Small Polycarbonate Roof Fixes That Can Do Wonders

Not all polycarbonate roof issues require immediate replacement. Some only need a few tweaks and fixes to make it perform like it used to, or to make it look as good as new. These issues may be a small problem now, but can turn into bigger problems with higher bills and costs eventually. But how can you know if the problem can be done with a few fixes? Before you attempt to do it, try to answer these questions with a yes or no.

Do I need to get on the roof to do it?
Will it take days to repair the “small” problem?
Are the materials to fix it only found in bigger hardware stores?
Does it affect the functionality of my roof greatly?
Is the problem easily noticeable at first glance?
Can the damage be found in more than one specific area?

If your answer to most of these questions is a resounding Yes, skip this article because you might not be able to fix it yourself. The issues may need major repairs or even replacement, which only a professional could do. But if you want helpful tips to avoid a costly repair, then read ahead. For your safety and security, ensure that you have a stable footing and are wearing proper safety gears before climbing on the roof. Do not step directly on the roof, as it may be slippery and cause you to fall. If need be, stand atop the framing system.

Problem: Scratches on the Roof Surface

Quick Solution: Cleaning the Gutters

Minor scratches on a skylight roofing rarely compromise the functionality of the roof but it is easily seen and ruins the visual aesthetic of the roof. Although strong and durable, polycarbonate sheets can be easily scratched by leaves, rocks, and other dust particles brought by the wind. The quickest solution is to clean out the surface frequently, keep nearby trees and plants trimmed down, and to avoid using hard cleaning materials like tough brushes in cleaning the roof. Slightly sand the scratch using a fine-grit sandpaper, until the scratch becomes less visible. You can also opt for other nontoxic materials like toothpaste and water based polish to smoothen the panel. End the process by removing dust residues that gathered from the sanding.

Problem: Small Cracks and Holes

Quick Solution: Use Simple, Preventive Measures

Polycarbonate may be strong, but they are still susceptible to falling tree branches, damages from stray animals on the roof, and effects of strong weather. Small holes that can be repaired are no more than 1- 1.5 inches in diameter. To patch this up, first, clean the affected area with a soft brush or cloth to ensure that no other particles remain. Apply a generous amount of sealant to cover the area, continually smoothing it out with a sand paper or a putty knife. For best results, keep the area from being wet to give it time to dry completely.

Problem: Patchy whites on the Roof Surface

Quick Solution: Cleaning

Discoloration on the roof surface is caused by several factors, including UV damage, using improper cleaning agents, and condensation on multi wall polycarbonates like twin wall polycarbonate. In this scenario, prevention is best applied since this can make the panel look unsightly, and more often than not, the damage is irreparable especially if it is already seen largely on the panel. Using a polycarbonate panel with a built-in UV protection coating is necessary to block harmful UV rays and prevent immediate yellowing or discoloration. Block both sides of the twin wall polycarbonate during installation to keep water and insects from entering the flutes, and allow proper pitch so the water can flow down freely and prevent stagnation. Lastly, wash the sheet with warm water and a soft cloth or sponge and wipe it immediately.

Problem: Loose Panels

Quick Solution: Tighten Screws

Loosened panels are caused by changing temperatures and the roof’s response to thermal expansion and contraction. If left vulnerable and exposed, it can cause corrosion and rust eventually. Loosened panels can also cause leaks in the affected areas and are vulnerable to wind uplifts, which can damage not only the area but the neighboring panels and fasteners. To fix, remove the old screws and replace with new ones, making sure to leave a space for thermal movement.
