Your roof is the first line of defense for your home. It protects your property from damage such as high winds, rain, and even local wildlife like squirrels and birds. In addition to the usual weather factors, your roof also protects your home from the sun. Just like any other environmental damage, the sun also causes potential to damage your roof. In the greater Sacramento area, with its high temps and sunny days, chances are your roof may take on even more damage than usual.
Is Sun Damage Actually Harmful?
The sun is a powerful force of nature that offers a wide range of benefits but can also be harmful. Overexposure to the sun can cause the materials in your roof to break down and eventually fall apart, making it one of the top causes of roof damage in Sacramento! This will leave your roof and home open to the elements and can even allow wildlife to take up residence in parts of your home.
UV damage caused by the sun can change the chemical makeup of the materials used on your roof. As a result, the roof may start to deteriorate earlier than expected which can cause a loss in overall property value. Sun damage can also cause your roof to experience thermal shock which is when the material expands during high heat and quickly shrinks once cooled. This can shorten the lifespan and effectiveness of your roof. A poorly functioning roof will not only leave your home open to the elements but can also drive up the cost of heating and cooling your home.
The residential roofing experts at Harlan Quality Roofing have put together a list of common signs that indicate your roof is suffering from sun damage.
Signs Your Roof Has Sun Damage
- Ultraviolet Exposure Causing Color Change
One of the biggest signs that the sun has damaged your roof is when the color of the surface has changed to a lighter color. The UV light from the sun can effectively bleach the color of any surfaces overly exposed. If you noticed that your shingles have become much lighter than their initial color, sun damage is probably to blame.
- Peeling and Cracking on Roof Surface
If you notice peeling and cracking on your roof surface, it is most likely that the sun has caused coating damage to the top layer. This can lead to leaks in your roof that can have a negative effect on your insulation and even your foundation. If you notice leaks, strange mold, increased energy bills, or even a new vermin infestation, sun damage to your roof may be to blame.
- Curling Shingles
Like anything exposed to the elements, your roof will break down over time. If parts of your roof or even bits of shingles start crumbling, it’s a sign that sun damage has weakened the overall composition of your roof. Warped shingles are another sign of a damaged roof. This can be due to water damage, or sun damage. When shingles have curled edges, it is a sign that the damage has been caused by too much sun exposure.
Protecting Your Roof from the Sun
While there is no way to eliminate sun damage to your roof, there are some things you can do to reduce its effects. To start, it is a good idea to use high-quality roofing materials that have specialized UV protection. Lighter-colored roofing materials are better equipped to repel sun damage. Also, those that have reflective granules can also help deflect sun rays.

Why Roof Flashing is so Important!
Roof flashing is a vital component of your roofing system. It’s found and required in many locations to help shed or manage high water flow locations, prevent water intrusion, reduce or prevent the likelihood of dry-rot and to properly seal many different types of roof transitions including the perimeter below the shingles at eaves and rake or fascia locations, where a chimney, skylight, or many types of vents protrude from the roof surface as well as at valleys, step flashings at wall transitions, attic vents, etc. There’s a saying with flashing, “Think like a water drop”. As we all know, water flows down hill and if there’s a way in water will find a way. Often when a roof leaks old or damaged flashings are the most likely culprit.
Types of Flashing
Flashing is really a general term. Different names are given to flashing depending upon where it is used or even the shape of the flashing. Here are some common flashing types:
- Drip Edge or Nosing – installed around roof perimeters such as eaves, gutters or rakes.
- Plumbing or pipe flashing – installed at roof penetrations such as ABS, metal or gas pipes or code vents that extend vertically.
- Exhaust vent flashings – Used to manage attic heat, kitchen hoods, bathroom fans, dryer vents, etc.
- Step flashing – flashing used around a projection such as a chimney, skylight or sidewall transition on a pitched roof.
- Saddles or crickets – used where a chimney, skylight or other horizontal projection extends from the roof.
- Valley flashing – used where 2 roof planes intersect and form a valley
A Major Problem for Homeowners Repairing or Replacing Roofs
Unfortunately, in Northern California when replacing a roof the most commonly re-used components of a roof are the old flashings. We have often heard homeowners say they assumed the building department would “catch it” or “stop it”. However, the unfortunate reality is that while building inspectors check clearances around “hot pipes” on the roof and to make sure that nosing flashing is installed at the perimeter, they do not require the roofer to replace these other items if existing nor to replace items like plumbing flashings, vent flashings, skylight, chimney or saddle flashings. As a result, most roofers reuse these original flashing component. There are a number of reasons given for this such as: keeping their initial estimates down to capture more work, not wanting to increase installation time or pay for more costly fabrication on chimney and skylight flashings, and perhaps most sadly is the view that it helps reduce their liability as the excuse often used is, “Sorry, the leak is a flashing issue and we didn’t replace those flashings. But we could fix it for this much…”. Homeowners are often mislead to believe their flashings would be replaced because of estimates with minimal details or disclaimers such as “replace perimeter flashings”, “nosings” or “replace flashings as needed”.
A good and honest roofing contractor knows well the importance of replacing not just mandatory but all key roofing flashings such as plumbing, exhaust, chimney and skylight, nosings and valleys flashings. There are some flashings such as roof to wall flashings that installed behind siding which may maintain perfect condition when replacing a roof or stainless steel or copper flashings that will last many decades as well as other unique scenarios. However, most flashings eventually fail at the welded seams, high water flow contact points due to rust metal expansion and contraction or are crushed or damaged in roof removal, etc. Unless brand new these should be replaced.
In addition, when a new roof is installed with old flashings it substantially affects the overall appearance or aesthetics of the new roof. Paint does not adhere well to old or rusted flashings although some do attempt to paint them.
Thousands of roofs are replaced each year in Sacramento with new shingles and old re-used flashings. Many customers call us each year to help them deal with flashings issues which were reused by roofing companies who refused to honor a workmanship warranty due to “re-used flashings”. Sadly though most homeowners are not aware of this issue until after a leak happens sometimes well after the roof was installed and the company was out of business or used the excuses mentioned above.
Don’t fall victim to old, re-used flashing or cut corners. Quality flashing work is just as important as quality roofing shingles and roofing accessories. The job of flashing to shed water on your roof is critical and so is proper installation. Hire a quality roofing contractor who is willing to replace these important roof components and who communicates clearly that they will do so.
