Asphalt Shingles

Asphalt shingles are the most commonly used roofing material in the US and consist of a base material called 'felt' that is made of rag fiber or fiberglass mat that is impregnated with asphalt for waterproofing. The asphalt is topped with mineral or ceramic granules that block ultra-violet light that causes the shingle to deteriorate. The granules also give the shingles their color and pattern. As shingles age, the granules fall off and the asphalt below dries up.

CD Kaller is certified by the leading manufactures of asphalt shingles and is able to offer the best - and longest - manufacturers' warranties

There are 2 main types of asphalt tiles: Architectural and 3-Tab (flat), some with special features such as solar reflectivity for a Cool Roof, and others with special treatments to prevent fading and discoloration for up to 50 years.

Slate is a traditional and all natural roofing material going back as far as the 1200s. Slate is mined in the Eastern United States, much of it in Pennsylvania, and is available in a range of sizes and colors: green, gray, gray black, purple, mottled green and purple, and red. Slate is beautiful, fireproof, and durable - installed and maintained correctly it can protect your home for 100+ years.

Inspection, Maintenance and Repair

Slate is very popular as a roofing material on homes, schools, churches, historic buildings and other structures in the Delaware Valley, especially on old Victorians. Many of these roofs are 100 or more years old and should be regularly inspected for damage both to the tiles and to the underlying roof. Any damage should be repaired immediately.

Slate can be difficult to work with. CD Kaller has 'slaters' trained and skilled in the installation and maintenance of slate roofing.
