Roofing Contractors - Asphalt Shingles & Flat Roofs

Asphalt Shingle Roofing Contractors

The most popular roofing material is waterproof asphalt shingles, which are light, relatively inexpensive and easy to install.  Costs can vary due to the color, quality and style of the shingles.  Improve Group Roofing is your reliable choice to help you choose the right shingles at the best price!  Asphalt shingles still dominate the US roofing industry, accounting for more than 70% of all residential, sloped roofs including new construction and replacements.  See some of the variations listed below. We install in Eldersburg, Westminster, Baltimore and all over central Maryland.

Strip Shingles

Also known as 3-tab shingles (due to the cut of the shingle) or simply strips, strip shingles are the original and most basic asphalt shingles. They are made from a single layer of asphalt and have a very flat appearance that typically offers a slate look. Since they are made from a single layer, they generally weigh and cost less than other asphalt shingles.

Dimensional Shingles

Also known as architectural or laminate shingles, dimensional shingles are the most prevalent asphalt shingles. These products are manufactured with two or more layers of asphalt that are fused together for a thicker and richer multi-dimensional appearance, and are engineered to mimic wood shake and natural slate roofing. Dimensional shingles are typically heavier than strip shingles, and have improved warranty protection.

Luxury Shingles

Luxury shingles are the highest-quality laminated shingles available, offering a differentiated appearance or functionality that outclasses that of dimensional shingles. Apart from being shingle ‘heavyweights’ that offer premium protection from weather, luxury shingles are stunning to look upon, presenting the highest quality, coloration, and dimensionality.

A flat roof looks and performs very differently compared to a traditional sloped roof such as shingles, tiles, or metal.  While a flat roof is not designed to be a water shedding system, because it has a low pitch, flat roofing can still protect your home or business from leaks and severe weather.

Today, there is a wide range of cutting edge flat roof systems that offer distinct pros and cons, longevity, and of course, price.

Flat roofs are a familiar sight throughout North America.  Any typical mall, warehouse, apartment building or school usually features a flat roof.  This roof type is easier to install over large surfaces and is the most common choice for  institutional buildings.

Thermoplastic Polyolefin (TPO)

When considering replacing your flat roof system, it is a good idea to give consideration to TPO roof membranes as a potential solution. TPO is in a broad family of rubber roofing materials and is a blend of polypropylene and ethylene-propylene rubber. This type of roofing often comes in gray or white on top, which can help to reflect the sun’s light and stop heat buildup within the building. This membrane resists corrosion, doesn’t promote mildew or algae growth and doesn’t require pressure washing.

Ethylene Propylene Diene Monomer (EPDM)

This durable rubber material resembles an inner tube, but it's engineered to resist damage from sunlight and it's highly resistant to scuffs and tears. EPDM is available in both black and white and it comes in a variety of widths and thicknesses. This type of membrane roofing keeps out the sun’s heat, reducing air conditioning costs, and also helping lower heating bills.

Torch Down

Torch down roofing uses a propane torch on sheets of modified bitumen to heat the material and adhere it to the roof’s surface. Once the layers reach the right temperature, the seams melt together to create a waterproof seal. There are many advantages to torch down roofing, including resistance to water, the ability to expand and contract without melting or cracking in hot or cold conditions, and a long lifespan.

Here are some signs that will tell you it might be time to replace your roof:

• Missing shingles
• Cracked shingles
• Granules in the gutters
• Moss and algae growing
• Water stains in the attic
• Sagging roof line

If you see any of these signs, contact us right away to schedule a roof inspection.

Many factors may influence the cost of a new roof—labor, materials, roof size, home location and more. Some of these costs are dictated by the size of your roof, local building code requirements and the extent of any existing damage.

Having a reputable, professional roofing contractor like Improve Group Roofing is your best guarantee of replacing your roof with quality materials and at a price within your budget.

A typical asphalt 3-tab shingled roof will last about 20 years, if it is properly cared for. A roof with asphalt architectural shingles will last from 30 to 50 years – again if it is properly cared for. Improve Group Roofing can help you decide which type of shingles are best for you and your home.

Having your roof inspected once a year is a good way to learn about current issues and potential problems so you can address both before any emergency situations. The two most obvious signs that your roof is damaged and should be looked at by a professional are leaks and blown off shingles. However, even if there are no signs that you need to have your roof repaired or replaced, a more thorough inspection may reveal damage that is not apparent to the untrained eye. So, scheduling an annual roof inspection is always a smart idea. Contact us to schedule a roof inspection.

Architectural shingles are high-quality dimensional or laminated shingles. They are made from a fiberglass mat base with ceramic coated minerals that are embedded in water-resistant asphalt. Several layers of material may be used to create the shingles. The shingles are thicker and offer different color variations to add three-dimensional light and shadows to the roof.

Architectural shingles cost about 20% more than flat three-tab shingles, but they last longer and add more value to your home. They were originally designed for larger, high-end homes, but they work on any building with a peaked or slanted roof. Architectural shingles have 25-50 year warranties.
