Installing Drip Edge On Existing Roof

Installing Drip Edge on an Existing Roof: A Comprehensive Guide

Adding drip edge to your existing roof is a relatively straightforward DIY project that offers significant benefits, protecting your roof and fascia from water damage. This guide will walk you through the process, ensuring you achieve a professional-looking and long-lasting result. Improper installation can lead to further damage, so careful attention to detail is crucial.

Why Install Drip Edge? Drip edge, a thin piece of metal flashing, is installed along the eaves and rakes of your roof. Its primary function is to direct water away from the vulnerable areas of your home, preventing water intrusion which can lead to rot, mold, and costly repairs. Protecting your fascia boards, soffits, and roof sheathing is a key investment in your home's longevity.

Assessing Your Roof Before You Begin

Before you start, carefully inspect your existing roof. Identify any damaged shingles or areas requiring repair. Addressing these issues before installing the drip edge will save you time and effort in the long run. You'll also need to consider the type of drip edge to use. Aluminum is a popular and affordable choice, while copper or zinc offers superior durability and longevity, but at a higher cost.

• Tools You'll Need: Measuring tape, hammer, roofing nails, utility knife, tin snips (for cutting metal), safety glasses, work gloves, and a ladder (ensure it's stable and rated for the height).
• Materials: Appropriate length of drip edge (measure carefully!), roofing cement (optional, for added sealing).

Step-by-Step Installation Guide

1. Preparation is Key: Begin by clearing any debris from the roof's edge. Make sure your ladder is securely positioned and you have a safe working environment.

2. Measuring and Cutting: Carefully measure the length of drip edge needed for each section of the roof (eaves and rakes). Use tin snips to cut the drip edge to the required lengths, allowing for slight overlaps.

3. Installing the Drip Edge: Start at one end of the roofline. Position the drip edge so the lip (the angled portion) faces downward, directing water away from the fascia. Secure the drip edge using roofing nails, spacing them approximately every 6-8 inches. Overlap the edges slightly for a watertight seal.

4. Working Around Obstacles: If you encounter vents, chimneys, or other obstacles, carefully measure and cut the drip edge to fit around them. Use roofing cement to seal any gaps between the drip edge and the obstacle for extra protection against leaks.

5. Completing the Installation: Continue installing the drip edge along the entire eaves and rake lines of the roof, maintaining consistent spacing and overlap.

6. Final Inspection: Once completed, inspect your work thoroughly, ensuring all nails are securely fastened and there are no gaps or loose edges. Consider applying a bead of roofing cement along any seams for an extra layer of protection against water intrusion.

Choosing the Right Drip Edge

The type of drip edge you choose will depend on your budget and the climate in your area. Aluminum is a cost-effective option suitable for most climates. Copper or zinc offer superior corrosion resistance and can last significantly longer. Consider the aesthetic of your home when making your decision.

Maintaining Your Drip Edge

Regularly inspect your drip edge for any damage or signs of wear and tear. Addressing minor issues promptly can prevent more significant problems down the line. Cleaning leaves and debris from the drip edge will help maintain its effectiveness and extend its lifespan.

By following these steps, you can successfully install drip edge on your existing roof, protecting your investment and enhancing the longevity of your home. Remember safety first! If you are uncomfortable working at heights or unsure about any aspect of the process, it's always best to consult a qualified roofing professional.
