Techniques to Attach a Patio Roof

There are several methods of attaching a patio roof to an existing roof among which some ways are:

  • Directly Fix The Back Channel: In this process, you will have to strengthen the fascia and back channel via reinforcing the 2 rafters inside the roof. The step will be very easy and simple. However, It will not let you go low or high.
  • Make the roof higher: You will have to take out the house gutter and put the back channel slightly higher so you can make the patio roof higher. Once you remove the gutter, you can install transfer flashing to the patio from the roof. It will let you add around a 100 mm of additional height or more.
  • Install Some Riser Brackets: If you’d like to reach a particular height, you can raise the roof of the patio using riser brackets. The raised roof with the brackets would require a custom barge cap. Not only it will let you lift the ceiling up to 2ft, but offer different options for the finishing look as well. If you want to get some natural light, then opting for opaque twin wall sheeting will be great. Because, this will let natural light pass through to give you splendid view.
  • Let The Air Flow While Blocking Elements: The ultimate purpose of attaching a patio roof is that it keeps you from sunrays and rain. Sadly, it also tends to end up blocking the airflow sometimes. To let the air circulate and avoid the rain splash, you have to put the patio sheeting over the roof top of about 300mm so it can provide you with a barrier from the water without blocking air circulation. 
  • Get the cleanest look: The people who want a clean and clear look  might go for this one. Just by attaching the patio and the back channel directly to the wall, you can get the cleanest look. Not only look, but also you will get better protection from rain.
  • Lift The Roof By 500mm: Lift the roof up to 500mm by taking out the gutter, fascia and eaves. The back channel should be directly connected to the rafter and then strengthened. This technique will provide you with a clean finish connected to the wall line.
