Article Library Metal Roof Repair And Maintenance-The Easy Way Back to articles In recent years metal roofs have become increasingly popular. They are beautiful, colorful, and add value to the building. One of the primary reasons that metal roofs add value is that they have a long expected lifespan. Additionally, if the roof is properly installed it should be capable of withstanding most climatic conditions, providing excellent protection from the elements. Nevertheless, as resistant as they may be, metal roof repair and maintenance is still essential to guarantee they will last as long as expected. The word metal is an extremely general one. When talking about metal roofs, there are a variety of options to choose from, such as steel, zinc alloys, aluminum and copper. There are coated metal roofs, which are the colored ones you see. Additionally, metal roofs are typically installed in one of two ways: as shingles or large individual sheets. All metal roofs have seams where the pieces of metal fit together. It is at these seams, and at penetrations through the metal for vents, skylights, etc, and where the roofs join a new plane like at the ridge, in the valleys, and along the fascias that metal roofs start running into problems. Furthermore metal roofs can rust through. In all cases, leaks are most prevalent in older metal roofs, and roofs that were installed incorrectly. Because leaks do occur, metal roofs require repair, restoration and maintenance. Metal roofs use sealants in the installation process. The sealants that have been available in the past do not last, getting hard, shrinking, loosing their elasticity and disbonding over time. Today, however, there is an alternative to the old butyls, ashphaultics and caulking sealants–it is a MicroSealant® called EternaBond®. A MicroSealant® is a very unique chemistry formulated to be virtually invisible to the ravages of nature. Eternabond® was designed as the ultimate metal roof sealing solution. Eternabond® is a MicroSealant® in an easy to use tape form, and it is used in similar fashion–but provides a permanent fix to any leak, regardless of the type of metal roof on which it is used. EternaBond® is quickly becoming the sealant of choice of professional roofing technicians, and because recreational vehicle roofs are so difficult to keep tight, EternaBond® is now being used by over 25 RV manufacturers in the manufacturing process. Constructed with the most advanced and aggressive MicroSealant® adhesive available on the market today, EternaBond®, which has a built-in primer, requires minimal preparation for it to be effectively used by even the most inexperienced novice. Easy and fast to use, it is designed to withstand extreme hot and cold temperatures and can expand upwards of 700 percent of its original size. Combined with its UV stable backing, an EternaBond® repair or restoration is a permanent repair. Available at many roofing distributors, RV distributors, and hardware stores, or, for added convenience it can be ordered directly via our website.

Metal Roof Leaks

Hello Bob, As far as I can tell, a standing seam metal roof may indeed be a better option for you, and here is why; you mentioned that the area you live in is subject to some serious winds and hail storms that can easily damage an asphalt shingle roof. If you go with asphalt, there is a significant risk of some serious roof damage from wind and hail down the road. You may save some money today, but you may well have to replace your roof again, just a few years from now, at which point I am pretty sure you will go with metal. Why not do it off the get go!? – You could get security and piece of mind by installing a metal roof, which would be a much better defense against strong winds and hail storms compared to a 30 year shingle roof. Also, as you have mentioned, there your homeowner’s insurance premiums would decrease if you choose to go with a metal roof. Furthermore, consider some significant energy savings if you opt for an energy star rated metal roof, which could help you save some 20% to 30% on your cooling costs. I dare say that in Central Arizona, it can add up to a good chunk of change!

I am currently looking to replace my damaged shingle roof w/ metal roofing of some kind and I am having trouble deciding which type of metal roof to go with. My home is a manufactured home (also known as a double-wide in some places) so I have a very simple roof w/ the exception of 1 dormer, 2 skylights, the furnace chimney, and several vents (I know that 3 of them are for bathroom/kitchen exhaust fans). The rest of the vents I assume are for roof ventilation (there are 6 all in a row along the ridge of the house). There is also venting in the soffits. I do not have an attic, I have vaulted ceilings. At this time, I have no tree cover in my yard & my home sits facing East/West so it is in the sun all day long & my home gets very hot as a result. I live in central WI. My questions: 1) My home is less valuable than a stick built home & metal roofing can be very expensive. Which type of metal roofing would you install? So that I wouldn’t “price myself out of the market” as realtors like to say 2) I have a question about ice/water shield. On one estimate, the contractor quoted for 3 ft of ice and water shield & another quoted for 6 ft. from my reading it sounds like 2 ft inside the wall space is to code. Which would you go with? Is more better in this case? Does it depend on the kind of metal roofing ? Please remember that my eaves are much smaller than a standard house. 3) Due to the sun/heat my roof will have to endure I am concerned with “oil canning” if I go with standing seam metal roofing. Is there something that can be done during the installation that can prevent it? 4) The last wind storm in my area had wind gusts of approx. 60 mph (which is how my roof became damaged in the first place). The prevailing winds usually come out of the West. Is there something that can be done on installation to help prevent wind damage in the future? 5) Can the venting be replaced with a ridge cap vent & still provide adequate ventilation? Sorry it’s so long but thank you in advance for any help

Metal Roof Leaks

“Re-coating systems help extend the life of a metal roof, and that’s money in the bank,” says Kate Baumann, director of marketing and procurement at Mule-Hide Products Co. Inc., Beloit, Wis. “Only positives come from restoring a coating on a metal roof and then maintaining that coating by re-coating the roof as necessary. An elastomeric acrylic coating acts like a shield, protecting the metal roofing system from the elements, including ultraviolet (UV) radiation, and ice and hail storms. It encapsulates existing rust, even if the roof is heavily rusted. It helps keep the roof weathertight by repairing leaks, cracks and seams. Re-coating also keeps the roof sound by moderating thermal shock that can elongate screw holes.”

Metal Roof Leaks

Aside from an improper/insufficient roof slope, there could be many other causes of a leaky metal roof; some may be quite obvious, such as a roof leaking due to metal shingles or standing seam panels being blown away by the wind during a storm. – This happens quite often actually, especially to the roofs that were not properly installed, nor properly secured to the deck with appropriate fasteners, in the first place. – If this is the case, you will need to assess the damage to see if the roof can be repaired by sourcing the same type of panels and replacing all the missing panels with new ones. You will also need to identify what caused the failure as most metal roofs are rated for wind uplift of 110 mph or greater. – For instance, you may find that the metal panels were blow away due to improperly interlocked metal panels, or due to the fact that panels were not properly secured to deck with appropriate fasteners. You may also find that there were one too many layers of shingles underneath a metal roof.
