Get To Know The Different Parts Of Your Roof

Do You Have a Reliable Local Anne Arundel County Roofer?

In Anne Arundel County, Maryland, it is important to consider the different components of your roof. We experience the four seasons in Maryland, which causes expansion and contraction on your roof material. This blog article will explore the different aspects of a typical roof with a Pasadena roofing service, whether it is a three-tab system with conventional underlayment or a premier architectural shingle roofing system in Anne Arundel County, Maryland.


In Maryland, the most typical type of roof is a three-tab or architectural shingle. These are asphaltic shingles that have a life span of 30+ years now (depending upon the option you choose) and come with warranties.

3-tab shingles are named for the “cut” of the shingle. The strips have three cuts that give a flat appearance when laid on the roof. These have been around a long time and can be seen throughout Pasadena, Maryland’s community. It is a common roofing material that is still used today but has less of a lifespan than the more aesthetically pleasing architectural shingles, also known as dimensional shingles.

Architectural shingles, also known as dimensional shingles, are the most common throughout Anne Arundel County (new construction). These products are composed of two or more asphalt layers, fused for a thick, varied look. In our opinion, they are the most visually appealing roofing option available on the market for homeowners in Pasadena, Maryland, and throughout Anne Arundel County, Maryland.

Luxury shingle systems are available as well. These options vary, but a common one seen in the local area in AAC and Baltimore County, Maryland, are synthetic slate systems.

Underlayment and Decking

When we install roofs, our roofers in Pasadena keep in mind the pitch and overall construction of your home. The underlayment and decking encompass the components below the shingles, which are supportive and another protective barrier between the elements and your home.

Underlayment options are varied but often asphalt and felt paper materials are used as another moisture barrier and protective sealant when installing shingled roofs. The valleys of roofs (where two portions of the roof meet in a low point) are usually sealed with an adhesive asphaltic underlayment, often referred to as weather guard.

The decking on a home is often 4×8 plywood. Each house can have different dimensions of thickness, depending upon how it was originally built. When installing a new shingle system, we inspect the decking for any damage, often caused by moisture and leaking of the previous system. The best course of action is to remove (by way of cutting out) any damaged plywood and replacing it with new material.

Insulation and Support

These systems are below the shingles, underlayment, and decking. The insulation and support are “inside” of the home and are referred to as the truss system or “bones” of the home (which can also be systems other than trusses) and the insulation to provide an R-value barrier against the cold and heat. Remember, in Maryland, the weather changes constantly, and an appropriate R-value of insulation is essential to maintain a healthy home and not stress out the other systems, such as the HVAC.

We often inspect the attic area, if available, to see any damage from underneath the shingle system. The decking is readily visible, and the insulation and support system. As a professional roofing contractor in Bel Air, we encourage homeowners to inspect their attics if it is safe for them to do so, at least once a year to spot leaks and issues before they grow into anything more serious.

Gutter System

The gutter system is to collect the water and get it away from the home’s foundation. In Pasadena, Maryland, we often see water issues in people’s basement due to improper gutter installation and clogged gutters. Remember, the point of having the gutter is to get the water away from your home so that it doesn’t saturate the area and eventually get into the home. A proper gutter system combines the roof’s protective layer with an escape route for the water. Once you’ve installed an adequate gutter system in Pasadena, MD then you should consider annual maintenance such as cleaning and inspection. Over time, water can do a lot of damage to a home, and the solutions are often based on remembering a simple principle: water flows downhill. Ensure the foundation of your home, where the soil or substrate meets the home, is sloped away from the home. This will help make sure water flows from the roof, into the gutter, through the downspout, across the properly graded yard, and to an eventual drainage system or body of water.
