What this service includes
Service Overview
Salt air, wind-driven rain and “unwashed” areas make coastal homes hard on materials. Trevor treats durability as a whole-system problem: correct product selection for the local corrosivity, compatible fasteners, smart edge/lap details and realistic maintenance access. Calm, practical advice; tidy execution; long-life outcomes.
What You Can Expect
- Right product for the zone — claddings/roof sheets chosen for your site’s marine exposure (distance to breaking surf, wind, topography).
- Compatible fasteners & accessories — avoid galvanic mismatch; specify fixings that suit the base metal and coating.
- Edge & lap detailing — protect cut edges; design penetrations, flashings and terminations to shed water.
- Unwashed areas strategy — plan rinsing access for soffits/underlaps so salt doesn’t accumulate.
- Maintenance that’s doable — simple clean/inspect intervals and access that trades (and owners) actually use.
In short: we match materials to the coast, detail the weak points, and make maintenance practical — so your home ages well, not fast.
Where This Service Fits Best
Common on surf-exposed or bayside sites in:
Niche cross-overs we handle
- Roofing & coastal exteriors — re-sheeting, flashings and profiles that suit the corrosion plan.
See: Roofing & Coastal Exteriors - Complex rooflines & box-gutters — internal gutters and parapets sized with proper overflow paths.
See: Complex Rooflines & Box-Gutter Remediation - Leak & draft diagnostics — thermal imaging + blower door to expose hidden water/air paths before you spend.

FAQs
-
How close to the beach changes what I can use?
Proximity to breaking surf and local wind exposure drive product choice and coatings; we specify accordingly. -
Do I need stainless fixings everywhere?
Not always. We select compatible fasteners matched to the base metal/coating and the site’s corrosivity. -
What are “unwashed” areas and why do they matter?
Sheltered surfaces (e.g., soffits/underlaps) don’t get rain-rinsed; salt builds up faster there. We plan access and detail edges to cope. -
Will mismatched metals really corrode faster?
Yes — galvanic pairs can accelerate attack. We avoid risky combinations and control water run-off between dissimilar metals. -
Can this help warranties?
Using the right product for the environment and maintaining it properly protects performance and keeps manufacturer warranties in play. -
Will new cladding match the old roof?
We coordinate profiles, colours and trims; where needed we stage works so the look reads as one building. -
What about roof drainage and box-gutters?
Durability fails if water can’t exit — we size gutters/downpipes and provide overflow paths to code intent. -
How long does a coastal upgrade take?
Often 1–3 weeks once access and materials are set; complex re-sheeting or interface work can extend timelines.
