Skylight replacement in Lowestoft: what is involved?
Thinking about skylight replacement in Lowestoft? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Typical uses for skylight replacement include older extensions due a modern rooflight.
Lowestoft sits about 15 km from Great Yarmouth and 35 km from Norwich, and we cover the whole NR32 postcode district and the roads in between.

Planning and building rules for Lowestoft
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight replacement in Lowestoft: questions
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Do I need to be at home for the survey in Lowestoft?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Lowestoft?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
