Shingle Repair and Replacement

Asphalt shingles are a very popular roof system in Illinois. Our team has installed asphalt shingles from all the major manufacturers. GAF has a popular shingle (GAF HDZ) that comes with our bumper-to-bumper 25 year warranty and 50 year manufacturer warranty.  The shingles also come with an Unlimited Wind warranty which means you will never have to worry about blown off shingles again. 

The GAF HDZ shingles are more than just asphalt shingles. When installed by a KM Construction roofer they are part of a larger system that protects your entire home. The system includes specialty accessories and installation instructions to give you that full bumper-to-bumper 25 year warranty that only KM Construction can offer. 

The cost of an asphalt shingle roof system depends on material shortages but a typical roof with a GAF HDZ shingle will cost between $3.50-$5 per square foot.

Cedar Shake Roofing Installation and Repair

Cedar shake roofing involves a specific kind of wood shingle manufactured from western red cedar, cypress, pine, and redwood trees. There are many different types of grades of cedar shakes. KM Construction uses No. 1 premium grade which means they are 100% edge grain. These vertical grains ensure the highest shake performance. 

The shakes also come in varying degrees of thickness. The “medium” shakes are Premium Grade Western red cedar with a length of 18 inches and a thickness of ½ inch. The “heavy” shakes are a length of 24 inches and thickness of ¾ inches. 

KM Construction has a separate in-house crew that specializes in cedar shake replacements and repairs. We use special tools and equipment to ensure the highest quality installation. Our team uses stainless steel nails to prevent corrosion and have a copper sheet metal team to prefabricate flashings on all the cedar shake roof details.

Metal Roofing Installation and Repair

Metal roofs are gaining popularity and our expert team installs standing seam metal roof systems. The KM Construction team installs custom fabricated metal roof systems that are made specifically for your property and at a higher quality than systems advertised at big box stores. These metal roofs are typically used on commercial or high end residential properties. The metal roof system comes in a variety of  colors and includes accessories to create the look and feel our customers want. 

The cost of a standing seam metal roof system starts at $15 per square foot and could be as much as $25 per square foot depending on the pitch and design of the roof system. Metal roofs need to have special underlayment due to the heat they produce and a specialty crew to install the system. 


Frequently Asked Roofing Questions:

Q: Why should I get a roof inspection?

A: A roof inspection is important to help determine the health of a roof system and identify common problem areas. A trained roof inspector can notice small issues that indicate the roof is at the end of its useful life.  A roof inspection is critical when purchasing a new home because traditional home inspectors are often not roofing experts. The roof inspection should be done in good weather. 

Q: When should I replace my roof?

A: Some people wait until the last minute to replace a roof. However if the roof is leaking — especially in multiple areas — chances are the cost of replacement will be significantly higher than if it was replaced before those issues arose.

The most common indicators you need to replace the roof are its age, the condition of the shingles (curling or losing surface granules), the presence of daylight in the attic, and nail pops. 

If you find a lot of shingle granules at the end of your downspouts or in your gutters it might be time for a new roof. 

Q: What should I ask when getting roofing quotes?

A: The most important thing to ask about when looking for roofing quotes is the extent of the company’s experience. Many roofing companies stay in business less than 5 years and they are not there to help if any issues arise. The warranties they register may not have been done to specification and are voidable. 

That is why hiring a roofing company that has the HIGHEST level factory certification is important. KM Construction is a GAF Master Elite certified roofing contractor which means our crews are factory trained and are held to the highest installation standards. We have in-house crews to make sure that installation and safety training is completed every year. 

Q: How much does roofing cost?

A: Roofing costs are on the rise due to the increasing labor and material costs. The average asphalt shingle roof will cost $10,000 — or $132 per month if you choose to finance the project.
The cost of installing a good roof system using the proper materials and not cutting corners will be much cheaper than hiring a less experienced and lower price roofing company. 

Q: What is a “square” in roofing?

A: A square in roofing is a unit of measurement. In roofing the area is typically measured in squares not square feet. 100 square feet is equivalent to 1 square.

Q: What is composition roofing?

A: Composition roofing is the most popular type of roofing in the U.S.. This type of roofing is what is typically seen as asphalt shingles. The shingles themselves have a fiberglass core and multiple layers of asphalt and granules. These roofs typically last between 25 and 30 years when installed correctly and are an affordable option.  KM Construction installs hundreds of composition roofs per year and are factory certified with GAF to install them.
