MK Roofing Ltd is a family-run roofing company based at 18 Osborne Street in Waltham, Christchurch, led by director Mike Keast and backed by close to two decades in the trade. The team works to a simple set of core values — integrity, quality, delivery and honesty — and sums up its reputation in plain terms: you call, they show up.
Services span the full life of a roof: new installations and full replacements, protective colour coatings as a cost-effective alternative to re-roofing, seamless membrane systems carrying a 15-year warranty, and repairs and maintenance across all roof types, with quick response for urgent damage — especially in winter. Free quotes and competitive pricing are standard.
The crew includes executive assistant and office manager Emily Garlick, sales representative Vickie Mulder, and roofers Michael Curwood, Josh Whataiwi Gowans Kotara and Carlos Caro. MK Roofing now also serves Queenstown, Wānaka and Cromwell through a dedicated Central Lakes team, holds Licensed Building Practitioner credentials, SiteWise Gold (assessment score 94) and SiteSafe membership, and donates to Hagar New Zealand from every job completed.
At 18 Osborne Street in Waltham, Christchurch, MK Roofing runs a family-operated roofing company led by director Mike Keast, who credits the business with "a remarkable 19 years of experience" across every aspect of the trade. The tagline — Quality That's Through The Roof — is matched by four core values the team leans on daily: integrity, quality, delivery and honesty.
Mike sums up the working style in one line: "Trust needs to be built. You call, we show up. Our word is our reputation." That ethos has a community side too — from every job completed, MK Roofing donates to Hagar New Zealand, which supports people who have survived slavery, trafficking and severe abuse.
The service list covers the full life of a roof. Installation and replacement starts with an assessment of your needs and guidance on materials, then delivers a precise, weather-resistant, structurally sound result. For roofs that are tired but not finished, protective colour coatings are a cost-effective alternative: resilient paint that shields against weather, UV rays and pollutants, applied with meticulous preparation and a wide colour choice.
Seamless membrane systems give commercial and residential buildings a durable, watertight, low-maintenance surface backed by a 15-year warranty. Repairs and maintenance cover all roof types, and the team flags quick response for urgent damage — especially in winter, when a small leak can become a big one.
Across every job the same pillars apply: skilled roofers with pride in detail, quality materials built to last year-round, competitive pricing and prompt answers to questions. Free estimates are the standard starting point.
It's a genuinely family-feel crew. Emily Garlick, executive assistant and office manager, brings 15 years of customer-service experience. Sales representative Vickie Mulder carries 25 years in construction, including 15 as an architectural technical representative. On the tools, Michael Curwood is a membrane specialist with around two decades in roofing; Josh Whataiwi Gowans Kotara is an efficient planner known for high standards; and Carlos Caro adds more than 20 years of construction experience from Argentina, spanning painting as well as roofing.
MK Roofing's footprint recently stretched beyond Canterbury into the Central Lakes district, with a dedicated team serving Queenstown, Wānaka and Cromwell under regional manager Ben Thompson — same standards, same certifications, same service guarantees as the Christchurch operation.
Central Otago gets its own respect. The region spans NZS 3604 snow zones N1 to N4, exposed lakeside sites regularly fall into High or Very High wind zones, and daily temperature swings of 25°C stress fixings and sealants. The answer is specification: correct fixing patterns and batten spacing for the snow load, stepped-up edge fixings, flashing overlaps and underlay for the wind, and clip-fixed tray systems where expansion cycles demand them.
The profile the team specs most often in the Lakes is the Dimond Heritage Tray — a hidden-fix tray with clean, modern lines suited to alpine architecture, available in Colorsteel Endura and Maxx, with long-run pans that reduce end-laps and leak risk. Christchurch residents may have spotted it on the Halswell Library. An online Alpine Roof Spec Tool narrows the right spec to your site in three questions.
Reviews circle the same themes: clear communication, jobs finished in good time, and results that lift a home's look and value. One client credited Mike with excellent communication throughout her roof project; others praise professional service from the first phone call and thorough repairs and maintenance.
The entry point is a free quote — call 0800 705 805 or email [email protected]. Hours are Monday to Friday, 8:00 am to 6:00 pm. Credentials are checkable too: the company works as Licensed Building Practitioners, holds SiteWise Gold with an assessment score of 94, and is a SiteSafe member.
Whether it's a winter leak in Waltham or a new alpine build above Queenstown, the pitch stays the same: honest advice, quality materials and workmanship that outlasts the weather.
