Your Roof Restoration
Everything you need to know before, during, and after the job
Read This First
Roof restoration is construction work - temporary mess for long-term protection. Here's what the experience typically looks like:
- A straightforward two-day process
- Some noise, water, and mess that clears up quickly
- A professional crew who've done this hundreds of times
- A restored roof that looks great and lasts for years
You won't need all of this
This guide is intentionally thorough because every home and every roof is different. Most customers only notice a handful of the things mentioned below - the rest are here so nothing ever comes as a surprise.
Before We Arrive
These steps help the job run smoothly and protect your belongings:
- Move cars away from the house (both days)
- Clear outdoor furniture, BBQs, and pot plants from around the house
- Cover or move anything under eaves - dirty water will drip during cleaning
- Secure pets inside and keep children away from work areas
- Make sure we can reach an outdoor water tap (cleaning day) and power point (painting day)
- Clear pathways so ladders and equipment can move around the house
- Clear gutters of any existing debris so roof wash-off can drain freely - details in During the Work
- Notify your neighbours at least 48 hours beforehand - details in Site Rules
Items left in work areas
Anything left under eaves, near walls, or within the splash zone will get wet and dirty. Clearing these areas before we start protects your belongings and helps the crew work efficiently.
The Two-Day Process
Day 1 - Cleaning & Repairs
The loudest and messiest stage. We high-pressure clean the entire roof (up to 4000 PSI), strip away years of moss, mould, and dirt, then inspect and repair - replacing damaged tiles, repointing ridge caps, and sealing flashings.
Day 2 - Coating
Quieter. We apply primer/sealer, then two coats of protective membrane. Flashings, vents, and exposed areas are coated for complete coverage.
Day 2 doesn't always follow immediately - weather and scheduling sometimes create a gap between stages. We'll keep you informed. For larger or more complex roofs, the job may take three days - typically two for cleaning and repairs, and one for coating.
During the Work - What You'll Notice
Everything below is a normal, temporary part of roof restoration.
Mess & Debris
High-pressure cleaning strips years of buildup off your roof. Dirty water, moss, and grit will run off onto paths, driveways, and garden beds. You'll see staining on eaves and rendered surfaces. We do our best to clean up on the day, but we can't guarantee everything will be spotless - a hose-down or the next rain will take care of any remaining residue.
Previously painted roofs: If your roof has been painted before, the cleaning process can strip loose or flaking paint, leaving paint chips and debris around the house. We can't guarantee we'll collect every piece. That said, most pre-painted roofs handle cleaning well and are usually less messy than roofs that have never been cleaned.
Red or orange tile roofs (never cleaned): If your roof has never been cleaned and has red or orange tiles, expect very noticeable coloured run-off. The natural tile colouring washes off in the water and will stain paths, driveways, and walls. This looks alarming but it wipes off easily with a wet cloth and cleans up with a hose or rain.
Water & Moisture
Small amounts of water get forced under tiles during cleaning - this is a known characteristic of tiled roofs, not a leak or error. Moisture will appear around light fittings, lights will flicker or briefly trip (they come back on once dry), and damp patches on ceilings will dry naturally within a few days.
If a light trips
Don't touch it. Let the moisture dry naturally - power returns once evaporation completes. If it hasn't come back after everything has dried out, it may indicate a pre-existing wiring issue where moisture has reached a connection that's shorting the circuit. In that case you'll need an electrician to investigate. Unfortunately this is an unavoidable possibility with any roof cleaning - water gets under tiles no matter how carefully the work is done, and we can't be responsible for underlying electrical faults.
Noise
Pressure washers, hammering, scraping, and crew movement on the roof. Day 1 is loudest, Day 2 is quieter. If you work from home or have noise-sensitive family members, plan around the scheduled days.
Dust from Vents
Vibration shakes loose dust sitting on ceiling insulation. You'll notice fine dust from bathroom and kitchen exhaust vents - a quick vacuum afterwards sorts it.
