dale-nelson By Dale Nelson, Roof Hugger LLC

Every year we provide framing systems that permit a new metal roof to be installed over an existing metallic roof. Sadly, in many cases the roof is being replaced not considering it had reached the cease of its useful life just rather because information technology had been improperly repaired. These repairs have many forms but almost are forth the order of tar, caulk, or other exotic conventional roof coating material that is rolled, sprayed or smeared on the metal panels with the hope of a long term "fix" to the leak trouble.

Metal roofs are the longest life, about maintenance costless roofs on the market, but any roof tin can and will eventually develop a leak. Metal roofs however are a specialty in and of themselves and contractors that exercise not specialize in metal roofing will oftentimes make wrong and/or seriously damaging repairs. Another of import attribute is that most newer metallic roofs have 20- to 40-yr finish warranties. Improper repairs can easily void these warranties!

Bold your metal roof has a leak where do you lot starting time?

1. Where is the roof leaking? What unit or point in the building has the leak appeared? Approximately how far from the eave going toward the ridge and from one building finish along the eave is the drip showing upward? Remember metallic roofs always take a pitch and h2o always runs downhill, so the leak is typically at that point or upslope from that point.

The almost common roofs are screw down and they will accept from 0.8 - i.1 fasteners per square pes of roof area. This means if you have a 10,000 sq. ft. roof there could exist equally many as 11,000 fastener penetrations through the roof. Older fasteners were often cadmium plated and notorious for breaking downwardly over time and creating a leak. Newer stainless steel and zinc cap fasteners take a significantly longer life span and should always be used. Standing seam roofs typically have very few exposed fasteners and those would typically be used at the eave or ridge of the roof. These roofs are very reliable and much less prone to leaking only on occasion, even they can accept a leak, console finish laps existence the virtually common problem.

Ok, I have the information I demand, at present who should I telephone call?

1. First and foremost, call someone who specializes in metal roofing. The typical "roofing contractor" may exist highly skilled with shingles, built-up or unmarried-ply systems but metal roofs are totally different. Metal buildings commonly have the manufacturer's logo and proper name on the peak or somewhere on the building. Call them for a recommendation; they will have a network of builders and installers they piece of work with. This will also protect any remaining warranty you may have. Don't inadvertently void your warranty.

2. If the building is too one-time or there are no markings remaining, I would suggest whatever local metal building contractor or metal building erector. Another great resource is the Metallic Building Contractors and Erectors Association (MBCEA). This is a group of qualified metallic building specialists that work continuously to maintain the highest quality of workmanship.

But my roofer friend says he can handle the chore. No problem, right?

1. Ok, possibly, merely inquire a lot of questions first. A roof repair does non mean you lot put caulk, silicone, tar or other strange material on the metal panels! If a fastener has failed, information technology should exist replaced with a new over-sized long-life fastener not covered with goop! Caulking or coating fasteners, panel side-laps or panel end-laps is not a fix - it is how you significantly shorten the remaining life of your roof!

two. Recall, metal roofs motility constantly. Information technology doesn't matter if they are screw-downward or continuing-seam, they motion. Considering of that, metal roofs also have their own specialized group of accessories for pipage penetrations, roof openings, snowfall retentiveness and other roof-mounted equipment. Never let another contractor - i.e.: plumbing, electrical, mechanical or other profession - to penetrate your metal roof. They don't understand them and they will non do information technology correctly. They too not properly trained on how to walk on a metal roof. Uncontrolled foot traffic tin practise serious damage to your roof.
