Silicone roof sealant is also a great option to fill in shingle cracks and leaky nail holes and is also used to repair folded or slightly lifted shingles.
A small, droplet-like amount of silicone will have to be placed with a caulk gun under the bent part of the shingle. You will then have to bend back the affected shingle into its original, proper placement, put weight on it and let the silicone dry. A bent flashing may be repaired in this manner too.
When it comes to separations between the shingles and the flashings or vent or mortar, a small amount of silicon caulk will have to be pushed into it in order to cover the separation.

How Do Roofs Become Damaged How Do Leaks Form
The most common cause of a leaky roof is damage.
However, how do roofs get damaged in the first place? Many elements can damage your roof, but some are more common than others.
For most homeowners, the most common cause of a leaky roof is damaged shingles. Shingles can become damaged from weather, impact damage or improper installation.
In most cases, impact damage is the result of either the homeowner walking on the roof, animals running across it or hail damage. Thats right, the squirrels and other animals that run across the tops of homes can cause damage that leads to leaks.
If homeowners do their research and hire a professional, improper installation typically wont occur. Improper installation usually happens when homeowners try to install their own shingles.
The expanding and contracting of the material eventually causes it to crack. When shingles crack, water can seep into and underneath them. If the water freezes, it expands and further damages the shingles.
Sometimes, roofs leak just because theyre old. Like anything else, roofs eventually break down and need to be replaced. In fact, some roofing materials last longer than others.
For example, asphalt is one of the cheapest roofing materials but has one of the shortest life spans. Metal roofs last much longer but cost more than shingles. Slate roofs can last the longest, sometimes upward of 100 years, but cost the most.
Finding The Source Of Your Roof Leaks
It can be difficult to discover the source of most roof leaks because the spots where you can see the leak are often not particularly close to the leak itself.
After all, water travels downhill from the spot where it enters your roof, so the actual hole or leak could be much higher on the plane of the roof.
For example, roof leaks often travel downline from rafters, sheathing, or the top of the ceiling until theres a spot where the water can drip down and by the time you notice it, it might be a pretty significant leaking roof.
Roofing experts will advise you to think like water when you search for the source of a roof leak know that water typically comes in through broken or overly shingles, missing shingles, poorly sealed or corroded flashing around chimneys, skylights, vents, or along the intersection of different planes, or spots where nails are loose or missing.
If you dont have attic access or have a vaulted ceiling, you may need to go up on the roof or find another way to examine things.
Keep in mind that this can be tricky and you may want to hire professionals for this part if youre unsure of your capabilities.
Finding a professionalroof leak detection company or roofer in your area can also help save time and money.

Fix Plumbing Vent Boots
Plumbing vent boots can be all plastic, plastic and metal, or even two-piece metal units. Check plastic bases for cracks and metal bases for broken seams. Then examine the rubber boot surrounding the pipe. That can be rotted away or torn, allowing water to work its way into the house along the pipe. With any of these problems, you should buy a new vent boot to replace the old one. But if the nails at the base are missing or pulled free and the boot is in good shape, replace them with the rubber-washered screws used for metal roofing systems. You’ll find them at any home center with the rest of the screws. You’ll have to work neighboring shingles free on both sides. If you don’t have extra shingles, be careful when you remove shingles so they can be reused. Use a flat bar to separate the sealant between the layers. Then you’ll be able to drive the flat bar under the nail heads to pop out the nails.
