FAQs — Farnworth
Do you work on bungalows and dormers in Farnworth?
Yes — both are bread-and-butter for us, particularly in BL4 where bungalows and dormer extensions are common.

Usually yes for repairs and most flat roof jobs. Full re-roofs typically have a 2-4 week lead time depending on scaffold and material availability.
How do I know if my Farnworth slate roof has nail sickness?
You'll see slates slipping across multiple rows, not just one spot — often after each storm. It means the iron nails are corroded and the whole roof is due a strip and re-slate.
Welsh or Spanish slate — which do you use in Farnworth?
Both. Welsh Penrhyn is longest lasting (100+ years) but the priciest. Spanish SSQ-grade is 60-80 years and around 40% cheaper. On densely packed victorian terrace stock, strong demand for re-roofs on 1900-1920 housing. we'll quote both so you can choose.

Depends on the pitch and exposure. Stainless steel nails on most standard BL4 roofs; copper slate hooks on exposed sites or where slates need to be visible-fixed at the eaves.

Typical mid-terrace: 4-6 working days with scaffold, plus a day either side for set-up and strike. Semis and detached usually 5-8 days.
