Plan roof access for painting.

Because these areas are difficult to reach, "roof access" is often the most significant part of the project. Whether using traditional scaffolding, towers, or cherry pickers, ensuring safe and stable access is essential for a high-quality, long-lasting finish that survives the UK's wind and rain.

What Does the Work Involve?

• Site Survey: An initial inspection of the roofline, eaves, and gutters to identify rot, loose boards, or failing masonry.
• Access Setup: Installation of safe working platforms, ranging from ladders with stand-offs to full independent scaffolding or a Mobile Elevated Work Platform (MEWP).
• Surface Preparation: Deep cleaning to remove moss, lichen, and dirt, followed by scraping back flaking paint and sanding the timber to a smooth finish.
• Minor Repairs: Filling cracks with high-performance wood filler, securing loose boards, and treating any "soft" spots with wood hardener.
• Priming and Painting: Application of specialist exterior primers followed by two coats of weatherproof flexible paint (such as bedacryl or microporous finishes).
• Gutter Maintenance: Cleaning the exterior of gutters and downpipes, often painting them to match or contrast with the new roofline colour.
• Protection and Cleanup: Using heavy-duty dust sheets to protect conservatories, parked cars, and landscaping from paint splatters.

Typical Costs

Costs for roofline painting vary significantly based on the height of your property and the type of access required. Prices below include VAT and represent 2025/26 UK averages.

The total cost is primarily driven by "up-time." If a painter can reach the entire roofline from a single scaffold tower, the price remains low. If your home requires a full "wrap-around" scaffold to reach gable ends and chimneys, access costs can easily exceed the cost of the paint and labour combined.

How Long Does It Take?

• Small Terraced Frontage: 1 day (including setup and two coats).
• Semi-Detached (Three Sides): 2–3 days, depending on the condition of the timber.
• Large Detached House: 4–7 days, allowing for scaffold strikes and movements.
• Weather Factor: Exterior painting in the UK is highly weather-dependent; expect delays if rain or high winds are forecast.

DIY or Professional?

While painting a skirting board is a standard DIY task, painting at roof height is a different matter entirely. Working at height is the leading cause of workplace fatalities in the UK, and the risks for an untrained homeowner are substantial.

Professional decorators have the insurance, equipment, and "head for heights" necessary to work safely. Furthermore, a professional finish at the roofline involves rigorous preparation that is physically demanding when balanced on a ladder. Unless you are working on a single-storey bungalow with level ground, hiring a professional is the safer and more durable choice.

Choosing the Right Tradesperson

• Check Insurance: Ensure they have Public Liability insurance that specifically covers "working at height" (some standard policies exclude this).
• Access Strategy: Ask exactly how they plan to reach the eaves. Avoid any contractor who suggests "balancing" on a standard ladder for long periods without proper tie-offs or staging.
• Portfolio: Look for photos of previous exterior work, specifically focusing on the neatness of the "cut-in" lines against the roof tiles.
• Questions to Ask:
  • Are you comfortable working around solar panels or satellite dishes?
  • Do you include the cost of scaffolding in your quote, or do I pay the scaffold firm directly?
  • What brand of paint do you use for high-exposure areas?
  • How do you handle rotten timber discovered once you are up there?

UK Regulations

All professional painting work at height must comply with the Work at Height Regulations 2005. This requires tradespeople to avoid risk where possible and use the most appropriate equipment to prevent falls.

• Scaffolding: Must be erected by a CISRS-qualified scaffolder and provided with a "handover certificate."
• Pavement Licences: If scaffolding needs to be placed on a public footpath, your contractor or scaffolder must obtain a permit from the local council.
• CDM 2015: Homeowners are responsible for ensuring their project is managed safely, which usually means hiring competent professionals.

Common Problems

• Hidden Rot: Timber often looks fine from the ground but is "punky" or soft once inspected closely. Painting over rot is a waste of money as the paint will peel within months.
• Over-Painting Gutters: Painting plastic gutters without the correct primer often results in unsightly flaking.
• Inadequate Preparation: Skipping the sanding stage means the new paint won't "key" to the old surface, leading to premature failure in the sun.
• Weather Traps: Painting too late in the autumn can result in "blooming" or moisture being trapped under the paint film, causing blisters.

Pro Tip: If you are having your roofline painted, it is the perfect time to have your gutters professionally cleared and checked for leaks, as the access is already in place.
