The most affordable slate roofing alternative

Inspire roofing is an affordable way of achieving a prestigious outcome and a classical look and feel. With each roofing tile costing less than slate, you can feel comfortable knowing that you’ll be left with a beautiful + durable roof that won’t blow the budget.

Each slate costs just $5.20 + GST


For pitches in excess of 30 degrees, 18 slates will cover each metre of roof. For lower pitches, more slates may be used to ensure better moisture protection. The weight load of Inspire slates is very low e.g. 14kg/m2. The slates have really impressive strength to weigh ratios.

MEASURING UP A ROOF

The number of slates required for a roof is determined by the roof area and the length of the eaves for the “eaves course”.

The area of roof is determined by multiplying the length X diagonal distance to the top x the number of sides or sections. This is explained in the Measuring Guide.

The number of slates required decrease as the pitch of the roof becomes steeper. The roof of a church will typically require 18 slates/m2. A flat roof home will need better coverage to insure total moisture protection e.g. 22 slates/m2

You will notice from the Installation or Fixing Guide (see below) that you need to add slates at the rate of 3.5 slates per lineal metre of the length of all the eaves. This is easily measured and explained with drawings in the downloadable fixing guide.

ROOF PITCHES + SLATE REQUIREMENTS

For battened roofs that are most common in Australia, the minimum roof pitch is 14.5 degrees. Inspire may be used down to 14 degree pitches but only if the roofs are boarded (according to the US manufacturers).

The following table provides guidelines on pitch and gauge in relatively benign wind conditions. Strong winds and rain will require more conservative lapping.

NB. Wastage will be around 5% if hips and valleys are in even proportion but could be as high as 10% for more challenging roofs. 3.5 slates per lineal metre are required for the eaves course. 5.5 ridge caps per lineal metre are required for ridges
