
Fully Guaranteed Workmanship
Every roof we install is backed by our 10-year workmanship guarantee and covered under manufacturer warranties. We follow all safety protocols, communicate clearly, and take pride in doing things right the first time.
RANZ Member – Roofing Work You Can Trust
As a proud member of the Roofing Association of New Zealand (RANZ), Riggall Roofing meets the highest industry standards in every reroofing project we take on.
Whether you’re replacing a roof on your family home or upgrading an older investment property, you can trust that your reroof will be handled with care, quality, and integrity from start to finish.
Replace Your Roof with Style and Strength
At Riggall Roofing, we specialise in replacing aging or damaged tile roofs with Gerard® metal tiles—a lightweight, durable solution that offers the traditional tiled look with the strength of modern steel.
If your home has Decramastic tiles, Shingles or asbestos, we can install new metal tiles directly over the existing roof using Gerard’s concealed fastening system. This BRANZ-approved method reduces disruption, avoids costly asbestos removal, and ensures your home stays dry and secure during the process.
You’ll still receive full product and workmanship warranties, and your roof will meet or exceed all New Zealand Building Code requirements.
Our skilled, LBP-qualified team completes every re-roof with precision and care—delivering a high-quality, long-lasting finish you can trust.
Cf Technology provides the ultimate in weather tightness and style
This innovative product range means that every tile is booked into the next tile and the fasteners are completely concealed and protected from the elements, leading to a streamlined appearance.
Ideal for a Range of Roof Types
Metal tile re-roofing is perfect for:
Homes with aging or damaged Decramastic tile roofs
Roofs with asbestos (overlay options available)
Homeowners wanting to retain a tiled look
Cover old or damaged shingle tiles
Character-style homes
