New Build Warranty · Liss
Liss roof — new build warranty done properly
The property is two or three years old, the developer has left, but the roof is already showing early algae streaks and a couple of ridge tiles that never quite got fixed properly at build. Nothing is dangerous, but everything is easier to sort while the NHBC or LABC warranty and the developer snagging period are still live.
The property is two or three years old, the developer has left, but the roof is already showing early algae streaks and a couple of ridge tiles that never quite got fixed properly at build. Nothing is dangerous, but everything is easier to sort while the NHBC or LABC warranty and the developer snagging period are still live. We deal with this weekly across Liss and the wider East Hampshire District, and it's genuinely one of the more solvable roof problems if it's caught in the right window.
The sequence that actually works
- Get a photo survey done while the two-year snagging window is still open.
- Log every defect back to the developer in writing with dated photos.
- Book a soft-wash and biocide pass to stop algae becoming permanent staining on porous new concrete tiles.
- Check gutter alignment and downpipe outlets — new-build uPVC often shrinks and separates after its first hot summer.
- Keep the report on file so the year-10 structural warranty conversation is documented.

Red flags — act this week
- developer defects not yet closed out and the warranty clock ticking
- obvious algae streaking within three years of the build handover
- gutter joints that have already visibly separated
- loose or under-torqued dry-fix ridge and hip fixings
Realistic timeline
Survey and clean typically finish inside 2–3 weeks; any developer snag then runs on the developer's own timeline.
The money reality
This is the cheapest maintenance window of the roof's whole life — spend a little here and you set up 15–20 years of low-cost ownership.
What happens if you ignore it
The two-year snagging window closes, the developer walks away, and everything you might have got fixed for free becomes yours to pay for.

Frequently asked
Will cleaning affect my NHBC or manufacturer warranty?
No — soft-wash at the pressures we use is compatible with every major tile manufacturer warranty, and we log the visit in writing so there's a defensible record. In Liss specifically, we can normally survey within the week thanks to our regular round through Petersfield and Liphook.
Can you help me raise a developer snag from a survey?
Yes — the photo report is formatted to drop straight into the developer's snag process and the NHBC's paper trail. In Liss specifically, we can normally survey within the week thanks to our regular round through Petersfield and Liphook.
Do you cover Liss for new build warranty situations urgently?
Yes — Best programmed toward the end of year one or year two — while snagging and warranty escalation is still straightforward. We prioritise same-week bookings for Liss when the situation is time-sensitive.
