When you’ve finished constructing the walls of your cabin, it’s time to add the roof. Remember to follow the plans in terms of the type of roof that you’ll be adding. You can any type of roof except a flat one. A flat roof doesn’t offer anywhere for water to flow off, which means that you’ll run the risk of building up stagnant water, and this can cause significant damage. A standard hip and gable roof type is the most popular, but with so many to choose from, you can easily construct one that meets your individual style and requirements. From experience, fixing the roof can actually be one of the trickiest elements to complete because it needs to be right to prevent any water leaking in and damaging the interior.
Start by fitting the central roof pillar – this is the main beam that run from one end of the roof to the other. If you’re roof only has a slight slope, then a central beam might not be necessary because the higher external walls will create this for you. If you have hip and gable roof then the central pillar should fit neatly onto the higher sides of each end of the external walls. The central pillar should overhang slightly over the external walls. If it doesn’t, then you run the risk of rainfall causing damage to the outer walls over time.
Once the central pillar is fixed into place, then you can install the outer beams. These will run down from the main pillar and onto the lower external walls. Again these beams should have a slight overhang over the outer walls. Make sure that these beams are evenly spaced out.
If your log cabin will be used for residential purposes, then you’ll need to have insulation, and it’s better to put this in during the roof building process. Fix your internal roof boards and install your insulation materials. By doing it this way you will save time, prevent condensation from forming on the inside of your cabin, and you’ll find that it saves money as well.
Once you’ve completed the insulation and the internal boarding work, you can fix the external roof boards. Fit the main board at the front of the rooftop, arranging it according to the edge of the roof beams. Nail each rooftop board to each rooftop bar and to the side divider as you go. A breathable membrane should be laid over the outer boards for protection before the shingles or other rooftop covering is fitted.
Felt shingles are the easiest to fit, but you can choose any roof covering depending on your requirements. The shingles are attached to the roof boards with nails. Regardless of the type of rooftop covering you have chosen, you should always start from the base edge and work up. Ensure that when using nails to secure the covering in to place, that the nail head lies flush with the top of the covering.
