TPO for Commercial Roofs

TPO, or Thermoplastic Polyolefin, is a synthetic rubber compound that is one of the most popular roofing solutions for commercial buildings today.

There are many notable advantages to installing a TPO system on a commercial building. For one, TPO can be fused to create a highly reliable, long-lasting seam. In addition to its strength, it is a heat-reflective, energy efficient material that was created to withstand the effects of ozone, chemical, and ultraviolet exposure. The materials’ ability to endure these types of effects is what makes it such a cost effective option.

TPO comes in several different thicknesses and can be mechanically fastened, fully-adhered, or ballasted, depending on the existing structure. It is most commonly applied in a white color to maximize its efficiency. By reflecting heat and light, TPO guards the roof from absorbing and transmitting outside temperatures to the interior of the building.

Having a qualified roofer is essential when installing TPO. The estimator must assess the current condition of the roof and recommend the best system to install. Even the preparation to the surface of the existing roof is essential for proper installation.

Andrews Roofing has highly qualified, knowledgeable estimators and installation crews with several years of experience with TPO systems. If you are interested in inquiring about a new TPO roof for your commercial building, feel free to contact our office.

Our People: Joe Wicker, “The Detail Man”

Joe Wicker is definitely a valuable asset to us at Andrews Roofing. I would say that he is “the engineer type.”

He was born in 1963 in Dover, Delaware, but because his dad was in the Air Force he was moved around a little and ended up in Virginia Beach at age 5. He graduated with honors from Kempsville HS and went to work at his grand father’s roofing company that had been started in 1913.

He is an expert in various types of roofing because he has been in the business since then at every level from laborer, to roofer, to supervisor, to estimator and project manager. He is very familiar with roof types including shingles, slate, tile, and commercial flat and low – slope systems like built – up TPO, modified bitumen, and E.P.D.M. White TPO membrane and E.P.D.M. are examples of single – ply roofing membrane systems.

Here at Andrews, he is an estimator and project manager and sometimes sees up to 5 roofs per day. He is definitely a real hustler for us and we are very happy to have him around.

Joe is married to Colletta and has 3 boys. In his spare time he officiates football games with the South Eastern Football Officials Association because of his love of sports. By the way, he can build an electric guitar and of course plays them. He works with wood at home, making types of art such as bowls and pitchers, and even makes ink pens from wood and gives them to our staff at the office.

All this stuff is great, of course, especially the fact that he is a good husband and father. His strongest point as a team member at Andrews Roofing is that he is precise, hard-working and extremely dependable. We can always count on him to do what is right. Joe has been with us since October 2011 and we plan to keep him around for the long haul.

If you have a roofing problem or you need an estimate for a new roof, you can request Joe or one of our other consulting estimators. Just give us a call.

Thanks for reading.

Your Home Is Not A Submarine

I have said it before; Your home is not a submarine…and even subs leak!

Fiberglass – asphalt and other types of roof shingles, such as tiles, shakes, slate, are not water proof. They are designed to shed water on a pitched or sloped surface. The steeper the better. Steeper surfaces shed water faster and dry faster.

You can’t put shingles on a pitch lower than 2 in 12″[roof rises 2″ in 12″] . We do not recommend it on slopes below a 4-12 pitch without special conditions. Roofs lower than a 2-12 need a roof system designed for “low slope roofs.” These are single – ply membrane roofs such as TPO , E.P.D.M. , P.V.C. , or modified bitumen . And just because shingles are on it now does not mean you should replace that roof area with the same thing. Even if it doesn’t leak now , it may in the future.

No responsible roofer would use the wrong type of material. A good roofer looks at every roof on a case by case basis. For example: A low pitch or low slope roof in a heavily populated suburban area not near large open spaces of land or water is not the same as one facing north on the river in Hampton Roads, Virginia cities such as Portsmouth, Norfolk, Virginia Beach, Chesapeake, Suffolk, Smithfield, York Town ,Hampton, or Newport News.

I might nail a shingle roof on a 3-12 pitch on the first roof described above, but not on the second. On the second I might recommend a low slope roof system or maybe install ice and water shield under the shingles in case wind driven rain forces itself in. And I might even use stainless steel roof nails so they won’t rust out by being wet too often for too long. #15 or #30 lb double layer asphalt saturated felt paper or “tar paper” roof underlayment might be an option as well.

Our roofers have been doing at this for a while so we have the ability to consult with you in these matters. We have seen all kinds of roof leaks and all kinds of roofs leak! We also listen to what the manufacturers say about how and where to install their roofing products . We are always sure to meet building codes.

We recommend the use of CertainTeed Landmark and other models of shingles made by CT because of their #1 rank on consumer reports and because of our experience over the years using all name brands. We took years to pick the horse we would race so you don’t have to worry about it!

So please remember: No matter how good the roofing material is, it must be installed in the right place and in the right manner to perform and do so for a long time. Ask the roofer and find out how much he knows before you hire him. The right decision in picking a roofing contractor or company is very important.

Thanks for reading!

The Best Warranty: Single-ply Membrane Roof Warranty

The best warranty in the construction industry is a single-ply membrane roof warranty (TPO or thermopolyolefin  , E.P.D.M., P.V.C., Modified Bitumen).

Firestone Building Products is leading in this area with their “edge to edge” roof warranty which covers all the roofing accessory products installed (membrane, roof insulation such as poly – iso board, fasteners, flashings, metal drip edge or coping or gravel stop, etc. These are on commercial flat or low slope roofs with positive drainage.

Of course one can get just a material or a membrane only warranty, ( residential or commercial) accompanied by the roofing contractor’s labor warranty, but I am speaking of a workmanship (labor) and material warranty by a multi-billion dollar company. Firestone even inspects the roof to be sure it is installed as per their specifications. A contractor must be certified by them to obtain one of these warranties which means you are sure you have picked a good roofer.  Any roofer can get a material warranty.  Only the best are Firestone certified.

These warranties are non pro-rated, have a no dollar limit, and are available in duration of 5, 10, 15. 20, 25 and 30 year increments. Yes, they can guaranty a roof against leaks and other defects for 30 years! They do this because they know their roof system will perform and last.

You know what non pro-rated means. No dollar limit means that 29 years from now, on a 30 year roof, inflation doesn’t matter. If a repair costs 20 times more than it does now, they still have to provide material and labor to do it. And most of the time these warranty repairs are made in just a few days because we make them for Firestone and Genflex Roofing Systems and they pay us to do so.

I would say that these roof system warranties may even be the best in any industry and not just in roofing or construction. Can you get one like it on a car or a microwave oven? Nope. I don’t think so.
