Industrial roof coatings in Chichester: survey first, always
We’ve worked on plenty of industrial buildings around Chichester, from the trading estates on the edge of town to the workshops and storage units further out. Most of them have profiled metal roofs that have been in service for a good twenty years, or more. We specialise in industrial roof coatings across Chichester and the wider West Sussex area, and every single job starts with us getting up on the roof. We won’t quote off satellite images because the condition of the sheets, the laps, the fixings and the cut edges will tell us if a coating is the right call at all.
For anyone running a site or managing an estate, coating a roof instead of replacing it has a clear appeal. If the roof is sound, we can protect it and add years to its working life without stripping the building back to its frame. That means no major disruption, and none of the cost and downtime that re-sheeting brings. But that word “sound” is the key, and that’s what our survey establishes.
Coastal air and what it does to profiled metal
Chichester sits close to the harbour and the open coast, and that salt-laden air is much harder on external metalwork than an inland climate. The factory finish on profiled steel sheets weathers gradually over time: it chalks, the colour fades, and eventually the coating thins until moisture reaches the steel underneath. Once that happens, corrosion stops creeping and starts accelerating. A roof that looked merely tired at the last inspection can be showing rust staining and edge delamination within just a couple of seasons.
An industrial roof coating stops that process before it gets that far. We apply it to a prepared, sound substrate, and the system restores a continuous weatherproof layer across the whole roof. It seals the laps and fixings, and stops that slow cosmetic decline from turning into full-blown sheet failure.
Factory roof painters around Chichester are judged on their preparation. Rust treated and laps sealed first is what separates a lasting job from an overpaint.
Cut-edge corrosion: the fault we find most often
On almost every profiled metal roof we survey, the first place we see deterioration is at the cut edges. These are the exposed ends of the sheets at the eaves, laps and verges, where the steel core has no factory coating to protect it. Moisture wicks into the overlap, rust forms along the edge, and over time it tracks back beneath the finish and lifts it. Left alone, cut-edge corrosion is what turns a coating project into a re-sheeting project.
Catch it early, and it’s very treatable. We mechanically prepare the affected edges, treat them, and seal them with a dedicated cut-edge system before the main roof coating goes on. It’s detailed, unglamorous work, and it’s the part of the job that dictates how long the rest of the system lasts.
Working around a live site
Most of the buildings we coat in Chichester are occupied and trading, and coating works well in that situation because all the work happens on the outside. There’s no strip-off, no exposed deck overnight, and no need to clear racking or move production. We always plan the practical details with your site team before anyone arrives:
- We schedule access around deliveries, shift patterns and yard movements.
- There are no hot works in standard coating application.
- We give occupiers and site managers clear notice of each phase of work.
- We sequence the work area by area so the roof stays watertight throughout.
- The site is clean and operational at the end of every working day.
When coating is not the right answer
We won’t coat a roof that needs to be replaced. If our survey finds widespread perforation, or corrosion that has weakened the sheets or their fixings across large areas, or saturated insulation within a built-up system, a coating would only hide the problem and waste your budget. The same applies where persistent ponding is caused by structural deflection: no coating corrects a roof that no longer falls the way it should.
In those cases, we’ll tell you plainly and put it in writing. That way, you’ll have an honest condition report for your maintenance planning, whichever contractor ends up doing the work. Where the roof is sound, or sound enough once we’ve dealt with the cut edges and isolated defects, coating is usually the most economical way to keep an industrial building in Chichester dry for years to come. Our survey tells you which side of that line your roof sits on.
