At SJ Roofing Ltd, we have over 30 years of experience in the business.  Our local family firm was established in 1992, but prior to that we did our time as roofers. You’ll find us friendly to deal with, but we take roofing seriously.

We know that your roof is the first barrier against the elements.  A sound roof protects your home or business from all four seasons here in Wellington.

We pride ourselves on our craftsmanship and attention to detail.  We will even advocate for you – we’ve been known to go into bat for customers who have been let down by less trustworthy contractors and cowboys.  We are members of the Roofing Association of New Zealand and our work is guaranteed.  From the initial consultation through to leaving your site clean and tidy, we know you’ll be delighted working with us.

Let’s talk.  We’ll explain things in Plain English – we love simple solutions.

We are Licensed Building Practitioners

 If you are doing work around your home, you need to check if the work is restricted.  If so, you will need a licensed building practitioner.

What is a licensed building practitioner (LBP)?
LBPs are designers, carpenters, brick and blocklayers, roofers, external plasterers, site and foundations specialists who have been assessed to be competent to carry out work essential to a residential building’s structure or weathertightness. (business.govt.nz)

S J Roofing are specialist Butynol suppliers and are Ardex approved applicators.

Ardex Butynol is a butyl rubber waterproofing membrane engineered for roofs, decks and water containment. It is BRANZ appraised and is an E2/AS1 acceptable solution.

It’s renowned for its strength, versatility and watertightness. It has a long, proud history and an unmatched record of success in the waterproofing industry.

Butynol® is a synthetic rubber membrane which resists ageing from: – heat
– sunlight
– ozone

It is proven the world over to provide a durable, extremely long-lasting roofing system with the flexibility to conform to the shape of virtually any roofing profile. It has excellent gas impermeability and toughness and remains flexible at low temperatures.

Regardless of whether it’s laid on a high pitched roof with a good run off or a flat roof subject to periodic ponding, Butynol® will protect against water. Because it has a potable water certificate it can be used on roofs that feed water tanks used for drinking water.

Ardex recommend that the membrane should always be fixed by approved Applicators like SJ Roofing because we have been specially trained and are experienced in various application methods.

Butynol has been appraised and approved by BRANZ for use in New Zealand. It’s also the only butyl product manufactured in New Zealand.
