Our standard roof shingles are 400mm long and come in widths of 75, 100, 150 and 200mm wide. This is for a basic roof covering with an appealing look. We also offer 450mm or even 500mm lengths, depending on the level of cover required – we usually recommend 1/2 cover for open-sided structures and 1/3 cover for homes and sheds.

Shingles are available in two basic styles – tapered or flat. These are cut to length depending on the application. Please note that we are one of the only companies in the UK cutting shingles from scratch, which enables us to advise on many different options.

The terms “half coverage” and “third coverage” refer to the amount

of surface area on a roof that is covered by individual shingles. These measurements are typically used to describe the exposure or reveal of each shingle in relation to the total surface area they cover. Here’s an explanation of each:

**1. Half Coverage Shingles:**
In roofing terminology, “half coverage” implies that when the shingles are installed, approximately half of each shingle’s width is covered by the one above it. This overlapping arrangement creates a more substantial coverage and provides additional protection against the elements. Half coverage shingles are common in various roofing styles and contribute to a traditional, classic aesthetic.

**2. Third Coverage Shingles:**
On the other hand, “third coverage” means that each row of shingles covers about two thirds of the length of the shingle beneath it. This arrangement allows for less exposure of the shingle surface and often results in a more textured and varied appearance on the roof. Third coverage shingles are sometimes used to create a distinct visual pattern and can contribute to a more modern or rustic look.

In summary, the key difference lies in the amount of overlap between adjacent rows of shingles. Half coverage provides more coverage and a smoother appearance, while third coverage allows for less exposure, resulting in a potentially more textured and visually dynamic roof surface. The choice between these styles often depends on the desired aesthetic and architectural preferences of the homeowner or the specific design requirements for a given project.

Also, there is a difference in how water tight each is. Third cover is generally regarded as professional roof style and will be more or less 100% watertight, whereas half cover is an aesthetic cover which will potentially have some small leakage… generally used for open structures, gazebos etc where it’s not critical…

We have developed a further half way house option with our offerings, and that is to have 200mm showing of a 450mm tile .
