Where’s the job?

Overview

• Installation of synthetic felt roofing membranes—an efficient, durable and lightweight roofing solution for pitched roofs.

• Skill level: 3 / 5 (basic carpentry skills and an understanding of roofing structure required).

• Typical duration: 1 – 2 days depending on roof size and complexity.

Safety First

• Always use safety harnesses and an appropriate ladder when accessing the roof.

• Wear gloves and eye protection when handling synthetic felt to avoid cuts or irritation.

• Avoid installing during high winds; always plan for calm weather conditions.

• Be cautious of overhead power lines and ensure safe positioning of ladders.

• Ensure all materials are securely fixed to prevent any debris from falling.

Tools & Materials

Step-by-Step

1. Inspect and prepare the roof deck – clean the surface, repair any damage and install roof battens if necessary.

2. Lay an underlay or ice-and-water barrier where required by local building regulations.

3. Unroll the synthetic felt membrane and familiarise yourself with the manufacturer’s guidelines for overlaps.

4. Secure the first row using the appropriate nails or staples, ensuring it lies flat without wrinkles.

5. Overlap each successive row as per manufacturer recommendations, maintaining uniformity throughout.

6. Trim any excess material along the edges with a utility knife for a neat finish.

7. Conduct a thorough inspection for gaps or loose fixings before final sealing is applied.

Completion Checks

• The synthetic felt should lie flat with proper overlaps and no wrinkles.

• All fixings must be secure ensuring the membrane is weather-tight.

• Edges and overlaps are neatly trimmed and sealed.

• Roof drainage is free from obstructions caused by loose material.

When to Call a Pro Instead

If the installation involves complex roof geometries, steep pitches or requires structural repairs, it is advisable to engage a professional roofer to ensure compliance with building regulations and manufacturer warranties.
