Work within your comfort zone if you DIY
As a rule, steer clear of any work that feels dangerous or requires skills that you just don't have.
- For example, if heights make you dizzy or if you're unsteady on your feet, stay off the roof.
- Don't undertake any job that your local building code says must be done by a licensed professional and requires a permit. If you're caught, you may have to pay significant fines and then have the work redone by pros. Even worse, if your home sustains severe damage, as in a fire, your insurance company won't pay out if you haven't followed codes.
