Steel roofing is much more durable than conventional types of roofing materials. While it cost more to install, it can last several years longer than regular asphalt shingles. This actually makes it more of an investment than an expense. It can also dramatically increase the overall value of your home.
Here are the two types of steel roofing:
Concealed Fastener Steel Roofing
Of the two main types of steel roofing, concealed fastener is the most expensive. The bolts and fasteners are neatly hidden within the folds of the panels that neatly interlock with one another. Nothing is visible from the ground except for the sheeting.
Because the bolts are hidden, there is less need for additional sealant to be applied as the roof ages. Less upkeep is required as well. Concealed fastener roofing is much more pleasing to the eye and will often lead to a higher resale price for your home.
Exposed Fastener Steel Roofing
Exposed fastener steel roofing is one of the most affordable roofing options. Steel roofing that leaves the fasteners and bolts exposed is less expensive, but requires more upkeep and general maintenance. Bolts and fasteners fill holes. This means that sealant must be applied regularly to prevent water from leaking into the home through the small openings.
Exposed fasteners are also at a much higher risk of damage from debris or limbs that may fall from trees. Over time, this can cause them to loosen or break off depending on how well the roof is cared for. Because the bolts and fasteners are in plain view, it will be somewhat easier to notice if they have been damaged. Prompt repairs are extremely important to maintain the integrity of the roof.
