Ultraframe low pitch lean-to roofs, made to your specification
A shallow lean-to can help where the wall height limits a conventional conservatory roof. We supply roof kits for your installer to assemble, with the glazing, finish, drainage and side support agreed before manufacture. Start with your approximate sizes; we will confirm the specification and exactly what your quotation includes.
Glass roofing
Choose a glass roof enquiry for a clearer view of the sky. Ask about solar control and self-cleaning options. The system guide describes 24mm units; the exact glass build-up, pane sizes and pitch need checking together.
Structural firrings
Tapered side supports bridge level side frames and the roof slope. Standard 2.5° and 5° firring options are listed, with raked side frames as an alternative. Include the door positions so we can assess support.

Pitch guidance: the Classic low pitch design guide covers 2.5°–10°. Other Ultraframe low pitch configurations specify glass from 5°. The designer flags glass below 5° for technical review rather than treating it as an approved combination.
Firrings, raked frames and restricted eaves
Firrings let a sloping roof sit above level side frames. They are structural parts of the design, so their angle, length and support must suit the roof. Raked frames instead follow the roof slope. Neither option removes the need to check the existing frames and load paths.
Match the angle
Select 2.5° or 5° firrings to match the roof. For another pitch, ask us to assess raked frames or an alternative support detail.
Check the available height
Send the underside-of-soffit height, frame height and projection. The slope rise shown in the designer excludes roof profiles, wallplate, flashing and installation clearances.
Plan the drainage
A house-side box gutter may help with a restricted soffit detail. It requires project-specific support and outlet design. Tell us about doors beneath it and any existing drainage.

Low pitch lean-to roof questions
Can I use glass at 2.5°?
Do not assume every low pitch roof or glass option is suitable at 2.5°. Ultraframe documents cover different configurations. We flag glass below 5° for technical review and confirm the exact system and glazing before quoting.
Do I need firrings?
If your side frames are level, structural firrings may provide the tapered support beneath the sloping roof. Raked frames can be an alternative. Send photographs and dimensions so the correct detail can be agreed.
Is fitting included?
No. This is a supply-only roof kit service for trade customers, builders and competent DIYers. Installation, access equipment, walls, windows, doors, foundations and other building work are not included unless expressly listed in a separate agreement.
How much does a lean-to roof kit cost?
The price depends on size, location, glazing, finish, firrings and any special drainage or support. Use the designer and enquiry form for a project-specific quotation with the supply details and delivery costs confirmed.
