There are a variety of factors that impact a roof’s performance. The life of a roofing system varies from its initial design and construction to the environment it faces and maintenance received.
Roofing Systems are comprised of many materials that when properly constructed add value and protection for your home. The common materials needed include: sheathing/decking, flashing, underlayment, ice and water protective barriers, ridge vents, ridge shingles, and other venting.
Inadequate roof slope, sagging, structures that excessively draw away under the load, inadequate draining and provision for expansion and contraction in decking material contribute to the roofing membrane weakening and splitting. Design deficiencies often can be corrected when identified with a roof replacement.
Lack of Maintenance
Often the greatest cause of premature roof problems is not finding and correcting minor roof issues in the early stages, especially for relatively low-sloped roofs.
The impact of hail can loosen, fracture or remove granules from your asphalt shingles. The granules protect the asphalt matting of your shingles from sunlight and ultra violet light (U.V.). The asphalt will deteriorate very quickly once exposed to the sun. This is the reason a hail-damaged roof will prematurely fail. Hail-damaged roofs may or may not be detected by the inexperienced observer. The results of a hailstorm will void the shingles manufacturer’s warranty, as they cannot warranty against “Acts of God” such as hailstorms.
Heat and ultraviolet rays cause roofing materials to deteriorate over time. Deterioration can occur faster on the sides facing west or south.
