Common Roof Problems

February 15, 2017

Watching for common roof problems can save you significant money. Catching damage early and repairing it can save you the cost of a complete roof replacement.

Here are the most common problems to be on the lookout for...

Faulty Installation

Poor or Faulty Installation
A faulty installation of your roofing material can dramatically increase the likelihood of problems and reduces a roof system’s life expectancy. As shown here, sliding shingles is a significant sign of “high nail” shingles. There is a nail line on every shingle and when roofers are nailing very fast, it can be easy to accidently miss the thin nail line. You need to hire a professional to tell you if your roof has been installed correctly.

Leaks and Moisture
Wind, rain, hail, snow, ice, and debris can lead to moisture getting under the layers of roof and causing everything from leaks to mold and rot.Once you notice an issue on your roof, you should immediately have them repaired to prevent further damage from internal leaks.

Improperly Installed Flashing
Flashing is what seals the areas where your roof has been penetrated, such as vent pipes, sky lights, chimneys and heating and cooling systems. When flashing is poorly attached, it can cause open seams and laps and ultimately cause severe leaks around sensitive areas of your roof.

Critters
Small animals, birds and insects can cause a surprising amount of damage. It's best to evict them before they get a foothold.Having a regular inspection of your roof and siding is an inexpensive way to keep your home free from these unwanted guests.

Ponding Water
Water that is ponding or standing on your roof is a sure sign of a problem. Common causes range from debris buildup to improper drainage of gutters. The added gunk can weigh down your gutters and eventually tear them off your home. Also, will begin to rot out your eave exposures and eventually find a way into your home.

Damage
Wind and hail damage can cause punctures in roofing material. Wind will lift and break the seal causing full lift off or causing minimal lift keeping the shingles attached. Shingles that have minimal lift can be repaired, but if you wait too long, then they must be replaced. Hail damage will cause granules to be lost on the impact point. The granule loss will allow UV rays to degrade your roof, and eventually cause a leak point. Having your roof inspected immediately following a storm will be very beneficial, even if you don’t think damage was caused. Be cautious, though, that you have a reputable roofing professional inspect your roof; there are some that will talk you into a full replacement when it is not needed.

Trees
Overhanging tree limbs can rub on a roof, abrading the surface of the shingles and wearing away the protective top layer. Branches can also fall on the roof creating even more serious damage. Tree limbs should be trimmed back away from the roof as much as possible and if a tree is close enough to pose a threat to your home, it should be removed. This is a simple fix that every homeowner can do. If you don’t feel comfortable, then consult a professional.

Ventilation
Roof and attic ventilation is an integral part of making a roof last, and occurs naturally when vents are placed at the base of the roof (at the eaves or in the soffits) and near the top of the roof (the ridge) so that warm air can leave through the top, and cool air can be drawn through the bottom. Adequate ventilation regulates temperature and moisture levels in the attic. Left unchecked, heat and moisture can build up causing damage to rafters, sheathing, shingles, insulation, and raising energy costs, any may also lead to some ugly mold and mildew problems. When you have your roof replaced, make sure that the roofing professional certifies that the roof ventilation is adequate.

Thermal Splitting
"Thermal splitting," or "cracking" which in fact is in most cases actually a tearing of the shingles is considered by experts to be the principal current problem with fiberglass-based shingles. Originally observed on the lightest-weight (15-year life) shingles this problem has now been found across all shingle styles, weights (life ratings), and across most or all manufacturers of this type of product.

The thermal expansion of defective asphalt shingle product (common in the U.S. across many manufacturers in the early 1990's) followed by thermal contraction when cool weather approached, explained the tear shown in the shingle in our photograph just above. Finding this issue quickly can save you a lot of money as it can often be filed as a warranty claim. But waiting too long will cause very little payment or none at all.
