Learning How To Tell if Your Roof Drainage System Isn’t Working Properly
Ensuring your property is equipped with a functional roof drainage system is an excellent way to avoid costly repairs from mold growth and other forms of water damage that Portland, Oregon’s rain-heavy weather can spur. Learning how to identify the warning signs of improper roof drainage can help you address issues before they escalate, minimizing the risk of encountering extensive structural and roof-related problems.
If you notice unusual happenings, such as water collecting atop your house or gutters overflowing after rainfall, a professional roofing specialist should inspect your roof drainage system as soon as possible. After surveying issues like damaged shingles or mold and mildew growth around your roofline, well-trained roofing contractors can address underlying problems by performing as-needed repairs.
After learning how clogged or poorly designed gutters affect your roof, contact a trusted roofing company with substantial experience working on roof drainage systems to guarantee that your property is equipped to handle environmental stressors like snow and heavy rain.
What Is a Roof Drainage System?
A roof drainage system is a combination of roofing components that divert water and debris safely from your home, starting with the various slopes throughout your roof. Some examples of other parts that can make up roof drainage systems are:
- Gutters, including K-style, half-round, and box gutters
- End caps for gutters
- Leaf screens or solid covers for gutters
- Drop outlets
- Elbows for drainage
- Downspouts
- Splash block
- Fastening parts, such as straps and bracket hangers
By ensuring each part of your roof drainage system is functioning well, you can protect your roof, siding, and home’s foundation from damage that can arise from falling debris or heavy rain, which is especially common in the Pacific Northwest. Schedule top-of-the-line gutter cleaning services in Portland, regular inspections, and as-needed maintenance to prevent blockages or leaks and encourage long-term performance from your roof drainage system.
Warning Signs to Look for on Your Roof Drainage System
If any of the following seven circumstances apply to your property, be sure to have a trusted professional roofing company like Roof Life of Oregon address the issues immediately.
1. Water Pooling on the Roof
When a roof drainage system fails to expel water properly, it can lead to a prolonged moisture presence that puts undue stress on your roof. Some of the primary reasons water pools atop a roof are:
- Blocked drains
- Poorly designed slopes
- Damaged roofing membranes
If left unchecked, stagnant water can weaken your roofing materials and cause premature deterioration. The weight of standing water can damage the outside of your home and cause your roof decking to sag. At the same time, the moisture can seep into vulnerable areas like lifted shingles and increase the likelihood of leaks infiltrating the interior of your home and demanding costly repairs to ceilings, walls, and insulation.
If you notice puddles atop your roof while surveying your property, take immediate action by having a reliable roofing professional improve drainage and correct slope issues. Doing so can preserve your roof’s integrity and avoid further damage.
2. Sagging or Overflowing Gutters
Blockages in gutters or downspouts can cause roof drainage systems to overflow during rain since water cannot be discharged through the traditional pathway. In extreme scenarios, the weight from water and debris can cause clogged gutters to warp and bow downward. You should keep an eye out for water spilling over the side of your gutters and have your roof drainage system professionally cleaned on a regular basis to catch this issue before it worsens.
Some of the most common items that clog gutters and lead to overflowing or sagging are:
- Leaves or pine needles
- Twigs, seeds, or flowers
- Dirt or sediment
- Trash like lightweight wrappers or plastic bags
- Animal nests
- Toys like balls
- Ice and snow
In addition to the list above, deteriorating shingles can contribute to blockages in your roof drainage system. Natural wear and severe weather conditions are some of the most noteworthy reasons why there are roof granules in your gutters, impeding roof drainage.
3. Water Stains on Ceilings or Walls
If you are trying to catch roof drainage problems early, routinely inspecting your home’s interior is just as important as surveying the outside of your property. As you walk through your home, you should look for discolored spots on the walls or ceilings. Water stains on the ceiling can be caused by leaks near roof edges or poorly sealed drainage components. Moreover, gutters on dormers can cause leaks on your roof that can contribute to staining and water damage throughout your home.
If a trained roofer does not address water stains promptly, it can lead to more severe problems, such as peeling paint or compromising insulation. Compromised insulation has the potential to reduce your home’s energy efficiency and create an ideal environment for mold growth. Mold growing on building materials like insulation can lead to health complications for anyone inhabiting the property, increasing their risk of developing respiratory issues or headaches.
4. Growth of Mold or Mildew Near the Roofline
As mentioned above, checking materials like insulation to prevent mold from growing in your attic and the interior of your home is essential. Still, it is important to know that mold and mildew can also grow on the outside of your home. If your roof drainage system is not working properly, persistent moisture can cause dark and fuzzy fungal patches to grow near your gutters or fascia boards. Sometimes mold, moss, or algae may manifest as green gutter slime on your roof, hindering your home’s aesthetic appeal. If provided a shaded, moist environment with organic material to feed on, mold can quickly spread and grow onto other building materials.
Children, elderly people, and immunocompromised individuals are exceptionally vulnerable to health risks from mold and mildew; however, anyone can be affected. Some examples of health risks that prolonged mold exposure can present are:
- Respiratory problems, including coughing, wheezing, and shortness of breath
- Allergic reactions, such as sneezing, runny nose, itchy eyes, and skin rashes
- Asthma attacks or flare-ups
- Chronic sinusitis
- Headaches
- Fatigue
To avoid health issues amongst residents and long-term damage to roofing materials, improve drainage and treat mold growth promptly.
5. Pest Infestations Around the Roof or Gutters
Moisture doesn’t just fuel fungal growth. Standing water from your roof drainage system can serve as an ideal breeding ground for pests as well. Suppose you witness an increased presence of mosquitoes or rodents on your property, particularly near your roof. In that case, you need a qualified professional to eliminate the standing water and seal gaps in the roofline.
If you do not take preventative measures and address the conditions that have encouraged the proliferation of pests, the creatures may damage roofing materials or find ways into your home.
6. Visible Damage to Shingles or Roofing Materials
Sometimes, prolonged exposure to poorly drained areas on your roof can cause damage to your roofing materials. Pay attention to shingles that are warped, curled, or cracked, and get them replaced as soon as possible. If left untreated, asphalt shingles that have lifted up or split can create pathways for water intrusion, potentially accelerating the deterioration of your roof or causing leaks that endanger the interior of your home.
A reliable roofing professional can help you keep gutters clean and prevent water from backing up onto the shingles. They can also repair chimneys and replace skylights to avoid leaks and ensure all of your roof’s components work harmoniously.
7. Foundation Damage or Soil Erosion Near the Building’s Perimeter
Ineffective downspouts or clogged drainage systems can erode the soil surrounding your building and ultimately damage your foundation. Some signs of foundation damage are:
- Cracks in the foundation or exterior walls
- Cracks in the ceiling or interior walls
- Uneven floors
- Misalignment of doors or windows
- Gaps between walls and ceilings
- Pooling water near the foundation of your building
- A tilted chimney
To avoid compromising the structural integrity of your house, look out for soil erosion patterns, including exposed roots, bare patches, or washed-away soil near your home’s base, especially after heavy rain. If early detection is prioritized, a professional can install or extend downspouts to redirect water away from the foundation and prevent further damage.
Although routinely walking around and inside your house can help you catch certain issues related to your roof drainage system, hiring an experienced roofing contractor for inspections and repairs is the best way to catch roofing issues in their early stages.
