CLEAN+ · Roof Cleaning Program
A Dirty Roof Costs You
More Than You Realise
Debris, organic growth, salt deposits, and blocked gutters are silently shortening the life of your roof, voiding your warranty, and creating leak risks — often without any visible sign until it's too late. CLEAN+ is Ideal Asset Maintenance's scheduled roof cleaning program for commercial and industrial buildings.

The CLEAN+ Program
Cleaning That Protects
Cleaning That Protects
the Roof, Not Just Looks After It
Roof cleaning on a commercial or industrial building is not the same as hosing down a surface. Done incorrectly — with the wrong pressure, the wrong method, or by someone who doesn't understand the roof system underneath — cleaning can dislodge flashings, crack sealants, force water into lap joints, and create the very leaks it was meant to prevent.
CLEAN+ is delivered by licensed roofing tradesmen who understand the construction of the roof they are cleaning. That means every method, pressure setting, and chemical treatment is selected with the roof's integrity in mind — preserving coatings, flashings, sealants, and penetration seals rather than compromising them.
CLEAN+ is available as a standalone service for a one-off or scheduled clean, or integrated into a PREVENT+ preventative maintenance program for customers who want cleaning and maintenance managed under a single program and a single point of contact.
Licensed Tradesmen — Not Cleaners
Every CLEAN+ visit is carried out by a licensed roof plumber. They understand the roof system, select the right method for the material, and flag any defects they identify during the clean — at no extra charge.
Warranty Compliance
Most roof manufacturers require cleaning at least every six months as a condition of the warranty. CLEAN+ is documented and can be used as evidence of compliance if a warranty claim arises.
Integrity-Preserving Methods
We select pressure, method, and chemical treatment based on the roof material and condition — never a one-size-fits-all approach that risks damaging coatings, sealants, or flashings in the process.
Flexible Delivery
Book CLEAN+ as a standalone one-off service, a scheduled standalone program, or fully integrated into a PREVENT+ preventative maintenance program — whichever suits your asset and your operational schedule.
Why It Matters More Than Most Owners Realise
Four Things Happening to Your Roof Right Now
A commercial or industrial roof that isn't regularly cleaned doesn't just look neglected — it deteriorates faster, leaks sooner, and costs significantly more to maintain over its life. These are the four forces working against it.
Most Underestimated Risk
Blocked Gutters Cause Water Backup and Leaks
Debris accumulation in gutters and drainage points is the single most common — and most underestimated — cause of leaks in commercial and industrial buildings. When gutters are blocked, water backs up and ponds on the roof surface. It then finds its way through lap joints, around penetrations, and behind flashings — areas that are watertight under normal drainage conditions but were never designed to hold standing water. The resulting leak appears to come from the roof, when the actual cause is drainage failure. Regular clearing of gutters and drainage points is the most cost-effective leak prevention measure available.
Organic Growth Physically Damages the Roof Surface
Lichen, moss, and algae are not just cosmetic problems — they actively damage the roof surface beneath them. Lichen in particular produces organic acids that etch into metal coatings and sealants, while the root structures of moss physically lift and separate roofing materials at laps and seams. Left untreated, organic growth accelerates the deterioration of the roof surface, shortens the life of the coating system, and creates entry points for water — particularly after heavy rain dislodges established growth and exposes the damaged surface underneath.
Salt and Pollutant Buildup Accelerates Corrosion
In coastal and industrial environments, salt deposits and airborne pollutants accumulate on metal roof and wall cladding surfaces over time. Salt is highly corrosive to metal roofing systems — particularly in areas where the protective coating has worn or been scratched — and accelerates the rusting and pitting of exposed metal. Regular cleaning removes salt deposits before they have time to cause structural damage, and is a specific requirement of most manufacturers' warranties for buildings within a certain distance of the coast or industrial zones.
Most Warranties Require Cleaning to Remain Valid
Roof manufacturer warranties are not unconditional — they carry maintenance obligations, and scheduled cleaning is almost universally among them. Failure to maintain a documented cleaning program can result in a warranty claim being denied, even where the failure that caused it was a genuine product defect rather than owner neglect. CLEAN+ visits are documented and can be produced as evidence of compliance if a warranty claim is required, giving you the protection the warranty was intended to provide.
