Roofing 101: Materials

Asphalt Shingles: With more than 75% of all homes being built with asphalt shingles, these shingles are the most commonly used material in the United States. And for good reason, considering they are the least expensive option, and provide for the easiest installation.  Although their lifespan isn’t the best, they should last 15 to 30 years. Asphalt shingles are available in two types: organic and fiberglass.

Tile Roofs: Concrete and clay tiles are manufactured in a vast variety of colors, to compliment most any Mediterranean, European, Mission, and contemporary or ranch-style home. Tile roofs have the longest life expectancy of any other roofing material. Centuries old tile roofs are still enduring today. Tile roofs are built to withstand most anything Mother Nature throws at them and are Class A fire resistant.

Metal Roofs: Metal roofs can be manufactured using a variety of materials, including copper, aluminum and stainless steel. They are commonly seen on bungalow, ranch, contemporary, and cottage style homes. Highly durable, and resistant to adverse weather, metal roofs are expected to last 50 years or more. Metal roofs are also endlessly recyclable; making them a viable choice for eco-friendly homeowners.

Roofing 101: Vocabulary

Coverage: The degree of weather protection offered by a roofing material: single, double or triple coverage.

Cricket: A built-up barrier to divert runoff around a chimney or at a transitional area.

Decking/Sheathing: The surface, usually plywood or oriented strand board (OSB), to which roofing materials are applied.

Is It Time For a New Roof?

Leaky Roof?

The roof is perhaps one of the most important parts of your home and knowing when to repair it is important. Roofing repair can be costly, so knowing when to repair or replace the roof can be a big decision for a family. A roof can last anywhere from 15 to 40 or more years.

The following are a few tips and guidelines to follow when making the decision about roof repairs:

  • 1. Missing or Cracked Shingles – If you notice this problem, it may be a sign that the tar holding shingles in place has worn out. At this stage, roofing repair instead of replacement might be a feasible option.
  • 2. Damp Spots in the Attic or Ceiling – If visible water spots are in the attic, it might be a sign that it is time for a new roof. Damp areas can also mean that the roof is nearing the end of its life.
  • 3. Buckling Shingles – Buckling can mean that new shingles might have been applied over old ones or that there is poor roof ventilation.
  • 4. Rotting Roof – Roof rotting happens when the roof mat absorbs the moisture from the air and the shingles disintegrate. This problem happens more in southern states.

Gutters, too, play a role in making a decision about your roofing needs. Paying attention to your gutters can prevent small problems from becoming bigger. Damaged or improperly installed gutters can allow water to get under the roof and lead to significant damage.

Winter Roof Repair, Gutters and Maintenance

Winter Roof Damage

Roofing provides a very important function by protecting buildings from increment weather such as rain or snow. This is especially apparent during winter months when snow and moisture sit on the roof creating a problematic environment where water can seep through the roofing. A house is one of the largest investments that a person makes in a lifetime and having proper roof maintenance and repair ensures a water free home. Jenesis Roofing specializes in roof repair, gutters, and shingles for homes and businesses. They recommend regular inspections of gutters and roofs to guarantee a stress free winter.

Rain gutters are on homes directing water around the roof and away from foundations. They are located on the edge of a roof where the water runs off a slant and into the gutters. It then runs into a downspout and away from the house. This system is designed to further protect the home from water damage that can occur around the roof and foundation. If water is not correctly directed away from a foundation, it can leak in through cracks and windows creating problems within the home. A gutter system should be inspected on a regular basis to keep them clean and prevent leaks. Proper working gutters are essential to the overall winter damage protection on any home. A large part of any roof maintenance project needs to include a close inspection of the shingles and a repair cost estimate.

Shingles can become damaged over time, and the problem is visually apparent when they are curling or missing. The professional staff at Jenesis Roofing is trained to look for damaged shingles that can create issues during the wet winter months. Proper roof maintenance and repair keeps homes safe from the water damage that can occur on unprotected homes. Jenesis Roofing is the place to call for any roof repair question because of their wide range of services. Having the proper roof repair is sure to protect the exterior and interior of a home. The time is now to call for an inspection before the snow starts to fall to make sure that the roof is ready for any type of weather.

New Roofs Are The Best Roofs

Are you thinking about having a new roof installed, but are not sure if it’s worth the time or money? Well, getting a new roof installed is definitely a smart idea. Your roof is one of the most important parts of your home because it helps protect the inside from dirt, snow, wind, rain and other environmental factors. It is also relatively inexpensive to install a new roof. Here are the benefits of getting a new roof:

It Raises the Value of Your Home

A new rooftop will certainly raise the value of your home. It is one of the first aspects of your home seen by potential buyers, so it is important for it to look good. Potential buyers will see your home as newer and nicer with new shingles and a new gutter system installed.

