Factors affecting the synthetic slate roof cost

Here’s the list of worthwhile considerations that can impact the end cost of a synthetic slate roofing project. 

  • Roof structure. The size and complexity of the roof impact the cost of manufacturing materials as well as the cost of installation. After all, installing a larger and more complex roof requires more time, qualification, and labor.
  • Roof pitch. The pitch or slope of the roof can also influence installation costs. For example, opting for a steeper roof pitch may necessitate additional safety measures and specific expertise, which instantly raises the price by $7.000 - $20.000.
  • Roof permits. Depending on local regulations, a homeowner may need a permit to install a new roof. The permit fee varies from $150 to $500, depending on the location.
  • Roof tear-off. When the existing roof is in poor condition, it must be removed before the synthetic slate is put in. This service increases the project cost by $1 to $5 per square foot.
  • Underlayment. A particular type of underlayment, which may be asphalt-saturated felt, rubberized asphalt, or non-bitumen synthetics, and its quality can affect the installation cost by adding $0.42 - $0.47 per square foot to it. 
  • Roof decking. The condition of the roof decking or sheathing, which are wooden boards that make up the foundation of the entire roof, is also crucial. Additional repairs might be necessary, and you should expect to spend $2 - $5 per square foot for them. 
  • Roof repairs. Depending on their scale and complexity, any roof repairs add to the overall synthetic slate roofing cost. The regular minor repairs price ranges from $150 to $1.500, while for a major repair, a roofing contractor may charge between $1.500 and $7.000.
  • Roof ventilation. Proper ventilation is essential for the longevity of the roof. Yet, building or modifying ventilation systems may increase the end cost by $300 to $650. 
  • Soffits and fascia replacement. These structures may require either replacement or repair, which imposes additional expenses of $6 – $30 per linear foot.
  • Drip edge installation. The drip edge helps to protect the roof from water damage. Yet, the cost of materials and the work also affects the end project price by adding to it $1 – $3 per linear foot.
