For a very long time, asphalt shingles are popularly used for roofing solutions. Steel shingles have nevertheless gained immense popularity due to the several advantages they carry. Here are the six problem areas with regard to asphalt shingles that make steel shingles a better option.

Asphalt shingles are prone to blistering

Asphalt shingles invite blistering and contractors are often called to fix this issue. Some factors that cause blistering are accumulation of moisture in between the layers of asphalt shingles and poor ventilation of the roof that leads to trapping of moisture. Blistering leads to exposure of the roof, decking and the building to the nature’s elements. This can lead to the premature failing of the roofing system.

Curling is a prevalent problem in asphalt shingles

If this happens, the roof’s surface or corners might be seen turning upward. This happens at the end of the useful lifecycle of the asphalt shingles. After this stage, the shingles will shrink and demand a new roof. Thermal shock is the most common cause for asphalt shingles to curl. This happens when there are alternating highs in extreme temperatures one after the other. Similar to blistering, curling can also lead to leaks and the failure of roof following that. This does not happen with metal shingles.

Cracking is very common in case of asphalt shingles

Asphalt shingles invite cracking on their surface. This happens naturally when the shingles age. Deck movement can also accelerate shingle cracking. If the roof is older this is a highly prevalent issue. Improper installation of asphalt shingles is one of the common reasons for cracking of asphalt shingles. If this is left unattended, it can lead to compromising of the water-tightness.

Asphalt roof can loose granules

Though this is a lesser noticed issue in asphalt shingles, granule loss refers to the detaching of the top layer of the shingle. Eventually this can lead to the top layer falling off the asphalt shingle. Granules are the finely crushed stones that you see applied on top of the asphalt shingle sheets. Weathering and exposure can lead to the granule loss over time. However, this is not the case with metal shingles.

Asphalt shingles invite mold, algae and mildew

Asphalt shingles accommodate mold, mildew and algae growth over years. This is a highly prevalent condition where there is high levels of humidity. This looks like black streaks down a roof. This happens because of the organic substances in the asphalt roofs trapping moisture. One advantage of metal shingles is they do not invite mold, mildew and algae.

Missing shingles is a common issue with asphalt shingles

Asphalt shingles are installed piece by piece and it is highly possible for individual shingles to get detached and come off the roof structure. When a shingle happens to come off the roof, it is necessary to repair and replace the same without wasting any time. Not fixing this can lead to the home getting exposed to weather elements.
