What is a leaking roof? 

There is probably a leaking roof to blame for water stains that extend across ceilings or run down walls. The hard part is finding the leak, but repairing it is usually not difficult. We will teach you some simple tricks on how to find and fix most of the common types of leaky roofs. You can read the most common causes of rook leaks here.

1. How to find a leaking roof 

You should start by scanning the roof uphill from the stain if you’re looking for a leak. Your first step should be to check for roof penetrations. Almost all leaks originate from items that penetrate the roof. There are rarely leaks in open areas of unbroken shingles, even on older roofs. For example, types of penetrations include; chimneys, roof vents, dormers or anything that projects through the roofing. If your house has access to an attic, it will be relatively easy to examine the leaking. You’ll have to climb up to the roof and examine it further if access is difficult or you have a vaulted ceiling. Find out more here on the right diagnosis and repair for a leaking roof.

2. How to repair roof vents 

Ensure that the plastic roof vents are not cracked and the metal ones are not broken. Caulk might seem like an easy fix, but it isn’t going to last long. Ideally, you should replace the damaged vents. You should also check the base’s bottom edge for missing or pulled nails. If necessary, replace them with rubber-washered screws.

3. Complex roof leaking problems during winter storms 

A lot of roofs leak during the storm and winter seasons due to poor flashing. Waterproofing the area of the roof where the soffit meets the roof can be a challenge. Eventually, the water can freeze up when it touches the colder edges of your roof. After some time, water pools behind the dam and runs back up under the shingles and down under the soffit until it finds a way through the roof. You can fix this by using good flashing since this should help prevent leaks from rain and perhaps ice dams as well. 

4. Do not use Caulk! 

You should always try to fix a leaky roof mechanically when possible, rather than sealing it with caulk or roof cement. This means replacing or repairing existing flashing in place of using any type of sealant.
