All you need to know about replacing a bargeboard including costs of materials, costs of labour and time frames.
Bargeboards are the roofline products which are located on a gable end of a house and are usually made from timber or Upvc plastic. They hide the otherwise exposed roof rafters from the elements, stopping rainwater from getting into the roof and rotting the rafters. Timber bargeboards will eventually rot, even if regularly painted, so at some point they will need to be replaced.
In most cases this will mean a scaffold tower being erected to the desired work height, removing the edge roof tiles, then existing bargeboard using a crowbar. As long as the rot has not spread to the roof rafters, new Upvc plastic or timber bargeboard can then be fitted and the roof tiles put back in place. If fitting a new timber bargeboard, then this will also require painting on a regular basis to prolong its lifespan, but uPVC products are essentially maintenance free.
Whenever any of the roofline products are being replaced, it makes sense to consider replacing the rest of the timber roofline products (fascia and soffit) plus the guttering too, as this will often have to be removed/refitted in any case. While you are up at the roofline with safe access, you should also consider cleaning out the guttering and inspecting the roof tiles for any missing or damaged shingles at the very least. The rafters should also be inspected before replacing bargeboard and any rot should be treated/removed as a priority. You may also consider having the gable end repointed if necessary while the scaffold is in place.
Repairs can be made to isolated areas of the bargeboard, but there comes a point when it is simply not worth repairing and should be completely replaced. You can do this job as a DIY project, it is not terribly complicated, but you may change your mind once you realise just how time consuming this job can be!
Replacing the bargeboard involves erecting a suitable scaffold that meets your local council requirements, removing any verge tiles and the sand and cement pointing (checking first that this does not contain asbestos), then once you have removed the verge tiles and bedding you can then start removing the bargeboard using a pry bar to pry away the barge from the rafter. Once bargeboard is removed, then fit the new timber or uPVC bargeboard ensuring that all four edges are sealed and undercoated (if timber). Then refit the roof tiles and bedding. Finally, disassemble the scaffolding and remove all waste from the site. It’s a fairly simple but time consuming job.
Working at heights can be dangerous for everyone, but especially for those that have vertigo or a fear of heights. Unless you are confident working at height, bargeboards should probably be left to a professional to remove safely using scaffolding. In addition, it is not unusual in older properties to find asbestos in the eaves. Asbestos is a carcinogenic compound that was once used as a building material for its ability to absorb heat. Asbestos needs careful handling and disposal to avoid disastrous consequences, but unless you are an experienced tradesman, you probably will not be able to even identify asbestos if you find it?
This is one of those jobs that is probably best left to professionals to do safely, once you factor in the cost of the scaffold and the amount of time it will take you to complete, you really do not save that much over hiring a professional in the first place!
The average cost of hiring someone to replace a bargeboard is usually in the region of £500-£750 depending upon if you want your soffit boards replaced as well, and whether or not any timber needs repairing/treating, and if some tiles need to removed and then re-cemented.
Most roofline tradesmen charge around £150 per day and it will normally take 2 tradesmen around 6-8 hours to set up the scaffolding and replace the bargeboard.
