Owens Corning Deck Seal


Owens Corning® DeckSeal is designed to provide durable, dependable protection for challenging residential low-slope roofs, including additions, porches, and garages. Its multi-layer SBS-modified bitumen construction creates a strong barrier against water intrusion and changing weather conditions. Because the system is self-adhering, it can be installed without open flames, hot asphalt, or strong adhesive fumes. DeckSeal combines proven roofing technology with a clean, attractive finished appearance that complements the rest of your home.

APOC Roof Coating


APOC flat roof coatings create a durable, flexible barrier that helps protect an existing roof from UV exposure, moisture, cracking, and severe weather. When the underlying roofing system remains in serviceable condition, applying a coating can extend its useful life without the cost and disruption of a complete roof replacement. Reflective APOC coatings may also reduce roof temperatures and cooling costs, making them a practical, budget-friendly restoration option

The Questions Homeowners Ask Most

How long does a flat roof typically last?

A properly installed and maintained flat roof typically lasts between 12 to 20 years. Its actual lifespan depends on the roofing material, installation quality, drainage, weather exposure, and regular maintenance. Routine inspections and addressing small problems early can help maximize the life of your roof.

There is no single best material for every flat roof—the right system depends on the roof’s slope, drainage, structure, budget, and exposure to the elements. Modified bitumen is an excellent residential option because its durable, multi-layer construction provides strong waterproofing and puncture resistance. At Rise Exteriors, we evaluate your roof and recommend the system best suited to protect your home.

Flat roofs are built with a slight slope that directs water toward gutters, drains, or scuppers. Water that remains for more than approximately 48 hours may indicate clogged drainage, inadequate slope, or low areas in the roof. Persistent pooling should be inspected because it can accelerate deterioration and increase the risk of leaks.

Flat-roof replacement prices vary considerably, with national estimates commonly ranging from approximately $4 to $14 per square foot. Your final cost depends on the roof’s size, material selection, accessibility, existing layers, drainage requirements, and the condition of the underlying wood. An on-site inspection is the most reliable way to provide an accurate, transparent price.

A localized issue on a newer roof, such as a small puncture or isolated flashing failure, may only require a targeted repair. Replacement may be the better investment when the roof has recurring leaks, widespread cracking or blistering, saturated insulation, extensive pooling, or has reached the end of its expected lifespan. A professional inspection can determine whether the damage is isolated or affecting the entire roofing system.
