Most commercial buildings or custom-built structures are constructed with flat roofs. They’re durable and long-lasting, needing only routine maintenance for 20 years or more.
FACT: Flat roofs aren’t entirely flat, but rather usually have an inherent low slope. If the deck (wood, metal, or concrete) is not sloped, a slope can be installed with the addition of a taper system, allowing for the directional flow of water. Roofs are generally constructed in layers: typically a layer of polyiso, then covered by a layer of gypsum board material to add hail protection, and finally a waterproof layer (or membrane). This top membrane is generally "welded" together with a heat gun or robot, creating a waterproof surface. Different municipalities have different regulations regarding R-value, how many layers may be covered over versus tearing off and starting fresh, etc.
FACT: Flat roofs have many environmental advantages including the ability to be used as a roof garden. A waterproof, flat roofing system can be modified to support vegetation.
If your building has a flat roof, you need to know that it performs very differently than a pitched roof, especially in severe weather.
FACT: Hail and heavy rains can severely damage a flat roof. A weather event may just cause a "blister" or other disfigurements to the membrane, which may hold up for months without actually leaking. Presidential Roofing offers no-obligation, free roof inspections to assess the overall condition of your roof(s).
FACT: Sometimes the signs of damage on a flat roof are hard to spot. There are no shingles to notice out of place; so proper maintenance and inspections are key.
Do not ignore cracks of any size in your flat roof. Once moisture penetrates the roof and saturates the substrate or polyiso layer, you are in trouble and may be facing roof replacement, whereas preventive maintenance via patches can add years to your roof.
Enhance, maintain and repair your flat roof with the help of Presidential Roofing & Restoration.
Emergency service is available and annual inspections are encouraged by Presidential Roofing & Restoration…"The flat roof experts."
