Roof Replacement Swindon

Full Roof Replacement in Swindon

When repairs are no longer cost-effective — when nail sickness is widespread, felt has perished, or battens have rotted — a full roof replacement is the right investment. We strip your roof back to the rafters, inspect and repair the timber structure, and build it back with modern materials designed to last 50+ years.

Swindon's post-war housing boom created tens of thousands of properties across Penhill, Park North, Park South, Pinehurst, Walcot, Eldene, Liden and Covingham — most roofed with concrete interlocking tiles on plain steel nails. These roofs are now 40–60 years old, and many have reached the end of their design life simultaneously. We're re-roofing dozens of these properties every year.

The Re-Roofing Process for Swindon Properties

We start with a free roof survey and written specification. We strip the existing tiles, felt and battens. We inspect every rafter and purlin, splicing or sistering any weakened timbers. We lay breathable roofing membrane, new treated battens, and your chosen tile — all fixed with stainless steel nails to prevent the nail sickness that's killing the original roofs.

How Long a New Swindon Roof Will Last

Modern concrete tiles (Marley Ludlow Plus, Redland 49) have a 60+ year design life. Clay tiles last 80–100 years. Natural slate can exceed 150 years. With stainless steel fixings and breathable membrane, a roof fitted today should outlast the original by decades — and never suffer the nail sickness problem that plagues Swindon's current stock.

Survey and Specification for Swindon Properties

Every re-roof starts with a full survey — not a quick look from the ladder. We check rafter condition, sarking board or decking state, ventilation adequacy, and whether the existing timber can carry the new tile weight. Swindon's 1960s properties often used lightweight truss rafters that are adequate for concrete tiles but need checking before any change to heavier materials like clay or slate.

What Happens During a Swindon Re-Roof — Day by Day

Day one: scaffold erected, old tiles stripped, felt and battens removed, all rafters and purlins inspected. Any softwood with more than 10% moisture content or visible rot is spliced or sistered with new treated timber. Day two: breathable roofing membrane laid, new treated battens fixed at correct gauge for your chosen tile, valley and hip soakers installed. Days three to four: tiles laid from eaves to ridge, cut tiles at verges and abutments, lead flashings dressed at chimneys and walls. Day five: ridge and hip tiles bedded and mechanically fixed, final checks, scaffold down, site cleared. Your home is watertight every night — we never leave an exposed roof overnight.

Tile Choice for Swindon Properties

For like-for-like replacement on Swindon's post-war estates, Marley Ludlow Plus is the workhorse — a proven concrete interlocking tile with a 60-year design life and a profile that matches what's already there. Redland 49 is an equivalent alternative. For upgrades, Marley Edgemere offers a slimmer, more modern profile. For period properties in Old Town and the Railway Village, we recommend Cupa or SSQ natural slate — sourced from Spanish quarries with a near-identical colour to Welsh slate at a lower cost. Handmade clay tiles from Keymer or Dreadnought are specified for conservation area properties where clay is the required material.

Ventilation and Insulation During a Re-Roof

A re-roof is the ideal time to upgrade loft insulation and improve ventilation — the roof is already stripped, so the cost of adding insulation is minimal compared to doing it as a separate project. We install tile vents at eaves and ridge to create continuous airflow that prevents condensation. If you're converting to a warm roof specification, we fit rigid insulation boards above the rafters before laying the membrane. Current Building Regulations require a minimum U-value of 0.16 W/m²K for roof replacements in Swindon — we meet or exceed this on every job.

Planning Permission and Building Control in Swindon

Most like-for-like re-roofs in Swindon don't require planning permission — they fall under permitted development. However, if you're changing the roof material (e.g., concrete to slate), altering the roof line, or your property is in a conservation area, you may need approval from Swindon Borough Council. We advise on this during the survey and can handle the application process if needed. Building Control notification is required for all re-roofs under Building Regulations Part L (energy efficiency) — we manage this as part of our service and ensure sign-off on completion.

Choosing Between Like-for-Like and Upgrade

Most Swindon homeowners replacing a post-war concrete tile roof have a choice: replace with the same concrete interlocking tile or upgrade to a different material. Like-for-like concrete replacement is the most cost-effective option and maintains the existing streetscape appearance. Upgrading to natural slate adds 40 to 60 percent to the cost but doubles the expected lifespan and significantly increases property value. Clay tiles offer a middle ground — better appearance than concrete, longer lifespan, but at lower cost than slate. We bring tile samples to the survey so you can see materials against your property before deciding. There is no wrong answer — each option has its own balance of cost, appearance and longevity.

Technical Specification

Our re-roofing specification exceeds Building Regulations minimum requirements. We use Tyvek Supro or equivalent breathable roofing membrane rather than traditional non-breathable felt — this eliminates the condensation problems that plague older roof constructions. All battens are treated softwood at the correct gauge for the specified tile. Every tile is mechanically fixed with A2 stainless steel nails — on exposed sites we add tile clips for enhanced wind resistance. Ridge tiles are bedded in a flexible mortar mix and mechanically fixed with stainless ridge screws. Valleys are lined in code 4 milled lead with 75mm side laps and welted central drip. We install tile vents at eaves and ridge for continuous ventilation.
