RAPTOR ROOFING & CONSTRUCTION LTD
Moss, dark streaks or blocked gutters are signs moisture is accelerating wear to tiles, flashings and gutters; we remove growths and debris using methods matched to the roof covering, check gutters and visible flashings, and highlight any items that need further repair. Tell us what you’ve seen and send a few photos so we can advise the right next step.
AN INTRODUCTION / 03
When moss, algae or leaves build up, acting now reduces the chance of leaks and more expensive repairs; we focus on material-appropriate cleaning, basic on-roof maintenance and clear advice about follow-up work you might need.
Seeing moss or blocked gutters makes the immediate priority stopping moisture being held against the covering and restoring proper drainage; we inspect visible roof elements, remove biological growth using non-invasive methods where appropriate, clear gutters and downpipes, and report any slipped tiles or damaged flashings. Provide roof photos, your postcode and any access notes when you enquire so we can suggest whether a remote assessment is sensible or a site visit is required.
EXPLORE THE OPTIONSOUR SERVICES / 03
Straightforward upkeep concentrates on four core tasks: cleaning roof surfaces of moss and algae, specialist moss removal where growth is established, preventative maintenance including gutter and tile checks, and formal roof inspections to assess condition; each service is planned around the roof covering and access constraints so cleaning does not create avoidable damage.
Staining or light biological growth on tiles and slates is treated with gentle cleaning methods matched to the covering to lift dirt and algae without dislodging tiles; our approach favours soft washing, manual brushing and careful rinsing and we always check gutters and flashings at the same visit, advising on any repairs beyond cleaning alone.
ENQUIRE ABOUT THIS SERVICEWhere thick moss has built up and is forcing tiles to lift or retain moisture, we remove the growth with careful hand tools and brushing techniques suited to the tile or slate, handling mechanical removal sensitively where necessary and combining it with targeted biocide application and guidance on follow-up treatments.
ENQUIRE ABOUT THIS SERVICETo prevent leaks we inspect gutters, downpipes, flashings and visible tiles, re-fixing slipped tiles and clearing debris from valleys and eaves as needed, and we flag obvious fascia or soffit rot so required carpentry or guttering work can be planned before small defects become water entry points.
ENQUIRE ABOUT THIS SERVICEUnsure about condition? We carry out a structured inspection that documents tile condition, flashings, drainage and any visible signs of wear, separating what cleaning will resolve from what needs repair and supplying clear photographs and written recommendations so you can decide next steps with realistic scope and cost outlines.
ENQUIRE ABOUT THIS SERVICEOUR PROCESS / FOUR STAGES
Proceeding follows a focused sequence: gather information and photos, assess access and material suitability, carry out the agreed cleaning or maintenance using the least invasive technique, and finish with a handover that lists any further repair work needed and next-step advice.
Begin by sending wide and close roof photos, your postcode and any access constraints; we use that information to decide whether a remote estimate is appropriate or if a site visit and a safe access plan are required, and to identify the roof covering so the correct cleaning method can be chosen.
On agreed cleaning visits we match the method to the material: soft washing, manual brushing and controlled rinsing for fragile coverings, and more robust hand removal where moss is very thick, avoiding high-pressure jetting on susceptible tiles and protecting plants and water outlets when biocides are used.
After cleaning we clear gutters and downpipes first to restore drainage, then attend minor repairs such as re-fixing slipped tiles, renewing short gutter sections or re-pointing small ridge mortar areas where safe to do so; larger items are presented in a clear proposal so you can approve further work with a full understanding of scope and cost.
At completion we carry out a walkaround and provide a photographic record of the work done, highlight any outstanding issues and set out practical steps you can take between visits to reduce debris and moss build-up, or arrange follow-up trades if brickwork, fascias or carpentry need finishing.
WHY CHOOSE RAPTOR / WHAT MATTERS
For effective roof care without causing damage, match methods and access to the roof covering, restore proper drainage and identify issues early so repairs are not left until leaks appear; our approach focuses on what can be achieved safely on your roof and what will need separate repair work.
Using the wrong technique risks damaging fragile tiles or bedding mortar, so we pick cleaning methods that preserve the covering—soft washing or hand brushing for delicate slates, cautious mechanical removal where moss is thick—allowing the roof to be cleaned without creating avoidable defects that lead to leaks.
