Identifying The Signs Of Blocked Roof Drains

Overflowing Gutters: If you notice water overflowing from your gutters during rainfall, it's a clear indication that your roof drains may be blocked.
Stagnant Water: Pooled water on your roof or around the base of your home suggests the drainage system is not functioning correctly.
Interior Water Stains: Water stains on your ceilings or walls may signify that water is not properly draining from your roof, potentially due to blocked drains.

Before attempting to clear blocked roof drains, gather the following tools and materials:

Gloves & safety gear
Ladder
Garden hose
Plunger
Bucket & trowel

Step-by-step Guide To Clearing Blocked Roof Drains

Safety First: Before starting any work, ensure you have stable footing on the roof and use appropriate safety precautions.
Inspect the Gutters: Begin by inspecting the gutters for visible debris such as leaves, twigs or dirt. Use a gloved hand or a trowel to remove any blockages.
Use a Garden Hose: With the hose attached to a water source, direct a high-pressure stream of water down the drain. This can help dislodge and flush away smaller debris.
Plunge the Drains: If water isn't flowing freely after using the hose, use a plunger over the drain to create suction and dislodge stubborn blockages.
Check Downspouts: Ensure downspouts are clear by directing water down them with the hose. If water doesn't flow freely, there may be a blockage that needs clearing.
Inspect & Remove Debris: For persistent blockages, inspect the roof drain itself. Remove the drain cover and use a trowel or gloved hand to remove any accumulated debris.
Chemical Drain Cleaners: In some cases, chemical drain cleaners may be used to break down organic material causing blockages. However, exercise caution and follow product instructions carefully.
Professional Assistance: If DIY methods prove ineffective, or if you're uncomfortable working on your roof, it's advisable to seek professional assistance.
Preventive Measures: To minimise the risk of future roof drain blockages, consider implementing the following preventive measures:

Regular Cleaning: Schedule regular gutter and roof drain cleaning, especially during seasons with increased foliage.
Install Gutter Guards: Gutter guards can prevent leaves and debris from entering the gutters, reducing the likelihood of blockages.
Trim Overhanging Trees: Trim branches and foliage that overhang your roof to minimise the accumulation of leaves and debris.
Professional Inspection: Periodic professional inspections can identify potential issues before they escalate, ensuring the proper functioning of your roof drainage system.
