- Remove any existing fascia boards Remove the fascia boards and the old felt if you’re re-felting.
- Measure the shed roof Measure the roof, taking into account that you should leave around 50mm for overlaps at the eaves and 75mm at the gable ends. You’ll probably need 3 pieces of felt, but some smaller sheds only need 2.
- Apply felt to the roof Once you’ve cut the felt to size, apply the each piece to the roof, pulling it tight. Then nail along the length of the roof at 100mm intervals. For nails at the bottom edge, they can be wider – around 300mm. If you’re adding a piece of felt in the middle of the shed along the apex, fix it using adhesive, then nail it at the lower edge at 50mm intervals.
- Tidy up the overhangs Fold down the felt at each overhang and nail it securely. Cut a slit in the overhang at the apex using a pen knife, then fold that down and nail at 100mm intervals along the gable. If you like, you can add fascia boards to keep the shed looking neat. Use wood nails to secure them and then trim away any excess felt.

Garden Sheds in Portstewart
Garden sheds are a significant factor of any useful garden space. They provide storage for heavy garden tools, as well as for other equipment. A large shed may provide enough room for plant potting or a general workshop. Alternatively, a substantial shed could be utilised as an inside seating area. Garden sheds come in a huge range of sizes and can be specified to your particular requirements, giving you full control over the amount and position of windows, type, size and location of door, and design of roof. Garden sheds generally are available in one of three materials. Wooden sheds are the classic design and can be integrated well into any garden creating a natural look, especially if the wood used for the shed is matched to bordering fences. Wooden sheds remain very popular, although they will demand maintenance by retreating or staining the wood to protect the lifespan of the shed. Garden sheds are also constructed from metal, which is very tough and therefore ideal for storage of tools and other equipment. Metal sheds also require hardly any maintenance. The final material for garden sheds is plastic, which in modern examples is a lot more durable than might be expected. When contemplating a garden shed, it's critical to ensure that you select one that will fit in your garden space. Garden sheds should be placed on a flat area, and will require a base to be built as a foundation. This base could be produced from either concrete, paving, gravel or a floating wooden base, but will have to be the right size for your shed and capable of supporting the weight of your shed when loaded.

FAQs
- Mark out the area and dig the top layer of soil, trying to get the ground as flat as possible.
- Build a timber frame to size.
- Measure out 4 rows of 3 blocks to create good weight distribution and lay in place.
- Underneath each block, dig around 50mm wider than the blocks and about 150mm deep. Fill the hole with pea gravel until it’s flat.
- Place timber planks along the rows of blocks and see how level it is. Add or remove blocks where necessary. If it’s only a small difference, use shingle underneath the timber until it’s level.
- Nail your timber shed base to the timber planks to create a sturdy base for your shed.
Yes, your shed does need a base. This is to give it a solid, level foundation. Open soil will not help with the longevity of the shed itself or the contents within. The best materials to use to make your shed base are concrete, natural stone or wood.
