Garden Sheds in Thornhill

1. Remove any existing fascia boards Remove the fascia boards and the old felt if you’re re-felting.
2. 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.
3. 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.
4. 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.

1. Remove fascias and trims Unscrew or prise off the screws and nails fixing the trims and fascias to your shed.
2. Take off doors and remove windows Unscrew hinges from doors and take them off. Remove all metalwork once the door is off. If you’ve got frames on your windows, unscrew these, and remove the panes. Be extra careful if your windows are made of glass.
3. Take off the roof Prise off the tacks from the roofing felt and take the felt off – you can’t reuse it, so you’ll need to throw it away. Unscrew the screws on the roof boards and slide them off the shed’s frame – you might need a friend to help you do this.
4. Take out the roof brace (optional) If your roof has a brace, unscrew the brackets that hold it to the side of the shed. Remember not to lean on anything once you’ve taken the brace off as the walls might be wobbly.
5. Unscrew the frame from the floor Remove all the screws that are holding the shed to the base, remembering not to lean on the walls.
6. Unscrew the frame corners Starting at the corner of the front gable, remove the screws where the panels meet. Once a panel is free, lift it carefully out of the way so you can carry on with the others.

1. How to build a shed base out of paving slabs
   • Mix sand and cement together to make mortar or use a pre-mixed one
   • Use a trowel to lay mortar for 1 slab at a time on the sub-base and lift a damp-sided slab onto the mortar, using a piece of timber and club hammer to tap the slab into position carefully. Continue to lay the first row of slabs
   • Make equally-sized spacers in all the joints in the slabs to ensure they’re the same size, checking it’s level as you go along
   • Next lay slabs along the two adjacent outer edges, filling in the central area row by row
   • Leave the mortar to set according to the instructions or for at least 48 hours before filling in the joints with mortar or paving grout
2. Building a shed base from concrete
   • Create a wooden frame around your shed base area (also called formwork) to stop the concrete from spreading
   • Mix pre-mixed concrete with water or use 1 part cement to 5 parts ballast
   • Wet the sub-base using a watering can with a rose on the end
   • Pour the concrete onto the framed base starting in one corner
   • Push the blade of a shovel up and down in the edges of the concrete to get rid of air bubbles
   • Use a rake to spread the concrete, leaving it around 18mm higher than the top of the frame. Work in sections of around 1-1.m²
   • Compact the concrete using a straight piece of timber that’s longer than the width of the base. Move the timber along the site, hitting it along at about half of its thickness at a time until the surface is evenly ridged
   • Remove excess concrete and level the surface by sliding the timber back and forwards from the edge that you started. Fill in any depressions and repeat until even
   • Run an edging trowel along the frame to round off exposed edges of the concrete and prevent chipping
   • Cover the concrete with a plastic sheet raised on wooden supports to allow slow drying. Weigh it down with bricks
   • Once the concrete is set, you can install your shed and remove the wooden frame with a crowbar

Try to put your shed in open space, away from trees, bushes and other buildings. This will help to protect it from falling branches and sap. It will also mean that you can access all sides of the shed for repair and maintenance purposes. Make sure you take a look at garden shed planning rules before you pick a final spot for your shed.
