Here’s a comprehensive guide to assist you through hiring a roofing contractor and planning a roof replacement:
Preliminary Planning
- Inspect your current roof (look for leaks, missing tiles, sagging).
- Determine your budget (include contingency of 10–15%).
- Decide on roofing material (e.g. slate, tile, metal, flat system).
- Research local regulations and planning permissions.
- Schedule work for a season with stable weather.
Finding the Right Contractor
- Get 3 written quotes from local, well-reviewed contractors.
- Confirm they are licensed, insured, and accredited (e.g., NFRC, Construction Online, CHAS – Dobson Roofing have all of these.).
- Ask for references and check previous work or reviews.
- Verify if they offer manufacturer-backed warranties (on both materials and labour).
- Ensure they will obtain permits and follow building regs.
Ask if scaffolding, waste removal, and clean-up are included.
Before Signing a Contract Check if Contract Includes:
- Full scope of work
- Materials to be used (with brand/specs)
- Start and finish dates
- Total cost (with payment schedule)
- Warranty details (duration, what’s covered)
- Agree on how unforeseen repairs (e.g., rotted decking) will be handled.
- Get everything in writing —no verbal promises only.
During the Project
- Check that proper underlayment and battens are installed.
- Ensure ventilation and insulation are addressed.
- Confirm leadwork/flashing is installed at junctions and chimneys.
- Stay in regular communication with the project lead.
- Keep records and take progress photos if possible.
After Completion
- Inspect the finished roof thoroughly.
- Ensure all debris and old material is removed.
- Get a completion certificate (especially if building control was notified).
- Receive final invoice and confirm warranty documents are issued.
- Leave a review or referral if satisfied. See below for our Google Reviews:
