What suits a cottage roof in the historic centre?
Older brick cottages commonly have slate roofs. We cannot see which roof you have from here, so we look at it at the survey. If it is slate, the question is what sits quietly in it and what the council will want to see.
Why a flush unit
A conservation rooflight lies close to the roof covering, usually with a single slim bar across the glass. From the road it reads as a feature of the roof rather than a box on top of it. Modern ones are double glazed, and some open. The page on comparing conservation rooflights shows what the choices are, and the VELUX conservation range is one of them.
Opening and cleaning
A cottage bedroom under a slope may have little floor space, with the window close to the bed. If a child sleeps there, a restrictor is worth having, though on the window the room would use for escape an adult must still be able to open it right up, and we ask which window that is. A flush unit's outside glass is wiped from a ladder or, if it tilts, from within, and we tell you which applies. On some models a blackout blind runs in rails, which suits a room where the window may stay open a crack.
What the survey looks at
The slate's condition and its fixings, where the rafters fall and whether the window can be set between them without cutting. A window sized to the rafters is a simpler job than one that needs the timber altered, and we say so plainly if a different size would make it so. The point of the survey is to find that out on the day, with the room in front of us, rather than from a photograph. If you are replacing an old window, the size code on its label is the first thing we read; see finding your size code.
A cottage bedroom, thought through
- Roof
- Slate, checked at the survey and not assumed
- Window
- Flush conservation unit, sized to the rafters
- Child's room
- A restrictor on the sash and a blackout blind on rails
- Wiping
- From within if the sash tilts, otherwise from a ladder
