At C&M Roofing Services Ltd, we install and service genuine Velux roof windows for homeowners in Northwich and surrounding parts of mid-Cheshire. As Velux-certified installers, we fit roof windows in line with Velux manufacturer installation standards and current UK building regulations. Every Velux window we supply is backed by the Velux 10-year product guarantee.
Installing a Velux roof window is one of the most effective ways to transform a loft or upper room by introducing natural light and improving airflow. Our team regularly installs and replaces Velux windows for homes across Northwich, including areas such as Hartford, Winnington, Weaverham, Leftwich and Rudheath. Before installation begins, we assess the roof carefully, checking the roof pitch, rafter spacing and roof covering to ensure the correct Velux system is used. Matching the right flashing kit to the existing roof tiles or slate helps ensure the window integrates properly with the roof and remains fully weatherproof. All Velux work we carry out follows manufacturer guidance and UK building standards, helping ensure the window performs reliably and the roof remains protected.
Our team installs Velux roof windows using manufacturer-approved methods to ensure proper fitting and warranty protection.
We are proud members of the Association of Master Roofers, reflecting our commitment to high professional standards.






We install Velux roof windows for loft conversions, attic bedrooms and home extensions. Each window is fitted with the appropriate Velux flashing system to ensure proper weather protection and long-term reliability.
If your Velux window develops a leak, the glazing becomes misted or the opening mechanism stops working correctly, we can inspect the issue and recommend the most suitable repair and replacement with a modern Velux unit.
We also install official Velux accessories including blinds, electric opening systems and rain sensors, helping improve light control, ventilation and overall everyday usability for your home.
Velux roof windows allow natural daylight to enter from above, helping brighten loft rooms and upper living spaces.
Opening roof windows allows warm air to escape at roof level, helping regulate temperature and reduce condensation.

In many cases the window can be installed between existing rafters without major alterations. During our survey we check the roof layout carefully to determine the safest and most practical installation method.
Velux windows are designed to work with a wide range of roof pitches. When we visit your property, we measure the roof angle and recommend the correct Velux model and flashing kit to suit the roof covering.
Velux windows are generally low maintenance, but it is a good idea to keep the flashing area clear of debris and occasionally clean the window frame and drainage channels to ensure proper performance.
Yes, in some cases two or more Velux windows can be installed side by side or vertically to bring more daylight into larger loft spaces. We assess the roof structure to ensure there is sufficient space between rafters.
When installed correctly, the window is integrated into the roof with proper insulation and flashing. This helps maintain the roof’s thermal performance while still allowing natural light into the space.
