Once your roof replacement in Thetford is complete, the aftercare you carry out in the years that follow will determine how long the new roof performs before it needs serious attention again.

A new roof is not maintenance-free. The materials are new, the membrane is sound, and the timbers have been checked - but a pitched roof is a system exposed to weather every day of the year. Simple, regular attention catches small problems before they become expensive ones. Neglect after a replacement is one of the most common reasons a roof that should last for decades develops problems in half that time.
A full roof replacement in Thetford covers everything from stripping back the old covering to laying a new breathable membrane and battens and re-covering in slate or tiles. That work addresses the structure. The aftercare is what you do to protect it once the roofer has left the site.
Before the scaffold comes down, walk through a snagging check with the roofer. Look at the ridge - are the tiles bedded evenly, is the pointing neat and unbroken, or is a dry-ridge system neatly clipped? Check that the verge is finished cleanly on both gable ends. Look at any lead flashings around chimneys, valleys or abutments - the lead should be dressed flat against the surface with no lifted edges or gaps at the mortar joint.
Inside the loft, check that the new membrane is visible and neatly lapped with no tears or gaps where sections overlap. The battens should be visible above it, evenly spaced. If there is any daylight visible through the covering at a point where there should not be, raise it before the scaffold is gone. Bringing scaffold back to site is expensive and avoidable if problems are caught at handover.
You do not need to go on the roof yourself - in fact, walking on a tiled roof is more likely to cause damage than prevent it, unless you are using proper roof ladders and crawl boards. What you can do safely from the ground and from inside the loft is enough to catch most developing problems early.
From the ground, every six to twelve months:
From inside the loft, ideally twice a year and always after a period of sustained heavy rain:
Guttering is not part of the roof covering, but it is directly connected to roof health. Blocked gutters overflow - and the water has to go somewhere. On a pitched roof, persistent overflow from a blocked gutter soaks into the fascia board, rots the timber, and eventually lets damp into the roof space at the eaves. After a new roof, clean the gutters at least once a year, and twice if you have overhanging trees nearby.
Check that gutters are running to the downpipe rather than pooling at one end. Gutters sag over time as fixings loosen, and a sagging gutter holds standing water, which breeds moss and accelerates rot in the fascia below. Re-fixing a loose gutter bracket is a simple job; replacing a rotten fascia is not.
Moss growth on a new roof is normal and does not itself cause damage in the short term. Over years, however, heavy moss growth holds moisture against the tile surface, which accelerates weathering and can lift tile edges in cold weather as the moss freezes and expands. Lichen is harder to remove than moss and more aggressive in the way it bonds to the tile surface.
If moss builds up significantly in the years after a replacement, a biocide treatment - applied from a roof ladder by a roofer, not by pressure washing from the ground - is the safest way to deal with it. Pressure washing a tiled roof loosens the sand and cement on mortar-bedded details and can dislodge tiles. It is not a recommended approach. Some tile manufacturers include a biocide treatment in the tile coating that slows moss growth on newer products.
Lead flashings are one of the most important details on any pitched roof. At chimneys, valleys, dormers and abutments, lead is what keeps water out at the joins between different planes or between the roof and a vertical surface. Lead moves with temperature changes - it expands in summer and contracts in winter - and over many years this movement causes fatigue at bends and folds.
On a new installation, lead should be fixed with clips rather than nailed or bonded solidly, which allows it to move without cracking. After a replacement, check lead details visually each year. Lifted edges, cracked folds, or mortar that has opened at a chase are early signs that a reflashing is needed. Catching a lead failure early - when it is a re-dressing job - is far cheaper than dealing with it once sustained water ingress has rotted the timbers beneath.
Chimney stacks need attention even on otherwise sound roofs. The pointing on a chimney (the mortar between the brickwork) and the flaunching (the sloped mortar bed that holds the chimney pots) deteriorate separately from the roof covering and need checking every few years. Cracked flaunching lets water into the brick core of the stack, which can cause internal damp without any obvious external sign until the damage is well established.
Ridge tiles, whether mortar-bedded or fitted with a dry-ridge system, should also be checked periodically. On a mortar-bedded ridge, the pointing can crack and open up within five to ten years if the original bedding was not adequate. Dry-ridge systems with mechanical fixings are generally more durable in this respect, but clips and seals on dry-ridge systems can also loosen over time and should be looked at if any ridge tiles appear to have lifted.
Not every roof issue needs urgent action, but some do. Call a roofer promptly if:
Most of these are small jobs when caught early. Left for a winter, all of them can become significantly more expensive. A single cracked tile that lets wind-driven rain onto an exposed felt section can, over a few months, result in timber replacement work that dwarfs what the tile repair would have cost.
If your property has flat roof sections - a garage, a rear extension, or a bay top - these need slightly more frequent inspection than a pitched slope because water does not shed as quickly. Check felt or EPDM surfaces for blistering, ponding, or open seams, particularly at upstands where the flat roof meets a wall. Clear any debris from around outlets or the perimeter so water drains freely.
We carry out roof replacements across Thetford, working out of our base in Bury St Edmunds. If you have had a replacement done recently and want a professional eye cast over the detail, or if you are seeing early signs that something needs attention, call us to arrange a roof survey and we will give you a plain-English report on what we find.
