Design Your Standing Seam Metal Roof for Optimal Performance in Cold Weather Climates

If you’re planning on installing a new standing seam metal roof and you live in a cold weather climate with snow, keep in mind some design considerations that, in the long run, are sure to protect you against problems with snow and ice accumulation and removal during the winter months. Here are some tips:

  • Choose a design with a cold roof. Keep the entire roof as cold as the eaves. Ventilating the underside of the roof, insulating the attic floor, and plugging air leaks are usually the answer.
  • Consider a roof color with a high solar absorption value that will help thaw snow and ice.  Colors such as bronze, brown, or dark gray versus white or light earth tones will help do the trick. Continue reading

Drip Edge: Insurance Against Those Wet Roofing Woes

Your existing shingle roof has had it and you’ve decided to replace it with a standing seam metal roof that will last twice as long and add value to your home when it comes time to sell it.

Aluminum Drip Edge from Englert is available in 4" and 6" sizes.You’ve gotten bids from two or three roofing contractors and you’re almost ready to make your decision. Most homeowners will trust their roofing contractor to do what’s necessary to replace the old roof but it doesn’t hurt to ask if your roof bid includes drip edge. A drip edge is a metal (usually aluminum) strip which extends beyond other parts of a roof and directs rainwater off the roof away from the fascia and into the gutter. The edge is configured so it prevents water from blowing under your roofing. At the same time, a lip along the edge makes water drip down out and away from your house, instead of directly down the side of the wall or fascia. In effect, it is an effective way to prevent water damage all the way from the roof to the foundation.

A drip edge provides a neat, straight edge to the roof, and is positioned so that roof water drips in the middle of gutters, along their full length. This is important because a badly positioned drip edge—or no drip edge at all– can cause overflowing of gutters, over front or back.

Sometimes, a roofing contractor will charge extra drip edge, particularly if he is hand cutting and bending the material which does take a little more work, time and skill.

But drip edge is available from manufacturers like Englert already pre-manufactured in 6” and 4” wide, 10-foot strips for new construction and retrofit roofing projects respectively to save the contractor labor costs in cutting and bending metal. Nearly every roofing contractor will vouch that drip edge is giving your home extra protection. And even home exterior painting contractors who have painted miles of fascia board with and without drip edge will tell you the paint job and wood always fair better when there’s a drip edge to help protect them.

Accurate, Complete Shop Drawings a Plus on Metal Roof and Wall Panel Projects

A shop drawing is a drawing or set of drawings produced by the contractor, supplier, manufacturer, subcontractor, or fabricator on a metal roofing or wall panel project.

It is an essential part of any project and the quality of the drawings can influence whether a project will be done correctly to specification, whether there will be legal issues down the road about meeting spec and even whether the job will be completed on schedule.

Shop drawings are not produced by architects and engineers under their contract with the owner. The shop drawing is the manufacturer’s or the contractor’s drawn version of information shown in the general contractor’s construction documents. It is drawn to explain the fabrication and/or installation of the items, in this case, metal roofing or wall panels, to the contractor’s installation crews. Unlike an architect’s drawing, a shop drawing’s primary emphasis is exclusively on the particular product or installation, unless roofing and wall panel materials must be integrated with other materials.

The shop drawings should include information for the architect to compare to the architectural specifications and drawings. The shop drawing gives the architect the opportunity to review the fabricator’s and/or installer’s version of the product, prior to fabrication. Attachment of manufacturer’s material specifications, “catalog cut sheets,” and other manufacturer’s information like independent testing results and installation instructions should accompany these drawings. Manufacturers like Englert have all of this information readily available at their company websites so it can be downloaded onto a disk or easily printed out for attachment to the drawings. Some fabricators and manufacturers will provide symbols, data, or instructions concerning installation. This can include a list of other materials, such as fasteners or adhesives, appropriate but not included for the product. Continue reading

Is Your New Standing Seam Metal Roof Warranteed? Here’s One Way to Make Sure.

Your old roof has had it. There are leaks. You’ve got cracked, curled and missing shingles.  Asphalt granules are piling up in your gutter, indicating severe roof wear. And worn-out shingles are threatening to allow water or melting snow into your attic and even into your first and second floor living spaces.

To avoid these problems and get more life out of a new roof, you’ve decided to go with a standing seam metal roof. You’ve picked your roofer, signed a contract and even made sure the contractor is getting you a manufacturer’s paint finish warrantee on your new roof’s metal material.Image of Englert standing seam metal roofing on Florida home

You believe you’ve done everything you can to make sure your new roof will perform as advertised. But wait. Are you really sure you’re getting the manufacturer’s paint finish warrantee you’ve been promised?

