Flat roof waterproofing

Protection against water with attention to drainage. A flat roof can leak because of failures at critical points, ageing layers, open joints or poor drainage. The source doesn't always match where the leak appears.

What problems we deal with in this job

Ponding water, cracked parapets, faulty flashings and deterioration around equipment all matter.

An accurate quote describes which areas will be inspected and which could hide damage that is not yet visible. At Build Ararat we don't promise a permanent repair without knowing the cause and the condition of the materials.

What we check before proposing the work

We check drains, falls, junctions with chimneys and equipment, existing layers and ease of maintenance.

For a first enquiry we recommend sending photos from different angles, the town, the approximate number of floors and the history of the problem. This information helps us prepare the visit, but photos cannot certify the condition of a facade or the safety of its anchors.

Waterproofing

How it can be solved

Treatment may involve local repairs, renewing the waterproofing system or more extensive repair of falls and insulation where they are damaged.

Tools, products and the access system are chosen according to the substrate and the conditions of the job. Rope access, suspended scaffolding, tube scaffolding or a platform can be used where appropriate; no technique is universally better than the others.

What can go wrong if only the appearance is fixed

Sealing only the stain inside does not stop rain getting in through the roof.

On exterior elements we also need to check how water drains away, how the joints behave and what maintenance the finish will need. Preparation and details often determine whether a stain, a crack or a flaking layer comes back.

How the quote for flat roof waterproofing is prepared

There is no single responsible rate for every building. For this job the key factors are: height and actual access to the area; surface area and measurements; condition of the substrate; preparation and protection of third parties. To compare proposals, it helps to list materials, labour, safety measures, access equipment and exclusions separately. See how to request a detailed quote.

Frequently asked questions

Can a roof be repaired without taking it apart?

Some points can; if there is damage beneath the system, it may need to be opened up.

Do drains need to be kept clean?

Yes; regular cleaning helps prevent ponding.
