All Weather Roof Coating: Repair or Replace?
If your roof is showing signs of wear, small cracks, blistering, or general weathering, it can be tempting to start pricing up a full roof replacement. But before you dive into a costly and time-consuming renovation, it’s worth asking: is an all weather roof coating a smarter, easier solution?
At FixTrade.co.uk, we supply trusted, trade-quality roofing products like Sika Black Jack 905 All Weather Roof Coating, designed specifically to offer durable, fast-drying protection without the need for a full roof replacement. In many cases, a high-performance coating is all you need to extend the life of your roof and protect your property, without breaking the bank.
All Weather Roof Coating: How It Works and When It Makes Sense
All weather roof coating is exactly what it sounds like: a protective, waterproof compound applied directly to your roof surface to seal out moisture and protect against harsh conditions. Our most popular solution, the Sika Black Jack 905, is a fibre-reinforced bitumen coating that brushes on easily and dries rapidly to a tough, black waterproof seal. It’s specifically designed for:
• Felt, asphalt and bitumen roofs
• Gutters (non-plastic)
• Metal or structural steel roofing
• General-purpose waterproofing jobs
But how do you know if it’s right for your roof?
Signs Your Roof Needs Attention
Small Cracks or Splits in Roofing Felt
These can appear due to UV exposure or age. If the damage hasn’t compromised the underlying structure, a coating like Sika 905 can seal the area, reinforcing the surface and preventing further deterioration.
Blistering or Bubbling
This is often caused by trapped moisture or heat and may look concerning, but as long as the layers underneath are sound, applying an all weather roof coating will help stabilise the surface and block out further water ingress.
Fading or Chalky Appearance
Weathered roofs often lose their colour or feel brittle to the touch. This is usually a sign that the waterproofing layer has degraded. A coating can restore the protection without needing to strip and replace the entire surface.
Minor Leaks or Damp Patches
For isolated leaks, particularly around joins, flashing, or old repair areas, a fibre-reinforced bitumen coating is an ideal DIY fix, providing instant resistance to wash-off by rain and forming a flexible seal.
If you’re seeing any of the above, coating your roof may be the quickest and most cost-effective way to restore protection.
When Should You Consider Replacing Instead of Repairing?
While Sika 905 All Weather Roof Coating is incredibly versatile, there are some situations where a full replacement might be necessary:
• Widespread rot or sagging of timber beneath the roof
• Large sections of missing or heavily damaged felt
• Persistent internal water damage that reappears after repairs
• Structural movement or deformation of the roofline
If you're unsure, we always recommend speaking to a roofing specialist before committing to a full replacement. But for many property owners, especially DIYers managing small to mid-sized issues, our coating is more than up to the task.
