Roofs can account for a lot of heat loss, so if you’re converting your garage, it’s important to ensure it is well insulated. In most cases, garage roofs use a flat roof construction. In this article, we’ll look at how to properly insulate these roofs.Â
How to assess the condition of your garage roof?
In most cases, garages feature flat roofs. Despite their name, virtually all flat roofs will have a very low pitch (less than 10º) to ensure that rain and snow run off and drain away. If the roof has been fitted with an insufficient pitch or has bowed over time, this can lead to water ponding, potentially damaging the roof structure. If water ponding is occurring, there will usually either be standing water on the roof or clear staining patches where water has gathered and evaporated.Â
In addition to issues with water ponding, you should also check the roof surface and guttering are clear of debris and that the existing waterproofing system is in good condition. Keep an eye out for any damage or tears in the waterproofing or signs of bubbling under the surface, which can be a sign that water has entered the construction and evaporated. You should also check the fascia boards and gutters to ensure there are no leaks or signs of damage or rotting.Â
If issues are present, you will need to strip the roof and address these before fitting any insulation. Whilst this may be time consuming, it will also ensure the roof performs well for years to come.Â
