Lead Cladding for Dormer Windows – A Recent Moose Roofing Project on the Isle of Wight
Share:
At Moose Roofing & Building, we take pride in delivering high-quality roofing and cladding work, no matter the challenge.
Our recent project on the Isle of Wight saw us working with a national house-building firm to clad eight dormer windows in Code 5 lead, across a development of four new dwellings.
The Project: Dormer Lead Cladding in Niton & Whitwell
ο»ΏThe site, located on land off Allotment Road and Chatfield Road, is part of a new residential development connecting the picturesque villages of Niton and Whitwell. Each of the four new homes featured two dormer windows, all of which required expert lead cladding to ensure they were both weatherproof and aesthetically in keeping with the development’s traditional style.
However, the job didn’t come without its challenges. By the time we arrived, the carpenters had already fitted the soffits—something that ideally happens after the leadwork is completed. But at Moose Roofing, we’re no strangers to adapting on-site, and our team made sure the job was done to the highest standard despite the extra complexity.
What Goes into Cladding a Dormer with Code 5 Lead?
ο»ΏCladding a dormer in Code 5 lead isn’t just about appearance—it’s a crucial step in ensuring long-term protection from the elements. Lead is one of the best materials for weatherproofing, as it expands and contracts naturally with temperature changes, making it highly durable.
Here’s a breakdown of what the process typically involves:
1. Preparation & Underlay
Before the lead is applied, the dormer’s timber structure needs to be covered with a suitable underlay, such as a geotextile membrane. This prevents condensation and helps the leadwork last for decades without corrosion.
2. Measuring & Cutting the Lead Sheets
Each section of lead needs to be carefully measured and cut to fit the specific dimensions of the dormer. For this project, we used Code 5 lead, which is thicker than standard Code 4 and provides superior strength—ideal for dormers exposed to wind and rain on the Isle of Wight.
3. Fixing & Dressing the Lead
Once the sheets are in place, they are secured using lead clips and fixings, ensuring they allow for natural movement while staying watertight. The edges are then neatly dressed down, ensuring a smooth, professional finish that blends seamlessly with the rest of the roof.
4. Patination Oil Application
The final step is applying patination oil, which helps prevent staining and ensures the leadwork weathers evenly over time. This step is often overlooked, but it makes a huge difference in maintaining the lead’s smart, uniform appearance.
Another Quality Finish from Moose Roofing
Despite the unexpected challenge with the pre-installed soffits, our team completed the job on time and to our usual high standards. The finished dormers not only look fantastic but will also stand up to the coastal weather for many years to come.
We love working on leadwork projects, whether it's new builds like this or heritage properties needing traditional lead roofing repairs. If you're looking for experienced, professional roofers in Henley-on-Thames, Oxfordshire, the Isle of Wight, or beyond, Moose Roofing & Building has you covered.
