When is a repair the right answer in Mountsorrel?
Flat roofs in Mountsorrel face the same enemies as anywhere else: rain driven against walls, leaves blocking outlets, sun drying out older felt and frost opening small cracks. People tend to notice when a stain appears on a ceiling after a storm, or when water is still sitting on the roof days after rain.
Mountsorrel's flat roofs are mostly on 1930s semis with flat-roofed garages and kitchen extensions, with plenty on newer estates where the first extension roofs are now being replaced too. The East Midlands is drier than the west of Britain, so most flat roofs here fail through age, UV and poor detailing at upstands rather than sheer rainfall.
How much does a flat roof repair cost in Mountsorrel?
At East Midlands guide rates, a localised patch repair comes to £150–£490 including VAT. 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?
- Upstands, flashings, laps and seams made good
- Repairs with materials compatible with your roof system
- Leak path traced from the stain back to the entry point
- Outlets and gutters cleared while we're on the roof
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.

£150–£490 for a localised patch repair, at East Midlands guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.
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.
Can a GRP roof be repaired?
Yes. The damaged area is ground back, new resin and matting are laid over it and a matching topcoat goes on top. Cracks that keep reappearing along the same line often point to movement in the deck, which needs fixing first.
