Blistering Shingles

Blistered shingles are a highly debated topic between manufacturers including CertainTeed and Tamko as well as home inspectors and roofing contractors. 

Blistered shingles can be caused by several reasons. Some manufacturers claim it is just cosmetic and will not affect a shingles performance and is part of the normal aging process. In some cases though, blistering shingles are due to an improperly ventilated roof causing the shingles to get too hot. 

If you notice a substantial amount of blistered shingles we recommend having a qualified roofing contractor like Drawdy Roofing & Vinyl Siding inspect your roof to determine the reason for the blistering.

 Buckling Roof Deck

The Asphalt Roofing Manufacturers Association lists several reasons for roof buckling, one being improper roof ventilation. (To learn more about how insulation and ventilation work together to keep your home comfortable as well as roofing ventilation recommendations click here).

Another reason a roof can buckle is due to improper installation of the underlayment, which can happen when an inexperienced roofing contractor installs a roof. Always work with an experienced roofing contractor that is licensed and insured and that can provide referrals.

Storm and Hail Damage

Damage caused by wind and hail cost State Farm and its policyholders more than $3.9 billion in 2012, according to an April 2013 analysis by the insurer. The property damage can be as minimal as a few broken shingles to total destruction of buildings. More on hail statistics here.

The Internet has a wealth of information on how to identify a hail-damaged roof, but little information is available on how hail actually damages an asphalt shingle and what can happen if the hail damaged roof is not replaced.

As explained by an Illinois roofing contractor Countryside Roofing and image provider: "Hail damage is a problem for roofs by breaking the fiberglass embedded in the asphalt mats of a shingle. This will eventually lead to cracks in shingles over time due to the fractured fiberglass being stressed from expansion and contraction caused by temperature changes resulting in water damage to the roof and interior of the home."
