Roofing Products

Shingles – Shingles are an affordable and effective option for steep slope roofs. Their affordability and visual appeal make them an especially good option for steep slope residential roofing. When installed properly, a good shingle roof can last up to 50 years. The most common problem with shingle roofs is poor installation. The national average lifespan of a shingle roof is only 8 years. Dave Loden Construction specializes in low-slope membrane roofing so we do not take on many shingle projects. However, when it comes to shingles there is only one product we recommend. Malarkey shingles stand above all others when it comes to value in the shingle market. They manufacture one of the top shingle products available. On top of offering a top of the line product they issue a fantastic warrantee and they are willing to stand behind it. Although a properly installed Malarkey roof should last decades without issue, they will honor their warrantees in the event of a failure. Along with a fantastically performing product and a superior warrantee, malarkey makes one of the best looking architectural shingles available. Dave Loden Construction sells, installs and recommends Malarkey shingles.

Pros

Cons

  • Affordability
  • Visual Appeal
  • Longevity (up to 50 yrs)
  • 120mph wind warrantee
  • Poor installation commonly causes premature failure (national average is 8 yrs)
  • Many companies/manufacturers do not stand behind their warrantees

 

Metal – Although there are many brands and companies manufacturing metal roofs, they all fall into two basic categories. Topically applied metal roofs and internally fastened roofs.


Topically Fastened Metal – Topically fastened Metal is often simply referred to as pro panel. This is much like tissues being called Kleenex. Pro panel is an extremely affordable option but it does have its down sides. Most people do not find this look to be visually appealing. As well, we at Dave Loden Construction do not recommend it to be used over an occupied space because it has a very short watertight life span. Metal expands and contracts a great deal as temperature changes. With this type of roof, the metal is screwed fast into place from the top with an exposed fastener. As the metal expands and contracts, it pushes and pulls against these fasteners. Eventually, the fasteners will tear larger holes in the metal and allow leaks. With an exposed fastener system, the fasteners are just that exposed. This presents a fault in that although the fasteners have a rubber grommet that serves to seal the hole they create in the metal, there are still holes through the metal roof. Every hole is a leak potential. Topically fastened metal roofs are at the bottom of the price range in all roofing. For this reason, the metal used is typically of lower grade and the color is painted on as opposed to a baked kylar finish. This means the metal and especially the color will deteriorate.  Dave Loden Construction does not recommend topically fastened metal roofs for occupied spaces.

Pros

Cons

  • Very Affordable
  • Poor visual appeal
  • Very short water tight life span
  • Painted metal scratches and fades
  • Low grade metal

 

Internally Fastened Metal –
Internally fastened standing seam metal roofs make a wonderful metal roof. When installed well, they can last upwards of 50 years and, on the right buildings, they look beautiful. The problem is they are also quite expensive. Internally fastened metal roofs stand out from other metal roofs because they are held in place with clips inside the seams of the metal panels. This solves two problems. One, there are no holes through the metal. Two, it allows the metal to expand and contract freely. Typically a internally fastened metal roof is going to be of a higher grade steel than topically fastened metal roofs. They also usually have a baked kylar color finish rather than paint. This means that the color will scratch less easily and last for decades. Dave Loden Construction installs and recommends PAC-CLAD standing seam metal roofing.

Pros

Cons

  • Kylar Finish
  • Extremely long life span
  • High Grade Metal
  • Beautiful Visual Appeal
  • Much higher cost

 

Membranes –
Membrane or single-ply roofs consist of a rubber or plastic sheet that is either fully adhered (glued down) or mechanically attached (screwed into place). They are commonly used on flat or low-slope roofs. This is our specialty at Dave Loden Construction. Membrane roofs are rolled out and secured. The rolls are then either heat-welded or glued together.

CSPE (Hypalon) – BEST
We at Dave Loden Construction view CSPE as the best single-ply product on the market. As mentioned above single ply roofing usually falls into one of two categories thermoset (rubber) or thermoplastic (plastic). CSPE breaks the rules, it fits into neither category. With CSPE you get the best of both worlds. Thermosets have an advantage in that they are very chemically stable. They remain pliable throughout their whole life. This gives them an advantage with impact resistance such as hail storms. Thermoplastics have an advantage in that the seams are heat-welded. This allows us to have a true weld, or a molecular bond at the seams of the sheets. Thermoplastics do not rely on glue. After they are welded the two sheets are homogeneously bonded, or monolithic. This means the two sheets become one. The sheet should fail before the seam comes apart. CSPE is technically a thermoset but CSPE can be chemically welded. Although it is a chemical weld as opposed to simply a heat-weld, CSPE still gets a homogenous monolithic bond. Because of its chemical stability, CSPE can be applied directly over almost any smooth surface. This is not true for thermoplastic materials. Its pliability and strength also mean it does not need to be used in conjunction with an expensive hard cover board like dens-deck to withstand hail. CSPE has an extremely long lifespan. Burke, our manufacturer of choice will issue warrantees up to 35 years. It would not be unfeasible for a CSPE roof to exceed 50 years.  Burke Hypalon is available in any color. Dave Loden Construction installs and highly recommends Burke Hypalon, our CSPE of choice. Dave Loden Construction has installed more warented Burke Hypalon in the state of Wyoming than any other contractor. 

