Pictures of roof defects

 
 
 

  Damaged shingles were noted in the roof valley. This area will likely be prone to active leaks. Repairs will be recommended.

 
 
 
 
Picture of a drain vent pipe at the roof surface. The vent boot is loose and improperly installed.  The roofing shingles are covered with excessive debris which are aiding in the diminishing of the lifespan due to mechanical damage.  Repairs will be recommended
 
 
 
 
This damaged drain waste vent pipe boot has multiple pieces missing, some torn and/or incorrectly installed.  The roof covering is also damaged, below the boot.  Water intrusion is very likely happening here.  Repairs will be recommended.
 
 
 
 
 A torn drain vent boot on the roof.,  is a water intrusion point that will aid in the premature end of the roofing system.
 Repairs will be recommended.
 
 
 
Water pooling was observed on this flat roofing system.  Water pooling is an indication that a low spot is present in the roofing system where water can accumulate.  Proper drainage and pitch is necessary to ensure and maintain maximum roofing and structural lifespans.  Water pooling could lead to leaking,  structural damage and  a premature end to the roofing's lifespan. Repairs will be recommended.
 
 
Picture of a worn out drain vent boot on the roof.  The boot is improperly sealed and at  the end of  it's lifespan.  Water intrusion at this area is very likely.  Repairs will be recommended.
 
 
 
A picture of an improperly installed drain vent boot on the roof  which is nailed directly to the shingles, creating entry points for water and  also stressing the boot.  Repairs will be recommended.
 
 
 
A picture of a damaged lead drain waste vent flashing.  At the top of the pipe, the flashing is damaged with an open area that allows water to enter, between flashing and pipe, down into roofing members.  Water intrusion into roofing members, will aid in the premature end of the roof's lifespan. Repairs will be recommended.
 
 
 
 
In this picture major wear is observed on the roofing shingles.  Granular loss is very high and the roofing is near the end of it's lifespan. Repairs will be recommended.
 
 
 
 
The roofing system in the picture displays a non-standard method of application.  The roof covering appears to have been installed over existing covering and flashed improperly. Repairs will be recommended.
 
 
 
 
This picture depicts improperly installed flashing and roofing components, not a standard roofing method.  Water and snow intrusion points at numerous locations on the roof will lead to the premature end of the roofing system.  The chimney is also improperly flashed, with no cap, no cover, and no liner, which can all be observed from the ground with binoculars. Repairs will be recommended.
 
 
 
This is a picture of mechanical damage on the shingle roof. The shingle has abrasion damage with gouged and missing granules.  Mechanical damage leads to the premature end of the roofing shingles lifespan.  Repairs will be recommended.
 
 
 
 
This is a picture of shingles with severe wear, curling and degradation. The roofing material shown is at the end of  it's useful lifespan.  Repairs will be recommended.
 
 
 
 
The venting hood on the roof, in this picture, is improperly flashed and sealed to roof decking.  No determination can be made whether the venting hood is operable on observation because of the amounts of sealant and application method used are beyond normal methods. The venting hood is improperly installed. Repairs will be recommended.
 
 
 
The asphalt shingles, on this roof, are damaged.  The shingle tabs have chipped edges which are possibly from mechanical or weather damage.  Damage to shingles reduces the overall lifespan of the roof covering system. Repairs will be recommended.
 
 
 
 
This is a picture of a severely damaged shingle on a roof.  Water intrusion at this point is very likely and could also damage, the roof decking, below.  Repairs will be recommended.
 
 
 
In this picture the flashing at the chimney roof junction is damaged, missing in some areas and modified by a non-standard roof flashing method in others.  Water intrusion is very likely to occur at this point, leaking through to the roof decking, and could also lead to considerable costly damage to a home.  Repairs will be recommended
 
 
 
 
In this picture the roof shingle's improper installation on the roof at the rake edge, which is a non-standard method that creates a single continuous channel from the apex of the roof to the eaves, where possible water intrusion can occur, under the adjacent shingles and to the roof decking.  The water shedding design method is not present with this installation method. Repairs will be recommended.

 

 
 
 
This picture shows numerous trees and limbs coming in contact or in very close proximity to the roof.  Physical damage to the roof will occur when branch and limb movement make contact with the roofing system.  Debris from trees can also accumulate on the shingles and promote algae growth, fill the gutter system and reduce the lifespan of the roofing system. Repairs will be recommended.
 
 
 
In this picture, utility company cables are visibly in contact with the surface of the roof. Mechanical damage to roofing shingles takes place at the contact point when the cables move against the roof, reducing the roof's lifespan.  Repairs will be recommended.
 
 
 
A temporary tar patch over a severely damaged roofing shingle can be observed on a roof, in this picture. A tar patch is used as a temporary fix and is not considered a reliable, long term fix since tar will eventually crack over time, with exposure.  Repairs will be recommended.
 
 
 
 
This is a picture of an improperly flashed drainage waste vent on the roof.  The boot and vent has tar applied over the metal boot instead of a metal flashing system, also cracking is visible in the tar and at the pipe boot junction.  This should not be a permanent sealing method because it allows water intrusion in the gaps, between the boot and the pipe, to enter the roofing system.  Major water intrusion can lead to major damage and costly repairs to the interior and structure below the intrusion point.  Repairs will be recommended.
 
 
 
In this picture, the roof decking, or sheathing, at the junction point where drainage waste vent pipe exits through the roof  has  large, highly visible moisture damage.  Discoloration of the sheathing and evidence of water leakage is present, on the piping.  The boot and/or flashing is probably the cause of this condition.  Repairs will be recommended.
 
 
 
 
In this picture, missing and damaged shingle caps on the ridge of the roof and an open ridge along with exposed nails, are visible.  Water can easily enter this area and cause major roofing system damage.  Repairs will be recommended.
 
 
 
 
This is a picture of major shingle loss on a roof. Roof decking, or sheathing, is visible at the most exposed points of damage and the remaining asphalt shingles are damaged or near the end of it's useful lifespan. Repairs will be recommended.
 

 

 
 
In this picture, the chimney chase has a large gap in the siding at the roof chase junction towards the eaves. The siding on the chase is in contact with the roofing shingles and flashing is not visible at this junction.  Water intrusion will occur, at that point, leading to further damage below the chase and to the roof decking.  Repairs will be recommended.
