If it’s time to repair or replace your roof, you might be tempted to do it yourself, especially due to the high cost of having it done professionally. However, roofing projects are not easy and can be very dangerous. Depending on how much roofing experience you have and how steep your roof is, you may want to go the professional route. After all, roofing repairs can be pricey but so can medical bills.

If you plan to take on a DIY roofing project on your property, there are a few dos and don’ts to keep in mind before jumping in.

Do consider your options

Before you go DIY crazy, consider the job at hand. If you have to undertake an entire reroofing project, you should at least get a quote from a professional. A big roofing job needs to be done properly because it can directly affect the structural integrity of your home.

However, if you just need to fix a few loose shingles, it’s a little less daunting to DIY. You should also consider the level of danger involved in the project. Some roofs are much higher and steeper than others. If you’ve got an Everest-sized roof, you might want to call in the professionals—or up your life insurance coverage.

Don’t forget to plan ahead

From getting the needed materials to checking the weather forecast, make sure you go into your roofing project well-prepared. Make a checklist of all the items you need to pick up at the local home improvement store and make sure you have everything before starting the project.

You’ll also need to estimate how long the job will take and check out the weather forecast. If it’s a two-day job, you don’t want to be surprised by a monsoon halfway through.

Do keep the worksite clean

Depending on the project, your worksite could get pretty messy. Make sure you keep the area clear of debris and other work materials you aren’t using. When you are walking on a steep roof, things such as nails, stray tools, and even loose shingles can be a major safety hazard. When you are done using a tool, remove it from the area.

Don’t work alone

No matter how simple the task, never work on roofing project alone. Having an extra pair of hands can be helpful when moving heavy shingles or other materials. Nearly as important is having an extra set of eyes to look for potential trouble spots. Plus, if an accident does occur, you’ll have someone there to help.

Do bring along safety gear

As mentioned before, roofing is dangerous, which means its safety gear is necessary. Because most roofs are slanted, you’ll need to make sure you have shoes with a fair amount of traction to keep you from slipping. Professional roofers typically wear soft, rubber-soled boots.

A helmet is another DIY roofing must-have. In case you do fall, wearing a helmet can minimize any head injury you might sustain. Safety glasses and a safety harness are a few other safety items to consider.

Remember, roof work is no Pinterest project. It’s usually best left to the professionals; however, if you tackle it yourself, make sure to be well-prepared and put safety first.
