Roofing projects in Treharris can range from small repairs to full replacements. Roofers can investigate leaks, repair ridge tiles, renew membranes and fit new coverings. Share the roof type, pitch and any scaffolding needs so quotes are realistic. Mention any previous repairs and whether internal damage has appeared.
Start with a clear brief and request quotes from roofers. Note the property type, roof pitch and any scaffolding needs. Describe the job and get quotes to weigh timelines and costs.

ROOFING ESSENTIALS
A quick guide to planning your project, understanding costs and choosing a good Roofer.
QUALITY & GUARANTEES
An insurance-backed guarantee protects you if the roofing company goes out of business during the guarantee period — a separate product from the roofer's own workmanship guarantee. Not every roofer offers this; worth asking specifically for larger jobs like a full re-roof.
SEASONAL CONSIDERATIONS
Before winter: check for loose tiles and clear gutters, since blocked gutters and ice are a common combination for damage. After a storm: a visual check from the ground for obvious damage, before assuming everything's fine just because there's no visible leak yet.
GETTING A QUOTE
Materials (tiles, felt, leadwork, scaffolding hire) are often a smaller share of a re-roof quote than labour, particularly given the time and access involved. A cheap quote is worth checking for the same tile/material spec as competing quotes, not just a lower labour day rate.
USEFUL TO KNOW
A small tile repair is usually a few hours. A full re-roof on an average semi-detached house commonly takes 1-2 weeks including scaffolding, weather permitting — roofing work is one of the more weather-dependent trades, so timelines can shift.
SAFETY & COMPLIANCE
The National Federation of Roofing Contractors is the largest UK roofing trade body, representing over 60% of the industry. NFRC members are vetted on technical competence and financial standing, and some offer an insurance-backed guarantee on top of their own workmanship guarantee — worth asking whether this applies to your quote.
GOOD TO KNOW
A dormer window (as opposed to a flush skylight) changes the roofline itself and almost always needs both planning consideration and Building Regulations sign-off, unlike a straightforward re-roof. This is more involved than most roofing work and often overlaps with loft conversion specialists.
GOOD TO KNOW
Older roofs often used bituminous felt underneath the tiles, which can perish and needs replacing during a re-roof; modern breathable membrane lasts longer and manages moisture better. If you're having a full re-roof, this underlay is worth confirming as part of the spec, not just the visible tiles.
USEFUL TO KNOW
A proper roof survey looks beyond the visible tiles — timber condition in the loft, flashing around chimneys and valleys, ventilation, and signs of past repairs. Worth requesting one before buying a property with an older roof, since problems aren't always visible from ground level or even from inside the loft.

Many older terraces will need slate matching, lead flashing repairs and chimney work, whereas suburban properties sometimes require flat-roof repairs on extensions or replacement of modern felt systems.
NFRC or Competent Roofer membership is a helpful indicator of an installer’s standards and insurance cover, and careful planning for scaffolding or temporary access is essential on narrow streets. Contractors should also allow time for local building-control checks where necessary. Homeowners should request NFRC/Competent Roofer credentials, examples of slate or flashing repairs on similar local houses, and a detailed access and waste management plan that fits the restricted spaces often found in CF46.
