Roof and drainage checks from ground level | Homecode

What is known — and what is not

Non-invasive observations

• Observe and photograph the pitched-roof planes and roofline only from firm lawful ground within the property boundary and outside traffic or falling-object zones. [1][2]
• Use optical zoom only while stationary on that verified ground position; if the view is insufficient, record the area as unknown. [3][2]
• Observe gutters, downpipe heads and visible joints from the same ground position; record only visible overflow marks, staining, sagging, vegetation or detached parts. [4][2]
• End this route if closer access, a ladder, leaning from an opening, contact, cover removal, testing, repair, loose material, a suspect material, an active leak or another hazard is involved. [1][2]
• Ground-level images are screening evidence only and do not establish watertightness, structural condition, material identity, drainage capacity or remaining life. [3][4]

Evidence to request

• The age and specification of roof coverings, membranes, flat-roof systems and rainwater goods
• Roofing, chimney, gutter and drainage inspection reports, invoices, guarantees and photographs before work was covered
• Building Regulations records for replacement roof coverings or structural alteration where applicable
• Leak, storm, flood and insurance-claim history, including rooms affected and recurrence after repair
• Any asbestos survey covering cement sheets, soffits, fascias, gutters, downpipes or roof-space materials
• For solar equipment, installation, roof-fixing, electrical and Building Regulations records
• For flats, management records, planned major works, reserve funds and responsibility for roof, façade and drainage
• In leasehold property, the roof, external walls and shared drainage may be managed and charged through the freeholder; inspect the lease, service-charge history, reserve fund and proposed major works with your conveyancer.
• A surveyor's access to a flat's roof or communal areas may be limited. Agree who will obtain access and how uninspected elements will be reported.
• Listed-building consent or conservation-area controls may affect roof covering, chimney, gutter and downpipe repairs or replacement; like-for-like appearance does not itself settle consent.
• Older roofs and traditional materials need a surveyor and contractor experienced in that construction, not a generic replacement assumption.

Red flags and limits

• Loose, hanging or recently fallen roof, chimney, gutter or façade material. Meaning: There may be a falling-object hazard and hidden damage. Next: Stay outside the drop zone and seek prompt competent roofer or structural advice.
• Active internal leakage, bulging ceiling, rapid staining or water near electrics. Meaning: The immediate internal hazard takes priority over finding the external source. Next: Keep clear and arrange urgent building, roofing and electrical help as applicable.
• Recurring gutter overflow, water running behind the gutter or discharge wetting the wall. Meaning: Rainwater management may be defective, but the cause is not established. Next: Request a safe-access rainwater inspection and any needed drainage investigation.
• Roof areas are hidden, inaccessible, recently coated, covered by solar panels or affected by undocumented spray foam. Meaning: Important fabric may not be inspectable by ordinary visual survey. Next: Agree additional inspection scope with the surveyor and the appropriate roof or moisture specialist.
• Broken cement-like sheet, soffit, gutter or downpipe debris is present. Meaning: Asbestos cannot be ruled out by appearance. Next: Do not touch or clear it; seek competent asbestos assessment and coordinated roof repair.

Decision options

• Options only: True
• Proceed: An option where the agreed survey scope gives an acceptable account of visible roof and drainage condition and no material inaccessible or unresolved issue remains.
• Seek specialist: Use this option for active leaks, flat or unusual roofs, chimneys, hidden drainage, solar installations, suspected asbestos, spray foam or any area the surveyor cannot inspect.
• Renegotiate: An option only after written findings and comparable scopes define the work; photographs do not determine remaining life, repair cost or value.
• Valuation boundary: No roof observation, quote or guarantee on this page is a valuation or a promise of a price adjustment.
• Capture safe ground-level views by elevation and weather.
• Request roof, drainage, alteration and leak records.
• Tell the surveyor about every hidden area and specific concern before inspection.
• Obtain specialist safe-access evidence where the survey cannot reach a conclusion.
• Use documented scope and quotes for any proceed or renegotiate decision.

Survey and professional route

• Overall roof condition and relation to internal defects Professional: An independent building surveyor experienced in the roof type Reason: To integrate roof, structure, moisture and access limitations.
• Close roof, chimney, gutter or flat-roof inspection Professional: A competent roofing contractor using planned safe access Reason: The buyer must not climb or use a high ladder.
• Below-ground or shared drainage concern Professional: A competent drainage contractor and the conveyancer or water company where ownership is unclear Reason: Surface ponding cannot locate a restriction or establish responsibility.
• Possible structural movement or unstable chimney Professional: A structural engineer Reason: A photograph cannot establish stability.
• Unknown cement-like materials or debris Professional: A competent asbestos surveyor, coordinated with the roofer Reason: Material identification and disturbance planning are professional work.

Stay off roofs, ladders and guttering

• HSE's work-at-height hierarchy starts by avoiding work at height and doing as much as possible from the ground, for example with extendable tools. [2]
• HSE says you are working at height if you are on a ladder or a flat roof, or could fall through a fragile surface. If this task needs roof access, a high ladder, guttering access or improvised access, stop and use a competent contractor. [2]
• Do not go onto a roof, lean a ladder on guttering, or use furniture or another improvised platform. This page does not teach ladder setup or roof walking. [2]
