Frequently Asked Questions

Buying roofing materials can be daunting, especially when ordering them online. With over 40 years of experience in roofing, however, we get asked lots of questions about our range of roof membranes. Here are some of the most common questions with answers for each!

Why Do I Need a Roof Membrane?

When using metal or plastic roof tiles, it is essential that your roof space is well ventilated. A failure to do so could result in moisture building up. This will impact the effectiveness of your loft insulation and, in severe cases, result in timber rotting.

Membranes protect your loft space by allowing water vapour to escape more easily. You will typically use this in partnership with ridge and eave vents for maximum air flow. Some roof membranes also prevent other roofing issues, such as tile uplift caused by severe winds.

Do I Use a Membrane with Roofing Sheets?

Yes, in some cases you may be required to use a breathable membrane with roofing sheets. This is particularly the case on larger projects, such as a home or office. Simply refer to the manufacturer’s guide, which will often recommend the most suitable membrane for that particular roofing sheet.

Can I Use a Roof Membrane on a Boarded Loft Space?

Yes, membranes can be used on both rafters and boarded roofs. This is as moisture can build up on both roof types when metal or plastic roof tiles are used.  Simply ensure that you refer to the manufacturer’s guide, as installation methods may vary on different roof types.

How Else Can I Ventilate My Roof?

As outlined in our guide to roof ventilation, there are numerous ways you can improve the ventilation of your loft space. This is primarily through the use of a breathable membrane and eave vents. In some circumstances, you may also benefit from the use of ridge ventilation.
