External Maintenance

Block Maintenance

External works
Property needs to be protected from Normal wear and tear (and this is a specific exclusion of most insurance contracts and many claims are rejected on the basis that damage was more directly caused by poor maintenance rather than by an insured peril)

Insurance should never be seen as an alternative to good risk management.
Routine, ongoing and preventative maintenance will not only help keep a property in a good state of repair but will also help make a property more resilient to potential losses.
Neglecting routine building maintenance will often result in the need for costly and more disruptive remedial work. This guide provides a checklist to help you protect your property, and to help establish a regime of good preventative maintenance. (see page 3 for checklist).
Building Inspections
Regular and systematic building inspections are a key part of any maintenance programme in order to help identify problems promptly. Early remedial action by a competent contractor is essential to prevent further, more costly, damage.
It may also be necessary to engage a competent person with the appropriate skills and equipment to carry out inspections in certain areas e.g. roofs.
Intervals between inspections may vary depending on such things as the location, age, construction, usage etc. of a building.
Log books are indispensable for keeping track of maintenance regimes, identified problems and actions taken.
External Building Fabric
The fabric of a building needs frequent and careful examination particularly when in an exposed or elevated location.
Roofs need to be inspected at least twice a year or following particularly stormy weather – debris on the ground from broken slates and tiles indicates that there is a problem. In some cases roofs can be inspected using binoculars or vantage points from nearby higher buildings.
Repair or replace:

Missing, slipped or broken slates or tiles

Damaged or rusty cladding

Cracked flat roof coverings. A bitumen roofing felt may need to be completely renewed after 10 years.

Leaking or damaged rooflights

Damaged flashing

Gaps and missing mortar between ridge tiles
In addition moss, which retains damp, needs to be removed since it can cause slate to delaminate and can gradually erode all metals particularly lead work – a seasonal brushing down is often all that is required to prevent excessive build up.
Where puddles occur on flat roofing advice should be sought from a qualified building surveyor.
If safe to do so, additional inspection through the loft access may show daylight or water penetration which is not always apparent from external examination.
Apart from cleaning twice yearly repair or replace:

Damaged flashing

Damaged mortar
Lightning Conductors
Any lightning conductor systems need to be checked and maintained every 14/15 months by a suitably qualified and experienced person to ensure that they are undamaged, continue to conform to the relevant standards and provide the protection for which they were designed.

Blocked or damaged rainwater removal systems
will allow damage to the building fabric or water
ingress. The underground drainage system also
needs to effectively remove water away from the
property and not become blocked with leaves, silt,
vegetation or grease.
Trees can cause building movement and damage
by removing moisture from the ground and
conversely if removed when mature by allowing
soils to expand. In addition tree roots notoriously
