About this deal
Once you have added the shingles to both slopes of your roof, you should be ready to apply to ridge detail. For this task, you can use traditional shingles cut to shape or a shingle ridge roll. Felt Roof Ridge
Felt is an extremely lightweight material, which means it can be used on a number of weaker and less structurally sound buildings, such as garden sheds and outbuildings without any concerns that it will be too heavy. Easy to installNext, measure the surface of the shed roofing to calculate how much felt you’ll need – don’t forget to add an extra 5-7.5cm for overlaps at the edges and the gables. Generally, if felting a pitched shed roof you’ll require 3 pieces of felt – 1 for each side and then one to overlap the two edges, but this may vary depending on the size of the shed roof and the width of the felt rolls. 3. Lay the first piece of felt Then fit your shingle underlay onto the exposed roof. Ensure that your underlay extends beyond the edges of the roof by around 50mm. The underlay will be applied in strips, with each strip overlapping the previous one by at least 75mm. Then turn down the edges and nail it at 500mm centres. Preparing The Roof For Felt Shingles At the corners of the roof, cut the roofing shingles to create an overlap when Folded around the corner, then nail this into position. Fixing The Felt Shingles in Place Lay the first length of the shed roof felt across the bottom part of the shed roof, ensuring the overhang is there, before nailing the top edge of the felt with galvanised nails. Try to achieve an even gap of around 50cm between each nail. Then fold the edges of the felt around the edges of the roof and nail them into place. 4. Lay the second piece of felt Installation advice on installation of IKO shingles from a practical point of view: https://www.tuin.co.uk/blog/fitting-felt-shingles-for-log-cabins/
Generally we do not see the need for the placement of a membrane (roofing felt or IKO underlay for all garden buildings as it is not generally necessary for leisure buildings and has not been recommended for over 15 years. To set the first row of shingles you will need to trim some material from one edge of the shingle strip before fixing them at the eaves. With the square butt shingles, this should be 125mm. Or if using fishscale shingles, trim off 100mm. You’ll need to do this for all odd-numbered rows.Next, lay the second layer of felt on the roof. Ensure any joins on the first layer are overlapped, and any air bubbles have been smoothed out, and then nail it down as before. 8. Spread adhesive Continue this process until one side of the shed has been completed, and then repeat on the other side. 7. Add a capping sheet
