Do I Need a New Roof? #7 – Masonry and Counterflashing

The breakdown of chimneys and other masonry walls are an indication of roof replacement. If water is coming in along the chimney wall or masonry wall it is either because the counterflashing is failing or the masonry itself is absorbing water.

This picture shows that the caulking has deteriorated to the point that it is actually missing and water can get behind the metal and enter your home. Deterioration can also occur on the concrete chimney cap which allows moisture to enter as well as weaken and destroy the entire masonry structure. By checking the caulking and maintaining the chimney with masonry sealant, the cost of repair or replacement are avoided.

Do I Need a New Roof? – #6 Storm and Animal Damage

Storms may cause the roof to be replaced before the normal life of the roof is reached. High winds can blow shingles completely off the roof or hail storms can damage the toughest of shingles.  Hail loosens the granules on the shingles creating dark spots on these shingles. The result is a shortened life span of the shingle. The loss of granules will allow the moisture to penetrate the core of the shingle accelerating the decomposition of the shingle.

 Animal damage, though limited to a specific area, is an indication that the roofing material or wood substructure has deteriorated to the point that animals can more easily remove the shingles, siding, or roof deck to get to the attic for shelter. This may require only a repair, but it is a good time to inspect the remainder of the roof to determine the overall condition of the roof.

Do I Need a New Roof? – #5 Exhaust Vents

Exhaust Vents

Most homes have at least one type of exhaust fan that exits into the attic. The most popular is the bathroom fan, but others include kitchen exhaust and dryer vents. If the fan exit through the attic it is important that it also is vented to the outside of the roof. If not this hot moist air will cause severe condensation in the attic and even mold growth. Here are some examples of what a fan looks like in the attic unvented and then vented to the outside:

There are vent kits that can be purchased at you local home improvement store to do this yourself. It includes the flexible pipe, attachments and the vent installed on the roof. We hope to have a video out soon that will give you the step by step process for correct installation.  If you would like to be notified, contact us.

Do I Need a New Roof? – #4 Ventilation

Poor Ventilation!

Damage due to poor ventilation

Another major factor that determines how long your roof will last is ventilation. If there is inadequate ventilation, problems like condensation in the winter and excessive heat inthe summer will shorten the life of the roof system and cause major damage to the wood deck. Attics need to ‘breathe’. This picture shows what happens to the plywood when condensation builds up due to heat loss and there is inadequate ventilation.

This adds to the expense of roof replacement. To solve the problem, make sure there is at least R-30 insulation in the attic, and soffit vents and attic vents in the upper part of the roof. Here are 3 different types of roof vents available:

Do I Need a New Roof? – #3 Granule Loss

Curling Shingles on a Roof

Granule Loss

When a roof reaches the end of its life the granules on the shingles come off more readily as the asphalt that holds them in place begins to deteriorate.  Watch for granules in your gutters washing out onto your lawn, or the roof turn dark as the asphalt is exposed. Shingles may begin to curl when asphalt breaks down allowing water to penetrate the core of the shingle.

Plumbing Stack

Plumbing Stacks.

Another problem that occurs with roofs put on in the last 10 years is the deterioration of a plumbing stack boot that is made of neoprene.  It has a tendency to dry out and crack allowing water to run down the pipe into your home through the walls. Sometime the ony evidence of a leak occurs in the basement or whereever the first bend in the pipe is located. Installing a new boot will last the remaining life of th eroof.  If you are in need of a new roof, I would recommend a lead plumbing stack cover which will outlast any roof system.
