It’s just a plain fact that all roofs, no matter what type of roofing materials they’re made from, will in time wear out, and require replacement. Even so, as your roof moves into the late stages of its service life, you can expect that leaks will pop up from time to time. Even the best of roofs with the longest service lives will go through this problem stage eventually.
Now what you don’t want to do when you climb your ladder to do repairs, is cause more damage. It’s easier than you think. For instance, if you have cement or ceramic tile shingles you can make things worse just by walking around and breaking tiles. Also, you may be inclined to start pulling off worn looking asphalt shingles or cuddled up built up roofing. Don’t do either!
Another common mistake is to drag a nice big bucket of black patching mastic up top and go crazy with it, going up any area that looks worn, or aged. Don’t do that either because more than likely what you’ll end up creating with gobs of mastic, is water traps. Little areas where the mastic functions prevent water from flowing off your roof.
The fact of the matter is that all roofs other than some of the newer membrane style roofing systems are designed to shed water, not to contain it. So take a good look at your flat roof after a good rain to see of there are any areas where water is pooling. Now if you do find any you have a problem that needs to be resolved and you can do it by bracing up the sagging area from inside your attic or filling it in with roofing material.
Next on your agenda should be to systematically go around and check every drain, or drainage “area.” This would include any downspouts, valleys or any other areas where water is being directed to flow off the building. It’s these zones where even a small crack or worn spot can be the source of larger leaks due to the higher volume of water that flows over them. Drains, in particular, tend to be the source of problems.
The problem with drains or anything else made out of metal for that matter, is that asphalt tends to form weak bonds with it in a flat built-up roofing. Then to add to the problem metal and asphalt expand and contract at different rates in hot and cold weather, and that too leads to separation. Also as far as drains and valleys are concerned, the water itself tends to leach the plasticizers out of asphalt over time.
Whatever you do, don’t rush into the job. Instead take your time as you look over the whole roof with a notepad so you can write up a map that details every leak you find, as well as areas that look like they need some maintenance. Then after you have completed that initial task, your next job would be to become familiar with common repair methods, and materials used by professionals.
Learn about professional roof patch techniques like what roofers call “three-coursing.” Three coursing uses mastic and fiberglass webbing to build up a three layer patch that far outlasts plain mastic alone. Then there are new liquid rubber compounds that can be rolled or poured over questionable areas, and that cure up to form a water tight seal that lasts up to seven years.
One critical fact you have to keep in mind though as you go about the task of repairing any aging roof is that all of them have what is called a “service life” span. Now the longest rating for the best asphalt based materials is 25 to 30 years, but newer systems can go as high as 80 years now. What this all means, is that in the end there will come the point in time when your roof will need to be replaced.
