The Roof Replacement Process, Step by Step

What Actually Happens When Your Roof Is Replaced?

Most homeowners only replace their roof once, maybe twice in a lifetime, so the process can feel like a mystery. Knowing what to expect from start to finish helps you plan properly, ask the right questions, and avoid being caught out by surprises. Here is a plain account of how a roof replacement unfolds in practice, from the first survey to the final clean-up.

Wymondham sits in a part of Norfolk that catches its fair share of wet winters and gusty easterly winds. That kind of weather accelerates wear on older clay and concrete tiles, pointing mortar and lead flashings, so many properties in the town reach a point where patch repairs no longer make economic sense. When that point arrives, a full roof replacement is usually the most cost-effective long-term decision.

Step 1: The Survey and Quotation

A proper replacement starts on the ground, not the ladder. We walk around the property, look at the roof from every angle, and note the pitch, the tile type, the condition of the timber structure underneath, and anything unusual such as chimney stacks, skylights or valley details. We then go up and inspect at close range.

The survey shapes the quote. A Norfolk farmhouse with a steeply pitched clay pantile roof is a very different job to a 1970s semi with a shallow-pitched concrete tile roof. Costs vary widely depending on size, access, material choice and what we find underneath. As a general guide, a full replacement on a standard three-bedroom detached house in this area typically falls somewhere between £5,000 and £12,000, though larger or more complex properties will be higher. We give written, itemised quotes so you know exactly what you are paying for.

Step 2: Scaffolding and Preparation

Safe access is not optional. Before any tiles come off, a scaffold contractor erects a full perimeter scaffold with toe boards and edge protection. This is a legal requirement under the Work at Height Regulations and it also protects your property, guttering and any plants below. In most cases the scaffold goes up a day or two before work starts.

We notify neighbours if access to their land is needed, and we sheet over anything vulnerable in the garden. Roof replacement generates a significant amount of debris, so a skip or trade waste bags are positioned ready before stripping begins.

Step 3: Stripping the Old Roof

The existing tiles, slates or felt are stripped back to the bare rafters. This is the stage that tells us the most about the roof's true condition. Hidden rot in rafters, compressed or perished underlay, and failed fixings only become visible once the covering is removed. If we find rotten timber, we cut out the affected section and splice in treated replacement timber before going any further.

Any lead work around chimney stacks, valleys or parapet walls is also assessed at this point. If you have a chimney that needs attention, it makes sense to deal with it now rather than after the new tiles are down. We carry out lead work as part of the replacement process so the whole roof is finished to the same standard in a single visit.

Step 4: New Underlay, Battens and Tiles

Modern breathable membrane underlay goes down first, lapped correctly and dressed into the gutters. This is a significant upgrade over the old-style bitumen felt common in properties built before the 1990s, which becomes brittle and splits with age. Treated timber battens are then fixed across the rafters at the correct gauge for the tile being used.

Tiles or slates are fixed to the battens, starting at the eaves and working up to the ridge. Ridge and hip tiles are traditionally bedded in mortar, though mechanically fixed dry-fix ridge systems are now widely used and perform well in exposed Norfolk conditions. Every course is checked as we go rather than inspected at the end.

If your fascias or soffits have deteriorated, replacing them at the same time saves a second scaffold hire. Our team handles fascias, soffits and guttering alongside the main roof work so the whole front elevation is finished together.

Step 5: Clean-Up, Check and Sign-Off

Once the new roof is complete, all debris is removed, the scaffold comes down, and we carry out a final inspection at ridge level before leaving site. We check the ridge line, all verge details, lead flashings, any valleys and the gutter line. You should receive a written record of the materials used, including the tile manufacturer's details, so you have that information for your own records.

Planning permission is not usually required for a like-for-like replacement in Wymondham unless the property is listed or in a designated area. If you are unsure, the Government's planning guidance sets out when consent is needed. It is always worth checking before specifying a material that differs significantly from the original.
