VELUX Window Installers › Penarth › Guide
Choosing a roof window is mostly a question of what the room needs. How much light, how high the sill should sit, where the rafters run and what the roof is covered with all feed into the decision. In Penarth, the shape of the roof space and the view towards the sea add their own considerations.
Start with the room beneath
Think about how the room will be used. A bedroom needs enough light and an opening that is easy to reach, while a study wants steady light without glare. Standing in the loft, mark where you want daylight. We then compare that with what the roof structure and pitch will allow before suggesting a size. Tall Penarth roof spaces often give more freedom than low loft spaces, but the lower slope still limits where a window can sit.
Sill height and the view
A window set too high gives light but no view, and one set too low can make a room feel cramped or awkward to use. In Penarth many people want a glimpse of the sea or rooftops, and the pitch of the slope decides how that works. We check the sight line from where you will sit or stand, and we think about how the window will be reached for opening and cleaning.
- Sill height set for sitting and standing views
- Pitch affects how much sky you see
- Position checked against furniture and floor space
Rafters and the structure
Roof windows are made in sizes that often suit standard rafter spacing, but not always. If an opening lands across a rafter, the timbers around it may need trimming and doubling-up. This is checked on site. Moving the window a little, or picking another size, can sometimes avoid extra structural work, and it keeps the job simpler for you.
Roof covering and appearance
The roof covering decides which flashing kit is needed, and that affects what sizes and groupings are practical. Slate, plain tile and concrete tile all take different kits. From the street, windows look tidiest when they line up with each other and sit in line with the slope, which matters in Penarth's conservation-area feel.
- Flashing kit chosen for slate or tile
- Windows aligned for a tidy roof elevation
- Groupings checked against the covering
Planning, then a proper look
A new window may need planning or Building Regulations checks — we advise before work starts. Once we have seen the loft and the roof, we can give you a straight view on the best size and position. Do not climb onto the roof to measure; call us for a proper look and we will do it safely.

Common Questions
Is a bigger roof window always better?
Not always. Larger windows give more light but need more structure around them, and may be harder to fit between rafters. The right size balances light, headroom, the roof covering and the structure, and we help work that out.
Can I put two roof windows side by side?
Often, yes. Windows can be grouped, sharing flashing details where the kit allows it. The covering, rafter spacing and appearance from the street all matter, so we check these on site before agreeing a layout.
Should roof windows face the sea?
It depends on the room and the aspect. Windows facing the sea give a view, while those on other slopes may give steadier light. We talk through which slope suits how you use the room, and the exposure of each.
