Silicone roof coatings are popular because they provide a highly reflective surface that protects the roof from UV rays, extending the roof’s life. However, despite their UV resistance, silicone coatings can still experience some degradation over time, especially if the coating was applied unevenly or is exposed to harsh environmental conditions like extreme sunlight, temperature swings, or airborne pollutants. UV degradation usually appears as chalking, cracking, or a chalky residue on the surface, which means the coating is breaking down and losing its ability to protect the roof effectively. Simple DIY checks involve closely inspecting the coated surface for fine cracks, peeling spots, or discoloration, especially in areas exposed to the most sunlight. Running your hand over the roof surface to feel for powdery residues or brittleness can also indicate the start of deterioration. These physical signs are early warnings the coating might need refreshing or repair.
If you notice such signs, it’s wise to call a professional roofer experienced in silicone coatings. They can assess whether the coating can be cleaned and recoated or if more extensive repairs are necessary. When you talk to a contractor, it’s smart to ask: “How do you evaluate the current condition of the silicone coating and what are the best repair steps?” and “What type of warranty or guarantee do you offer after recoating or repairing the roof to ensure long-term protection?” These questions help clarify the roofer’s expertise and what protections you get. Keeping documentation and records of all roof work is important for code compliance and preserving your warranty. UV degradation is often gradual but catching it early and addressing it correctly will save you costly roof replacement later.
