Architectural Roof Shingles

Architectural roofing shingles are specialized asphalt shingles which can give a three dimensional look to the roof. These high-end shingles are otherwise known as laminated or three-dimensional roof shingles. Asphalt shingles, which were introduced during the 1950s, consisted of flat asphalt-saturated cellulose or fiberglass mats with mineral granules coating. The efforts of the manufacturers in improving the quality and texture of these shingles resulted in the creation of a forerunner of architectural roof shingles, which was introduced in the 1970s.

This new type of asphalt shingle had a heavier mat base, as compared to the earlier version. The mat base consisted of fiberglass or some organic material and asphalt. The back of these shingles were coated with a special material and the top layer was covered with colored granules to create a shadow pattern. Consistent research resulted in many new types of architectural roof shingles in various colors, patterns and textures. Some of these patterns can imitate the looks of cedar shakes, slate or tiles. This new entrant has revolutionized the market of roofing materials, and has emerged as a preferred one for roofing new constructions or for replacing old ones.

How are Architectural Shingles Beneficial

One of the main reasons behind its popularity is the durability of architectural roofing shingles. Usually, they come with a warranty period and some types have a warranty of forty years. They are heavier than other types of roof shingles and hence offer more protection to the roof structure. It is also observed that architectural shingles are easy to install. Most types of these shingles are algae resistant, fire-proof, and can withstand extreme temperatures, and events like strong winds. These shingles require less maintenance than other roofing materials as well. Apart from the point of durability, the popularity of architectural roof shingles are also attributed to the variety of styles and patterns they offer. Even though these shingles are a little more expensive than other roof shingles, they are worth the price, as they offers many benefits.

How to Use Architectural Shingles

Architectural shingles are best suited for roofs with a slope of 2" per foot or more. If the slope is 2" to 4" per foot, then an additional underlay is necessary to prevent seepage of water, which can result in damage to the roof structure. If there is a possibility of accumulation of water along the eaves, due to icing, a waterproofing layer below the shingles will need to be installed as well. For houses located in areas with a moist climate, the algae resistant variety of architectural roofing shingles helps prevent algae and mildew growth on the roof.

Repair and Replacing Roof Shingles

Roof shingles can be replaced, if damaged and are causing harm to the roof structure. In case of damage to a few shingles, the better option will be to repair or replace them. If the whole roofing needs to be replaced, then one can either retain the existing one and install the new one over the former. This acts as an extra insulation and is also beneficial in saving the expenses of removal and disposal. However, the damaged shingles in the existing roofing should be replaced before the installation of the new shingles. A layer of 30-pound roofing felt should be fixed over the existing roofing, on which the new roofing shingles can be laid. Make sure it is legal to have more than one layer of roofing, according to the local laws. The whole roofing can be removed and installation of the new one can be started from the beginning as well. If the existing roofing is severely damaged, reroofing is always recommended.

However, architectural roof shingles can be used as a new installation or as a replacement. It is beneficial either way, as it is durable, and at the same time enhances the appearance of your house.
