Non-invasive infrared leak detectors can scan large areas quickly, detecting temperature differences that indicate hidden water intrusion before visible damage appears.
Flashlights and Extension Mirrors
High-powered LED flashlights with adjustable beams illuminate dark attic spaces and roof crevices where leaks often originate. Look for models with at least 1000 lumens and water resistance for all-weather inspections. Telescoping inspection mirrors extend your vision around chimneys, vents, and other hard-to-see areas without requiring dangerous positioning on your roof, revealing damaged flashing and broken seals that are otherwise invisible.
7. Roof Cleaning and Preparation Supplies
Brushes and Cleaning Solutions
Proper surface preparation is critical for any roof repair’s success. A stiff-bristled brush removes debris, mold, and loose materials from repair areas without damaging shingles. Pair this with a specialized roof cleaning solution that cuts through tar, oil, and biological growth. TSP (trisodium phosphate) mixed with water works exceptionally well for removing stubborn stains and ensuring sealants adhere properly to clean surfaces.
Debris Removal Tools
Effective roof repairs require complete removal of leaves, twigs, and granules from damaged areas. A compact rake with plastic teeth prevents further shingle damage while clearing larger debris. Include a powerful air blower to access tight spaces around flashing and valleys.
