A New Roof Can’t Wait
There so much to learn when considering a new roof. There are already two existing layers of roofing material on the house, clearly some damage and we suspect some rot. For the new roof to be up to code we will have to remove the old shingles and replace with new shingles, repair any water damage and rotten wood. Additionally, whenever a new roof is installed new underlayment (roofing felt) to create a moisture barrier between the roofing and the wood sheathing and rafters underneath is required. We considered the potential of hurricanes in Charleston, extreme heat and warranties when researching our product choice.
Architectural vs. Three Tab Shingles
Three-tab shingles are distinguished by cutouts—tabs—made along their long lower edge. Each shingle looks like three separate pieces when installed, but it’s only one. Three-tab shingles have been around a long time and are still the most economical and most popular shingle today.
Architectural asphalt shingles contain no cutouts, but their lower portions are laminated with an additional asphalt layer. This creates the contoured, dimensional look that gives them their name. Asphalt sealant bonds the layers, reinforcing the shingles’ waterproof capability. Though durable, architectural shingles are not recommended for low-sloping roofs, which are more vulnerable to wind-driven rain.
The Decision – Architectural Shingles
- Aesthetics. Architectural shingles are better able to hide imperfections on the roof surface.
- Durability. Architectural shingles are nearly twice as thick as three-tab shingles and are therefore more durable and less vulnerable to curling.
- Weight and wind resistance. Three-tab shingles usually weigh 240 lbs per square and are rated for wind speeds up to 60 mph; architectural shingles weigh 340-440 lbs per square and are rated for wind speeds up to 80-120 mph.
- Manufacturer’s warranties. 25 years for three-tab, 40 to 50 years for architectural.W
We spent much of the day pricing roofing material only to land at Lowe’s (https://www.lowes.com/pd/Owens-Corning-Oakridge-32-8-Sq-Ft-Onyx-Black-Laminated-Architectural-Roof-Shingles/3005314) for the purchase.
Because Steve is a veteran and he gets 10% off our purchases we found our best prices at Lowe’s, yes, his favorite store. The roofing material is purchased and delivery is set for Thursday morning.
We found a roofing company on Craig’s List and the work is scheduled to begin Friday and finish Saturday. Wow, the plan is working out, there’s nothing like being on schedule. We spent the remainder of our day clearing the house.
