How to repair a flat roof

How to repair a flat roof

How you approach the flat roof repair will depend on many factors. The type of existing roofing materials needing repair, the condition of the substrate and even the weather will need to be considered before you go ahead.

Preparing and repairing the flat roof substrate

The underlying substrate of the flat roof should be in a good condition, with no rotten timbers. Any decayed and wet timbers should be replaced. (Standard 18mm OSB3 sterling board or plywood is commonly laid at right angles to joints).

Self-drilling countersunk screws should be used. Under no circumstances should nails or staples be used for fixing of a timber substrate. These fastenings are inclined to work loose and risk damaging the roof covering. The substrate finish should be smooth, and free of sharp edges, wood splinters or other protrusions. All rough surfaces that could potentially damage a membrane, for example, should be isolated or removed completely. The roof surface should also be dry, as any moisture present could lead to a poor-quality repair, particularly in membrane adhesion and blistering.

All surface areas should be swept clear around the site of the repair. Remove debris, dust and any other loose particles. Once the roof has been properly prepared and has a clean, dry substrate, the repair can take place.

Repairing a flat roof

Repairing a flat rubber roof

Although EPDM is hardwearing and reliable, it can still be as vulnerable as any other roofing material in exceptional circumstances such as storm damage or a break-in. Repairing a flat rubber roof can often be a straightforward, simple repair process using cold application methods and the correct products.

Flat roof patch repair products are ideal for DIY repairs to small tears or holes in rubber roofing membranes. We also provide a range of tapes and accessories for other types of repairs, such as:

  • Leaking skylight or failed seal
  • Repairs to pipe flue seals
  • Flat roof flashing repairs
  • And more.

For flat areas, the membrane can be easily repaired with a piece of Quickseam SA flashing. For damage at angle changes, a Quickseam Corner Flashing patch must be used instead.

Repairing leaks in other flat roof materials

Permaroof Roof Repair liquid provides a long-lasting, reliable seal over a variety of substrates and common flat roofing materials, such as:

  • Bituminous coatings
  • Single and double-ply membranes
  • Felt
  • Concrete
  • Timber
  • Metal
  • And more.

Small cracks and splits, holes or tears can be addressed quickly in many cases using liquid PU in this way. Fast and easy to apply using just a good quality paintbrush, this pre-accelerated product is ideal for a quick, yet lasting approach to your DIY flat roof repair.

Consider the weather

Care should be taken when using adhesives, sealants, QuickPrime Plus and other flat roof repair products in cold weather below 10°C. It is necessary to store these products at room temperatures before use. Do not allow water-based bonding adhesive to freeze.

If temperatures are likely to fall below freezing in the first 48 hours after application, use a solvent-based bonding adhesive over water-based products.

Certain combinations of temperature and humidity may cause condensation to form on the surface of rubber roofing membrane. If this occurs, it may be better to opt for a temporary flat roof repair until the ambient weather conditions improve.

Emergency flat roof repairs

Emergency Flat Roofing Repairs

If you need to make flat roof repairs quickly, Permaroof Emergency Roof Repair may be the product for you. The liquid PU solution can be applied to a wide range of surfaces including felt, bituminous coatings, concrete, EPDM membrane and more. Even if it rains after application, the waterproofing will not be affected.

Temporary Flat Roof Repairs

Sometimes a temporary flat roof repair is needed to block a leak. This could be until planned works take place or while you wait for a professional appraisal and quotation.

Permaroof Emergency Roof Repair is suitable for a wide range of substrates and materials. Although it provides a long-lasting, reliable seal, this product is also ideal for a temporary flat roof repair.

Preventing flat roof repairs

It is worthwhile keeping an eye on flat roofing around the home and outside buildings to avoid an emergency roof repair and the associated costs. A simple, visual inspection, particularly following inclement weather or storm conditions, can highlight areas that may require further inspection or attention.

Flat roof repairs can often be fixed quickly and easily if they are caught early enough and pre-empting a potential failure is even better. Visually inspect your flat roofing from above, ideally from an upstairs window and also from inside the property and be prepared to act fast if you see any signs of a leak.

Warning signs of a failing flat roof

  • Ponding – when water forms puddles across the flat roof – this can also be a sign of a failing roof deck.
  • Bubbles forming – certain types of roofing and felt coverings swell in heat and form bubbles, which then dry out, crack and let in water when it rains.
  • Tears and cracks – if you find a tear or crack in any type of material on your flat roof, repair it quickly.
  • Damp patches on the ceiling or upper walls
  • A damp smell
  • Internal mould or mildew
  • Excess condensation around the windows

It is vital that you maintain gutters around the property and keep them clear of leaves and other debris that can commonly cause clogging. A leaking roof caused by overflowing, clogged gutters is commonplace across the UK so it is important to inspect them regularly.

Permaroof has an innovative product in stock that can help prevent many common flat roof repairs. The Gutterbrush is designed to keep debris out of the gutter, while allowing water to pass through the polypropylene filaments and flow away through the drainage system. Available in two sizes – 100mm and 150mm.

Preventing Roof Repairs Caused by Gutter Leaks

A leaking roof caused by overflowing, clogged gutters is commonplace across the UK. Clearing gutters every year is an essential, yet time-consuming and sometimes hazardous task for homeowners, who often engage professionals to do it for them.

Permaroof has an innovative product in stock that can help prevent this annual chore for many years. The Gutterbrush is designed to keep debris out of the gutter, while allowing water to pass through the polypropylene filaments and free flow away through the down pipes. This prevents not only clogging of the gutters, but also of the drainage system. Available in two sizes – 100mm and 150mm.

Permaroof UK has one of the largest stocks of EPDM flat roofing products in the country and puts customer support at the forefront. Buying flat roofing from Permaroof offers peace of mind for both trade and DIY roofers – both in quality products and customer service.

When and how to call in an expert

Professional Roofing Repairs or DIY?

It is worth reminding yourself that you are working at height and could be injured even if working on a single-storey garage flat roof repair. Falls from height are common in the DIY sector, and safety should always come first.

If you aren’t confident working at height as a DIYer, realise your limits and call in a professional roofer to carry out your flat roof repair. An experienced roofer may not charge as much as you think for a simple repair to your rubber roof membrane, for example. Bear in mind that an emergency, out-of-hours call out will cost more than a scheduled, quoted repair.

For roofing repairs with liquid membrane, we recommend Permaband Matting. It is embedded into a coat of Permaroof 500 (available here).

Flat roof repairs – Do-It-Yourself?

We stock a range of excellent products that can make light work of a flat roof repair for DIY. Liquid EPDM membrane can provide a quick, emergency seal that is effective and long-lasting. Such roof repair systems are ideal for the DIY market, as they are easy to apply and cure quickly without professional assistance. EPDM rubber membrane is also straightforward to repair using adhesives and patches in a similar method to repairing a puncture on a bicycle wheel.

While these types of rubber roofing membrane repair are straightforward to carry out, it is important to remember that the seal must be watertight and the patches you have applied, perfectly adhered. Critical repairs to flat roofing must be carried out to a high-quality and if you aren’t sure you can create a perfect seal, it is wise to call in a professional, insured roofer to repair the membrane.
