Roof replacement or repair?

Some older house roofs in South Africa need a replacement instead of repair. A home inspection will help identify if roof replacement or roof maintenance is the best choice.

Much of South Africa’s housing stock is within the older suburbs, which were established before or soon after the Second war. These houses are now 60 years old – or maybe older. Roof replacement – either of just the roof covering, or the whole roof structure – becomes an opportunity for these homes – especially if the roof has not been properly maintained over the past half-century.

Regular monitoring of the roof covering and timber structure, combined with timely maintenance will prolong the lifetime of a roof. However, if roof sheeting has been allowed to rust; if tiles or slates are broken, if the flashing has failed and if water has penetrated the roof cavity, then ultimately it’s going to be less expensive to exchange instead of repairing the roof. There comes a time when ongoing maintenance costs may exceed that of replacement.

Tremco’s home inspectors are trained to gauge a roof structure and advise whether maintenance and repair or replacement is that the best choice.

Signs of a roof in distress include a plethora of leaks – old and new – and a sagging roof.

Replacement of a roof offers the chance for homeowners to think about different roof coverings. Possibilities include high-tech coated metal sheeting, new clay or concrete tiles, fibre cement slates, or bituminous shingles laid on a board substrate. Changing the roof covering can dramatically alter the design of the house and its thermal qualities.

A good roofing contractor will assess the power of the prevailing structure to accommodate the load of the covering.

Replacing a roof also offers a chance to properly insulate the roof space. Old South African roofs are rarely properly insulated. In winter the warmth from the house escapes through an un-insulated roof space and in summer the air within the same roof cavity usually becomes extremely hot and heats up the rooms below.

Insulation options which may be considered if a roof is to get replaced include:

Installation of an insulating and moisture-proofing membrane – usually a mixture of plastic and aluminium – directly under the roof covering.
Installation of roof ventilation.

Ceiling insulation.
Homeowners should select a roofing company with a proven diary because the replacement of an existing roof may be a tricky and demanding undertaking. counting on the structure it’s going to rather be possible to exchange the roof covering without interfering with the ceiling, interiors and electrical and plumbing installations. an honest roofing contractor is going to be ready to advise during this regard.

If the prevailing roof is asbestos sheeting or slates, then a roofer who is additionally an approved asbestos removal contractor is required.

Re-roofing involves performing at heights and is dangerous if the contractor and workmen aren’t experienced. Homeowners are ultimately liable for the security of workmen on their property. Unless the building contractor is correctly insured and registered, the homeowner could also be responsible for costs and claims resulting from injuries or deaths during the re-roofing process.

It is therefore important for homeowners to properly screed contractors before awarding them any construction work.
