How do you know when your roof needs to be redone?

Don't ignore these seven warning signs that it's time to replace your roof, water damage upstairs or attic. The roof has survived its useful life. Moss, mold or mildew have taken over. Missing flashings, gutter protectors or fascia.

Check your home improvement records to see how long ago the roof was replaced or remodeled. Knowing when a roof was installed (and what it is made of) gives an idea of how much life it has left. For example, a typical asphalt shingle roof lasts 20-25 years, while a roof installed over an existing layer of shingles must be replaced after 20 years. Just because you have some damaged shingles or a little leakage, don't automatically assume that you need a completely new roof.

If your roof has been installed correctly and you are less than 15 or 20 years old, you may be able to get by with repairs rather than a complete replacement. If in doubt, contact a licensed roofing contractor for a professional opinion. Overlapping is when a new layer of shingles is installed on top of the old one. It may be 25% less expensive than a total roof replacement and give your house a new look, but it's usually better to tear off the old roof and start over.

Flashing is a type of roofing material that makes a tight seal around the chimney or other penetrations. Usually made of aluminum or steel, flashing can last 30 years. But if it rusts or cracks, water can leak into the chimney and into the hearth. A local roof inspector can tell you if flashing needs to be fixed.

One of the first things to consider before starting to inspect the ceiling for cracks, breaks and other problems is its age. A roof that is 25 to 30 years old or older may require a complete replacement, even if the roof itself appears to be in good condition to the naked eye. Shingles will have to be replaced if there are cracks. The extent of replacement depends on how quickly the problem is detected, so vigilance remains important.

Learn more about a leaky roof and what to do. The problem with a wind-damaged roof is that exposed spots on the roof can be difficult to detect, especially if the shingles have been lifted. A shingle that has been lifted due to winds may have loosened the sealant and possibly the nail, which means replacing the roof. Learn these tips for removing shingles so you don't have a bed of nails on the ground.

Exposed nails can rust and cause roof leaks. Depending on how many nails are exposed and how long they have been exposed, the roof may need to be replaced. According to our experience, most old-style asphalt roofs begin to fail after 14 years. If your roof is between 18 and 20 years old, then you have achieved a good amount of life with it.

It's probably time to replace it. For example, if one contractor says they need a complete roof replacement, but three others say they just need repairs, then chances are your roof just needs repairs. When inspecting your roof and any new growths you have detected, be sure to do so by inspecting both the inside and outside of your roof. If there are a lot of nails exposed, contractors or the roofing company you worked with in the past may have done a poor job of ensuring the quality and durability of your roof.

If your roof has areas that sink or leak moisture, there is a good chance that the roof is rotting. Another way to determine if it's time to replace or repair your old roof is to take a look at the roofs that surround it. Please note that when your roof is not properly ventilated or properly installed, the manufacturer's warranty on roofing materials will be void. Ask your roofing professional if you notice any hail damage, as it might be worthwhile to open a claim for roof replacement coverage, Feller says.

This is how your contractor will build your roof again after knocking it down to the 3⁄8-inch plywood siding or roof covering. However, there are cases when the roof fails prematurely and leads to a roof replacement long before you need it. Ripping out an old roof offers an opportunity for your roofing contractor to add one of these upgrades. However, in most cases, it is highly recommended to replace an entire roof when a person discovers that the roof is rotten or soaked with water.

Often, there is old, hardened putty where the two pieces overlap in the inner corner, but this fixing of the ceiling does not mean a complete replacement of the ceiling, perhaps a point fastening at best. If you're not sure if you'll need a new roof or if you can simply repair and replace the problem at hand, be sure to check with a professional roofing company or contractor you can trust. If you live in an area prone to high winds and strong storms, the roof of your home may require more attention or reinforcement, depending on the type of roof you currently have installed. A long-time neighbor is likely to give you valuable information about when your roof was last replaced and whether or not it was installed as new or about a previously installed roof configuration.
