With more that 10,000 home renovation projects we have had a lot of questions. Let’s dive into the frequently asked questions about exterior home renovation, covering replacement siding, windows, roof, and bathtub and showers:


A new roof doesn’t have to match your old roof, and the opportunity to change styles, colors, and patterning are at your discretion.

The Decking/Roof Assembly:
This is the first layer of support for your roof. Decking is made of several different materials, most often of provides plywood or OSB panels. OSB provide additional protection because shaved layers of wood are compressed with waterproof glue. This creates nearly impenetrable protection from moisture damage if higher layers are compromised.

Weatherproofing/Underlayment: The underlayer covers the frame of the roof. An underlayment is made of a waterproof membrane that acts as your last line of defense against water and your best line of defense against moisture. A poorly fitted underlayment may shrink and tear, fail to remain glued down, or leave open areas of exposure where mold can develop and get inside.

Reinforcement: Reinforcing the weatherproof membrane is key. This is accomplished using a variety of products but is most often done with a polyester, bituminous, elastomer, resin, polypropylene or hybrid layer. This is heavier than the underlayment and provides additional insulation, water-proofing, weight, and puncture protection.

Roof Covering/Surfacing: The roof covering is the final layer. That depends on your needs as a homeowner. Metal, wood, synthetic, clay, asphalt, and concrete are all viable options. Each has its own benefits and drawbacks, and we’ll help you determine which covering meets your aesthetic and durability needs. With the salt-water air coming in from the Puget Sound, we’ll often advise homeowners to stay away from metal.

We only employ roofing and siding specialists.
Too many companies try and hire jacks of every trade to cut down on costs. It might lower their costs, but it raises yours. Our roofing installers live and work off the ground. They have studied, trained, and practiced their craft, becoming veteran roofers in the process. The attention to detail and process knowledge cannot be duplicated by a multi-discipline employee.

We only use American made products.
We don’t just use American to give back to the economy and other local businesses. The U.S. crafted roofing materials we use to build your roof are designed with precision, durability, and care that other materials aren’t. This makes installation easier and helps your roof to easily reach or exceed its maximum advertised lifespan. Great materials just go further. We only use products from Owens Corning, a leading manufacturer of roofing materials. Our lines include Oakridge Shingles, TruDefinition Duration, Woodcrest, and Woodmoor.

We only install complete roofing systems.
Roofing systems do more for your home than individual components. They are designed and manufactured by a single company so that every layer works together. This improves protection over multi-manufacturer component roofs. That protection is also backed by a longer warranty. Because the manufacturer knows how those parts interact, they’ll guarantee them for a greater length of time.


There are several ways that you can prepare your home and property. These tasks can help speed up work and keep your property safe during construction.

• Clear a power outlet. The crew will need access to power for their tools, so it’s helpful to have a clear outlet available (preferably one that is on a 20-amp circuit).

• Prepare the inside of your house. Siding removal and installation will cause your walls to shake. Remove items that are leaning against or hanging on walls, and those located on shelves, as they may fall.

• Prepare the outside of your home. Move anything that may block access to your exterior walls such as firewood or patio furniture so the crew can get right to work. You should also consider removing outdoor decorations and wrapping shrubbery in landscaping canvas to prevent any accidental damage. Cutting your grass short will help your crew find nails or other debris that go astray.

• Make alternate arrangements. Construction is a loud process, which is completely unavoidable. If you work from home, you may want to consider making alternate arrangements. If you have pets, you may want to make other arrangements for them as well.

When the crew arrives, they will get oriented with your property and begin to set up work stations. Once they’re ready, their first step will be to remove your existing siding.

Some crews will only tear off one side of the house at a time to prevent leaving walls exposed to the weather. Larger crews may remove all of the siding right away.

It’s important to keep safety in mind during the re-side process. We will clean up as they work and at the end of each day, but a siding replacement project can be a messy business. Always assume there are nails on the ground and wear sturdy shoes or boots when walking in your yard while construction is underway.

During construction, we may leave scaffolding in place overnight. To prevent accidents, keep an eye on your children and warn neighbors with children to stay clear of the construction site.

The best opportunity to discover and repair damage to your home is when your old siding has been removed. These unexpected issues may seem like trouble, but it’s best to know about and fix them before your brand new siding is installed.

