FAQ - Roof Repairs

How long is a piece of string? Roof repairs can cost anything between R2,000.00 – R50,000.00. This all depends on what roof type we are repairing and how severe the leak or problem is.

I will tell you what they do not cover – Lack of maintenance. We often get asked by clients if insurance will cover my roof leak cost due to lack of maintenance. The answer is no.

Insurance companies normally cover storm or hail damage. They also cover burglary damage should the intruders come through the roof. Have a chat to your insurance broker and make sure you gain clarity on what you are covered for.

No, not at all.

It depends on the condition of the existing roof. It is sometimes more cost-effective to replace a roof rather than trying to repair or refurbish it. Give our professionals a ring and they will be able to advise you.

FAQ - Waterproofing

In our opinion, the best waterproofing system is a dual reinforced torch on membrane. The torch on system is one of the oldest, most tried and tested waterproofing systems with a track record spanning decades. It can be used for numerous different applications and comes with guarantees from 10 to 15 years. Newer waterproofing technologies have come and gone over the years, yet the torch on system is still very much in use world wide.

This depends on what waterproofing system is being installed. Mostly, waterproofing includes reinforced torch on waterproofing membrane, polyester membrane, polypropylene membrane, acrylic waterproofing, bituminous aluminium coating, cementitious waterproofing, double layer foil underlay, roof paint and so on.

Well I am going to answer your question with another questions – What roof type are you wanting to waterproof? Tiled roof, concrete roof, metal roof, slate roof? Send us an inquiry and we can send through a scope of work for you to follow to waterproof your roof.

Again, this depends on the size of the area and what you are trying to waterproof. Basement waterproofing is probably the most expensive area to waterproof as it is high risk and normally very complex. Followed by balcony decks, concrete slabs and tiled roofs.

Definitely dual reinforced bituminous torch on waterproofing system. But be careful of what brand of torch on waterproofing you are quoted on. As with anything, you get what you pay for. Some torch on products have a high failure rate. Contact us for a list of brands we would recommend for your torch on waterproofing project.

Dual reinforced torch on waterproofing comes with a 10 year guarantee or a 15 year guarantee. However, if properly maintained it can last in excess of 30 years – 40 years.

SBP membrane can last anywhere between 2 years – 5 years, depending on the application type and where it has been applied.
