Arrowline Do It Yourself Roof Inspection Guide

Why Inspect Your Roof?

1. Identify weaknesses and deteriorations in your current roofing system.

Roofing is the single biggest investment an owner makes in their home. If there are deficiencies in the current roofing system, they need to be identified and repaired prior to installation. There have been many cases of newly installed roofing having to be removed or repaired due to unidentified issues prior to installation. This is a costly and unnecessary incident that can be avoided through a thorough roof inspection.

2. Identify areas for possible improvement and strengthening the performance of your home.

A roofing project is the optimum time to identify areas where your homes performance can be improved. Never under estimate the value of items such as better attic insulation or tighter seals around doors and windows.

3. Rate the soundness of the current roofing system so that a decision can be made between removing or roofing over current materials.

If your current roofing system is in a good state of repair, a homeowner can often save the expense of removing and disposing of old roofing materials. In addition, two layers of roofing can increase to the insulating and protective factors of a roof.

How to Inspect Your Roof?

roof inspection form imageA roofing inspection involves examining both the interior and exterior of your home for signs of deterioration and then assessing those findings to identify both causes and solutions.

Construct a simple sheet or use our assessment sheet to record your findings. Our assessment sheet shows many of the most common areas to inspect and the types of damage you may find there. While each building is individual in nature, the information in the form will give you a good head start in identifying possible problems.

Begin by identifying the current roofing materials including type of roof covering, flashings, penetrations, drainage system and the age of the roof. Outlining your area's climatic conditions is also important as varying weather conditions affect roof's differently.

General Roof Appearance

The overall roof appearance will give you a general idea of the condition of the roof. Your assessment should include an overview of the structure (are the ridgelines straight and surfaces flat?) and identify areas that have been damaged or possibly weakened due to external factors (do you see debris buildup or algae growth?).

Detailed Roof Conditions

Examine your roof in greater detail paying great attention to areas identified from the general roof appearance. You'll be looking for both obvious damage such as missing roofing material or exposed fasteners and areas that could indicate deterioration such as staining.

Roof Features

Examine the features on your roof to ascertain possible damage or weakness. Penetrations should be firmly attached with flashing and sealants firmly in place. Drainage systems need to be directing waterflow away from your home.

Exterior Walls

The appearance of exterior walls can also give clues about a faulty roof structure. For example, stained or deformed siding could indicate drainage problems.

Interior Conditions

Damage to the interior of a home can be caused by a weak roofing system. The attic is one of the areas that show damage first. Is your attic full of moisture or is insulation sagging? If so, it could be a sign of roof leakage or indicate ventilations issues.

Walls and ceilings can also help identify roofing issues. Staining, moisture buildup around windows, non-aligned doors and cracks can indicate problems with an existing roof structure.


Assessing Roof Condition

Once you have inspected your roof, you will have a good indication of the overall soundness of the structure and have identified any areas that are in damaged or weakened conditions. The next step is to ascertain what caused any problems. Many times both the cause and the solution are obvious. For example, a strong wind storm loosened some shingles or time, itself has led to degradation of seals around roofing penetrations. Both of these problems would normally be solved during the installation of a new roof. However, it is very important to be sure of the full extent of damage. Seals or flashing can be repaired but if those faults caused leaking which in turn caused rot in the roofing structure itself, this problem won't be repaired by installing new roofing materials and needs to be dealt with either prior to or as part of your roofing project.
