The Roof Replacement Process, Step by Step

What Does a Full Roof Replacement Actually Involve?

A roof replacement is one of the most significant jobs a homeowner can have done, and most people have little idea what to expect once our van pulls up outside. The process runs in a clear sequence, and understanding each stage helps you plan, ask the right questions, and avoid surprises on your invoice.

In Bury St Edmunds and the surrounding villages, we work on a wide range of properties, from older terraces to newer estates and farmhouses in the surrounding countryside. The materials and approach vary by property, but the core replacement process follows the same logical order every time.

Stage 1: Survey, Specification and Quote

Before a single tile comes off, we carry out a proper roof survey - on the roof itself, not just from the ground with binoculars. We check the condition of the existing roof covering, the battens, the felt underlay, the fascias, the ridge and any lead work around chimneys or valleys. This survey shapes the full specification for the job.

Driving rain works its way under worn or cracked tiles faster than many homeowners expect. A thorough survey catches secondary damage - rotted battens, sagging felt - that a cursory look would miss entirely.

The written quote you receive should list materials by type and quantity, not just a lump sum. If you're comparing quotes, check whether they include new breathable membrane, counter-battens, ridge ventilation and disposal of the old materials. Our roof replacement service covers all of this as standard.

Stage 2: Scaffolding and Stripping the Old Roof

Scaffolding goes up before any roofing work begins - there is no safe alternative on a two-storey property. On a standard semi, a full scaffold usually takes around half a day to put up and stays in place for the duration of the job.

Stripping starts at the ridge and works downward. Old tiles are carefully lowered - not thrown - into a skip or sorted for reuse where condition allows. Reclaimed handmade clay tiles, common on older Suffolk properties, are particularly worth keeping if they're sound, because matching them with new stock can be difficult and expensive.

Once stripped, we inspect the rafters. Any that are split, weakened by woodworm or carrying rot get replaced at this stage, because once the new roof goes on there is no cost-effective way to reach them again.

Stage 3: New Underlay, Battens and Tiles

Modern breathable roofing membranes replace the old bitumen felt that was standard for decades. Breathable underlay allows moisture vapour to escape from the loft space rather than condensing on the felt and dripping back - a meaningful improvement for insulated loft rooms especially.

Battens are fixed horizontally across the rafters at the correct gauge for the tile being used. Gauge - the exposed face of each tile - must be precise; get it wrong and tiles won't sit flat or interlock correctly. New tiles are then fixed from eaves to ridge, with every course checked for line and level.

Ridge tiles are bedded in mortar or, increasingly, secured using a dry-fix mechanical system that eliminates the cracking and blow-outs that eventually affect mortar ridges in exposed positions. We also check and replace any lead work around chimney flashings and valleys at this stage, since disturbing the surrounding tiles gives the ideal opportunity to do it properly.

Stage 4: Finishing Touches and Clearance

Valley trays, hip irons, finials, verge clips and ventilation tiles all go in before the scaffold comes down. We also inspect and, where needed, replace fascias, soffits and guttering at this point - the scaffold makes it practical, and fascias on a thirty-year-old house often need attention by the time the roof does.

A final walk-round with the homeowner on-site is standard practice. We check the gutters are clear of tile dust and debris, confirm all lead is dressed correctly, and go over anything that needs pointing out before we sign off.

Do You Need Planning Permission?

Most like-for-like roof replacements in England fall under permitted development and do not require planning permission. However, if your property is in a conservation area - and parts of central Bury St Edmunds are - or if it's listed, you should check with West Suffolk Council before changing roof materials. The government's planning portal sets out the rules clearly, and we can advise you on this during the survey.

Choosing a Contractor

Use a contractor who carries public liability insurance and provides a written specification before you agree to anything. Avoid any contractor who asks for full payment upfront.
