NEW DECK & PORCH INSTALLATION, REPLACEMENT & REPAIR
Day after day, season after season, southern New England roof shingles are subjected to the ever changing elements of sun, heat, rain, cold, and snow. MA residential roofs are dynamic structures and actually move as the many forces of nature act upon it.
On any given day, your roof may be pounded by the sun’s destructive ultraviolet rays, stretched by the expansion of intense summer heat, or forced to contract from a sudden cold rain. Your roof never gets a day off! Over time these relentless natural forces will cause minor shingle defects, which if ignored, can cause major roofing problems.
Over Three Decades Of Roofing Experience
Though the signs of normal shingle aging vary, it may be time for a new roof if you notice:
- CURLING: Over time the asphalt in a shingle will harden, causing embedded granules to loosen and wash away. Initially you may notice the colored granules in your gutters. As hardening advances, the layers in the asphalt layers begin to shrink causing the edges of the shingles to curl.
- SURFACE CRACKING: Asphalt contains oils for flexibility. As they age, the oils are depleted due to heat. The shingles become more brittle and develop surface cracking. Stresses created by thermal shock and the flexing movement of the roof deck also increase the likelihood of surface cracking.
- BLISTERS: As a process of natural weathering, small open or closed bubble-like blisters may appear on the surface of the shingles. Blisters frequently result when adequate attic ventilation requirements are not met.
- STAINING: Shingles may develop dark streaks that are often thought to be soot, dirt, moss, or tree droppings. In reality, this streaking may be caused by algae growth. Most roofing systems are subject to algae discoloration, though it is most often visible on light-colored shingles.