What CLEAN+ Includes
Four Cleaning Methods — Applied to the Right Problem
Not every roof needs the same treatment. We assess the roof's material, condition, and contamination before selecting the appropriate method — never a blanket approach that risks causing damage.
Pressure Washing & Soft Washing
High-pressure washing removes heavy soiling, dirt, and surface contamination — but applied at the wrong pressure or angle it can force water under laps, dislodge sealants, and damage coatings. Our licensed tradesmen select the correct pressure and method for the specific roof material, age, and condition — including soft washing (low pressure with chemical treatment) where the surface requires a gentler approach.
- Pressure and method selected for the specific material
- Soft washing used where high pressure would risk damage
- Careful attention to flashings, laps, and penetrations
- Compliant with manufacturer cleaning requirements
Debris & Gutter Clearing
The single most important cleaning task for any commercial or industrial roof — yet the one most commonly skipped between major cleaning programs. All loose debris is removed from the roof surface, gutters, valley gutters, downpipes, and drainage points. We check that water is flowing freely through the full drainage system before leaving the site — not just visually clearing the gutter opening.
- Full roof surface debris removal
- Gutter and valley gutter clearing
- Downpipe and drainage point clearance
- Drainage flow confirmed before completion
- Identification of any damaged or blocked drainage components
Organic Growth Treatment
Lichen, moss, and algae require more than pressure washing to remove and prevent — the root systems of established growth remain after surface cleaning and regrow quickly without treatment. We apply a biocide treatment that kills the organic growth at the root and inhibits regrowth, combined with mechanical removal of established colonies. Treatment is selected to be compatible with the roof material and to avoid runoff risk to adjacent drainage systems.
- Biocide treatment killing growth at the root
- Mechanical removal of established lichen and moss colonies
- Inhibitor application to slow regrowth
- Treatment compatible with roof coating and drainage system
- Assessment of surface damage beneath growth
Salt Deposit Removal
Salt deposits on metal roofing systems require targeted treatment — pressure washing alone does not fully remove salt crystals that have formed within the coating surface, and using the wrong chemical treatment can accelerate corrosion rather than prevent it. We apply a neutralising wash formulated for metal roofing systems that removes salt deposits without stripping or damaging the protective coating, followed by a clean water rinse to remove all chemical residue.
- Neutralising wash formulated for metal roofing
- Full roof and wall cladding surface treatment
- Clean water rinse to remove all chemical residue
- Assessment of coating condition following treatment
- Particularly recommended for coastal and industrial locations
How CLEAN+ Is Delivered
Standalone Service or Integrated into PREVENT+
CLEAN+ works both ways — as a standalone cleaning service for customers who want a one-off or scheduled clean, or fully integrated into a PREVENT+ preventative maintenance program for customers who want everything managed together.
Option 01
CLEAN+ Standalone
Book CLEAN+ as a one-off service or on a scheduled basis independent of any maintenance program. Suitable for customers who already have a maintenance contractor in place but want a specialist roofing tradesman handling the cleaning, or for assets that require cleaning but not a full preventative maintenance program.
Standalone CLEAN+ visits include a brief condition observation — if our licensed tradesmen notice anything during the clean that warrants attention, we flag it in a short written note provided after the visit. This is not a full roof condition report, but it means defects aren't overlooked while we're on the roof.
Option 02
CLEAN+ Integrated with PREVENT+
For customers on a PREVENT+ preventative maintenance program, cleaning is scheduled as part of the program — coordinated with maintenance visits so the roof is cleaned and maintained under a single program, by the same team, with a single point of contact managing everything.
Integrating CLEAN+ into a PREVENT+ program means cleaning is never overlooked between maintenance visits, warranty requirements are continuously met, and a single comprehensive roof condition report covers both the cleaning and maintenance outcomes after every scheduled visit.
Why It Matters Who Cleans Your Roof
A Cleaning Contractor and a Licensed Roofer Are Not the Same Thing
Most commercial cleaning contractors have no specific knowledge of roofing systems — they clean to a specification, not to a standard. The difference matters when you are cleaning a roof worth hundreds of thousands of dollars with components that can be damaged by the wrong pressure, angle, or chemical.
Our licensed tradesmen approach every CLEAN+ visit the same way they approach a maintenance visit — understanding the roof system, working around its vulnerabilities, and flagging anything that needs attention. You get a clean roof and an informal condition observation in the same visit.