It Will Reduce Frequency of Repairs

With a new roof, you can avoid costly roof repairs for some time. In fact, you likely will not have the need for a single repair for at least several years. In the long run, a new roof can save over constant repairs.

It Will Lower Your Energy Bill

If your roof is old and deteriorating, air can escape your home, which will cause your air conditioning to work harder. A new roof can eliminate this creating a more energy efficient living environment.

It Will Be Safer for Your Family Members

Some older roofs can actually be health hazards. Worn roof in need of new shingles and/or gutters can endanger your family’s health. Bacteria and mold has been known to grown in these old roofs, leading to potential allergy and respiratory problems.

As you can see, getting a new roof is completely worth the money. When you have a new roof installed by Jenesis Roofing, you will have the peace of mind of safety, comfort, and efficiency.

Asphalt vs. Tile Roofing

Asphalt Shingles

Asphalt shingles have been around for a long time. They are one of the two preferred type of roofing material in use throughout the world. For most climatic conditions in the United States asphalt shingle material is the most preferred. Though a growing number of consumers are choosing a shingle that is tile, made of cement or clay. While other materials are available, at this time, asphalt and tile are the preferred material for quality roof construction.

One reason for the growth in popularity of tile is how the design fits for homes of southwestern design. For that reason, all across the sun belt from California to Florida, homes with stucco walls often use cement or clay tile. The tile type of shingle allows the attic of a home to remain cooler than possible with an asphalt shingle. In turn, a cooler attic helps keep the main part of the home at a more comfortable temperature. In addition to the cement or clay tiles naturally helping keep a home cooler, the colors used are lighter in color, helping to reflect the heat.

Tile roof-material is considered to increase the value of a home. This is due to the fact that tile generally lasts much longer than asphalt shingles. Also, many tile manufacturers have a warranty for their tile shingle products for as long as fifty years.

The initial cost of tile roofing is usually more than asphalt shingles. Comparison of the cost over the expected life time of each type of roofing, however, shows tile is more cost effective over the long run.

Some companies point to possible breakage, causing a need for repair, with a tile shingle but the same type of weather conditions that can damage tile can destroy a roof that uses asphalt material. Asphalt roofing, in many climates, can require cleaning to remove moss and plant growth, the same is true for tile roofing, but the repair process is easier, less time consuming, and therefore less costly.

Tile Roofing

As is the case with any product, the quality of the workers performing installation makes a big difference. With either product, a bad installation can result in significant expense in the future. Some asphalt shingles are now made in a laminated manner, bringing the cost of an asphalt shingle closer to that of cement or clay tile. Properly installed both types of shingles, asphalt or tile, can last up to a half century, which is a very long time.

There is a wider range of colors and textures available from asphalt roofing, which is one contributor to the current continued preference for asphalt by home owners. Both types of shingles can require repair with replacement of the damaged shingles, but asphalt shingles can sometimes avoid repair by using patches, instead of needing replacement.

In the end, it comes down to personal preference as to which type of material is selected. It appears, for the greater Denver metro area anyway, these two types of shingle material will remain the top choices of contractors and home buyers for some time to come.

Common Roofing Maintenance Issues

Roof-MaintenanceYour roof is an integral part of every house or building which protects us from the crazy weather that can happen above. Without the tops to our homes and businesses, we could have ruined interiors and possibly an unhappy, unhealthy place of residence/business. Read on to discover five common roofing maintenance issues and how they can affect repair and/or replacement costs.

Clogged or Damage Gutters

When a roof has been improperly cared for it can lead to clogged or otherwise damaged gutters. Since the gutters safely transfer the water from your roof to the grounds preventing water damage to the exterior siding and fascia boards, it is imperative they drain correctly. If the gutters do not drain properly, it can cause the water to backup underneath the shingles and seep into the walls causing expensive repairs and/or replacements.

Damaged or Missing Shingles

Shingles are the pieces of material that protect the top of your house or building from various weather conditions and other unforeseen incidents that may occur. If the shingles are damaged, missing, or balding, it can lead to water leakage…causing harm to your attic, walls, roof, as well as other possible structural damage.


Moisture can cause your insulation to become saturated and lose its initial r-value (how well the water heater’s insulation will help prevent heat loss through its tank). The added water and moisture can cause mold, rust, poor levels of indoor air quality, and extra weight on the roof itself…leading to even more costly repairs or replacements.