Gutters & Downpipes
What comes off the roof during cleaning is mostly fine sand, loose tile colouring, and surface grit - it's fine enough to flow cleanly through gutters and downpipes into the soakwell. If your gutters are already clear, this generally passes straight through without issue. However, if there's existing leaf litter, dirt, or debris already sitting in your gutters, the wash-off will build up on top of it and have nowhere to go. Any blockage is almost always caused by pre-existing debris, not by what comes off the roof. We'd recommend making sure your gutters are flowing freely before the job starts - it avoids problems and means the wash-off drains away as it should. Gutter and downpipe clearing is not included in the restoration.
Overspray & Vapour
You'll see a visible cloud around the roof when we apply the water-based sealer. This is water vapour from rapid evaporation - not paint mist. It doesn't settle on surfaces or coat anything. A small amount of fine overspray mist is possible when spray-painting outdoors - at distance, droplets dry mid-air and wipe off with a damp cloth. This is why notifying neighbours in advance helps.
You don't need to be home
As long as we have roof access from the front. If you'd prefer we don't have access to the backyard, just let us know - but please be aware that we won't be able to clean up any mess or debris that falls in areas we can't reach.
Appearance & Results
Roof coating seals and protects your roof while improving how it looks. Restoration improves an existing roof - it doesn't replicate the uniform finish of a brand-new one.
Normal Coating Characteristics
Patchiness While Drying
Different areas cure at different rates, so the coating looks uneven while drying. This settles as curing completes over the following days.
Minor Bubbling in Heat
Small bubbles appear where coating is slightly thicker and heat causes trapped moisture to expand. We pop, dry, and touch these up as part of quality control.
Paint Smell
We use Dulux Acratex, a water-based acrylic - it has a slight smell during application but nothing like oil-based paints. It fades quickly, usually within a few hours. Keep windows closed on painting day if you're sensitive to it.
Metal Roofs - Important Information
Metal roof finish
A spray-applied coating on a metal roof will not replicate a factory Colorbond finish. Because metal is flat and non-porous, coating sits entirely on top - so gloss levels, light angle, and paint thickness all affect how the surface looks. What often appears as "patchiness" is actually the light reflecting differently off varying gloss levels across the surface, not inconsistency in the paintwork itself.
Expect:
- Visible variation at spray overlap points - this is inherent to airless spray application regardless of operator experience or technique
- Sheen and gloss variation across the surface depending on light angle
- Existing surface imperfections (dents, ripples, rust pitting) visible through new coating
These are characteristics of the application method, not defects. They tend to become less noticeable over the initial months as the coating weathers naturally.
Something Look Off?
Coating often looks patchy, uneven, or inconsistent partway through before it looks right at completion. This is normal mid-process.
Just ask
Contact the office rather than assuming there's a problem - we'd rather explain what's happening early than have you worry.
We can't inspect every surface while the second coat is still drying. If anything needs attention after we leave, we come back and sort it out. Just let us know in writing (email or message) so we can arrange it - we ask that you give us the chance to inspect and fix anything before contacting anyone else.
Communication & Questions
For anything about materials, pricing, scope, or concerns - contact the office rather than the crew on site. The office team has your details and can give accurate answers. The crew focuses on the physical work.
Why we prefer written communication
- Creates a record - what was discussed, agreed, and promised
- Better answers - complex questions get researched and answered accurately
- Reaches us reliably - our team is often on jobs, and email gets through when calls can't
If we promise something in writing, you have proof. Email protects your interests as much as ours.
When calling makes sense: safety issues during work, same-day scheduling changes, or quick clarifications that need an immediate answer. Whether you email or call, we'll get back to you promptly.
