We recommend inspecting your roof at least twice a year, typically in spring and autumn. Additional inspections should be conducted after severe weather events such as storms, heavy snowfall, or high winds. Regular inspections help identify potential issues before they develop into costly problems.

The lifespan of a roof varies significantly depending on the material used. Clay or concrete tiles typically last 50-75 years, slate can last 75-100+ years, metal roofing 40-70 years, flat roofs 15-30 years (depending on material), and asphalt shingles 15-30 years. These estimates assume proper installation and regular maintenance.

To prevent moss growth: ensure good roof ventilation, keep gutters clean, trim overhanging tree branches to increase sunlight exposure, and install zinc or copper strips at the roof ridge which release moss-inhibiting metals when it rains. Regular professional cleaning can also help manage existing moss growth.

While overlaying a new roof on top of an existing one is sometimes possible, it's not always the best solution. It can hide underlying problems, add excessive weight to your roof structure, and may void some warranties. In most cases, we recommend complete removal of the old roof to ensure any structural or decking issues are addressed before the new roof is installed.
