Should You DIY or Hire a flat roof professional?

Why flat roof repairs are necessary

Repairs are necessary for flat roofs to ensure that the structure remains watertight and prevents further damage. Water infiltration can lead to leaks, which can cause damage to the interior of the building, including the walls, ceiling, and electrical and HVAC systems. In addition, standing water on a flat roof can lead to mold and mildew, which can have negative health effects and weaken the roof's structural integrity.

By performing regular maintenance and timely repairs, you can extend the lifespan of your flat roof and protect your investment in your commercial building but that is something we cover in our article How to Maintain a Flat Roof.
