Professional Building Contractor Services in Roscommon
That’s the role Alltask Roofing & Building plays for our clients. Instead of handing a project off between separate tradespeople and hoping the handovers go smoothly, we run each job as a single, managed process. One team oversees materials, scheduling and inspections, so problems get caught early rather than discovered at the worst possible moment.
Key Deliverables
- Quality control and compliance management
- Architectural execution and finishing
- Structural construction and civil works
- Interior and exterior construction works
- Final inspection and project handover
Scope of Services
Our building services in Roscommon span the entire construction process, not just individual trades. That starts with new house construction for self-build and turnkey clients alike, and extends into home extensions designed to add usable space to an existing property.
Property renovations, from single rooms to full refurbishments, make up a steady share of our work, alongside structural alterations such as load-bearing wall changes carried out under proper engineering oversight.
Roofing has always been part of our foundation as a company, so it’s built into our building projects rather than bolted on separately. Groundworks, blockwork, boundary walls and interior finishing round out the service, giving clients one contractor to manage the whole job instead of several.
Our Approach
We start every job with a proper conversation, not a rushed estimate. That means an initial consultation to understand what you actually want from the finished project, followed by a site visit to assess what we're working with.
Quality & Safety
We don't treat Building Regulations compliance as a box-ticking exercise it's built into how we plan and execute every job, whether that's a small domestic extension or a larger commercial project. Site safety follows the same principle, with current Health & Safety practices applied consistently to protect our crew, our clients and anyone else near the site.
Our Building Contractor Services in Roscommon
New House Construction
We support new house construction from the earliest planning conversations through to the day you get the keys. Some clients want hands-on self-build support, managing parts of the project themselves with our guidance; others prefer a fully turnkey approach where we handle everything.
Either way, we liaise directly with architects, engineers and the local planning authority to keep the process moving. Whether the design is a bespoke one-off or a more standard layout, our team handles the sequencing groundworks, structure, first fix, second fix, finishes so nothing stalls waiting on the wrong trade at the wrong time.
Roscommon’s mix of rural and town sites means access and ground conditions vary a lot from job to job, and getting that assessment right at the outset avoids delays once construction is underway.
House Extensions
Extending rather than moving is a common choice for growing families across Roscommon, and we build rear, side and double-storey extensions to suit whatever the existing property allows. Kitchen extensions are a particular specialism, usually involving a mix of structural work, new services and finishing that needs to tie into the rest of the house.
We design and build every extension to match the existing structure both physically and visually, so it reads as part of the house rather than an obvious addition, and always within current Building Regulations requirements.
Property Renovations
From full refurbishments to more focused modernisation projects, our renovation work covers a wide range of scope. Many of the older properties we work on, particularly around Roscommon Town and Elphin, need a careful balance between preserving character and bringing the building up to a modern standard.
We handle everything from updated layouts and finishes through to more involved upgrades like rewiring coordination, improved insulation and window replacement. A renovation gets the same level of planning and attention as a new build, just applied to an existing structure.
Structural Alterations
Commercial Construction
We also work with businesses across Roscommon on commercial construction and fit-out projects, covering offices, retail units and hospitality spaces such as cafés and guesthouses. Commercial renovations are part of this too, often carried out with a focus on minimising downtime for businesses that need to keep trading.
As commercial builders Roscommon businesses turn to for these projects, we understand that disruption has a real cost, and we plan accordingly.
Groundworks & Foundations
Every build starts underground, and we handle site preparation, excavation, drainage and foundation work as a matter of course. This includes assessing the specific ground conditions of each site before committing to a foundation design.
Roscommon’s terrain varies considerably, from lower-lying land around Strokestown and Tulsk to firmer ground elsewhere in the county, and we factor this into planning before any digging starts.
Blockwork & Masonry
Structural walls, boundary walls, brickwork, stonework, and retaining walls all fall under our blockwork and masonry services. This is foundational work in the most literal sense; it supports everything built above it, so we hold it to a high standard on every job, residential or commercial.
Roofing & External Building Works
Roofing is where Alltask Roofing & Building started, so it’s naturally woven into our building projects rather than treated as a separate add-on. That covers new roof installation, flat roofing, chimney repairs, fascia and soffits, and gutter repairs, along with external finishing like exterior painting and power washing.
Keeping roofing and external works in-house means one less handover between trades, and a more consistent finish from the ground up to the ridge.

Building Contractor Costs in Roscommon
There’s no single figure that applies to every building project, because cost depends on so many variables project size, labour needs, material choice, site access, ground conditions and the finishing specification you choose.
Given how much these factors vary, we don’t quote off generic price lists. The table below gives a general sense of scope and what drives cost on each project type, but your own quotation will be based on your specific site and brief.
Access is one of the more overlooked cost factors. A site with tight access for machinery or deliveries typically takes longer and costs more than an equivalent job on an open plot, purely because of the extra time involved. Ground conditions can add cost too rock, poor drainage or unstable subsoil discovered during excavation aren’t always predictable until the digger is on site.
| Project Type | Typical Scope | Key Cost Factors |
|---|---|---|
| Home Extension | Rear, side, double-storey, or kitchen extension | Extension size; foundation and structural work; finishing specification |
| Property Renovation | Full refurbishment or targeted modernisation | Extent of works; age and condition of property; interior finishes |
| Structural Alteration | Knock-through walls, RSJ installation, load-bearing changes | Engineering design requirement; number of walls affected; making good works |
| New House Construction | Self-build support or fully turnkey new build | House size and design; site conditions; specification level; groundworks |
| Commercial Construction | Office, retail, or hospitality fit-out and renovation | Floor area; trading disruption requirements; fit-out specification |
| Groundworks & Foundations | Site preparation, excavation, drainage, foundations | Ground conditions; site access; drainage requirements |
