Two Signs Of Poor DIY Asphalt Roof Installation

Posted on: 29 November 2016

Replacing your entire asphalt roof can be an expensive job. For the most basic roof possible, you may spend as much as $9,000 for a professional installation. If you want to save yourself on labor, which is typically about 60% of the cost, you can attempt to install the roof yourself. If you do this and you make a mistake, then you will notice some signs of this soon after the initial replacement. A few common signs of poor DIY installation are outlined below, so look for the mistakes and contact a roofing repair expert for assistance if you notice them.

Buckling Shingles

Buckling shingles are roofing shingles that look like they have vertical wrinkles along the exposed part of the shingle where the tabs sit against the roof. The buckling can occur for several different reasons, but it is often caused by moisture problems. If your old roof was leaking or if you completed your roofing project in the rain, then the wood decking was likely wet when you installed the new shingles. If the decking remains wet, then this can cause a problem with the materials installed over the wood.

The decking will transfer water to the felt underlayment, and this part of the roof will wrinkle in response. These wrinkles will force up the roofing shingles and cause them to wrinkle as well. While most shingles are relatively pliable when they are first installed, they can crack or break if placed under too much stress. Also, wrinkled shingles may warp if they are bent for too long, and they may not sit flat against the roof once they dry out. 

Also, if you needed to replace the sheathing along your roof, then you may have installed the wood too close together. The wood may then buckle and force the shingles upward. 

If you think that moisture is an issue, then you can install a proper roof ventilation system to resolve the problem. Roofing shingles may also need to be replaced, and roofing felt may need to be flattened or replaced as well. Start by installing the ventilation system, and then contact a roofer to evaluate the roofing materials and their need for replacement. 

Loss Of Granules

Almost all asphalt roofing shingles have small rocks attached to them. These rocks are small pieces of ceramic that reflect the UV rays of the sun. This helps to reduce sun damage across the shingles underneath the granules, and it also helps to keep the roof from becoming too hot in the summer. While granules are baked onto the surface of the asphalt shingles, they can come off if you handle the shingles improperly or walk on them during the initial installation. 

If you notice the granules in your gutters or if you can plainly see large areas of the roof where the rocks have already fallen off, then it is wise to replace them. You can replace the granules yourself by purchasing a large bucket of them from your local roofing supplier. They can be adhered with roofing cement. However, you may want to do this only if the granules are a basic white, black, or gray color.

Roofing granules come in a variety of different color options, and different manufacturers will use different color varieties for their shingles. Some companies will even use a variety of different tones to create a more natural roof appearance. If you decide to replace these granules, then you may create an obvious pattern on your roof if you choose the wrong tone. If this is a concern of yours, then contact a roofer from a company like All American Roofing Incorporated who has more experience in asphalt granule differences, tones, and application.
