When does a garage roof in Dover need replacing?

Many garages in Dover still carry their original mineral felt, which may have been patched several times. Once the chippings have washed off and the laps have split, water gets under the felt and into the deck, and patches stop holding. At that stage a full replacement is the practical fix.

Around Dover, flat roofs are common on terraced streets with flat-roofed rear kitchens and bathrooms and on bungalows with flat-roofed side extensions and dormers. 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 long does a garage roof replacement take?

A single garage roof is typically finished in one or two days, and a double garage in two or three, weather permitting. Deck repairs and new fascias add time.

Disruption is light. You will need to empty or cover anything stored in the garage, because dust and debris can fall through gaps in an old deck during the strip. The garage door may be out of use for part of the job, and the car is best parked elsewhere so a skip can sit on the drive. We keep the roof weathertight at the end of each day.

What's included?

  • Written workmanship guarantee, with material guarantees registered where available
  • Replacement of soft or swollen deck boards
  • Gutter or outlet renewed where the old one has failed
  • New membrane dressed into fresh edge and drip trims

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.

Is it worth repairing a garage roof instead?

If the roof is generally sound and dry with one isolated defect, a repair is usually sensible. Widespread cracking, a soft deck or repeat leaks point to replacement.

How long does a garage roof last?

It depends on the system. As indicative figures, EPDM lasts 25–50 years, GRP 20–40 and modern torch-on felt 15–25, with good specification and maintenance.
