Top tips
Hiring a soffits, without the regret.
Four moves that separate a smooth job from a nightmare.
Vented or solid — never one of each.
Mixing vented and solid soffits around the same loft creates an air-pressure dead spot. Specify the same type all round.
Replace the felt edge tray too.
Behind the fascia is a felt edge tray (eaves support). Often rotten. Insist this is replaced when soffit work is done — it's the difference between 5 and 20 years.
Match the colour to the property.
Pure white soffits look stark on red-brick houses; rosewood or anthracite read better. Soffit colour is a decade-long decision — get a sample on-site.
Check the loft vents are clear.
After soffit replacement, look in the loft — you should feel airflow at the eaves. Blocked vents = condensation + rotting timbers.
