Horizon Pop Top - Experience

Sorry you are having these issues. Seems strange that others are not. WHy not post some pics of the issues you are having, then others can comment?
Thanks. Collecting information first if that’s ok, trying to be only fact based…if anyone with a Horizon or HiLo roof has no problems, or problems DM me…won’t be asking leading questions / photos, only for comparisons. Will post photos & findings once I’ve got all the information together and a way forward agreed.

I was only suggesting you post photos of the issues then people could post photos of the same parts of their roofs for comparison, rather than just random pics that might be no use.
 
Update from meeting / water tests / gutter inspection / comparison:

Very productive and positive…

Appears leaks (roof top and gutter) may be a result of supplier (Horizon) remedial works to reprofile roof top (on receipt roof was significantly concave / ponding-since reprofiled by Horizon is much better)…So likely needs some sealant at canvas junctions to make good. Leaks occurred after reprofiling.

Then compared our Horizon roof to another LWB (HiLo) the installer fitted a number of years ago (note doesn’t leak, and installer hasn’t experienced any HiLo or Horizon leaks to date (except one roof needing a minor repair to sealant)).
It’s not been noted before: same bow / fall to gutter outside / frame / lip / roof trim inside as our roof (ie water will collect / pond at centre of gutter if sat perfectly level)…drainage impacted further by outlets, hinge width etc.

Ultimately confirmed it’s not a deviation and as manufactured…our gutter ponds water, which then sits against canvas, which is folded under at base of gutter. Yes canvas is coated (‘water resistant’), it’s still a canvas, with sealant junctions at base of gutter (ie not a ‘waterproof’ upstand…suitable for purpose??)

Likely to have exacerbated the leaks I’m experiencing, although for me even if re-sealed, gutter design doesn’t function robustly (ponds water against canvas / canvas junctions)…so next stage is hopefully working through some design solutions through our installer and with supplier.

I do think, from my own recent separate questions and feedback, Horizon have very significantly improved and tightened their approved installer network from previous and now mostly historic HiLo installer directed installation issues (eg our installer very competent, has installed well what they have been provided-and hence me not naming as will likely be unfairly attributed all the blame!). Therefore based on my own current experience of the drainage / roof in use, next talking through how possibly a few design adjustments / historic design issues (again not blaming supplier…was inherited) need some attention to create a more robust product and where necessary a retrofit solution (rains lots, needs robust drainage+waterproof drain=dry van!)

Will keep posted.

Hi @oldgoat - how has all this panned out for you? I am still looking to get a horizon poptop fitted - but still holding to see if they have sorted your issues.

Hi, still ongoing…

With installer and supplier identified and agreed some design and manufacturing issues, they’ve carried out some upgrades and repairs, and whilst moving forwards, more yet to be done to rectify and resolve.

Will keep posted.

Ongoing update…moving forward collaboratively with installer and supplier:

Van to go back to Horizon for some redesigned and replacement elements including pop up roof and whole canvas, plus improvements to drainage and gutter detailing.

Need to agree and finalise, with some design revisions yet to be worked out / clarified…

Target to have all complete by Feb 2025. Will update then!
 
I hope you have inspected, seen and used in typically wet conditions and operated - and are aware that its confirmed that the pop top roof can pond water, main roof integral frame bows down, gutters pond water (insufficient number, size and location of outlets), canvas is sat in gutter (which ponds water).

Fingers crossed for you.
