STEEL ROOFS FAQ

• What are roof safety products?

  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.

  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.

• What is the best time of year to start my roofing project?

  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.

• Is roofing underlay necessary?

  Ruukki always recommends the use of roofing underlay.

• What is the minimum pitch at which a steel roof can be installed?

  The minimum pitch for a steel roof depends on the roofing sheet models.

  For tile sheets, e.g. Monterrey, Adamante, Finnera and Elite, the minimum pitch is 1:4, while for standing seam sheets e.g. Classic it is 1:7.

• How to replace a bitumen felt roof with a steel roof?

  Renovating an old bitumen felt roof with an even surface is easy. Simply change it for a Ruukki steel roof. You can either do it yourself or leave it to the professionals. The following points should be checked to guarantee that you have one thing less to worry about for the rest of your life.

  • Check that the old bitumen felt roof can be used as an underlay.
  • Check the condition of the old felt roof’s supporting structures and battens.
  • Check the diagonal measurements of the old bitumen felt roof. 
  • Check that the ventilation underneath the old bitumen felt roof is sufficient.
  • Carry out all necessary repairs.

  
  

  Steps from an old bitumen felt roof to a new Ruukki steel roof:

  1. Leave the old bitumen felt covering in place.
  2. Fix the vertical battens (min. 32 x 50 mm) at the locations of the roof trusses.
  3. Install the new roofing sheet battens with the right partitioning for the new roofing sheets.
  4. Fasten the new roofing sheets onto the battening boards.
  5. Fasten all accessories (flashings, fillers, rainwater system, roof safety products, lead-ins, etc.).

• Can I install a steel roof profile on any roof shape or are there limitations?

  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.

• What is the correct fall for guttering per metre?

  Ruukki recommends you install gutters so that the fall is approximately 2-3 mm/metre.

• How many downpipes should be connected to my guttering?

  Where the roof pane is less than 10 metres, you can use one downpipe and gutters that fall in the direction of the downpipe. Where the roof pane is more than 10 metres, two downpipes should be used, with the guttering falling in the direction of both downpipes.

• Is it possible to install a new roof myself?

  Ruukki roofs are easy install, so if you are confident you have all the tools and skills necessary for the job, yes, you can do it yourself. However, for more complicated roof shapes and for safety reasons, we do recommend you let professionals take care of the installation.

• What is the correct batten spacing for Monterrey?

  The correct distance from the fascia boards’ outer surface to the middle of the second batten is 300 mm. The distance between the rest of the battening boards is 350 mm.

• When my roof is delivered do I have to take care of storage myself?

  If you have requested delivery of your roof to your premises, you should ensure that you have an appropriate storage space for the time before the roof installation.
  
  Detailed instructions on unloading and storing your roof before installation can be found in the installation instructions for the roofing sheets.

• What is the correct length for roofing sheets?

  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.

• How long does the average roof installation take?

  A roofing installation will generally take anywhere from two days to a few weeks, depending on the size of the project. Although Ruukki roofs can be installed all year round, weather conditions, such as wind, snow and rain, may have an effect on the length of a project.
