Generally roofs are meant to last for decades. However, in some cases, roofs require resealing when they are more than a decade old. Initially, the cracks open at a smaller scale but once the microorganisms begin to settle in the cracks, they begin to open up. That is when a reseal is needed. It blocks the passage for the microorganisms and hence fills the gap. As a professional roof sealer, we only use the best roof sealant in the market. Depending on the damage, we can apply a roof sealant paint or a roof sealant spray. Do not let a small crack turn into a bigger problem, call a professional to apply a new roof seal to your roof and turn it good as new!
