A new roof on your East Dereham home is a significant investment, and the right aftercare will keep it performing well for decades.

A full roof replacement starts with stripping the existing covering back to bare timber. The structure is inspected - every rafter, purlin, and batten - and any rotten or weakened timber is replaced before anything else goes on. New breathable underlay, treated battens, and the chosen tile or slate go on in sequence. Ridges are dry-fixed mechanically, flashings are set in lead or approved alternatives, and all valleys and abutments are sealed and dressed properly.
The result is a roof that, with straightforward care, should serve the property for many decades. But "straightforward care" is not the same as "no care at all". A few simple checks each year will catch small issues before they become expensive ones.
Most roof failures that appear a few years after installation are not caused by defective materials or poor workmanship - they are caused by things that have landed on, grown on, or washed down the roof in the meantime. Debris accumulates in valleys and gutters, moss establishes itself in shaded areas, and flashing can work loose at junctions if it is not checked periodically.
None of these problems are serious if caught early. All of them can become serious if ignored for several winters.
Blocked gutters are the most common cause of avoidable roof and wall damage in UK homes. When a gutter overflows, water runs down the fascia, soaks into the soffit, and works its way into the wall or roof structure over time. On a pitched roof, this can saturate the first course of tiles and the underlay behind the fascia board.
Gutters should be cleared of leaves and moss at least once a year, ideally in late autumn after most leaves have fallen. If there are large trees close to the property, a second clear in spring is worth doing. Check that downpipes are running freely by pouring a bucket of water into the gutter at the high end and watching it drain. Any standing water after rain points to a blockage or a gutter that has dropped out of fall.
You do not need to get onto the roof to carry out a useful check. From ground level or an upstairs window, look along the roof surface for any tiles that are lifting, slipping, or sitting at an odd angle. Check the ridge line - it should be straight and level. Any sag or dip in the ridge or the main roof slope is worth investigating.
From inside the loft after heavy rain, look for any water staining on the underlay or on the timbers. A small wet patch that dries out quickly is not necessarily a crisis, but the same patch growing larger over several months is a sign that something is getting through.
Moss establishes itself most readily on north-facing slopes and in shaded areas. Left unchecked, it holds moisture against the tile surface, accelerates frost damage, and can lift tiles slightly as it grows into the laps. A biocide treatment applied by a roofer or a specialist cleaning company will kill the growth without damaging the tiles. Physical removal - sweeping or pressure washing - can dislodge granules on concrete tiles and force water under slate, so it is generally not recommended without professional advice.
Zinc or lead strips fitted near the ridge can slow moss regrowth, as rainwater washing over the metal inhibits the organisms that start the growth cycle. This is not a replacement for periodic treatment but can extend the interval between treatments.
Lead flashings around chimney stacks, dormer walls, and at roof-to-wall abutments are the joints most likely to fail over time. Lead is durable, but it does move with temperature changes, and if it has been over-tacked, cracked, or poorly fitted, those junctions can open up over years.
Check visually that flashings are sitting flat and that no edges are lifted or cracked. Mortar pointing on a chimney stack should be checked every few years - the exposed position means frost action will work the mortar out faster than anywhere else on the house. Crumbling or missing pointing lets water track down inside the chimney and into the stack.
A new roof installed with a breathable underlay still needs adequate ventilation at the eaves and ridge to keep the roof space dry. If ventilation is restricted - by insulation pushed too far to the eaves, or by blocked soffit vents - condensation will build up in the roof space and eventually cause the timbers to deteriorate from below.
If you have had new loft insulation installed since your roof was replaced, check that the insulation does not block the eaves gap. The recommended clear gap at the eaves is at least 50mm. Soffit vents, if fitted, should be visually clear and not painted over.
Running through this list once a year - or after an unusually severe storm - takes less than 30 minutes and will flag anything that needs attention before it becomes a repair bill.
If you spot anything on your checks that you are not sure about, call a roofer to take a look rather than leaving it. A brief inspection to identify a problem costs far less than waiting until the problem has spread to the structure below. Water damage to timbers, insulation, and ceilings is always more expensive to put right than the roof defect that caused it.
