Coastal roofs age faster than inland ones, but a simple annual routine catches most problems before they become leaks. Here's the checklist we work through on every maintenance plan visit.
1. Clear gutters and valleys
Leaf litter and salt-caked debris block gutters and valleys, forcing water over the edges and into the roof. On a coastal home with overhanging trees, this needs doing at least once a year — twice if you're beachfront with nearby pandanus or coastal scrub.
2. Check all fixings
On a metal roof, look for rust around screw heads, backed-out screws and perished washers. On a tile roof, check for cracked, slipped or broken tiles. A handful of failed fixings is normal over time; the goal is to catch them before water gets in.
3. Inspect flashings and sealants
Flashings around chimneys, skylights, vents and where the roof meets a wall rely on sealants that perish in UV and salt. Cracked, shrunk or missing sealant is a leak waiting to happen. Re-seal with a coastal-grade product.
4. Check ridge capping (tile roofs)
Look for cracked mortar and gaps under ridge caps. If the pointing is crumbling or cracking, a repoint is due. Flexible pointing compound lasts far longer than rigid mortar.
5. Look for rust at laps and cut edges (metal roofs)
Colorbond fails first where the coating is exposed — cut edges and sheet overlaps. Orange staining at the laps means cut-edge rust is starting. Treat it early with a rust converter and sealant; it's cheap. A rusted-through sheet is not.
6. Check the ceiling space
From inside, look for water stains, damp insulation or a musty smell. These are often the first sign of a roof leak, and they tell you roughly where on the roof to look.
7. Photograph and record
Take a few photos each year and keep a note of anything you flagged. A year-on-year record makes it obvious when something's changed, and it's gold for insurance or warranty claims.
