What to Do When Your Roof Is Leaking During Heavy Rain

A useful roofing decision starts with the cause and extent of the defect, not a generic product claim. Inspection, photographs and a written scope help distinguish a targeted repair from maintenance or full renewal. This guide explains the practical checks a Bromley property owner should make before requesting or approving work.

Quick answer

A useful roofing decision starts with the cause and extent of the defect, not a generic product claim. Inspection, photographs and a written scope help distinguish a targeted repair from maintenance or full renewal.

Safe first actions

• Keep people away from bulging ceilings, loose materials and wet electrical fittings
• Move possessions or contain drips only where it is safe
• Do not climb onto the roof or improvise access during bad weather
• Take photographs from a safe location and note when the leak started
• Call emergency services or the appropriate utility professional if there is immediate danger

Temporary versus permanent work

A first visit may only make the area safer or reduce water entry. Ask for the temporary measure and the later permanent repair to be described separately. Bromley Roofing’s published hours are 8am–6pm; availability and roof access depend on weather and safety.

Match the defect to the weather mechanism

Wind can displace loose units and drive rain beneath marginal laps. Prolonged rainfall tests outlets and valleys. Temperature change moves metal, membranes and junctions. The inspection should identify which mechanism fits the evidence instead of describing weather as a catch-all cause.

• Windward edges, ridges and perimeter trims
• Outlets and overflow routes after sustained rain
• Lead and membrane movement points
• Debris collecting behind parapets or in valleys
• New marks after a specific weather event

What should be inspected?

• Where and when water or damage first appeared
• Covering, flashings, junctions and drainage around the affected area
• Whether defects are isolated or repeated across several slopes
• Condition of underlay, deck or visible timbers where accessible
• Safe access, scaffolding and waste-removal needs
• Materials, exclusions and assumptions in the quotation

Plan around an occupied property

Roof work above homes and businesses needs a clear plan for noise, temporary weathering, entrances, gardens and internal protection. Agree who moves vulnerable belongings and how an unexpected opening will be made safe at the end of the day.

• Daily weathering responsibility clear
• Occupied rooms protected below
• Working hours and contact agreed
• Completion and waste checks recorded

Protect people and property below

Roof safety includes falling materials as well as falls from height. Agree exclusion areas, scaffold protection, secured materials and how entrances or neighbouring spaces will be managed while work is overhead. The HSE roof-work guidance explains the main requirements and hazards.

Questions to ask in the quotation

• What evidence supports the proposed repair?
• Is the work temporary or permanent?
• What is included and excluded from the price?
• What maintenance or future renewal should be budgeted?

Frequently asked questions

Will a roofing quote replace a building survey?

No. A roofing quotation addresses a proposed work scope. Structural advice, valuation, asbestos surveying and a full building survey are separate professional services.

Can a roofer diagnose this from photographs?

Photographs can help initial triage, but they rarely show concealed layers, the complete water path or substrate condition. A site inspection is normally needed before a firm permanent-repair scope.

How should guarantees be compared?

Compare the exact work covered, duration, exclusions, maintenance duties and who stands behind the guarantee. A guarantee cannot compensate for an unsuitable specification.
