Roofs we see in Sunningdale

  • Brick estate houses with concrete tile roofs among pine trees

    Large houses on generous plots

    Many Sunningdale houses are large and set well back in big gardens, and big houses mean big roofs: long ridges, hips, several valleys (the internal gutters where two slopes meet) and tall chimney stacks. Clay and concrete tiles are common. The sheer size makes access and scaffold a real part of the price, which is why we quote after seeing the roof rather than guessing from the street.

  • Brick chimney stack with clay pots

    Apartment blocks along the A30

    The neighbourhood plan for Ascot, Sunninghill and Sunningdale records that along the A30 a number of large houses have been replaced by blocks of flats and apartments. Blocks like these usually carry flat or very low-pitched roofs with parapet walls, hidden gutters and several outlets. They suit single-ply membranes, and they leak where a parapet upstand or an outlet has been poorly detailed, not usually across the open field of the roof.

    The old village around Holy Trinity

    The oldest part of Sunningdale clusters around the listed Holy Trinity Church, and that old village was designated a conservation area in 1995. Houses here tend to be smaller in scale than the big villas, and older roofs commonly pair plain tiles with brick chimneys and lead at the abutments. These are roofs to repair carefully and to match, not to renew wholesale, and the survey photographs help when you talk to the council.

Planning and building control in Sunningdale

The Royal Borough of Windsor and Maidenhead looks after both the planning and the building control side here. The borough lists Sunningdale as one of its 27 designated conservation areas, and its conservation areas page is the place to check whether your road is covered. The old village is grouped around the listed Holy Trinity Church, and Charters, the art deco mansion of 1938 now converted to apartments and a spa, is listed at Grade II.

In a conservation area, like-for-like repair of a roof is generally treated as routine. Altering the covering, the pitch or the chimney may require consent, so have a word with the conservation officer before any materials are ordered, and treat any listed building the same way. Stripping and recovering a whole roof, inside the conservation area or not, is often notifiable to building control, which we take care of. If you are weighing a roof window, our planning permission guide for roof windows covers what applies, and it is stricter here.

What we find on Sunningdale roofs

Sunningdale roofs fail for reasons that follow the place: big complicated roofs on big houses, flat roofs on the newer apartment blocks, pine and oak shade from the heath and woodland nearby, and an old village where the rule is repair and match.

Chapter 1: What lets rain in at the parapet of a flat-roofed apartment block in Sunningdale?

What we find

A parapet is the low wall that rises around the edge of a flat roof, and the junction where the membrane turns up it is the weakest point on most apartment blocks. The upstand (the vertical part of the membrane) can peel away from the brickwork when the adhesive ages, and the coping stones or flashing along the top of the wall can open at the joints. Rain then runs behind the membrane and appears inside as a stain on a top-floor ceiling, often a metre or two away from where the water actually got in.

The roof outlets are the other usual culprit. On blocks of this type the outlets are few and carry a lot of water, so one that is half blocked with leaves lets the roof pond, and standing water finds every flaw in the seams. Pine needles from the neighbouring woodland fill outlets quickly, so the problem comes back unless the debris is dealt with.

What we fix

We start by tracing the water properly: a close look at the upstands, the copings, the outlets and the seams, with photographs of each. A local failure can be cut out and patched, a loose upstand can be bonded back and sealed, and an outlet can be cleared and fitted with a leaf guard. If the membrane is simply worn out across the whole roof, we say so, and quote to strip and re-cover in EPDM (a synthetic rubber sheet) or fibreglass GRP (resin and glass matting that sets hard on the deck).

Cost guides in the UK show EPDM at £80 to £120 a square metre and GRP a little higher, and the fixed quote for your block follows the survey. Block managers can read our flat roofing page, and larger roofs fall under commercial roofing.

Chapter 2: Why do our gutters overflow every autumn, living beside Windsor Great Park and Chobham Common?

What we find

Sunningdale sits next to Windsor Great Park and Chobham Common, and many roads are lined with mature trees. Pine needles, oak leaves and seed cases drop onto roofs all year, and the needles are the worst for gutters because they pack into a dense mat. Water then spills over the front of the gutter and runs down the wall, or backs up under the bottom course of tiles and soaks the fascia board behind.

Shade makes the same roofs damp. A north slope under tall trees stays wet long after the sun has dried the south side, and moss takes hold, lifting the edges of the tiles and holding water against them. You may notice green staining on the wall below an overflowing gutter, a drip at the same spot every storm, or a roof that has gone dark and furry on one slope only.

What we fix

The first job is to clear the gutters by hand and flush the downpipes to make sure they run freely. Where the trees are close, a gutter guard or leaf screen cuts down how often this needs repeating. Any fascia that has gone soft behind a long-running overflow gets cut out and replaced, since it will not hold a gutter bracket for long.

