Mod-Bit Roofing Professionals Long Island

Modified Bitumen Roofing

If your home or business has a flat or low-pitch roof, we highly recommend a modified bitumen roofing system. Mod-bit is a tough and durable roofing solution that’s been around for 50+ years.

Our Flat Roofing Services

We install single-ply flat roofing membranes for all low-pitched roofs. Asphalt shingles are meant for water run-off, and can’t support a flat roof. We offer flat roof replacements, installations, repairs, and coatings for Long Island homes and businesses. Call us today or contact us online for a free and instant roof quote.

What Is Modified Bitumen Roofing?

Modified bitumen roofing, also known as “mod-bit”, is a tough and durable flat roofing material. It’s composed of layered asphalt, rubber, and polyester. It’s the most cost-effective flat roofing solution, and extremely durable against the elements, chemicals and more. There are two available modifications to the bitumen. The first one is a plastic modifier called APP (Atactic Polypropylene). The other modifier is a rubber-based modifier, called SBS (Styrene-Butadiene-Styrene).

APP vs SPS

Atactic Polypropylene (APP)

APP is often referred to as a “plastic asphalt”. It uses a thermoplastic polymer, which increases the asphalt’s UV resistance and flexibility. This mod-bit roofing system works especially great in warmer climates.

Styrene Butadiene Styrene (SBS)

SBS mod-bit roofing is elastic and rubber-like. It’s extremely flexible, which yields a longer lifespan in areas where the temperature varies. The downside is that it has slightly less UV resistance, meaning that frequent coatings may be required. Since we receive all four seasons here on Long Island, we install SBS mod-bit roofing the most frequently.

Should I Install Modified Bitumen Roofing?

Modified bitumen roofing is still one of the greatest flat roofing options to install. It is one of three flat roofing materials we install here at Keenridge Construction. It’s been around for 50+ years now, and is still chosen to this day for being the durable and economical flat roofing choice. If you have a mod-bit roofing system, or any other flat roofing system, that has severe damage, give our flat roofing contractors a call. We’ll be there instantly to provide a free  roofing inspection and quote. From there, we’ll recommend the best options for you and your roof.

Benefits of Modified Bitumen Roofing

Mod-bit roofing has a number of benefits. Since there are two bitumen modifiers, we’re able to offer custom-made options that will uniquely benefit you and your property. Mod-bit roofing is durable, flexible, UV resistant, economical and water-proof. They are able to support foot traffic without a problem. If installed right, mod-bit roofs will never leak. Due to the asphalt and ruggedness of mod-bit roofing, they will stay leak-free for years.

Mod-Bit Roofing Installation

Here at Keenridge, we offer a few ways to install mod-bit roofing. Mod-bit roofing can be heat applied, cold applied, or mechanically fastened. For SBS roofing, especially on homes, we use a self-adhering method. We use Beacon’s Tri-Built SA SBS Cap Sheet product, which we believe is the best. However, this works best for small residential homes. To find out which method will best serve you and your roof, contact us online. We’ll get you a free and instant inspection and quote.

I'd like to thank Will and his team at Keenridge again for everything they did. My roof was leaking and Will was there the next day to discuss my options. We ended up needing a roof replacement, and he gave me a very affordable estimate to replace all of it. Him and his team ended up taking off all the old shingles and some old wood, and replaced it with new shingles in the same day! I'm very happy that I found a company like Keenridge for my roof replacement!

Everything was perfect, from the friendliness and professional introduction of Will and his company to the magnificent job on the roof. It looks beautiful. I especially liked the way they protected the rest of the house, the stoop, and walkways; and after the completion , checked the property for nails and debris. They truly respect their clients. Thank you.

I’m so thankful that I stumbled across this company. After getting quotes from a few different companies, what stood out to me is the customer service I received before I even signed the contract. They were fast , efficient and had great communication skills. I’m so pleased with my roof repair. In a few months I’ll be calling them again for my extension!

    Frequent Questions We’re Asked As A Professional Roofing Company

    Which Type Of Mod-Bit Roofing System Should I Install?

    It’s entirely dependent on where you live, what type of building it is, and so on. However, here on Long Island, we commonly install SBS modified bitumen. SBS mod-bit is better in areas where there are various climates. APP modified bitumen is better in areas where the sun will more often be radiating against the roof.

    How Long Does Mod-Bit Roofing Last?

    Mod-bit roofing will generally last 20 years without maintenance, and up to 30 years with general maintenance (inspections, roof coatings, etc.). Unfortunately, options like EPDM and TPO simply are more modern and last longer. The number one reason why mod-bit roofing fails after 20 years is improper installation. To get the most out of your mod-bit roofing system, work with flat roofing professionals! We’ve been installing single-ply flat roofing on Long Island for over 20+ years, and would love to help you!

    Can You Repair Modified Bitumen Roofing?

    It truly depends on the current condition of the entire roof and other factors, but yes, mod-bit roofing can be repaired and coated. However, with proper installation and maintenance, you won’t have to worry about stressful repairs. Work with flat roofing professionals today!
