Who it's for
When to Choose Roof Installation
Roof installation is the right fit when your building needs a full roof system built - for example, an existing roof has aged to the point that a new layer system is needed from membrane to covering, or an extension, loft conversion, or roof-shape change has created the need for an entirely new system. This differs both from new-build roof construction, which is about building an entirely new load-bearing structure - the rafters - for a new building, and from covering replacement, which only touches the outer layer on top of an existing, technically sound structure.
In practice, most of our clients here are homeowners carrying out a significant renovation who want the roof system built correctly through every layer - not just a new covering laid over an aged or incomplete structure underneath. This service is also common after a loft conversion, when the previous roof system - designed for an unheated attic - no longer meets the thermal and ventilation requirements of a living space.
Before starting any work, we always carry out an objective structural assessment - if the rafters and load-bearing elements are sound, we install on top of them; if we find damage, we tell you honestly and offer a solution without pushing a more expensive service that isn't objectively needed.
The problem we solve
An Incorrect Roof System Shortens the Whole Roof's Lifespan
Most premature roof problems don't come from the covering itself, but from incorrectly built layers underneath it.
Insufficient Ventilation
Without a proper ventilation gap, condensation forms and damages the timber structure and insulation from the inside.
Incorrect Membrane
An unsuitable or badly installed breather membrane doesn't do its job - moisture gets into the structure instead of evaporating out.
Weak Detail Solutions
Ridges, eaves, and details are the most common problem points - they can't be patched superficially, they need to be built correctly the first time.
Scope of work
What's Included in Roof Installation
Breather Membrane & Vapor Control
Installing the waterproofing membrane over the rafters with correct overlaps and sealed joints; a vapor barrier on the inside where insulation is planned.
Battens & Counter-Battens
Counter-batten strips to create the ventilation gap, then battens spaced to the covering manufacturer's requirements.
Ventilation System
Eaves intake and ridge outlet ventilation, so airflow beneath the covering stays continuous along the entire roof.
Covering Installation
Installing or fixing your chosen covering material to the manufacturer's specification - metal, tile, standing-seam, slate, or shingles.
Details, Windows & Gutters
Ridge, eaves, and verge flashing details, roof window and chimney flashing, and the rainwater drainage system.
System layers
The Roof Structure, Inside to Outside
Each layer has its own function - skip one or install it incorrectly, and the whole system suffers.
| Layer | Function |
|---|---|
| Load-bearing structure (rafters) | Carries the roof and load weight, defines the roof's shape and pitch |
| Vapor barrier (if insulated) | Prevents indoor moisture from reaching the insulation from inside |
| Insulation (if included) | Reduces heat loss through the roof plane |
| Breather membrane | Protects the structure from outside moisture while letting vapor escape |
| Counter-battens | Creates the ventilation gap between membrane and covering |
| Battens | The load-bearing base for fixing the covering material |
| Covering | The visible, weather-resistant outer layer |
If the building already has an insulated loft space, we coordinate the insulation and vapor-barrier solution with the existing situation - the full insulation system is described in detail on our roof insulation page. Regardless of covering material, the ventilation gap between counter-battens and battens is a technical necessity, not an optional extra - it's the only way to remove moisture that gets into or forms within the structure before it damages the timber or insulation.
Materials
Choosing a Covering Material
The core installation principles are similar for every covering, but each material has its own technical requirements.
Critical details
The Details That Determine a Roof's Durability
Most of the roof problems we've encountered over the years didn't originate in the middle of the covering, but at detail points - where the plane changes or different elements meet.
- Ridge detail - provides ventilation outflow and continuous waterproofing at the roof's highest point.
- Eaves detail - ventilation intake, gutter bracket fixing, and correct membrane run-off.
- Verges - edge finishing that protects the battens and membrane from wind load.
- Chimney and roof window flashing - the points where continuous membrane and covering coverage are technically hardest to achieve.

Quality control
How We Check Completed Work
At the end of each stage - before installing the next layer - we check the previous layer's execution: membrane overlap and joint sealing, batten spacing, fastener count, and detail execution. We photograph every stage so the process stays verifiable even after the work is done.
Price & duration
What Affects Cost and Timeline
The cost of roof installation is affected by the roof's area and shape, pitch angle, chosen covering material, the condition of the existing structure, and the number of details (windows, chimneys, flues). For an average single-family home, work usually takes 5-12 working days. For exact price factors and typical ranges, see our pricing page - here we only outline general factors, since every site's quote is individual.
A more complex roof shape with multiple ridges and valley angles, along with a higher number of chimneys or roof windows, adds more time for detail work than the covering area itself - something we account for when planning the schedule and quote.
Warranty
A Written Warranty on Completed Work
We provide a written warranty for the installation work, while material warranties are set by each material's manufacturer. See full terms on our warranty page.
Completed project
An Example From Our Work
On a recent project in the Ķekava municipality, we carried out a full roof system installation for a gable roof following a loft conversion - structural reinforcement, breather membrane, ventilation gap, and a metal covering with full ridge and eaves detailing. The work was completed within two weeks, including roof window and chimney flashing installation. See more completed projects and photos on our projects page.
FAQ
Frequently Asked Questions About Roof Installation
New-build roof construction means building an entirely new load-bearing structure - the rafter system - for a new building or extension from scratch. Roof installation is a broader service covering the whole system - structural inspection or reinforcement, membrane, battens, ventilation, and covering - and is often used when an existing building needs a full roof system built or rebuilt.
Yes - if the assessment finds that the existing rafters and load-bearing structure are technically sound and strong enough, we install on top of them, adding or renewing the membrane, battens, and covering. If the structure is a weak point, we'll recommend a full replacement instead - something we assess objectively during the site visit.
For an average single-family home (120-200 m² of roof area), a full installation usually takes 5-12 working days depending on roof shape, pitch, covering material, and weather. We give an exact timeline in the quote after the site assessment.
We provide a written warranty for the installation work itself, while the materials carry the manufacturer's warranty. Exact terms and conditions are described on our warranty page.
Yes - roof window and chimney flashing installation is a natural part of the full installation process. We complete these details alongside the rest of the system so the waterproofing stays continuous.
