Choosing the right product
Most roof installations usually take place during the spring/summer, making it the busiest time of the year for roof projects. This might make it difficult to fit your schedule in with that of the installer.
However, there are no technical limitations to completing your roof installation at any time throughout the year. So you can schedule your project for a time that is most suitable for you.
Ruukki’s selection of steel roofs is extensive and you can find all the colours available from product section on this website.
Remember, however, to check with your local building authority regarding any limitations on roof building, shapes and colours.
Confirm your choice of colour with our one of our dealers, who will be happy to discuss your decision with you.
Ruukki offers a range of roof safety products, including snow stops, ladders and roof bridges.
The legal requirements concerning roof safety products depend on the country in which you live.
Contact your nearest local dealer and ask about the legal requirements.
Installation tips
The correct length of a roofing sheet is measured from the outer surface of the farthest facing board at the eaves to the middle of the ridge. In order to get the correct measurements for your order, it is recommended you check the measurements of all roof panels in different places.
Note that roofing sheets are installed so that the length of the roofing sheet over the eaves is approximately 40–45 mm. This means that at the ridge there is enough space for ventilation.
Detailed instructions on unloading and storing your roof before installation can be found in the installation instructions for the roofing sheets.
Steel roof profiles can be installed on most roof shapes.
Some complicated roof shapes, such as arches, can be challenging for profile installation. Also, if the roof pitch is close to being flat, certain products might not be suitable.
A machine-seamed roof might be more suitable for more challenging roof shapes.
If you have any questions concerning the shape of your roof, just contact our Technical support.
