Denver Roof Repair Experts Explain 5 Signs of a Bad Roof Installation

February 21, 2018

When you buy a home, you’re buying the entire structure. This means everything from the siding and windows to the roof and foundation are your responsibility to care for and maintain. While you may be a responsible homeowner, there’s no way to guarantee that the previous owner was as meticulous as you plan to be. The contractors they hired to maintain the house may not have done the best quality work. When it comes to your roof, quality workmanship can make all the difference between a leak-free home and major structural damage. Your local Denver roofers share a few signs to watch for when shopping for a house that may indicate a poorly done roof installation.

Missing Shingles

If you’ve noticed missing shingles on your roof, there’s a good chance they were improperly installed. When an experienced roofing company handles the installation, shingles are properly nailed down, making it incredibly difficult for wind, rain, and weather to displace them. However, if shingles are not properly nailed down, they can become dislodged easily. Without the shingles in place, your home is at an increased risk for leaks and water damage.

Sagging Roofline

Properly-built rooflines are supposed to sit parallel with your home’s foundation. This ensures that all supports are adequately holding up the weight of the roofing materials and properly funneling water away from the attic space. If the roofline is sagging, the roof may have been installed improperly or has existing water damage that’s compromising the structure.   

Bulging Siding

The roof and siding may be two separate materials, but they work together to keep the structure safe from water damage. If the roof is not properly installed, water often flows from the roof in between the siding and the wall of the house. While difficult to spot in early stages, it’s easy to find once the damage is fairly extensive. Look for siding that’s bulging or has paint peeling from the material. This is often an indication that water has soaked into the siding and should be a red flag when viewing a home.

Missing Flashing

Flashing is a protective layer of metal that covers the joints on the roof. Though flashing is applied around skylights, roof vents, and any other protrusions, it’s most easily viewed around the chimney. If you notice a buildup of rust on the flashing or the flashing is missing entirely, there’s a good chance the roof has water damage. When properly installed, flashing will sit flush against the joints without moving or trapping water between it and the roof material. When water gets trapped beneath the flashing, it can warp the roofing material, causing the metal to loosen.

Visible Mold or Mildew on the Roof

When water gets trapped in the roofing materials, it can lead to mold and mildew growth both on the roofing substrate as well as the roof’s exterior. Though mold can be cleaned off of shingles relatively easily, it doesn’t grow easily in Colorado. When touring a home, take a look at the roof and search for signs of mold and green or red patches of mildew and algae growing on the shingles. If you see any, there’s a good chance that the roof was installed incorrectly.
