Before you commit to a $5,000+ roof restoration, get a clean quoted first. Many roofs that look like they need restoration just need a professional soft wash — at a fraction of the price.

The terms roof cleaning and roof restoration are sometimes used interchangeably in the industry but they refer to very different scopes of work at very different price points. Understanding the difference could save you thousands of dollars. A roof clean removes biological growth and surface grime — it restores the appearance of the roof surface. A roof restoration is a full remediation that typically includes cleaning, repointing ridge caps, recoating or painting tiles, and replacing damaged tiles — it addresses underlying structural issues beyond surface soiling. Most homeowners who think they need a restoration actually only need a professional clean. The transformation after a thorough soft wash on a heavily soiled roof can be remarkable — and the cost is a fraction of restoration.
A professional soft wash roof clean covers: removal of all biological growth (algae, lichen, moss); cleaning of all tile surfaces back to original colour; gutter clear and flush; solar panel cleaning (included in our Roof Clean package); and before and after photography. It addresses surface soiling and biological growth — not structural issues.
A roof restoration typically covers: full clean; repointing of ridge caps and hip tiles with fresh mortar; rebedding of loose ridge caps; replacement of cracked or broken tiles; application of roof sealer or membrane coating; and sometimes full repaint. It's a significant structural and cosmetic remediation — appropriate when the roof has genuine structural issues beyond surface soiling.
You probably only need a clean if: your tiles are intact (no cracks, no breakage); your ridge cap mortar is sound (no crumbling or loose caps); you don't have active leaks; and the roof looks dirty, stained or mouldy rather than structurally compromised. You may need restoration if: you have cracked or broken tiles; ridge cap mortar is crumbling or failing; you have active leaks; or the tile coating has genuinely deteriorated beyond surface soiling.
Get a clean done first and reassess. The results of a professional soft wash on a dirty roof are often dramatic enough that restoration becomes clearly unnecessary. If after the clean you still have structural concerns — cracked tiles, failed pointing — those can be addressed as separate, targeted repairs. This approach is almost always cheaper than committing to a full restoration upfront.
If your tiles are structurally sound (no cracks), the ridge cap mortar is intact and you don't have leaks — you almost certainly just need a clean. The 'aged' appearance of most roofs is biological growth, not genuine tile deterioration. Get a clean quoted and assessed before committing to restoration.
Roof restoration makes sense when there are genuine structural issues — cracked tiles, failed pointing, active leaks — that a clean won't fix. For most roofs, cleaning is the right first step. Restoration is expensive and unnecessary if the underlying structure is sound.
Absolutely — it's one of the most common misunderstandings in roofing. Heavy biological growth and grime dramatically change the appearance of a roof, making sound tiles look far more aged and compromised than they are. Professional soft wash cleans frequently reveal a roof in excellent condition underneath years of surface soiling.
Roof cleaning starts from $799 for a standard home. Roof restoration typically costs $3,000 to $8,000+. If your roof just needs a clean, you could save thousands by correctly identifying what the roof actually needs.
