Flat roof repairs in Perth

In Perth, as anywhere, a flat roof rarely leaks right above the stain. That is why our repairs begin by tracing the water back to where it gets in, whether that's an upstand, a lap, an outlet or a wall above the roof, before we cut back to sound material and repair it properly.

When is a repair the right answer in Perth?

Flat roofs in Perth 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.

In and around Perth, flat roofs are typically found on 1960s and 1970s link-detached houses with flat-roofed garages and porches, and on low-rise post-war blocks of flats. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write.

How much does a flat roof repair cost in Perth?

For Perth we use Scotland rates: £140–£480 is the guide for a localised patch repair, VAT included. 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?

  • Leak path traced from the stain back to the entry point
  • Repairs with materials compatible with your roof system
  • Fixed price confirmed in writing before work starts
  • Inspection of the whole roof, not just the wet patch

Building standards in Scotland

In Scotland the building standards technical handbooks (Section 6 for energy) apply, and the council's building standards service decides whether a building warrant is needed. Like-for-like repairs to a roof covering can be exempt; alterations, structural work and new roofs usually need a warrant before work starts. The domestic roof benchmark is 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. More on the rules.
