When Is It Time To Re-Roof?
By law, all roofs in New Zealand are required to have a minimum durability of 15 years. It is possible for many roofs to last up to three times longer if the house and roof were designed and installed properly. With sufficient maintenance, the lifespan of your roof can be extended too. Although, all roofs have a finite lifespan and will eventually require a replacement or upgrade. The biggest indicators of a new roof include...
Your Roof Is In Its Twenties
As mentioned, all roofs in New Zealand are required to be built to last a minimum of 15 years. That is the legal minimum, and often your roof can go on for many more years. A quality roof can easily last a good 20 to 30 years, but inspections should be routine when your roof is reaching its late 20’s and on wards. Even 40-year-old roofs can look good from the ground, but there could be a problem. If you live in a development and your neighbours are all starting to replace their roofing, that is a clear warning sign you should consider to do the same.
You Can See Light From Your Attic
It may be an obvious indicator that if light can get in, so can rain and cold air. Checking for light and possible water stains is always a good idea. If any water patches are discovered, watch them over a rainfall and notice if the shape or size alters, this could mean you have an active leak. Depending on the extent of the damage, immediate action is likely required. Small leaks can be patched, but larger ones may be a result of structural damage or old age. It would be wise to call in a professional sooner rather than later.
The Entire Roof Seems Out Of Shape
When the roof is sagging, it can be easy to jump into panic mode. This typically means there is a structural issue. The reason for sagging could be a problem with the attic decking, or it could be a warning sign of an issue with the supports in the foundation. Although you may not be in immediate danger, this kind of thing is easier to take care of when it is small, rather than when it has progressed. Any potential signs of your roof changing shape should mean that it is time to contact an expert as soon as you can.
