What Really Happens During a Roof Evaluation?

It is important to schedule professional roof evaluations to keep your roof in perfect shape. Roof evaluations can be preventative maintenance by assessing the roof venting, flashing, and shingles. You learn about current hazards, potential problems with your roof, and how to mitigate them.

Here is the 4-step roof evaluation process.

1.Interior Inspection

A roof evaluator starts from the house interior. They will look out for any signs of roof damage not visible from the outside. The inspector checks the ceiling, attics, and walls throughout the house interior. Signs of water damage caused by a leaking roof include water stains, mold, wood rot, holes in walls or ceilings, and light coming from the ceiling into the attic.

2.Structural/Exterior Inspection

The evaluator checks the perimeter of the house and the roof overhangs for signs of water damage. They check the angled and level surfaces that could compromise your roof and how well the general roof system is holding up. Signs of a sagging roof include cracked or rotted rafters, sagging ceiling, damaged or missing collar, and rater ties. Tilting or leaning exterior walls also indicate a sagging roof. 

3.Material Inspection

Material inspection focuses on the roofing materials. The roof evaluator checks the shingles, flashing and venting. They will check them for any damage, rust stains, water, or moss blemishes. The evaluation also includes checking the flashing beneath the roofing materials for any cracks, leaks, or pests. 

Other things to look out for on the roof include clogged roof valleys, gutters, and debris. The inspector checks all roof penetrations like plumbing and attic vents, fans, pipes, and chimneys for failing or cracked seals. They can pinpoint raised roof planes and lifted overlaps at this stage. 

4.After the Evaluation

In some instances, it might not be possible for roof evaluator to get on the roof using a ladder. This is to prevent breaking delicate roofing material or a house with a risky pitch or height. However, there are different techniques to check the roof, such as using a drone or checking the perimeter shingles.

After the evaluation, they can provide an idea of the remaining life of your roof and a replacement estimate if necessary.
