The best ways to waterproof your roof

Waterproofing is a key part of any roof maintenance. Whether you’re planning a flat roof extension with a lantern or getting recurring property leaks, consider how weatherproof your roof is. Unfortunately, when wet weather hits, it can expose how vulnerable our roofing is, providing a stark reminder of the importance of fast roof repairs.

Here are some of our top tips for keeping your roof watertight.

How do you know if your roof isn’t waterproofed?

A well-waterproofed roof will stop rain from getting into your property, so if this isn’t happening, you’ll soon start to see issues. A typical sign of a poorly waterproofed roof is recurring property leaks. These may present as drips through your ceiling or skylights, mould and damp in your attic, or even watermarks down your walls.

Waterproofing issues can be caused by lead flashing deterioration around areas such as chimney stacks and dormer windows. Leaks may also be the result of unresolved guttering problems.

What’s the best waterproofing method for leaky roofs?

One of the best upgrades for a leaky roof is GRP fibreglass. This is a type of liquid roofing made from a fluid-based polymer containing glass fibres, applied to various materials such as metal roofing, concrete and felt to help it become as watertight as possible.

The cold liquid application of fibreglass forms a waterproof membrane across your roof. It completely seals joints while remaining flexible to changing weather. GRP fibreglass roofs are also used for walk-on areas like balconies and roof gardens.

What is EPDM roofing?

A popular alternative to GRP fibreglass is rubber roofing, which creates an ultra-strong membrane (so it’s also a great option if you want something more watertight). Certain products are stronger than others, so always ask your roofing contractor about what they’d recommend.

EPDM is also chosen for its algae resistance, fast application and seamless finish, making it a popular option for anyone looking to improve their flat roof’s waterproofing.

Should you get a roof inspection?

We’ve said it here many times before, but early identification of all types of roofing issues is how you ensure minor concerns don’t turn into costly headaches. This is particularly true of waterproofing problems, in which water ingress can do untold damage to your roof and home from both inside and out.

If you want your roof to remain as waterproof as possible, book regular inspections with a reliable roofer. They can spot problems before they occur, informing you of any repairs required. They’ll also thoroughly check your roofline for areas which are vulnerable to water damage, including your gutters.
