Testing methods & process

How a roof survey works, start to finish.

Every engagement follows the same disciplined path — from scope to a documented, color-mapped report you can use for budgeting, repairs, warranty, or a claim.

STEP 01

Scope & access

We review the building, roof type, and history, then plan safe roof access and the survey grid.

STEP 02

Non-destructive survey

Instruments scan the assembly to locate trapped moisture and wet insulation without cutting the roof apart.

STEP 03

Verification cores

Where needed, selective core samples confirm readings and establish dry/wet baselines for accuracy.

STEP 04

Report & color map

You receive a written report of findings and recommendations, with a color graph marking any problem areas.

Wind uplift evaluation

5×5 Bell Chamber testing

For wind-uplift evaluation, we use 5×5 Bell Chamber testing under Testing Application Standard (TAS) 124-95, performed in conjunction with Irving Abcug, P.E., a Florida-registered and licensed engineer. The procedure determines the uplift resistance of an adhered or mechanically attached roof assembly to the deck.

The calculated pressure applies to the entire roof system. This procedure determines attachment rates for the field of the roof; the higher pressures required at corners and perimeters — where wind damage concentrates — are calculated separately.

Roof Moisture Surveys have proven to be a very effective method for improving the long-term performance and reducing the life-cycle cost of roofing systems. It is generally agreed that it is technically unwise and fiscally irresponsible to develop plans for the maintenance, repair, or replacement of a roof without first conducting a Roof Moisture Survey.
