We have years of experience serving the residents of this community. DeMarco is a preferred installer of the following products:

EPDM | (Ethylene-Propylene-Diene-Monomer)


This has been the #1 choice of architects, consultants and contractors for both new and replacement roofing projects for over 40 years. Available in both white and black for either absorbing or reflecting solar energy, EPDM is a proven technology with excellent value.

TPO / PVC | (Thermoplastic Polyolefin) / (Polyvinyl Chloride)

(Thermoplastic Polyolefin) / (Polyvinyl Chloride)

While offering the best solar radiant heat reflection properties, this roofing type was originally designed to combine the advantages of an EPDM roof with hot-air weldable seams for extra durability. TPO/PVC is also environmentally friendly and 100% recyclable material.

KEE | (Ketone Ethylene Ester)

(Ketone Ethylene Ester)

This is a tough, durable roofing material that has properties that make it highly resistant to grease and other chemical compounds. This material is very useful for Ohio restaurants and industrial roofing applications.

Metal | Standing Seam

Metal(Standing Seam)

Metal offers low maintenance paired with high durability and solar heating protection. Seams are raised above the roof and overlapped to protect your building from the elements. Repair work can generally be done by replacing damaged panels without disturbing the rest of the roof. This type of roofing tends to last much longer than standard roofing applications – up to 50 years.



Elastomeric coatings can be an effective and affordable solution to fix almost any kind of roofing leak. It provides seamless application over most roofing surfaces and its reflective properties help lower cooling costs.

Signs You Need Your Roof Replaced

Typically, a roof lasts for about 20-25 years. There are also a variety of telltale signs that will alert you that it’s time to call an Ohio roofing team. If you notice any of these signs, give our team a call or fill out a contact form and we can get started on your project! The sooner we can get things moving, the better. 

Signs You Need Your Roof Replaced | Interior Signs

Interior Signs

One step to identifying whether or not it’s time to fix or replace your roof is by looking for specific signs inside of the building.

Sunlight: Seeing sunlight coming in through the roof boards is a sign that there are cracks or holes present, which may also allow water to enter.

Water Damage: Visible water damage – often in the form of sagging spots, rotting boards, or dark stains and streaks underneath the roof or on the walls – is a sign that there is probably leaking, which can damage the building’s interior structure.

Signs You Need Your Roof Replaced | Exterior Signs

Exterior Signs

When it’s time to repair or replace your roof, there will likely be signs on your building’s exterior.

Curling Shingles: Shingles are meant to lie flat. If your roof has shingles that are curling or buckling, it may be time to have it replaced.

Damaged Chimney Flashing: Flashing made of cement or tar is more susceptible to water damage than metal flashing, and may need to be replaced.

Fallen Shingle Granules: Shingle granules in the gutters and dark patches on the roof are signs that the granules may have worn away and that your roof may be near the end of its life.

Damaged Valleys: Roof valleys help channel water and snow away from the roof and into the gutters. Damaged valleys could lead to leaks and water damage.
