Fix Loft Condensation, Hetton

Building regs (Part F) say the roof needs a specific area of ventilation per metre of eave and ridge. Most Hetton homes built before 2010 fall short — we bring them up to spec in one visit. We're regularly on roofs close to the A182, through Easington Lane and Eppleton.

  • Eave vents (over-fascia continuous strip, or discrete vent tiles)
  • Ridge vents — either full continuous or spot ridge-vent tiles
  • Tile-mounted through-vents mid-slope for hipped roofs
  • Underlay lap vents if the felt underlay is fully lapped and sealed
  • Damp-meter survey at the start so we can prove improvement after
  • Part F Building Regs compliance on completion

Insulation without ventilation is the problem

Topping-up loft insulation to 300mm is great for heat loss but wrecks the roof if the ventilation isn't upgraded to match. We fix them as a pair, not one at a time. We survey with a damp meter into the timbers, not just eyeballing the felt. Two rafters that look identical can be reading 12% and 25% moisture — the second one needs action.

Signs your Hetton loft is under-ventilated

Black mould spots on the underlay, damp-smell in the loft hatch, moisture beads on the felt on a cold morning, staining running from the eaves onto the ceiling below. Any one of those means airflow is failing.

Roof ventilation in Hetton — FAQs

How much does a full ventilation upgrade cost?+

Typical semi with over-fascia vent and dry-ridge conversion: £700–£1,400 depending on scaffold. Individual tile-vent additions from £150 each fitted.

Will this stop black mould in the loft?+

Yes, provided the underlying source is condensation (not a roof leak). We check with a damp meter first so we're fixing the actual problem.

Is a mechanical fan (PIV) needed as well?+

Sometimes — if the house has severe living-space condensation, a PIV unit in the loft complements roof-side vents. We flag it if we see it; we don't force-sell it.

Do you cover Hetton?+

Yes — DH5 in full.
