Installed by Experienced Roofers
Installing a roof window isn’t simply a case of fitting a window.
The window needs to become part of the roofing system around it.
Incorrect flashing, poor slate or tile detailing and badly installed underlay can result in leaks and expensive damage later.
That’s why choosing an experienced roofing contractor matters.
DMG Services Group has extensive experience working with slate roofs, tiled roofs and flat roofing systems, allowing our team to ensure your new roof window is properly integrated into the existing roof.
From removing the existing roof covering to installing the window, flashings and surrounding slates or tiles, we can manage the complete installation.
We can supply and install a wide range of roof-window solutions, including:

Send us photographs of your existing roof/window and we’ll help you establish the best option.
Is Your Existing VELUX Window Getting Old?
Older roof windows can eventually become difficult to operate, draughty or start allowing water into the property.
Common problems include:
Water leaking around the window
Condensation
Draughts
Damaged or deteriorated flashings
Rotten timber
Failed glazing
Windows that no longer open or close properly
Cracked or damaged roof tiles around the window
Slipped or broken slates
Poor previous installation
DMG can inspect your existing roof window and determine whether a repair is practical or whether replacing the window would provide a better long-term solution.
Where replacement is required, we’ll remove the old window, install the new roof window and reinstate the surrounding roofing materials correctly.
VELUX Windows for Loft Conversions & Renovations
Adding roof windows can completely transform a dark loft or upstairs room.
Natural daylight can make the space feel significantly larger while opening roof windows can also improve ventilation.
Roof windows are particularly popular for:
Loft conversions
Bedrooms
Home offices
Attic rooms
Extensions
Bathrooms
Kitchens
Stairwells
Garages and workshops
If you’re unsure about the best window configuration, speak to DMG and we can discuss the options available for your property.
Roof windows don't always need to be manually operated.
Roof windows don’t always need to be manually operated.
Electric and solar-powered options can be ideal for windows installed higher up the roof or in areas where reaching the window would be difficult.
Depending on the selected system, remote operation can make opening and closing your roof windows significantly easier.
Speak to our team about the options available for your project.
One Contractor for the Complete Job
One of the biggest advantages of using DMG Services Group is that we’re not limited to roofing.
We have expanded our team to provide a range of specialist trades.
Your roof-window project may require alterations or finishing work involving:
Roofing & Slating
Joinery
Plastering
Painting & Decorating
Instead of trying to coordinate several different contractors, DMG can manage the work for you.










A leaking roof window doesn't automatically mean the window itself has failed.
Water can enter because of problems with the surrounding roof covering, flashing system or previous installation.
Our roofing team can investigate the source of the problem and advise on the appropriate repair.
If your VELUX or roof window is leaking, don’t wait until the surrounding timber, plaster or decoration becomes damaged.
Excellent, professional service.
