Is It Time for a New Roof?

Not every roof issue requires full replacement. Here are signals that a new roof may be the right option:
Recurring leaks in multiple areas of the roof
Widespread slipped, broken, or missing tiles/slates
Sagging roofline or failing roof structure
Underlay visible or deteriorated beyond repair
Patch repairs no longer holding effectively
Major storm damage affecting large sections
Roof at end of expected life (40+ years for slate, 30+ for tiles)
Planning extension or loft conversion requiring roof work
Significant internal damp and water damage
Roof failing building survey or structural assessment

We’ll inspect your roof and explain honestly whether repairs are enough or if replacement is the better option.

We help you choose the right roofing material based on your property type, budget, and long-term expectations. Slate roofing offers a traditional appearance and excellent longevity — particularly suited to period properties and conservation areas. Tile roofing provides a cost-effective, durable option with a wide range of colours and profiles to match existing rooflines. Both materials have proven performance in Dublin’s weather conditions. We’ll explain the pros and cons of each option during the survey and recommend what’s best for your project. All materials are sourced from reputable suppliers and installed to manufacturer specifications.

Frequently Asked Questions

How long does a new roof installation take?
Typical timelines vary depending on roof size, complexity, material choice, and weather conditions. A standard domestic re-roof on a semi-detached or terraced house in Dublin usually takes 3–7 working days once started. Larger properties, complex rooflines, or additional work like chimney repairs or leadwork can extend this. We provide an estimated timeline during the quote stage and keep you informed of progress throughout. Weather plays a role — if heavy rain is forecast, we may pause work to protect the interior and ensure quality. We aim to complete the work as efficiently as possible while maintaining high standards and minimising disruption to your household or business.
This depends on the extent and location of the damage, the age of the roof, and the condition of the underlying structure. If the issues are localised — a few slipped tiles, a small leak, or storm damage in one area — repairs are often sufficient. However, if you’re experiencing recurring leaks in multiple areas, widespread tile damage, visible sagging, or the roof is at the end of its expected life, replacement may be the more cost-effective long-term solution. We’ll inspect your roof honestly and explain both options. Our goal is to recommend what’s right for your property and budget, not to oversell. If repairs will do the job properly, we’ll say so. See our roof repairs page for more on repair services.
In most cases, yes. We work with suppliers who stock a wide range of slates and tiles in various colours, profiles, and finishes. For common tile types used across Dublin, matching is straightforward. For older properties with natural slate or discontinued tile patterns, matching can be more challenging but is often possible through reclaimed materials or close alternatives. We’ll inspect your existing roof during the survey and advise on the best match. If an exact match isn’t available, we’ll explain the alternatives and show samples where possible. For conservation areas or listed buildings, we’re experienced in sourcing appropriate materials that meet planning requirements.
Several factors influence the cost of a new roof installation. Roof size and pitch are the primary drivers — larger roofs and steeper pitches require more materials and labour. Material choice is another key factor: natural slate is typically more expensive than concrete tiles, for example. The complexity of the roof also matters — dormer windows, valleys, hips, and multiple chimneys add time and cost. Access to the property, scaffolding requirements, and waste disposal also play a role. Additional work like chimney repairs, leadwork renewal, or structural repairs will increase the overall price. We provide a clear written quote that breaks down these costs so you understand what you’re paying for. No hidden extras, no surprises.
Yes, always. After surveying your roof and discussing your requirements, we provide a detailed written quote that outlines the full scope of work, materials to be used, timeline estimates, and cost breakdown. The quote includes everything discussed — roofing material, underlay, battens, ridge/verge finish, flashings, waste removal, and any upgrades or additional work agreed. We explain the quote clearly so you understand what’s included and why. If you have questions or want to adjust the specification, we’re happy to discuss and revise the quote. Once you’re satisfied and approve the quote, that’s the price you pay — no surprises, no hidden costs added later.
Yes, we carry full public liability insurance for all roofing work, including new roof installations and re-roofing projects. This protects your property and covers our team while working at height. New roof installations involve scaffolding, material handling, waste removal, and working on exposed roof structures — all of which we approach with proper health and safety procedures. You can ask to see our insurance documentation at any time. We take safety and professionalism seriously on every project, whether it’s a small domestic re-roof or a larger commercial installation. Your property is fully protected while we work.

Yes, we install both dry ridge and dry verge systems as part of new roof installations or as upgrades during re-roofing projects. Dry ridge systems use mechanical fixings rather than mortar, providing long-term ridge security without the cracking and maintenance issues associated with traditional mortar bedding. Dry verge systems offer a neat, durable finish for gable ends and help prevent wind uplift and water ingress at roof edges. Both systems are increasingly popular for new roofs and re-roofs in Dublin due to their reliability and low maintenance. We’ll explain the benefits and costs during the quote stage. See our pages on dry ridge installation and dry verge installation for more details.

Yes, we carry out new roof installations on both domestic and commercial properties across Dublin. Our domestic work includes houses, semi-detached and terraced properties, bungalows, and residential extensions. For commercial clients, we work on offices, retail units, industrial buildings, schools, and other commercial structures. The process is similar — survey, fixed quote, professional installation — but commercial projects may involve additional considerations like working around business hours, higher safety requirements, or phased work to minimise disruption. We’re experienced in managing both types of projects and provide the same attention to quality and detail regardless of property type. Contact us to discuss your specific requirements.
