What's involved

Flat Roofing in your area

Flat roofs are common on house extensions, garages, dormers, and commercial properties throughout the Mildenhall area, and they perform very well when installed using the right system and the correct falls. Problems arise when flat roofs are installed cheaply with inadequate drainage or inferior materials — something we see regularly when we're called out to inspect failed roofs.

We install three main flat roofing systems depending on the application and budget. EPDM rubber membrane is our preferred choice for most residential flat roofs — it's lightweight, flexible in cold weather, and carries a lifespan of 40–50 years when correctly installed. GRP fibreglass is ideal for roofs with complex detailing or where a hard, walkable surface is needed. Traditional felt systems using torch-on reinforced felt are also available for budget-conscious applications or straightforward garage roofs.

All three systems require correct installation — in particular, ensuring adequate falls to drain water away from the roof, properly dressed upstands at walls and parapets, and sealed details at outlets and penetrations. These are the areas where poorly fitted flat roofs fail. We take drainage design seriously and build adequate falls into every installation.

We survey your existing flat roof or new structure, advise on the most suitable system, and give you a written quote. Most residential flat roof installations in Mildenhall take one to three days depending on size and complexity. We carry out the work with minimal disruption and leave the site clean. All flat roofing installations are guaranteed for a minimum of ten years on the system and workmanship.

Flat roof installation in Mildenhall typically costs between £70 and £120 per square metre for EPDM or GRP systems, including insulation and drainage details.

Questions

What people ask first.

Most standard domestic new roofs take three to five working days from start to finish, including stripping, deck inspection, underlay, battening, and tiling. Larger or more complex roofs with multiple hips, valleys, or chimney stacks can take up to two weeks. We'll give you a realistic programme before we start so you can plan accordingly.
If more than 20–25% of the tiles are cracked, slipping, or missing, the felt underlay has failed in multiple areas, or there is rot in the roof timbers, replacement is usually more cost-effective than continued repairs. We'll give you an honest assessment during a free survey rather than recommend work that isn't necessary.
Most standard roof repairs in Mildenhall — including replacing a few tiles, repointing ridge sections, or resealing leadwork — cost between £150 and £600. More involved work such as replacing a full valley or repairing storm damage across a large area typically costs £800–£2,500. We'll give you a written quote after a free inspection so you know the cost before we start.
Flat roof installation in Mildenhall typically costs between £70 and £120 per square metre for EPDM rubber or GRP fibreglass systems, including insulation and drainage detailing. A standard single-garage flat roof of around 16 square metres would therefore cost in the region of £1,100–£1,900 fully installed. Traditional torch-on felt is slightly less expensive, though it carries a shorter lifespan.
For a standard three-bedroom semi-detached house in Mildenhall, fascia, soffit, and guttering replacement typically costs between £900 and £1,800. The price depends on the total run length, whether the rafter feet need any remedial work, and whether you want uPVC or timber boards. We give fixed quotes before any work starts so there are no surprises.
Lead flashing repairs around a chimney stack typically cost between £250 and £600 in Mildenhall, depending on the size of the stack, how much lead needs replacing, and the ease of access. Re-pointing existing sound lead flashing is at the lower end; full replacement with new Code 4 or Code 5 lead is at the higher end. We'll give you a fixed price after inspecting the work.
A full chimney stack rebuild in Mildenhall, including scaffold, brickwork, new pots, flaunching, and lead flashings, typically costs between £1,500 and £4,000. The main variables are the height of the stack above the roofline, the size of the stack in terms of the number of flues, and whether matching reclaimed brick is needed. We provide a fixed written quote before any work starts.
Chimney stack removal to below roofline level in Mildenhall typically costs between £800 and £2,000 including scaffold, debris removal, and patching the roof covering. Larger stacks with multiple flues, or those on taller properties requiring more extensive scaffold, sit at the higher end of that range. We give a fixed price after surveying the stack so you know exactly what you'll pay.
