Rooflight leak repairs in Sandown

Tell us what you are seeing: drips, stains on the ceiling, misting, a draught, or a rooflight that no longer closes tight. Photos help. From that we arrange a diagnostic visit in Sandown, with its cost agreed before booking. On site we check the sealant, the flashing or membrane upturn, the condensation channels and the glass. Then you get a straight answer and, if a repair is worth doing, a written quote for the rooflight leak repairs.

Areas around Sandown we cover

Distance is rarely the deciding factor. A roof in Ryde, 5 miles from Sandown, gets the same survey, the same written quote and the same fitting process as one in PO36, PO37 and PO35. What changes the price is the job itself: size of unit, roof type, access and lifting. Newport, around 7 miles out, is treated the same way.

What the job includes

  • Rotten kerb sections replaced where the timber has gone soft
  • Lifted flashing or tape removed and renewed
  • Controlled water test where it helps pin down the entry point
  • Leak or condensation — We work out whether the water is coming from outside or forming inside on cold glass.
  • Age of the rooflight — We weigh the age and condition of the unit before recommending a repair.

How a repair visit goes

A repair visit starts outside. The fitter looks at the roof around the unit for ponding, split membrane, loose flashing and failed sealant, then moves inside to check stains, the frame and the condensation channels. Where it helps, a controlled water test narrows down the entry point. Before leaving, they explain what they found and whether a small fix can be done within the agreed visit, or needs a separate written quote.

Planning, building control and Sandown

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 Sandown

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.

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.

Can you replace just the misted glass?

Often, yes. Misting between the panes means the sealed unit has failed, but the frame around it may be perfectly sound. Where the maker's design allows the glass to be changed, we measure the unit and fit a replacement, which costs less than a whole new rooflight. Where it does not, or the frame is also worn out, we explain why replacement is the better option.
