Truth be told, there's not much Denver CO homeowners can do when they find out their metal roof is corroding. Over time, even the best manufactured galvanized or galvalumed steel roofs will have its zinc or aluminum coating worn out allowing moisture and air to oxidize and accelerate its steel core's corrosion. While it's troublesome, make sure to do the following on a sunny day.
Often, steel, aluminum, and even copper roofs can still provide exceptional service if their structural integrity is still intact. Professional roofers in Denver CO can take a quick look and see whether or not it requires a full tear-off and if acrylic elastomeric coating can still improve its condition despite the situation.
If your roof is badly corroded, it's possible the metal seams have flaked and possibly tarnished parts of your roofing underlayment. Professionals can take apart your roofing seams carefully and replace your underlayment while they inspect your metal roofing's condition for a full and clear evaluation.
If it's clear that your metal roof is beyond saving due to excessive corrosion, it's best to do exactly as your roofer says and have it replaced as quick as possible. It's best to do this to prevent any possible water damage which can make your problems more expensive.
Champion Metal has a great guide on how to know whether or not it's time to have your roof replaced, read more about it below:
Your Roof is Turning 25
While residential metal roofing is credibly proven to last upwards of 30 years, other kinds of residential roofing materials may not hold up as well. If your roof is approaching 20 or 25 years protecting your house, then it may be a good precautionary measure to have a new one installed as soon as possible.
Shingles are Curling
Shingles can curl in two ways. There’s cupping, which happens when the edges of the shingles turn upward; and there’s clawing, which is when the edges stay flat and the middle starts to come up. Both are signs that leaking and other damage aren’t far away.
Whole Shingles are Missing
From a functional standpoint, there should be no problem with just replacing a few shingles here and there. However, any credible roof supply company won’t recommend repairing on a single-shingle basis. This could prevent more extensive internal damage from being discovered.
Granules are in the Gutters
If you just got a new asphalt shingle roof and you see granules in the gutters, there’s nothing to worry about. Those are just loose, extra ones. But if it’s been 10 or 15 years, that’s a sign of a larger issue. Not only can granules pollute the water supply, they can be a sign of rapid residential roofing deterioration. (Continued)
