Flat Roof Focus: Reviewing 2025 and preparing for 2026 Success

As the year draws to a close, your EPDM roof deserves a quick health check. Winter weather can expose weaknesses in flat roofs, and small issues left unchecked can quickly turn into costly repairs. This guide will walk you through a simple rubber roof maintenance routine to help you keep your EPDM roof safe, watertight, and ready for the colder months.

One of the most important steps in EPDM roof maintenance is clearing away leaves, moss, and twigs. Organic matter can trap moisture and block water runoff, leading to ponding water and potential leaks. Use a soft broom to gently sweep debris—never sharp tools that could damage the membrane. Keeping the surface clear ensures proper drainage and protects your roof throughout winter.

Blocked drains are one of the most common causes of flat roof leaks. Inspect your outlets, gutters, and down pipes to ensure water can flow freely. Remove any leaf or debris buildup to prevent ponding water. A well-maintained EPDM roof drainage system is essential for keeping your roof watertight during heavy winter rain.

There should never be standing water on your flat roof. If you notice ponding after rainfall, monitor it closely. Persistent ponding places stress on the EPDM membrane and substrates beneath, potentially shortening the lifespan of your roof. If the issue continues, consult a professional about improving drainage or insulation—key steps in flat roof winter preparation.
