How often should a roof actually be inspected?

Roof inspections should be carried out periodically and after significant weather events, particularly on older or complex roofs. Regular inspections can identify loose materials, fixing deterioration, blocked drainage and flashing issues before they develop into more serious problems.

Can maintenance prevent the need for a full re-roof?

Regular maintenance can help extend the useful life of a roof by identifying and addressing minor defects before they become widespread failures. However, maintenance cannot prevent replacement where the underlying roof system has reached the end of its serviceable life.

Will you remove all the moss and lichen from my roof?

Moss and debris are removed where they create a genuine performance, drainage or moisture-retention issue. The appropriate cleaning method depends on the roofing material and condition, with care taken to avoid unnecessary damage to existing slates, tiles or roof finishes.

Do you provide a written record after each visit?

Yes. Where a maintenance inspection is carried out, a written condition report can record the roof's condition, identified defects, maintenance work completed and any recommendations for future monitoring or repair.

Is pressure washing a good way to clean a roof?

Pressure washing is not suitable for every roof and can damage or dislodge certain roofing materials. The cleaning approach should be selected according to the roof covering, condition, age and the type of moss or debris present.

How is a maintenance programme priced?

Maintenance costs depend on roof size, accessibility, materials, condition, drainage requirements and the frequency of inspections. A roof assessment allows the appropriate maintenance requirements and programme to be established.

Understanding Roof Maintenance

Most roofing issues develop slowly in areas that are not visible without close inspection.

Common early-stage issues include:

Fixings loosening before visible material failure
Moss retaining moisture at overlaps and junctions
Reduced gutter capacity caused by gradual debris build-up
Flashings opening slightly due to thermal movement
Minor slipped slates or tiles exposing underlay
Blocked outlets creating slow water backflow

Individually, these are not emergencies — but together they become leaks and structural deterioration.

Regular roof inspections in Chiswick can identify early defects before they develop into leaks, structural deterioration or costly emergency repairs.

Weathering vs Roof Failure

Slate Roofing

Slate can remain durable for decades, but fixings, flashings and roof detailing still require periodic inspection.

Clay Tile Roofing

Tiles are more porous and can retain moisture when moss builds up, increasing long-term stress on the system.

Lead & Flashings

Lead moves with temperature changes, and repeated expansion can create fatigue at key stress points.

Flat Roofing Systems

Flat roofs rely on continuous integrity — even small punctures or failed upstands can become entry points.

Copper & Zinc Roofing

These materials self-protect through patina, but still require inspection at joints and seams.

What a Roof Maintenance Visit Includes

Roof Condition Assessment

Detailed inspection to identify current condition and emerging risks.

Moss & Debris Management

Careful roof cleaning and moss removal are carried out only where growth creates a genuine performance or drainage issue.

Gutter & Valley Clearance

Keeping drainage routes clear to prevent water-related damage.

Fixing & Flashing Checks

Inspection of slates, tiles, leadwork, and vulnerable junctions.

Ridge, Hip & Chimney Review

Checking key areas where weather damage often begins.

Written Maintenance Report

A documented record to monitor roof condition over time.

From Maintenance to Repair — Controlled Escalation

Why Architectural Roofing Requires a Different Standard

Preventative roof maintenance helps identify problems early, reducing the risk of unexpected failures and emergency repairs.

When issues are discovered:

Emergency Action Only When Required: Urgent repairs are recommended only where immediate protection is needed.
Early Warning Signs Identified: Minor defects are recorded before they develop into larger problems.
Repairs Clearly Defined: Any repair recommendations are separated from routine maintenance work.
Larger Issues Monitored: Significant defects are documented with clear next steps.

From Maintenance to Repair — Controlled Escalation

What Causes Most Roof
Problems Over Time

Water Retention

Moss and debris can trap moisture against roofing materials.

Fixing Failure

Ageing fixings can gradually lose their strength.

Blocked Drainage

Restricted water flow creates pressure on the roof system.

Flashing Movement

Small gaps can expand into larger leaks over time.

Slipped Materials

Loose slates or tiles can expose vulnerable areas.

Vegetation Build-Up

Plant growth increases moisture and maintenance demands.

Our Roof Maintenance Process

Baseline Roof Survey

We record roof condition, materials, drainage, and early wear.

Scheduled Inspections

Each visit is measured against previous records to track real changes over time.

Preventative Measures

We intervene only where function is at risk — not for cosmetic uniformity.

Drainage Clearance

Gutters, valleys, and outlets are cleared and tested for real flow performance.

Fixing & Detail Inspection

We check slates, tiles, ridges, flashings, and verges for movement or failure risk.

Condition Reporting

Each visit includes a written report for tracking, planning, and insurance use.

Common Roofing Questions

This depends on age, material, tree cover and roof complexity, but most period properties benefit from at least an annual visit, with biannual inspection worthwhile where significant tree overhang or a complex roof geometry is involved.

It can significantly extend a roof’s serviceable life by catching fixing failures, flashing cracks and drainage issues early, though it can’t indefinitely postpone replacement once a roof genuinely reaches end of life.

Not necessarily, and we’d advise against it in most cases. Established lichen is largely harmless and removing it can damage the underlying slate or tile. Moss, which retains moisture and can lift tiles, is treated differently and removed where it poses a genuine risk.

Yes, every maintenance visit generates a documented condition report, useful both for tracking the roof’s condition over time and for insurance or resale purposes.

Generally not, on the roofs we work on. Aggressive pressure washing can strip natural weathering, force water beneath overlaps, and damage older or more porous roofing materials. We use methods matched to the specific material rather than a single blanket approach.

Based on roof size, complexity, access, and visit frequency. We’ll typically propose a programme once we’ve seen the roof, rather than pricing blind against a standard package.
