You’ve discovered a puddle of water in the corner of a room. Now you’re searching high and low, driving yourself crazy trying to figure out if you have a roof leak. You see ceiling stains and hear a drip, drip, drip. It could be coming from anywhere though! So how do you solve this problem and find the roof leak? At RGB Construction, our team has some tips to help you find the source of the problem. Once you find your issue, give us a call to schedule some roof repairs. We’ll be there as soon as possible.
Key Takeaways
- Roof leaks can originate from damaged shingles, open flashing, dried-out seals, or even hidden punctures.
- Inspecting your attic with proper lighting is one of the best ways to trace leaks back to their source.
- Insulation often conceals leaks but will usually show signs of deterioration, helping narrow down the problem area.
- Objects like vents, chimneys, and skylights are common leak points if seals wear out over time.
- The garden hose test can simulate rainfall and help pinpoint hidden leaks when paired with attic observation.
Causes of Roof Leaks
A leak can be caused several different ways. Due to damages from UV exposure, strong storms, and general wear and tear, spaces can open between flashing, particularly around venting and chimneys. Nails can pop out of storm-damaged shingles, allowing for water intrusion. Branches and other debris hitting your roof can also cause punctures.
Do a quick visual scan of your roof to see if any of the following is happening:
- Curling, cracked, or missing shingles
- Loose flashing
- Damaged fascia
- Detached or clogged gutters
Any of these issues can allow for water intrusion, which will eventually lead to roof leaks.
How to Find a Roof Leak in Your South Jersey Home
There are a few steps to take that could help you solve any leak crisis. It’s time to investigate your home. Here are several places to check when you suspect a roof leak, as well as what to do in each location:
Roof Leaks in the Attic
Find a good flashlight or other lighting device that is easily handled or can be placed around your head or neck, and make your way to the attic. Watch your step, especially if there are is no flooring and you have to step from the joists to explore areas of the attic for leaks.
Using the flashlight, look at the roof’s underside and determine if any section or area of it is darker than the roof’s sheathing. If there has been insufficient moisture over time, it might be difficult to discover any wet spots other than mold, as it will persist. If you do find mold, the chances are you may have encountered a “leaking” point.
If you can’t find any recent areas of moisture, wet the roof ahead of time with a hose to help discover any undetected leaks. Reexamine the rafters and decking to determine if there are any wet spots. Continue to follow along where there might be any developing wet areas from the rafters or roof sheathing on up to the highest spot.
Insulation
Insulation can conceal the under area of a roof and make it difficult to locate a leak, but if there is a leak, the insulation will likely show damage or deterioration. If there is damage, the leak may be a number of feet away from the actual spot on the insulation, so it is best to clear away any insulation that is close to the area. Once it is removed, it is easier to locate the water trail from the area of damage to wherever the water has entered through the roof. If you are working with insulation, it is important to wear protective clothing and gloves to prevent direct contact with skin.
Detecting Roof Leaks with a Garden Hose
If you’re having trouble finding the roof leak using the previous methods, use a garden hose. This is best done with two people. Have someone get on the roof and wash it down with a garden hose. Someone else will need to go inside to look for signs of water intrusion throughout the home.