Site Rules & Safety
Neighbour Notification
This is your responsibility - we can't notify your neighbours for you, and we'll assume you've taken care of it before we arrive. Please let them know at least 48 hours before work begins. The cleaning stage is the main concern - whilst we're careful, dirty water and debris may go over the fence, and neighbours should move vehicles and cover anything near the boundary as a precaution. You can't expect us to be able to warn them on the day - they may have already left for work, be away on holiday, or simply not be home. Overspray from the paintwork is very unlikely, but it's best to have the area clear to avoid any problems. Let them know the dates, that Day 1 (cleaning) is the loudest and messiest, and that the work is temporary.
Work Hours
Our crew generally works between 7 AM and 7 PM, Monday to Friday. Noisy work (cleaning, hammering) is kept to standard hours, but quieter tasks like coating may continue later while conditions are right.
No Other Trades During Work
The roof and work area need to be clear of other tradespeople on our scheduled days.
A common example
Even if solar installers say they'll be done by 7:30am - they won't be, and they'll be in the way. Please ensure no other trades are booked on the same days as our work.
Safety
- Keep children, pets, and visitors away from work areas
- Don't climb ladders or go onto the roof during work
- Don't stand directly below areas where debris will fall
Working Together
If you have questions about the job, please direct them to the office rather than the crew on site. Our crews work at heights with specialised equipment and need steady concentration - interruptions create a safety risk and slow things down. The office has your full job details and can give you accurate answers. We also ask that the crew aren't filmed or recorded beyond personal photos of the work itself.
A note on respect
Our crew are skilled tradespeople doing physical work in tough conditions - they take pride in what they do. We ask that they're treated with the same courtesy you'd expect in return.
Harassment, abusive language, intimidation, or repeated interference with the crew is not acceptable and constitutes a breach of the work agreement. If behaviour on site prevents the crew from working safely or professionally, we reserve the right to terminate the job - in which case cancellation fees and charges for work already completed will apply as outlined in your work agreement.
This has never been an issue for us, and we don't expect it to be. We just want everyone on the same page.
Weather, Timing & Scheduling
Weather
Roof restoration is weather-dependent, but a brief sprinkle of rain won't cause any issues - all the products we use are water-based. It would need to pour for an extended period to cause problems, and in the unlikely event that happens mid-job, we can adapt - whether that means coming back another day or touching up any affected areas. We do this work all year round and are well adapted to working around Perth's weather. That said, if conditions genuinely affect coating performance or crew safety, we'll pause or reschedule and keep you informed.
Hidden Issues
Dirt, moss, and old coatings hide underlying problems. Once we clean, we sometimes find cracked tiles, rust, or damaged flashings that weren't visible before. Your quote includes an allowance for common repairs - if we find anything beyond what's covered, we'll explain what's needed and get your approval before proceeding.
Scheduling Changes
When we book your job, we lock in crew, equipment, and a day that could have gone to another client. If something comes up, let us know as early as possible - we're flexible when we have time to adjust.
Late changes
Changes with less than 24 hours' notice mean our crew is already committed and another client has missed their slot. This can mean extra cost to cover the lost allocation - letting us know early is the easiest way to avoid it.
Similarly, if we arrive and can't proceed - other trades on the roof, locked gates, missing utilities - we'll need to reschedule, which pushes things back. Avoidable site issues can mean extra time on site, which may add cost. A quick check the day before goes a long way.
Paint Application - How Weather Affects Drying
We use Dulux Acratex Roof Membrane, a professional-grade coating system designed specifically for Australian conditions. Understanding how weather affects application helps you understand why timing and conditions matter.
Manufacturer Re-Coat Times
Minimum: 2 hours between coats (at 25°C, 50% humidity)
Maximum: Indefinite (can wait days or weeks without issue)
These times are based on ideal conditions. Real-world conditions vary significantly.
Hot Weather (Summer)
Why we work efficiently: Dulux specifies that coating should not be applied if roof surface temperature exceeds 40°C. In Perth summer, metal roofs and north-facing tiles reach this limit quickly - sometimes by 10am.
