How long should I expect my flat roof to last? Should it last as long as the warranty, should I expect it to last longer, or will it leak before the warranty is up?
These are some of the most common asked questions by business owners and property managers.
In this blog, these questions are answered by a professional and knowledge roofer in the Lower Mainland.
The Life Cycle of Your Roof
The life cycle of your roof depends on two things. The first is: was the roof properly installed in the first place. The second is how well has the flat roof been maintained.
For this blog we will assume the roof installation was done correctly. As a building owner or property manager, your goal is to extend the useful life of your roof. The manufacturer will warrant their roofing materials for a certain length of time depending on the system and materials used. Labour warranties are not as long as material warranties and are usually only 5 to 10 years at the most.
Roofs with 20 Year Material Warranties
But what is a reasonable length of time for a roof that has a 20 year material warranty to last? The answer to that question will vary significantly depending on what kind of regular roof maintenance has been done.
If the roof has not been maintained at all it is not likely it will last 20 years without leaking. In addition, if it hasn’t been maintained properly the material warranty will probably be void. On the other hand if the same roofing system is regularly maintained it could last 25, 30, or even 40 years.
There is a significant difference in the condition of a roof that has not been maintained in 10 years and one that has received yearly maintenance. At Absolute Roof Solutions, we have seen roofs with 20 year warranies that were completely useless after 10 years.
There are many preventable factors that shorten the life of a roof such as: plugged drains, brittle caulking, debris build up, settling buildings, ponding water, moss & algae or other growth on the roof. One of the worst offenders is breaks in the protective UV barrier. The sun does more damage to roofs than anything else so protecting the waterproof membrane is critical.
The Importance of Roof Maintenance
Regular roof maintenance is what keeps these damaging factors in check. By spending a small amount of money every year on scheduled maintenance, not only will you put off the large capital cost of a new roof, you will also prevent the frustration and cost of emergency repairs. Think of it like changing the oil in your vehicle. It doesn’t make financial sense to not change the oil regularly as your vehicle will certainly not last the length of the warranty.
The sooner you start on a roof maintenance program the better. It is never too late. If the roof has been neglected for a long time without maintenance, it is a good idea to have it inspected by a competent roofing company. It may need some restorative work done the first time to bring it back to a point where the roof is sound and water tight and so that regular maintenance will be all that’s needed for years to come.
As a renovator Doug did many rot repairs which gave him a good understanding of where and why buildings leak, and how to prevent it. He realized the need for a different approach to roofing; one that educated the customer enough to make good decisions. With better trained installers and a quality inspection process Absolute Roof Solutions was born…” Read more.
