Scrolling through social media, you have probably seen countless videos of homeowners tackling impressive-looking DIY projects. These short clips make complex home improvements seem quick, easy and affordable. But when it comes to your home’s exterior, especially your roofing and siding, some of these “hacks” can cause major damage. Worse yet, they can void your manufacturer’s warranty, leaving you to pay for expensive repairs out of pocket.
Before you try that popular trend you saw online, let’s look at five common DIY disasters that could cost you big time.
1. Pressure Washing Your Roof Shingles
That satisfying video of grime being blasted off an asphalt roof looks great, right? Unfortunately, using a high-pressure washer on your shingles is one of the fastest ways to destroy your roof. The intense stream of water can strip away the protective granules that shield your shingles from UV rays and harsh weather.
Losing these granules exposes the underlying asphalt to the elements, leading to premature aging, cracking and leaks. Most roofing warranties explicitly forbid this practice. If you need to clean your roof, it is best to consult a professional who uses safe, low-pressure methods.
2. Painting Vinyl Siding the Wrong Color
A fresh coat of paint seems like a simple way to boost curb appeal. We have all seen the dramatic before-and-afters of homeowners painting their siding a trendy dark color. The problem is that vinyl siding is not designed to absorb the heat that comes with dark paint colors.
Darker shades attract more sunlight and can cause the vinyl panels to warp, buckle and distort. This damage is often irreversible, and your siding warranty will not cover it. If you want to paint your siding, stick to vinyl-safe paints in colors that are no darker than the original shade. Have you ever wondered if your paint choice could cause this kind of damage?
3. “Patching” a Roof Leak with Caulk or Tar
You spot a small leak, and your first instinct might be to grab a tube of roofing cement or caulk for a quick fix. While this may temporarily stop the water, it is not a permanent solution. These patch jobs often fail quickly and can trap moisture, leading to wood rot and more significant structural issues beneath the surface.
Professional roofers know how to properly identify the source of a leak and make a lasting repair by replacing damaged materials. Relying on a tube of sealant is a risky gamble that manufacturers will not back with a warranty.
4. Improperly Installing Siding or Shingles
Replacing a damaged piece of siding or a single shingle might seem straightforward. But there is a precise technique to it. Nailing siding too tightly can cause it to buckle with temperature changes, while improper nailing on shingles can create entry points for water.
Exterior materials are designed to work as a system. One incorrectly installed component can compromise the entire structure’s ability to protect your home. This is why manufacturers require installation by certified professionals to keep the warranty valid.
5. Covering Old Siding with New Layers
Some DIY guides suggest you can save time and money by simply installing new siding directly over the old layer. This is a huge mistake. Covering old siding can trap hidden moisture and rot, allowing problems to fester unseen.
Furthermore, adding another layer puts extra weight on your home’s structure and can make it difficult to flash windows and doors properly. A professional siding contractor will always remove the old material to inspect the sheathing underneath, ensuring a secure and weather-tight installation.
