- During any roof work, ensure the sheathing is kept dry.
- When replacing a roof, leave old sheathing in place if it is in good condition, replacing only areas or sheets that are damaged.
- If replacing sheathing entirely, follow requirements for thickness given your roofing material and rafter spacing.
- Reduce your consumption through efficiency measures and behavior before evaluating renewable energy systems.
- Evaluate whether investing in a renewable energy system is practical in terms of your project goals, payback, property values, structural conditions and other considerations.
- Look into local rebates and incentives for on-site renewable energy systems.
- Hire a professional to evaluate and model your home prior to installation.
- Select roofing products with the longest manufacturer AND installer warranty.
- Pick roofing products compatible with the site:
- resistant to tree debris;
- reflective in homes with air conditioning.
- Give preference to materials with high recycled content.
- Seek alternatives to copper and zinc-coated materials, and those with built-in moss inhibitors.
- Consider maintenance needs of different roofing materials.
- Inspect your roof annually for signs of deterioration and damage.
- Look carefully at known ‘problem areas’ such as around chimneys, skylights and roof vents.
- Follow guidance for the specific plants involved in your green roof, if you have one.
Flashing & Drip Edges
- Flash to prevent leaks in valleys and wherever chimneys, ventilation or skylights penetrate the roof.
- Select powder-coated aluminum, steel or stainless steel flashing for durable products that don’t compromise environmental or human safety.
- Install aluminum drip edges along the roof’s perimeter to keep water from tracking under the eaves.
Gutters & Downspouts
- Clean your gutters regularly.
- Choose painted, seamless aluminum gutters as they will not affect water quality.
- Consider designs that minimize clogging by leaves and debris, or install leaf guard.
- Make sure gutters are installed at a slight slope toward downspouts and that downspouts discharge 6” or more from the foundation.
- Air seal building cavities before installing any insulation; it is required to achieve the full insulation value.
- Consider blown-in insulation as it typically provides better performance than batts.
- Look for fiberglass and formaldehyde-free options when buying insulation.
- Ensure your contractor can deliver “ENERGY STAR Grade 1” insulation to maximize performance.
- During installation, ensure the underlayment is kept dry. If not, the underlayment will trap moisture and damage the sheathing.
- Select 30-pound paper, as it lasts longer and provides better leak protection than 15-pound paper. Note: 30-pound and “number 30” underlayment are different!
- Consider a synthetic underlayment as a part of your roofing system – but with any component, make sure it is compatible with all other materials and especially warrantees.
- Consider breather membranes, which allow moisture to escape, for metal, tile and wood shake roofs.
- Look for recycled content underlayment.
