Professional Cleaning Services

Keeping your roofline clean isn’t just about looks—it’s about protecting your home. In Port Talbot and the surrounding areas, our climate encourages moss, algae, and lichen to take hold on roofs, while leaves and debris clog gutters and downpipes. Left unchecked, this can lead to damp issues, leaks, staining, and costly repairs.

At D. Sullivan & Sons, we’re a family-run team with over 20 years’ experience in exterior cleaning across South Wales. We clean house roofs, gutters, downpipes, fascias and soffits, and conservatory roofs using safe, proven methods, including the industry-leading SkyVac system for high-reach gutter clearing.

What we clean

We provide a comprehensive roofline and conservatory care service for homes in Port Talbot, Baglan, Cwmafan, Margam, Sandfields, Taibach, and nearby villages.

We clean:

• House roofs (moss removal, targeted treatments)
• Gutters (full debris removal and flow checks)
• Downpipes (blockage clearance and testing)
• Fascias and soffits (wash-down and brightening)
• Conservatory roofs (uPVC frames and polycarbonate or glass panels)

If you’re seeing overflow during rain, green streaks on fascias, or moss shedding from the roof, it’s time to act.

Why regular roofline cleaning matters

• Prevent leaks and damp: Blocked gutters force rainwater to overflow against walls and into eaves, leading to damp patches, blown render, or timber rot.
• Protect your roof covering: Heavy moss retains moisture and can lift or degrade tiles over time; removing it helps the roof dry properly.
• Maintain kerb appeal: Clean gutters, bright fascias, and a tidy roof dramatically improve the look of your home.
• Reduce pests and odours: Decomposing leaf matter and standing water attract pests and cause smells; cleaning removes the source.
• Save money: Preventative maintenance is far cheaper than repairing water damage or replacing rotten timbers.

Our approach: safe, thorough, and tailored

Every home is different, so we match our method to your materials and condition. Typical workflow:

1. Inspection and risk assessment
   • Visual check of roof, gutters, and access routes
   • Identify fragile areas, slipped tiles, heavy moss, or prior damage
   • Plan safe working methods and cordon areas below
2. Gutter clearing with SkyVac
   • High-reach vacuum system with carbon fibre poles
   • No need for ladders on most homes
   • On-pole camera lets us monitor and verify removal of debris
   • Downpipes checked and cleared; we water-test where appropriate
3. Fascia and soffit wash-down
   • Low-pressure rinse with appropriate detergent
   • Soft brushes or cloths to brighten uPVC without scratching
   • Careful detailing around joints and corners
4. Roof cleaning (moss removal and treatment)
   • Manual moss removal using roof-safe tools (no aggressive blasting)
   • Light rinse where suitable; we avoid driving water under tiles
   • Application of a biocidal or softwash treatment to inhibit regrowth
5. Conservatory roof cleaning
   • Gentle, non-abrasive process for polycarbonate and seals
   • Specialist cleaners for algae and staining
   • Frame cleaning and final rinse for a streak-free finish
6. Final checks and tidy
   • Gutters re-checked, areas rinsed down, debris removed
   • Optional before/after photos on request
   • Maintenance advice tailored to your property

Why SkyVac makes a difference

Traditional gutter clearing with ladders can miss hidden blockages and risks damage to landscaping or the gutter itself. Our SkyVac system:

• Reaches high gutters safely from the ground
• Uses on-board cameras to see inside and confirm it’s clear
• Removes wet sludge, leaves, twigs, and plant growth efficiently
• Reduces disruption and speeds up the job

This approach is ideal for properties with conservatories or extensions that make ladder access awkward.

Common issues we solve in Port Talbot

• Moss shedding from roof tiles, collecting in gutters and blocking downpipes
• Overflow during heavy rain, streaking on walls, and damp ingress
• Green algae films on uPVC fascias, soffits, and conservatory roofs
• Black lichen spotting on frames and glazing bars
• Stagnant water in gutters attracting insects and causing odours

If you’ve noticed any of the above—especially after periods of wind and rain—your roofline likely needs attention.

Materials we work with

We tailor pressure, tools, and treatments to protect your property:

• Roof tiles: concrete, clay, and slate
• uPVC fascias and soffits
• Aluminium or steel gutters
• Cast iron heritage gutters (with care)
• Conservatory roofing: polycarbonate or glass
• Sealants and gaskets (kept intact with gentle methods)

We don’t use harsh abrasive pads or high-pressure blasting on sensitive areas. The aim is a deep clean with maximal protection.

How often should you clean roof, gutters, and conservatory roofs?

• Gutters and downpipes: every 6–12 months depending on trees, roof moss, and wind exposure
• Fascia/soffits: annually or as needed for kerb appeal
• Roof moss removal: every few years, with biocidal treatments to slow regrowth
• Conservatory roof: annually for clarity and to prevent algae build-up
