Roof Replacement Andover

The bitumen felt beneath most twentieth-century roofs becomes brittle earlier than the tiles above it, and tears at every lap, admitting water to the battens. A roof inspection from within the loft establishes its condition before any decision to strip and renew.

Andover’s expansion-era estates account for much of that stock, felted within a few years of one another, so a perished roof there is rarely an isolated case.

A leak too minor to stain a ceiling can saturate the same rafter or valley board for years. The deterioration is apparent only once the tiles come off, and replacement is the stage at which those timbers come out. Where a rafter has lost its strength, new timber is sistered alongside it before the battens are set out.

Around Andover’s old centre stand roofs of the Georgian and Victorian period. A small leak there has had over a century to work on the rafters.

Roofs patched by successive contractors carry mismatched tiles, sealants and flashing details, each of a different age. The layers beneath a patch cannot be assessed until it is lifted, so a full strip removes every patch and the roof is relaid in one covering on new battens.

Many of Andover’s town-centre buildings have been rebuilt more than once since the town began to grow. Their roofs carry patches from successive owners.

Roofs from the post-war decades frequently incorporate asbestos cement in undercloaks, soffit boards or verge details, invisible until the tiles come off. Our team is trained to identify it, work stops around it, and a licensed contractor carries out the removal. The verge and soffit details are then rebuilt in new timber.

Andover built thousands of homes at speed during its 1960s overspill expansion, so these details repeat across whole streets built in that period.

Lofts beneath older impermeable felt exhibit black mould and damp timber on the coldest mornings, because moisture from the household cannot pass through it. A replacement installs a breathable membrane permeable to that moisture, and a ventilated ridge at the head of every slope. Damp timber found at the same time is replaced before the membrane goes down.

In the tight lofts of Andover’s expansion-era semis, the original impermeable felt still traps each winter’s moisture.

The scaffold, the skip and the first deliveries of battens, underlay and tile arrive at times and locations agreed beforehand. You move garden furniture and vehicles clear of the working area before the first morning. Our team manages everything else on the schedule.

The morning forecast determines how many courses come off, and no more is stripped than new underlay and battens can close by evening. Any section not reached is left weathertight, so the loft and the ceilings beneath it are protected overnight.

If the strip-back uncovers a rafter, purlin or flashing detail beyond the quote, work there stops until you have seen it and agreed the price. A written note records any further work before it proceeds. No item appears on the final invoice without your approval.

Underlay, battens, flashings and the new tiles go on in that order, each course lapping the one beneath. Whether the specification is tile roofing or natural slate, each slope is completed and its ridge and verge detailed before the next is started.

A director walks you round the finished roof from ground level and hands over the written documentation for the work. Our team removes the waste and clears the new gutters, and the scaffold is booked off site once the final check is signed.

Four factors determine the cost of a replacement:

• The quantity of tile and batten removed, and its disposal
• Any rafter or batten renewal the strip-back proves necessary
• The dimensions, pitch and complexity of the slopes
• The tiles or slates going back on, over new underlay and fixings

A free survey conducted by a director establishes all four, and your written, itemised quote follows within 48 hours of it, with every item priced and no hidden extras.

Yes, and the match is specified at survey. Around Andover’s old centre the houses are Georgian and Victorian brick, and a replacement there is matched to whatever tile or slate the house already carries. Slate roofing is fitted to match the existing dimension and colour, or clay tile to the original gauge and ridge pattern, whichever the roof carries. Across the expansion estates at Picket Twenty and Augusta Park, the profile is measured from the roof before any tile is ordered.

In most cases, no. Where the new roof is similar in appearance to the one it replaces, a like-for-like replacement is normally permitted development and no application is necessary. A listed building is the exception, and consent is required before the covering or the chimney stack details change. Controls in a conservation area differ from one designation to the next, and a change of covering can require consent. We establish which applies at survey, and the quote accounts for it before any work begins.

On an older property it generally is. Andover’s Georgian and Victorian centre and its expansion-era estates carry roofs at the age where individual repairs begin to recur. A replacement adds the layers absent from a roof of that generation, including a breathable roof underlay, mechanically fixed tiles and a ventilated ridge. The fixings then meet current standards across every slope, and the loft has a ventilation path.

Contact us by telephone or through the enquiry form on this website. The free survey is conducted by a director at a time convenient to you, covering the eaves, flashings and loft interior. If the roof retains serviceable life, we recommend a repair and quote for that instead. Otherwise your written, itemised quote for the replacement follows within 48 hours of the visit. We cover the whole of our Andover service area.
