Flat Roof Replacement - How Do You Know When it is Time?

What You Need to Know About Flat Roof Replacement

Over the past half century the technology surrounding low-slope roof - flat roofs are almost never exactly flat, but rather have a low slope - technology has evolved tremendously. New low-pitch roofs, such as EPDM rubber roofs, are easy to install, easy to repair, and quite long lasting. Older roofs may or may not need to be replaced when they have problems. 

Here is what you should consider about flat roof replacement:

How Old is Your Roof?

Any roof can be repaired and maintained. If the necessary work will be long lasting and cost effective then repair should be chosen over flat roof replacement. Here are some typical low-slope roof types and their average lifespan:

  • Asphalt (AKA Hot Tar Roof) - 36 years
    • This type of roof is rarely installed these days, and is being phased out. It can be repaired, but will need to be replaced sooner or later.
  • Bitumen Felt - 19 years
    • This type of roof is uncommon, and has too short a lifespan in our opinion. 
  • PVC - 27 years
    • Strong roofs with a good lifespan, but they are expensive to install and difficult to repair. 
  • EPDM - 25 years 
    • The best roof for your money. Their lifespan can often far exceed this average, and best of all they are quite easily maintained. 

Figure out how old your roof is, and see how it compares to the average lifespan for a roof of its type. Again, these are averages, and all of them can be exceeded when proper maintenance is done, which we will talk about next. 


The Effectiveness of Maintenance

One thing we always always say to people is that no matter what, you will only help your bottom line and the lifespan of your roof with proper and timely maintenance from a qualified professional. Problems ignored become problems expanded. A professional roofing contractor will give you the analysis you need of the condition of your roof, and whether you need maintenance or a flat roof replacement. 



Here are some common problems that cause leaks:



Do You Need A Flat Roof Replacement?

Maybe, but maybe not. What you need to do is consider the age and condition of your roof. Never ignore problems with your roof because they will only get worse and more expensive over time. Call a qualified roofing contractor and have your roof inspected, maintained, and if needed talk about replacement options.
