There are two ways to insulate a flat roof. The warm roof method places the insulation on top of the roof deck, below the waterproof layer. The cold roof method places it between the ceiling joists, under the roof deck.
Every homeowner loves a bargain, but a roof is not the place to hunt for one. It keeps out rain, wind and frost, and it protects everything underneath it. When the lowest quote on the table comes from an unknown tradesperson, the real cost tends to arrive later, as leaks, callbacks and a second bill. For homeowners and landlords looking for local roofers in Essex, the question worth asking is not "who is cheapest?" but "who will still stand behind this work in five years?"

Repair is the right call when the damage is localised, the rest of the roof is sound, and the repair cost stays well under 20–30% of a full replacement. Replacement becomes the smarter option once a roof is past 25–30 years old, has had three or more separate leaks in the past two years, or shows signs like daylight through the loft, a sagging roofline, or widespread tile damage.
Most new roof installations in the UK take between 2 and 5 working days for an average semi-detached or detached home. A small roof, such as a garage or extension, can be finished in a single day, while a large or structurally complex roof, particularly one using natural slate, can take up to a week or more. The exact figure depends on your roof's size, the material you choose, the weather during the build, and what's found once the old covering comes off.
