Roofing an entire home is a pretty large job that most homeowners are not equipped to tackle on their own. However, if you just have a garage or shed that needs a roof, you may be able to roof the building yourself provided you have the required strength, some know-how, and the right tools. Here are a few tips to help ensure your garage roof is installed properly.
Strip off the old shingles.
Until recently, roofers sometimes placed a new layer of shingles over top of old shingles rather than first removing the old shingles. This is no longer a common practice. You might be tempted to save time by shingling over the existing roof, but in doing so, you could cause a few issues.
If the roof has any damage to the underlayment, which is the wood surface to which the shingles are attached, you won't see it if you don't remove the current shingles. The damage will then worsen over time, leading to the need for another roof replacement. Also, nailing shingles to another layer of shingles is often harder than nailing them directly to the roof, so you're more likely to screw up or cause leaks.
Make sure you use a drip edge.
Drip edge is a sheet of either metal or vinyl that you place along the edge of the roof before putting down shingles. Even though this is a garage, drip edge really is needed. It will keep moisture from seeping under the shingles and damaging the edge of your roof. Without drip edge, you may find that your garage roof stops leaking after a few short years.
Don't use nails that are too long.
Garage roofs tend to be thinner than the roofs on actual homes. As such, you should only need 3/4 inch roofing nails. If you use longer nails, they may poke through the underside of the underlayment. Not only will the exposed nails be a hazard in your garage, but when the nail completely penetrates the roof, leaks are more likely.
Wait until you have a few clear days.
Since you have not roofed a lot of structures, you may move more slowly than you think. You do not want to be partway through roofing the garage when it starts raining. So make sure you have a few dry days ahead before you start the roofing project. If you estimate it will take two days, make sure you leave three dry days.
Remember that if re-roofing your garage seems like too much work, you can always hire a roofing company to come do the work for you.