There’s only one way to find out. Make sure the roofer who installs your new metal roof provides you with a copy of the paint finish warranty from the roofing material manufacturer. Nearly every manufacturer of metal roofing material will provide that warranty once the material has been paid for by the contractor and if the contractor has taken the time to fill out the warranty form provided by the material manufacturer. If the contractor hasn’t done both, you may be out of luck if something goes wrong with your new metal roof.

Most manufacturers make it convenient for roofers to go online and complete the warrantee form at the manufacturer’s a website. Piece of cake. If you want total assurance this has been done, ask that the warrantee be attached to your bill before you make payment.

That way if something does go wrong you’ll have both readily available to address any issue.

Problems with a Shingle Roof? Free Yourself Forever with a New Standing Seam Metal Roof

Thinking of replacing your old shingle roof with a new standing seam metal roof? Here are six telltale signs it’s time to get rid of shingle roof problems forever and replace them with a metal roof that won’t leak and will continue to look good for decades to come.

–Curling and buckling shingles are a sign that it’s time for a new roof. Shingles that are curling and losing granules means the roof is past its life expectancy or that the roofing material is defective.Worn out curling shingles on a house.

–Cracked or missing shingles is another sign that the roof is failing.

– Shingle granules in the gutters are also a sign of a failing roof.  Roofs tend to lose more granules toward the end of their life cycle. Also, a large pile of granules at the base of the gutter downspout is another sign of a worn shingled roof.

–Dark streaks on the roof caused by airborne algae that is sticking to the shingles. This may not necessarily harm the roof shingles, but it can make an otherwise beautiful home look tacky. Continue reading

Metal Roofing and Wall Panel – Helpful Tips for Assisting in the Specification Writing Process

An architectural firm is being asked to put together a competitive bid specification for a project that includes a standing seam metal roof or metal wall panels. The on-staff designers are not necessarily familiar with all the different metal roof and wall panel products available in the marketplace. But the owner has a tight deadline to produce drawings, written specifications and pricing and the architect has to get the work done quickly.

Architect reviewing project blueprint.Meanwhile, there are only days to complete the process if the architect is going to submit designs and specifications on time. Even under these circumstances, if a designer is going to go to the manufacturer for details and product usage information, there are a number of guidelines they can follow that will make the process easier and faster and make sure they get timely, useful information so the specifications are clear and easy to follow—the first time around.

Here are some tips to architects from our company’s product solutions staff which includes seasoned estimators, spec writers and architects.

Make the Construction Specification Institute’s Project Resource Manual required reading for specification writing.  This is the “spec writer’s  bible” by the only organization in the U.S. that has comprehensively considered the entire practice of specification writing for construction, including urging people to follow the four golden rules of specifying —be clear, concise, correct and complete.  This book contains CSI’s recommended practices for specification preparation, bidding and negotiating, and contract administration. There are definitions of terminology, descriptions of typical procedures, and examples of unusual situations. Continue reading

Complement Backyard Living Spaces with a Standing Seam Metal Roof

American homeowners increasingly are adding outdoor “rooms” for entertaining and recreation on their properties, according to a Residential Landscape Architecture Trends survey conducted by the American Society of Landscape Architects.

Garden shed with Englert metal roof.Nationwide, household participation in do-it-yourself lawn and garden activities showed an increase of three million households, translating into an extra $688 million in retail sales.  In total U.S. households spend about $29 billion each year on their lawns and gardens.

Results also show demand is growing for sustainability in these designs including recyclable materials, solar lighting and rainwater and gray water harvesting.

Decorative water elements such as ornamental pools, splash pools, waterfalls, grottos, and bubblers rated high along with spa features including hot tubs, Jacuzzis, whirlpools and indoor/outdoor saunas. Outdoor backyard structures also ranked well including pergolas, arbors, utility sheds and even tree houses.

And while they aren’t backyard recreation and leisure facilities, add to that canopies and carports which are also becoming targets for consumers concerned about sustainability, the use of solar power and water reclamation. Carports are used in a variety of ways and come in many shapes and sizes, but essentially they fulfill the same basic function. Carports, pergolas, gazebos, cabanas and large yard equipment sheds are ideally suited for PV deployment, providing sloped areas with direct sunlight. Continue reading

Choose the Right Underlayment Material for Your Metal Roofing Project

Underlayment products for use beneath standing seam metal roof systems should be carefully selected to provide a roof system that performs optimally throughout the life of the building. Several considerations must be addressed in the roofing system design, including ensuring that the four barriers needed in any building enclosure i.e., water barrier, thermal insulation barrier, vapor retarder, and air barrier are provided and are in the correct location for a given climate.

