Roof cleaning improves appearance and removes moss and lichen that hold moisture. Match the method to the roof, soft wash for fragile or painted tiles, pressure wash for sound metal and concrete. It is also the right time to check ridge caps.
💰 Ways to save
- Do gutters at the same time, the access is already set up.
- Soft washing is gentler on old tiles and avoids the damage aggressive pressure washing can cause.
- If the roof is being cleaned for sale, a wash is far cheaper than a full restoration and often enough.
