How Can We Help You On Your Roofing Needs?

Thermal Shock to Your Commercial Roof

Thermal Shock to Your Commercial Roof

Recently Denver experienced huge temperature swings between highs in the 90s followed a couple days later by lows in the 20s and snow. From the perspective of your commercial roof, this is known as thermal shock and is common in Colorado. If you need a commercial roof repair, this type of weather only makes the damage worse.

Thermal shock can also occur from a roof getting really hot in the summer sun and then having cold rain fall on it. It’s hard on roofing and is made worse if there is existing damage from wind or hail or simple old age. Any break in the surface material of the roof will allow water to seep into the structure under the roof. This could cause wood rot and mold.

Signs of Thermal Shock

The obvious signs of thermal shock are buckling, cracking, and leaking of your commercial roof. Roofing materials expand and contract as temperature increases and decreases. The bigger the temperature swing, the more expansion and contraction takes place. If the roofing materials are old or are already damaged by wind or hail, this expansion and contraction will also cause buckling, cracking, and leaking.

If this damage isn’t repaired in a timely manner, it gets worse. Additional wind and hail can wreak havoc on a roof already damaged by thermal shock. And thermal shock can increase damage to a roof already affected by wind or hail.


We work directly with insurance companies. We know how frustrating dealing with insurance companies can be and we spare you this frustration. The process is smoother if you have been getting regular roof inspections. Having routine commercial roof inspections makes any claims process easier since it is evident the roof has been taken care of.  If you are having an adjuster look at the roof after making a claim, we can be there at the same time to help create accountability.  Without the roofing contractor present, some items may be missing from the Statement of Loss. Having the Statement of Loss corrected adds extra time to the claims process and prevents the roofer from getting started right away.

Gaco Roof Coating Systems for Commercial Roof Repair

Peak to Peak Roofing and Exteriors uses GacoFlex Solvent-Free Silicone Roof Coatings to repair damaged commercial roofs. GacoFlex is a flexible coating so it resists damage due to thermal shock. If the roof has existing damage and it is minor, these coatings can be applied right over the existing roof. The advantages here are obvious:

• Less labor costs to apply.

• Less landfill expenses since the existing roofing material does not have to be removed.

• No interruption to business in the building.

• The white color creates a cool roof which helps reduce the need for summer cooling by air conditioning.

• No permit is required, therefore, the Denver Green Roof Initiative requirements are not triggered.

Peak to Peak Roofing is a certified GacoFlex Silicone Roof Coating System installer and a commercial roofing contractor in Denver. If you own a commercial building and you need a new commercial roof, consider GacoFlex as an alternative to a full roof replacement. Because GacoFlex is a roof maintenance product and not a roof replacement product, you do not have to pull any permits to fix your commercial roof in Denver. GacoFlex Coatings have these added benefits:

• No degradation or cracking from ultraviolet rays.

• Permanent and does not stain.

• Prevents rainwater pooling.

• Resists mold and mildew.
