What causes shingles to warp?
Both curling and buckling are most often caused by moisture of your roof decking or underlayment. Buckling shingles appear as if they are being pushed upward from beneath. It can be the result of a lack of insulation or poor attic ventilation, as well as improper installation.
Why are asphalt shingles rough?
There’s a reason for this: During the shingle manufacturing process, before the asphalt has fully set, granules are adhered to the surface of the shingle, giving it this motley, rough appearance. These granules are typically made from minerals or mineral fibers, but some are also made from metals like copper.
What causes shingle granule loss?
Granule loss which is uniform across the roof is usually a result of normal weathering. Over time, the bond between the granules and asphalt deteriorates, and granules will be loosened and carried away by runoff. Prolonged exposure to hail can also loosen granules.
What ruins asphalt shingles?
5 Causes of Granule Loss on Asphalt Shingle Roofs

- Schedule an Inspection with a Licensed & Insured Roofing Company in Jacksonville.
Why are my new shingles buckling?
Buckling is the result of asphalt shingles not laying flat due to the wrinkling of the roofing underlayment or the movement of the wood deck. During the summer months we normally experience high humidity, and as the old roof is torn off the wood deck is exposed and absorbs moisture.
Do roof shingles take time to settle?
The shingles need exposure to sunlight and warm temperatures so they can “relax” and lay flat. Depending on temperatures, this process can take from one week to several months. Do not lift the shingles and add roofing cement. The shingles will settle on their own.
What is the lifespan of an asphalt shingle roof?

How long does it take for new shingles to lay flat?

What can cause a gravel road to fail?
Standing water at any place within the cross section (including the ditch) is one of the major reasons for distress and failure of a gravel road. There is sometimes a need for special- ized equipment to do major reshaping of the cross section,especially in very wet conditions.

Asphalt: A bituminous waterproofing material applied to roofing materials during manufacture. Asphalt Primer: A thin liquid bitumen applied to a surface to improve the adhesion of self-adhering membranes and to absorb dust. Asphalt Roof Cement: An asphalt-based cement used to bond roofing materials.
What causes asphalt shingles to deteriorate over time?
Qualities. Thermal shock can damage shingles, when the ambient temperature changes dramatically within a very short period of time . “Experiments…have noted that the greatest cause of asphalt shingle aging is thermal loading.”. Over time the asphalt becomes oxidized and becomes brittle.
What can cause a roof shingle to fail prematurely?
Keep roofs clean and don’t allow tree branches or anything else to rub or scrape across the roof.
