Most Common Roof Problems

A roof will make or break your home, from future sales to durability. The roof is your home's first defense against damaging elements, and an important aesthetic feature. The failure curve of a roof indicates that it is the best it will ever be upon installation. That is why there is no better creed for roofing your home than getting it right the first time.

Problems with metal roofs

Metal roofing has become a strong component of construction, today and for the future. Metal roof systems today are by far superior to those in the past. Some may last for over 50 years.
Regrets don't appear in marketing brochures for metal roofs because there are few. Properly installed, a metal roof should need no repairs at all.
So why is it leaking?!

Leaks in metal roofs are likely the cause of improper installation. Roofs must be penetrated at certain intervals to attach the metal. Gaskets must be installed at these points to avoid water damage. If the gaskets are defective or ruined by over-tightening, the roof will leak around these penetrations.
All metal roofs have seams where pieces of metal fit together. Sealants are used to bond the pieces together. Older sealants will harden, shrink and come apart over even a short period of time, depending on stress components. The newer bonds are practically impervious to time, stress and weather. They are a very unique chemical formula that lasts indefinitely.

Problems with asphalt shingles

Asphalt shingles have had something of a green face-lift in recent years, with fiberglass reinforcing and organic cellulose components. Asphalt shingles are comparatively inexpensive, durable, recyclable and come in a wide variety of colors to match landscape and housing. Asphalt shingles last about 20-25 years.

Premature cracking can be a disappointing feature of some newer asphalt shingle formulations, as well as blistering. Blistering is bubbling observed beneath the surface of the colored granulation. Ultraviolet light can accelerate blister deterioration, sounding the final 'pop' and signaling loss of the protective granulation. If these damages occur rapidly, the shingles are defective and the manufacturer should be notified.

Problems with solar shingles

Solar shingles are fast coming on across North America as solar roof structures continue to increase in popularity. Solar shingles are actually photovoltaic cells that smoothly integrate into regular asphalt roofing. Each shingle produces about 13-63 watts of power, depending upon the shingle brand.
Solar shingles have a strong populist appeal and many are considering them; but, presently, there isn't much data indicating how long solar shingles may last.

Like other shingle designs, solar has its drawbacks, as well. Here are a couple.
Asphalt roofing is cheap, and lasts 25 years under ideal conditions. It is uncertain whether the asphalt material can be replaced without also replacing the solar-cell shingles. Installation of this roof makes the solar components and repairs virtually inaccessible, as well.
Solar shingles present the serious problem of an expensive product integrated into a less-costly roof that has a limited lifespan.

Common roof problems are exacerbated by the professionalism of the installer, the quality of the product and variable weather conditions.
