Rooflight leak repairs in St Ives

Leaks and misting around a rooflight tend to come from a short list of causes. Sealant that has cracked or pulled away. Flashing or membrane that has perished at the edges. Condensation channels blocked with dirt, so water backs up inside the frame. Ponding water lying against the kerb because the roof falls the wrong way. Or a sealed glass unit that has failed and misted between the panes. Our rooflight leak repairs visits in St Ives work through these in turn, with the visit priced before booking.

Covering PE27 and neighbouring districts

Jobs across PE27, PE29 and CB24 are part of our normal cover for St Ives. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Huntingdon and St Neots are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

What the job includes

  • Rotten kerb sections replaced where the timber has gone soft
  • Lifted flashing or tape removed and renewed
  • Inside check of stains, frame drainage channels and the reveal
  • Water lying against the kerb — We check whether rainwater sits against the upstand after it stops raining.
  • Upstand height and condition — We measure the kerb and probe the timber for softness.

How a repair visit goes

Most of the effort on a repair visit goes into finding the cause. We start with your account of when it leaks: heavy rain, wind from one direction, or cold mornings, which points towards condensation. That shapes where we look first. Findings are photographed so you can see them for yourself. You then get a clear explanation and, where needed, a written repair quote, fixed before anything further is booked.

Do you need permission in St Ives?

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

What to send us

Tell us where the water appears, how long it has been happening and what the weather was doing when it started. A couple of photos from inside and outside, plus the postcode, let us price the visit before you book and plan what the fitter brings.

Common questions in St Ives

Why is my rooflight leaking?

The usual causes are sealant that has cracked or pulled away, flashing or membrane that has perished at the edges, condensation channels blocked with dirt, water ponding against the kerb, or a seal failing on the glass unit. Sometimes the water is coming in elsewhere and running along to the rooflight. A diagnostic visit finds the real source before anyone starts applying sealant.

Is it condensation or a leak?

Condensation tends to appear on cold mornings, on the inner face of the glass, and runs down the frame. A leak usually follows rain or wind from a particular direction and often stains the ceiling around the opening. Blocked condensation channels can make the two look alike. Photos and a note of when it happens help us narrow it down before the visit.

Should I repair or replace my old leaking rooflight?

It depends on the age and condition of the unit and what has failed. A single perished seal or a blocked channel is worth repairing. A brittle, discoloured dome, a rotten kerb, or several faults at once usually make replacement the better value. After the diagnostic visit we set out both options with prices, so you can decide with the full picture in front of you.

For a repair in St Ives, start with photos and the postcode; we confirm the visit price before anything is booked.
