  • Type of felt chosen: (Torch-on felt lasts longer but costs more.)
  • Ease of access: (If hard to reach, labour costs could rise slightly.)
  • Whether you add insulation: (Good for reducing garage condensation.)

🔵 Other Important Points:

  • Torch-on felt is recommended in 2025 for most single garages — it offers 20+ years of life if installed properly.
  • Basic felt might last 10–15 years but will cost a little less upfront.
  • If new fascia boards or drip edges are needed, they might add £50–£150 to the final price.
  • Scaffolding is usually not needed for a single garage unless it’s in a tight or raised location.

In short:

👉 For a single garage roof in Crawley in 2025, you should expect to pay around £600 – £1,500 depending on the system, condition, and upgrades chosen.

ServicePrice Range (approx.)

  • Whether you want insulation or new trims added

Frequently Asked Questions About Garage Roof Refelting

How much does it cost to refelt a single-car garage roof?
The typical cost to refelt a standard single-car garage roof in Crawley, Sussex, or Surrey ranges between £600 – £1,500. The final price depends on the size of the roof, the type of felt used (torch-on felt, cold-applied felt, etc.), and whether any structural repairs are needed before the new felt is installed.

How long does it take to refelt a garage roof?
Most garage roof refelting jobs are completed in one day, especially for a standard single-car garage size. If additional work is required, it could include repairing the roof decking. Replacing rotted timber might also be necessary. The job could take a little longer. At Find My Roofer, we always aim to complete the work efficiently without compromising on quality.

How long does a felt garage roof last?
A newly refelted garage roof can last between 10 to 20 years. The lifespan depends on the quality of the felt used and the installation. We recommend using torch-on felt systems for longer durability. These systems can often offer warranties of up to 20 years when installed by professionals like Find My Roofer.

What are the signs my garage roof needs refelting?
Common signs that your garage roof needs refelting include leaks or sagging. You may also notice blistered or cracked felt. Look for visible holes or tears. Moss growth and damp patches inside the garage are also indicators. If you notice any of these issues, it’s best to contact Find My Roofer. Get a professional assessment as soon as possible.

Can you replace damaged roof decking during the refelting process?
Yes! At Find My Roofer, we offer full repair services if your garage roof’s timber decking is damaged. Before applying new felt, we inspect the structure thoroughly. We replace any rotten, broken, or unsafe sections. This ensures a solid, watertight finish that will last for many years.