Long term, in-service roof performance can be affected by several important factors including: the metal roofing system and its expected service life, the climate at the building location, roof slope and geometry, and ambient conditions (temperature/relative humidity) within the building.  Improper selection of the roof underlayment may allow roof leakage or entrap moisture due to vapor diffusion or air exfiltration, which may accelerate deterioration of concealed components, shortening their service life and necessitating repairs.  Further, to provide longevity the underlayment should match the intended service life of the metal roofing system.

Metal roofing underlayment from Englert, Inc.Structural metal roof panel systems are designed to span structural supports without requiring a structural deck.  Hence, they do not typically include roof underlayment since the installation lacks a continuous substrate or deck to support the underlayment material.
For architectural metal roof panel systems, a roof underlayment is required to help control water leakage through the roofing system during heavy rain storms or under snow melting conditions. Upgraded roof underlayment is often specified in cold climates for additional protection against ice dam leakage, while high temperature underlayments are designed for use in high temperature environments where the in-service temperature can reach temperatures as high as 240ºF.

Meeting Standards for Metal Wall Panels: An Important Consideration in Building Design

There are thousands of building materials and products globally and virtually all of those used in a manufactured environment are subject to some form of testing and standards.

There are a host of international standards organizations that set standards for and test all kinds of products. There are de facto standards which means they are followed by informal convention or dominant usage, de jure standards which are part of legally binding contracts, laws or regulations and voluntary standards which are published and available for people to consider for use.

Picture of metal wall panels used in construction.The people who use an item (architects, engineers, contractors, etc.) or specify it (building codes, government, industry, etc.) have the responsibility to consider the available standards, specify the correct one, enforce compliance, and use the item correctly.

By the end of the 19th century, differences in standards between companies, was making trade increasingly difficult and strained. Hence the establishment of professionally supported standards organizations.  Progress was nevertheless slow. Suppliers in many industries including construction objected to standard material specifications and testing procedures because they feared that strict quality controls would make customers more inclined to reject items and default on contracts.

There was plenty of back and forth on the issue but the demand by material end users like the powerful railroad industry finally led to the formation of the American Society of Testing and Materials in 1898.

To this day, the ASTM remains one of the key standards organizations in the world. And in the area of wall panel, it provides some of the key standards for materials used in building design and construction. Continue reading

Tolling: When Coil Coating Experience Counts

Why do some highway signs look old and faded while others pop with color?  Why do the exteriors of some new trucks look great while others look like they’ve been traveling the highway for years? And how come your neighbor’s garage door to the left looks great but the one to the right built around the same time looks pasty and faded?

To get the answer, you may have to go back to that critical point in time when all of these metal products were large coils of aluminum or steel that had to be pre-coated or pre-painted to protect the metal and provide a base for decorations like decals, wraps, embossing and lettering. Coil-coated metal is indispensable in a variety of industries including the manufacture of household products such as lights and white lighting, residential and non- residential building products like garage and entry doors and window frames, sign stock, automation control panels, HVAC, industrial products and more.

Englert Production LineWe know as a company that pre-coats thousands of tons of metal material that there are different levels of quality for just about any pre-coated coil you can buy—whether it’s for a garage door, a tractor trailer body or a stop sign.  The metal gauge or thickness, the coatings chosen and even the paint line system used to apply the coating to the metal vary throughout the coil coating industry.

Demanding quality at this level can dictate how good a garage door looks when it comes time to sell the house , how long a tractor trailer will last after a few years on the road or how faded a highway directional sign will become when it exposed year after year to the elements.  If you’re a garage door manufacturer or you’re making sign materials positioned as premium products for their longevity and durability, be careful how you look for savings on production.

How good the product will look even over a short period of time is often directly related to how much the manufacturer is willing to spend to produce a quality product. If the industrial designer has been asked to create a premium-made garage door and the manufacturer’s purchasing agent knows the drill, the end product is pretty much guaranteed to look better and work better than a cheaper version. Colors will be more vivid, surfaces won’t appear faded or chalky and the aluminum or steel substrate will probably last much longer. Continue reading
