Common Metal Roof Problems And Repair Procedures

Metal has grown in popularity both for new roof installations and remedial applications, mainly because of its durability, low maintenance, and high heat reflectivity. The roofing material is also highly fire retardant, making it ideal for use in regions prone to forest fires. The visual appeal of a metal roof is also unique to any provided by traditional roofing materials, especially because it can be painted in different colors to brighten your home. 

However, metal roofing is vulnerable to the elements, and can thus develop several problems if not properly maintained. Here are common issues you should keep an eye on if you own this type of roofing.

Leaks and punctures

Metal shingles tend to easily tear under foot traffic, which can leave cracks that can let in water into the home. If minimal tearing occurs during installation, caulking can be used to seal any gaps or cracks. However, this often only serve as a temporary remedy, because temperature fluctuations will cause the metal to expand and contract, causing the caulking to eventually come loose.

The best way to avoid puncturing is to minimize foot traffic on your roof. If you need any repairs done, hire a professional roofer to handle the task. If you already have punctures or tears that are causing your roof to leak, have a professional replace badly damaged shingles, or apply metal sealant on small tears and cracks to ensure the roof remains waterproof.

Blow-offs and loose seams

Metal expands and contracts when exposed to temperature extremes, causing fasteners and screws to come off. If not repaired quickly, this can result in detached shingles, which would compromise your roof structure.

Blow-offs are a side effect of poor installation, where the flashing are not properly attached, causing some of the shingles to be blown off and leave gaping holes during extreme winds. Vigilance in roof maintenance is required to ensure the roof remains intact. Hire a professional roofer to regularly check your roof for missing and corroded fasteners and replace them with rust-resistant ones. caulk or trowel should also be applied on the heads of any exposed fasteners so as to protect them from the elements.    

Loose seams should then be located and fastened with screws and fasteners while missing shingles should be replaced as soon as possible (by professionals such as Dean Roofing Company). Any punctured or worn out washers should also be replaced with new butyl rubber washers to keep the roof seams watertight.
