There are two main types of PVC fascia/soffit systems available on the market, and M J Faint Roofers have experience with both of these.
These are a 10mm “cappit” system that is used over sound existing or new timber and an 18mm solid replacement system that is used once rotten/unsound timber has been removed.
The most common finish colour is gloss white, but other colours are available in shades of brown and black, some of which also have a wood-grain finish. Fascia details include moulded finishes to replicate those found in timber and whatever your requirements there will be a suitable system that can be used.
PVC guttering and down-pipes are available in a variety of shapes and colours. These can be used to replace existing guttering, either on timber fascia or one of the PVC systems above. There are many design options and M J Faint Roofers can advise which is most suitable for any given project.
