Are You Thinking About An Extension?

Do You Want A House Extension?

James Roofing know about roofing in Liverpool. The post below details a few types that are commonly used.

Roofs form a large proportion of the cost of an extension, particularly if it is a pitched roof, which is why a lot of people go for the cheaper option of a flat roof. But flat roofs don’t last as long and are prone to developing leaks that are hard to fix, as water ‘pools’ on the surface. They also don’t tend to blend in with the rest of the house particularly well, unless the property has flat roofs throughout.

Translucent Flat Roofs

A flat roof can be fitted very quickly though, because as soon as the supporting timbers are in place, the roofing material can be attached. If a transparent or translucent roof is required, glass could be laid, with supporting frames, but corrugated plastic or flat multi-walled polycarbonate is more likely.

The multi-walled products are layers of clear polycarbonate sheet separated by longitudinal ribs of the same material. This versatile material can be cut to size onsite and the number of layers goes from two to seven, with different finishes that affect the heat and sound insulating properties of the roof.

Guttering

As roofers it’s logical that we also provide a guttering Liverpool based service. You should consider this when deciding on any extension or the type of roof you feel would be appropriate to your build.

Opaque Materials

If the roof doesn’t need to let light in, then corrugated sheet metal, plastic or fibreglass is cheap and cheerful and can be found in a wide variety of colours. The plastic versions do degrade over time though, and you need to be careful to drill holes for the fixings because punching them through is likely to crack the sheet.

A more long-lasting covering is felt waterproofed with bitumen. This is more expensive as it cannot be laid over the roof timber, so a supporting layer of sheet timber such as plywood of MDF needs to be laid down first. There are newer products on the market that look similar to felt but claim better performance, longer life and resistance to leaks.

Many home extensions these days are conservatories or other buildings with a lot of glazing, but brick built (or stone) is still popular, for a number of good reasons. But how do brick built extensions differ from glazed buildings and why should you pick one? Note that for the purposes of this article the phrase ‘brick built’ will refer to any outer material such as brick, stone, flint or any other, as opposed to a double-glazed construction such as a conservatory.
