Shingle Overlays

We use proven methods in roofing your building. In years past composition shingles were manufactured using layers of tar paper, tar, and then ceramic granules to form a multi-layered water resistant roofing product. Nearly all modern shingle manufacturers are now using fiberglass as a stronger, more flexible, and more durable base for their shingles. If you have an old roof that has shingles with the old fashioned paper mat, the tell tale signs of wear are deformed shingles that curl and buckle and have an extremely rough surface. Modern fiberglass shingles do not curl or buckle, but as they age the granules wear off, the asphalt slowly evaporates, and the shingles become thinner and weaker. If the bottom halves of your shingles, or "tabs" as they are called, are breaking off in the wind, it means your roof is due for replacement. Re-roofing over rough shingles that have a paper mat is never advised as the uneven surface will be transferred to your new shingles and their normal lifespan may be reduced. If you have just one layer of fiberglass mat shingles and no damage to your roof sheathing, re-roofing over the existing roof will not cause harm to your new shingles and it will save you the cost of roof removal.

When re-roofing over existing shingles, we take extra care to ensure that your new roof will last for the life of the shingles. That means that unless you have a fairly steep pitch, we re-build the edges by sawing off the old edge metal and installing new metal.

We coat the bottom edge of the new roof with tar ensuring that the first shingle is fully adhered and there is no way for water, from heavy rains, ice, and snow, to wick up beneath the shingles.

Each new shingle is then aligned with the bottom edge of the existing shingles in order to get a smooth roof surface. Failure to use this placement method can result in "cupping" of the shingles that forms bowls on the roof that may hold water, and allow water to leach through your shingles which are water resistant, not waterproof. It takes a little more time and expense to install new edging on an existing roof, and to offset the shingles for a smooth surface, but the end result means that your new roof will be trouble free for the life of the shingle, and you don’t have to worry about damage to your soffits* from a rushed overlay job that does not seal the bottom edges of the new roof, or cupping of the new shingles that can allow leaks to occur.

The soffit is the wood or metal panels that are installed beneath the roof on the exterior or "overhang" areas of your roof.
