Laying roofing felt correctly is a fundamental step in weatherproofing a structure, particularly for pitched roofs such as those found on sheds. The proper application ensures durability and protection against the elements.
Essential Steps for Laying Roofing Felt
The process primarily involves covering the main side sections of the roof, followed by securely capping the ridge.
- Prepare the Side Sections: Begin by taking a piece of roofing felt for one side of the roof. Position it carefully, ensuring it extends from the eave up towards the apex of the roof.
- Ensure Flatness and Security: Once positioned, press the felt down firmly across the entire surface. It is crucial that the felt lies completely flat against the roof deck, without any wrinkles or air pockets, for optimal performance.
- Nail Down the Sides: Secure the felt to the roof using roofing nails. Start nailing just below the apex and work your way downwards towards the eave. Maintain consistent spacing, nailing at approximately 100mm intervals along the entire length of the felt. Repeat this precise process for the opposite side section of the roof, ensuring both sides are securely fastened and perfectly flat.
- Cover the Ridge: After both side sections are fully installed and secured, apply the final, third piece of felt directly along the roof's ridge. This piece typically overlaps the top edges of the two side sections, providing a waterproof cap for the highest point of the roof and sealing the apex.
Important Considerations for Installation
- Flatness is Key: Always prioritize pressing the felt down firmly and ensuring it is completely flat. This prevents water pooling and significantly extends the life of the felt by ensuring proper drainage.
- Consistent Nailing: Adhering to the recommended 100mm nailing intervals provides robust attachment, preventing the felt from lifting or tearing in windy conditions and ensuring long-term stability.
- Working Downwards: Starting the nailing process from just below the apex and moving down helps to smooth out the felt and prevent trapped air, leading to a neater, more professional, and ultimately more effective finish.
Following these detailed steps will ensure your roofing felt is laid correctly, providing effective and long-lasting protection for your structure.
