Before choosing a new conservatory roof, the existing frame, supports and foundations need checking. The way you use the room and its insulation also matter. A different covering can change the loads on the building, so suitability needs to be established before you commit to a product.
We know you may want a conservatory that's easier to use throughout the year. Before choosing a new roof, the structure, glazing, insulation and ventilation all need to be considered. Here's what to discuss when planning the work and comparing quotes.
Start with the Existing Conservatory
Tell us the conservatory's age and construction if you know them. Is it separated from the house by doors? How is it heated and ventilated? Mention any leaks or movement, and send safe photos showing the whole structure.
Before choosing a roof, find out what needs checking about the frame, supports and foundations. Even a replacement described as lightweight may not suit every conservatory. The proposed load needs assessing for your building.
We can discuss the roofing options and explain what still needs confirming. The roof and the structure beneath it need to be considered together.
Check the Requirements for the New Roof
Some conservatories benefit from building-regulations exemptions subject to conditions. Altering the roof or the relationship with the house can change the assessment. Planning Portal specifically advises considering building regulations and planning when replacing a conservatory roof. [1]
An earlier exemption doesn't automatically cover a new solid roof. The conservatory's construction, use and proposed changes need checking to establish which requirements apply.
Agree who will check approvals, arrange any calculations and provide completion documents. A brochure about the roof system doesn't confirm approval for your particular project.
Compare Complete Roof Options
| Option to Discuss | What You Want to Achieve | Important Questions |
|---|---|---|
| Renewed glazed or translucent roof | Retain a high level of daylight | What glazing, shading, ventilation and structural details are proposed? |
| Insulated solid-roof system | Improve insulation and change the room's internal finish | Is the existing structure suitable, and what approvals are required? |
| A mixed design with rooflights | Balance an insulated roof with selected daylight openings | How are openings, support, weatherproofing and shading coordinated? |
| Local repair to the existing roof | Fix a local problem while keeping the existing roof | What's causing the problem, and is the rest of the roof sound? |
| Wider reconstruction | Put right problems in the wider conservatory | Who is responsible for structure, walls, floor and other trades? |

Use these options as a starting point for discussing your plans. Their suitability, and which parts of the work we can provide, need to be confirmed for your conservatory.
Check the Structure Before Choosing the Finish
The new roof needs suitable support and connections. Tell us about movement, rotten or corroded parts and any earlier alterations. These need considering alongside the weight of the proposed covering.
Ask which checks have been carried out and who is responsible for the structural assessment. A product description can't replace checking your own conservatory.
Planning Portal notes that structural changes and significant changes in covering weight can need building-control approval. That's why the actual alteration needs checking, even when it's described as a roof replacement. [2]
Insulation, Heating and the Link to the House
A new roof may improve comfort, but the walls, glazing, floor and draughts matter too. Tell us how the room feels now and how you'd like to use it so the roofing work can be considered as part of the wider plan.
Let us know whether you plan to keep the doors between the conservatory and house. Changing that connection can affect the design and approvals. Any claimed heating saving needs an assessment of your building, rather than a general promise about the roof.
Energy Saving Trust's insulation advice explains heat loss and moisture control. It provides useful background, but doesn't calculate the savings for your conservatory. [3]
Daylight and Summer Comfort
A solid roof may reduce daylight in the conservatory and the room behind it. If you're considering rooflights, plan their position, glazing and shading early so the finished space works for you.
Energy Saving Trust's summer advice covers shading and using cooler air when safe. These are useful things to consider alongside the glazing and ventilation in your proposed roof. [4]
Tell us what you'd like to improve about the room. A roof change may help, but keeping it comfortable in every season can also require changes to glazing, shading, heating or ventilation.
Leaks and Existing Roof Defects
If leaks are the reason you're considering replacement, we need to find the cause first. The fault may be at a panel, gutter, frame or the junction with the house. A local repair may be enough if the surrounding roof is sound.
We'll explain which junctions need work and what would remain in place. That helps you check that the proposed roof addresses the leak that prompted you to get in touch.
The roof leak investigation guide explains what to tell us about a leak and how those details help us investigate.
What a Conservatory-Roof Quote Should Include
Check that the quote explains removal of the old roof, any support work, the new system, insulation, rooflights, gutters and the junction with the house. It should also make clear what's included inside, along with access, waste, professional fees and VAT.
Ask what needs arranging separately, such as plastering, electrics, heating or changes to frames and doors. If you're planning a larger renovation, other trades may need to be involved and their work coordinated.
Citizens Advice recommends clear written quotes and an explanation of what could change the price. This matters when one proposal includes structural or internal work that another leaves out. [5]
Plan Completion and Keep the Records
We'll discuss access, use of the room and protection for the conservatory and adjoining house. Please leave checks at roof level and movement of materials to people with suitable equipment and training. [6]
Keep the agreed materials and work details, relevant calculations, completion records, product information and guarantees. These should describe what was fitted to your conservatory, along with how to look after it.
Before the job is signed off: check that the paperwork explains what changed, what was kept, who designed the work and which guarantee applies. Clear records help with maintenance and can be useful when you sell the property.
We can discuss suitable conservatory roof work, extension roofing and roof windows in Newcastle, Gateshead, Washington and surrounding areas. Tell us about the existing conservatory and what you'd like to change through our quote page.
Frequently Asked Questions
Can Every Conservatory Take a Solid Roof?
No. The frame, connections and supports need assessing for the proposed roof. Even a lightweight system may not suit every building. Confirm who will carry out the necessary structural checks before choosing it.
Does a Small Conservatory Automatically Avoid Building Regulations?
Not necessarily when it is altered. Exemptions have conditions, and replacing a roof or changing the relationship with the house can affect the position. Check the actual proposal rather than relying only on floor area or an earlier exemption.
Will a New Roof Make the Room Cheaper to Heat?
It may help, but the walls, floor, glazing, draughts and heating also affect energy use. Any estimate of savings needs to relate to your whole conservatory. We can discuss the roofing work and where wider changes may be needed.
Will a Solid Roof Make the House Darker?
It can change daylight in both the conservatory and rooms behind it. The effect depends on the layout and any rooflights or glazing retained. Consider daylight and summer shading at design stage, not after the roof has been chosen.
Could My Existing Roof Be Repaired Instead?
It may be possible if the fault is local and the rest of the roof is sound. We'll explain the cause and why repair or replacement would be suitable.
Are Internal Finishes Included in a Roof Quote?
Only if they're listed in the quote. Ask about ceilings, plastering, electrics, decoration and any changes to doors or heating. Compare what the finished job includes, as well as the roof price.
What Documents Should I Keep?
Keep the quote, agreed changes, drawings, relevant calculations and completion documents, plus product details, invoices, guarantees and care instructions. They can help with future maintenance or a sale.