Blocked gutters or slipping tiles increase the chance of water reaching timbers and internal walls; regular maintenance identifies loose tiles, failing flashings and blocked drainage early so you can fix them before interior damp or more extensive structural work becomes necessary.
Left on the roof, moss and debris trap moisture against tiles and underlay and accelerate deterioration; effective cleaning and routine checks restore drainage paths and remove moisture traps, reducing the likelihood of premature cover replacement caused by neglect.
INSIGHT / Roof Care Insights
Deciding between cleaning and maintenance depends on the roof covering, access and the types of growth or defects present; clear photos and basic roof details let us advise whether cleaning alone will suffice or whether inspection and repair should follow.
Moss, algae and lichen trap moisture against tiles and can lift bedding mortar or ridge tiles, creating gaps where water can enter; cleaning removes the growth that holds moisture and reveals the underlying condition so sensible repair decisions can be made. Gentle brushing and controlled detergent application are usually safer than pressure washing on slates and older clay tiles, which are prone to breakage under mechanical force, while some concrete tiles tolerate firmer mechanical removal but still need precautions to avoid surface erosion. Runoff must be managed to protect plants and drains, and a cleaning visit often begins by clearing gutters and downpipes to restore drainage before removing organic growth from the main slope and inspecting flashings, ridges and valleys for vulnerable spots. For inaccessible or steep roofs the balance may favour more frequent inspections rather than aggressive cleaning attempts that increase safety risk; include a wide photo and a close shot when enquiring and note any recent internal leaks to help judge whether cleaning is likely to be adequate or whether additional repair work will be needed.
Preventing leaks requires work on gutters, downpipes, eaves, flashings and visible tiles; clearing gutters and ensuring downpipes run freely reduces load at eaves and the risk of water tracking behind fascia boards. During maintenance visits we examine valleys, chimneys and hip ridges where water concentrates, and re-seat loose tiles where safe to do so, while timber fascias and soffits are checked for obvious rot or detachments that would warrant carpentry repairs. Some maintenance actions are minor and can be completed during the same visit; other items need separate quotes so you can decide on further work. Keep ground-level access clear and remove parked cars where possible so ladders or edge protection can be set up safely, and a regular programme of inspection and light maintenance helps the roof perform while you budget for larger renewals if they become necessary.
Preparing to book roof care means considering access, roof covering and surrounding trees; steep or multi-storey roofs may require scaffolding, which affects cost and the scope of practical work, while fragile coverings will limit mechanical methods and may demand hand removal only. Nearby trees increase leaf and moss loads and complicate safe working over gardens and conservatories, so take photos showing plants close to gutters and note any restricted street access or parking limitations so safe access planning is included in the initial assessment. Provide approximate roof age, details of recent repairs and where leaks have been noticed inside; that information helps prioritise what to do on site. Above all, avoid climbing or working on the roof yourself—professional assessment prevents accidental damage and safety risks and clarifies whether cleaning will be effective or if repairs must come first.

QUESTIONS / ROOF CLEANING & MAINTENANCE
Questions about safety, scope or related repairs are answered below to help you prepare before contacting us and make the initial assessment as efficient as possible.
ASK ANOTHER QUESTIONShaded roofs or properties close to trees benefit from more frequent checks; many owners use inspections to set a sensible interval tailored to their covering type, shading and how quickly moss returns, and an inspection helps establish the right frequency for your home.
Choosing the correct method for your covering—soft washing, careful brushing or hand removal—prevents damage to tiles; high-pressure jetting can harm many materials, so we avoid it unless the covering is confirmed to tolerate stronger methods and it’s safe to proceed.
Small clearances and minor repairs are often practical to complete during the same visit; larger renewals of fascias, soffits or long gutter runs are quoted separately so you can review costs and priorities before committing to replacement work.
Send a wide roof photo, two close shots of problem areas, your postcode and any access constraints (narrow street, no off-street parking, overhanging trees) and we’ll advise whether a remote estimate is sensible or if a site visit is needed to plan safe access and the correct cleaning method.
When chemical treatments are recommended, we apply them selectively and in a way that limits runoff to plants and drains; we explain why a biocide is suggested and how nearby vegetation and watercourses are protected so you can decide whether to include that step.
Should cleaning or inspection reveal slipped tiles, damaged flashings or rot, we separate those items into a written recommendation with costed options so you can choose whether to proceed; cleaning can be completed first to reveal the full extent of faults, or repairs can be scheduled once you approve the proposal.