Faster application in heat isn't rushing - it's working within manufacturer limits. Applying coats efficiently after proper drying prevents adhesion problems from excessive heat. In extreme conditions, we pause work entirely.
Cool Weather (Winter)
Why we work slower: In cool or humid weather, moisture evaporates much more slowly. We monitor conditions carefully and wait as long as needed before applying the next coat. Rushing coats in cool or damp conditions risks poor adhesion, blistering, and long-term durability issues. We will take an extra day to deliver a coating that lasts 15 years rather than rush it and have problems within months.
Temperature & Drying - Why Heat Changes Everything
Temperature dramatically affects how quickly coatings dry and cure. This is standard coatings science and manufacturer guidance - not a shortcut or preference.
In the coatings industry, there's a widely accepted principle:
For water-based acrylic coatings, drying and curing reactions approximately double in speed for every 10°C increase above 25°C.
This principle (based on Arrhenius and Q10 temperature coefficient principles) is fundamental to coatings chemistry and referenced in manufacturer technical guidance.
What this means in real terms:
- At 25°C (ideal conditions): Manufacturer specifies approximately 2 hours between coats
- At 35°C (hot summer day): Drying reactions double - paint is ready in approximately 1 hour
- At 45°C+ (extreme heat): Surface is too hot to apply coating safely - we pause
In cooler weather, drying takes longer. We monitor conditions and wait as long as needed before applying the next coat.
Why you see us work differently in different weather
- Summer: We work efficiently once minimum drying is met because we have tight time windows before surfaces exceed 40°C
- Cooler weather: We take longer between coats and monitor conditions carefully before proceeding
- Same product, same crew, same techniques - but temperature influences the timeline
Temperature, humidity, airflow, and film thickness all interact to determine actual drying speed. This is why we can't always give you an exact "coating will be done by X time" - we're working with chemistry, not just a clock.
After the Job
Payment
The remaining balance is due on completion. If you're not home when the crew finishes, we'll let you know and payment is due within 24 hours. Bank transfer details are in your work agreement.
Check It Over
Have a look at the finished result within the first week and let us know in writing (email or message) if anything needs attention. We want to get it right - and the sooner we know, the sooner we can sort it.
Clean-Up
We tidy what we can on cleaning day, but some residue, grit, and staining will remain - particularly around eaves, paths, and driveways. A hose-down or the next decent rain will sort out anything left behind.
Gutters
Some debris from the cleaning - tile chips, grit, moss - will inevitably end up in your gutters. That's a normal part of stripping years of buildup off a roof and there's no practical way to prevent it. As outlined earlier in this guide, gutter and downpipe clearing is not included in the roof restoration and we're not responsible for anything left in or around the gutters after the work. It's a routine home maintenance task that needs doing periodically regardless, and after a roof restoration is a great time to get it ticked off. We'd recommend arranging a gutter clean shortly after the job is complete so everything is flowing freely.
Drying & Curing
The coating is touch-dry within hours and rain-resistant within about 2 hours, but it continues to harden over 7-14 days. During that time:
- Avoid walking on the roof
- Don't pressure-wash or scrub the coating
- Let it cure undisturbed for best long-term performance
Any dampness inside the roof cavity from cleaning dries naturally within a few days.
Looking After Your Roof
- Inspect twice a year - after summer and after winter
- Keep gutters clear of leaves and debris
- Check flashings around chimneys, vents, and valleys
- Watch for moss or algae regrowth and clean if needed
- Fix minor issues early before they grow
- Trim overhanging branches to reduce leaf buildup
You're Well Prepared
This guide covers a lot of ground, but the process itself is straightforward. A bit of preparation, clear communication, and realistic expectations go a long way.
If anything's unclear or you'd like to talk through any part of this before we start, get in touch any time. We're happy to help.
Our goal is a smooth job, a great result, and no surprises - this guide exists to make that happen.