For the moss, we remove it by hand and treat the tiles with a biocide, which is gentler on concrete and clay than a pressure jet that can strip the surface. Hand removal with biocide is reported in UK cost guides at between £748 and £978 for small to large roofs, and our own figure is set after the survey. See our roof cleaning page, and the guttering, soffits and fascias service if the boards need work.

Chapter 3: Where does a big Sunningdale villa roof usually start to leak, with so many valleys and chimneys?

What we find

The more angles a roof has, the more joints there are for water to find. On a large house with hips, valleys and several chimney stacks, leaks seldom start in the middle of a tile slope. They begin at the lead: the valley gutter where two slopes meet, the flashing (the strip of lead that seals the stack to the roof) and the soakers (small lead sheets woven between the tiles up the side of a chimney). Lead lasts a long time but it creeps, splits at the folds, and can be lifted by wind or knocked by earlier repairs.

In the loft you may see a damp trace on a timber below a valley, or staining on the chimney breast. Because these roofs are big and high, a small leak can run unseen for years along rafters before it reaches a ceiling, by which time the felt and battens around it may have rotted.

What we fix

We look at the lead from the roof itself, not from the ground, and photograph every valley, flashing and soaker so you can see the actual splits and gaps. Small failures can be repaired with new lead patches or re-dressed flashings. A valley that has cracked along its length is better replaced, in new lead with the surrounding tiles lifted and relaid, because patching a long run only moves the leak.

If a chimney stack is also loose or its mortar has gone, we do the repointing at the same visit so the scaffold is only needed once. Leadwork on a chimney is reported at £350 to £920 in published guides, and the price we commit to follows the survey. More is on our lead roofing and chimney repairs pages.

Chapter 4: Can the roof of a house near Holy Trinity Church be repaired rather than re-covered?

What we find

Houses around the old village are older and smaller than the villas, and their roofs have usually been patched many times by many hands. Plain clay tiles slip when their fixings corrode, edges flake in frost, and mismatched replacements show up as patches of different colour. Where a roof carries a brick chimney, the mortar around it is often softer than modern cement and the joints open slowly.

Because the old village is a conservation area and the church is listed, the roof is part of what the council is protecting. Homeowners often ask whether it must all come off. It rarely does. The faults tend to be local: a run of slipped tiles above a gutter, a failed flashing, or an area where the underlay has torn.

What we fix

We aim to keep every tile that is still sound, take off only the failed section, and fill the holes with salvaged or well-matched plain tiles. Fresh battens are fixed under the opened-up patch, and the tiles go back on with proper fixings. Brickwork around chimneys is repointed in lime mortar, which lets the old bricks breathe, rather than a hard cement that can trap moisture and make the face spall.

Before anything changes in how the roof looks, the photographs from the survey give you a clear record to show the conservation officer at the borough, and we explain what is a like-for-like repair and what could need consent. Older roofs can shelter protected bats and nesting birds, and if so we tell you how that affects the timing. Our pitched roofing page explains the repair choices.

Sunningdale roofing questions

Why do big roofs with many valleys and dormers on larger houses leak in more places?

Every valley, dormer cheek and abutment is a joint where water has to be carried across, and a complicated roof has far more of them than a simple gable. Each one has flashings that can lift or crack. The survey follows the water path from the loft, so we can find the actual joint at fault and repair it rather than guessing.

Does my Sunningdale road fall inside the conservation area?

The borough names Sunningdale as one of its 27 conservation areas, but the boundary is drawn on a map and your road may or may not fall inside it. Check the Royal Borough's conservation pages or ask its planning team before work starts. If you are inside, tell us when you book and we will recommend like-for-like materials.

Can you re-roof a flat-roofed block of apartments while the residents stay in?

Yes, that is the normal way flat roofs on occupied blocks are done. We agree the access, the sequence and the days with the managing agent first, cover the area being worked on at the end of each day, and keep the stairwells and entrances clear. Drying times and weather decide the order, so we plan it with the building in mind.

Is the work on a listed house in Sunningdale different?

It is, because any change to materials or appearance on a listed house may need consent before you start. Charters, the 1938 art deco mansion, is listed at Grade II, and Holy Trinity Church itself is listed at Grade II. We photograph the roof, recommend like-for-like repair, and give you the report to use with the conservation officer.

Why do roofs near the golf courses and heath hold so much moss?

Sunningdale is surrounded by woodland, heath and golf courses, with Sunningdale Golf Club and Wentworth Golf Club adjoining the village, and the tree cover that comes with them shades many roofs. A shaded slope stays damp, and moss thrives on damp tile. We clear it by hand, treat it with a biocide and clear your gutters at the same visit.
