10 Most Common Roof Problems

 

Watching for the 10 most common roof problems can save you significant money. Identifying damage early and repairing it can save you the cost of a complete roof replacement.

Here are the 10 most common problems to be on the lookout for…

 

Leaks and Moisture

Wind, rain, hail, snow, ice, and debris ... all of these and more can lead to moisture getting under the layers of roof and causing everything from leaks to mold and rot.

 

Poor or Faulty Installation

A faulty installation of your roofing material can dramatically increase the likelihood of problems and decrease a roof system’s life expectancy. An expert roofing professional can tell you if your roof has been installed properly.

 

Flashing Improperly Installed

Flashing is what seals the areas where your roof has been penetrated (like vent pipes, skylights, chimneys and HVAC systems). If flashing is improperly installed it can cause open seams and gaps and ultimately cause materials to blow-off. Improperly installed flashing can also reduce puncture resistance in your roof.

 

Ponding Water

Water that ponds or stands on your roof is a sure sign of a problem. Common cause range from debris buildup to improper drainage of HVAC units and gutters.

 

Critters

Small animals, birds, and insects can cause a surprising amount of damage. It is best to remediate them before they get a foothold.

 

Punctures and Penetrations

Wind and hail damage can cause punctures in roofing material. The sealant and flashing around penetrations (such as vents for household appliances and HVAC) added after the roofing was completed need to be looked at regularly.

 

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 damage that is serious. 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.

 

Something as simple as walking on your roof can cause damage. Many roofers install walkways with a double layer of roofing materials to allow access to HVAC or other areas in order to prevent damage.

 

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. Since warm air naturally rises, no mechanical process is necessary to create this air movement. 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 rising energy costs, and may also lead to some ugly mold and mildew problems.

 

Shrinkage and Blistering

Shrinkage is caused when the roof membrane (the layer under the tiles or shingles) shrinks, most often causing cracks or crazing in the upper layer. Blistering, ridging, splitting, and surface erosion of shingles can eventually lead to bigger problems.

 

Improper or Lack of Maintenance

Lack of roof maintenance is probably a roof’s worst enemy. Many problems start out as minor, such as the need to remove overhanging tree limbs or cleaning backed up gutters. However, when not corrected these problems can create serious damage. Routine inspection and maintenance can extend the life of your roof and that can save you a lot of money.
