Roof flashing is an essential component of any roofing system, designed to protect against water penetration and damage to the structure. Lead-free roof flashing installation has become increasingly important in recent years due to concerns about the environmental impact of lead and its potential health risks.

This article will provide you with a comprehensive guide to expert techniques for lead-free roof flashing installation using QACO-FLEX, a modified polyethylene compound reinforced with aluminium mesh.

What Is Lead-Free Roof Flashing?

Lead-Free Roof Flashing refers to roof flashing materials that do not contain lead. Lead was once a popular material for roof flashing due to its durability and ability to withstand harsh weather conditions. However, the environmental and health risks associated with lead have led to a shift towards lead-free alternatives like QACO-FLEX.

QACO-FLEX Lead-Free Roof Flashing Installation

The installation process for lead-free roof flashing with QACO-FLEX is relatively straightforward and can be completed by roofers with all types of experience levels. The following is a step-by-step guide to the lead-free roof flashing installation process:

Preparing the Roof Surface:

The first step in the Lead-Free Roof Flashing Installation process is to prepare the roof surface. This involves cleaning the area around the penetration, removing any old flashing or debris, and ensuring that the surface is level and free of any sharp edges.

Measuring and Cutting the QACO-FLEX to Size:

The next step is to measure and cut the QACO-FLEX to the proper size. It is important to measure accurately to ensure that the QACO-FLEX fits appropriately and provides adequate protection.

Installing the QACO-FLEX Roof Flashing:

Once the QACO-FLEX has been cut to size, it can be installed around the penetration. The flashing should be installed in such a way as to create a water-tight seal, with the edges overlapped and the seams sealed to prevent water from penetrating.

Sealing the Edges:

After installing the QACO-FLEX, the edges should be sealed to prevent water from infiltrating the roof. A suitable sealant can be used to achieve this, and it is essential to ensure that the edges are properly sealed to prevent water from seeping in.

Checking for Proper Installation:

Once the installation process is complete, it is vital to inspect the lead-free roof flashing to ensure that it has been installed correctly. Check for proper sealing and straightness of the flashing and ensure no gaps or seams may allow water to penetrate.

Is lead-free roof flashing installation difficult?

The lead-free roof flashing installation process with QACO-FLEX is relatively straightforward and can be completed by roofers with all types of experience levels.

Can you use QACO-FLEX to fix existing faulty/leaking lead flashing?

Yes, QACO-FLEX can be used to fix existing faulty/leaking lead flashing by lifting the lead and installing QACO-FLEX underneath it in full 5m lengths. The lead can then be dressed down over the QACO-FLEX as an over-flashing or trimmed back for a smaller over-flashing. If the lead is completely removed, QACO-FLEX can be chased back into the brickwork, have an over-flashing or be installed underneath the facia.

Do you need any specialist tools to install QACO-FLEX?

Installing QACO-FLEX does not require any tools and can be done by hand. The best way to dress the material is by using both thumbs. It can stretch up to 50% in length, allowing for installation around 360 degrees, but stretching is not necessary during installation.
