Architectural Shingles

Architectural shingles are also known as laminated or dimensional shingles. They are among the highest quality roofing products because they are heavier, without requiring additional support under the roof. They are used by homeowners, usually of large houses, who like a distinctive look to their roofs. Their weight and design give a three-dimensional appearance. Some are nailed on in the usual way, while others in addition to nails, have interlocking tabs. They are also attractive to builders because of ease of installation.

Architectural shingles are made using a heavier mat base than a standard asphalt shingle. The mat base is made from fiberglass or organic materials, with some asphalt added. The back of the shingles are coated with a special material and granules are added to the top layer.

In most cases architectural shingles are designed to last for 30-50 years. They contain asphalt and minerals, are strong and flexible. They withstand extreme temperatures and other weather events. They are often available with a lifetime warranty.

Architectural shingles may be subject to algae and mildew damage if wet leaves and other materials build up. If you live in an area subject to these conditions consider this type of shingle with some copper included in the materials.

The heaviest are rated to withstand winds up to 120 mph, heavy hail and other impact. The interlocking models hold together extremely well. They are also highly fire resistant especially if they have a heavy granulated top coat. Those with fiberglass or rubberized asphalt are rated the highest for fire and weather.
