Flat Roofs

Flat roofs are a great way to keep a building safe from water. Knowing exactly what to do with a flat roof will ensure you have a working roof system that will last a long time.

Though they may look good, and are very common, flat roofs do require routine maintenance and detailed repair in order to effectively prevent water infiltration. If this is done correctly, you’ll be happy with your flat roof for a very long time.

Flat roofs aren’t as glamorous and/or popular as its newer counterparts, such as slate, tile, or copper roofs.

However, they are just as important and require even more attention. In order to avoid throwing away money on short-term repairs, you should know exactly how flat roof systems are designed, the various types of flat roofs that are available, and the importance of routine inspection and maintenance.

A flat roof system works by providing a waterproof membrane over a building. It consists of one or more layers of hydrophobic materials that is placed over a structural deck with a vapor barrier that is typically placed between the deck and the roof membrane.

Flashing, or thin strips of material such as copper, intersect with the membrane and the other building components to prevent water infiltration. The water is then directed to drains, downspouts, and gutters by the roof’s slight pitch.

There are four most common types of flat roof systems.

Listed in order of increasing durability and cost, they are: roll asphalt, single-ply membrane, multiple-ply or built-up, and flat-seamed metal. They can range anywhere from as low as $2 per square foot for roll asphalt or single-ply roofing that is applied over and existing roof, to $20 per square foot or more for new metal roofs.

Used since the 1890s, asphalt roll roofing generally consists of one layer of asphalt-saturated organic or fiberglass base felts that are applied over roof felt with nails and cold asphalt cement and usually covered with a granular mineral surface. The seams are typically covered over with a roofing compound. It can last about 10 years.

Single-ply membrane roofing is the newest type of roofing material.

It is often used to replace multiple-ply roofs. 10 to 12 year warranties are typical, but proper installation is crucial and maintenance is still required.

Multiple-ply or built-up roofing, also known as BUR, is made of overlapping rolls of saturated or coated felts or mats that are interspersed with layers of bitumen and surfaced with a granular roofing sheet, ballast, or tile pavers that are used to protect the underlying materials from the weather. BURs are designed to last 10 to 30 years, which depends on the materials used.

Ballast, or aggregate, of crushed stone or water-worn gravel is embedded in a coating of asphalt or coal tar. Since the ballast or tile pavers cover the membrane, it makes inspecting and maintaining the seams of the roof difficult.

Lastly, flat-seamed roofs have been used since the 19 th century.

Made from small pieces of sheet metal soldered flush at the joints, it can last many decades depending on the quality of the material, maintenance, and exposure to the elements.

Galvanized metal does require regular painting in order to avoid corrosion and split seams need to be resoldered. Other metal surfaces, such as copper, can become pitted and pinholed from acid raid and usually requires replacing. Today copper, lead-coated copper, and terne-coated stainless steel are favored as long-lasting flat roofs, explains roofing Lexington KY

Quality Online Roofing Resources : this is a review of some quality online roofing resources namely, Garlandco.com, Roofing.com and Roofersreview.com which I find highly helpful to new roofers and non-roofers.

I recently had the need to come up with relatively useful definitions of some roofing terms and also some guides and opinions regarding roofing methods. I stumbled upon some useful online resources that provide the things that I need and also may also be helpful to other users out there.

Here is a list and some descriptions of some of the sites I have found:

1. Garlandco.com

It is a roofing company that has been in business since 1895. What generally caught my attention was their PowerPoint presentation that provides an overview of the most common types of roofing systems that are available in the commercial market place today. Other information include in the presentation are brief description, history and application of each system and lastly, the advantages and disadvantages of each roofing system.

2. Roofing.com

It is a forum all about roofing. Its main feature is a forum area where there are active members. All posts are related to roofing and most members are highly knowledgeable when it comes to roofing both in theory and in practice.

It also has a Knowledge base area wherein forum members can give inputs like answers to frequently asked questions and some roofing guides. Within this area, you can find the definitions to most roofing terms.

The site also has a section wherein you can view the number of roofing jobs available per state. It also has a directory of roofing companies categorized by state.

All in all, the site is quite user-friendly and highly informative. Most of my friends also think that it is one good online resource site if the subject is roofing.

3. Roofersreview.com

Is a highly informative site dedicated to roofing. Here you can find local roofers through browsing photos of their works. Also, this site has been suggested to me by members of Roofing.com. They say the pictures they upload to this site help them get quick answers from other users of the forum.

I would include the other sites that I find useful in another article which I may finish by next week. Until then, I hope you get the maximum benefit that you can from the following sites.
