Roof Leak Common Causes

Roof Leak Common Causes

Have you ever gone into the bathroom in the morning to shower and get ready for work? Only to find an ugly brown spot in your bathroom or one of the bedrooms? What about when you go to light a fire in the winter and find water dripping on, or even inside, your fireplace? How about my personal favorite? Water dripping onto you WHILE YOU SLEEP!?! No need to worry. Today we will discuss roof leak common causes and what you can do to remedy the problems.

Leaks in the Bathroom of Kitchen

First, we will discuss a big culprit of roof leak common causes, leaks in the bathroom or kitchen. This type of leak tends to come from one place in particular, your PVC plumbing pipes that protrude through your attic and roof. A rubber flange, with a hole for the pipe to fit through, is secured around the PVC pipe to prevent water from entering around it. Water can enter the inside of the pipe, without any water entry issues. However, if the water enters on the outside of the pipe, due to breaks and cracks in the rubber, it can and usually does cause a significant leak in a home’s kitchen or bathroom. These leaks are due to the fact that most of your plumbing pipes route to these areas.

Leaks Around Chimneys and Flashing Walls

The second roof leak common cause we will discuss is leaks around chimneys and flashing walls. This type of leak tends to show up during heavy rains. You may see water leaking down your drywall on the outside of the chimney, or dripping on the inside. You may see drywall damage and stains where your garage meets the house, the foyer entrance of your house, or along the walls of dormers on the front of the house.

How do you know these things, you might ask? It’s because these intersections on the roof, tend to be where a vertical structure (like a wall or a chimney) require an adequate flashing system to prevent water from leaking into the roof. 75% of the time, the fix is simple… maintenance your roof after it’s initial 8 to 10 years. Caulking dries up and peels off, aluminum flashing gets bent from wind and flying debris, and fasteners (nails & screws) become dislodged due to temperature change and exposure to the elements. However, their are times where the initial installation of the wall flashing system is entirely improper, and prolonged or extensive damaged may be affecting structural items on the roof, like the wood decking it is secured to. In those cases, the flashing system needs to be removed and reinstalled with all the proper components.

Leaks due to Wind Driven Rain

This type of leak is the most unique type of leak and tends to happen during more severe weather events. During a strong storm, rain may be accompanied by wind gusts. These wind gusts blow the shingles up and either break the matting of the shingles, or it bends/creases it, during the storm. Sometimes these leaks are easy to detect, because the missing shingles on the roof make it quite obvious. However, at times, shingles may raise during a wind storm and allow water to enter through a nail hole, or seam where parallel shingles meet. These leaks tend to happen for 1 of 2 reasons.

Types of Causes for Wind Driven Leaks

Improper Installation

First, the most common: improper installation. This means, the people who installed your roof originally did not nail on the shingle where they should have, allowing the shingle to bend during strong winds and either cause a leak, or break completely.

Material Defects

The second reason these leaks tend to happen is due to a material defect, in the shingle. It is common, with certain shingle manufacturers, to have a defect in the production of certain shingle lines, from certain factories. If this occurs within the first 10 years of the roof’s installation, I would recommend you file a claim with the shingle manufacturer for a defect. Otherwise, I would advise you to repair the problem if it is small, and save up for a new roof in the future. Maintenance of your roof goes a long way though folks.