Unpredictable weather and poor roofing conditions can leave your home susceptible to cracks. These cracks can unknowingly leave easy access points for water and other unwanted pests like termites and other insects to enter. Cracks can also leave your home or building predisposed to our next issue…


Interior-Water-DamageAn older home or building may develop the aforementioned cracks that lead to unknown leaking. These leaks could go undetected for a long period of time as the water can travel through the housetop system before displaying any sort of visual evidence. Leaking can lead to ceiling damage, energy loss, mold, mildew, as well as other structural damage.

All of these problems are consequences which can arise from an improperly maintained roof. If your home or other structure is decades old or has noticeable damage to the gutters and shingles, or if there are more widespread problems due to cracks, leaks or moisture, repairing the problems may not be the answer. At this time it would be advisable to contact a professional roofing company like Jenesis Roofing who can expertly replace all the broken and/or otherwise damaged parts.

Gutters & Gutter Guards


Water is at once one of man’s greatest friends and also one of his greatest enemies. While it is necessary for life, water can also take life, destroy property, and remake landscapes. For homeowners in the Denver area, the fight to keep water contained is a constant struggle, one that has become easier with improved technology. One of the greatest innovations in home technology for containing water is the gutter system. When combined with a quality, well-maintained roof, properly installed gutter systems can improve the value of a house and keep water at bay for years to come.

Not only do gutters improve the look of a residence, but they also channel water off away from the home’s foundation where it could cause leaks or compromise the foundation. Furthermore, gutters are critical in preventing exterior water damage to a house. By preventing water from flowing down a home’s paint and siding, gutters prevent excess amounts of water from permeating the cracks and crevasses found in wood, vinyl siding, window seals, and door supports, water that eventually could make its way into the home.

However, gutter systems alone will not solve all water-related problems. To prevent gutters from becoming clogged with debris, gutter guards are made to block the entrance of leaves, pine cones, and seeds inside gutter compartments. With gutter guards installed over your gutters, water only will flow easily into the gutters to be carried away through the downspouts. Gutter guards will even prevent the wayward fly ball from finding a permanent home.

If you are in the market for a gutter system or gutter guards, Jenesis Roofing is your go-to roofing company. The professionals at Jenesis Roofing can install a new roof on your dwelling or business, fix your existing gutter system, or place top-quality gutter guards on your gutter network. Best of all, Jenesis Roofing provides a no-cost assessment to determine what gutter or other roofing products your home or business could use. Regardless of what roofing or gutter needs you have, Jenesis Roofing has the staff, equipment, and expertise to assist you.

Winter Roofing Installations – A Great Idea!

Just because the real heavy snows do not generally hit residential neighborhoods in the Denver area does not mean that your roof is safe from damage. While heavy snowfall is a leading cause for damage, it is the cold temperatures that will cause a serious amount of damage to any system that already needs to be replaced. With winter quickly approaching, you may be wondering if now is the time to repair or replace your shingles or roof all together. Read on and find out why scheduling your repairs with a trusted roofing contractor may be a great idea at the beginning of the winter season.

Cold Temperatures Can Cause Damage to Your Shingles and Gutters

While there are more than 300 days of sunshine in Denver, the temperatures can still get very cold in the winter. In the mild winters, the average temperatures in Denver are reported between 45 degrees and 60 degrees. These low temperatures are a drastic change from those in August and September. When the temperature drastically changes, it can cause damage to materials like the base of the roof system and shingles and gutters.

If you already need to replace the system, waiting for the winter to pass is not always a great idea. The winter conditions will only turn your bad system into a worse system. The shingles will continue to expand and contract as it the weather gets warmer and cooler. This can cause the materials to crack and warp and lead to a new roofing leak at the worst possible time of the year.

Make Sure Your Gutters Are In Working Order

Winter Roof InstallationsIf your gutters need replacing, this can cause even more damage. When you have damaged gutters during the winter they must be repaired immediately. These systems are designed to guide melting snow away from the home. And because the snow generally melts within a day or two of hitting the ground in Denver, these systems must be functioning properly. If the systems are damaged or need to be replaced, they can cause even more damage by leading to leaks.

Professionals Contractors Are Trained to Install in the Winter

You might think that choosing to do a replacement in the winter is not an option. This could not be further from the truth. The professional contractors at Jenesis Roofing are trained to complete installations in the winter and would be happy to do the work for you in any season. While it is cold, the cold temperatures are much more comfortable to deal with than the scorching heat on top of a roof in the summer. If you have been making excuses as to why you should not make the investment now, this is one you can cross off of the list today.

Jenesis Roofing is a top contractor in the Denver area offering repair and replacement services during winter. If you want to address problems with your system before water starts to freeze and temperatures start to fluctuate, schedule your appointment immediately and get the peace of mind you need to enjoy the cozy winter months.
