Roofing Accessories & Flashings

Roofing Accessories

A roof is more than just the shingles you see on the outside. To keep your roof looking beautiful and free from damage, you will want protection with the high-quality roofing accessories that are essential for a leak-free roof. If water is left to collect and pool on your roof, it will be forced to drain from the nearest hole or crack. This could very well allow water to seep into your ceiling,  walls or foundation. In the colder months, this is particularly risky because if ponding water freezes, it will expand and can break up the roof’s surface, creating cracks for melted water to penetrate. Unfortunately, once this happens, you can’t turn back time, and it must be repaired. 

Protection From Water
There are many steps to a roofing project that not only keep your roof looking great but help it last longer. One of the main issues we work to combat is water damage. Once water seeps into your home, it is difficult to correct, so we prefer to prevent the problem before it even starts. To do so, we apply a leak barrier, underlayment roof protectant, and starter strip shingles to all of our roofs to keep them protected from water and ice. It is also crucial to have quality gutters and flashings to keep water moving off your roof.
Leak Barrier
To help protect your roof from water damage, we install a leak barrier. This fiberglass-reinforced material is used in multiple areas on the roof of your home or commercial building. These are generally placed along areas that are most likely to develop a leak such as the eaves, valleys, around chimneys, and at rakes. This can help you save money long-term by having an additional barrier against water and ice that can cause severe damage to your roof. Additionally, some building codes require the installation of leak barriers, especially in areas where temperatures can dip below 25 degrees Fahrenheit in the cold winter months.
Underlayment Roof Protectant
Roofing underlayment is a layer added to the entire surface of your roof to protect against water damage when severe weather comes, and the top layer of shingles can become compromised. It is a waterproof or water-resistant material that creates a barrier between your roof deck and everything on top of it. The three main types of underlayment are rubberized asphalt, synthetic underlayment, and asphalt-saturated felt. This layer becomes crucial when severe weather hits and wind or hail lifts or tears shingles off the roof. It provides an additional layer to keep water from getting to the inside of your home and causing further damage.
Starter Strip Shingles
Starter strip shingles are the first layer of shingles applied to a roof. Generally, they are used at the lower eave edge, the gable, or rake edges of a roof. They are applied before the finishing shingles to guarantee complete coverage. Starter shingles are useful for protecting joints in the roof as well as creating an overall line of defense against the wind. When appropriately positioned, the strip of sealant on the edge of the starter shingle should line up with the rake ends of the finishing shingles. When warmed by the sun, the bottom starter shingles should create a seal with the top finishing shingles, making it much harder for wind-blown rain to get under the finishing shingles.
The gutter system on your roof is designed to move water away from your roof quickly. The less time water spends on your roof, the better. They help limit the damage to your roof and home caused by rainfall. Without a proper gutter system, rain will fall from your roof onto the ground directly below, creating big, muddy puddles and over time can seep down deep near the foundation. This leads to a whole mess of problems like erosion and cracks in the foundation. Keeping your gutters clean and functional is highly essential to the protection of your roof and shingles. If water fills the gutters and sits at the edge of the roof, it can cause damage to those areas.

Types of Flashings

Chimney Flashing:

As the name implies, this flashing is applied around the base of a chimney along the bottom, sides, and at the top. 

Continuous Flashing:

This adds protection to the joint where the sloped roof meets a vertical wall. 

Drip Edges:

These are applied along the eaves underneath the roofing felt as well as along the rakes, over the roofing felt. 

Step Flashing:

Consisting of a series of right-angled metal pieces, this flashing protects the areas where the roof meets a chimney, the side wall of dormers, and some skylights. 

Valley Flashing:

This is a W-shaped channel placed on top of the roofing felt where two roof planes meet. The roof’s finishing shingles are then applied over it.

Choosing the Right Commercial Roof Materials

There are many decisions to make when planning for roof construction on a new building, one of them being the material used. You will want to choose your commercial roofing material based on your needs, budget, and the look you desire. Below are some of the options we offer.

Asphalt Shingles

A very commonly used roofing material, asphalt shingles are easy to produce, making them a very affordable option. They come in various styles and color and last between 15 and 30 years.

Concrete Tile

Concrete tiles are made from sand, cement, and water, and come in a wide variety of sizes, shapes, colors, and textures. The lifespan of concrete tiles ranges from 40-60 years given proper maintenance.

Metal Roofs

Metal roofing is one of the best long term options that has a life expectancy of 50 years or more. You can choose from a variety of metal types such as copper, stainless steel, and aluminum.


This roofing material is thermoplastic, single-ply membrane, and forms a powerful, watertight bond when the seams are heat-welded. Installation methods typically include fasteners, full adhesion and heat welding. PVC last between  25-35 years.

Modified Bitumen

Polymer-modified bitumen or modified bitumen (MB) sheet membranes are composed of many layers. They are generally fully adhered and installed as a two-ply roofing system. The two types of MB roofing membranes are APP polymer-modified bitumen and SBS polymer-modified bitumen. The average lifespan is 15-25 years.

Wood shake Shingles

This type of shingle is made from redwood, pine, red cedar, or cypress trees. They have a life expectancy of 20-60 years depending on the type of wood and climate.

Synthetic Composite Shingles

These shingles use the most advanced materials to build shingles that look like traditional designs but offer improved weathering and hail resistant characteristics.


EPDM is quick, clean, and inexpensive. It is a single-ply membrane that is typically applied with fasteners, adhesives and possibly balast. Highly resistant to water and heat, this synthetic rubber roofing material an excellent option for flat roofs it should last 20-35 years.


This thermoplastic, single-ply material is reinforced and offers a more durable flat roof solution than previous materials and comes highly recommended for the flat roofs of commercial buildings. Sheets of TPO are welded together with heat, creating an impenetrable surface. This material performs well at protecting your building from the elements and most chemicals. TPO has a life span of 20 to 35 years.

Liquid Applied Roofing Systems

Liquid applied roofing systems are specially designed coatings that are applied with either a roller or can be sprayed onto the roof. It is a layer thicker than paint that contains polymeric materials and white pigment to make the surface water proof, reflective, and opaque. This helps protect the underlying roofing material from degradation caused by harsh UV rays. Liquid applied systems can be the solution you need to extend your current roofs life span a few more years.
