Most roofs will eventually leak, and when your roof leaks, you start to panic and trying to decide what to do. Here you will learn how to repair most common roof leaks yourself, using the materials and tools easily obtainable from your local home improvement store.
If you are not the DIY (do-it-yourself) type of person, or are afraid of heights, this site will still be beneficial to you as you will learn how a roof repair should be done, so when you hire a roofing contractor to fix your roof, you will be able to tell if they did a good job.
Most common roof leaks and types of roof repair:
Most roof leaks are similar in nature and most roofs usually leak due to same type of problems. These include:
- Blown off or missing shingles
- Bad or leaking pipe flashing
- Chimney / Skylight step flashing
- In valleys
- Due to Ice Dams
- Low slope / inadequate roof pitch.
Some roof leaks are more complicated than others and may be difficult to diagnose and repair, in which case you would need to hire a professional roofing contractor. Some roof leaks cannot be simply repaired and may require a roof replacement, which can be costly. However if a roof can be repaired, it is better to fix it and get a few more years out of it.
Situations when a roof cannot be repaired or repairs are too costly usually involve low-slope roofs, with roof pitch below 3″ over 12″, with asphalt shingles installed on them, or when there are massive ice dam leaks (note that Ice and Water shield is not the magic solution for most ice dam roof leaks, contrary to what roofing manufacturers say).
The cost of replacing a roof can vary greatly, and it all depends on the roof in question, where you live, roofing materials used, roofing contractor you choose to install your new roof, as well as many other factors. Use this RoofingMaterialsCalculator.org to estimate your installation and materials cost.
Blown off or missing shingles:
Shingles typically disappear off your roof, because they were either installed improperly (not enough nails, low or high nailing, crooked nailing, etc.) or because your roof is too old and shingles dried out and became brittle.
Leaking pipe flashing:
Sewer vent pipes, also known as stink pipes, require a special flashing boot around them so that they do not leak. Often the rubber gasket around the flashing dries out, or the flashing was installed incorrectly, and the roof starts to leak around the pipe. Another possibility is that the pipe itself has a crack somewhere between the walls, and rain water that gets in the pipe, leaks through the crack. In this case a simple “U” elbow on top of the pipe will solve your problem.
