What's the Best Flashing For A Low Pitched Extension Roof?

Water is one of the biggest threats to a property; you can often identify the early signs of water damage when materials start to warp, sag, buckle and change colour.

Too much water in the wrong place can also lead to mould growth and structural damage, which can damage the environment that you live in and your health. 

In order to prevent moisture getting into a property in the wrong places, a number of materials are used during construction that are designed to prevent water ingress.

One of these materials is flashing – a construction essential when building an extension. If you’re wondering ‘what's the best flashing for a low pitch extension roof?’, then read on to discover the answer… 

What Is Flashing?

Flashing is an impervious material that forms an incredibly important part of a roofing structure, as well as the structure of many other parts of your home. 

Normally made from lead, aluminium or copper, flashing has the main purpose of redirecting water away from vulnerable parts of your roof or walls.

Depending on the type of flashing chosen, the flashing can be concealed or exposed, these types of flashing form the main two categories. 

On the roof, installing flashing will help to prevent water ingress, particularly around the joints in the roof. Without flashing installed, the roof is very vulnerable to water damage and water will likely start to seep into the loft space, or in the case of a single-storey extension, into the living space.

This type of flashing can also be used to help prevent water infiltration in conservatory extensions but is only one part of good conservatory moisture protection. 

Choosing the Right Flashing for a Low Pitch Extension

There are a large number of different flashing types that are all designed for different purposes. Some of the main types of flashing, include:

•    Apron Flashing
•    Valley Flashing
•    Chimney Flashing
•    Through-Wall Flashing
•    Sill Flashing
•    Step Flashing

For the most part, these different types of flashing are not interchangeable, so it’s essential that the correct type of flashing is chosen.

For a low pitch roof that is abutting a wall, step flashing is usually the best option. This is a non-continuous type of flashing that’s fitted to work with the slope of the roof.

With step flashing, the multiple sheets of flashing provide a safety net, so if one piece of flashing stops working, the next piece of flashing will still help to protect the roof from water ingress. 

A step flashing can be used on most pitched roofs, but for a low pitch roof, the flashing installed may need to be slightly wider than normal.

Constructed to prevent 90% of heat loss, this innovative insulation material regulates the temperature inside of a conservatory to further help prevent condensation problems and make the environment useable all year round

Protecting Your Conservatory from Moisture Damage

Insulation is a great investment to protect your property from moisture infiltration. In solid roofed extensions, a material like closed cell spray foam can be used to create a water-deflective layer, as well as insulate the interior from heat loss.

For conservatries, one of the best protective insulation materials that you can invest in is multi-foil insulation. Multi-foil insulation is excellent for reducing the risk of moisture from condensation, as it has a great vapour control layer.
