What Are Roofing and Siding Estimating Services?
Roofing and siding estimating services involve quantifying all materials needed to complete a roofing or siding project based on architectural drawings or specifications. These aren't just rough guesses, they’re detailed takeoffs that break down surface areas, accessories, and installation materials so contractors know exactly what to order and prepare for.
Our estimates focus on quantities only, not pricing. That means:
- Total roof area (broken into slopes, hips, valleys, ridges, eaves, etc.)
- Counts of shingles, panels, tiles, underlayment, and flashing.
- Siding square footage, waste allowances, trim, and fastening materials.
- Gutter, downspout, fascia, and soffit quantities, if needed.
What We Provide
We have experience in estimating every single type of roofing material used in construction, from roofing shingles to flat roofs.
We will give you a list of material quantities in Excel with a colored PDF markup of the estimate and the software file if required. This is great for checking and installation, but also for showing clients.
We also compare elevations to roof plans and make sure there are no discrepancies that can cost you later on.

We work with all major roofing systems and materials, including:
- Asphalt shingles
- Metal panels

We don’t just measure surface areas, we also factor in:

How often should a roof be replaced?
The lifespan of a roof really depends on the type of material used. Here’s a general guideline:
- Composition shingles typically last between 12 to 20 years.
- Asphalt shingles usually hold up for 15 to 30 years.
- Wood shingles can last around 20 to 25 years.
Keep in mind that weather conditions, installation quality, and maintenance can also affect how long a roof holds up.
