Many homeowners love to take a DIY (Do It Yourself) approach to as many of their necessary home repairs and renovations as they can get their hands on. But there will always be certain kinds of projects that are best considered "DDIY" (Don't Do It Yourself) jobs. Here are some repairs you'll want to keep a safe distance from. 

Roof Repair

If you ever watched a residential roofing technician up on the roof and said to yourself, "That looks dangerous," your assessment was absolutely correct. Roofing is hazardous work -- so much so, in fact, that's been identified as the sixth most physically risky job in the U.S., with an injury rate nearly 6 times that of the average worker. It's all too easy to slip and fall off of a roof with loose or slick shingles. You might not even make it onto the roof at all if your ladder tips over while you're making the attempt. Leave this kind of work to an experienced roofing contractor.

Roofing contractors like those at Drey Roofing are not only trained to perform the job safely and carefully, but they can also pick up on countless little details that the untrained eye could miss, such as tiny holes in the flashing that might promote leaks. A skilled roofing contractor will also avoid amateurish, potentially destructive errors such as "shiners" (inaccurately driven nails that extend into the attic pointlessly, collecting water condensation that can cause ceiling stains). Professional roofing contractors also guarantee their work and fix errors free of charge.

Garage Door Spring Replacement

Garage doors usually provide several years of reliable service before bits of them start to go bad from wear and tear. Some of the issues, such as a dry chain that needs lubricating, a rail that needs cleaning or a malfunctioning garage door opener, are perfectly reasonable DIY projects. Replacing a broken garage door spring, however, belongs in the DDIY category. These springs do their job by holding tremendous amounts of tension -- tension you definitely don't want released against you or any innocent onlookers at point-blank range.

The two principal types of garage door springs are the torsion springs positioned above the door and the extension springs on each side of the door. Torsion springs that suddenly break can actually kill or maim you, while extension springs that break while not restrained by a safety cable can go flying, injuring anyone in their path. Always leave the garage spring work to the garage spring professionals.

Electrical Modifications

Is your home's present electrical setup inadequate for your family's needs? Your first instinct as a DIY veteran might be to patch an extra circuit into the system and assume all is well. But it's all too easy to make a simple wiring error that could lead to a devastating fire. A professional electrician can suggest the safest and most effective modifications to create the extra power of functionality you need. These experts are also willing to assume the significant risk of shock that's always present when working with electricity.

Another kind of shock you want to avoid is the potential sticker shock you may encounter if your home does burn down due to an electrical fire. If your insurance company discovers that you tinkered with your electrical system in a away that violated code requirements, your claim may be denied, saddling you with the entire cost of rebuilding.

Working on Old Attics, Walls or Ceilings

If your home was built in the 1970s or earlier, you should treat many ordinary home renovation projects as DDIY jobs until you know whether your home harbors asbestos. Asbestos was a popular building and insulation material before the 1980s. Unfortunately, exposure to the fibers of this naturally-occurring mineral substance can cause serious respiratory diseases, including lung cancer and a cancer of lung lining called mesothelioma. To make matters worse, asbestos wasn't just included as insulation -- it was also an ingredient in floor tiles (and the adhesive backing that held them in place), cement siding, wall and ceiling joist patching compounds, textured paints and acoustical ceiling tiles.

The good news is that asbestos can't harm you unless the particles become airborne. The bad news is that ripping up tiles, sanding away paint, punching through walls into insulated areas and other renovation activities can send dangerous amounts of asbestos into the air. Always have a contractor analyze your older home's building materials to determine whether you can proceed with your various DIY goals.

You can still save lots of money and enjoy the satisfaction of a job well well done of a wide variety of household DIY projects. Just make sure you call the professionals in when they're needed most -- for the sake of your health, safety and property.
