Repair costs can range from £50 to £500 or more, depending on the work required.

Guttering and Fascia Repairs

While refelting, roofers might identify issues with the guttering or fascia that also need addressing. These repairs can add to the overall cost.

Guttering and fascia repairs can range from £50 to £300 or more, depending on the extent of the work.

Waste Disposal

Old felt and any debris generated during the work will need to be disposed of. This is usually included in the roofer's quote, but it's worth checking to ensure you're not hit with any unexpected charges.

Waste disposal costs are typically around £50-£100, but this can vary depending on your location and the amount of waste generated.

Choosing the Right Roofer

When considering the cost of refelting a dormer roof, it's crucial to choose a reputable, experienced roofer. While it might be tempting to opt for the cheapest quote, this isn't always the best approach. A professional roofer will ensure the work is done correctly, safely, and to a high standard.

Get Multiple Quotes

Getting quotes from several roofers will give you a good idea of the average cost and help you identify any outliers that might be too good to be true. Be sure to compare like-for-like quotes, as some roofers may include additional services in their price.

It's also a good idea to ask for references and check online reviews to ensure you're choosing a reliable roofer.

Check for Guarantees and Warranties

Many roofers offer guarantees or warranties on their work. This can give you peace of mind and protect you against any issues that might arise after the work is completed.

Guarantees can range from one year to 20 years or more, so it's worth asking about this when you're getting quotes.

In conclusion, the cost of refelting a dormer roof can vary significantly depending on several factors. It's essential to understand these factors and choose a reputable roofer to ensure you get a high-quality, durable result. Don't forget to factor in additional costs such as repairs and waste disposal. Regular maintenance and timely refelting can extend the life of your dormer roof, saving you money in the long run.
