The average commercial roofing system requires repair, restoration or replacement after 20 - 30 years. Depending on the type of roofing system and roof condition, a roof replacement can seem overwhelming and challenging, but GRLA’s building envelope team adds value by navigating the process from start to finish. Every roof is unique and the existing conditions can vary, hiring a designer is beneficial to interpret the building code and determine the most cost-effective replacement process.
