What Skylight Installation Involves
Fitting a skylight means cutting into the existing roof structure to create an opening, then fitting and sealing the unit so it performs as a permanent part of the roof rather than a potential weak point. We handle that process from start to finish, including the structural opening, flashing around the unit and making good the surrounding tiles or felt so the finished roof stays fully weatherproof. Skylights are fitted into pitched and flat roofs alike, bringing natural light and ventilation into lofts, landings, bathrooms and kitchens where a standard window isn't an option. The result is a brighter, better ventilated room without compromising how the roof performs against rain and wind.

Avoiding Leaks Around A New Skylight
The most common worry with a skylight is that cutting into the roof creates a future leak point, and that risk comes down almost entirely to how the flashing and sealing around the unit is fitted. We fit skylights with the same attention to detail as any other roof penetration, making sure the flashing overlaps correctly with the surrounding tiles or membrane rather than relying on sealant alone to do the job. That's the difference between a skylight that performs for years and one that needs revisiting within a single winter. If you already have a skylight that's leaking from a previous installation, we can also assess and correct the flashing without needing to replace the whole unit.


Improving Light, Ventilation And Energy Efficiency
A well positioned skylight changes how a room feels, bringing in natural light that a standard window often can't reach, particularly in loft conversions or rooms with limited wall space. Many skylights also include ventilation options, which helps with airflow in bathrooms or kitchens where moisture and condensation are a regular issue. Beyond the immediate light and air improvements, a properly fitted skylight contributes to a room's overall energy efficiency, reducing the need for artificial lighting during the day and helping manage temperature when the right glazing specification is used. We'll talk through the options available for your specific room before recommending which type of skylight suits the space.
Skylight Fitting You Can Trust
Roofing work across Chelmsford has kept Mark 1 Roofing Service busy for over 19 years, and every skylight installation is guaranteed for a minimum of five years. As a family run, fully insured business, we treat a skylight as a roofing job first and a glazing job second, which is the right way round given the roof has to keep performing once the skylight is in. We cover both residential and commercial properties and offer a free, no obligation quote so you know the full cost, including any making good required around the opening, before work begins.
