A roof’s deterioration is caused by exposure to the elements over time. Roofing materials are weakened by strong winds, intense heat, and heavy rains. In other words, repairs or replacements may be necessary at some point with these materials. As soon as you discover a roofing issue, you ought to act quickly to repair the damage and protect your home from these weather conditions.

Beware, however, as inexperienced contractors can make the problem worse, causing bigger problems down the line that are much more costly to fix. The following roofing mistakes should be avoided by every homeowner in order to keep their home protected and in good condition:


Mismatched shingles are more challenging than you think. When repairing your roof, you don’t want the shingles to look mismatched, making your roof look unkempt. There will be a patchwork quilt for everyone to see and discuss at the next BBQ. In the event that you are planning on reselling your home, this would be a definite deal breaker. A hole patched with brand new shingles will stand out even more when weathering discolors the shingles. You can rely on Greenman Roofing to find an exact match for your shingles so your roof will be seamless. You can trust us to assist you in choosing the right roofing materials and shingles that will last for many years.


It is important to use high-quality materials in everything you do. Therefore, the flashing on your roof should be replaced instead of using the old stuff. By failing to do so, your flashing will be distorted, and it will become damaged much faster than new flashing.

Recycling old material may seem like a good idea, but the truth is that it’s not worth the effort. In a few short weeks, your new roof repair will leak, and you’ll wish you’d used a new one instead.


Getting a roof permit ensures that your roof is safe for you and follows local building codes. Most areas require a permit to install a new roof. In some cases, unscrupulous contractors might begin work without obtaining a permit. This could put the project on hold until the permit is obtained. Hiring a professional and licensed roofing contractor will ensure that your roofing project runs smoothly.


A drip edge is a piece of aluminum installed on the edge of a roof. Their job is to redirect water away from the wall of your home and into the eaves. A drip edge prevents water from collecting under your shingles, which can cause damage to your house. Many older houses don’t have a drip edge installed, but it is a requirement in most current building codes. Furthermore, drip edges prevent wind-driven rain from entering your roof.


The most common roofing mistake is to apply your new roofing directly to the wooden deck of your roof. After the existing shingles or tiles have been removed, an underlayment should be applied before adding new materials.

A roofing underlayment adds a water-resistant layer on top of which the rest of your roof can be installed. Moreover, protecting your home and roof with this layer helps you have a longer-lasting roof.


Shingle alignment is one of the easiest ways to identify a poor roofing job. If the shingles don’t have vertical cutouts, or if the joins aren’t parallel, the shingles are misaligned. Visually, this can make your roof look sloppy, but it also poses a problem in terms of coverage and protection. Roofing shingles that are misaligned create cracks and gaps, allowing water to enter your roof, roof deck, and home.


Don’t forget about your attic when putting a new roof on. The last thing you’ll have to worry about is your roof if you don’t consider the attic underneath your roof. If you neglect your attic, you may cause structural failures in your home and compromise its structural integrity. Make sure you inspect your attic before you begin.


When your roof is covered in asphalt shingles, repairing a leak is a simple matter of locating it and sealing it. Water damage is one of the most common problems for roofs. This can slowly degrade your home’s interior and structure. We are highly trained to fix a leaky roof.

A leaky roof can be fixed in the following ways:


The leak will most likely be evident by water stains on the ceiling. There is a possibility of leaks at any point where the shingles meet. Finding roof leaks can be a frustrating task for many.

As water is pulled by gravity it’s best to use a process of elimination first. This may not be such an easy task as water can transfer from one area to another as it runs downward to its ultimate entry point inside your home. That’s why you need a professional roofer to find and fix the leak properly.


Over time, the cumulative effects of sunlight, moisture and changes in temperature can cause roofing shingles to curl or cup. It may be time to replace your roof when the shingles start shrinking up and curling as they approach the end of their useful life.

This can, however, also be the result of improperly installed shingles. It appears that there are ventilation issues where trapped moisture has curled the shingles. A phenomenon known as thermal shock is one of the main reasons for shingles curling. You can put your trust in our technically sound experts for all of your these types of problems.


Greenman Roofing can easily be repaired if there are small holes in the flashing. Pinholes should be filled with roofing cement, and larger holes should be patched with the same material as the flashing.

Before we clean the hole, we roughen the area around it with a wire brush or sandpaper. Cut the patch larger than the hole, affix it with roofing cement, and then cover it with more roofing cement, as shown at right.


Using a tarp to repair a roof leak in San Jose is a simple and quick solution. Now that you’ve located the point where water is entering the roof, we can cover it with a tarp.

By keeping moisture out of the affected area, a tarp protects the area. We’ll want to ensure that the tarp is draped over the point of your roof in order to achieve the best results. As a result, water will not be able to run under the tarp.


Greenman Roofing can repair roof leaks using roofing cement to patch cracks, patch holes, and make other repairs. Roofing cement can also be purchased from a hardware store or online. Using this technique is most effective on a dry roof.

Roof cement is an easy material to apply. The only thing we need to do is remove debris from the hole or crack, and then fill it with roofing cement. In lieu of cement, our roofers prefer using roofing mesh to keep it secure.


If you need to repair shingles on your roof but don’t have extra supplies lying around, we can create a temporary shingle from sheet metal or sheeting. Using sheet metal cut to the same size and shape as a shingle, we can repair it like an ordinary shingle.
