Terracotta Roofing

Besides its visually pleasing aesthetic, the humble terracotta roofing tile has been around for many years. Terracotta (also know as clay tiles) tiles are a fired product. Therefore are non-porous meaning they require less maintenance to the tile surface than the cement counterpart. Like any other building material that is exposed to harsh Melbourne weather day in and day out, your roof will require a terracotta roof restoration from time to time.

 

Signs of Damage on a Terracotta Roof

 

When we are inspecting a terracotta roof, we look for signs of deteriorating cement, extreme Lichen growth, large gaps in tiles, surface damage or flaking of the roof tiles, misaligned roof tiles and or ridge capping and obviously any know leaks.

 

Deteriorating Cement:

Any cement that is falling out of place or loose on the roof is the result of age and lack of maintenance. Ridge tiles that have slipped down from the hips will also be a sign that the flexible pointing has ceased to be and effective method of holding down the ridge capping. This may be confined to certain areas of the roof however the rest of the cement and ridgecapping will definitely be heading in that same direction. It is necessary that all the bedding be repaired and new flexible pointing be applied to ensure that all cement work and ridging remains sound.

 

Lichen Growth:

Lichen or moss often does not pose a threat to your roof. It is only when the algae gets so thick that it actually grows behind and blocks the water course channels of your roof tiles. In this instance, a pressure clean will need to be completed to remove the moss.

 

Roof Tile Gap:

Often your tiles will eventually shift and the gaps or joins will get larger. This is especially true if the roof is in a windy or elevated area. Also over time, the tiles tend to warp slightly and change shape. This is not usually a problem but occasionally your tiles will need to be moved around and re-aligned.

 

Surface Damage:

A terracotta roof tile is susceptible to flaking. This happens if the surface breaks down. Quite often this will happen in coastal areas because the salt. The tiles and ridgecapping almost looks like they have a disease and require to be changed.

 

Terracotta Roof Restoration Process

 

Firstly your roof is inspected before any roof restoration takes place. We determine what is required for your full restoration. a quotation is submitted and then returned to our office by the customer so that work can commence.

  • Our first step is to install the handrail as required. We use handrail on 95% of our jobs.
  • After the handrail is set up, we will start the repairs to the cement work of the ridge capping.
  • After this, we will pressure clean the roof down. We then tidy up all the mess created.
  • Then we will continue on with the repair work of the cement. We change any valley iron or flashing required and fully point / re-point all the ridge capping, valleys and gables.
  • We then apply a Terraglaze high gloss seal which dramatically improves the look of the roof, protects the tile and inhibits the re-growth of algae.
  • Finally we blow down the roof, clean the gutters, and remove the hand rail.