No contractor will know exactly what to expect without tearing off all of the existing siding. We will clearly communicate any unexpected issues.

With the James Hardie Siding Project with House Wrap we install after the siding is off and repairs are made, we may install or replace the weather resistant barrier on your home.

Finally, the crew will begin to install your new siding and trim.

Every house is different, yet a typical tear-off and siding installation project may take between 7 to 14 days. There are many things that can extend the time such as the size of your house, whether you’re using Color Plus or if it needs to be painted, and unexpected repairs. Bad weather can also be a factor and there may be some downtime waiting for building inspections. Your HPH project coordinator will keep you informed of your timeline.


Both sashes on a Double Hung window move up and down vertically and tilt in so the exterior window surfaces can be cleaned from inside your home.

A dual-pane window has an insulating glass unit that contains two panes of glass separated by a spacer and that has an airtight seal at the glass edges.

Egress requirements indicate a minimum opening size that certain windows must meet. These requirements tend to vary according to region, so please contact your local building code official for egress requirements in your area.

Our windows and doors have unique order tracking labels that are placed in the frame or sash of our products. You will need your order number when registering your warranty or submitting a form.


We do our best to minimize remodeling hassle by providing the most efficient installations on the market. Most of our shower and bath systems can be installed in just one day, but more complicated renovations might take a little more time. We would be pleased to provide an accurate estimate during your in-home consultation.

In order to help protect your bathroom remodeling investment, we’ve put together a list of recommended cleaning products and methods for your convenience.
General Cleaning Instructions
For routine cleaning, simply wipe the surface of your bath, shower, and wall surround with a soft wash cloth and warm water. We recommend using a mild soap. Use of abrasive cleaners and scouring pads will dull the surface over time. Approved cleaners are listed below. If you desire to use a different product, always review the specific cleanser’s instructions, test on a small area beforehand, and be sure to rinse thoroughly after use.
Recommended Cleaners are: BCI Preferred Cleaners, BCI Eliminate, Microban 24, Formula 409.  Vinegar and water if needed to soften mineral deposits. Use 1/2 cup Clorox Bleach per gallon of water as a disinfectant. Rinse well.
DO NOT USE: Dawn dish soap, Original Clean Shower, Clean Shower for Plastic Showers & Glass, Soft Scrub, Dow disinfectant cleaner, Dow Scrubbing Bubbles, Scrub Free, Lysol disinfectant cleaner, acetone, Lestoil, ammonia, fingernail polish remover, aerosols, or scouring pads.
Warranty Caution
Use of any cleaners or chemicals listed under “Do Not Use” will cause a dull surface and/or an easily recognizable chemical crack. This will void your product warranty. There is no need to use abrasive cleaners which can also dull the gloss over a period of years. In extreme cases where the recommended cleaners do not work, use a Chore Boy or 3M Sponge pad. Make sure you use only the ones recommended for Teflon or non-stick surfaces.
Drain Cleaner Caution
Liquid drain cleaners are recommended over powders and/or crystal; however, when using liquid drain cleaning agents, bail the standing water out of the bathtub and remove the drain plug. Use a funnel to prevent spills and apply the chemicals directly down the drain. Always make certain that chemicals do not come in contact with the acrylic surface. Use drain cleaners sparingly, so that they do not boil out and damage the acrylic surface.

Yes. Installing our wall surrounds over your existing shower or tub walls drastically reduces remodeling time and inconvenience, saving you time, stress, and money. This method is proven safe and effective, because we first repair any damaged areas in your walls to ensure a solid and secure base. We take the time needed to ensure our installations are seamless, durable, and of the highest quality.

Bathtub resurfacing provides a temporary solution that only lasts a few years, while our solutions can last a lifetime when properly maintained. Paint-on finishes are fragile, often produce a strong odor, and can take several days to dry. Our systems, which can usually be installed in just one day, are easy to clean and extremely durable.

With proper maintenance, a HPH bath or shower can last a lifetime. Our products are made with non-porous acrylic that is highly-durable and easy to maintain. Our baths and showers retain their “new” look for many years without cracking or chipping, and because our materials are a solid color throughout, discoloration or fading will never occur.

HPH is confident in the quality of our products and the professional installations provided by our certified dealers. For your added peace of mind, all of our bath and shower systems are backed with a lifetime warranty.
