If you want to replace your roof because it no longer functions as it should, then it’s a good idea to learn as much as possible about how your roof works and what you have to ask your contractor before considering investing in a resilient new roof.


The basics of a residential roofing system is simple. Most residential roofs are sloped, meaning that they are designed to have a slope of about 30 to 45 degrees, to allow rainwater to flow down more easily and prevent any issues associated with the impact of hail, thus prolonging the lifespan of your roof.


The roof has an exterior section or layer, which includes its shingles, flashing and other exterior, visible elements such as chimneys and skylights; and an interior area which is designed to support the roof. This layer is formed of elements such as the roof deck – which is the wooden structure that the roof is built on – and the ventilation system, which is designed to prevent heat and moisture from compromising the roof’s overall interior structure.


In most cases, when a roof replacement project is underway, the roofers will only focus on the exterior area, replacing the shingles, flashing and any other elements or upgrades that you might want to focus on. The inner part of the roof will typically be addressed only when there is structural damage that has to be fixed in order for the installation of the roofing shingles to work out properly.  Find more roofing information at
