What's involved

Flat Roofing in Lowestoft

Flat roofing covers extensions, rear additions, bay window tops, porches, garages, and flat-roof bungalows — all common across Lowestoft's housing stock. A failed flat roof, whether it's an old felt system that's split or a poorly installed replacement that's pooling water, is one of the fastest ways to cause serious damage inside a property. For new flat roofs and full replacements, we install GRP fibreglass and EPDM rubber membrane systems. GRP (fibreglass) is our most popular option for domestic extensions — it's seamless, highly durable, and carries a 25-year product guarantee. EPDM is a single-ply rubber membrane that works well on larger areas and is particularly resistant to the UV exposure and temperature fluctuations you get in a coastal climate. For straightforward repairs to existing torch-on felt systems we can patch and reinstate without necessarily replacing the whole roof area. Avoiding a flat roof specialist and going with a general builder who lays standard felt is a false economy. Poor drainage design, inadequate upstands at abutments, and incorrect solar-reflective finishing all cause premature failure. A flat roof that's properly detailed should not need attention for 20–30 years. We survey the existing structure, check the decking and joists for moisture damage, and improve the fall where possible before any new covering goes down. Most domestic flat roof replacements on Lowestoft extensions take one to two days. Larger garage or commercial roofs take two to four days. All work is covered by our workmanship guarantee, and GRP and EPDM systems come with manufacturer product warranties. Flat roof replacement in Lowestoft typically costs £70–£110 per square metre installed for GRP fibreglass, and £60–£90 per square metre for EPDM rubber.

Questions

What people ask first.

Most standard roof repairs in Lowestoft fall between £150 and £600. Replacing a handful of broken tiles is at the lower end, while re-bedding a full ridge line or replacing valley lead work sits at the higher end. We provide a written quote after inspection so there are no surprises.
A new roof on a typical Lowestoft semi-detached house costs between £6,000 and £12,000, fully installed including scaffold and materials. An extension or single-garage roof starts from around £1,500–£3,000. We provide a fully itemised written quote after measuring up on site.
If more than 20–25% of your tiles are cracked, slipped, or porous, the underfelt is visibly breaking down, or you've had repeated leaks in different areas over the past few years, replacement is usually more cost-effective. We'll give you an honest assessment during a free survey — we won't recommend replacement if repairs will genuinely do the job.
GRP fibreglass flat roofing in Lowestoft typically costs £70–£110 per square metre fully installed. EPDM rubber membrane sits at £60–£90 per square metre. A typical 20m² rear extension roof would cost roughly £1,400–£2,200 depending on the system chosen and any decking repairs needed.
A full replacement on a Lowestoft semi-detached house typically costs £900–£2,000 for uPVC fascias, soffits, and guttering. Detached properties or those with more complex rooflines will be at the higher end. We provide a free written quote after measuring around the property.
Chimney repointing and lead flashing replacement in Lowestoft typically costs £400–£1,200 depending on access, stack height, and extent of work. Replacing flaunching and a chimney pot can add £150–£350. We always provide a written quote before starting, and the price includes scaffold where required.
We aim to be on site within three to four hours for emergency call-outs across Lowestoft and the immediate surrounding area. We're available seven days a week including bank holidays. Call our emergency line directly rather than submitting an online enquiry for the fastest response.
For non-emergency leaks we typically carry out an inspection within 24–48 hours and can usually complete the repair on the same visit or return within a few days. If you have active water ingress causing damage inside your home, call us and we'll treat it as an emergency call-out.
