Metal Roof Leaks

Metal roofing continues its climb in popularity as a preferred choice of roofing materials. Nonetheless, they are not immune to leaking and otherwise being damaged. Read on to learn more of some of the more causes of metal roof leaks.


 

Metal Roofing Screws

Most leaks on metal roofs are somewhat remarkably caused by roofing screws. Designed to seal out water by the means of compressing a washer made from rubber at the base of the screw head. When driven into the metal roof panel, the washer forms a gasket separating the screw head from the roofing panel. This should be simple but when screws are not driven in correctly or are over driven or when the screws are inserted at an incorrect angle, all of these scenarios can lead to metal roof leaks.

Over driven screws are usually the result of attempting to ensure a tight seal but in doing so causes the rubber washer to break. Conversely, with under driven screws, the washer never gets compressed properly. When a screw is driven in at the incorrect angle, only part of the washer is sealed and when screws miss the metal strut or the wood framing underneath, the result is nothing is sealed at all.

Stack Flashings

Stack flashings are a feature of metal roofs that can become very prone to leaking. Stack flashings are considered the boot or, if you prefer, the flashings around the pipes and tubes coming out of the metal roof, including air vents, plumping pipes and HVAC vents. Usually, stack flashings are constructed from a rubber-type material that is positioned flat on the metal roof to form a seal. it also squeeze fits around the pipe, forming an additional seal. Because the metal roof contracts and expands, it means these seals are under continuous degrees of pressure. In addition, the sun degrades the rubber material of the flashings that usually only lasts 50 percent of the life expectancy of the metal roof itself.

Missing Sealants

Metal roof sealants usually do not last anything like as long as metal roofing panels so they need to be replaced as part of a regular roof maintenance program. Sealants under trims such as Z flashing and metal ridge caps around roof transitions, pitch pans, counter flashings, and reglets will all need to be updated because of normal wear and tear. Therefore, it is vital to use a metal roof sealant specifically made for metal roofing.

Seams And Overlaps

Seams are located where 2 pieces of metal roofing overlap causing a condition known as a capillary draw. Capillary Draw is when water can actually travel uphill between two tightly joined pieces of metal. Butyl tape or sealant positioned between the two pieces of metal can break the capillary draw but when not installed and utilized correctly can be the cause of actually making the leaks worse than if none had been used at all.

Curb Flashings

HVAC units on Metal Roofs are normally positioned on curbs. Installing metal roof panels is a fairly simple process but the flashing that tests the ability of any metal roofer. HVAC offers little room for error when fabricating the flashing. The uphill side of curbs and the two upper corners of the curb flashing are difficult areas, especially when you are dealing with large HVAC units. Water often gets trapped behind the unit, standing behind the flashing which eventually erodes sealants and begins to leak. The more you caulk, seal, or tar the uphill side the more water it will hold. This Catch 22 is difficult to remedy without having to start again from scratch.

Pros and Cons of Metal RoofsMetal roofs are common all across Arizona and are popular around the Phoenix area for homes and businesses. It’s important you have professionals for metal roofing repairs and installation for your business or residential metal roof, as the roofs will also need regular maintenance over time. This post explains the advantages and disadvantages of metal roofs.


Whether you’re buying a home with one or thinking of installing, here’s what to know.

You may be putting a roof on a new home, or your existing roof needs a total makeover, there are many materials widely available. It doesn’t matter what roof style you have, metal roofs can be a great option because of their longevity, they are maintained easily, and energy-efficient. And you can choose from tin, zinc, aluminum, copper, or galvanized steel — just be sure your metal roofing material is tested and labeled by UL, FM Global, or similar, and that you get a hold of your local building department for any code requirements or permits you may need.

Advantages of Metal Roofs | Pros

Pro 1. Longevity

– Metal roofs usually last up to 40-70 years, depending on the material used. Traditional asphalt roofing material has an estimated life expectancy of about 12-20 years.

Pro 2. Durability

– Some metal roofs can endure wind gusts up to 140 miles per hour, will not crack or corrode, and can be impact-resistant (depending on which material you choose). Additionally, metal roofs don’t require the costly periodic maintenance that other roofing materials often need. However, they should be inspected regularly to make sure no repairs are needed.

Pro 3. Safety

– Metal roofs won’t spark and catch on fire during a wildfire or lightning strike.

Pro 4. Energy efficiency

– Metal roofs reflect radiant heat, which can reduce your cooling costs by 10%-25%.

Pro 5. Environmentally friendly

– Metal roofs are not only made up of 25%-95% recycled content, depending on the material used, but they are also 100% recyclable at the end of their lifespan as a roof. In comparison, most shingle tear-off waste ends up in landfills — up to 20 billion pounds a year.

Disadvantages of Metal Roofs | Cons

Despite their many advantages, metal roofs have some potential drawbacks.

Con 1. Affordability

– Metal roofs can cost as much as two to three times more expensive than other types of roofing materials. While the life expectancy of a metal roof is a lot longer, investing in a metal roof only makes sense if you plan to live in your home long enough to reap its cost benefits.

Con 2. Noisiness

– Metal roofs are known to be noisy, especially during a hailstorm or heavy rain. Adding additional insulation during its installation typically solves this problem, but usually increases the cost.

Con 3. Expansion and contraction

– Metal roofing materials that are attached as larger panels like to expand and contract. If they aren’t properly installed with fasteners that allow them to “breathe,” the panels can become loose and cause damage to them.

Con 4. Inconsistency of color match

– If a repair is needed or a room addition is added years later, it can be difficult to find an exact color match to the existing panels.

Con 5. Performance

– If water gathers anywhere on the roof because of insufficient installation or poor repairs, it can ultimately cause critical damage. Low-grade metals can also be less durable and thinner. Some metals rust in certain climates or dent a lot easier than others during hailstorms or even during installation.

Metal Roof Installation Labor Costs

Labor for an average roofing installation project costs $3,000, presuming the surface is a common shape without steep slopes or complicated characteristics. For high quality materials and complicated structures, labor will be closer to around $10,000.

However, it’s worth having it professionally done because proper installation ensures a long-life expectancy and greater efficiency – as well as a valid warranty. DIY installation can void warranty terms.
