A roof leak is concerning because the leaking water can do a lot of damage to your home. However, when you notice a water stain on your ceiling, your first response might be to wonder where the rain is coming from.
A roof leak isn't always right above a water stain because water can roll a long way before it drips through the roof and on your ceiling below. You may need help from a roofing contractor to find the leak and then repair it. Here are three likely places to start looking for a roof leak.
1. Around Things That Protrude Through The Deck
Anything that penetrates the deck or shingles creates the potential for a leak. This includes the chimney, skylights, solar tubes, plumbing vents, and even solar panels. These things are often sealed with metal flashing, rubber boots, and adhesives that wear down as they age due to sun exposure and rain.
One thing to keep in mind is that old flashing that's rusted and worn out could indicate the rest of your roof is old too. The roof leak could be a warning sign that you'll need a new roof in a few years.
2. In The Roof Valleys
The rain rolls down the slope of your roof and in a valley. Since so much rain is concentrated in the valley, it can be prone to leaking. Leaves and debris often get stuck in valleys too, and the leaves hold moisture against the shingles and cause the roof to age faster and be more prone to leaking.
Valleys have flashing in them to protect the roof from leaking, and the metal flashing can rust and cause a roof leak. Water might enter a rusted hole and continue to roll down the deck and make it difficult to pinpoint the source of the leak.
3. Near Damaged Roofing Shingles
If you notice shingles that are cracked, broken off, or dented, the damaged areas could be the source of your roof leak. When bad shingles are the problem, you should consider the age of your roof and the condition of the roofing.
Sometimes, it is a better use of your money to have a new roof installed rather than invest in repairs. Your roofing contractor can offer advice when you're trying to decide between a roof replacement and roofing repairs.
You may not know the full extent of the problem until a roofer has examined the shingles and deck. A roof leak might not look too bad on the surface, but there might be extensive water damage to the deck that also has to be repaired when new shingles are put on.
