Onduline Roofing Loughborough — Lightweight, Watertight Roofs Built to Last

How Long Does an Onduline Roof Last in Loughborough?

A well-fitted Onduline roof lasts around 15 years in Loughborough's climate. Onduline's own waterproofing warranty runs 15 years when sheets are fixed to instructions. The sheets are BBA approved, and with proper support and airflow, many roofs comfortably reach — or pass — that mark.

Three things protect its life:

• Fixing to a full deck or correctly spaced timber purlins
• Genuine Onduline nails or screws in every corrugation at the laps
• Clearing moss, leaves and gutters each year

Wrong purlin spacing or the wrong fixings cut that life short. We check the deck and framing first, then sheet the roof the right way.

That mix of low weight, low cost and long life is why it's the go-to cover for garages, sheds and stables right across Leicestershire.

Pick the Right Onduline Roof for Your Loughborough Building

Onduline weighs little, so it works on timber frames that cannot carry heavy tiles. Homeowners in Loughborough choose it for garages, sheds, stables, workshops, summerhouses and farm buildings.

It is a smart pick for outbuildings and low-pitch roofs. It is not a like-for-like swap for a tiled house roof on a front elevation. We tell you plainly which jobs it suits and which it does not.

Wind matters here. On exposed ground near Beacon Hill Country Park, sheets need full fixing and tight laps. Fixed correctly, Onduline holds firm through the storms that roll across the Soar Valley.

the roof watertight while leaving the asbestos safely encapsulated underneath. It saves you money and skips the hazardous strip-out.

In Shepshed and Quorn, we see plenty of leaking felt roofs on outbuildings. The damp, wooded pockets around Charnwood rot weak boards fast, so the deck check is never skipped.

Get Pitch and Fixings Right for a Watertight Onduline Roof

Pitch decides the method. Onduline needs a 5-degree minimum pitch. Below 10 degrees, the sheets must sit on a full supporting deck. The lower the pitch, the more overlap each sheet needs at the sides and ends.

Support matters just as much. On a battened roof, battens sit at around 450mm centres so the sheets can't sag between them. On shallow roofs, we board the whole surface first. Skimp on either and the bitumen droops in summer heat — the single most common cause of a tired-looking Onduline roof.

Fixings do the rest. We fix every corrugation at the eaves, the overlaps and the ridge. Genuine Onduline nails or screws carry a wide washer that keeps the holes

watertight for years.

Many garages around Barrow-upon-Soar sit at a shallow pitch. We deck those roofs fully and set the laps wider, so water runs off and never tracks back under the sheets.

• Onduline vs Coroline: They fit the same way and look similar. Onduline is thicker (3mm), BBA approved, and holds up better on exposed or larger roofs. Coroline is a touch lighter and cheaper for small, sheltered jobs.

We don't push the priciest option. We spec what actually suits your building and your budget, then put it in writing.

Stop Condensation and Drips Under Your Onduline Roof

Drips inside an outbuilding are often condensation, not a leak. Warm, damp air rises, hits the cold underside of the sheet, and forms water droplets. Cold roofs with no airflow suffer most.

We fix this with airflow. Vents at the eaves and ridge let moist air escape before it settles. You may see a black, tar-like tint in early droplets. It carries no harmful content, but it can mark stored items, so we sort the airflow properly in Loughborough outbuildings.

Still, cold nights across the Soar Valley raise the dew-point risk on shallow roofs. Good ventilation, set at install, keeps the underside dry through winter.

Repair or Replace a Sagging, Faded or Leaking Onduline Roof

Sagging usually means the sheets lacked support. Purlins set too far apart let the bitumen droop in summer heat. We re-fix or re-support the sheets, or replace the failed runs where the sag has set in.

Fading is cosmetic. The colour softens with sun over the years, but the sheet still sheds water. A leak, though, points to loose fixings, worn laps or an ageing roof at the end of its life. We find the real cause before quoting a fix.

Across Sileby and Mountsorrel, older shed and garage roofs often reach this stage together. We tell you straight whether a repair will hold or a full re-sheet is the better call.

Check Fire Rules and Building Regs Before Work Starts

Fire rules matter near a boundary. Onduline is not rated to the External S.AA fire class that some structures need. Close to a neighbour's building, the sheets must sit on a full deck and take a surface treatment to meet the rule. We flag this before we quote.

Building regulations can apply to larger re-roofs, and conservation rules apply to period homes. In Woodhouse Eaves and other Charnwood conservation spots, a planning officer may refuse Onduline on a roof seen from the street. We check the position for your Loughborough property first, so there are no surprises.
