Pipe boot failure
Check the base of your plumbing vent pipes. Around the pipe, you can see a rubber boot. Often, the leaks are caused by cracks around a plastic base, broken seams on a metal base, or torn or rotten rubber boots. Sometimes, a nail that secured the base to the roof may be loose or missing. Leaks from pipe boot failure are found in rooms with water sources such as bathrooms and kitchens.
Improperly driven nails
Check for nail heads that are sticking up. Roofing or decking nails that are not driven far enough or driven sideways draw out of a shingle. Leaks caused by improperly driven nails can be found wherever the nails are located.
Chimney wear and tear
When leaks are coming from the chimney, there could be several reasons for it. The leaks may be due to problems with the chimney's metal flashing, saturated mortar joints, cracks or rust on the masonry or metal top, or rotting corner boards of the chimney siding. Regardless of the cause, however, this is not a problem that can be fixed by non-professionals. Hiring professionals that provide services for chimney repairing in Virginia Beach is encouraged.
Debris in gutters
The area in the roof where two slopes meet and form a V-shape is called a valley. It allows water to freely flow down the roof. Sometimes, valleys stop in the middle of the roof. A gutter, carried by a board along the lower edge of the roof, is placed to allow water to continue flowing down. The board is called fascia. This gutter in the valley can get filled with leaves and debris. These block the water’s pathway. Therefore, the water flows to parts where there is the least resistance. Under extreme or continuous rain, the water flows down to the underside of the fascia, especially if there is no flashing applied to it.
Improperly installed skylights
When an installer of skylights does not follow the manufacturer’s instructions for installation, these will surely cause leaks. To check if your skylights are correctly installed, check their components or parts. Repairing it usually involves taking the cladding and flashing kit off to put an ice and water shield around it.
