Asphalt and wood shingle roofs remain a popular choice across New Zealand for their classic appearance and reliable weather protection. Both materials are designed to shed water effectively when installed correctly and kept in good condition.
Over time, however, shingle roofs age gradually through granule loss, curling edges, cracking, and moisture absorption, all part of the natural wear cycle. Left untreated, these small signs of ageing open the door to leaks, rot, and increasingly costly repairs, which is why addressing them early makes such a difference to the long-term life of the roof.
Our Shingle Roof Coating Process
Roof Inspection
We assess the condition of the shingles across the whole roof, checking for curling, cracking, granule loss, and any areas of timber that may have started to soften or rot, particularly on wood shingle roofs.
Cleaning and Preparation
Moss, lichen, and built-up debris are cleared from between and underneath the shingles, since trapped moisture and organic growth are common causes of premature shingle failure if left in place.
Repairs
Loose, cracked, curling, or missing shingles are secured, re-fixed, or replaced so the roof forms a complete, stable surface before coating begins.
Priming
Primer is applied where required, particularly on wood shingles, to help the liquid coating bond properly to a naturally absorbent and uneven surface.
Membrane Coating Application
The liquid membrane coating is applied across the full roof, sealing gaps between shingles and forming a continuous waterproof layer that protects against further moisture damage and extends the roof’s usable life.
Signs Your Shingle Roof Needs Attention
- Curling, cupping, or lifting shingle edges
- Bald patches where protective granules have worn away
- Cracked or split shingles, especially on sun-exposed slopes
- Moss or dark staining building up between shingle rows
- Soft, spongy, or discoloured timber on wood shingle roofs
