The answer to 'how to maintain drip edge' is to regularly inspect and clean the drip edge on your roof. The drip edge is a metal flashing that runs along the edges of your roof, directing water away from your home's siding and foundation. Proper maintenance of the drip edge is important to prevent water damage and leaks.
To maintain your drip edge, start by visually inspecting it for any damage, such as cracks, holes, or loose connections. Use a soft-bristle brush to gently clean away any debris or buildup on the drip edge. If you find any issues, you may need to replace or repair the drip edge. For more significant damage or if you're unsure how to proceed, it's best to consult a professional roofing contractor.
