A beginner’s guide to roof sealing

At times, we can be a little ungrateful for our roofs. They protect us from howling winds, clattering hailstones and many other myriad threats from above, yet we’re rarely in a rush to fix them.

The first thing we would want when facing the elements is a roof over our heads – but can you give a roof a roof over its head? As it turns out, kind of.


Though we most commonly use sealants for smaller jobs, like fixing cracks or preventing leaks in sinks, a new practice has been discovered that makes maximal use of the waterproofing, heat-resistant qualities of sealants. You guessed it – roof sealing.

Roof sealing is a meticulous process. Not quite as precise as hand-sealing every line at a snail’s pace, but precise enough that a non-professional can quickly cause your roof problems. Even the smallest of gaps in a sealing process can cause leaks, and seeking professional insight and services, such as those found at https://www.ct1.com/product-applications/ct1-the-ultimate-roof-sealant/, is vital.


A silicone roof sealant, when properly applied, will provide an impermeable yet breathable surface, one that deflects rain whilst simultaneously allowing moisture from the home to pass through. The added UV protection of silicone helps to drastically slow down the molecular degradation of your roof, providing a sunscreen-like layer to the top of your house.

In the long run, your roof will last longer against the elements and be far less brittle, keeping it stronger for longer.

Some other benefits include fire resistance and the prevention of mould growth, further increasing the safety and hygiene of your home as secondary benefits. The same impermeable property that prevents rain from getting in also prevents moisture from being trapped, significantly reducing the probability of mould build-up.

Roof sealants can also lower the temperature of your house, keeping your upper floors cooler during the summer months. Although this was originally considered an environmental advantage too, scientific evidence doesn’t exactly support the claim – your house gets cooler, but the heat that would’ve been absorbed doesn’t just disappear either. Regardless, your home will benefit from the sealant.
