How do you handle itemised quotes?
Do you manage building regulations?
We provide fully itemised, transparent quotes with fixed structural costs. We do not use lowball estimates; every cost is detailed before work starts on-site.
Yes. We handle all local authority building control notices, structural calculations, and inspector visits across Greater Manchester, ensuring full legal compliance.
What roofing guarantees do you offer?
What are your typical project timelines?
All new roofs and major roof repairs carry comprehensive structural guarantees. As Rochdale-rooted master builders, our family name stands behind every slate and timber.
Timelines depend on structural complexity. A standard house extension takes 8 to 12 weeks, while a full re-roof is completed in 5 to 7 days, weather permitting.
