When is a repair the right answer in Andover?

Landlords and managing agents in Andover need a repair done properly once, rather than a quick fix that brings tenants back on the phone a month later. We trace the leak to its source and confirm the price in writing, so the repair can be approved and booked without guesswork.

Around Andover, flat roofs are common on terraced streets with flat-roofed rear kitchens and bathrooms and on newer estates where the first extension roofs are now being replaced. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.

How much does a flat roof repair cost in Andover?

Guide price in Andover: £170–£550 for a localised patch repair, including VAT at South East rates. We confirm the price once we've traced the leak or seen the damage.

Which repair materials work with my type of flat roof?

The repair has to use the same system as the roof, because many flat roof materials don't bond to each other and some damage each other.

  • Torch-on felt: repaired with compatible bitumen membrane, cut back to sound felt and lapped well beyond the defect. Torching near timber, insulation or fascias needs care, and some details are better done with cold-applied methods.
  • EPDM rubber: repaired with EPDM patches and the manufacturer's primer and seam tape. Bitumen products and many general-purpose sealants won't bond to EPDM and shouldn't be used on it.
  • GRP fibreglass: the area is ground back, then new resin and glass matting are laid and finished with topcoat to match.
  • Liquid-applied and single-ply: repaired with the same manufacturer's products wherever possible, as mixing systems can affect a material guarantee.
  • Mastic asphalt: cracks and blisters are cut out and made good with new asphalt by an operative who works with it.

A tin of roof sealant or bitumen paint may stop a drip for a while, but on the wrong membrane it makes a proper repair harder later.

What's included?

  • Repairs with materials compatible with your roof system
  • Outlets and gutters cleared while we're on the roof
  • Upstands, flashings, laps and seams made good
  • Fixed price confirmed in writing before work starts

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

Who checks building regulations for a flat roof in Andover?

Where the work needs approval it goes to Test Valley Borough Council building control, or a registered building control approver. We tell you at the survey whether your job needs it and deal with the paperwork as part of the quote.

How much does a flat roof repair cost in Andover?

£170–£550 for a localised patch repair, at South East guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.

Can you repair the roof if the ceiling is already damaged?

Yes. The roof is fixed first so the ceiling can dry out, and then a plasterer or decorator can make it good. Any wet insulation within the roof should be checked, as it may need replacing.

How long does a flat roof repair take?

Most small repairs take a few hours on site once the roof is dry. Larger upstand or outlet repairs can take a day or more, and setting up scaffold or access equipment adds time.
