A steel installation is always a good option for your roof, it really is worth the investment if you can afford it. This blog will address the accessories or options you should consider, there are three important additional options to consider beyond profile, style, venting options, colour and gauge (thickness of the steel).
Strapping – it isn’t necessary to strap all roofs prior to installation. Strapping improves the overall performance and longevity of your steel roof as it provides air circulation between the roof deck and roof material but it isn’t always necessary and could be an eliminated option if the budget is tight. Some steel roof profiles are designed to allow air flow to pass under the roof panels. Generally the lower the profile the more likely you will need strapping.
Snowstops or snowguards – our opinion at Roofing for Less is that you ALWAYS need snowstops and they should be made of steel that is 26 gauge or lower, any higher gauge and they won’t stand up to winter conditions. In our service areas of Orillia, Barrie, Midland, Gravenhurst, Bracebridge, Huntsville, Simcoe, Muskoka and Georgian Bay this option is extremely important with the amounts of snow and ice that come off of a steel roof. If snow and ice accumulate it will come off the roof in an avalanche not only making it dangerous for exit and entry to the home but it can cause damage to things on the roof such as vents and chimney stacks and to things on the ground – cars, decks, furniture or anything within 15 feet of the perimeter of the house. In 99% of our installations we install steel snowstops in the same colour as your steel roof product. The plastic snowstops do not stand up over time and eventually become brittle and turn yellow. In most cases we custom bend the snowstops in varying lengths and install them in a staggered pattern, we can also order 10 foot lengths from the manufacturers but not all roofs require 10 foot lengths everywhere then we usually end up cutting them down anyway – cost is about the same either way.
Eavestroughs and strapping of eavestroughs – the main function of eavestroughs is to divert water away from the foundation of your home so pretty much every home should have eavestroughs and even more so with a steel roof as the water cascades down the roof line at a much faster pace than with a shingle roof and can cause a waterfall effect resulting is rapid and deep water accumulation right next to your foundation. If you have a very steep pitched long lined roof eavestroughs may not be an option as the snow load will almost certainly rip the troughs off each winter regardless if snowstops are in place or not. If you have eavestroughs and a steel roof we recommend strapping them to the roof (not the fascia board). The straps should be placed no more than two feet apart to be effective. The strap is fixed to the roof and wraps around the outside of the trough, up and behind and attached at the other end to the roof. Generally we make our own straps and use the same colour as the eavestrough. Strapping significantly reduces the chances of the eavestroughs being torn off by sliding snow and ice.
