New Construction: Preparing the Roof

For new construction, the foundation of the roof needs to meet specific requirements:

The roof must have a slope pitch or at least a 4-inch rise in every 12 inches of horizontal run. A solid sheathing base is necessary, with a minimum thickness of 1/2 inch. Staple an underlayment membrane to the sheathing. Begin your shingling application from the bottom to the top, ensuring a 1/2-inch overhang at the eave.

Re-Roofing with Asphalt Shingles

Re-roofing with asphalt shingles involves several critical steps:

Inspect and prepare the existing roof: Remove the old shingles, exposing the sheathing. Assess and repair any damage to the sheathing. Install an underlayment membrane. Install a drip edge to protect against water infiltration. Begin installing the asphalt shingles, following the manufacturer's instructions. Final inspection to ensure all shingles are secure and the roof is watertight.

It is crucial to follow these steps meticulously. DIY roof repairs can be challenging, and it is often advisable to consult professional roofing contractors. However, if you are determined to do it yourself, we recommend watching YouTube tutorials and closely following the instructions on the shingle packages.