Pros

Cons

  • Heat weldable
  • Chemical stability
  • Remains pliable
  • Approved for municipal water storage
  • Dimensionally stable
  • Extremely long lifespan
  • Sold in any color
  • cost

 

PVC – Better
PVC is the better membrane on the market. PVC is a thermoplastic membrane, the seams are heat welded.  This allows us to have a true weld, or a molecular bond at the seams of the sheets. Thermoplastics do not rely on glue. After they are welded the two sheets are homogeneously bonded, or monolithic. This means the two sheets become one. The sheet should fail before the seam comes apart. One issue with PVC is it chemical stability. This is where formulation and manufacture play a large role. PVC by itself is not very UV resistant; it also suffers from molecular migration. This means that the molecules in the PVC can separate. When this happens the material can become brittle and crack. Quality manufacturers have solved this problem through the formulation of their products. They also regulate the materials that PVC can be installed over the top of to limit molecular migration. Although this is a consideration, if a quality manufacturer is selected it will not be a problem. A properly formulated PVC should have a long life span. Sarnafil, our PCV manufacturer of choice issues warrantees up to 30 years. Sarnafil has PVC roofs currently in use that are more than 50 years old. Sarnafil PVC is available in any color. Dave Loden Construction installs and recommends Sarnafil PVC.

Pros

Cons

  • Heat weld able
  • Dimensionally stable
  • Long lifespan
  • Sold in Many Colors
  • Chemical instability

 

EPDM – Good
EPDM is a thermoset membrane. More specifically it is a rubber. EPDM is going to be the same material that an inner tube for a tire is made out of. Henry Ford once said, “You can have any color you want so long as it is black.” That is just how it is when it comes to EPDM. The advantages of EPDM are that it is very elastic and pliable. As with the CSPE, this makes it more resistant to impacts such as hail. It is also more affordable than PVC or CSPE.  The problems with EPDM are that it likes to expand and contract a lot and you cannot weld the seams. Most quality manufactures have taken steps to eliminate the expansion and contraction issues through stronger reinforcement and better installation methods.  The glued seams cannot be overcome so easily. The issue here is that the roof relies not only on the life of the membrane, but also the life of the glue holding it all together.  Dave Loden Construction installs Versico EPDM.

Pros

Cons

  • Elasticity
  • Affordability
  • Approved for municipal water storage
  • Glued Seams
  • Only available in Black
  • Dimensional Stability

 

TPO – Economical
When formulated properly, TPO can be a wonderful single ply roof. TPOs are used with great success and longevity all over Europe.  The product is extremely affordable and is a thermoplastic. Being a thermoplastic it has the large advantage of using heat-welded seams. The problem is, in the United States TPO is rarely formulated well. TPO hit the US market hard and fast. It was the new solution in affordable single-ply roofing and everyone started manufacturing a TPO immediately. This posed a big problem. Some manufacturers formulated it well, but many did not. The affordability of the TPO was being pushed hard and manufacturers were under pressure to get their prices down. To do this, many took out key ingredients in the formulation. TPO hit the market so fast there were tons of manufacturers on the market before ASTM was presented with the product. ASTM cannot write a specification that excludes any existing products. This means that the ASTM standard for TPO had to be very vague to accommodate all of the formulations already on the market. The TPO market was price driven rather than performance driven and the ASTM standard left room for some very low quality products. This made it very difficult for the manufacturers making a quality TPO to remain competitive. As a result TPOs in the US often have very poor formulation and suffer from a number of issues. TPO tends to have extreme reactions to temperature change and expands and contracts a great deal. This combined with poor UV resistance means that many TPO products will literally tear themselves apart by expanding and contracting as the material deteriorates. This can happen in the frame of a few short years.  Dave Loden Construction does not recommend using a TPO roof system.

Pros

Cons

  • Heat weldable
  • Low Cost
  • Dimensional Stability
  • Short Life Span

 

Coatings
Elastomeric coatings can be a great affordable and simple option to add life to existing metal, spray-in-place foam, or shingle roofs. If done in a proper and timely manner, a first coating can keep your old roof in the dry for up to 15 years. After that, it should be recoated about every 5 years.  At Dave Loden Construction we sell, install and recommend two roof coatings – Conklin’s Rapid Roof and Henry elastomeric roof coating. These are very similar to products you may see at any local hardware store. The main difference is the application rate. Most “do-it-yourself” coating products recommend a minimal coating rate. Commercially sold products have a much higher recommend rate. Coating an old roof can be a great option to add life to it. It is also a simple way someone can take care of their own roofing needs without hiring a contractor. Most roof coatings are sold only in white, but Conklin’s Rapid Roof can be mixed just like paint at your local hardware store to achieve any color you wish. The downfall of these coatings is if there is any “ponding” water present on the roof. These are areas that hold water for a length of time after precipitation has stopped. Standing water can rapidly deteriorate roof coatings. 

Pros

Cons

  • Do-It-Yourself simplicity
  • Affordability
  • Limited life span
  • Very susceptible to “ponding” water
